The problem is that many times the digitizer becomes damaged along the outer edge, so by setting false coordinates, you can fool the system into thinking it has been calibrated. You can easily edit the registry and enter the correct values normally, but it still won't work as touching the digitizer will send an erroneous electronic signal...
Hello. Simpad I have a SL4, but I stylus on it. Touch screen does not work with if pressed by hand or other sharp object? Touch screen stylus only works if you? Thank you.
