Anything that'll let me tweak the touch location on a capacitive screen?

[IronMew]

I have a cheapo tablet whose touchscreen always registers my touches about 2-3mm lower than where I actually touch. I sort of get used to it after a while, but it's still annoying, as it's not the only touchscreen device I have and I need to rewire my brain every time I switch to the others.

Is there an app that'll fix this? I don't need a full recalibration, I just want something that'll tell the system to behave as if I was touching 3mm above (though I'll do a full recalibration if such a thing is possible and would fix the issue).

Bump. Still having this problem.

I've seen that as well with cheapo tablets and phones. Most likely due to poor assembly and workmanship, because the digitizer layer is out of registration with the screen. Unfortunately with capacitive multi-touch devices, there doesn't seem to be a way of calibrating them. If they were assembled correctly, should be no need to calibrate them. With the Apple iPad, the digitizer is firmly bonded to the screen layer, it's a sealed unit, so there is no way that it could be out of registration.

The older pressure sensitive resistive touch-screen devices, like Windows CE, would require you to go through a calibration step to ensure good registration. And so they always had touch-screen calibration built-in.

I don't think there is. You'll probably have send it back as a quality problem and poor workmanship, or just live with it.

If you are rooted, you could try Touchscreen Tune. It's only designed for a few specific devices (and yours is undoubtedly not one of them), but it might be worth sideloading the free version and see if it works for you.
