I am running CyanogenMod 7 on my phone. About a week ago, my phone started doing weird stuff. First, I can barely slide the unlock slider because it seems like part of my touch screen doesn't work. Furthermore, when I do manage to unlock it, the "E", "S", and "Z" keys don't work on my keyboard. I have no clue how to fix this! If you have any idea as to what's going on, PLEASE let me know.
