How to Fix Background App Notification Not Working on vivo X300 Pro

Missing notifications can make you miss important messages, alerts, or reminders on your vivo X300 Pro. You may open an app and suddenly see several messages that arrived hours earlier.

This usually happens when the system restricts background activity, battery optimization blocks the app, or notification settings are turned off. The good news is that most notification issues can be fixed with a few quick adjustments.

Why Background App Notifications Are Not Working on vivo X300 Pro

• The app’s notification permissions are turned off.
• Battery optimization is restricting background activity.
• Background data is disabled for the app.
• Do Not Disturb mode is blocking alerts.
• System notification settings were changed after an update.

Check If App Notifications Are Enabled

If notifications are disabled for a specific app, the system will not display alerts even when the app receives messages.

Turning the permission back on usually restores notifications instantly.

1. Open Settings, and then tap Notifications.
2. Tap App notifications, and then select the app you are having problems with.
3. Toggle on Allow notifications, and then enable all alert types you want to receive.

Allow the App to Run in the Background

Some apps need permission to run in the background so they can receive new messages or updates.

If this permission is restricted, the app will only refresh when you open it.

1. Open Settings, and then tap Apps.
2. Tap App management, and then choose the affected app.
3. Tap Background activity, and then allow the app to run in the background.

Disable Battery Optimization for the App

Battery optimization can stop apps from working normally in the background.

Disabling optimization for important apps ensures they stay active and continue sending notifications.

1. Open Settings, and then tap Battery.
2. Tap Battery optimization, and then locate the affected app.
3. Select the app, and then choose Don’t optimize.

Make Sure Background Data Is Enabled

If background data is disabled, the app cannot connect to the internet when it is not open.

This prevents the app from receiving messages or updates in real time.

1. Open Settings, and then tap Network and internet.
2. Tap Data usage, and then select the affected app.
3. Toggle on Background data, and then confirm the change.

Turn Off Do Not Disturb Mode

Do Not Disturb can silence notifications without disabling them completely.

Many users forget that it is active, especially if it was enabled automatically through a schedule.

1. Open Settings, and then tap Sound and vibration.
2. Tap Do Not Disturb, and then switch the feature off.
3. Check the schedule settings, and then disable any automatic activation.

Background notifications are essential for messaging apps, email alerts, and reminders. Once permissions, background activity, and battery settings are properly configured, your vivo X300 Pro should start delivering notifications normally again.
