I've never had great cell service in my house, but lately it seems to be significantly worse than usual. But my moto droid will have the bottom 3 bars of the reception icon filled, but then as soon as I initiate a call, they all go gray. Then when I end the call, my service goes back up. And while on a call, I have a lot of trouble hearing the other person, and they drop in and out. Anyone experience this or anything like it? Could it be the phone itself that is defective? Is there anything I can do to improve cell service? Any help is enormously appreciated.
