Have a problem with what might be ghost touches on the touch screen.
When playing fullscreen movies it sometimes randomly pauses and / or resumes as if someone touched the screen (or pressed space). Not always, just sometimes. I have found no pattern. Not tied to a specific application as far as I can tell.
Also, once the display went bananas with crazy ghost touches everywhere all over the screen when i switched to tablet mode. The keyboard had stopped working as well, and I was forced to reboot for it to stop clicking everywhere.
