1 Battery and charging

1.1 What is my phone's temperature rise? 1. Your phone meets the international standards and its temperature rise is lower that most products of its class in the industry. 2. If the customer requires specific statistics, explain the standards in detail (the hotline personnel shall not directly describe the statistics to the customer): Based on the EN 60950-1, the maximum temperature for metal is 60 degrees, glass 70 degrees, and plastics 85 degrees for short-term contact; the maximum temperature for metal is 55 degrees, glass 65 degrees, and plastics 75 degrees for long-term contact.

1.2 Why does my phone generate heat when I am using it? It is normal for a smartphone to generate heat when it is consuming its battery power. Android phones allow multiple applications to simultaneously run in the background. However, some third-party applications keep connecting to the network or running in the background, which consumes battery power. Generally your phone's temperature gets higher as it consumes more battery power. When you sense obvious heat generated by your phone, check whether your phone's power consumption is normal (Settings > Power saving > Background power-intensive apps). Close power-intensive apps not in use if any. To prevent your phone from generating excessive heat due to sunlight, don't use your phone for a long time under sunlight in summer or place your phone on the front of your car under sunlight for navigation purposes.

1.3 Why does my phone generate excessive heat when I watch videos? Video players differ in power consumption due to different codecs. It is recommended that you use a hardware codec with low power consumption. The pre-installed gallery and video player on your phone have low power consumption and generate less heat. It is recommended that you use the pre-installed video player (choose the advanced player when playing videos). Don't watch videos while your phone is charging.

August 2015 24 INTERNAL

1.4 What can I do if my phone generates heat when I browse web pages? 1. To reduce heat generated by your phone when you are surfing the Internet, make sure the signal strength occupies at least three bars. 2. Use the native browser to surf the Internet. 3. If you are using a third-party browser, set it to no-picture browsing mode.

1.5 What can I do if my phone generates excessive heat when I am playing games? Games consume more battery power than calls, videos, and music. It is recommended that you don't play games while your phone is charging. Also you can close all background applications when you are playing games or set the volume level to medium to reduce the heat and increase your phone's battery life.

1.6 Why does my phone generate excessive heat when I am playing songs? It is normal if you feel that your phone is overheated when you are listening to songs with the screen turned on, especially in hot weathers. Your phone's music playback quality has been improved and more heat may be generated while songs are playing. Therefore, don't play songs through the speaker for a long time at a large volume. However, your phone may generate excessive heat if you are listening to songs while downloading music files and performing other operations on your phone's screen. So don't download music files or perform other operations while you are listening to songs.

1.7 Why does my phone generate excessive heat when I am making phone calls? The heat generated by your phone increases rapidly when the signal reception is poor. Your phone provides the industry leading heat control function for calls. If you still feel that your phone generates too much heat during calls, check whether your phone's reception is poor. To reduce the power consumption and heat generated by your phone, it is recommended that you don't keep your screen on for a long time during calls, or charge your phone during calls.

1.8 What can I do if my phone generates excessive heat? 1. Enable power saving mode.

August 2015 25 INTERNAL

Go to Settings > Power saving and choose a power saving mode. To properly allocate your phone's battery power, it is recommended that you choose smart power saving mode for normal use and ultra power saving mode when your phone's battery level is low. 2. Close applications that consume too much batter power. To check the power consumption of your applications: Go to Settings > Battery >Consumption level and check the power consumption of each application. If you don't often use the applications that consume much battery power, close them. 3. Close background applications. Touch the Recent button on the navigation bar, and then swipe on the applications not in use to close them. 4. Close applications that are running at the same time. To close applications that are running at the same time, go to Settings > Manage apps > Running and touch the applications not in use to close them.

To reduce the time for the screen to go to sleep when the screen is idle: Go to Settings > Display > Sleep and set a shorter time for the screen to go to sleep. 8. Set the screen brightness to an appropriate level. If your screen brightness level is too high, it consumes too much battery power and may hurt your eyes. To lower the screen brightness level or set your phone to automatically adjust its brightness, go to Settings > Display > Brightness, and drag the brightness bar to a proper position or enable Automatic brightness. You can also flick down from the status bar and drag the brightness bar to adjust the screen brightness. 9. Close power-intensive applications that are running in the background. Your phone is provided with the function of power consumption monitoring and reminding for background applications. If the power-intensive applications are running in the background, a battery icon is displayed in the upper left corner of your phone. Flick down from the top of your screen to display a screen with white background, touch the battery icon to display a list of power-intensive applications that are running in the background, and close the unwanted applications. 10. Update your phone to the latest version. Updates are available for your phone from time to time to optimize the power saving settings. It is recommended that you use the online update feature to update your phone to its latest version. To update your phone, go to Settings > Updater > Check for updates and select the online update option. 11. Save your battery power. When you are not using the phone, press the power button to turn off the screen.

Set the screen timeout period to a small value under Settings > Display > Sleep. Lower the screen brightness under Settings > Display > Brightness. Turn off Wi-Fi and Bluetooth when you don't need to use them under Settings >Wi-Fi> and Bluetooth. Close unimportant third-party application notifications. Go to Settings > Notification center and disable the permission for unimportant third-party application to send notifications to you. Close protected applications under Settings > Protected apps. Turn off data synchronization in the background. Go to Settings > Accounts. Then turn off the synchronization. Turn off the mobile network by clearing Mobile data under Settings > More > Mobile networks. Turn off GPS by clearing Access my location under Settings > Location access.

1.9 Does my phone generate heat due to its poor quality? Your phone generates heat due to multiple reasons, such as excessive current, unstable network, and high ambient temperature, which has nothing to do with your phone's quality. Two pieces of graphite are provided to assist your phone's heat dissipation. The heat dissipation architecture is carefully designed and tested to bring you the optimal experience. Your phone is also equipped with the Huawei dedicated power saving technology and overheat protection for the circuits.

1.10 Why does my phone generate excessive heat even when I am not using it? For normal heat generation: Your phone generates relatively less heat when you make phone calls and send messages with normal signal reception and more heat when you take photos or shoot videos, play games that consume much battery power, surf the Internet, and download images or files. For exceptional heat generation: If your phone generates excessive heat at a certain time or during standby time (at the center of your phone and the frame near the power button) and the battery life is obviously shortened, some applications in your phone are consuming extra battery power. Solutions to exceptional heat generation: 1. Close unwanted power-intensive applications under Settings > Power saving > Background power-intensive apps. The third-party guardian software continuously takes up your phone's CPU resources, which may also result in excessive heat and high power consumption. 2. If the preceding solution doesn't work, restart your phone.

August 2015 28 INTERNAL

3. If the preceding solution doesn't work, back up important data and restore your phone to its factory settings.

1.11 Why does it take a long time to charge my phone? 1. Make sure the two ends of the data cable are properly attached to your phone and the charger. 2. If you are using a small-load charger and a computer USB cable (that generally has a limited current of 500 mA), the charging current is small, resulting in a long charging time. It is recommended that you use the 5 V 2 A charger that comes with your phone. 3. Quickly reconnect your phone to the charger and make sure the charging cable connector is properly inserted to your phone. Reinsert the charger to the charging dock and make sure the charger is properly inserted to the charging dock. 4. If the problem persists, take your phone to an authorized Huawei service center.

1.12 Why does it take a long time to charge my phone when it is generating excessive heat? Your phone is provided with the Huawei's unique overheat protection. When your phone is overheated, it will limit the charging circuit. You can close some applications such as video and games, or power off your phone. After your phone's temperature decreases, your phone can be charged properly.

1.13 Why does my phone sometimes repeatedly restart after it is connected to a charger and powered on? When your battery is over discharged, the power supply is insufficient when your phone is connected to a small-load charger, resulting in insufficient current that causes the repeated restarts of your phone. Use the charger that comes with your phone to provide sufficient current for your phone.

1.14 How do I save my phone's battery power? 1. Set your phone to close unwanted applications when you turn off the screen. Choose Settings > Power saving > Protected apps and deselect the power-intensive applications and other unwanted applications. Then the deselected applications will be automatically closed after the screen is turned off. 2. Adjust your screen brightness. Go to Settings > Display > Brightness and drag the slider to lower the screen's brightness. 3. Reduce the time for the screen to go to sleep when the screen is idle.

August 2015 29 INTERNAL

Go to Settings > Display > Sleep and set a shorter time for the screen to go to sleep.

1.15 Will the indicator respond when my phone's battery level is lower than 10%? When the battery level is lower than 10% but higher than 2%, the LED is turned off, the indicator doesn't blink, and event reminding will not be affected. When the battery level is lower than 2%, the indicator is blinking red.

1.16 What can I do if my phone's standby time is short? 1. Set your phone to close unwanted applications when you turn off the screen. Close unwanted power-intensive applications under Settings > Power saving > Background power-intensive apps. Alternatively, you can choose Settings > Power saving > Protected apps and deselect the power-intensive applications and other unwanted applications. If some applications are needed in the background, they can remain unclosed. This method helps save battery power after the screen is turned off by reducing the number of power-intensive applications that are running in the background. 2. Adjust the screen brightness. Go to Settings > Display > Brightness and drag the slider to lower the screen's brightness. Use this method based on your actual situations. The screen consumes relatively much power, so this method can help reduce the power consumption of the screen. 3. Close unwanted background applications. Touch the Recent button and swipe on the applications not in use to close them or touch the brush icon to close them. Go to Phone Manager > Traffic manager > Traffic use ranking and deselect the mobile data check boxes of the programs that are used only with Wi-Fi. 5. Close third-party applications that are running in the background. You can also back up important data and restore your phone to its factory settings. Make sure your phone is in an area with good reception. Your phone consumes more power when the signal is not strong enough.

1.17 Why is my charger overheated when charging my phone? The temperature rise of a charger is around 30 degrees, which means that the charger temperature will not exceed 55 degrees under room temperature. Therefore, it is normal that you feel the charger is overheated, especially if you are temperature-sensitive. If you are not assured, take your charger to an authorized Huawei service center.

6.2 Fingerprint identification 6.2.1 Why does the fingerprint unlock feature frequently fail to work properly? The fingerprint sensor on Huawei phones is designed to work at temperatures ranging from –20℃ to +75℃. If the fingerprint sensor fails to recognize your fingerprint, this is usually due to the ambient conditions. This problem is normally observed during cold periods when the finger's skin is susceptible to peeling, causing temporary changes in the shape of your fingerprint. In addition, the fingerprint sensor may also not work properly late at night or when you wake up in the morning due to changes in the depth of fingerprint ridges caused by dry fingers and slow circulation. 1. Check whether the skin on your finger is dry, peeling or damaged.

August 2015 139 INTERNAL

The fingerprint sensor is designed to work at temperatures ranging from –20℃ to +75℃. Solutions: Use another finger. Use skincare products to keep your skin moist and prevent it from peeling or cracking. If you are suffering from dry skin, exercising or using warm water to wash your hands can help to relieve the problem. 2. Check whether the surface of the fingerprint sensor is dirty and clean it if necessary. 3. If the fingerprint sensor is still not working properly, check whether your phone vibrates when you use the sensor. If so, this means that your phone did not recognize your fingerprint and the screen was not unlocked. Solutions: Try to cover the whole of the fingerprint sensor with your fingertip. You can record 6 images for each fingerprint - two for the center of each fingerprint (the most commonly used part) and 4 for the surrounding areas. The greater the surface area you record, the greater the accuracy of the fingerprint sensor. Try registering your fingerprint again following the steps above. When registering your fingerprint, avoid using the same area of your finger for each of the 6 images. 6.2.2 Why does it takes a long time to unlock the screen after my phone has been used for a certain period? 1. Your fingers may become dry in autumn and winter. In this case, you can press your finger against the fingerprint sensor more strongly and keep your finger moderately humid by blowing hot air to it or washing it. 2. The blood circulation speed decreases when you sleep and the fingerprint pattern gets shallower. Even though the fingerprint characteristics remain unchanged, it may feel smoother. In this case, you need to press harder. 3. The working temperature of the fingerprint sensor is from –20°C to +75°C . 6.2.3 What can I do to successfully unlock the screen even if my fingers are dry? When your fingers are dry naturally, in dry seasons (autumn and winter) or areas (plateau areas), during rests, or after you carry heavy objects, you may fail to unlock the screen using your fingerprint. Fingerprints can increase the friction between your finger and the object you want to grab. If your fingerprint is too dry, the friction will decrease. Solution: 1. Press your finger against the fingerprint sensor more strongly. 2. Keep your fingers moderately humid by blowing hot air to it or washing it.

August 2015 140 INTERNAL

6.2.4 What can I do to successfully unlock the screen even if my fingers are wet or easy to sweat? If your fingers are easy to sweat or still wet after you wash your hands, you may fail to unlock the screen using your fingerprint. To solve this problem: Wipe your fingers with tissues and ensure that your fingers are free of water or sweat. 6.2.5 Why does my phone fail to read my fingerprint? 1. Your phone may fail to read your fingerprint if your finger is too dry, sweaty, wet, or has obstacles. Wipe your finger and try again. If your fingers are dry, you may need to press your finger against the sensor more strongly. 2. You can try enrolling your fingerprint again. While you are enrolling your fingerprint, use the gesture you often use, enroll your fingerprint areas as many as possible, and avoid enrolling the same area of your fingerprint, so that the enrolled fingerprint image will be consistent with that read by your phone when you press your finger against the fingerprint sensor. 3. Make sure the finger area you press against the fingerprint sensor is the same as that you enrolled to your phone. It is recommended that you use the gesture you often use while you are enrolling your fingerprint. 6.2.6 Why do people whose fingerprint patterns are shallow often fail to unlock the screen using the fingerprint? Females and children's fingers are slim and their fingerprint patterns are shallow. 1. Slim fingers may not be able to touch the edges of the fingerprint sensor, which may result in incorrect fingerprint image collection. The edges of your phone's fingerprint sensor provide a weak but stable electricity signal. When a finger touches the edges, the sensor generates sensing capacitance on its surface to produce the fingerprint image. If the finger doesn't touch the edges properly, the image quality may be poor. 2. Shallow fingerprint patterns may also cause fingerprint images with poor quality. To solve this problem: Use the finger pad to cover the whole fingerprint sensor and its edges to enroll clear and stable fingerprints. 6.2.7 Why does the fingerprint sensor often fail to recognize my fingerprint and respond slowly when I'm unlocking the screen? Circulation in your fingers will deteriorate when in high-altitude locations, when sedentary or when lifting heavy objects, resulting in dry skin and therefore slight changes to the shape of your fingerprint. Refer to the solutions for dry skin above, e.g. press slightly harder on the fingerprint sensor and keep your skin moist by breathing onto your fingers or washing your hands and then wiping them dry. 6.2.8 Why can I unlock the screen using multiple fingerprints? 1. Your other fingers may have accidentally touched the fingerprint sensor when you were enrolling your fingerprint.

August 2015 141 INTERNAL

You can enroll six fingerprint images in total. However, it is not recommended that you enroll multiple fingerprints for the same mode. 2. You may have enrolled the fingerprints in visitor mode. Go to Settings > Fingerprint ID for check. 3. If the problem persists, delete all the fingerprints in owner and visitor modes, restart your phone, and enroll your fingerprint again. 6.2.9 Why can't I unlock my phone using my fingerprint until I restart my phone? Check the frequency of such a problem. This problem is caused by a software defect other than the hardware of the fingerprint sensor and your phone, please pay attention to the follow-up version instructions. 6.2.10 Why can't I unlock the screen using my fingerprint after my phone is connected to a charger of another brand? Please use the standard charger that comes with your phone. Non-standard chargers have different anti-interference capabilities. The interference from the charger power supply will affect the performance of the fingerprint sensor, resulting in changes of fingerprint images. 6.2.11 Why can't I unlock the screen using my fingerprint? Why can't I find the fingerprint option under Settings? When you can't unlock your screen using your fingerprint, go to Settings > Privacy & security and check whether there is a fingerprint option. If no, restart your phone and check whether the fingerprint option exists. If you can't find the fingerprint option under Settings, take your phone to a nearby service center for detecting.

August 2015 142 INTERNAL

The figures are for your reference only. The actual screens may vary. 6.2.12 Why do I have to enroll my fingerprint for several times and from different angles? This is normal. Your phone can record a large area of your fingerprint after you enroll your fingerprint for several times and from different angles. It will be easier for your phone to read your fingerprint if the fingerprint area recorded is larger. 6.2.13 Why can I unlock my screen even if my finger is not perfectly aligned with the fingerprint sensor? Your phone's fingerprint sensor has an identification angle of 360 degrees, so it can read your fingerprint even if your finger is not perfectly aligned with the sensor. 6.2.14 How do I unlock the screen using my fingerprint?

6.2.19 How can I use the fingerprint sensor to complete a payment? After you have linked your fingerprint to your Alipay account, you can make a payment using your fingerprint without entering your account password. 6.2.20 Is it safe to make a payment using my fingerprint? Using your fingerprint to make a payment is an extremely secure payment method, as evidenced by Alipay's willingness to cooperate with Huawei. In addition, Alipay provides full compensation in the event of any security problems. Compared with previous fingerprint payment methods where verification data was sent to third parties, this new payment method released by Huawei and Alipay analyzes all fingerprint data on the phone's local security system for added security. Huawei uses chip-level TrustZone technology - all fingerprint data is managed, encrypted, verified and stored within TrustZone's own bespoke operating system. Android and third-party apps are not able to access this isolated part of the system, ensuring that your fingerprint information stays secure. 6.2.21 How do I use the safe function? 1. On the home screen, touch Files. 2. Agree to the user agreement before you start using the safe. 3. Under Categories or Local, touch Safe. 4. Touch Start. 5. Follow the onscreen instructions to enter the password and answers to security question, and then touch Done. 6. Touch Move in and follow the onscreen instructions to choose files to be protected. 6.2.22 Why do I have to record my fingerprint for several times? 1. This is normal. Your phone records a large area of your fingerprint after you enroll your fingerprint for several times. It will be easier for your phone to read your fingerprint if the fingerprint area recorded is larger. For example: If you have enrolled four different areas of your fingerprint, you can use any one of the areas to unlock your phone. Therefore, when you are enrolling your fingerprint, the enrolling screen will tell you to enroll the center and edges of your finger for several times. Your phone has a fingerprint identification angle of 360 degrees. You can press your finger against the fingerprint sensor from any angle to enroll your fingerprint. A total number of six fingerprint images will be enrolled. If any image is unqualified, your phone will ask you to enroll again. These fingerprint images are for the convenience of fingerprint identification to unlock your phone. 2. The fingerprint sensor is pressure-sensitive. There is a weak signal surrounding the depressed fingerprint identification area. When you press your finger against this area, your fingerprint is transmitted to the contact surface for identification and detection. For woman users, use the finger pad to press against the fingerprint sensor and make sure the edges of your finger are fully enrolled, for the convenience of easy unlock.

August 2015 144 INTERNAL

3. Fingers may be dry or wet (oily and easy to sweat). If your finger is dry, to avoid unclear fingerprint images, you need to press your finger against the fingerprint sensor more strongly. If your finger is wet, easy to sweat, or oily, it is recommended that you use tissues to wipe your fingers before you enroll your fingerprint. 4. If the fingerprint sensor or your finger is dirty, your phone may fail to read your fingerprint. Check that there is no dust, sweat, or other smudges on your finger or the fingerprint sensor. Clean your fingerprint sensor, if necessary. 6.2.23 Why can't I unlock my phone using my fingerprint? 1. Go to Settings > Fingerprint ID and check whether you have enrolled your fingerprint. 2. If you have enrolled your fingerprint, go to Settings > Fingerprint ID and check whether Unlock screen has been enabled. 3. Make sure you use the correct finger to unlock your phone. For example, if you have enrolled the fingerprint of your index finger but use the middle finger to unlock your phone, your phone can't be unlocked. 6.2.24 Why can't I enroll my fingerprint successfully? 1. Don't move your finger while you are enrolling your fingerprint to ensure clear fingerprint images. 2. Keep your finger clean without water or obstacles. While you are enrolling your fingerprint, use the gesture you often use, enroll your fingerprint areas as many as possible, and avoid enrolling the same area of your fingerprint, so that the enrolled fingerprint image will be consistent with that read by your phone when you press your finger against the fingerprint sensor. 6.2.25 Why does my phone read my fingerprint slowly in the morning or at midnight? Your finger gets dry when you are asleep, which makes it hard for your phone to read your fingerprint. After you wake up, your body will adjust the humidity of your skin and your phone will be able to read your fingerprint at a normal speed. 6.2.26 Why can't I use my fingerprint to unlock my phone when a third-party screen lock application starts? To ensure fingerprint security, your phone's fingerprint service is not open to third-party applications and the fingerprint service can't be implemented on third-party applications. 6.2.27 Why can't I unlock my phone or enroll my fingerprint when I swipe my finger on the fingerprint sensor?

At this time, the charging indicator will be off and your phone stops charging the headset. 3. However, if you set your phone not to charge the headset, the headset's microphone can't pick up voice. Therefore, the preceding method can be used if you are using the headset only to listen to songs. If you want to make phone calls using the headset, you have to reinsert the headset.

7.15 Why is the sound not stable when I play songs in speaker mode at a small volume (two to three bars)? Your phone is designed this way to bring you a better music experience. The sound details are ensured even when you are playing songs at a small volume. However, your ear is so sensitive to sounds that the changes of sounds at a small volume can also be sensed, which is a normal phenomenon.

August 2015 150 INTERNAL

7.16 Why can I hear noise or current noise when I play songs in speaker mode at the minimum volume? 1. The speaker is a large-power component, which is driven by a PA. When the volume is reduced to the minimum, the PA is still working and outputting certain noise floor (similar to a home theater at the minimum sound volume). When your ear is close to the speaker, you can hear that noise, which is the noise floor of the speaker circuit. It is recommended that you do not place your ear close to the speaker to protect your ear. 2. Your phone adopts the third-party sound effect commissioning algorithm in terms of the speaker sound effects. When the volume is set to the minimum, the algorithm filter's deviation will be output through the speaker, that is, the current noise, which is a normal phenomenon.

7.17 How do I modify the application that I use to share photos? Check whether any applications that can be used to view photos are installed on your phone, because they may keep the sharing function of a certain application always on. Touch Settings > Manage apps > Default app settings to restore to the default settings.

7.18 Why is the date in Gallery several years ago? The default date of your phone is January 1, 2011. If you haven't modified or updated that date, it will remain on your phone. If any photos are taken, the date of the photos will be the default date, which is a normal phenomenon. It is recommended that after you purchase the phone, insert a SIM card and register with your carrier's network to obtain the latest date.

7.19 Why is there light leakage around the battery cover after I turn on flash? To achieve a more crystal-like visual experience, your battery cover is attached with a transparent PET film that has a light guide effect. Therefore, when you turn on flash, there may seem light leakage around the battery cover, which doesn't affect your camera's functions.

7.20 Why isn't music paused when I answer calls? This is a caused by third-party applications. When the music focus is taken from the third-party music player or applications by other applications, no pause control is made. To solve this, update the third-party music player's version.

7.21 Why isn't there a ringtone for incoming calls after I set the volume to the maximum? Third-party applications, such as WeChat, may occasionally block your phone's audio channel, so other applications fail to normally play sound, such as incoming call ringtones. Close the third-party application in question that is running in the background, or restart your phone.

7.22 What can I do if I can't use the snapshot function? 1. Make sure your phone's screen is turned off. 2. Make sure no music is played.

7.23 Why are the photos I take in ultra snapshot mode not as good as the photos I take in normal mode? In some extreme scenarios, such as a dark environment or close-up shots, the shooting speed in ultra snapshot mode is very fast, so the image colors and clarity of the photos are not as good as those taken in normal mode.

August 2015 152 INTERNAL

7.24 Why can't I open the camera on my phone? Some applications related to the camera, such as the flashlight, may have been opened. Close those applications and try again.

7.25 Why is the volume of the recorded video small? You may have recorded the video too far away from the recorded objects. It is recommended that you record a video within 2 meters away from the recorded objects.

7.26 Why does it take longer to focus when I take photos at a short distance from the object than when I take photos at a long distance from the object? Generally, users take photos one meter away from the object, so by default, your phone starts scanning from the distant area. If the object is close to you, it is normal that it takes longer for your phone to focus from the distant area to the object.

7.27 Why is the photo focus unclear when I take a photo in a dark environment? Your phone may not be able to identify the details of the image in a dark environment. If the focus area has no detail with obvious color contrast, the image is harder to identify, which decreases your phone's focus performance. This is normal. You need to focus for several times or manually choose the area with obvious color contrast to focus.

7.28 Why does the photo become vague after I zoom in? When you are viewing a photo, your phone allows you to zoom in to a large extent. If you keep zooming in until one image corresponds to multiple screen pixels, the photo becomes vague, which is normal.

7.29 Why is my phone severely overheated after I take photos or shoot videos for a certain time period? To achieve better image quality, your phone adopts a single-lens reflex level image processing chipset, which consumes relatively much battery power, and your phone's capabilities of heat dissipation is limited due to its size. Therefore, if you keep shooting photos or videos for a certain time period, your phone will be obviously overheated.

August 2015 153 INTERNAL

However, your phone is provided with an overheat protection. Your phone will not be damaged.

7.30 Why are the photos I take using the front camera reverse? The mirror reflection function is enabled by default for your front camera. So photos taken by the front camera are reverse, which are consistent with previews. If you want to save photos of the actual scenario, disable the mirror reflection function.

7.31 Can I modify watermark images? Yes, but you can only modify the several pre-installed watermark images by swiping left and right on the screen. You can edit the watermark texts but can't change the watermark orientation.

7.32 Why do I see a gap when I tilt my phone and look into it through the flash lens? The flash center overlaps with the lens optical center, which doesn't affect the performance. The gap you see is attached with an anti-dust silicone cover to prevent dust from coming into your phone.

7.33 Why do photos taken at night have speckled pixels? For clearer dark details in photos you take in a dark environment, the ISO value has been increased to increase the photo brightness, which at the same time enhances the noise. We think it's better to increase the photo brightness for clearer dark details, regardless of the noise.

7.34 Why do videos taken near lights have ripples? The lights are powered by alternating current with a certain blinking frequency. If the blinking frequency and the camera's scanning frequency do not match, ripples appear. Since the commercial electricity frequencies vary by country and area, to realize compatibility, your phone needs to identify the actual commercial electricity frequency in real time, resulting in ripples if shooting scenes change. If your phone is near the light source or the shooting scenes change during video recording, ripples may also occur, which is normal.

August 2015 154 INTERNAL

7.35 Why does my face look thinner and my eyes bigger in my selfie? Your phone provides a beauty mode, which automatically makes your face thinner, eyes bigger, and appearance more beautiful. When you take a photo using the front camera, beauty mode is turned on by default. You can adjust the beauty mode settings from Settings.

7.36 Why is the photo of a moving object blurred? A certain exposure time is required to take a photo. During the exposure time, if the object moves and is captured by your camera, the photo is blurred.

7.37 Why is the image on the viewfinder blurred until 2 to 3 seconds after I open the camera? When the camera is turned off, it focuses at an infinite distance. After you turn on the camera, it will wait until the viewfinder becomes stable to start focusing. This process takes 2 to 3 seconds.

7.38 Why does the photo of bulbs I take at night have radial halo? Your phone is installed with glass to protect the camera. If you touch the glass or make the glass dirty, the radial halo occurs in the photo of bulbs. To eliminate the radial halo, wipe the glass with a cleaning cloth.

7.39 Why is the photo of a night scene still dark even after I turn on flash? The LED strobe lamp has limited brightness, so sometimes the strobe lamp may not be able to complement the brightness of the dark scene, which is normal. When you are using the flash, do not block the light with your fingers or the decorations of your phone. Otherwise, the photo you take may be blurred.

7.40 Why is the viewfinder red when I cover the camera with my hand? If the lights are strong and you cover the camera with your hand, the blood in your hand will be reflected to your camera and make the viewfinder red. If the lights are weak and you cover the camera with your hand, the viewfinder will be black.

August 2015 155 INTERNAL

7.41 Why is the photo taken with flash on blurred? Possible reasons include: 1. You may have put your hand near the flash that reflects certain lights, resulting in bad image contrast ratio. Try moving your hand away from the flash area and check whether this problem persists. 2. Your phone's PC cover may be near the flash that reflects certain lights. Remove the PC cover and check whether this problem persists.

7.42 Why do the photos I take with flash on have red eyes or bright spots? If the environment brightness level is low, pupils of human eyes dilate, and the light of the flash passes into the eye through the pupil and reflects off the fundus at the back of the eyeball and out through the pupil, resulting in the red-eye or bright spot effect, which is a normal phenomenon. To avoid this, you can try staring at lights for a while to shrink your pupils.

7.43 Why can't I find the photos I take after I set the default storage location for photos to the external microSD card? Reasons include: 1. The external microSD card is damaged, so the content stored in the card can't be read. To avoid the problem, replace the damaged card. 2. The external microSD card may not have sufficient storage space and the photos may be automatically saved to the DICM folder in the internal storage.

7.44 Why doesn't beauty mode work for burst shots? Your phone doesn't support beauty mode for burst shots.

7.45 How is the time displayed on the ultra snapshot screen calculated? This time value consists of the time taken to preview the scene, the time for automatic white balance (AWB) and luminance stability, and the time for taking the photo. The major element that affects this time value is the time for AWB and luminance stability.

August 2015 156 INTERNAL

White balance makes digital cameras recognize the white color and balance other colors under colored lights regardless of the surrounding lights. Colors are in essence the explanation toward lights. An object that seems white under normal lights may not seem so white under dark lights. An object that seems white under fluorescent may also not be so white. Therefore, if white balance can be achieved, other non-white colors on photos can be restored with the base color of white.

7.46 Why do the photos I take with flash on have color cast?

 You may have covered the camera or flash with your hand or your phone's leather case or screen protective film, resulting in unclear images and color cast (an obvious tint of blue or yellow). To solve the problem, remove the obstructing object from the camera or flash.  The colors of the photo taken with flash on are inconsistent with the colors of the photo taken with flash off. The photo taken with flash on has a deeper tint of yellow, because a light source with a different color temperature appears in addition to the existing ambient light source when the flash is on. This is normal. You may need to update your phone to the latest version.  Try restoring to the default settings.  You may have made the protective lens of the camera or flash dirty that reflects certain lights, making the photos look glary and foggy. Remove your phone's PC cover and wipe the lens with a cleaning cloth.

If the problem persists after you have wiped the lens clean, please use a PC cover purchased from Huawei's online store.

7.47 Why does the video recording suddenly stop? The recorded video file's size may exceed 4 GB.

7.48 Why does it take a long time to open Gallery after I take photos? Your phone performs a large number of algorithm-based image processing operations on the background to achieve optimal photo effect. The image processing may take a long time, causing a delay in opening Gallery. Please wait for several seconds.

7.49 Why is the clarity of the viewfinder not good? Your phone is provided with the best viewfinder clarity in the industry. The clarity appears lower on the large screen of your phone.

August 2015 157 INTERNAL

7.50 Why do the photos taken on some scenes appear bright while the photos taken on other scenes have obvious bright and dark contrast? Your phone employs the high dynamic range imaging (HDR) technique. It automatically starts HDR when the shooting object contains a scene with obvious contrast, resulting in bright photos with visible details in the lightest and darkest areas. It doesn't start HDR when the shooting object contains a scene with a low degree of contrast, resulting in photos with obvious bright-and-dark contrast.

7.51 What can I do if I see black spots and smudges on the viewfinder after I use the camera for several months? 1. Wipe the rear protective lens of the camera clean and make sure the lens is clean. Also check that the protective lens is not scratched by other sharp objects. 2. If you still see smudges, you may have dropped your phone and damaged the camera. Those black spots and smudges may be caused by the scraps inside the camera. The camera module is a precision component and can't be opened, but you can face the phone screen in front of you and hold your phone with your right hand while keeping your left hand unmoved. Flap the phone against your left hand to shake the scraps outside the imaging area of the camera. 3. If the problem persists, take your phone to a nearby maintenance outlet for repair.

7.52 Why is the photo focus unclear after I dropped my phone to the ground? The focusing assembly of your phone's camera is a precision component.

7.107 Optical image stabilization (OIS) 7.107.1 What can I do if the camera fails to focus, shadowing occurs, and the preview shakes when I take photos using the OIS camera? Your phone supports OIS. Check whether the decoration on your phone's leather case or protective cover is made of metal or magnetic materials. Non-magnetic materials are recommended. In addition, check whether your phone has been severely dropped or placed in a strong magnetic environment. If so, take your phone to a maintenance outlet for check. 7.107.2 Why can't the stabilization function work properly on a bus or in the subway? This is normal. Your phone is provided with the best compensation in the industry. However, due to the limited stabilization range of your camera, when the compensation range is exceeded, the stabilization effect can't be guaranteed. 7.107.3 Why is the viewfinder blurred when I am shooting a moving object? The OIS feature of your camera compensates the shaking of your phone but not the movement of the object. Therefore, if the object moves, the image may be blurred.

August 2015 172 INTERNAL

7.107.4 Why are the photos still blurred even if my phone is provided with a OIS camera? The OIS feature of your camera compensates the shaking of your phone but not the movement of the object. Therefore, if the object moves, the image may be blurred. 7.107.5 What are the differences between the RGBW sensor and the RGB sensor? Compared to the RGB sensor, the RGBW sensor provides the recording point of the white color, so more color information can be recorded. This feature brings better SNR in dark environments. 7.107.6 Why is the image drifting in preview, especially in digital zoom mode? The OIS lens compensates the movement of your phone when you are shooting photos. However, due to the limited precision of the movement detection component (gyroscope) and the uncertainty of your phone's moving track, slightly unnecessary compensation will be caused. Therefore, the image will be slowly drifting in preview mode or when it is zoomed in to the maximum using digital zoom with your phone held in your hand, which is a normal phenomenon that can happen in all phones in the industry, which are enabled with the optical stabilization function in preview mode. If this affects your shooting, you can turn off the optical stabilization function.

7.114 Why does ultra snapshot still work when the screen is turned on? In ultra snapshot mode, when the screen is turned off, you can double press the volume button to take a snapshot. This function works when the screen is turned off for the purpose of quickly take a photo without accessing the camera.

7.115 Why can't I find the photos I have taken in Gallery? There are three tabs in Gallery, Photos, Albums. Check that you are on the Photos tab.

7.116 Why can't ultra snapshot work? You may be playing music and the volume buttons are occupied by the music. Therefore, ultra snapshot is not available.

7.117 Why is music played by two music apps at the same time after I pressed the headset button? After you enable Smart headset control, if you use multiple music apps to play music, the headset button controls the music app that is the first to be started. To prevent two music apps from running simultaneously, touch Recent and select the music app you want to close from the background app list.

August 2015 174 INTERNAL

7.118 Why can't my phone play flash videos? Adobe Flash Player is not supported. So if the video file is in flash format, the browser can't parse it. It is recommended that you download a third-party browser to watch flash videos.

7.129 All-focus mode 7.129.1 Why is the focusing slow when I take photos in all-focus mode? When you use the rear camera to take photos in all-focus mode, your phone takes a photo at each focal length to enable you to change the focus position by touching the photo. 7.129.2 How do I take photos in all-focus mode? In all-focus mode, you can take a photo first and then select the focus of the photo. Open the viewfinder, switch to all-focus mode, move your phone close to the object steadily and slowly, touch the viewfinder to focus, and then touch the shooting button to take a photo.

7.131 Why can't I turn flash on in digital zoom mode? When you are shooting a photo at twice the normal zoom rate, your phone will shoot multiple photos consecutively for subsequent algorithm processing. The shooting takes a relatively long time. Because the flash is an instant blinking light source and can't remain on for a long time, it is disabled when the shooting object is zoomed in to twice the normal zoom rate.

8.10 Why is the image attached to the multimedia message I sent to another phone unclear? Attachments to a multimedia message can't exceed 300 KB. If an image is too large, it will be automatically compressed before being attached to the message, as a result of which, the image resolution will decrease. To send a large image, use WeChat or Email instead.

8.11 Why does my phone prompt twice for a new incoming SMS? If a third-party application (such as the address book) is installed on your phone, the default messaging app and third-party messaging app will prompt new SMS reception at the same time.

August 2015 188 INTERNAL

8.15 Why is the messaging app displayed as Stopped or not the default messaging app? The default messaging app is a new feature of the Android 4.4 system. After you have installed a third-party messaging app on your phone and set it as the default messaging app, the pre-installed messaging app is stopped because only one messaging app can be used. Only the default messaging app can be used to send SMSs. When this problem occurs, go to Settings > All > Manage apps > Default app settings > Messaging and set a messaging app as the default messaging app.

8.16 Why can't I receive some SMSs? Check whether a third-party messaging app is set as the default messaging app and the junk message blocking function of the application is enabled.

9 Calls and contacts

9.1 When the screen is locked, why is just saying "Contacts" not often successful? This function is not presently supported. This will be improved in subsequent version upgrades.

9.2 When the screen is locked, why does calling contacts with English in their names always fail? This function is not presently supported. This will be improved in subsequent version upgrades.

9.3 What do I if a dialogue box appears saying, Voicemail number missing when I make calls? Do the following to solve this problem: in Call settings>Voicemail>Voicemailsettings > Voicemail number, enter your voicemail number. When you activate voicemail service at a service center, the customer service representative will give you your number. If you forget it, you can call your mobile phone service carrier's customer service number and ask for your voicemail number.

9.4 Why doesn't the dialer connect to phone numbers in my call log? In domestic versions the dialer only supports searching the call log. In international versions the dialer only supports matching numbers to saved contacts.

August 2015 203 INTERNAL

9.5 What do I do if I frequently miss phone calls? 1. Check if Do not disturb is turned on in Settings > All > Privacy & Security. If so, try turning this mode off. 2. Turn of the volume on your phone to its loudest setting. 3. Check whether the phone's status has been set to mute for a long time. Also, check whether being in a noisy environment is causing you to miss phone calls. 4. Restore to factory settings. 5. Update to the newest software version.

9.6 What do I do if my phone doesn't respond when there is an incoming call? If this problem occurs when 4G is enabled, try disabling 4G. Since the 4G network is still being perfected, support for voice calls is not perfect. (Normally the inability to receive calls on 4G networks is caused by coordination problems between 3G/2G and 4G core networks.) So, it may happen that you can't receive calls in some areas when you have the 4G switch turned on. If this happens a lot, please contact the operator of that network to resolve the problem. Temporary solution: When you don't need to use 4G service, try to keep the 4G switch turned off.

9.7 What do I do if I hear static or sounds like "zzzzz" from electrical interference when I make calls? 1. When the problem appears, if the sounds are choppy and interrupted, it is probably electrical interference. Solve this in the following ways: For network problems, this relates to the strength or weakness of your mobile network signal. Try moving to a location with a stronger signal and making a call. First, turn off the 4G network switch and try again to see if there is any improvement. If there is improvement, this may indicate that the present 4G network is a newly established network and is still in a state of instability. 2. When the problem appears, if there is a loud "zzzz" sound in the receiver, then the problem doesn't relate to the network environment. It may be caused by the following reasons: Some people's voices are comparatively loud and some people's ears are especially sensitive to loud frequencies. When calling this sort of person, some people may hear a slight "zzzz". This sound will be even more apparent to people whose ears are comparatively sensitive. If you feel uncomfortable when listening, please lower the volume to a suitable level, like volume level 1-2. This may completely resolve the problem. When you lower the volume, if the volume is too low, try adjusting the position of the receiver to your ear so it is aligned with your ear. If you need to use your phone when spending long periods of time in locations where the volume is loud (for example in noisy environments), try using a headset or Bluetooth headset to make calls.

August 2015 204 INTERNAL

9.8 What do I do if, in the middle of a call, the call is dropped and my phone enters airplane mode? Presently, airplane mode may be activated in 2 main ways: 1. Activated through the shortcut in the status bar. 2. Activated through the menu which appears after you press and hold the power button. It may be that some users hold their phones in a particular way which keeps the proximity sensor from touching their ear so that when they make calls the screen doesn't turn off. This may send false signals to the airplane mode switch on the status bar. Try adjusting the position of the airplane mode among the status bar switches. For example, move it to the last switch in the list. To move it, touch the last icon in the status bar switch screen to access the interface to customize shortcut switches.

9.9 What do I do if I can't receive calls because the other party hears that my phone is currently in a call or busy? This is normally due to network anomalies and has nothing to do with the phone. If this happens frequently, please contact your carrier for advice.

9.10 Why can't I receive calls when 4G is enabled? Is just turning off 4G enough? First make sure that the 4G switch is on. Since the 4G network is still being perfected, support for voice calls is not perfect. (Normally the inability to receive calls on 4G networks is caused by coordination problems between 3G/2G and 4G core networks.) So, it may happen that you can't receive calls in some areas when you have the 4G switch turned on. If this happens a lot, please contact the operator of that network to resolve the problem. Temporary solution: When you don't need to use 4G service, try to keep the 4G switch turned off.

9.11 When receiving a call, why does pressing the power button stop the incoming call from ringing? This a normal event, designed for usability so you can quickly turn off the ring from an incoming call and prevent it from being an annoyance.

August 2015 205 INTERNAL

9.12 Why can't I answer or reject phone calls? According to general conventions, swiping right receives calls and swiping left rejects calls. In contrast, to receive calls on Huawei phones, please touch the middle button and swipe toward the green icon (the receive call icon). This method of operation is unique to Huawei phones.

9.13 Why don't fields without letters in the initial position appear when I search for contact addresses? Apart from fields for names, the contact search function doesn't presently support searching of fields unless they have letters in the initial position of the field.

9.14 When I import contacts, why does the number of contacts decrease? During the process of importing contacts from vCards or from SIM cards, phones use contact names and other information to determine whether a contact is a duplicate. If it is a duplicate, it will be merged into to one contact to be shown in the contact list.

9.15 Why are some calls merged and some calls recorded on separate lines in the call log after merging two instances of the same contact? Check whether the contact has several phone numbers. If it has a "Mobile phone number" and a "Home phone number", the call logs for the same numbers called in succession will be merged. The call log for numbers which are not the same will not be merged.

9.16 Why doesn't my call log merge? The call log merges according to the following rule: when ingoing or outgoing calls made in succession from the same phone number from the same contact are imported or exported, they will be merged into one line of the call log. If calls from other numbers are inserted into the log, the calls from the same number will be separated onto different lines. The benefit of this is that the calls can be arranged chronologically and shown visually. For example: A called 5 times in succession. B then called 1 time. Finally, A called 1 time more. The call record will show the calls the following order. A B A (The first 5 calls from A are merged together).

August 2015 206 INTERNAL

9.17 Why doesn't my phone display the contact photo for incoming calls even after I have set the contact photo? Check whether the same number is saved in multiple contacts. When the phone matches a number with a contact, it selects the contact for whom the number is saved first.

Storage and file management

10.1 What do I do if the internal storage is full and an error message appears when applications are opened? The Android operating system for mobile phones is installed on the system partition of the phone's internal storage. When a phone doesn't have sufficient RAM available, the operating system will allocate some storage space outside the system partition to be used as swap space. This allows data to be freely moved in and out between the RAM and swap space. If your phone's internal storage is full, the swap space may not be large enough to allow the data to move in and out. In this situation, processes using large amounts of RAM may encounter errors. To resolve this problem, delete some content from the phone's internal storage and restart the phone.

12 Location service and navigation

12.1 Why can't the GPS of my phone search for a satellite?

 Make sure you are not in an enclosed area (for example, a room on the first floor of a tall building, a small area surrounded by tall buildings, or an underground garage) because tall buildings block the satellite signals. Bring your phone to an outdoor area and enable the data service to help quickly receive GPS signals. Do not touch the upper right corner of your phone where the GPS antenna is installed.  Make sure your phone's protective cover is made of plastics or leather instead of metal, because the metallic protective cover blocks your phone's antenna signals.

12.2 Why can't a third-party application map load the map data? 1. Ensure that the network connection is normal, because a slow network speed results in data loading failure. 2. Remove your microSD card. Your phone is running the Android 4.4 or advanced versions and the third-party map application may not have the write right to your microSD card, so this application can't load map data to your microSD card.

12.3 Why can't the installed third-party positioning application locate correctly? The location information of a third-party positioning application is provided by the third-party application provider if there is no GPS signal available, resulting in incorrect positioning results. Use another application and try again. You can also take your phone to an open area and try again.

August 2015 234 INTERNAL

12.4 Why does the GPS icon occasionally appear on the status bar? Some applications using the location information may use the GPS function when they are enabled or periodically updated (for example, a weather application). Go to Settings > Location access > Access my location. Check whether the corresponding applications access the location information.

12.5 Why is the compress inaccurate? The compress may not be calibrated. Open a compass application (map or compress) and move your phone in an 8-pattern.

12.6 Is the GPS function charged? The GPS function doesn't require the mobile network. Therefore, it is not charged. The GPS positioning with a mobile or Wi-Fi network on can be more accurate. However, Internet access is required when you browse a map or plan a route using GPS software, which may incur data usage fee. It is recommended that you download an offline map package.

12.7 What can I do when the GPS software locates slowly or fails to locate?

 Check whether your GPS signal is poor indoors, which may result in slow positioning or positioning failure. Locate in an open area where the network signal strength is strong.  Check whether your phone is connected to a Wi-Fi or mobile network because some GPS software requires network connection.  If the foregoing methods fail, contact Huawei technical support or use other GPS software.  If the problem persists, contact Huawei technical support or take your phone to an authorized Huawei service center.

12.8 What can I do if the GPS positioning is inaccurate?

 Locate in an open area where the network signal strength is strong, for example, on city streets or in squares because the GPS positioning accuracy depends on the accuracy of the GPS and map. Try not locating indoors.  Connect to a Wi-Fi or mobile network or use the A-GPS while enabling the GPS function.  If the foregoing methods fail, use other GPS software.

August 2015 235 INTERNAL

Therefore, mobile users or others are provided with location based services, such as weather, GPS, and shopping.

12.13 How do I enable the LBS? Go to Settings > Location access and enable Access my location. Enable GPS.

The figures are for your reference only. The actual screens may vary.

12.14 Does the LBS use the data traffic? Generally speaking, after you enable the LBS, your phone will load map data using the data traffic when running the location based app. It is recommended that you download an offline map and regularly update it using a Wi-Fi network before using the map software. Therefore, the LBS may minimize the data traffic usage.

12.15 What can I do when the LBS is unavailable? 1. Make sure that the mobile network is enabled and check whether the Wi-Fi network is available. 2. Go to Settings > Location access and check whether the Wi-Fi is enabled. Enable the Wi-Fi network connection function. 3. If the problem persists, restart your phone and try again.

August 2015 237 INTERNAL

12.16 What can I do when the LBS fails? 1. Go to Settings > Location access, check and enable LBS-related options. 2. Make sure that the mobile or Wi-Fi network connection is normal, because data from the server can't be acquired when the network is unavailable. 3. Use your phone outdoors and try again, because reception of the GPS signals will be affected underground and indoors. 4. If the problem persists, restart your phone and try again.

12.17 What is GPS? The GPS stands for Global Positioning System that uses the satellites for positioning and navigation globally.

12.18 Does the GPS use huge data traffic? It depends. The GPS doesn't use the data traffic itself. However, the data traffic is necessary when your phone loads real-time information or map data. The data traffic volume depends on the loaded information during GPS. Different GPS software uses different data traffic. Some malicious software may use huge data traffic. It is recommended that you download standard GPS software fromPlayStore.

12.19 How can I reduce the data traffic usage fee when using GPS on my phone?

 Use standard GPS software.  Download an offline map before using the GPS.  Close the GPS software on time after using the GPS.

12.20 What can I do if the GPS information is inaccurate? Generally, the information of a civil GPS is accurate within 10 meters. However, the GPS receiver may receive deviated signals that are blocked by trees and clouds. To improve the positioning accuracy of your phone, try the following methods:

 Update the GPS software and map to acquire the latest traffic information.  Go to Settings > Location access > Location mode and select High accuracy.

August 2015 238 INTERNAL

12.21 How can I strengthen the GPS signals?

 Try using the GPS function in an open area to ensure normal signal transmission.  When you use the GPS function in a car, place your phone near the front window of the car.

12.22 What is the working principle of GPS? The phone sends its location information (latitude and longitude coordinates) to the positioning background through the self-attached GPS module. Then, the positioning background calculates the coordinates on the electronic map and marks the positioned object on the map, which shows the current geographical location of the phone.

12.23 What are the differences between GPS and base station positioning? For GPS, the phone sends its location information to the positioning background through the self-attached GPS module, and the positioning background performs positioning. For base station positioning, the base station of the telecommunications carrier determines the phone's location by calculation the distance between the base station and the phone. GPS uses the satellite for positioning, which consumes more power but is more accurate. GPS doesn't work when the phone is placed indoors. Base station positioning is less accurate, but it works indoors.
