My Iphone 5 "End Call" dose not work.
When I am finished with my call I attempt to push the 'End Call' button. The button color changes, signifying an action implimented, but then the screen flashes black then reappears and I am still in the call(timer running). If I depress the home button I return to my home screen with the green banner at the top signifying that I am still in a call. The only current way to terminate my calls is by depressing the power button on top. Unlock slider works and no trouble in any other app in that part of the screen. Is this a known issue, any solutions?
iPhone 5, iOS 6.0.1
