Many smartphone users often ask, “do alarms go off on dnd?” The simple answer is yes. On most Android and iPhone devices, alarms will still ring even when Do Not Disturb mode is enabled. DND mainly blocks calls, notifications, messages, and app alerts, but it does not stop your alarm clock from working. This feature helps users sleep peacefully without missing important wake-up alarms. However, custom device settings can sometimes affect alarm behavior, so it is always a good idea to test your alarm before relying on it for important schedules or meetings.
