The screen stays dark after I end a call
When you hold your device to your ear during a conversation, the screen is turned off to
prevent you from unintentionally activating the touchscreen. If you experience that the screen
is not turned back on when you move the device away from your ear, try the following:
As a temporary solution press the power key lightly. If the screen isn’t turned back on press
the power key again.
Make sure that you have removed the temporary protection film that covered the screen
when you first bought your device. The film is only designed to protect the screen during
shipping and is easy to peel off.
If you have applied a screen protection film on your device, make sure that it is specifically
intended for your model. It is important that the screen protection film has holes that are
accurately placed so that the proximity sensor is not blocked. To verify the exact location of
the proximity sensor for your model, refer to the overview illustration in the User guide.
Turn off your device and then turn it back on. By doing this you turn off all running
applications and free up memory, which sometimes automatically solves the issue.
Update your device to ensure that you have optimal performance and the latest
enhancements.
Perform a factory data reset. This is sometimes the best solution if your device stops
functioning properly, but note that it will delete all personal content saved on the internal
memory of your device. Make sure to back up data that you want to keep.
To back up your data using a computer
1.
Connect your device to the computer using a USB Type-
C™ cable.
2.
Make sure that the USB connection mode on your device is set to Transfer files.
3.
Transfer/Save your important data in PC.
4.
Advisable to Sync your data in google account.
