Ok everyone. Try this. Put the Droid up to your left ear instead of your right. I tried this and it seems to work. First I called myself from a landline and put the phone to my right ear...the phone lit up while it was to my ear, which meant I could easily (and did easily) face dial. When I moved the phone to my left ear, the phone never lit up. I have been using the phone with my left ear now for about five days and have not accidentally dialed yet. This was after I got one more replacement Droid that instantly started face dialing. The problem obviously has to do with the sensor and something about my head and the way I held the phone to my right ear. I don't quite get it, but it seems to work. I'd love to know if this works for others having the same problem.
