FaceTime Reactions are one of the many new features that have come to iOS 17 since it was released in September. Reactions work in Apple's video-based apps like FaceTime. It reads your body's movements, so when you make certain gestures, Apple responds in kind by playing a corresponding animation or emoji.
For example, if you give the camera a double thumbs-up, Apple shows a thumbs-up emoji on the screen to match you. It's similar to how Apple Messages can recognize specific keywords in your texts and automatically send reactions with it, like balloons with "happy birthday," only now it recognizes specific gestures.
However, you might want to occasionally disable this feature. If you use FaceTime for work or telehealth visits, you might find the animations to be unprofessional or unwanted. Because Reactions are automatically enabled, you'll have to manually turn it off to avoid accidentally triggering them. Here's how.
