I'm having the same problem with my phone. I checked the contacts and they're fine. The proximity sensor works fine although sometimes I have to press the glass in for it to align properly. I assume this is becuase the adhesive isn't as sticky anymore and so the digitizer isn't sticking to the metal plate, causing the assembly to rise away from the sensor. The speaker phone, button tones, and bluetooth all work. If you have any ideas please respond. I won't hesitate to disassemble my phone again to fix it as I didn't find it too difficult to repair. Thanks =)
