Turn notifications from an application on/off

1. Open Notifications.
2. Under Applications, turn the application's switch on or off.

An application that is off can't put a banner on the screen. It can still do everything else it does. System messages, such as a low battery or a missed call, arrive whatever you set here.

There's no switch for all notifications at once. If you see Currently off, something such as a call has paused notifications for everything, and they come back on by themselves.

To choose whether notifications show when the screen is locked, see Get notifications when the screen is locked or off.
