Screen lock
Use Screen lock 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 lock feature prevents the active game app screen from being minimized.
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 lock 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.

Application settings
Some apps will ask for permissions once you start using them. You can allow or
deny permissions individually for each app, either from the Settings menu or from
the Permission confirm dialog. Permission requirements depend on the app’s
design.
Allowing or denying permissions
You can choose whether to allow or deny permissions when the dialog is shown. If you
have used another Android version previously, most apps will have already been
granted the necessary permissions.
