I have bought a generic touchscreen replacement (not the actual screen where pixels are drawn, but rather the touch sensor where touches are captured) for my Defy/MB525, and replaced it myself.
It doesn't work, it seems to register many random touches in a few seconds (while the charger is disconnected, and no screen protection films are present). I know I probably either did something wrong or got a malfunctioning touchscreen, but maybe I'm missing something?
Do I need to perform some calibration? If so, how can I proceed? My phone is asking for a locking code and I can't enter it as it is.
