Android Notifications Not Showing? How to Fix App Alerts

Last updated: June 2026 ✅

Android notifications are essential for messages, emails, reminders, banking alerts, delivery updates, calendar events, social media replies, and app warnings. When they stop showing, arrive late, make no sound, or appear only after you open the app, it can feel like your phone is not working properly.

This problem is more common than many people think. Sometimes notifications are disabled for one app. Sometimes Do Not Disturb is blocking alerts. In other cases, Battery Saver, Adaptive Battery, background data restrictions, app permissions, notification categories, or a recent app update may be causing the issue.

The good news is that most Android notification problems can be fixed without resetting your phone. You just need to check the right settings in the right order.

In this guide, you will learn how to fix Android notifications not showing step by step. Start with the quick fixes first, then move to the deeper troubleshooting steps if app alerts still do not appear.

Quick Answer: How to Fix Android Notifications Not Showing

If Android notifications are not showing, try these quick fixes first:

Restart your Android phone.
Make sure notifications are enabled for the app.
Turn off Do Not Disturb.
Check notification categories for that specific app.
Make sure the app is not muted or set to silent.
Turn off Battery Saver temporarily.
Allow background data for the app.
Update the app from the Google Play Store.
Clear the app cache.
Check whether the app has its own notification settings.

If only one app is not sending notifications, focus on that app’s notification settings, battery settings, background data, and in-app alert preferences. If many apps are not showing notifications, check system-wide settings such as Do Not Disturb, Battery Saver, notification permissions, focus modes, and Android updates.

Why Are Android Notifications Not Showing?

Android notifications may stop showing for several reasons. In many cases, the app is not allowed to send alerts. This can happen if notifications were accidentally disabled, if the app was set to silent, or if a specific notification category was turned off.

Android also has several features designed to reduce distractions and save battery. Do Not Disturb can block alerts. Focus Mode can pause selected apps. Battery Saver can limit background activity. Adaptive Battery can reduce background activity for apps you do not use often. Data Saver can prevent apps from syncing in the background.

Some apps also have their own notification settings inside the app. For example, a messaging app may have notification settings for chats, groups, calls, mentions, reactions, and reminders. Even if Android notifications are enabled, the app itself may still be blocking certain alerts.

The best way to solve the problem is to check both system settings and app settings.

1. Restart Your Android Phone

Before changing advanced settings, restart your phone. A simple restart can fix temporary notification glitches, stuck background services, connection problems, and app sync delays.

To restart most Android phones:

Press and hold the power button.
Tap Restart.
Wait for the phone to turn back on.
Ask someone to send you a test message or wait for the app to send a new alert.

On some Android phones, you may need to press the power button and volume up button together to open the power menu.

Restarting does not delete your files. It is one of the safest first steps when notifications stop working suddenly.

2. Make Sure App Notifications Are Enabled

If notifications are not showing for one specific app, check whether notifications are enabled for that app.

To check app notifications:

Open Settings.
Tap Apps.
Select the app that is not sending notifications.
Tap Notifications.
Turn on notifications.
Review the available notification types.

Some apps have multiple notification categories. For example, a messaging app may have categories for direct messages, group messages, calls, media uploads, mentions, and reminders. Make sure the important categories are enabled.

If the main notification switch is turned off, the app will not be able to send alerts at all.

3. Turn Off Do Not Disturb

Do Not Disturb is one of the most common reasons notifications appear to stop working. When it is enabled, your phone may silence notifications, block banners, hide alerts, or allow only selected people and apps.

To turn off Do Not Disturb:

Swipe down from the top of the screen.
Look for Do Not Disturb in Quick Settings.
Tap it to turn it off if it is enabled.

You can also check it from Settings:

Open Settings.
Tap Sound & vibration or Notifications.
Tap Do Not Disturb.
Turn it off.
Check schedules and exceptions.

Do Not Disturb may also be scheduled automatically. For example, it may turn on during sleep hours, meetings, driving, gaming, or work time. If notifications disappear only during certain hours, check your Do Not Disturb schedules.

4. Check Focus Mode or App Pause Settings

Some Android phones include Focus Mode or similar features that pause selected apps. When an app is paused, you may not receive notifications from it until the mode is turned off.

To check Focus Mode:

Open Settings.
Tap Digital Wellbeing & parental controls.
Tap Focus Mode.
Check whether the app is selected.
Turn off Focus Mode or remove the app from the paused list.

Some launchers also allow you to pause apps directly from the home screen. If an app icon looks grayed out or paused, long-press it and check whether it has been paused.

This is especially common when notifications stop only for social media, messaging, or entertainment apps.

5. Check Notification Categories or Channels

Android lets apps separate notifications into categories. This is useful because you can allow important alerts while muting less important ones. But it can also cause confusion if the wrong category is turned off.

For example, you may allow notifications from a delivery app but disable order updates. Or you may allow notifications from a messaging app but disable group messages.

To check notification categories:

Open Settings.
Tap Apps.
Select the app.
Tap Notifications.
Review each notification category.
Turn on the categories you want.
Check whether each category is set to alert, silent, or minimized.

If notifications appear silently, tap the category and check sound and vibration settings.

This step is very important when some notifications from an app appear but others do not.

6. Make Sure Notifications Are Not Set to Silent

Sometimes notifications are not missing. They are simply silent. They may appear in the notification shade but make no sound, vibration, or banner.

To check this:

Open Settings.
Tap Apps.
Select the app.
Tap Notifications.
Tap the notification category.
Make sure it is set to alert, not silent.
Choose a notification sound if needed.
Enable vibration if desired.

Also check your phone’s volume:

Press a volume button.
Tap the three dots or settings icon on the volume panel.
Make sure notification volume is not muted.

Some phones separate ringtone, media, alarm, and notification volume. Make sure the notification volume is not turned all the way down.

7. Check Lock Screen Notification Settings

If notifications arrive but do not appear on the lock screen, your lock screen notification settings may be hiding them.

To check lock screen notifications:

Open Settings.
Tap Notifications.
Tap Lock screen notifications.
Choose whether to show notifications.
Decide whether to hide sensitive content.

If you choose to hide sensitive content, you may see that a notification arrived, but not the message preview. This is normal and can be useful for privacy.

If lock screen notifications are turned off completely, alerts may only appear after you unlock the phone.

8. Turn Off Battery Saver Temporarily

Battery Saver helps extend battery life, but it can also limit background activity. When background activity is limited, some apps may not send notifications immediately.

To test this:

Open Settings.
Tap Battery.
Tap Battery Saver.
Turn Battery Saver off.
Wait for a new notification or send yourself a test message.

If notifications start working after Battery Saver is turned off, battery restrictions may have been delaying alerts.

You do not need to keep Battery Saver off forever. But for important apps like messaging, banking, calendar, delivery, work chat, or security apps, you may need to allow better background activity.

9. Check App Battery Usage Settings

Android may restrict background activity for apps to save battery. This can delay notifications, especially from apps you do not open often.

To check app battery settings:

Open Settings.
Tap Apps.
Select the app.
Tap Battery or App battery usage.
Choose Optimized or Unrestricted if available.
Avoid Restricted for important notification apps.

The exact options vary by phone brand and Android version. Some phones show options like Unrestricted, Optimized, and Restricted. Others may show Allow background activity or Put app to sleep.

For important apps, avoid aggressive restrictions. If a messaging app is restricted, it may only show new messages after you open it.

10. Allow Background Data

Some apps need background data to receive notifications. If background data is blocked, the app may not sync until you open it.

To allow background data:

Open Settings.
Tap Apps.
Select the app.
Tap Mobile data & Wi-Fi or Data usage.
Turn on Background data.
If available, allow unrestricted data usage when Data Saver is on.

This is especially important for messaging apps, email apps, cloud apps, banking apps, delivery apps, and work apps.

If notifications work on Wi-Fi but not on mobile data, background data or data saver settings may be the cause.

11. Turn Off Data Saver Temporarily

Data Saver reduces background data usage. This can help save mobile data, but it may also delay notifications from apps that need to sync in the background.

To turn off Data Saver:

Open Settings.
Tap Network & internet.
Tap Data Saver.
Turn it off temporarily.
Test your notifications again.

If notifications start working, you can either keep Data Saver off or allow unrestricted data for specific important apps.

For example, you may want unrestricted data for WhatsApp, Gmail, banking apps, calendar apps, or work communication apps.

12. Update the App

If notifications stopped after a bug, the app developer may have released an update to fix it.

To update the app:

Open Google Play Store.
Tap your profile picture.
Tap Manage apps & device.
Tap Updates available.
Find the app.
Tap Update.

After updating, open the app once. Some apps need to be opened after an update before background notifications work properly again.

If notifications stopped immediately after the latest update, the new version may have a bug. In that case, check recent app reviews or wait for the developer to release another fix.

13. Update Android System Software

Sometimes notification problems are related to system bugs or compatibility issues. Keeping Android updated can help with notification behavior, app compatibility, security, and system stability.

To check for Android updates:

Open Settings.
Tap System.
Tap Software update or System update.
Install any available update.
Restart your phone.

The exact menu depends on your device manufacturer. Samsung, Google Pixel, Motorola, Xiaomi, OnePlus, and other brands may use slightly different names for system updates.

After updating, test notifications again.

14. Clear the App Cache

A corrupted app cache can cause notification issues, sync problems, login problems, and delayed alerts.

To clear app cache:

Open Settings.
Tap Apps.
Select the app.
Tap Storage & cache.
Tap Clear cache.
Open the app again.

Clearing cache usually does not delete your account, messages, photos, or personal files. It removes temporary files that the app can rebuild.

This is a safe fix to try when notifications stop working for one app.

15. Check the App’s Own Notification Settings

Some apps have internal notification settings separate from Android settings. This is very common with messaging, email, social media, calendar, banking, shopping, and delivery apps.

Open the app and look for settings such as:

Notifications
Alerts
Push notifications
Message notifications
Email notifications
Sound and vibration
Mentions
Group notifications
Order updates
Marketing notifications
Reminder settings

For example, a chat app may allow direct messages but mute group chats. An email app may notify only for priority inbox messages. A shopping app may disable delivery updates while still allowing promotional alerts.

Check the app’s internal settings carefully.

16. Make Sure You Are Logged In

Some apps cannot send account-based notifications if you are signed out or if account sync is broken.

Open the app and check:

Are you still logged in?
Does the app show account errors?
Does it ask you to verify your identity?
Are notifications enabled inside the account settings?
Does the app need permission again after an update?

For email, banking, cloud, and work apps, authentication problems can stop notifications until you sign in again.

If needed, sign out and sign back in. Do this carefully with banking apps, authentication apps, or work apps, because you may need additional verification.

17. Reinstall the App

If one app still refuses to send notifications after checking settings, cache, battery, data, and updates, reinstalling it may help.

To reinstall an app:

Press and hold the app icon.
Tap Uninstall.
Restart your phone.
Open Google Play Store.
Install the app again.
Sign in.
Allow notifications when asked.

Before uninstalling, make sure important data is backed up. This is especially important for messaging apps, note apps, authenticator apps, and work apps.

After reinstalling, Android may ask whether you want to allow notifications. Make sure you choose Allow.

18. Check Notification History

Notification History can help you find out whether notifications are being received but dismissed, minimized, or hidden.

To check Notification History:

Open Settings.
Tap Notifications.
Tap Notification history.
Turn it on if it is off.
Review recent notifications.

If notifications appear in history but not on your screen, the problem may be related to lock screen settings, silent notifications, notification categories, or Do Not Disturb.

If the app does not appear in notification history at all, the app may not be sending notifications, or Android may be blocking them before they arrive.

19. Check Wearables, Smartwatches, or Companion Devices

If you use a smartwatch or wearable device, notifications may be redirected, filtered, or muted depending on your watch settings.

Check:

Watch notification settings
Companion app settings
Do Not Disturb sync between phone and watch
App notification filters
Bluetooth connection status

Sometimes the phone receives notifications, but the watch settings change how they appear or whether the phone vibrates.

If you suspect this is the issue, temporarily disconnect the watch and test notifications directly on the phone.

What Not to Do When Android Notifications Stop Showing

When notifications stop working, avoid risky or unnecessary fixes.

Do not factory reset your phone too early

A factory reset should be the last option. Most notification problems can be solved by checking app notifications, Do Not Disturb, battery settings, background data, and app updates.

Do not install random notification booster apps

Apps that promise to “fix notifications” or “boost background apps” may show ads, request unnecessary permissions, or interfere with system behavior.

Do not disable battery features for every app

Setting every app to unrestricted battery usage can reduce battery life. Use unrestricted battery only for important apps that need instant alerts.

Do not allow every permission blindly

Notification problems are usually not solved by allowing unrelated permissions. A messaging app may need notifications and background data, but it does not need every permission on your phone.

Do not ignore app-specific settings

Many notification problems happen inside the app itself. Always check both Android settings and the app’s own notification menu.

When Should You Contact App Support?

Contact the app developer if:

Notifications fail only for one app.
The app is updated and settings look correct.
Notifications stopped after a recent app update.
The app shows account or sync errors.
Other users are reporting the same problem.
The app is related to banking, work, security, or authentication.

When contacting support, include:

Phone model
Android version
App version
When the issue started
Whether notifications are enabled in Android settings
Whether Battery Saver or Data Saver is on
Whether the issue happens on Wi-Fi, mobile data, or both

This helps support understand whether the problem is app-related, account-related, or device-related.

Best Fix Order: What You Should Try First

If you want the safest order, follow this:

Restart your phone.
Check whether notifications are enabled for the app.
Turn off Do Not Disturb.
Check Focus Mode or paused apps.
Review notification categories.
Make sure notifications are not silent.
Check lock screen notification settings.
Turn off Battery Saver temporarily.

This order starts with simple settings and only moves to stronger fixes later.

FAQ: Android Notifications Not Showing

Why are my Android notifications not showing?

Android notifications may not show because notifications are disabled for the app, Do Not Disturb is on, the app is paused, notification categories are turned off, Battery Saver is limiting background activity, or the app is restricted from using background data.

Why do notifications only appear when I open the app?

This usually happens when the app cannot run or sync properly in the background. Check background data, Battery Saver, app battery usage, Data Saver, and the app’s internal notification settings.

Why are my notifications silent?

Notifications may be set to silent in Android notification settings. Open Settings, choose the app, tap Notifications, and check the notification category. Make sure it is set to alert instead of silent, and check notification volume.

Why am I not getting notifications on my lock screen?

Lock screen notifications may be disabled or set to hide content. Open Settings, go to Notifications, and check lock screen notification settings. You can choose to show all notifications or hide sensitive content.

Can Battery Saver delay notifications?

Yes. Battery Saver can limit background activity, which may delay notifications from some apps. Turn it off temporarily to test whether it is causing the problem.

Should I set every app to unrestricted battery usage?

No. Use unrestricted battery only for important apps that need instant alerts, such as messaging, banking, calendar, delivery, or work apps. Setting every app to unrestricted can reduce battery life.

Will clearing cache delete my messages?

Usually, no. Clearing app cache removes temporary files. It normally does not delete your messages, account, photos, or personal files. However, clearing app data is different and should be done more carefully.

Should I factory reset my phone?

A factory reset should be the last option. Most Android notification problems can be fixed by checking notification settings, Do Not Disturb, battery settings, background data, app updates, and app-specific notification settings.

Final Thoughts

When Android notifications are not showing, do not panic and do not reset your phone immediately. Most notification problems are caused by settings that can be changed in a few minutes.

Start with the basics: restart your phone, enable notifications for the app, turn off Do Not Disturb, and check notification categories. Then move to battery settings, background data, Data Saver, app updates, cache, and in-app notification settings.

If only one app is affected, focus on that app. If many apps are affected, check system-wide settings like Do Not Disturb, Focus Mode, Battery Saver, notification permissions, and Android updates.

The most important rule is simple: notifications depend on both Android settings and app settings. Check both, test carefully, and only use advanced fixes if the simple steps do not solve the problem.
