During a FaceTime call, you can share your entire screen with the other person — great for walking someone through settings, showing them something on your phone, or troubleshooting together.

How to use it

1. Start or join a FaceTime call
2. Tap the Share Content button (the screen-sharing icon in the call controls)
3. Select Share My Screen
4. A 3-second countdown appears, then your screen is broadcast to everyone on the call
5. To stop sharing, return to FaceTime and tap Stop Sharing
