Missing lock screen notifications on the vivo S50 can make you miss important messages, calls, or app alerts. You might hear a sound or see nothing at all when the screen is locked. This problem is usually tied to notification settings, battery restrictions, or app permissions, and most fixes take only a minute to apply.
Why Lock Screen Notifications Are Not Showing on Your vivo S50
- Lock screen notifications are disabled in system settings.
- The affected app is not allowed to show notifications on the lock screen.
- Battery optimization is restricting background activity.
- Do Not Disturb mode is turned on.
- The app notification channel is disabled or misconfigured.
1. Make Sure Lock Screen Notifications Are Enabled
Lock screen notifications can be turned off globally, which blocks all apps from showing alerts when the screen is locked. Turning this back on allows notifications to appear normally again.
Open Settings, and then tap Notifications.
Tap Lock screen notifications, and then choose Show all notifications.
2. Check Notification Settings for the Affected App
Even if system notifications are enabled, individual apps can still be blocked. This is common after app updates or permission changes.
Open Settings, and then tap Notifications.
Tap App notifications, and then select the app that is not showing alerts.
Make sure Allow notifications and Lock screen notifications are both enabled.
3. Disable Battery Optimization for the App
Battery saving features on the vivo S50 can prevent apps from running in the background. When this happens, notifications may not arrive until you open the app.
Open Settings, and then tap Battery.
Tap Background app management, and then select the affected app.
Set it to Allow background activity.
4. Turn Off Do Not Disturb Mode
Do Not Disturb can silence notifications and hide them from the lock screen. This is easy to miss if it was enabled earlier.
Open Settings, and then tap Sound and vibration.
Tap Do Not Disturb, and then turn it off.
Lock your phone and test notifications again.
5. Check App Notification Channels
Some apps use multiple notification channels, and important alerts may be disabled even when notifications are allowed. This is common with messaging and social media apps.
Open Settings, and then tap Notifications.
Tap App notifications, and then choose the affected app.
Review each notification category and enable the ones you need.
6. Restart Your Phone
A restart refreshes system services that handle notifications. It can fix temporary bugs that stop alerts from appearing on the lock screen.
Press and hold the Power key, and then tap Restart.
Wait for the phone to boot up, then test notifications again.
Once lock screen notifications are enabled and background restrictions are removed, alerts on your vivo S50 should appear normally again. These fixes address the most common causes without affecting your data or apps.
FAQs
Why do notifications only appear after I unlock my vivo S50?
This usually means the app is restricted from running in the background. Disabling battery optimization for that app often resolves the issue.
Can a screen lock type affect notifications?
Yes. Certain lock screen styles or privacy settings may hide notification content. Adjusting lock screen notification visibility fixes this.
Do system updates affect lock screen notifications?
Yes. Updates can reset notification permissions or battery settings. Checking notification and battery options after an update is recommended.
