In this article, we will discuss all possible ways to disable notifications on a locked screen: from complete concealment to selective control for individual applications. You will learn how to configure the Lock Screen through system settings, why some notifications continue to appear even after you’ve turned off, and how to get around restrictions.

If you are annoyed by pop-up banners from messengers or system alerts that prevent you from enjoying wallpaper, or you just want to increase privacy - this guide will help solve the problem once and for all. It is important to understand that MIUI is regularly updated, and the location of some menu items may vary slightly depending on the firmware version (for example, in MIUI 12.5 vs MIUI 14).

1.Why do notifications appear on the lock screen?

By default, MIUI is set to be as informative as possible: the smartphone displays notifications on the lock screen so that the user can quickly assess the importance of the message without unlocking the device.

🔹 Privacy: Messages from WhatsApp, Telegram or SMS They may contain personal information that is not desirable to be shown to others, such as bank confirmation codes or private correspondence.

🔹 Distraction: Constant pop-up banners make it difficult to focus, especially if you use your smartphone in "do not disturb" mode" (DND), But the notifications still leak onto the locked screen.

🔹 Battery and performance.Redmi Note 9 Pro display AMOLED It consumes energy even when you display a black screen with white notifications, and frequent wake-ups to display alerts reduce battery life.

In addition, some system notifications (e.g. from Mi Security or Cleaner) cannot be disabled by standard means – they are tied to MIUI services and require separate manipulations.

Method 2: Completely disabling notifications on the lock screen

The most radical method is to completely ban any alerts from displaying on a locked screen, which will hide both the content of the messages and the notification icons themselves. MIUI 12.5–14:

📌 Steps:

1. Open the settings (cog icon on the desktop).
2. Go to Always on Screen and Lock (in some versions, Lock Screen).
3. Select Notifications on the lock screen.
4. Activate the option to not show notifications.

⚠️ Warning: After that, all notifications (including missed calls and messages) will no longer appear on the lock screen. To see them, you will have to unlock your smartphone. If you only need to hide content but leave icons, read the next section.

💡 Why this method doesn’t always work?

Some Redmi Note 9 Pro users complain that after the MIUI update, settings are reset or notifications continue to appear, this is due to the fact that system applications (such as Mi Push Service) have a privileged status, in which case resetting notification settings (see section 5) will help.

Method 2: Hiding the contents of notifications (without disabling icons)

If you need to leave notification icons (to see if a new message has arrived) but hide their content, follow these steps:

📌 Instructions:

1. Go to Settings → Notifications and Status bar.
2. Select Notifications on the lock screen.
3. Activate the option to Hide the contents of notifications.
4. (Optional) Turn on the notification icons if you want to see the number of new messages.

🔹 What's gonna change?

• 📱 Instead of the text of the message, only the name of the application will be displayed (for example, "WhatsApp: 1 new message").
• 🔒 Confidential data (text) SMS, The contents of the emails will be unavailable without unlocking.
• 🔔 Notification icons will remain in the status bar (top panel).

⚠️ Note: Some messengers (e.g. Viber) ignore system settings and may display notification contents bypassing restrictions, requiring customization for each application (see Section 4).

💡

If notifications still show up after you have set up your settings, try restarting your smartphone. Sometimes MIUI caches old settings.

Method 3: Set up notifications for individual applications

You can selectively manage notifications for each app, like hiding messages from Telegram, but leaving alerts from Gmail. Here's how to do this:

📌 Step-by-step instruction:

1. Open Settings → Applications → Application Management.
2. Select the app you want (such as WhatsApp).
3. Go to the Notifications section.
4. Turn off the switch Show on the lock screen.
5. (Optional) Set notification priority (e.g., Important or Normal)

🔹 Examples of settings for popular applications:

⚠️ Note: For some system applications (e.g. Mi Push Service), the option to disable notifications on the lock screen may be blocked).

5. Resetting notification settings to factory

If notifications continue to appear after all the manipulations, it is possible that the MIUI settings were damaged after the update or reset, in which case a complete reset of notification settings will help:

📌 How to reset the settings:

1. Open Settings → Applications → Application Management.
2. Click on the three dots in the top right corner and select Reset App Settings.
3. Confirm the action (this won’t delete application data, only reset permissions and notifications).

🔹 What happens after the dump?

• 🔄 All individual notification settings for applications will return to factory.
• 📵 You will have to re-set priorities for messengers and other programs.
• ⚡ System notifications (e.g. from Mi Account) may reappear.

After reset, be sure to restart the smartphone - this will allow MIUI to correctly apply the new parameters.

💡

Resetting notification settings is a last resort. Before you do, try turning off notifications for problem applications manually (method 4).

Additional methods: disabling autostart and background activity

Some applications (especially system ones) ignore notification settings because they are in the background to block their activity completely:

📌 Shutting down autostart:

1. Go to Settings → Applications → Application Management.
2. Select a problem app (e.g. Mi Push Service).
3. Press Autostart and turn off the switch.
4. Go back and select Permissions → turn off Display on top of other apps.

🔹 What applications can be safely disabled?

• 📦 Mi Browser – if you do not use a standard browser.
• 📊 Mi Security - system antivirus, often sends unnecessary alerts.
• 🔔 Mi Push Service – is responsible for push notifications, but disabling it may disrupt some services.

⚠️ Warning: Disabling autoruns for system applications (such as Android System or Google Play Services) can cause your smartphone to run unstable, only if you know exactly what the app is responsible for.

💡 Alternatively, use No Sound mode (not to be confused with Don't Disturb!) It turns off all notifications except alarm clocks, but doesn't block them from displaying on the screen:

1. Swipe down from the top edge of the screen to open the notification bar.
2. Hold your finger on the No Sound badge (cross-out bell).
3. Choose No Sound instead of No Disturb.

7 Problems and Solutions: Why Do Notifications Disappear?

Even after all the settings, some notifications may continue to appear, and consider the typical reasons and ways to eliminate them:

🔹 Reason 1: Update MIUI reset

After major upgrades (e.g., from MIUI 12 to MIUI 13), system settings can return to factory settings. Solution: Re-apply the settings from sections 2-4.

🔹 Reason 2: The application has administrator rights

Some programs (such as Truecaller or enterprise messengers) request device administrator rights, allowing them to bypass notification restrictions.

1. Go to Settings → Passwords and Security → Privileged Access.
2. Turn off administrator rights for suspicious applications.

🔹 Reason 3: Do Not Disturb mode is enabled with exceptions

If the DND settings allow notifications from certain contacts or applications to be displayed, they will appear on the lock screen.

1. Open Settings → Sound and vibration → Do not disturb.
2. Check the Exclusions section and remove unnecessary ones.

🔹 Reason 4: Virus or malware

Some adver applications can simulate system notifications Solution: Check your smartphone with Malwarebytes or built-in Mi Security (pre-updating the databases).

💡

If the problem persists, try creating a new user in Settings → System → Multiplayer mode and check if notifications appear in a clean profile.

8. Alternative solutions: third-party applications and firmware

If standard methods don't work, you can use third-party tools, but remember that this is potentially dangerous to system stability.

🔹 Notification management applications:

• 🛡️ Notification History Log – keeps a log of notifications and allows you to block them retroactively.
• 🔕 AutoNotification (requires root) – flexible notification management via Tasker.
• 📵 Disable Notifications – Disables notifications for system applications without root rights.

🔹 Custom firmware
