How to Fix Android Notifications Not Showing

Fix missing Android notifications with these proven troubleshooting steps. Check settings, clear cache, disable battery optimization, and more.

Check notification settings for the affected app. Open Settings > Apps > [App name] > Notifications. Ensure notifications are enabled and not blocked. Check that the notification category you need is turned on, as some apps separate notifications into channels like Messages, Calls, or Alerts.
Disable battery optimization for the app. Navigate to Settings > Battery > Battery optimization. Find the problematic app and select 'Don't optimize'. Battery optimization can prevent apps from running in the background and delivering notifications on time.
Clear the app's cache and data. Go to Settings > Apps > [App name] > Storage > Clear Cache, then Clear Data if cache clearing doesn't work. This removes corrupted files that might prevent notifications from functioning properly. You'll need to log back into the app after clearing data.
Reset notification settings system-wide. Open Settings > Apps & notifications > See all apps > System apps > Notification Service > Storage > Clear Data. Restart your device after this step. This resets the entire notification system to default settings.
Check Do Not Disturb and Focus mode settings. Verify that Do Not Disturb isn't active by checking Settings > Sound > Do Not Disturb. If using Focus modes or similar features, ensure the problematic apps are allowed to send notifications during active focus sessions.
Update or reinstall the problematic app. Check Google Play Store for app updates. If the app is current, uninstall and reinstall it completely. Outdated apps may have notification compatibility issues with newer Android versions.
Restart notification services. Enable Developer Options by tapping Build Number seven times in Settings > About Phone. Then go to Developer Options > Running Services and force stop 'Notification Manager' and 'System UI'. These services will restart automatically.
