Of course this only happens intermittently.
Possibly related to low charge state.
Android ver 9.
Not relevant I expect but I have an encrypted SD card.
The problem cropped up about 3 days ago.
I left the tab on charge till fully charged (normal display restored) then restarted in Safe Mode.
Uninstalled all games and potentially problematic apps.
Then restarted in normal mode & all seemed OK.
But the glitch "threatened" to recur this morning.
(A vertical separation seemed to appear when in Google Chrome. I used the power button (the fingerprint reader button beside volume button) to back out & the problem "went away".
I expect that it will recur.
Any ideas as to whether it is a hardware problem?
Or Google Chrome using too much resources?
Any advice very much appreciated.
I'm running a NetFlix movie now & all seems OK.
I picked up a tip that disabling auto screen brightness may help so did that.
Again, any advice welcome..
