The Facebook app for Android is awful 50% of the time. It doesn’t upload photos properly and they are forever stuck in the notification area since there is no way to cancel them. Clear them with these steps.
Note: These steps may clear custom settings in the Facebook app such as notification sound.
- Open “Settings“.
- Choose “Apps“.
- Select “Facebook“.
- Select “Storage“.
- Tap the “Clear Data” button.
- Tap “OK” to confirm your selection.
Restart the device, then fire up the Facebook app again, and the stuck upload should now be cleared.
If this happens regularly, you may want to consider just using the Mobile Facebook site. It provides a more reliable option for uploading photos than the app.
