How can I repair a proximity sensor?
I followed the directions to repair the proximity sensor on an iPhone 3GS, but when I put the phone back together, the problem persisted: my phone screen remains on when I hold it to my face during a call. I repaired the glass over the screen a couple weeks ago, and since then the proximity sensor has not functioned. During the repair of the sensor, I had difficulty getting the metal piece covering the sensor up, since I don't have an automotive tool. I used a screw driver, and upon pulling out the sensor and putting the new one back in, the entire piece seemed less secure. Is there a way to be certain that the sensor is the problem? Should I look at other alternatives?
Is this a good question?
