Support HTC One X stuck ringing sometimes when I get a call

view story

http://androidforums.com – Sometimes when I get a call while the phone is locked it is stuck on the accept/decline screen. While its stuck the screen is unresponsive and the ringtone will not stop playing. I have to do a force shutdown with the power button to get it to stop. This has happened with 2 different htc one x's. Is this a known issue? (General)
