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.

Same here. Device almost new. Screen timeout 30 min.
Randomly locks. Takes 10 or more tries to wake, unlock.
Battery over 50 percent.
I suspect a firmware glitch or hardware fault.

I have the same problem too. Screen timeout 30 minutes, battery over 50, but still it randomly locks and takes 10+ tries to wake. Super bizarre and annoying.
I've had this tablet for over a year, but this problem only started happening this summer (June 2022). Was it a software update?
