I experienced exactly the same what other people have already reported: The tablet has been fully charged, and then it freezes (crashes). A soft (!) reset (on/off + volume down) is always necessary.
Seems to be an issue of the OneUI 8 update. Please don't answer with predefined text patterns a la 'clear app caches' etc. as all those hints do not work.
Here are several references with this severe bug. Everybody with a A9 or A9+ tablet experienced the same and nobody found a solution so far:
Yeah it happens to me too, but sometimes, not always, I hope Samsung fix this bug soon. Never happened before One UI 8 so it's probably a software bug,
I have the same issue since the same update of the OneUI 8 and the problem is still not resolved. Every time I charge(up to 80%) I try to unlock the screen, it turns on and after touching it to unlock with the pattern, it goes off and become not responding. So I make soft reset with the side buttons every time since then.
Thank you for your feedback so far. It would be great if you could write to the Samsung Support via the Members app (feedback button). Please reference to this thread. URL of this thread see below.
Please, don't make any hard reset, and don't ship your device to the Samsung repair center. This is not a hardware issue, it is a software issue of OneUI 8.
Samsung has to know about this to fix it. Tell them that there are several people with exactly the same problem. You should include the system report, too (hook at the feedback dialogue).
The only solution i found so far is to completely turn off the tablet so the Android OS is not running while the tablet charges. After you charge it, you can turn it on. Just don't leave it charging while the tablet is on or unplug it before the charging is complete.
