I'm using iOS 7 on an iPhone 4. The camera icon just a few seconds ago was randomly grayed out as if it was in use, even though I hadn't used it recently. I dragged the icon to see what would happen and it went back to normal after I dragged it. I personally think that's a little bit creepy... anyone know why it may have done this?
Creepy indeed, this happens when the application is stuck between active and sleep mode. I have seen this behavior before and wouldn't worry about it. By the way welcome to the forums, you should sign up ... Would like to see more of ya.
