Random question, I've created a camera app and on iOS, the green dot (signifying that the camera is in use) stays on even when the camera screen is not in use. Do I need to "close" the camera when it's not in use or anything like that? Thanks!
Until you unmount your camera screen, the camera will be in use.
When you unfocus the camera screen, use the pausePreview() method: https://docs.expo.dev/versions/latest/sdk/camera/#pausepreview
When you focus on the screen, use the resumePreview() method instead: https://docs.expo.dev/versions/latest/sdk/camera/#resumepreview
