So yesterday I called my brother and got no answer so I left a message (he has a Droid X), after leaving the message I tried ending the call with the end call button on bottom, no response, I then heard a voice saying that the message did not go through because I was unheard or lack of connectivity ( not sure of actual message), after this my phone became unresponsive, screen started acting weird, icons were unresponsive etc. I turned phone off and on, no fix, the only thing that worked was pulling the battery. after this everything was fine....until I called him again today, no answer, left him a message ( happy birthday!!) , got same error message, and phone started flaking out again until I pulled battery. So my question is is this just a coincidence or a sign of more problems to come. Should I just not call him anymore?
