Use pinning to keep the current app in view until you unpin it. For example, you can pin a game and your child cannot navigate anywhere else on your phone.

You can set up a pattern, PIN, or password required to unpin.

1. Go to Settings > Security & location > Advanced > Screen pinning.
2. Turn pinning on.
3. By default, you must always enter your pattern, PIN, or password when unpinning a screen. If you don't want this security before accessing your other phone screens, turn this option off.

To pin a screen:

1. Make sure you've turned on screen pinning.
2. Open an app and go to the screen you want to pin.
3. Touch .
4. Touch the icon of what you want to pin.
5. Touch .

To unpin it:

1. Touch & hold and at the same time.
2. If you required a pattern, PIN, or password when you turned on pinning, enter it to unlock the phone.
