Proximity Sensor not powered after battery replacement
I recently replaced the battery in the iphone 3gs. Everything is working correctly except for the proximity sensor. I used a camera (iphone 4) to test to see if the sensor was lighting up during a call and it wasn't.
My investigations informed me that connector 3 is responsible for both the proximity sensor and the earpiece audio. I re-examined the cable and connector and everything looks undamaged and well seated. However, the sensor still won't work.
