I had the same problem. It started out with the top of the screen not responding to touch then gradually worked its way down until it was less than half the screen that would still respond to touch. I imagine the entire screen would have eventually gone but one day I had it on the charger and it must have went to fall off the bed but since the cord wasn't long enuf to reach the floor (it was coming from over the headboard) I found it just hanging on the charger beside the mattress and when I looked at it the screen had broke which of course made it where none of the screen worked! The best advice I have concerning this tablet is: if you're still within the time limit to return it to the store, DO IT because it's not a matter of will it end up having problems, it's how many problems is it going to have before it finally renders useless! This is only one of the MANY issues I had with this tablet the entire 3 mts that it was useable.
