I don't know if anyone else noticed this, but touch screen is far less sensitive in Sailfish than in Harmattan if not grounded either via the charger or by touching the plate on the back of the N9. (this also applies to UbiBoot and NitDroid)

I know that N9's touch screen isn't the best at all, but at least it stays usable in Harmattan even when it is not grounded correctly.

Is there any chance that this problem can be solved with some clever coding, or is the source of this problem too complex to solve it?
