Answer 1

Pin & unpin screens

You can pin an app's screen to keep it in view until you unpin it.

For example, you can pin an app and hand your phone to a friend. With the screen pinned, your friend can use only that app. To use your other apps again, you can unpin the screen.

Important: You're using a custom Android version. If these steps don't work for you, check with your device manufacturer.

Turn on screen pinning

Open your phone's Settings app.

Tap Security or Security & location and then Advanced and then Screen pinning.

If you can't find it, get help from your device manufacturer.

Turn on Screen pinning.

When screen pinning is on, you need to enter your PIN, pattern, or password before you can unpin.

After turning on screen pinning:

Swipe up to the middle of your screen. If this doesn't open your Overview, go to the steps for Android 8.1 & below.

At the top of the image, tap the app's icon.
