With Group FaceTime available with iOS 12.1, Apple iPhone and iPad users can participate in a 32-way video chat. The tile showing the person speaking will get larger automatically, as will the tiles of those participating the most in the conversation. Group FaceTime is available on the iPhone 6s or later, iPad Pro or later, iPad Air 2, or the iPad Mini 4. Earlier models can be involved in a Group FaceTime chat through an audio connection only.
