Hi there. My initial request was basen on the personal experience backed up by similar reports by various forums' users.
I saw screen with not working area - roughly 1 centimeter from the bottom. Twice. I also saw screen where touching is shifted with few centimeters up, or down. I am not saying its a hardware problem. It could be software one, in which cases the touchscreen calibration COULD help, no?
