1. Cause and symptoms of alarm failure
Problems with the alarm not ringing or no sound can occur in the following symptoms.
Alarm does not sound at the set time
Alarm window appears but no sound
Only vibrate, no sound heard
Repeated alarms do not work, or only on certain days of the week
Key causes:
Alarm app settings or volume/silence mode problems
App unauthorized, sleep/battery optimization impact
Sound file error, alarm app itself bug
Not applying system updates
2. Fixing problems quickly
Check Alarm and Volume Settings
When the alarm doesn’t go off, be sure to check the alarm time, iteration, vibration, sound type, and volume setting of the alarm app first.
Check the alarm app to see if the alarm is in the ‘on’ state
Check that the alarm sound is not set to ‘none’
Press the Volume button to raise the ‘Alarm/Media Volume’ sufficiently
Silent/Do Not Disturb Mode Off
If silent, vibrating, and do not disturb (DND) mode is turned on, the alarm may not sound. Release the mode from the status bar, quick setting window, etc.
3. Check alarm and sound settings
Setting App Permissions and Battery Optimization Exception
Some smartphones can force alarm apps to shut down with power saving/battery optimization. Register the alarm app as a ‘battery optimization exception’ and grant them background execution rights.
Settings > Apps > Alarms Apps > Batteries > Disable Battery Use Optimization
Allow mandatory permissions, such as ‘alarm’ and ‘background execution’ from the permissions menu
Alarm sound file/app error check
The sound file may be corrupted, or it could be an error in the app itself. Change it to a different default sound, or update the alarm app to the latest version.
4. Advanced and additional troubleshooting methods
Apply latest updates to systems/apps
Keeping the OS and alarm apps up to date can prevent the alarm from running due to compatibility issues and bugs.
Reboot and Factory Initialization of Devices
Temporary errors can be resolved by rebooting, and if the problem persists after trying all the methods, consider factory initialization after backup.
Use a different alarm app
If you have a problem with your default alarm app, you can try out a trusted third-party alarm app on Google Play, etc.
