Hi, I tried out FaceTime on my iPhone 5 today, and a few times the video would go away for a few seconds, (but not audio.) We both noticed a marked improvement in video quality, so we were wondering if it had to do with our fairly weak D-Link routers. We were both pretty close to them, though. Never had an issue with my 4. Has anyone experienced FaceTime blacking out video on the iPhone 5 (or iOS 6)?
