The green light next to the camera comes on when opening any app.
Using an iPhone 16 running iOS 18.1.1, each time I open an app the green light to the left of the camera comes on for a few seconds. Some of the apps don’t use the camera at all. Sometimes it does the same thing when unlocking.
A hard restart stops it but only for a short while.
The user manual says it’s the camera that’s been accessed by an app, but it’s not telling me which app, only camera.
iPhone 16, iOS 18
