General Tips

On mobile devices, the system may block or restrict the background operation of the app. In that case, notifications and incoming calls stop arriving. This guide will help restore them if the app is unloaded from memory and doesn't run in the background.

General Recommendations for Android

1. Make sure the app has permission to show notifications: Settings > Apps > select the app > Notifications > enable the permission.
   Starting with Android 13, showing notifications is a separate permission (POST_NOTIFICATIONS). For a newly installed app, notifications are disabled by default until the user allows them.
2. Exclude the app from standard power-saving features.
3. Disable background data saving or add the app to the exceptions for background data transfer.
4. Disable automatic suspension of unused apps: Settings > Apps > select the app > turn off Pause app activity if unused.
   If this option is enabled, after several months of inactivity the system revokes the app's permissions, clears temporary files, and stops its background activity and notifications.
5. Still not receiving notifications? Collect diagnostics and contact Support: Support will check which notification service is running on the device. Install the app from another store only if support advises it.
   When installing from a store other than Google Play, background activity must be allowed not only for the app itself but also for the store: RuStore or AppGallery together with HMS Core. Without this, push notifications arrive with a delay.
   In the app from RuStore, notifications arrive only through the RuStore service. The manufacturer does not embed RuStore in Android, so the system restricts it in the background more strictly than Google services. For notifications to arrive reliably, complete all the steps of this guide for both the app and RuStore. Open the app at least once every two days: if you do not open it for longer, the system stops the app.
6. Pin the app in the recent list to prevent it from being unloaded from memory.
7. Exclude the app from third-party optimizations or disable optimizations entirely.
8. Disable restrictions in manufacturer-provided optimizer apps or uninstall them.
9. Make sure the app is not blocked by Do Not Disturb or Focus (Digital Wellbeing) modes, and add it to the exceptions for these modes.

Notes

• The paths to settings may differ even among different models from the same manufacturer.
• After an OS update or device reboot, exception settings are sometimes reset. In this case, restore them manually.
• If the device is enrolled in a mobile device management (MDM) system or the app is installed in an Android Enterprise work profile, some of the listed settings may be unavailable to the user. Such settings are defined by administrator policies. In this case, contact your organization's system administrator or support team.

Android 13–16 Restrictions

Besides manufacturer optimizations, every new Android version adds its own app restrictions. They apply to devices from any vendor.
