FaceTime or Enjoy a Movie with Picture in Picture (PiP)
iPadOS already had this feature, but now it’s coming to iOS as well. Picture in picture allows you to watch supported videos, even when you are doing other things on your phone. This allows users to be able to continue watching movies or videos, even after exiting the app.
You can move the video around the display, swipe it to the side for audio-only, and change the PiP window’s size with just a pinch. Keep in mind, not all videos support iOS.
In addition to videos, you can also use FaceTime with PiP, allowing you to use other programs while keeping the call active easily.
