Reason: When used in a darkly lit place, the brightness of the screen will automatically dim, which may cause the screen to jump and flicker.

Method: [Settings] - Display - Brightness - Remove the check of [Auto Brightness].

Reason: There is an item [background color] in the battery saving mode option, and if this option is turned on, it will also cause the screen to flicker.

Method: [Settings] - Power Saving Mode].

Why: The two options are interpreted by the system as follows: display screen update (flashing the screen when updating) and strict mode (make the screen flash when the program is performing a long operation on the main thread).

Method: [Settings] - Developer Options] - Remove the checks of [Display Screen Update] and [Strict Mode].

Reasons caused by third-party lock screen software: It is found on the Internet that a small number of people have installed third-party lock screen software or themes that cause splash screens, and some are caused by incompatibility with the system.

Method: Uninstall the third-party lock software or third-party theme.

Reason: Some of them appear to be flashing when surfing the Internet, such as turning on [mobile data] and [wifi], after analysis, it is believed that it should be a problem of poor network signal, but there are also places that cannot be explained.

If none of the above methods can be solved, then you can only re-flash the system, which is the best solution, and it should not be after flashing.

Is it flashing as soon as the traffic is turned on? If you don't turn it on, don't flash it, and don't flash it when you use wifi?

In fact, it is the Hall sensor that is out of order because of the magnetic field generated by the traffic generated when surfing the Internet.

Hall Sensor: Automatically recognizes when the (adapted) case is on or off. Typical application: Samsung S View Cover case.

May I ask if you have fixed it, mine also doesn't know what to do.

Settings - Developer Options - Display screen update, there should be that setting, just don't tick it.

Cover the Hall element in the phone with tin foil to solve the problem.
