Method 1: Check app notification settings again

Some updates reset app-level alert categories, sounds, or lock screen behavior.

1. Open Settings > Notifications > App notifications.
2. Turn notifications on for the affected apps.
3. Open each affected app and verify alert categories, badges, pop-ups, and sounds are enabled.

Method 2: Turn off battery restrictions for affected apps

Aggressive battery control can delay or block notifications in the background.

1. Go to Settings > Apps.
2. Select the affected app.
3. Tap Battery and choose Unrestricted or remove the app from sleeping app lists in Device care > Battery.

Method 3: Check Do Not Disturb and notification modes

After an update, schedules, Modes, or DND filters may silently block alerts.

1. Open Settings > Notifications > Do not disturb.
2. Turn it off temporarily.
3. Also review Modes and Routines for any profile muting notifications.

Method 4: Disable Adaptive Battery and restart the phone

Battery optimization services sometimes need a reset after firmware changes.

1. Go to Settings > Battery > Background usage limits.
2. Remove important messaging and email apps from sleeping lists.
3. Restart the phone and test notifications with the screen locked.

Method 5: Reset notification preferences for the affected app

Corrupted app data can break push registration after an update.

1. Open Settings > Apps > select the affected app > Storage.
2. Tap Clear cache.
3. If needed, tap Clear data, sign back in, and re-enable notifications.

Method 6: Make sure system services are updated

Google Play services, carrier services, and Samsung system apps handle many alerts behind the scenes.

1. Open the Play Store and update Google Play services, your apps, and carrier services if listed.
2. Open Galaxy Store and install available Samsung updates.
3. Restart the phone afterward.

Method 7: Reset app preferences

This restores disabled system handlers without deleting personal data.

1. Go to Settings > Apps.
2. Tap the three-dot menu > Reset app preferences.
3. Confirm and test notifications again.

Method 8: Reset network settings if push alerts still fail on mobile data or Wi-Fi

Network registration issues can stop apps from receiving notifications reliably.

1. Open Settings > General management > Reset.
2. Tap Reset network settings.
3. Reconnect to Wi-Fi or mobile data, then test push notifications.
