FaceTime can now be used across platforms, with Android phones or Windows devices connecting for video calls on Apple hardware. Formerly only Apple devices could make and accept FaceTime calls. Calls take place using a compatible web browser on the Android or Windows device, with iOS, macOS, or iPadOS version 15 or later on the Apple side.
Other improvements to FaceTime have been included with iOS 15, such as SharePlay. SharePlay makes it possible to watch videos, listen to music, and share your screen during FaceTime calls.
