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

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.

   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.

   Open Settings, search for and access Apps, find the app, go to Permissions > View all permissions, and enable run at startup.

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 your device is powered on below for further troubleshooting.

Adjust the alarm ringtone:

Go to Settings > Sound/Sounds & vibration and drag the slider to adjust the alarm volume. Check whether the ringtone file can be played properly. If not, switch to a different ringtone.

Clear the cache:

Open Settings, search for and access Apps, find Clock, and go to Storage > CLEAR CACHE. Then, Add the Alarms again.

Allow alarms to ring when the phone is powered off: After setting an alarm clock, press and hold the Power button to display the power-off/restart screen. Tap Power off, select Keep alarms active, and tap Power off.

Check whether your device is connected to a HUAWEI watch. If so, restart the watch and try again.
