Ok so you know how the proximity sensor glows red now when in a phone call? Well when I answer a call, I see the red light come on, and then it goes off and I go back to having proximity problems.. But if when answering the call I put my thumb over the sensor it will stay red for the remainder of the phone call. (I can also do this by turning speaker phone on/off and holding my phone over the sensor) Anyone else had this problem? Any fix?
