Since a couple of days ago the screen calibration is incorrect (n810). The calibration of the right-hand side of the screen is off by about 0.5cm. For example, clicking on an application's close icon will activate the battery status.

I have tried the screen calibration utility (a number of times) but on the second target (top right) even though I tap directly in the centre of the circle it tells me to tap closer to the target.

I have re-flashed the tablet, thinking this may solve the issue - but the fault remains.

I have noticed on some other posts with similar problems it has been put down to using a screen protector (which I don't use) or possible high humidity, but living in the UK I don't think this is a problem!

To me, it looks like a hardware fault. Any ideas if I'm possibly correct?

Thanks.
