Ok, I read a few posts, and some suggested to wipe the phone. I did. I formatted the Memory card, I am keeping it plugged in. out of nowhere the screen just stops becoming non responsive. I have to pull the battery out numerous times before it works. Sometimes if I open the keyboard and close it, it works, but really this is getting annoying. Does anyone know what may have caused this? I haven't dropped it, and no water damage, no clue what to do.
