Answer to: Proximity Sensor Reversed SomehowIt is because the IR signal from the proximity sensor is reflecting back from the white dots on the inside of the screen, so it is being prevented from passing through the glass, the way I solved it was to remove the mylar sticker and colour over the white dots lightly with a black marker pen, you can't see the black marker from the front but when you hold the screen up to the light and look through from the proximity sensor side you should be able to see through it and it has sort of a red look to it. This seems to allow the IR signals to pass both ways through the glass. If you look through the black glass display you will see the same sort of colour when held up to the light. Hope this helps, it solved the problem for me. Just be aware that if it doesn't work the marker pen is virtually impossible to remove without damaging the screen.
