So I noticed the other day while playing Words With Friends that I couldn't move the two left tiles onto the board, and today noticed that when I try to tap on the "7" in the dialer, it does not register. Basically, the lower left hand corner of my touch screen no longer functions. Anyone else having this problem? If so, any ideas for a fix? I'm up for a new phone in August, so ideally I can hang on with this thing for a couple more months.
