How to solve the problem of screen flashing on OPPO phones

If only a certain interface flashes, it may be caused by slow interface refresh when operating this function. It is recommended to observe it first.

If the call interface flickers during a call, it is because the light sensor is touched, which is normal.

Check whether automatic adjustment of screen brightness is turned on. The screen brightness will be automatically adjusted according to the external environment of the phone. You can first enter the phone settings - display - turn off automatic screen brightness adjustment and then observe.

Have you enabled certain contents of the developer options, such as turning on switches such as GPU view update? It is recommended to go to the phone settings--More--Developer options to turn them off, and then restart the phone to restore.

If the screen flashes frequently when operating third-party software, it is recommended to uninstall the program or enter the recently installed software to rule out whether the downloaded software is incompatible with the phone.

Back up important data (contacts, multimedia files, etc.), then restore factory settings (Settings - System "More" - Restore factory settings, do not check "Completely clear").

If the problem persists, please go to the nearest customer service center for inspection.
