Screen pinning
Use screen pinning to set your device to display only the screen for a specific
application. For example, if you are playing a game and you accidentally touch the
Home navigation key, the screen pinning feature prevents the active game app
screen from being minimised. You can also use this feature when you lend your
device to another person to make it harder for them to access more than one
application. For example, you can lend your device to somebody to take a photo and
pin the screen to the Camera application so that the person can't easily use other
apps such as Email.
Screen pinning is not a security feature and does not fully prevent other users from unpinning
a screen and accessing your device. To protect your data, you should set up your device to
request a screen lock PIN, password or pattern before someone can unpin the screen.
