Why won't the proximity sensor respond?
I have replaced the screen on a black iphone 4. Normally if the sensor stops working, it is because the new screen is a light colored one like pink. This one is black but since the sensor isn't responding, I bought one of those sticker pads to put over the sensor. Still not working. I used a permanent marker on the back of the screen where the light shines through. Same result. Restored the phone to 5.1 and wiped out everything. Still the same. Bought a new sensor. Still not working. Went out and bought ANOTHER screen. Same thing.
So frustrating especially since they won't update that CallLock tweak so it is compatible with ios5. Anyone able to help?
