iPhone 6 occasionally goes to a blank screen during a call
Every so often (1 or 2 times out of 30-40 calls if I were to guess) while talking on my iPhone 6 (64GB), I'll pull it away from my ear and the screen is off. I'm holding it around the edges and not obscuring any sensors. Tapping the screen, pressing the home button, the sleep/wake button or volume buttons does nothing. Twice this has happened while leaving a message so I have to do a forced restart.
I'm on iOS 8.1.2 but this also happened on either 8.1.1 or 8.1 before (not sure if I skipped an update or installed them all). I've never had this problem on my 3GS or 4S. I've thought about taking it into an Apple store but I can't repro it on demand.
Anyone else have this problem?
