About screen pinning
Screen pinning lets you pin one app into the foreground on your device. The feature disables the
your device so that the only way to close a pinned app is to unpin the screen. You can set up screen pinning so that you
must enter your screen lock to unpin the screen.
Screen pinning allows you to let someone else use your device, for example, to play a game or view a video, without
worrying that the person might close the app and access your data.
