anybody know wat is wrong with HTC legend screen?

The notification screen cant be pulled down.. Sometimes the touchscreen wont respond to any touches..Cannot even pull down to unlock. When sms, the QWERTY keypad types itself sometimes or doesnt responds at all.

Could it be digitizer prob? Both my wife's & mine HTC Legend facing same issue....

Able to claim warranty? Or is it just a common issue in all HTC Legend....only a matter of time...


Feedbacks thx
