Is this a good question?

You can try a soft reboot (no data loss) press power and volume down buttonus simultaneously hold them until you see the tablet restart. Ignore the screen until you see the startup screen, release the buttons also check in settings and see if it is still showing available update.


Mine just started having this same issue but this was both before and after the android 12 update. Updating didn't break it or fix it, for me at least, it appears.

For me, if I flip my new Anker cable around "upside down" it will work. If I put it Anker logo up, it disconnects/reconnects 3 times a second if connected to my Anker power bank.

My Anker super fast charger and it's different cable are the same way, but opposite cable direction.

Moral of the story, all of our cables decided to break at the same time, obviously.

No, it appears Samsung actually just broke all of our tablets at once. Thank you, Samsung. I don't think yours is physically damaged.

I replaced now the USB charge unit and the battery. Both replacements don't solve the problem. For this case the temperatur sensor or the measurement device is placed on the mainboard. I hope this info helps other people on this webside.
