after replacing proximity sensor, screen activates randomly.
i followed the guide: Installing iPhone 4 Power & Sensor Cable to replace the flex cable, as my power button did not work at all (btw, seemed that the problem was not the flex itself, but the screws that holded the button, they needed to be unfasten a little, ot it will not work)
anyhow, now the button works perfectly, but the screen looks like it's not calibrated, I click in one area, and itt activates other.
seems I messed up something when I replaced the flex cable, but I do not understand what, as if I broke the digitalizer flex, it should not work at all....
anyhow, any tips?
edit: I used a finger-draw program to see sscreen behaviour and seems that detection on some orizontal areas is missing:
(I can not "paint" in two horizontal bars at the top, looks like it's not registering my strokes)
similar to this, where XXXXX marks the area I can not paint:
Is this a good question?
