Not dropped, not got damp. Been working fine. This morning I was using as normal, then when I next picked the phone up it was playing up.
Essentially whats happening it the top cm of screen, the left 90% "touches" / "clicks on" the left 20%, and the remaining 10% of screen which is very small "touches" / "clicks on" the other 80%... in other words is compressed.
I've restarted the phone, and I guess the next step is factory reset, but I don't want to do this just yet.
Just wondering if chances are that a software issue has caused this, or whether the digitiser which has not been abused at all could have simply packed up for no apparent reason?
