Hi I have a 2020 Galaxy Tab A7 and the screen keeps locking randomly. It can be instantly after unlocking the device or from a few seconds up to a few minutes after unlock. This happens whether I am touching the screen or not. It is not powering off, it's just locking the screen but makes the device unusable.
I've tried the following to resolve it but nothing has made any difference.
Removed case in case magnet affecting it.
Software is the most current version.
Screen time out function increased to max.
Opened in safe mode.
It's not worth paying for a repair but I would like to attempt a repair myself before replacing.
Any suggestions gratefully received.
I have the same a video will play,but can't pause it,have to push power button and swipe to open it and fine for a while, but goes again have tried loads, cache removal etc help
