I don't think that is right. After I replaced a broken Nexus 4 screen, it would only register touches if you held another finger somewhere on the screen, and after rebooting, would only register if TWO other fingers were held on the screen! Only resetting the phone completely fixed the problem, so I think something about the reset process must run a calibration of some kind.
Now the problem has surfaced again and I would like to know how to calibrate without resetting everything.
