If you are using a phone, it will initially show the rear-facing camera of both phones in the video feed.
To switch the video, click or touch the swap icon on the lower left area of your screen. If you are on a computer, you can do this by clicking your mouse. If you have a touch screen tablet or phone, you can do this by tapping the icon with your finger.

There’s always a main screen and a small screen. If you want to change the small screen to the main screen, touch or click on it and the screens will trade places. If you are showing something specific to the other person, you’ll want the camera that is showing the focus of the call to be the main screen.
