How to Fix Facebook Notifications Not Working on OnePlus 13

Missing important Facebook notifications can be annoying, especially when you rely on them to stay updated. If your OnePlus 13 isn’t showing alerts for new messages, likes, or comments, it’s likely due to notification settings, background restrictions, or app permission issues.

Here’s how you can get Facebook notifications working again.

Why Facebook Notifications Might Not Be Working on OnePlus 13

• Notifications are turned off for Facebook.
• Battery optimization or background restrictions are blocking the app.
• Do Not Disturb mode is enabled.
• Outdated Facebook app or system software.
• Cached data causing delayed alerts.

Enable Facebook Notifications.

Your phone might have app notifications disabled, which prevents Facebook from sending alerts. Turning them back on usually solves the issue instantly.

1. Open Settings, and then tap Notifications.
2. Tap App notifications, and then scroll down and select Facebook.

Make sure Allow notifications is turned on and that all notification types, including message and comment alerts, are enabled.

Allow Background Activity.

If background activity is restricted, Facebook may not update or push notifications when the app is closed.

1. Open Settings, and then tap Apps.
2. Tap Facebook, and then tap Battery usage.

Choose Allow background activity so Facebook can sync and deliver notifications in real time.

Disable Battery Optimization for Facebook.

Battery optimization can delay or block background notifications to save power. Disabling it for Facebook ensures timely alerts.

1. Open Settings, and then tap Battery.
2. Tap Battery optimization, and then find and select Facebook.

Choose Don’t optimize, then confirm. This allows Facebook to run freely even when your OnePlus 13 is idle.

Check Do Not Disturb Mode.

When Do Not Disturb is active, your phone won’t make sound or vibrate for notifications. It can also suppress banners and pop-ups.

1. Open Settings, and then tap Sound and vibration.
2. Tap Do Not Disturb, and then turn it off.

Once it’s disabled, test Facebook to see if notifications start appearing.

Update Facebook and System Software.

Outdated apps or system versions often cause notification bugs. Updating both ensures compatibility and stability.

1. Open the Play Store, and then tap your profile icon.
2. Tap Manage apps and device, and then tap Update all if Facebook appears in the list.

Afterward, open Settings, tap System, then tap System updates. Download and install any available updates for your device.

Clear Facebook Cache and Data.

Corrupted cache files can interrupt how notifications are delivered. Clearing them gives the app a fresh start.

1. Open Settings, and then tap Apps.
2. Tap Facebook, and then tap Storage and cache.

Tap Clear cache, and if the issue persists, tap Clear storage to reset the app’s data.

Once done, log in again and check if notifications are restored.

Getting Facebook notifications back on your OnePlus 13 is usually simple once you adjust the right settings. After applying these fixes, your alerts should appear on time, just like before.
