Voice Control. Need I say more? It wasn't a bug, really, but every time I bent over and had my iPhone 6+ in my pocket, that stupid Voice Control would wake up and yak at me. No, in the grand scheme of things, this wasn't a world shaking problem. But it was a real irritant. Now, with IOS 10.2, this can be TURNED OFF. I know about the Siri password workaround, but this is finally the right solution, not some hack. Thanks, Apple. Honestly, this was the one thing that got me so mad that I was seriously considering tossing my iPhone. First world problems and all that, sure. But it's nice to have this option now.
