Video chat and phone calls
Video chat
While doing a video call using a third-party video chat app, you can use Face Tracking
to keep your face in view at all times. You can also use Screen Share to share your
phone screen with the person you're calling.
Face Tracking
During a video chat, Face Tracking focuses on your face and others around you, and
tracks faces that are within the camera's angle of view. Face Tracking can track a
maximum of 4 faces.
1. Open your video chat app, and then tap
to open the menu.
2. Tap
to turn on Face Tracking. As other people around you enter the front
camera's field of vision, each person will appear in a window on the video chat
screen. Your camera will zoom in or out to keep the faces in focus when you
move.
