Do iPhones take pics of you every time you unlock it?

The principles at our school told us every time we unlock our phone it takes a picture of us and it stored in your phone but you can't see it. I think it's complete BS and I want to call them out on it. Just want to get a little info to back my case up. Or maybe I'm wrong…

No, he's lying. I use to own an iPhone. My sister and mother is using an iPhone right note now and it doesn't take pictures every time you unlock it.
