Take the Xiaomi Mi 10 mobile phone MIUI12 system as an example, when using the mobile phone to play games, the mobile phone frequently goes black, first of all, the user can see if the mobile phone can be automatically restored after the black screen, if so, you can clean up the background running applications on the mobile phone, or turn off the mobile phone and restart it, which can generally solve the problem.
If it can't be automatically restored, users can press and hold the power button of the phone to force the phone to restart, and there is generally no problem after the phone is restarted.
