My concern is that is there a third party app that can calibrate our Z1 touch screen? Much like with xperia tipo, I have stumbled upon that thread and tried installing the TouchFW apk something like that but failed to do so since my phone says app not installed.
Most people with xperia Tipo have the same problem the same as the z1 touch screen problem that fails to register touch and with that screen calibration app their problem was solved.
I really hope that people here might have a solution for this one since it can really help a lot of z1 owners out there.
Thank you very much.
