Has anyone accidently called someone and your trying to do whatever to stop the call from ringing? This happened today when I was scrolling through my contact list and accidently tapped the wrong contact and it started the call. Then my screen went black and I couldn't get back to my call screen to hit the end button. I tried everything to end the call and then my phone completely locked up. I had to eventually power the whole phone off and power back up then it was back to normal. It annoys me how I don't have any control over ending a call that was accidently placed. Then for the phone to lock up really ticked me off.
