Got this problem too.
Tried to do software repair, then downgrade to b.10 from .54, then flashed android 2.3.7 - and nothing changes. Pretty sure it`s a hardware issue.
In my situation every 5-7 touch have been lost, and + additional non-workable region of a screen.
So, I went my phone to warranty service, will see what it would be...
Mine is a peculiar case.
The touch seems to be working fine for normal use i.e. opening apps and menus (as these operations dont normally require speed) but while typing, i have to touch 2-3 times. Basically, it is not as sensitive as before and this thing happened suddenly before 2 days. its very irritating specially while typing.
I have to touch and hold for a while only then it accepts the input. Is there anyone who is getting such problem?
Same of us !!! Go to near service center as soon as possible and :
