Your Android phone may allow for notifications to be displayed on the Lock screen, similar to how notifications are listed on the notifications drawer. You can set which notifications appear and how they’re displayed, which helps add to the phone’s security.
To configure Lock screen notifications, follow these steps:
Open the Settings app.
Choose Sound & Notification.
This item might be titled Sounds and Notifications.
Choose When Device Is Locked.
Another title for this setting is Notifications on Lock Screen.
Select a Lock screen notification level.
Up to three settings are available:
Show All Notification Content
Hide Sensitive Notification Content
Don’t Show Notifications at All
The names of these settings may be subtly different on your phone.
Choose a notification level.
If your phone features a secure screen lock, the Hide Sensitive Notification Content option appears (refer to Step 4). When chosen, the Lock screen displays notices, not message previews or content.
To make the Lock screen notifications useful, double-tap one. The app that generated the notification starts, and you can see more details. Of course, you have to first work the screen lock.
