First time poster, just wanted to make sure I am doing the right thing. My phone will sometimes not ring at all when I receive an incoming call. It will be waiting for me to pickup, but nothing will be coming out of the speakers. Also, sometimes when someone calls it rings and rings on their end and go to my voice mail, but my phone will not even register that they called. Oh, and it randomly revolted once or twice just sitting there. I am probably going to exchange my phone, but I wanted to see if that is the best course of action.
