Control which apps send notifications
For each app, you can specify how to handle the app's notifications: blocking them, hiding sensitive information from them on the lock screen, or giving them priority and putting them at the top of the list.
- Go to Settings > Sound & notification > App notifications.
Touch the app name and then touch one of the following:
- Block: Never show notifications from this app.
- Priority: Always put notifications from this app at the top of the list.
- Sensitive: For the lock screen, show notifications from this app but hide their detailed contents. Use only if you want to configure specific apps as sensitive. Otherwise, you can hide detailed contents for all apps by using Settings > Sound & notification > When device is locked > Hide sensitive notification content.
TipYou can also change these settings right from a notification. Touch & hold the notification, then touch
