The alarm does not go off as scheduled or there is no alert tone on my HUAWEI phone/tablet

If you are using a third-party alarm app:

If the app is not allowed to run in the background, or is cleared from the background, it will not schedule an alarm. To resolve this issue, perform the following:

1. Allow the app to start automatically and run in the background.

   • Open Settings, search for and access Launch, turn off the switch next to the app, and enable Auto-launch, Secondary launch, and Run in background.

2. Lock the app on the Recent tasks screen.

   HarmonyOS, EMUI 9.X, and Magic UI 2.X, or later: Go to the Recent tasks screen, select the app, and swipe down on the app preview screen. If a lock icon displays in the upper right corner on it, the app is locked.

3. Enable the app to run at startup.

   HarmonyOS, EMUI 9.X, and Magic UI 2.X, or later: Open Settings, search for and touch Apps, and find the app. Then, go to Permissions > View all permissions, and enable run at startup.

If the alarm does not ring in Sub-user or Guest mode:

1. If alarms set by a sub-user or guest do not ring after a restart:

   By default, your phone will switch to Owner mode after a restart, and alarms set by any sub-user or guest will not ring.

2. If alarms do not ring after switching to another sub-user:

   When multiple sub-users have been added, only the alarms set by the owner and the last sub-user to use the device will be scheduled to ring. Alarms set by other sub-users will not ring.

3. If alarms do not ring after exiting Guest mode:

   Alarms set by a guest will not ring in Owner or Sub-user mode. It is recommended that you set alarms in Owner mode.

4. If your case is not listed above, refer to If the alarm does not ring when it goes off and phone is powered on below for further troubleshooting.
