My tablet (Asus TF300T) has been starting to show sensitivity issues. It repeatedly shows touch moves that aren't there, such as these: (this screenshot was taken using the debugging option for showing touch input)
It started out with an occasional movement that was already annoying, but it went worse: these dozen concurrent presses are persisting, moving and raising in amount: The tablet is uncontrollable now. Is there a way to turn down the sensitivity so that these fake fingers don't show up or to turn the touchscreen off completely?
Although the tablet itself isn't accessible anymore, USB debugging is turned on, the tablet is not rooted. Standard Rom, updated to 4.2.
