When you’re scrolling through Facebook’s app, the social network could be using your camera, concerned users have found. Multiple people have found and reported that their iPhone cameras were turned on in the background while they were looking at their feed.
The issue came to light through several posts on Twitter. Users noted that their cameras were activated behind Facebook’s app as they were watching videos or looking at photos on the social network.
After people clicked on the video to full screen, returning it back to normal would create a bug in which Facebook’s mobile layout was slightly shifted to the right. With the open space on the left, you could now see the phone’s camera activated in the background.
