8800 with random keypresses
 

Have a user who has an 8800 (4.2.1....). When he comes back to the device, it is on the "Type 'blackberry' to continue" screen, as if the device is typing away at the password by itself.
Tried resetting device by removing battery, after booting up, I am unable to unlock it as the characters start appearing in the password box by themselves, no keypresses from me.

Anybody hear of this before.
He had a similar issue last week and we exchanged the device for him, still same problem

thats weird
