Android notifications: how to get text, email, voicemail, and app alerts

Part of our guide on apps keep crashing after android update samsung

What you need to get Android notifications

You need an Android phone running Android 8.0 or later to fully use notification controls like channels and priorities.

Have your phone set up with the carrier and an active SIM for texts and voicemail alerts.

Ensure your apps like Messages, Gmail, Outlook, and Phone are installed and updated for best compatibility.

Basic tools you need are access to the Settings app, and optionally Google Play Store for app updates. For the detail, see our notes on steps to locate lost phone.

Some Android phones may have manufacturer-specific modifications that affect how notifications work. For example, on Samsung devices, the One UI software adds extra notification controls accessible through Settings > Notifications > Advanced settings. Here, you can customize how notifications appear during calls or hide sensitive content on the lock screen. These additional options can sometimes override the general Android settings, so checking them can help ensure you receive notifications as expected.

If you use multiple user profiles or guest modes on your Android phone, notifications might not appear for apps installed under a different profile. Notifications are profile-specific, so make sure you are enabling notifications in the profile you use most. For phones that support work profiles, notifications from work apps can be muted or hidden based on your organization’s policy, which is another factor to consider when troubleshooting missing alerts.

• Android 8.0+ phone
• Active carrier SIM card
• Updated Messages, Gmail, Outlook, Phone apps
• Access to Settings app

How to enable notifications for text messages

Text message notifications depend on your default SMS app, usually Messages. Without setting it as default, alerts won’t work. Before you commit to anything, it is worth looking at how to transfer data from android.

Open Settings, tap Apps & notifications > See all apps, find Messages, then tap Notifications.

Enable all notification types here. Enable 'On lock screen' to see alerts without unlocking your phone.

Confirm Messages is your default SMS app in Settings > Apps & notifications > Default apps > SMS app. It helps to understand android apps unavailable family share before going further.

If you don’t get alerts, verify that Battery Optimization is off for Messages in Settings > Battery > Battery Optimization.

In some cases, text message notifications may be delayed or not appear due to network issues or carrier restrictions. For instance, if you are in an area with poor cellular coverage or if your carrier's SMS center is experiencing outages, notifications might not arrive promptly. You can test notification functionality by sending a text message from another phone and observing whether the alert sounds or appears on your device.

If you use a third-party messaging app instead of the default Messages app, notification settings will need to be managed within that app as well as in system settings. Some popular SMS apps, like Textra or Pulse, have their own notification customization that can override system settings. Ensure you configure notifications inside the app and grant it the necessary permissions, including access to SMS and contacts.

2. Tap Notifications and toggle on all categories.
3. Go to Settings > Apps & notifications > Default apps > SMS app and set Messages as default.
4. Disable Battery Optimization for Messages app to avoid blocking alerts.

How to enable Gmail and Outlook email notifications

Email apps like Gmail and Outlook require two layers of notification permission: one inside the app, another in Android system settings.

Open the Gmail app, tap the menu, then Settings. Select your account and ensure Notifications are set to All or High priority.

Next, go to Android Settings > Apps & notifications > Gmail > Notifications and turn on all categories. There is more on offloading apps to save space in a separate guide.

Repeat similar steps for Outlook: inside the app go to Settings > Notifications, then also enable in Android Settings.

Battery Optimization can block email notifications if enabled, so disable it for Gmail and Outlook if emails don’t alert.

1. In Gmail app, open menu > Settings > select account > Notifications > choose All.
2. Go to Settings > Apps & notifications > Gmail > Notifications and enable all.
3. In Outlook app, open Settings > Notifications and make sure alerts are on.
4. In Android Settings, enable notifications for Outlook app as well.
5. Disable Battery Optimization for Gmail and Outlook to prevent blocked alerts.

How to enable voicemail notifications on Android

Voicemail alerts depend on your carrier, voicemail service, and the Phone app’s notification settings.

Open Phone app, tap the three dots or menu, then Settings > Voicemail and confirm notifications are enabled.

In Android Settings > Apps & notifications > Phone > Notifications, ensure voicemail alerts are on.

If no notifications appear, check carrier voicemail settings and confirm your voicemail number is set correctly in Phone app.

Some carriers use visual voicemail apps; enable notifications in those apps as well.

Voicemail notification issues can also arise from outdated voicemail apps or services. Some carriers offer visual voicemail apps separate from the default Phone app, and these require independent notification permissions. If you recently switched carriers or updated your phone, verify you have the correct voicemail app installed and updated to the latest version.

As an additional check, if voicemail notifications do not appear but you know you have messages, try calling your voicemail number manually. If you can hear new messages but receive no notifications, it indicates a settings or app permission issue rather than a carrier problem. In this case, resetting app preferences in Settings > Apps > Reset app preferences can sometimes restore voicemail alerts.

1. Open Phone app > Menu > Settings > Voicemail > enable notifications.
2. Go to Settings > Apps & notifications > Phone > Notifications and turn on voicemail alerts.
3. Verify correct voicemail number in Phone app settings.
4. Check carrier voicemail service status or app for visual voicemail notification settings.

How to enable app notifications on Android

Each app controls its own notification categories or channels that you must enable individually.

Go to Settings > Apps & notifications > See all apps > select the app you want notifications from > Notifications.

Toggle on the notification categories listed. Some apps show dozens of categories for different alert types.

Ensure the app has permission to send notifications and is not restricted by battery optimization.

If the app uses background data, make sure Background Data is allowed in the app’s Data usage settings.

1. Open Settings > Apps & notifications > See all apps.
2. Select an app, tap Notifications.
3. Enable all notification categories you want alerts from.
4. Disable Battery Optimization for apps you need instant alerts from.
5. Allow Background Data and permissions for notifications.

How to check notification settings and troubleshoot common issues

If notifications don’t appear, start by checking Do Not Disturb is off or properly configured to allow exceptions.

Review Battery Optimization settings as aggressive power saving kills many app alerts.

Use Settings > Apps & notifications > Notifications > Notification history to see if notifications arrived but were hidden.

Restart your phone after changing notification or app permissions, as some settings require a reboot to apply.

Clear app cache or reinstall the app if notifications still fail after all settings look correct.

Some Android phones have aggressive memory management that forcibly stops apps running in the background, which can prevent notifications. To prevent this, you may need to lock apps in memory or whitelist them in the phone’s battery or device care settings. For example, on Xiaomi phones, enabling 'Autostart' for key apps and locking them in recent apps can improve notification reliability.

If notifications suddenly stop appearing after a system update, this can indicate a bug or compatibility issue. Checking for app updates, clearing cache, or even booting into Safe Mode to test notifications without third-party apps can help isolate the problem. Reporting persistent issues to the app developer or your device manufacturer can lead to fixes in future updates.
