First off, I'd just like to say that I am very happy with what I've seen today. It's a step in the right direction. One thing I did notice which I feel is a security flaw is being able to access airplane mode in control centre from the lock screen. Imagine your phone gets stolen. All a thief has to do is to swipe up in the lock screen, tap airplane mode, and just like that, your phone can no linger be found in find my iPhone. I get it, going into the setting app is a bit much just to turn on airplane mode, but do we really need that setting in the lock screen??
