I have a droid eris. What's been happening for a while is that I dial a number, and the call seems like it's going through, but I don't hear a ringing. The person on the other end will pick up the call but I can't hear them and vice versa. Ihave to shut down my phone and start it up again to get the phone to snap out of it. When I very got the phone it worked great. Then the operating system was updated and now the phone is all screwy. Any suggestions?
