回答“Proximity Sensor Reversed Somehow”I replaced the prox ribbon in my phone because the lock button stopped working and now the prox does not work. I tried 2 different new ribbons and haven't had any luck. The crazy thing is the sensors work if I plug them in the phone "free air" but do not work when installed in the OEM location. I am talkie about a phone that has an OEM front. It's almost as if it does an initialization on restore, or the sensor is not centered correctly in the holes ( which is almost impossible). I tried I moved it around and tried three different sensors with no luck.
