Hi,
My E680i (flashed from E680) has a this problem, I can solve it.
I can tap exactly on any position on screen. If I want to tap on one position, I have to tap over that position about 1mm.
The "Screen Calibration" function don't work. I ONLY can tap on target in WN and SE conner, when I tap on center screen, it not reponse.
All of other functions work properly!

Please help me to fix this problem.

Thanks in advanced!

Motorola Service Centre, I'm afraid, is the answer.
