Your phone is silencing notifications because you've turned on Do Not Disturb, Focus mode, or a similar feature—or because an app's own settings are muting it

Notifications disappear for one of three reasons: a system-wide setting on your phone is blocking them, a specific app has its own mute switch turned on, or your phone's volume is set too low for that notification type. The most common culprit is Do Not Disturb (on iPhone) or Do Not Disturb (on Android), which silences everything except calls and messages from people you've marked as favorites. Focus modes on newer iPhones work the same way—they block notifications by category until you turn them off.

The second reason is less obvious: you may have muted an individual app without realizing it. On both iPhone and Android, you can silence notifications from a single app while leaving everything else on. This happens when you swipe down on a notification and tap "Manage" or "Settings," then toggle off notifications for that app. The third reason is volume—your phone's notification volume might be turned down separately from your call volume, so notifications play silently even though your ringer is on.

Key Takeaways

  • Check whether Do Not Disturb or Focus mode is active on your phone—these block most notifications until you turn them off manually.
  • Open your phone's Settings and search for the specific app name to see whether that app's notifications are muted in its own settings.
  • Make sure your notification volume is turned up separately from your call volume, since phones often control these independently.
  • Some notifications (like calendar reminders or low battery alerts) have their own on/off switches buried in each app's settings, not in your phone's main notification panel.

How to check Do Not Disturb and Focus modes on iPhone

Swipe down from the top-right corner of your screen to open Control Center. Look for the Do Not Disturb icon (a circle with a line through it) or any Focus mode that's highlighted in color. If either one is on, tap it to turn it off. Do Not Disturb silences calls, texts, and alerts; Focus modes are more selective and let you choose which apps can notify you.

If you see a Focus mode active, you can either tap it to turn it off entirely, or tap and hold it to see which apps are allowed to send notifications while that Focus is on. Some people set up Focus modes for work, sleep, or driving and forget to turn them off—that's why notifications vanish even though you didn't intentionally silence them.

How to check Do Not Disturb and Focus modes on Android

Swipe down twice from the top of your screen to open the full Quick Settings panel. Look for Do Not Disturb or Interruption filters (the name varies by phone maker). If it's on, tap it to turn it off. On Samsung phones, this setting may be called Do Not Disturb or Bedtime mode; on Google Pixels, it's usually Do Not Disturb.

Some Android phones also have a Notification shade setting that lets you hide notifications from appearing on your lock screen or in your notification panel without actually silencing them. This won't stop the notification from arriving, but it will hide it from view—so you might think notifications are silenced when they're actually just hidden.

Muting notifications from a single app

If notifications from one specific app have disappeared, that app's notifications are probably turned off. On iPhone, go to Settings, scroll down to find the app name, tap it, and look for Notifications. If it says "Allow Notifications" and the toggle is off, turn it on. You can also choose whether notifications appear on your lock screen, in your notification center, or as banners.

On Android, go to Settings, tap Apps or process Manager, find the app, tap Notifications, and make sure notifications are turned on. Some Android phones let you swipe left or right on a notification to reveal a settings icon—tapping that takes you straight to that app's notification settings.

If you've turned notifications back on but they're still silent, check the app's own internal settings. Open the app itself and look for a Settings or Preferences menu. Some apps (like Gmail, Slack, or calendar apps) have their own notification controls separate from your phone's system settings. You may need to turn notifications on both in your phone's settings and inside the app.

Checking your notification volume separately from your call volume

Your phone may have separate volume controls for calls, notifications, and media. On iPhone, go to Settings, tap Sounds & Haptics, and look at the volume slider under "Ringer and Alerts." Make sure it's not all the way down. You can also toggle Change with Buttons on or off—if it's on, you can use your physical volume buttons to adjust notification volume.

On Android, press one of your physical volume buttons, and a volume slider will appear on screen. It usually shows the current volume type (call, notification, or media). Tap the three dots or settings icon on that slider to see all volume types and adjust each one separately. Make sure notification volume is turned up.

Finding muted notifications in your notification settings

Some notifications are silenced by their own app settings, not by your phone's system settings. Calendar reminders, email alerts, and low battery warnings often have individual on/off switches. Open the app, go to its Settings or Preferences, and search for "Notifications" or "Alerts." Turn on any notification types you want to see.

On iPhone, you can also go to Settings, tap Notifications, and scroll through the list of all apps. Any app with notifications turned off will show "Allow Notifications" as off. On Android, go to Settings, tap Apps, and look for a Notifications section that shows which apps have notifications disabled.

Why notifications might be silenced even when Do Not Disturb is off

If Do Not Disturb is off and the app's notifications are turned on, but you're still not seeing alerts, check whether your phone is in Silent mode. On iPhone, look for the physical mute switch on the left side of the phone—if it's flipped toward the back, your phone is in silent mode and won't play notification sounds. Flip it forward to turn sound back on.

On Android, your phone doesn't have a physical mute switch, but you can check your volume settings by pressing a volume button and making sure the notification volume slider is not all the way down. Also check whether your phone's Vibration setting is on—some phones vibrate for notifications even when sound is off, so you might not hear them but you should feel them.

Frequently Asked Questions

Why do some notifications come through even when Do Not Disturb is on?

Do Not Disturb usually allows calls and messages from your favorites or recent contacts to come through, depending on how you set it up. On iPhone, you can customize which people and apps bypass Do Not Disturb by going to Settings, tapping Focus (or Do Not Disturb, depending on your iOS version), and adjusting "Allow Calls From" and "Allow Messages From."

Can I turn off notifications for just one type of alert, like email, but keep others on?

Yes. Open the app (like Gmail or Outlook), go to its Settings or Preferences, find the Notifications section, and turn off only the notification types you don't want. You can usually choose to mute email notifications but keep calendar reminders, for example. On your phone's system level, you can also go to the app's notification settings and toggle off specific notification categories.

My notifications are on, but I never hear them—what else could be wrong?

Check your phone's overall volume by pressing a volume button and looking at the slider. Make sure the notification volume (not just call volume) is turned up. Also check whether your phone is in silent mode—on iPhone, flip the mute switch on the left side of the phone forward. If notifications are still silent, restart your phone, which often fixes notification sound issues.

Why did my notifications suddenly stop working after an update?

Phone updates sometimes reset notification settings or turn on Do Not Disturb by default. Check your Do Not Disturb and Focus settings first. If those are off, go to Settings and search for the app name to make sure its notifications are still turned on. You may also need to restart your phone or reinstall the app if notifications remain silent.

How do I know if an app has its own notification mute switch I don't know about?

Open the app and look for Settings, Preferences, or a gear icon. Search for "Notifications," "Alerts," or "Sound." If you find a section with notification options, check whether each type is turned on. Some apps hide notification settings deep in their menus, so if you don't find them in the main settings, try looking under "Advanced" or "Privacy."
