I've had one. I call this the "Sometimes" phone. Sometimes the AOD is on, but not always. Sometimes it vibrates for no reason I can discern. Sometimes in disconnects from the bluetooth in my car, but reconnects quickly; fun during a phone call. Sometime the iris scanner works, but sometimes it says I need to registers and activate it (again). Sometimes the finger scanner works, sometimes it doesn't. I feel like I've got a rebellious phone. And I just can't do a reset again. But, battery life is great (until VZW craps that up with their updates), always wireless charges perfectly. Alarm clock has gone off every day when it's supposed to, so there's that.
