iOS10 allows replying to messages without unlocking phone??

Hi everyone,

Is it normal that with iOS10, from the lock screen, straight up upgrade from latest iOS9 release, I can do the following:

Have someone send you a iMessage

Click home button to bring lock screen

Scroll down from top of screen to bring notification screen

Swipe left on the iMessage notification

Click View

Notice the message shows up and actually a keyboard shows up and reply.

Is it actually a feature that you CAN answer someone's iMessages without unlocking the screen? I find this a very concerning security problem and could be disastrous if someone can just open random messages and reply!!!

I notice the same problem when scrolling left on a calendar notification where I actually see portions of the calendar for the day... Someone that does not unlock a phone should not be able to access data like calendar and messages ... or am I over-reacting?

I understand turning off the notification preview for message actually forces you to unlock the phone... but this is not a valid resolution, but a workaround and a problem for those not realizing the behavior by default.

Thanks!
