Notifications stop showing for four main reasons: your phone's focus mode is on, the app permission is turned off, the notification channel is muted, or your phone's Do Not Disturb is active
Most missing notifications are not a mystery — they are sitting in your notification center, just not making a sound or lighting up your screen. Your phone is doing exactly what you told it to do, even if you do not remember telling it. The fastest way to find them is to swipe down from the top of your screen (on Android) or down from the top right (on iPhone) and look for a notification center full of messages you never saw arrive.
If nothing is there at all, the notification never reached your phone. That means either the app does not have permission to send them, or you have silenced them at the system level. Both are fixable in under a minute.
Key Takeaways
- Check your phone's notification center first by swiping down from the top — many notifications are there but silent, not actually missing.
- On iPhone, Focus modes (like Work or Sleep) block notifications from apps you did not whitelist, even if the app itself has permission.
- On Android, notification channels let you silence one app without turning off all notifications, and you may have muted a channel by accident.
- Do Not Disturb and Focus modes are the most common culprits because they silence notifications system-wide while leaving app permissions untouched.
- If an app has no notification permission at all, you will not see anything — check Settings and turn the permission back on for that specific app.
Check your notification center before assuming they are gone
Notifications that arrive while your phone is locked or while you are using another app go to your notification center. They sit there silently until you look for them. On iPhone, swipe down from the top right corner of your screen. On Android, swipe down from the top. You will see a list of everything that came in, even if you heard nothing and saw no badge.
If you find the notification you were looking for, the problem is not that it did not arrive — it is that your phone is not alerting you to it. That is a sound, vibration, or banner setting, not a permission problem. On iPhone, go to Settings > Notifications > [App Name] and turn on "Allow Notifications" if it is off, then check the "Sounds" toggle. On Android, go to Settings > Apps > [App Name] > Notifications and make sure "Show Notifications" is on.
Turn off Focus modes on iPhone that are blocking the app
Focus modes on iPhone (Work, Sleep, Driving, Custom) let you silence most notifications while allowing calls and messages from specific people. If you turned on a Focus mode and did not add an app to the allowed list, that app will not notify you at all — even if notifications are on in Settings. The notification arrives, but your phone blocks it from reaching you.
Check which Focus mode is active by swiping down from the top right and looking at the top of Control Center. If a Focus mode is on, tap it and look at the list of allowed apps. If the app you need is not there, tap "Allow Notifications from" and add it. If you do not want the Focus mode on at all, tap it again to turn it off. You can also go to Settings > Focus and turn off the mode entirely.
Check notification channels on Android for a muted setting
Android lets you control notifications at two levels: the app itself, and the notification channel within that app. A channel is a category — for example, Gmail has separate channels for inbox notifications and promotional emails. If you muted one channel, only that type of notification will be silent. You may have done this by accident by long-pressing a notification and choosing "Don't show these notifications."
To fix it, go to Settings > Apps > [App Name] > Notifications. You will see a list of channels. If one says "Muted" or has a muted icon next to it, tap it and turn the sound back on. If all channels are muted, turn on "Show Notifications" at the top of the screen. You can also long-press a notification from that app and choose "Show notifications" to unmute it when ready.
Turn off Do Not Disturb and check your phone's system settings
Do Not Disturb silences all notifications except calls and messages from your favorites. It is straightforward to turn on by accident — on iPhone, swipe down from the top right and tap the moon icon. On Android, swipe down twice and look for "Do Not Disturb." If it is on, tap it to turn it off. Some phones also have a "Priority Only" mode that works the same way.
While you are in your phone's settings, check that notifications are turned on at the system level. On iPhone, go to Settings > Notifications and make sure "Allow Notifications" is on. On Android, go to Settings > Apps > Permissions > Notifications and make sure the app has permission. If the permission is off, tap it and turn it on.
Give the app permission to send notifications in the first place
If you never see a notification from an app, even in your notification center, the app probably does not have permission to send them. This happens when you first install an app and deny the notification request, or when you turn off the permission later in Settings. The app cannot send notifications without this permission — it is a system-level block.
Go to Settings > Apps > [App Name] > Permissions and look for "Notifications." If it says "Not allowed" or is toggled off, tap it and turn it on. On iPhone, go to Settings > Notifications > [App Name] and make sure "Allow Notifications" is on. The next time the app tries to send something, it will reach you.
Check if the app itself has notification settings you turned off
Some apps have their own notification settings inside the app, separate from your phone's settings. You might have turned off notifications in the app itself without realizing it affects what your phone receives. Open the app, go to Settings or Preferences (usually a gear icon), and look for a Notifications section. Make sure notifications are turned on there as well.
For example, Gmail has notification settings in the app, Slack has notification preferences in the workspace settings, and Discord has notification settings per server. If the app's internal setting is off, your phone will never see the notification to deliver it, even if your phone's permission is on.
Frequently Asked Questions
Why do I see some notifications but not others from the same app?
The app likely has multiple notification channels, and you muted one of them. On Android, go to Settings > Apps > [App Name] > Notifications and check each channel. On iPhone, check if a Focus mode is blocking certain types of notifications. Some apps also let you turn off notifications for specific categories in their own settings.
My notifications were working yesterday but stopped today. What changed?
You probably turned on a Focus mode, Do Not Disturb, or a battery saver mode without realizing it. Check Control Center on iPhone or the quick settings on Android. You may also have accidentally muted a notification channel by long-pressing a notification. Check your phone's notification settings and the app's settings to see what changed.
Can I get notifications from one app but not others?
Yes. You can turn off notifications for specific apps in Settings while leaving them on for others. On iPhone, go to Settings > Notifications > [App Name] and toggle "Allow Notifications" off. On Android, go to Settings > Apps > [App Name] > Notifications and toggle "Show Notifications" off. Focus modes on iPhone also let you allow notifications from some apps but not others.
Why does my phone say I have a notification but I cannot find it?
The notification badge (the red number on an app icon) stays even after you read the notification. Swipe down to open your notification center and look for the notification there. If it is not in the center, the badge may be from an older notification you already saw. You can usually clear the badge by opening the app.
Do I need to restart my phone to fix missing notifications?
Usually not. Restarting can help if notifications are stuck or an app is malfunctioning, but most missing notifications are caused by a setting you can fix in seconds. Try the steps above first. If notifications still do not show up after checking permissions, channels, and Focus modes, then restart your phone and try again.
