Galaxy A11 screen will not turn off (when UNplugged)

[FrustratedAtGalaxy]

My screen will not turn off. Ever. Not during a timeout (tried changing times), or after pressing the power button. This is a sudden thing and it's absolutely driving me mad.

If I leave it alone, the screen dims for the timeout, screen goes blank, and them BAM! Start again. If I press the power button, the screen goes blank and them BAM! Bright as hell.

I've done a factory reset and am still experiencing the issue as we speak. The strange thing is, it behaves perfectly normal while plugged in.

I've tried disabling every single service I can in developer tools, I've even turned on the pressure sensor tracker to see if it thinks something is touching it.

Any help at all would be greatly appreciated.

Thanks in advance.

I have the same issue on my Samsung Galaxy A11, and just tried fixing my phone in safe mode. This issue persisted even in safe mode. Each time you press the power button it immediately goes to the lock screen, but if it's plugged in it will turn off normally.

Welcome to Android Central! Do you have a case on? If so, does this happen with the case off as well?

Welcome to AC!
Try cleaning the charger port

Any problems with the hardware buttons? Do any of them seem a bit sticky, or do you notice your volume adjusting itself without you pressing anything?
