Why did the home button and bottom of screen stop working?
A few weeks ago the three buttons (home, back, menu) stopped working out of nowhere. Literally my phone died and when I turned it back on after charging, the buttons no longer worked. I was able to download an app so that I didn't have to worry about it. Now the bottom portion of my screen no longer works. I believe the screen is dying from the bottom up and I don't know why. Please help.
