Hi! I've had my HTC 8X on Verizon for about a month now and it's been great so far besides this one issue; when attempting to end a call, I have to tap "End" repeatedly to end the call and even then it takes 7-10 seconds for the call to end. Is anyone else having this issue because when I first bought the phone, making and ending calls were very snappy; no waiting for the call to end, just tap "End" and go back to the homescreen. I really hope this isn't a bug because it doesn't seem like Verizon will be issuing an update anytime soon (as I'm also having issues with my SIM card not responding until I reboot the phone and my Speaker crackling when anything is playing through it as well as having had two reboots already) but I don't want it to be an OS issue that I just have to deal with. When you get a phone, you expect the PHONE to work if nothing else works. Haven't had this issue with my iPhone 4S or my Galaxy Nexus. Even iPhone 5's can make and end a call snappy. WP8 is amazing but if it can't even end a call well, then it's no use to me.
