How to Fix Background App Notification Not Working on Galaxy S25 Ultra

Missing important app alerts can be annoying, especially when they don’t appear until you open the app yourself. If background notifications are not working on your Galaxy S25 Ultra, it’s usually due to power management, restricted app permissions, or battery optimization settings.

Here’s how to fix it and make sure your apps alert you in real time.

Why Background App Notifications Might Not Be Working

• Battery optimization is restricting background activity.
• App notifications are disabled or muted.
• Power Saving Mode limits app usage.
• Background data is turned off for certain apps.
• Software bugs affecting One UI or Android 15 performance.

Turn Off Power Saving Mode.

Power Saving Mode helps conserve battery life but can restrict background functions, including notifications. Turning it off ensures apps can run freely in the background.

1. Open Settings, and then tap Battery.
2. Tap Power saving, and then toggle it off.

After disabling it, check if your notifications start appearing again.

Remove App Restrictions.

Some apps may have restricted background activity, preventing them from sending alerts when inactive.

1. Open Settings, and then tap Apps.
2. Choose the affected app, tap Battery, and then select Unrestricted.

This allows the app to work properly, even when the screen is off.

Enable App Notifications.

If you accidentally turned off app notifications, the system won’t alert you at all.

1. Open Settings, and then tap Notifications.
2. Tap App notifications, and then find and toggle on the switch next to the app you want to receive alerts from.

This ensures notifications appear as they should, even when the app is closed.

Allow Background Data Usage.

Apps need access to mobile data or Wi-Fi in the background to push notifications. If this option is turned off, alerts will be delayed or not received at all.

1. Open Settings, and then tap Apps.
2. Select the app, tap Mobile data, and then toggle on Allow background data usage.

Now, notifications will arrive even if the app is not active.

Check Sleeping Apps List.

Samsung’s sleeping apps feature can pause background activity to save power, which can block notifications.

1. Open Settings, and then tap Battery.
2. Tap Background usage limits, and then review the Sleeping apps and Deep sleeping apps lists.

If your important app is listed there, tap the three-dot icon, choose Remove, and then confirm.

Reset All Settings.

If none of the above works, resetting all settings can fix misconfigured system preferences without deleting personal data.

1. Open Settings, and then tap General management.
2. Tap Reset, and then tap Reset all settings.

Restart your Galaxy S25 Ultra afterward to reapply all settings properly.

Background app notifications are essential for staying updated. Once you adjust these settings, your Galaxy S25 Ultra should deliver alerts smoothly, just as intended.
