1. Check your phone's battery
If your phone runs out of battery, all activities cease, including the alarm. Ensure your phone is fully charged at the set alarm time for it to function accurately.

2. Verify the alarm ringtone volume settings
If you can't hear the alarm, check the ringtone volume. For iPhone, go to Clock app > Edit > choose alarm > Sound > select sound > Back > Save. For Android, adjust in Clock app > Alarm > Sound.
- 3. Update the operating system for your phone

3. Update the operating system for your phone
Alarm malfunction can also stem from an outdated smartphone operating system. Therefore, upgrading your phone's software is an effective troubleshooting method:
For iPhone and iPad: Open Settings > select General Settings > choose the Software Update > select Download and Install
For Android phones: Open Settings > select Software Update > press Download and Install

If there is a new operating system update, the device will automatically download and install it. However, if your phone is already upgraded to the latest version, you will receive the notification “Your software has been updated”
4. Use only one default alarm app
Using too many alarm apps may not only fail to wake you up on time but also lead to alarm malfunctions. It is most effective to use the default alarm app on your phone. If you prefer a third-party alarm app, you should completely disable the default app

5. Check if the alarm is activated and set correctly
Sometimes, due to sleepiness or forgetfulness, failing to activate or set the alarm at the right time can result in not hearing the phone ring. Make sure to double-check that you have set the alarm correctly and activated the alarm sound

6. Restart your phone
Restarting your phone is a simple and effective troubleshooting method, especially for minor issues, including alarm malfunctions. Give this method a try to see if the alarm sound starts working again.

7. Reset phone settings
And finally, if you have tried the above methods without success, consider resetting your phone settings (or performing a factory reset) following the instructions below:
For iPhone and iPad: Open Settings > select General Settings > choose Reset > select Reset All Settings > enter your password, and the system will reset the settings for the iPhone to the original factory settings
For Android phones: Open Settings > select General Management > press Reset > select Factory Data Reset and press again on Reset Settings
