How do I turn off silent notifications?

To turn off silent notifications on your Samsung phone, go to Settings, tap Notifications, select the app you want to change, and switch the alert style from Silent to Sound and vibration or Sound only. This restores the notification sound so you hear alerts when they arrive.

Silent notifications are often turned on by accident, or Samsung's One UI sets certain apps to silent by default based on how rarely you interact with them. The fix is straightforward once you know where to look, and it takes less than a minute per app.

Below, we cover the most common questions people have about silent notifications on Samsung devices, including why it keeps happening and how to stop it for good.

Why are my Samsung notifications showing as silent?

Your Samsung notifications are showing as silent because the app's alert style has been set to Silent in your notification settings. This means the app can still deliver notifications, but they arrive without any sound or vibration. One UI on Samsung phones separates notifications into two categories: those that make noise and those that do not.

There are a few common reasons this happens:

One UI's adaptive notification feature: Samsung's One UI can automatically move apps to silent if it detects you rarely interact with their notifications. This is meant to reduce noise, but it can catch people off guard.
App install defaults: Some apps are set to silent by default when you first install them, and you have to manually change this.
Accidental changes: It is easy to swipe a notification and tap the wrong option, which can switch an app to silent mode without you realising it.
Software updates: Occasionally, a One UI update can reset notification preferences for certain apps.

The good news is that silent notifications are entirely within your control. You do not need to uninstall anything or reset your phone. A quick visit to your notification settings is all it takes.

What's the difference between silent notifications and Do Not Disturb?

Silent notifications and Do Not Disturb are two separate features on your Samsung phone. Silent notifications are a per-app setting that permanently removes sound from a specific app's alerts. Do Not Disturb is a device-wide mode that mutes all sounds and vibrations temporarily, but does not change individual app settings.

Here is how they differ in practice:

Silent notifications affect one app at a time. If you set your email app to silent, it will always arrive without sound, even when Do Not Disturb is off. The app is permanently quieted until you change it back.
Do Not Disturb affects the whole phone at once. When it is on, no apps make sounds. When you turn it off, every app goes back to its normal notification sound settings.

This distinction matters when you are troubleshooting. If you turn off Do Not Disturb but an app is still silent, the problem is not Do Not Disturb. The app itself has been set to silent in its notification preferences. You will need to go into that specific app's notification settings to restore the sound, which we explain in the next section.

How do you turn off silent notifications for a specific app?

To turn off silent notifications for a specific app on your Samsung phone, open Settings, go to Notifications, find the app in the list, tap it, and change the alert style from Silent to Sound and vibration. This restores the notification sound for that app only.

Here are the steps in full:

Open the Settings app on your Samsung phone.
Tap Notifications.
Tap App notifications to see a full list of your installed apps.
Find the app whose notifications are silent and tap it.
Look for the alert style or notification category. You will see options such as Sound and vibration, Sound only, Vibration only, and Silent.
Select Sound and vibration or Sound only, depending on your preference.
Go back and test by sending yourself a notification from that app.

Some apps, particularly messaging and email apps, have multiple notification categories. For example, your messages app might have separate categories for individual chats and group chats. If only some messages are silent, check each category within the app's notification settings and update them individually.

How do you turn off silent notifications for all apps at once?

There is no single toggle on Samsung phones that turns off silent notifications for every app at once, because each app's alert style is stored individually. However, you can work through the list efficiently by filtering your notifications to show only apps currently set to silent, then updating them one by one.

Here is the quickest way to do it:

Open Settings and tap Notifications.
Tap App notifications.
At the top of the screen, tap the filter or sort option and select Silent. This shows only the apps currently set to deliver silent notifications.
Work through each app in the list, tapping it and changing the alert style to Sound and vibration.

Depending on how many apps are set to silent, this could take a few minutes, but filtering the list first saves you from scrolling through every app on your phone. Once you have updated each app, your notification sounds should be restored across the board.

If you want to prevent apps from being moved to silent in the future, check whether Samsung's adaptive notification feature is active. You can find this option in Settings under Notifications. Turning it off means One UI will no longer automatically silence apps based on your usage habits.

Why do notifications go silent again after I change the settings?

If your notifications keep going silent after you change them, the most likely cause is Samsung's adaptive notifications feature. This One UI setting automatically moves apps to silent if you frequently dismiss their notifications without interacting with them. It is designed to reduce clutter, but it can feel like your settings are being reset without your permission.

Other reasons notifications may revert to silent include:

Adaptive notifications is enabled: Go to Settings, tap Notifications, and look for Adaptive notifications or Notification suggestions. Turn this off to stop One UI from automatically silencing apps.
The app itself is overriding your settings: Some apps have their own internal notification settings that can conflict with your phone's settings. Open the app, go into its own settings menu, and check whether notifications are enabled there as well.
A recent software update reset your preferences: This is less common, but One UI updates can occasionally affect notification settings. If it happened right after an update, go back through your notification settings and reconfigure the apps that changed.
Battery optimisation is interfering: Samsung's battery optimisation feature can restrict background activity for apps, which sometimes affects how and when notifications are delivered. Go to Settings, tap Battery and device care, then Battery, and check whether the affected app is being restricted.

Turning off adaptive notifications is usually the fix that solves the problem for good. Once that setting is off, your notification sound preferences should stay exactly as you set them.

Frequently Asked Questions

How do I stop Samsung from automatically silencing newly installed apps?

To prevent One UI from silencing new apps by default, go to Settings, tap Notifications, and disable Adaptive notifications. With this setting off, Samsung will no longer automatically change an app's alert style based on your usage habits, meaning every newly installed app will keep whatever notification settings it launches with. You may still want to manually check each new app's alert style after installing it, since some apps set themselves to silent by default regardless of this setting.

Can I change notification settings directly from the notification shade without going into Settings?

Yes. On Samsung phones running One UI, you can long-press on a notification in the notification shade to bring up a quick settings shortcut for that app's alerts. From there, you can switch the alert style between Silent and Sound and vibration without opening the full Settings menu. This is the fastest option when you notice a specific app is silent and want to fix it on the spot.

My notification sounds are back but they're very quiet — how do I fix that?

This is usually a volume issue rather than a silent notification issue. Open Settings, tap Sounds and vibration, then Volume, and check that your Notification volume slider is turned up. It is worth noting that Samsung keeps notification volume and ringtone volume as separate sliders, so your ringtone can be loud while notifications remain nearly inaudible. Also confirm that the notification sound assigned to the app has not been changed to a very short or quiet tone.

Does battery optimisation actually stop notifications from making sounds, or does it block them entirely?

Battery optimisation can do both, depending on how aggressively it restricts an app. In some cases it delays or batches notifications so they arrive late and out of order. In other cases it can suppress them entirely while the app is in the background. To check, go to Settings, tap Battery and device care, then Battery, and select Background usage limits or App power management. Make sure apps you rely on for timely alerts are set to Unrestricted rather than Optimised or Restricted.

What should I do if an app's notification settings are greyed out and I can't change them?

Greyed-out notification settings usually mean the app has been restricted at a system level, often because it is a work profile app, a managed device app, or because it has been put into a deep sleep state by Samsung's device care features. First, check Settings under Battery and device care to see if the app is in the Sleeping apps or Deep sleeping apps list and remove it from there. If your phone is managed by an employer or school, the notification settings may be locked by a device policy that you cannot override without contacting your IT administrator.

Will a factory reset fix persistent silent notification problems, and is it worth doing?

A factory reset is almost never necessary for silent notification issues and should be treated as a last resort. The root causes — adaptive notifications, battery optimisation, app-level settings, or a software update — can all be resolved through the Settings menu without wiping your phone. If you have worked through every setting mentioned and notifications are still reverting to silent, try clearing the cache partition first, which is a softer reset that does not erase your personal data.

Do these steps work the same way on all Samsung Galaxy models and One UI versions?

The core steps are consistent across most Samsung Galaxy phones running One UI 3 and later, but the exact labels and menu layout can vary slightly between versions. For example, older versions of One UI may show Notification categories instead of Alert style, and the Adaptive notifications toggle may appear under a slightly different name such as Notification suggestions. If you cannot find a specific option where described, use the search bar at the top of the Settings app and type the feature name to locate it quickly on your specific model.
