Many people rely on their phone alarms to wake them up in the morning, remind them of important events, or alert them of potential dangers. However, there is some confusion about whether alarms function when a phone is on silent or Do Not Disturb (DND) mode. While silent mode simply mutes calls, notifications, and alerts, DND mode is more complex. DND mode can silence calls, text messages, and app alerts, but it does not always affect alarms. The functionality depends on the phone's settings, the type of DND mode, and the alarm app being used. Some phones may offer exceptions to allow alarm sounds in DND mode, and certain alarm apps may not override DND settings. To ensure an alarm sounds on a phone in DND mode, users should check their phone settings and confirm that the alarm is properly set up with the correct time, date, and ringtone.

What You'll Learn

Alarms on iPhone will sound in DND mode
If you have an iPhone and are worried that your alarm won't sound if your phone is on Do Not Disturb (DND) mode, you can rest assured that your iPhone's alarm will still go off when your phone is on Do Not Disturb. However, it is important to make sure that your alarm is set up correctly.
Firstly, you should check that your alarm is turned on. You can do this by opening the Clock app and tapping on "Alarm" at the bottom of the screen. Make sure your desired alarm is turned on by sliding its button to the right. Double-check the time of the alarm, paying particular attention to whether you've selected AM or PM.
Secondly, ensure that you have selected an alarm tone. If you have set the alarm tone to 'None', your iPhone will only vibrate instead of sounding your alarm. To select an alarm tone, tap “Edit” at the top left of the screen, then tap the alarm you want to check. Tap a sound to hear a preview, then tap “Back” once you've chosen your preferred sound.
Additionally, you should check that the volume on your iPhone is set loud enough to wake you up. You can adjust the volume using the physical volume buttons on the side of your iPhone or by going to Settings > Sounds & Haptics and dragging the slider under Ringtone and Alerts.
If you have followed these steps and your alarm still doesn't sound when your phone is on DND, it could be due to software glitches or issues. Try restarting your iPhone to resolve temporary issues and ensure the alarm works as intended.

Alarms on Android may not sound in DND mode
Alarms on Android devices may not sound when Do Not Disturb (DND) mode is enabled, depending on your settings. DND mode is a feature that allows users to silence incoming calls, messages, and notifications to prevent interruptions and distractions. However, it is important to note that some Android devices may offer exceptions to allow alarm sounds in DND mode.
To ensure your alarms function as expected on your Android device, follow these general steps:
- Open the "Settings" app on your device.
- Scroll down and select "Sound & vibration," "Sound," or a similar option (menu labels can vary).
- Look for the "Do Not Disturb" or "DND" settings.
- Within the DND settings, find the option related to alarms.
- Ensure that alarms are allowed or exempted from DND restrictions.
By following these steps, you can enable or disable DND mode on your Android device while ensuring that your alarms work as intended. It is worth noting that the steps to enable or disable DND mode may vary slightly depending on your device manufacturer and Android version.
Additionally, Android devices offer a ""Total silence" mode under "Do Not Disturb," which blocks all notifications and silences all sounds, including alarms. Therefore, it is crucial to review your DND settings and ensure that alarms are allowed to sound while DND mode is active.

Alarms on Google Pixel may not sound in DND mode
If you have a Google Pixel phone, you may have experienced a situation where your alarm didn't sound when your phone was in Do Not Disturb (DND) mode. This issue has been reported by several users on online forums.
It's important to note that the behaviour of alarms in DND mode may vary depending on your phone's settings and the apps you use. In some cases, the alarm may not sound if DND is turned on. This could be due to certain settings or interactions with other features, such as the vibrate or mute switch.
To ensure your alarm sounds even in DND mode, you can adjust your settings. Firstly, long-press the DND quick settings tile and check the alarms toggle inside "Alarms & other interruptions". Make sure that alarms are enabled in this menu. Additionally, it is recommended to use the built-in Clock app, as third-party alarm apps may not override the DND mode.
Another workaround is to schedule the DND function to turn off right before your alarm is set to go off. This way, you can ensure that your phone is in silent mode during the night, but the alarm will still sound at the designated time.
It's worth mentioning that some users have reported instances where their alarms didn't sound even with the correct settings. In such cases, it is advised to check your volume settings, reset your device, or force-close and reopen the Clock app.

Alarms on iOS will sound in DND mode
If you're concerned that your iPhone's alarm won't sound when you're on Do Not Disturb, there's no need to worry—your alarm will still ring in Do Not Disturb mode. Do Not Disturb silences phone calls, text messages, and other notifications, but it does not affect your alarms.
To make sure your alarm will sound, check that the alarm is turned on and a ringtone is selected. Here's how you can do that:
- Start the Clock app and then tap on "Alarm" at the bottom of the screen.
- Make sure your desired alarm is turned on by sliding its button to the right.
- Ensure your alarm is turned on or it won't ring.
- Double-check the time of the alarm, paying particular care that the correct AM or PM setting is selected.
- Tap "Edit" at the top left of the screen and then tap the alarm you want to check.
- Select the sound you want to use for the alarm — make sure you can hear it play — and then tap "Back." Be sure you have a ringtone selected, so the alarm will sound.
Your alarm is now configured and will go off at the selected time, on the selected days, even in Do Not Disturb mode.
It's important to note that if you download and install a third-party alarm app, it may not override DND. However, if you use the built-in Clock app in iOS, it will override DND, and your alarm will sound as expected.

Alarms on other phones may not sound in DND mode
When it comes to smartphone alarms and their functionality in Do Not Disturb (DND) mode, it's important to note that the behavior may vary depending on the phone model and its settings. While some phones may allow alarms to sound in DND mode, others may not.
In the case of Google Pixel phones, for instance, there have been reports of alarms not sounding when the phone is in DND mode. Users have discovered that the alarms were inadvertently turned off in the DND settings, causing the issue. To resolve this, users can long-press the DND quick settings tile and ensure that the alarms toggle inside "Alarms & Other Interruptions" is enabled.
For iOS devices, the behavior depends on the type of alarm app being used. If you use the built-in Clock app, the alarm will override DND and sound as expected. However, if you use a third-party alarm app, such as "Alarm 4 Free" from Impala Studios, the alarm may not override DND, and you might need to schedule the DND function to turn off before the alarm time.
It's worth mentioning that Silent Mode and Airplane Mode on smartphones generally do not affect the functionality of alarms. Unless specific settings are adjusted, you can expect your alarms to sound even when your phone is in these modes.
To ensure that your alarms function as intended on any phone, it is recommended to check the device's settings and confirm that alarms are exempted from being silenced in DND mode. This way, you can trust that your alarms will go off as scheduled, even with DND enabled.
