How to Fix SMS Notifications That Are Not Working on Galaxy S23 Ultra

SMS notifications are an integral part of modern smartphone usage. Getting a sound alert or on-screen notification when you receive a new text message is crucial for staying connected. If your Samsung Galaxy S23 Ultra isn’t alerting you to new SMS messages, it can be a frustrating experience.

SMS notifications often stop working due to incorrect settings, temporary software glitches, or even issues with your carrier. We’ll cover the most common causes behind this problem and walk you through various solutions in a step-by-step manner.

Basic Checks

Before diving into specific troubleshooting steps, there are a few simple checks that can quickly address the issue:

Verify Signal Strength: Check your Galaxy S23 Ultra’s signal bars. A weak signal might prevent you from receiving text messages and their notifications.
Restart Your Device: A classic solution, restarting your phone can clear temporary glitches causing the notification issue.
Airplane Mode: Make sure Airplane Mode is turned off by checking your device’s quick settings.

If these quick checks don’t solve the problem, move on to the troubleshooting steps below.

Checking Notification Permissions

Incorrect notification permissions are a common reason for missing SMS alerts. Here’s how to check them:

Go to your phone’s Settings app.
Tap on Notifications.
Tap on App notifications.
Locate your messaging app (e.g., Samsung Messages or Google Messages) and tap on it.
Make sure the toggle for Allow notifications is switched on.
Under the various notification categories, ensure settings like sound and vibration are enabled as desired.

Verifying Battery Optimization Settings

Sometimes, aggressive battery saving features can affect notifications. Follow these steps to check:

In your Settings app, go to Battery and device care.
Tap on Battery.
Look for Background usage limits. You may need to tap on “More” to access this.
Check if your messaging app is listed under Sleeping apps or Deep sleeping apps. If so, remove it from that list.

Clearing the App Cache and Data

Clearing an app’s cache and data can resolve issues caused by corrupted temporary files. Here’s how to do it:

Go to Settings and then to Apps.
Find your messaging app and tap on it.
Select Storage.
Tap Clear cache and then Clear data. Note that clearing data will reset some app settings.

Checking Do Not Disturb and Focus Mode

Ensure that Do Not Disturb or Focus Mode aren’t accidentally preventing notifications:

Open your Settings app.
Go to **Sound and vibration ** (or it may be in a Notifications section)
Tap on Do Not Disturb.
Verify that Do Not Disturb is turned off.
If you use Focus Mode, check if any active profiles are blocking text message notifications.

Checking for Network Issues

Issues with your carrier’s network might lead to problems. Here’s how to troubleshoot:

Contact Your Carrier: Reach out to your carrier to inquire about any network problems or outages in your area.
Reset Network Settings: Go to Settings > General management > Reset > Reset network settings. IMPORTANT: This will reset your Wi-Fi, Bluetooth, and cellular settings, so have your Wi-Fi passwords ready.

Addressing Third-Party App Interference

Third-party apps with notification management features might conflict with SMS notifications:

Uninstallation: If you’ve recently installed such an app, try uninstalling it and see if it solves the issue.
Safe Mode: Boot your phone into Safe Mode by holding down the power button and then long-pressing the power-off icon. If notifications work fine in Safe Mode, a third-party app is likely interfering.

Software Updates and Factory Reset

Update Your Phone: Go to Settings > Software update to check for and install any pending system updates.
Factory Reset: As a last resort, perform a factory reset (Settings > General management > Reset > Factory data reset). BACK UP YOUR DATA FIRST as this will wipe your phone.

If you continue to face issues after these steps, please contact Samsung Support for further assistance.
