Hi all. I've got some foam creeping up inside my screen. Held vertically, it is along the bottom edge of the home screen above the menu, home, etc. buttons. Twice the screen has been stuck perpetually trying to scroll and was unresponsive to my touch. Both times rebooting with the keyboard solved this. It's not terribly bothersome to me; but if I'm going to try to make this thing last another 16 months... Has anyone else seen this?
