Does “Do Not Disturb” block alarms on iPhone and Android? Well, whether you’re using an Android or iPhone device, the “Do Not Disturb” mode is designed to block any incoming notifications, calls, and alerts while still allowing some exceptions. In this discussion, you’ll learn how the “Do Not Disturb” mode operates on Android and iPhone devices and whether it can affect the critical functions of your alarm system. Understanding this feature is very important when it comes to managing your device’s notifications while at the same time making sure you don’t miss your critical reminders and wake-up calls.

Alarms are generally considered one of those exceptions, so they should still go off even when your phone is in “Do Not Disturb” mode.

Why didn’t my alarm go off?

Moreover, it could be that you’ve customized the settings to allow alarms; this could also explain why your alarm didn’t go off. It’s essential to check your device’s “Do Not Disturb” settings and ensure that your alarm is allowed in this mode. Other potential reasons could be a low battery, a malfunctioning alarm app, or other device issues.
