Your phone comes with a 5 V 2 A charger as standard, and it also supports 9 V 2 A high voltage quick chargers. When your battery is low and you charge your phone for 10 minutes, you can extend your talk time by around 2 hours. The specific length of time is dependent on the network environment. Please make sure that you buy an official Huawei 9 V 2 A charger; unofficial quick chargers will not work properly. If you need a quick charger, you can buy one from Huawei Vmall or official Huawei experience shops. 1.2 Does my phone support reverse charging? Yes. Your phone supports charging other phones using reverse charging, but you must use a Type-C OTG cable. Your phone supports reverse charging Huawei noise cancelling headsets. 1.3 Why doesn't my phone come with a quick charger? Your phone comes with a 5 V 2 A charger, which is compact and highly portable. When the screen is turned off, you can fully charge your phone in around 2 hours, which is sufficient for most users. Your phone also supports 9 V 2 A quick chargers. You can buy an officially designated charger on Huawei Vmall or from a Huawei experience shop. 1.4 Why does my phone display the "installation failed" message when I install certain apps in guest mode? Reason: This may be because another user has already installed the app, and the version that has already been installed is newer than the version you are trying to install. Solution: It is recommended that you switch to owner mode, enter Settings > Apps, find the app, touch it to enter settings management, touch the menu at the bottom of the screen then select the "uninstall for all users" option, and then download and install the app again for the guest. 1.5 Why are some system functions unusable in guest mode? This is because some system functions do not currently support multiple users or would interfere with the owner, therefore the functions cannot be used.

To protect the owner's privacy, your phone will not allow the guest to send SMS messages. 1.7 Does my phone have a radio function? No. Surveys have shown that people are using radio functions on phones less and less, and more people have switched to using Internet radio, which offers more services. It is recommended that you download an Internet radio app. 1.8 What is multiple antenna selection (MAS)? Virtual antenna technology has overcome the space constraints in using a multi-antenna structure in a phone. The antenna is adjusted automatically according to the user's grip and the signal environment to allow the antenna to perform optimally and further enhance the communication experience. 1.9 Does my phone support Bluetooth 4.0 or 4.2 BLE? Yes, it supports Bluetooth 4.2 BLE, and is backwards compatible with Bluetooth 4.0. Bluetooth 4.2 BLE is Bluetooth Low Energy added to the traditional Bluetooth. It has been applied extensively to wearable devices such as watches, wrist bands, heart rate and blood pressure sensors, and Internet of Things devices. 1.10 Does my phone's Wi-Fi support 5 GHz bands? The Wi-Fi supports 2.4 GHz and 5 GHz bands. Different channels are supported in different countries and regions. Please call Huawei hot line for details 1.11 Does my phone support Bluetooth APT–X? No. Bluetooth supports 3 audio codecs: APT-X, SBC, and AAC. SBC is a commonly used codec. The audio quality is average, and it is used 80% of the time. APT-X is better and has less delay, but it needs to be supported by your phone and your headset, otherwise the SBC codec will be used.

No. 1.13 After switching to data services, there is a little button on the Wi-Fi settings screen. What does it do? When the quality of the Wi-Fi network is poor and your phone switches to using data services, this icon will appear. Touch it and your phone will automatically return to the Wi-Fi connection. 1.14 Does my phone support NFC? Does it support NFC payments? The EVA-L09 outside China supports NFC. Other editions (EVA-AL10, EVA-AL00, P9- CL00. EVA-DL00, EVA-TL00, EVA-L29, and EVA-L19) do not support NFC or NFC payments. Big data research has shown that there are currently relatively few people using it, and XX Pay, which uses NFC for payments, is still in its early phase. It will take some time for it to develop, therefore this service is not available on all phones. In addition, we provide direct access to the Alipay QR code screen using fingerprint unlock when the screen is turned off, which is faster and convenient. 1.15 What is the advantage of the dual rear cameras over a normal camera? The Huawei P9 has a dual parallel camera design. The quality of images and the photo shooting experience have been improved through image processing and recognition. The dual cameras have advantages over traditional single cameras, namely large aperture capture, focus speed, image clarity, and noise control. 1.16 Can I still preview or take photos if one of the rear cameras is covered up? The Huawei P9 features a dual rear camera design. If one of the cameras is covered up, you can still see the photo preview normally, but the image quality of photos you take will be influenced. It is recommended that you check the cameras to avoid affecting your photos. In black and white mode, only the secondary camera is used. If the secondary camera is covered up, you will not be able to take a photo. Issue 01 (2016-03-08) Huawei Confidential 3 Huawei P9 Smartphone Feature FAQs 1.17 What is the difference between laser-assisted focus and dual rear camera focus? How do the two work together? The dual rear cameras measure distance according to the content of the image by calculating the distance between the object and the cameras. This is restricted when there is no texture in the region or in low light conditions. Laser-assisted distance measuring works differently, so it can effectively make up for the deficiencies of using the dual rear cameras to measure the distance in specific scenarios. 1.18 Both the Huawei P9 and Honor 6 Plus have dual rear cameras. What improvements have been made in the dual camera focus and photo capture speed of the P9 compared to the Honor 6 Plus? The Huawei P9 uses an image post-processing algorithm from a dedicated image processing DSP. The wide aperture algorithm and focus algorithm have both been improved, and performance has been more than doubled. 1.19 Why do photos taken using laser-assisted focus have red marks? To bring you the best possible photo taking experience, the Huawei P9 features laser-assisted focus, which improves the photo capture speed at short shooting distances. Laser-assisted focus will be turned off momentarily during photo capture to avoid affecting the shot. When you take a photo, normally there will not be red marks. They will only appear on photos where the laser has already turned off, and the subject is a highly-reflective object (such as a mirror or a marble table). Other current products in the industry that use laser-assisted focus all exhibit this phenomenon. 1.20 Why can't I set the resolution of the camera? The resolution menu is unavailable for certain shooting modes (Super night, Light painting, Time-lapse, Slow-mo, Panorama, and Watermark modes). We provide the best resolution supported by the current mode. You can check the resolution of the current shooting mode in the grayed out menu. Issue 01 (2016-03-08) Huawei Confidential 4 Huawei P9 Smartphone Feature FAQs 1.21 Why does the background not appear blurry when I take photos in wide aperture mode? To produce the blurred effect in wide aperture mode, there needs to be a significant distance between the different parts of the scene.
