The camera shutter is a mechanical component that prevents any attempt from capturing your image, thus protecting your privacy. To cover the camera lens, slide the camera shutter to the left. When you want to use the camera, slide the camera shutter to the right.
If you slide the camera shutter to the left during a video call , people on the video call will not be able to see you. If you slide the camera shutter back to the right, they will be able to see you again.
