Missing Facebook notifications on your vivo S50 can make you feel disconnected from messages, comments, and important updates. Sometimes the app works fine, but alerts simply never appear. In most cases, this happens because of notification permissions or battery restrictions that quietly block Facebook in the background.
Let’s go step by step and restore your alerts.
Why Facebook Notifications Are Not Working on vivo S50
- Notifications are disabled inside the Facebook app.
- System notification permissions are turned off.
- Battery optimization is restricting background activity.
- Do Not Disturb mode is enabled.
- Background data usage is limited.
Check Facebook Notification Settings Inside the App
If notifications are disabled within Facebook itself, your phone will never show alerts even if system settings are correct. This is the first thing you should verify.
Open the Facebook app, and then tap the Menu icon.
Tap Settings and privacy, and then tap Settings.
Tap Notifications, and then make sure push notifications are enabled.
Allow System Notifications for Facebook
Even if Facebook notifications are enabled inside the app, Android may block them at the system level. You need to confirm that notification permissions are allowed.
Open Settings, and then tap Notifications.
Tap App notifications, and then find and tap Facebook.
Toggle on Allow notifications, and then enable all notification categories.
Disable Battery Restrictions for Facebook
Your vivo S50 may stop Facebook from running in the background to save power. When this happens, notifications get delayed or completely blocked.
Open Settings, and then tap Battery.
Tap Background power consumption management, and then find Facebook.
Set it to Allow background activity, and then remove any power restrictions.
Make Sure Background Data Is Enabled
Facebook needs mobile data or Wi Fi access in the background to deliver notifications instantly. If background data is disabled, alerts may not arrive until you open the app.
Open Settings, and then tap Apps.
Tap Facebook, and then tap Data usage.
Enable Background data, and then enable Unrestricted data usage if available.
Turn Off Do Not Disturb
Do Not Disturb mode silences calls, messages, and app alerts. You may not realize it is active, especially if it runs on a schedule.
Open Settings, and then tap Sound and vibration.
Tap Do Not Disturb, and then toggle it off.
Check the schedule settings, and then disable any automatic activation.
Restart Your Phone
Sometimes the issue is just a temporary system glitch. A quick restart refreshes background services and restores notification syncing.
Press and hold the Power button, and then tap Restart.
Wait for the device to reboot, and then test Facebook notifications again.
Once permissions and battery settings are properly configured, your vivo S50 should start receiving Facebook alerts normally. Most notification problems are caused by restrictions that quietly block apps in the background.
FAQs
Why do I only receive Facebook notifications when I open the app?
This usually means background activity is restricted. Removing battery optimization and enabling background data should fix it.
Why are Facebook Messenger notifications working but not Facebook app notifications?
Messenger and Facebook are separate apps with different notification settings. Make sure notifications are enabled for both in system settings.
Can clearing Facebook cache fix notification issues?
Yes, clearing cache can remove corrupted temporary files. Go to Settings, tap Apps, tap Facebook, then tap Storage and clear the cache without deleting data.
