If Android notifications aren’t showing, or they’re turning up several minutes late, the cause is usually a disabled permission, a battery restriction, a blocked notification category, or a background data setting. Start with Settings > Notifications > App notifications. Pick the affected app and check that notifications are turned on.
Quick fix
Work through these steps in order:
- Open Settings > Notifications > App notifications.
- Choose the affected app, then enable Allow notifications.
- Go to Settings > Apps > [App name] > Battery and select Unrestricted or Not optimized.
- Open the app’s Mobile data settings and allow background data.
- Temporarily switch off Do Not Disturb, Battery Saver, and Data Saver.
- Restart the phone. Then test the app again.
Keep in mind: Menu names differ across Google Pixel, Samsung Galaxy, OnePlus, Xiaomi, Motorola, and other Android phones. If an option isn’t where you expect it, use the search bar in Settings.
Why Android notifications stop working
Android handles notifications at several levels. An app might have permission to show alerts while one particular notification category, such as direct messages, calls, order updates, or reminders, is still blocked.
Battery and data controls can cause trouble too. If Android suspends an app’s background activity, that app may not check for new information right away.
| Symptom | Likely cause | Setting to check |
|---|---|---|
| No notifications from one app | Permission or category disabled | App notification settings |
| Notifications arrive after opening the app | Background activity restricted | Battery and background data |
| No notifications from several apps | Do Not Disturb or Battery Saver | Quick Settings and Modes |
| Notifications appear without sound | Silent category or low volume | Notification sound and volume |
| Only lock-screen alerts are missing | Lock-screen privacy setting | Lock-screen notifications |
1. Turn on notification permission for the app
On Android 13 and newer, newly installed apps have to ask for permission before they can send notifications. If you declined that prompt, the app can’t display alerts.
- Open Settings.
- Tap Notifications, then App notifications.
- Select the affected app.
- Turn on Allow notifications.
- Check any notification categories listed there. Make sure the category you need is enabled.
There’s a quicker route as well. Press and hold the app icon, tap App info, and choose Notifications.
2. Remove the app’s battery restrictions
If notifications show up only after you unlock the phone or open the app, Android is probably limiting what it can do in the background.
- Open Settings > Apps.
- Choose the app, then tap Battery or App battery usage.
- Select Unrestricted.
Samsung phones have another setting to check. Go to Settings > Battery > Background usage limits, then remove the app from Sleeping apps and Deep sleeping apps if you need alerts to arrive promptly.
Unrestricted battery access may use a little more power. It’s best reserved for messaging, security, calendar, delivery, and other apps where immediate notifications matter.
3. Let the app use background data
Blocking background data can delay push notifications, particularly when the phone is using mobile data.
- Open the affected app’s App info page.
- Tap Mobile data & Wi-Fi, Data usage, or the closest equivalent on your phone.
- Enable Background data.
- If Data Saver is on, allow Unrestricted data usage for the app.
4. Check Do Not Disturb and notification volume
Do Not Disturb doesn’t always block the notification itself. It can suppress the sound, vibration, pop-up, or all of them while alerts quietly pile up in the notification panel.
- Swipe down twice to open Quick Settings.
- Switch off Do Not Disturb, Bedtime mode, or any active Focus or Mode profile.
- Press either volume button and expand the volume controls.
- Turn up the Ring & notification volume.
If just one kind of alert stays silent, go back to the app’s notification categories. Change the affected category from Silent to Default or Alerting.
5. Look inside the app’s notification settings
Messaging, email, social media, and shopping apps often have their own notification controls. So Android permission can be enabled while alerts are switched off for one account, conversation, inbox, or event type.
Open the app and check Settings > Notifications. Confirm that you’re signed in to the right account and that the alert types you want are enabled. For a messaging app, see whether the affected conversation has been muted.
6. Clear the cache and install updates
- Go to Settings > Apps > [App name] > Storage & cache.
- Tap Clear cache.
- Open Google Play Store and install any available updates for the app.
- Check Settings > System > Software update for Android updates.
- Restart the phone.
Don’t tap Clear storage unless you have your login details and know the app’s data is synchronized. Clearing storage signs you out and deletes settings stored locally by the app.
7. Reset app preferences
If the problem affects several apps and nothing above has worked, try resetting app preferences:
- Open Settings > Apps.
- Tap the three-dot menu.
- Choose Reset app preferences.
- Confirm the reset, then restart the phone.
This normally won’t erase personal files. It may, however, re-enable disabled apps, reset default apps, and restore the defaults for permissions or background restrictions. Check your preferences again afterward.
Mistakes that can keep notifications from working
- Checking only the main notification switch: A separate category may still be disabled.
- Using task-killer apps: Repeatedly force-closing background services can hold up push notifications.
- Restricting Google Play services: A lot of apps depend on it for push messages.
- Leaving an app in deep sleep: Battery tools added by some phone makers can prevent background delivery.
- Reinstalling before checking the account: Notifications may be disabled on the server, or just for one conversation.
Test whether the fix worked
Lock the phone and ask someone to send a test message, or trigger a legitimate alert from the service that’s been affected. Give it a minute without opening the app. You should see the notification on the lock screen and in the notification panel, along with the expected sound or vibration.
Still getting notifications only after opening the app? Test once on Wi-Fi and once on mobile data. If the problem happens on only one network, the likely cause may be a VPN, Private DNS service, firewall, router filter, or restricted network connection rather than Android’s notification settings.
