Method 1: Turn notifications back on for the affected apps

A software update may change app notification categories or silently disable alerts.

1. Open Settings > Notifications > App notifications.
2. Enable notifications for the affected apps.
3. Open the app notification categories and make sure lock screen, sound, and pop-up alerts are enabled.

Method 2: Remove apps from sleeping and deep sleeping lists

Samsung battery management can stop notifications when apps are heavily restricted.

1. Go to Settings > Battery > Background usage limits.
2. Remove the affected apps from Sleeping apps and Deep sleeping apps.
3. Set important apps to Unrestricted battery use.

Method 3: Check Do Not Disturb, Modes, and lock screen alert settings

Profiles created before the update may still be blocking alerts.

1. Open Settings > Notifications > Do not disturb.
2. Turn it off temporarily.
3. Also review Modes and Routines and Lock screen notifications.

Method 4: Clear cache for the affected app and sign in again if needed

Push tokens can become invalid after major app or system updates.

1. Go to Settings > Apps > choose the affected app > Storage.
2. Tap Clear cache.
3. If needed, tap Clear data and sign back in to refresh push registration.

Method 5: Update Google Play services and Samsung system apps

Notification delivery relies on current background services.

1. Open the Play Store and update your apps and Google services.
2. Open Galaxy Store and install pending Samsung system updates.
3. Restart the phone afterward.

Method 6: Reset app preferences

Disabled default services can break banner alerts, badges, or background delivery.

1. Open Settings > Apps.
2. Tap the three-dot menu.
3. Select Reset app preferences and confirm.

Method 7: Reset network settings

Broken Wi-Fi or mobile data configuration can stop pushes from reaching the device.

1. Go to Settings > General management > Reset.
2. Tap Reset network settings.
3. Reconnect to your network and retest notifications.

Method 8: Install the next patch update if available

If the problem began immediately after one firmware build, Samsung may already have a hotfix available.

2. Install any pending update.
3. Test notifications again with the screen locked and unlocked.
