If you skipped iOS 12.1/iOS 12.1.1, you'll get Group Face Time calls.
When running iOS 12.1/iOS 12.1.1/iOS 12.1.1, FaceTime group video calls are integrated right into Messages making it easy to start up a group call with co-workers, family members, or friends.
The feature supports up to 32 callers on one call, but you'll only see the people talking or people you want to focus on on the screen. Everyone else is shown in a roster on the bottom of the call.
Group FaceTime calls allow you to add your Memoji or Animoji if you own an iPhone X, iPhone XS, or iPhone XS Max and you can also use filters if your heart desires.
iOS 12.1 also brought some other improvements to FaceTime including:
- Automatic detection of active speakers: FaceTime uses on-device intelligence to display the most prominent speakers on the call, automatically highlighting the current speaker by bringing them to the forefront. It automatically sizes each person’s image depending upon how active they are in the conversation, based on duration of speech, volume and even motion. Participants who are not active will appear at the bottom of the screen until they speak. A simple tap also brings a participant front and center.
- Ringless notification: When calling more than one person, FaceTime displays a notification that lets you instantly join a call without being disruptive.
- Messages integration: Group FaceTime is integrated into the Messages app, making it easy to start a Group FaceTime right from a group iMessage chat. If people in a conversation have already started a FaceTime session, Messages shows the active call in the conversation list and inside your conversations.
- Private: All FaceTime conversations, both one-to-one and multi-person, are encrypted end to end so they remain private and viewable only by the participants.
If you're a heavy FaceTime user, and you skipped iOS 12.1/iOS 12.1.1, you'll probably want to install iOS 12.1.2.
