I just got a droid 2 global through verizon a few days ago. I'm having issues with the screen after the device has been locked for a while.
For example, I will lock the screen and leave it setting on my desk for a while. Then when I go to use it I am able to unlock the screen, but from there it acts a little strange. None of the bottom buttons (Home, Back, Menu, etc) will work. The main portion of the touch screen starts pulling down the notification bar about a half inch and releasing it. The whole time this is occuring, the default vibration for when you click the touch screen is going crazy like the screen is being tapped rapidly even though it's not being touched. I can get it to stop vibrating by re-locking it, but when unlocked again the same problem occurs. I eventually had to do a soft reset.
Yes they put app killer on my phone, but this seems to be more of a hardware issue to me. Any advice?
