Phone notifications help you stay updated on messages, missed calls, emails, social media activity, reminders, and other important alerts. When notifications stop working, you may miss important messages or discover that apps only show new updates after you open them.
The problem can happen on both Android phones and iPhones. Sometimes, the cause is a simple setting such as Do Not Disturb, disabled app notifications, or an overly restrictive battery mode. In other cases, outdated software, background activity restrictions, or network problems may prevent alerts from arriving on time.
The good news is that you can often restore notifications by checking a few settings and troubleshooting the affected app.
In this guide, you will learn how to fix phone notifications not working with easy steps for Android and iPhone.
Why Are My Phone Notifications Not Working?
Before trying a fix, identify when the problem occurs. Do notifications fail for every app, or only for one application? Do they arrive late, or do they never appear?
Common causes include:
- Notifications are disabled: The phone or app may be blocking alerts.
- Do Not Disturb is enabled: Focus modes may silence notifications.
- Battery-saving restrictions: Background activity may be limited.
- Poor internet connectivity: Messaging and email apps may not receive updates promptly.
- Background app restrictions: The operating system may prevent apps from refreshing.
- Outdated software: Bugs can interfere with notification delivery.
- Incorrect notification permissions: Alerts, lock-screen notifications, or notification sounds may be disabled.
- App glitches: A particular application may need to be restarted or updated.
- Incorrect date and time: Incorrect system settings can sometimes interfere with online services.
- Notification summaries or schedules: Alerts may be delivered quietly or grouped instead of appearing immediately.
Try the following solutions in order, starting with the simplest checks.
1. Restart Your Phone
Restarting your phone is one of the easiest ways to fix temporary software problems.
If a background service becomes stuck, notifications may stop appearing until the service starts working again.
How to restart your phone:
- Save any open work.
- Open the power menu.
- Select Restart if available, or power the phone off and turn it back on.
- Wait for the phone to reconnect to your network.
- Ask someone to send you a test message or check an app that normally sends notifications.
If alerts return after restarting, a temporary software issue may have been responsible.
If notifications still do not work, continue with the next solution.
2. Turn Off Do Not Disturb or Focus Mode
Do Not Disturb and similar modes can silence calls, messages, and app notifications.
You may have enabled one accidentally, or it may turn on automatically according to a schedule.
On Android:
- Swipe down from the top of the screen to open Quick Settings.
- Look for Do Not Disturb, Modes, or a similar option.
- Turn it off if it is enabled.
- Open Settings and search for Do Not Disturb or Modes.
- Check whether an automatic schedule is activating it.
On iPhone:
- Open Control Center.
- Find the Focus control.
- Check whether Do Not Disturb, Sleep, Work, or another Focus mode is active.
- Turn it off if you want notifications to appear normally.
- Open Settings and select Focus to review schedules and allowed apps.
Some Focus modes permit notifications from selected people or applications while silencing others. Review these settings if only certain alerts are missing.
3. Enable Notifications for the Affected App
If notifications are missing from just one application, its notification permission may be disabled.
For example, you might receive text messages normally but get no alerts from WhatsApp, Gmail, Facebook, or another app.
On Android:
- Open Settings.
- Select Notifications or Apps, depending on your phone.
- Open App notifications.
- Select the affected application.
- Enable notifications.
- Review any available notification categories or channels.
Some Android phones let you control different notification types separately, such as messages, calls, reminders, and promotional alerts.
On iPhone:
- Open Settings.
- Select Notifications.
- Choose the affected application.
- Turn on Allow Notifications.
- Enable the desired alert locations, such as Lock Screen, Notification Center, or Banners.
- Enable Sounds if you want an audible alert.
Menu names can vary slightly depending on your operating system version.
After changing the settings, test the application again.
4. Check Notification Sounds and Silent Mode
Sometimes notifications arrive, but you cannot hear them. This may make it seem as though notifications are not working.
Possible causes include silent mode, low notification volume, muted app sounds, or a connected Bluetooth device.
Try these steps:
- Check whether the phone is in silent mode.
- Increase the appropriate ring or notification volume.
- Open the affected app’s notification settings.
- Make sure notification sounds are enabled.
- Disconnect Bluetooth headphones or speakers temporarily if alerts may be playing through them.
- Test the phone with a new message or alert.
On iPhones, check the Ring/Silent control if your model has one, or review the Action button configuration where applicable. Also check Settings under Sounds & Haptics.
On Android, look for Sound and vibration settings and the notification volume control.
Remember that silent mode and Do Not Disturb are different. Silent mode may mute sound while allowing visual notifications, whereas Do Not Disturb can suppress alerts according to its rules.
5. Disable Battery Saver Temporarily
Battery-saving features can limit background activity to extend battery life. Depending on the phone and app, this can delay notifications.
This is particularly noticeable with messaging, email, and other applications that need to maintain background connectivity.
On Android:
- Open Settings.
- Select Battery or Battery and device care.
- Find Battery Saver, Power Saving, or a similar option.
- Turn it off temporarily.
- Check whether notifications start arriving normally.
If one app remains affected, open its battery settings and look for options such as Unrestricted, Optimized, or Restricted. Use unrestricted background activity only when necessary, because it can increase battery consumption.
On iPhone:
- Open Settings.
- Select Battery.
- Check whether Low Power Mode is enabled.
- Turn it off temporarily and test notification delivery.
Low Power Mode can affect background activity, particularly for some apps and services. However, it is not necessarily the cause of every notification problem.
6. Check Your Internet Connection
Many applications need an internet connection to deliver notifications. If Wi-Fi or mobile data is unreliable, alerts may arrive late or appear only after opening the app.
How to troubleshoot connectivity:
- Open a website to confirm that the internet is working.
- If you are using Wi-Fi, try switching to mobile data.
- If you are using mobile data, connect to a reliable Wi-Fi network.
- Turn Airplane Mode on briefly, then turn it off.
- Reopen the affected app and check whether new content loads.
If notifications work on one network but not another, the problem may involve the connection, network restrictions, or a VPN.
Also check whether the affected app is allowed to use mobile data. On some phones, Data Saver or background-data restrictions can interfere with notifications.
If several apps stop receiving alerts at the same time, check the internet connection before changing individual app settings.
7. Allow Background App Activity
Some apps need permission to refresh content or run background tasks. If background activity is restricted, notifications may be delayed until the app is opened.
On Android:
- Open Settings.
- Select Apps.
- Choose the affected app.
- Open its battery or app-usage settings.
- Review whether background activity is restricted.
- Allow appropriate background usage if the phone offers that option.
The exact settings depend on the Android version and manufacturer.
On iPhone:
- Open Settings.
- Select General.
- Choose Background App Refresh.
- Check whether it is enabled.
- Confirm that the affected app is allowed to refresh in the background, where applicable.
Background App Refresh is not the sole mechanism for delivering iPhone push notifications, so disabling it does not automatically explain every missing alert.
After adjusting the relevant settings, leave the app configured normally and test whether notifications arrive.
8. Update the App
An outdated application may contain bugs that interfere with notifications. Updating it can resolve known problems and improve compatibility with your operating system.
On Android:
- Open the Google Play Store.
- Search for the affected app.
- Open its store page.
- Tap Update if an update is available.
- Restart the app and test notifications.
On iPhone:
- Open the App Store.
- Search for the application.
- Open its page.
- Tap Update if available.
- Open the app and check its notification settings.
If the problem began immediately after an update, check whether another update is available and consult the app’s official support information.
Avoid downloading application installers from unfamiliar websites.
9. Update Your Phone’s Operating System
System updates can fix software bugs, improve notification handling, and resolve compatibility issues.
If notifications stopped working after a system change, an available maintenance update may help.
On Android:
- Open Settings.
- Search for Software update or System update.
- Check for available updates.
- Install any suitable update according to the manufacturer’s instructions.
On iPhone:
- Open Settings.
- Select General.
- Tap Software Update.
- Check whether a newer version is available.
- Follow the instructions to install it.
Before a major update, make sure the phone has sufficient battery power and available storage. Backing up important data is also recommended.
After updating, test notifications from the apps that were affected.
10. Check Notification Settings Inside the App
Some applications have their own notification controls in addition to the phone’s system settings.
For example, a messaging app may let you mute individual conversations, while an email app may allow alerts only for selected inboxes.
What to check:
- Open the affected app.
- Find its Settings or Preferences menu.
- Select Notifications.
- Check whether messages, calls, emails, or other alerts are enabled.
- Review muted conversations, selected accounts, notification schedules, and other app-specific options.
- Save any changes and test the app.
If only one conversation or email account is affected, the problem may be inside the app rather than the phone’s general notification settings.
11. Check Lock-Screen and Notification Display Settings
Notifications may be arriving without appearing on the lock screen or as pop-up banners.
This can happen when the phone is configured to hide notification content, display alerts only in the notification center, or group notifications quietly.
On Android:
- Open Settings.
- Select Notifications.
- Look for Lock screen notifications.
- Choose an appropriate display option.
- Check whether the affected app is allowed to display notifications on the lock screen.
On iPhone:
- Open Settings.
- Select Notifications.
- Choose the affected app.
- Check Lock Screen, Notification Center, and Banners.
- Review whether notifications are being delivered immediately or included in a scheduled summary.
If alerts are appearing in Notification Center but not as banners, adjust the display settings rather than reinstalling the app.
12. Turn Off Scheduled Notification Summaries if Needed
Some phones group notifications and deliver them at selected times rather than displaying every alert immediately.
This can make it seem as though notifications are not working, even when they are being collected correctly.
On iPhone:
- Open Settings.
- Select Notifications.
- Tap Scheduled Summary.
- Check whether the affected app is included.
- Disable the summary or adjust its schedule if you want those notifications delivered separately.
On Android, check whether the phone has notification history, notification grouping, or app-specific scheduling features that could explain the behavior.
The exact options depend on your device and software version.
13. Set Date and Time to Automatic
Incorrect date or time settings can sometimes interfere with synchronization and online services.
Using automatic date and time helps your phone stay synchronized with the network.
On Android:
- Open Settings.
- Select System or General management.
- Open Date and time.
- Enable automatic date and time, if available.
- Enable the automatic time zone option when appropriate.
On iPhone:
- Open Settings.
- Select General.
- Tap Date & Time.
- Enable Set Automatically.
After changing the setting, reconnect to the internet and test the affected app.
This fix is less common than checking notification permissions or Focus modes, but it can help when several online services are behaving unexpectedly.
14. Clear the App Cache on Android
Temporary app files can sometimes become corrupted and cause unexpected behavior. Clearing an app’s cache may help if notifications fail for a particular Android application.
How to clear the cache:
- Open Settings.
- Select Apps.
- Choose the affected application.
- Open Storage or Storage and cache.
- Tap Clear cache, if available.
- Reopen the app and test notifications.
Important: Choose Clear cache rather than Clear storage or Clear data unless you understand the consequences. Clearing storage may remove local app data, settings, or login information.
iPhone does not provide a universal system setting to clear an individual app’s cache. For some apps, you may need to use the app’s own storage settings or reinstall it after checking that important data is backed up or synchronized.
15. Reinstall the Affected App
If notifications still fail for one application after you have checked its permissions and settings, reinstalling it may resolve corrupted app files.
Before uninstalling, make sure important information is backed up or synchronized. Some messaging apps store data locally, so deleting the app can remove conversations or downloaded files.
Steps to follow:
- Confirm that you know your account login details.
- Back up important app data if necessary.
- Uninstall the affected app.
- Restart your phone.
- Reinstall the app from the official app store.
- Sign in and grant the required notification permissions.
- Check the app’s internal notification settings.
Send a test message or wait for a new alert to determine whether the issue is resolved.
Do not reinstall every app if only one application is affected. Start with the specific app that has the problem.
16. Reset Network Settings as a Last Resort
If several apps fail to receive notifications and you have already ruled out notification permissions, Focus modes, and background restrictions, a network configuration problem may be involved.
Resetting network settings can help in some cases, but it should not be an early troubleshooting step.
Before proceeding, understand that it may remove saved Wi-Fi networks, passwords, VPN configurations, and other network preferences.
On Android:
- Open Settings.
- Search for Reset network settings.
- Review the options carefully.
- Select the network reset option if appropriate.
- Confirm and reconnect to your Wi-Fi network.
The wording varies by manufacturer, and some phones separate Wi-Fi, mobile network, and Bluetooth resets.
On iPhone:
- Open Settings.
- Select General.
- Tap Transfer or Reset iPhone.
- Select Reset.
- Choose Reset Network Settings.
- Follow the on-screen instructions.
Do not select Erase All Content and Settings for this problem.
After the reset, reconnect to the internet and check whether notifications work again.
