11.2 Why can I see some horizontal lines under lights
when the screen is turned off?
This is a normal phenomenon, which is caused by the circuit transparency of the touchscreen
functions.
11.3 Why doesn't the touchscreen respond when I slide the
screen to unlock?
This problem may be caused when you receive an incoming call with your phone in your
pocket. If this problem is caused by misoperations on the touchscreen, press the power button
to lock the screen. Then, the screen resumes after it turns on. If this problem occurs during
charging, check whether you use a standard charger.

Check whether this problem occurs only when you use a certain app or certain apps. If
yes, this problem is not caused by your phone. There are various apps in the app market.
Certain apps occupy more phone resources and therefore cause certain problems. Certain
apps may contain viruses that consume more service charges or traffic. You are
suggested to download apps from Huawei App Center.
If the problem persists after you uninstall the related apps, back up the data in your
phone and restore the factory settings.
If the screen does not automatically turn on after you end a call, press the power button
to turn on the screen. Check whether the light sensor on the upper part of the screen is
blocked. When you place the phone near your face, the sensor detects the blocking and
the phone turns off the screen, to avoid call release by misoperations. If the sensor is
blocked, your phone does not automatically turn on the screen after you end the call.
Check whether the Strict Mode enabled option in Developer options is enabled. This
option causes a red rectangle to border the screen. Therefore, disable the Developer
options when you normally use the phone.
Check whether you have received the system update notification in Updater. Connect to
the Wi-Fi network and download the latest system version. Then, update your system.
