I occasionally like to use my Droid X as a phone - yes, it has that feature, too, in addition to everything else it can do. Here's the problem. When I place a call, it goes through, but I hear absolutely nothing, not even the ringing. The person I am calling hears their phone ring, but they cannot hear me, and I cannot hear them. This happens almost every day. Sometimes, if I shut down and restart - which takes time - it will work OK. Sometimes I have to do that restart a couple of times. Is this a common problem? Is there a solution?
