Scenario 2: The camera is slow to respond when you take a photo. Cause: In low-light conditions, the camera processes the image to improve the image quality. This may take a few seconds to complete. Too many apps are running in the background, leading to a high CPU usage rate. Solution: Enable Flash and touch the screen to bring the image into focus.
