You glance at your Galaxy S25 Ultra, expecting to see new alerts on the lock screen. Nothing appears.
Messages arrive, apps send notifications, yet the lock screen stays empty. This usually happens when certain notification settings are disabled or restricted in One UI 7.
The good news is that you can restore lock screen alerts with a few quick adjustments.
Why Lock Screen Notifications Are Not Showing on Your Galaxy S25 Ultra
- Lock screen notifications are disabled in the notification settings.
- Notification content is hidden for privacy.
- Do Not Disturb mode is blocking alerts.
- Specific apps are not allowed to send notifications.
- Software glitches temporarily prevent alerts from appearing.
Turn On Lock Screen Notifications
If lock screen alerts are disabled, your phone will receive notifications but will not display them when the device is locked. Turning this feature on allows notifications to appear directly on the lock screen.
- Open Settings, and then tap Notifications.
- Tap Lock screen notifications, and then toggle it On.
Once enabled, new alerts should appear whenever your phone is locked.
Show Notification Content on the Lock Screen
Sometimes notifications appear, but their content is hidden. You may only see icons instead of the actual message or alert preview.
Allowing full notification content lets you read the message or see details without unlocking the phone.
- Open Settings, and then tap Lock screen.
- Tap Notifications, and then choose Show content.
Lock the phone again and wait for a new notification to confirm it works.
Check Do Not Disturb Mode
Do Not Disturb silences notifications and can prevent them from appearing on the lock screen. If this feature is active, alerts may not show until the mode is disabled.
- Open Settings, and then tap Notifications.
- Tap Do Not Disturb, and then toggle it Off.
You should start seeing notifications again after disabling the feature.
Make Sure the App Can Send Notifications
Some apps may have their notifications turned off individually. When this happens, alerts will not appear anywhere, including the lock screen.
- Open Settings, and then tap Notifications.
- Tap App notifications, and then select the app that is not showing alerts.
Once you open the app’s notification settings, make sure the notification switch is turned on.
Restart Your Phone
Temporary system glitches can also interfere with notifications. Restarting the phone refreshes background services and restores normal behavior.
- Swipe down from the top right of the screen, and then tap the Power icon.
- Tap Restart, and then wait for the phone to reboot.
After the device restarts, lock the screen and test notifications again.
Lock screen notifications are meant to make your Galaxy S25 Ultra more convenient. Once the correct settings are enabled, alerts should appear instantly without unlocking your device.
