With the launch of iOS 15 and iPadOS 15, Apple has made it possible for users to start a FaceTime call with someone who’s using Windows or Android devices by simply sharing a link.
When you’re in a FaceTime call on the web, you can do many of the things you can do in the FaceTime app. You can mute or unmute your microphone, turn your camera on or off, use full-screen mode, or use the flip screen button to switch to your front or rear-facing camera.
You can also see people in your Group FaceTime calls in tiles arranged in a grid. The speaker’s tile highlights automatically, so it’s easy to know who’s speaking.
