Facebook is secretly using your iPhone’s camera as you scroll your feed

IPhone users get smarter. Apparently Facebook uses your phone's camera without your knowledge. This camera is working while users are scrolling Facebook News Feed in mobile phones.

This problem surfaced when a user, Joshua Maddox, reported it with Twitter. Joshua's shared footage appears to be running the camera during news feed scrolling.

It seems that this problem has been caused by a Facebook error. Saw nothing
Update: Facebook has confirmed that this is due to a bug, which is working to fix it.
