Today after playing Backgammon for about 15 minutes all of a sudden the game began to 'select' a piece to move and move it without me touching the screen. If I did an UNDO (to undo the move move) it would repeat the same action once again without me touching the screen.
I tried to turn the tablet off but could not.
I then exited to the Home screen and an app on the home screen automatically started up as if I had tapped on the icon.
I unattached the keyboard in an effort to stop this wild behaviour and shut the tablet down. I was eventually able to stop the tablet holding down the start/stop button.
The tablet has NEVER been dropped and is only 4 weeks old.
I could not find a post for this condition doing a search of erratic screen behaviour.
