How to Fix Do Not Disturb Not Working on Your Phone
2026-10-14 · Marion Phone Repair
You turned on Do Not Disturb expecting silence, but your phone keeps ringing, buzzing, or lighting up with notifications. DND is supposed to block calls, texts, and app alerts — but it has exceptions built into it, and those exceptions are the reason it appears broken. The fix is almost always a settings issue, not a software bug.
How Do Not Disturb actually works
Do Not Disturb does not block everything by default on either iPhone or Android. It blocks notifications from appearing on screen and silences most calls and messages, but it has built-in exceptions for contacts marked as favorites, repeat callers, and alarms. Understanding what DND does and does not block is the first step to fixing it.
iPhone DND and Focus modes
Starting with iOS 15, Apple replaced the single Do Not Disturb toggle with Focus modes. DND is now one of several Focus modes (Do Not Disturb, Sleep, Work, Personal, etc.). Each Focus mode has its own list of allowed people and allowed apps. If you set up DND and notifications are still coming through, it is because those contacts or apps are on the allowed list for your current Focus mode.
Android DND
Android's Do Not Disturb has three levels: Total silence (blocks everything including alarms), Alarms only (blocks everything except alarms), and Priority only (allows calls and messages from starred contacts, repeat callers, and reminders). Most Android phones default to Priority only, which lets a lot through.
Check your allowed contacts and apps (most common cause)
iPhone
Open Settings, then Focus, then Do Not Disturb
Look at Allowed Notifications. Under People, check who is listed — anyone here can call or message you even with DND on. Remove contacts you do not want to hear from during DND
Under Apps, check which apps are allowed. Apps listed here will send notifications through DND. Remove any you do not need
Check the Calls From setting under People. If it is set to Favorites, Everyone, or a specific contact group, those calls will ring through. Set it to No One if you want complete silence
Android
Open Settings, then Sound and vibration (or Notifications on some brands), then Do Not Disturb
Tap People (or Priority only allows). Check Calls — if it says From starred contacts or From anyone, those calls will ring through DND. Change to None if you want no calls
Check Messages — same logic applies. Set to None to block all message notifications
Check Alarms and other interruptions. Reminders, events, and media sounds may be allowed by default
Repeat callers exception
Both iPhone and Android have a repeat callers feature that lets a call through if the same person calls twice within 3 minutes (iPhone) or 15 minutes (Android). The idea is that someone calling repeatedly might have an emergency. This feature catches many people off guard — they get a second call from a telemarketer or work contact and assume DND is broken.
iPhone: Settings, Focus, Do Not Disturb, People. Toggle off Allow Repeated Calls
Android: Settings, Sound and vibration, Do Not Disturb, People, Calls. Toggle off Allow repeat callers
Scheduled DND not activating or deactivating
If DND is supposed to turn on automatically at a certain time but does not:
iPhone: Go to Settings, Focus, Do Not Disturb, and check your Schedule. Make sure the schedule is toggled on and the times are correct. If you have a Bedtime schedule under the Sleep Focus mode, it may conflict with your DND schedule — these are separate Focus modes and only one can be active at a time
Android: Go to Settings, Sound and vibration, Do Not Disturb, Schedules. Make sure your schedule is toggled on. Check that the days are correct — a schedule set for weekdays will not activate on weekends. Samsung phones have a separate Bedtime mode in Digital Wellbeing that can conflict with DND schedules
Alarms still sounding during DND
This is intentional — alarms bypass DND on both iPhone and Android by default so you do not sleep through your alarm. If you need absolute silence (no alarms either), you need to either delete or disable the alarm separately, or on Android, use Total silence mode instead of Priority only.
Specific apps still sending notifications
Some apps have their own notification priority settings that can override DND:
iPhone: Some apps use Time Sensitive notifications, which are designed to break through Focus modes. Go to Settings, Notifications, find the app, and toggle off Time Sensitive Notifications if you do not want it to override DND
Android: Some apps set their notifications as high priority or use foreground services (like navigation or music players) that bypass DND. Go to Settings, Apps, select the app, then Notifications, and set its notification channels to Silent or turn them off
Emergency alerts: Government emergency alerts (AMBER alerts, severe weather) bypass DND on both platforms. On iPhone, go to Settings, Notifications, scroll to the bottom to toggle off Emergency Alerts. On Android, open the Messages app, Settings, Emergency alert settings
DND icon is on but phone still rings
If the DND moon icon (iPhone) or DND circle icon (Android) shows in the status bar but calls still ring through:
Check your ringer switch: On iPhone, make sure the physical ring/silent switch on the left side is set correctly. DND and the silent switch are independent — you may need both
Connected devices: If your phone is connected to a Bluetooth speaker, car stereo, or smartwatch, calls may ring on those devices even with DND on. DND on your phone does not automatically silence connected devices — your smartwatch may have its own DND toggle
CarPlay and Android Auto: Calls come through the car speakers regardless of DND because the car system manages audio routing independently. You need to enable DND on the car system separately
Reset DND settings
If DND still does not work after checking all the above:
iPhone: Delete the Do Not Disturb Focus and recreate it. Go to Settings, Focus, Do Not Disturb, scroll down, and tap Delete Focus. Then go back to Focus and add it again. This resets all its allowed contacts, apps, and schedules to defaults
Android: Go to Settings, Sound and vibration, Do Not Disturb, and manually set every category (People, Apps, Alarms) to block everything. Then toggle DND off and on. If this does not help, go to Settings, General management (or System), Reset, Reset all settings. This resets sound, display, and network settings without deleting data
