10 ways to fix notification errors are not displayed on Android

Android notification system is No. 1 in the world. But this system is often affected by the manufacturer's custom features or malfunctions in a particular application. These make the system notify you of strange signs or delays, making you miss important warnings.

Fortunately, you can try many methods to return the notification system to normal. Here are some remedies if you don't get the Android notification as usual.

1. Restart the phone

The first step to fixing any problems you encounter is to ensure that it is not a temporary problem. Please restart the phone. Doing so will terminate all processes or services running in the background that may hinder the ability to push notifications.

The reboot will also refresh the main components of the phone, in case any of these components fails while performing the task.

2. Review the application notification settings

If the phone reboots do not work, try reviewing the notification settings for the application that is having trouble. Most major applications provide their own proprietary set of options to modify how often the application can push notifications, what kind of notifications you want to see, etc.

For example, Gmail allows you to completely disable synchronization. So make sure you didn't accidentally press the button to disable that feature while browsing the application settings.

If you don't find the relevant settings in the app, be sure to check Android's notification settings for apps in Settings> Apps & Notifications> [Application Name]> Notifications. Android Oreo and newer versions have a modified notification system, which allows changing settings for different types of alerts.

3. Disable battery optimization for software

To maintain battery life and prevent apps you don't use from working in the background regularly, Android has begun to apply AI-based software optimization. But the algorithms that make up this feature are not perfect and can cause the system to fail.

One of the most common 'victims' of this is the notification system. If you're having this problem, turn off optimization features for a few days.

On Stock Android, you can disable Adaptive Battery in Settings> Battery for all applications. But this is probably overkill. Instead, you can disable battery optimization on specific applications, by visiting Settings> Apps & Notifications> [Application Name]> Advanced> Battery> Battery optimization .

4. Check the manufacturer's exclusive battery savers

Some manufacturers have added more battery-saving tools, automatically blocking supposedly unimportant applications. So you will have to check if your phone comes with any other internal optimization features.

For example, on Xiaomi phones, there is a preloaded application called Security, which contains some such functions.

5. Reinstall the application or wait for the updates

In case there is only one problem with an application, it is possible that the developers accidentally launched an error update. For this situation, you have 3 options: Remove and reinstall the application, wait for the update to fix the problem or go back to the older version. If you want to go back to the older version, you can visit the website like APKMirror.com to find the application you want to reinstall.

6. Check the Do Not Disturb mode

Most Android phones have a handy Do Not Disturb mode. This mode is designed to block all notifications, except for those allowed by the user. Software designers tend to place this mode switch button in easily accessible places such as the Quick Settings section . Therefore, if you are not familiar with this feature, it is likely that you accidentally triggered the error.

Go to Settings and in Sound or Notifications (depending on specific Android device), then find Do Not Disturb mode. If you don't find this feature in one of these locations, search for Do Not Disturb in the search bar at the top of the Settings section .

7. Is background data enabled?

The Data Saver feature allows you to limit the amount of application data used when WiFi is not turned on. This feature can help save money, but may also cause you to miss important notifications.

To confirm that Data Saver mode is not the cause of the error, use your phone but do not activate this feature for a while (if you are currently activating it), by visiting Settings> Network & internet> Data Usage> Data Saver .

9. Is the application allowed to operate in the background?

From Android Oreo or later, you have the ability to force applications completely inactive, when you don't really need to use them. This feature will disable applications that consume too much phone battery capacity. This is definitely a convenient add-on, which helps to protect your phone's battery life.

However, this can also cause notification-related problems, if enabled for critical applications. Unfortunately, Android can change this if it is necessary. Therefore, you should review the settings for applications that are having notification problems, by going to Settings> Apps & Notifications> [Application Name]> Battery> Background Restriction .

10. Adjust the synchronization interval manually
