Missing Facebook notifications on your RealMe 16 can make you feel disconnected, especially when messages or alerts arrive late or not at all. This usually happens because Android aggressively manages background activity, or because notification permissions were changed without you noticing. The fixes are straightforward, and you can restore alerts in just a few minutes.
Why Facebook Notifications Are Not Working on RealMe 16
- Notifications are turned off for the Facebook app.
- Battery optimization is restricting Facebook in the background.
- Background data is disabled for the app.
- Data Saver is limiting notifications.
- The Facebook app is outdated or glitched.
1. Make Sure Facebook Notifications Are Enabled
If notifications are disabled at the system level, Facebook cannot send alerts no matter how the app is configured. This is the first thing you should check because it instantly explains why nothing shows up.
Open Settings, and then tap Notifications.
Tap App notifications, and then find and tap Facebook.
Turn on Allow notifications, and then review alert types like messages and reactions.
2. Allow Facebook to Run in the Background
Facebook needs background access to deliver notifications in real time. If background activity is blocked, alerts may only appear when you open the app.
Open Settings, and then tap Apps.
Tap Facebook, and then tap Battery usage.
Select Allow background activity, and then exit the menu.
3. Turn Off Battery Optimization for Facebook
RealMe phones use battery optimization to save power, but this can delay or block notifications. Disabling optimization for Facebook allows alerts to come through consistently.
Open Settings, and then tap Battery.
Tap App battery management, and then select Facebook.
Choose Don’t restrict, and then confirm your selection.
4. Check Background Data Access
Without background data, Facebook cannot refresh content or push notifications. This often happens when data limits are enabled.
Open Settings, and then tap Mobile network.
Tap Data usage, and then select Facebook.
Turn on Background data, and then return to the home screen.
5. Disable Data Saver
Data Saver limits background internet usage, which can interfere with notifications. Turning it off ensures Facebook can communicate freely in the background.
Open Settings, and then tap Mobile network.
Tap Data Saver, and then switch it off.
Test notifications by locking the phone for a few minutes.
6. Update the Facebook App
An outdated app version may contain bugs that affect notifications. Updating ensures compatibility with the latest system features.
Open the Play Store, and then tap your profile icon.
Tap Manage apps and device, and then find Facebook.
Tap Update if available, and then restart the app.
Facebook notifications on the RealMe 16 usually fail due to background limits or permission changes. Once you allow notifications, background access, and data usage, alerts should return to normal almost immediately.
FAQs
Why do Facebook notifications only appear when I open the app?
This usually means background activity or background data is restricted. Allowing Facebook to run in the background fixes delayed alerts.
Does battery saving mode affect Facebook notifications?
Yes. Battery saving features can pause background processes, which prevents notifications from arriving on time.
Should I reinstall Facebook if notifications still do not work?
Reinstalling can help if the app files are corrupted. Try it only after checking notification permissions and battery settings first.
