Fixing Push Notifications on the HONOR devices
The following guide is based on the official vendor recommendations. You can find more information via the following link: https://www.hihonor.com/uk/support/content/en-us00685514/
If you can't receive notifications for new messages from a third-party app running in the background, or after the phone screen has been turned off for a while, refer to the following for troubleshooting.
If you cannot receive messages after powering on or restarting your phone, this is normal. This is because the app has not started after the phone was restarted. Touch the app icon to start the app and receive messages.
1. Check for updates
Go to Google Play Store or the app's official website to update the app to the latest version.
Check for updates for your phone:
Open Settings, search for and access Software update or System update, and touch Check for updates. If a version is available, update your phone at your earliest convenience.
2. Enable app notifications
Enable the notification permission
Go to Settings > Notifications, find the app in question, enable Allow notifications, and enable Allow notifications, Display in status bar, Banners, and Lock screen notifications as required.
Enable notifications in the app.
Go to the app settings and enable notifications.
Please note, Ringotel will not immediately push messages to the registered mobile devices if you have logged in to the PC-based version of the app.
3. Check the network connection
Disable Data saver.
You will not be able to receive notifications from an app if the network connection permission of the app is disabled, or you have enabled Data saver for the app.
Open Phone Manager, go to Mobile data > Networked apps, find the app in question, and enable at least one of Mobile data and Wi-Fi.
Open Phone Manager, go to Mobile data > Data saver (Smart data saver), and disable Data saver (Smart data saver). Alternatively, you can keep Data saver (Smart data saver) enabled, locate the app in the EXEMPTIONS list, and turn on the switch next to it.
Enable Wi-Fi/Mobile data switch and Stay connected when device sleeps.
It may be because no Wi-Fi connection is available and your phone has not automatically switched to the mobile data network, or your phone has disconnected from the network during sleep.
Enable Stay connected when device sleeps.
Magic UI 4.0/4.2/5.0: Open Settings, search for and access Stay connected when device sleeps, and enable this feature.
4. Enable the permission for the app to run in the background
If an app is forbidden from running in the background or cleared from the background, there will be no notifications from this app.
Allow the app to start automatically and run in the background.
Go to Optimizer > % remaining > App launch, find the app in question, disable Manage automatically, and enable Auto-launch, Secondary launch, and Run in background.
Lock the app on the recent tasks screen:
Magic UI 4.0/4.2: Open the background apps running screen, find the app in question, and swipe down on the app card. If a lock icon is displayed in the upper right corner of the app, it indicates that the app is locked. To unlock the app, swipe down again.
5. Disable the battery optimization functions
You may have closed the app when your phone displays a Power consumption alert. If this is the case, ignore the Power consumption alert for the app to continue running on your phone.
Disable Power saving mode or Ultra power saving mode.
Go to Settings > Battery, then disable Power saving mode or Ultra power saving mode.
Allow Ignore battery optimization.
Magic UI 4.0/4.2/5.0 : Open Settings, search for and access Battery optimization, touch the triangle icon, select All apps, find the app in question, and set it to Don't allow.

Enable Smart tune-up in Phone Manager, and clear data of Phone Manager by performing the following:
Open Phone Manager, touch  in the upper right corner, and enable Smart tune-up.
Open Settings and search for Apps. Locate and touch Phone Manager, then go to Storage > CLEAR DATA. Ensure your phone is connected to the network, then open Phone Manager. Wait until Phone Manager displays a score on its screen and restart your phone.
The preceding operation will restore all the other settings for Phone Manager. It is advised that you configure the settings again afterwards.
7. Uninstall and re-install the app
Uninstall any third-party phone managers.
Third-party management apps may manage your apps according to their own rules. Check whether a third-party phone manager app is installed on your phone. If so, uninstall it or add the app to the list of trusted apps in the third-party phone manager app.
Uninstall the app and install it again.
