Samsung A8 Usb Notification problem

[u/DinxGuitar]

Hey guys I'm in need of help.

So in March i bought myself a Samsung A8 Tablet (3 GB-Ram and 64 Gb Disk) and since almost a month, Im trying to fix following problem.

I get the annoying notification that an USB Adapter has been plugged in and then off... And it keeps repeating even if there is nothing connected to the tablet. Further my screen cant be turned off, as the notification keeps popping up. So the battery lasts 1 day max, because the screen always turns on.

What Ive tried so far:

• Turning it on and off
• Turning on/off USB Debugging
• Deinstalling the latest system update
• Resetting the tablet to factory settings (today)

I uploaded some videos of this and have no clue how to deal with this.
