My son thought it would be fun to have this prank app on his phone. Well it has frozen the screen forever kind. Tapping the right corner, pushing the camera button, holding down the home key, taking the phone apart does nothing. How do we get that prank app off his phone (it's a Motorola Droid) and get his phone back and yes the battery is full. It seems to have life when in the docking station but when it is taken out the screen goes back to the prank one.
