I tried to make a call and it got stuck at "dialing" so I pressed the end button to try again. It ended the dialing process but would not get out of the call screen. When I clicked home it still showed the call icon in the notification bar and when I went back to the dialer it was still on the call screen. Not wanting to pull the battery (because I have a hard cases on and it's just a pain) I force stopped the dialer but that just made me loose network connection. I ended up pulling the battery and all seems well for now. Just wanted to give you guys a heads up. Seems like an Android issue not a phone issue and hope it was a one time fluke. We will see!
