Sometimes I'll get a text message and I'll start typing back my reply and I'll look up to see what I've wrote so far and there is nothing on the screen. I can back out of the message and go back in and it still won't work. Go into a different message, still won't work. So I headed over to my task killer (ATK) and killed the messages app and re-opened it. Still nothing. The only remedy is to set the phone down, and wait a couple minutes and it magically works again! This method works, however it is very very annoying. Does anybody have any idea how to fix this?!!! Thanks in advance to anybody who offers any advice.
