Alarm Didn’t Go Off on Android? 8 Best Ways to Fix it

The alarm clock of Android may fail to work for various reasons, mainly due to incorrect date & time settings and problematic app files. Below are some of the best ways to fix Alarm didn’t go off on Android issue.

1. Restart your Android Phone

The first thing you should do if Alarm is not ringing on your Android is restart your smartphone. Restarting will possibly eliminate all apps & processes that may prevent the Alarm from functioning properly.

In addition to that, restarting also clears the RAM. To restart your Android phone, long press on the Power Menu and select Restart. After the restart, set the Alarm again.

2. Check the Alarm Volume and Ringtone

Check the Alarm Volume and Ringtone

The latest versions of Android allow users to control the volume of alarms. By default, the Alarm is set to go off even when the phone is silent.

However, you may have accidentally lowered the volume level; hence, the Alarm is going off, but you cannot hear it.

Even if the Alarm Volume is high, check the Alarm tune. If you are a heavy sleeper, you can pick an Alarm tune that’s louder. The option to control the volume level depends on your phone.

Usually, you can control the volume for Media, Ringtone, Notification, Alarms, etc, through the Volume Slider that appears after pressing the physical volume button of your phone. So, press the volume key of your phone and set the volume slider for Alarms to maximum.

3. Check your phone’s Do Not Disturb Settings

Do Not Disturb mode of Android is designed to provide a distraction-free experience by silencing all sounds. Generally, the DND mode doesn’t change the settings for Alarm, but there’s still an option to silence the Alarms.

If you are using a third-party Alarm clock app for Android, DND mode is likely preventing it from ringing your device. So, it’s important to check the exceptions list of DND mode.

1. Open the Settings app on your Android smartphone.

2. When the Settings app opens, tap on the Sound & vibration.

4. Check the Clock Alerts on your Phone

On selected Android smartphones, there’s an option known as Clock Alerts or Notification Alerts that lets users silence alarms when the system sound is off.

If this feature is enabled on your smartphone, the Alarms will vibrate instead of making sound when your phone is in silent mode or Vibrate.

You will usually find this option in the Apps > Clock > Clock Settings. On the Clock Settings, look at the Alerts section and turn off the ‘Silence alarms when system sound is off’ toggle.

The steps to find this option may vary depending on your phone skin. You can also check the Notification settings of your Smartphone to find the ‘Silence alarms when system sound is off’ option.
