To stop every alert from one app on a recent Galaxy phone or tablet, open Settings > Notifications > App notifications, select the app, then switch off Allow notifications. If you want to keep some alerts from that app, use its notification categories instead. For a temporary quiet period or private lock screen, use Do not disturb or hide notification content rather than disabling alerts altogether.
Turn off notifications from one app
- Open Settings.
- Tap Notifications, then App notifications.
- Select the app that is sending alerts you do not want.
- Switch off Allow notifications.
This is the One UI 7 route documented by Samsung US. It disables that app’s notifications on the device; it does not establish that the app’s messages or other service activity will stop. Samsung notes that menus can vary with the device and software version, so search Settings for “notifications” if these labels do not match your screen. Samsung’s One UI 7 instructions and its notification troubleshooting guidance describe those differences.

Keep useful alerts and silence only certain types
If an app sends both useful and distracting alerts, leave its main notification switch on and look for Notification categories in that app’s settings. Turn off only the categories you do not need. The available categories and controls depend on the app and software version; Samsung’s One UI 7 guidance describes this narrower option but does not promise identical controls for every app. See Samsung’s One UI 7 notification settings.

| What you want | Use | Scope and duration |
|---|---|---|
| Stop one app’s alerts | Settings > Notifications > App notifications > app > Allow notifications off | One app; remains off until you change it. |
| Silence certain kinds of alerts from an app | That app’s Notification categories, where available | Selected categories; remains configured until changed. |
| Quiet notifications for a period or on a schedule | Settings > Notifications > Do not disturb | Broad, temporary silencing, with configurable exceptions. |
| Keep alerts but conceal their details on the lock screen | Lock-screen notification content controls | Changes what is shown on the lock screen, not whether alerts are allowed. |
Use Do not disturb for a quiet period
Open Settings > Notifications > Do not disturb to silence notifications while the mode is active. Samsung says you can configure exceptions for people, apps and alarms, and set schedules. This is a better fit for a meeting, sleep or a short break than switching off app notifications one by one. For more detail, see Samsung’s guide to sounds, vibrations and notifications.

Hide previews without turning alerts off
If your concern is someone reading private details from your lock screen, keep notifications enabled and change what their previews reveal. Samsung’s One UI 8 guidance describes a global Hide content while locked control and per-app Show or hide content when locked options. The exact labels and placement may differ by device or rollout. Samsung’s Saudi Arabia page also documents per-app Brief and Detailed pop-up styles in One UI 8. Read Samsung’s One UI 8 notification guide and its One UI 8 overview.
If the settings look different or alerts still appear
- Look for the setting by name: Search Settings for “notifications” if the path or labels differ. Samsung says Galaxy menus vary by model and software version.
- Check the specific app: Return to Settings > Notifications > App notifications, select the app and confirm whether Allow notifications is off, or whether only certain categories were disabled.
- Identify what you meant to change: If alerts should still arrive but without a sound, while you are using Do not disturb, or without lock-screen details, use the corresponding sound, Do not disturb or lock-screen controls instead of turning off all app notifications.
Samsung’s troubleshooting guide for missing notifications or sound also cautions that steps vary by model and One UI version.
