Ok I was on thee phone with my girlfriend and my phone hung up by itself. I tried to call her back, the phone menu came up but it never dialed out. I did a battery pull and tried to call her back 4 times and it still did the same thing. I can't call anyone. All it does is shows the menu like I'm making a call but the numbers never dial and it hangs up without saying disconnected. It just started doing it.
