What about the black screen of the mobile phone?

There are many reasons why the mobile phone displays a black screen, such as system problems and software conflicts. The damaged screen will be displayed as a black screen, and it is suggested to take the following steps to investigate and deal with it:

Restart the machine.

Press and hold the power button and volume button at the same time for more than 7 seconds, and then try to turn the machine on and off again.

Restart after charging

Connect the charger and see if there is a charging display. If there is a charging prompt, you can charge for a while before restarting.

Uninstall third-party plug-ins.

If you can operate the phone after restarting or charging, please uninstall the third-party plug-in program running before the black screen.

Restore factory settings

Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

Send it for repair

If the problem still exists, please bring the purchase invoice, maintenance card and machine to the service center, and the engineer will check the machine and deal with it.
