How to permanently disable second-space notifications on Xiaomi: 5 working ways

Xiaomi’s second-space feature (MIUI) was originally intended as a tool to separate work and personal data, but many users are faced with the problem that even if you’re not using the second space, the system continues to send notifications about its activation, updates or “forgotten” applications. These alerts are not just annoying — they can interfere with work, especially if they appear at the most inopportune time.

In this article, we’ll look at all the ways you can disable second-space notifications on Xiaomi, Redmi, POCO and Black Shark devices, from standard MIUI settings to hidden developer settings. The instructions are relevant for the MIUI 12, MIUI 13 and MIUI 14 firmware versions, including global and Chinese builds. If you’re tired of annoying pop-ups, read on.

Why do we have second space notifications?

Before we get to the problem, it is important to understand the cause of the problem, and second-space notifications in MIUI can be activated in several scenarios:

• 🔄 Automatic synchronization: The system periodically checks the state of the second space and sends notifications if detects "inactivity" or "potential errors".
• 📱 Residual processes: Even if you delete the second space, some system services (com.miui.dualspace) may continue to run in the background.
• 🔒 Security MIUI: The firmware thinks you have “forgotten” the second space and reminds you of it as a “security function".
• 📲 Updates MIUI: After major updates (for example, with the MIUI 13 on MIUI 14) the system may reset some notification settings.

Interestingly, on some models (e.g. Xiaomi 12 Pro or POCO F5), second-space notifications appear even if the feature is disabled in the Settings menu → Special Features → Second Space. This is because MIUI handles spaces at the Android core level, rather than through standard APIs.

Method 1: Disabling notifications through application settings

The most obvious (but not always working) method is to block notifications directly in the system settings.

1. Open Settings → Applications → Application Management.
2. In the search box, type "Second Space" (or Dual Space in English firmware).
3. Select the Second Space app (the icon with two circles).
4. Go to the Notifications section.
5. Turn off the "Show Notifications" slider.

On some devices (e.g. Redmi Note 11), this method is unstable: notifications may return after a reboot.

Make a backup copy of important data

Check the version of MIUI in Settings → About the phone

Close all applications in the second space (if it is active)

Turn off automatic sync in your Google account-->

Method 2: Completely remove the second space (for power users)

If you don't use the second space and want to get rid of it forever, you can remove the system components that are responsible for this function.Warning: this method requires root rights or ADB use and can lead to unstable system operation if executed incorrectly.

Instructions via ADB (without root):

1. Activate USB debugging in Settings → About Phone → MIUI version (click 7 times), then go back to Settings → Additional → For Developers.
2. Connect your phone to your PC and execute the command: adb shell pm uninstall --user 0 com.miui.dualspace
3. HyperOS models (e.g. Xiaomi 14) may require an additional command: adb shell pm uninstall --user 0 com.miui.dualspace.stub

After these commands are executed, the second space will disappear from the settings menu, and notifications will no longer appear.

Method 3: Disconnection through "Special Opportunities"

In some versions of MIUI (especially on POCO and Black Shark), second-space notifications are managed via a special feature menu, a technique less well known but often works where standard settings are powerless.

Follow the instructions:

1. Open the Settings. → Special facilities.
2. Scroll down and find the System Settings section.
3. Select the Second Space (which can be called Dual Apps or Parallel Space).
4. Turn off the slider "Show notifications" or "Sync data".
5. Save the changes and restart the device.

On Xiaomi 13 Ultra and other flagships, this section can be hidden. To see it, pre-activate the developer mode (as in Method 2).

💡

If the "Second Space" section doesn't appear in Special Options, try changing your phone region to India in Settings → Additional → Region. This section is often available on Indian MIUI firmware.

Method 4: Block notifications via Security

The MIUI Security app controls many of the system alerts, including those associated with the second space. Here's how to block them through this module:

1. Open the Security app (the shield icon).
2. Go to Notification Manager (or Notification Manager).
3. Find the second space or dual space.
4. Turn off all the switches associated with notifications (including Sound, Vibration, and Pop-ups).
5. Return to the main Security menu and clear the app cache.

This method is particularly effective on devices with MIUI 14, where second-space notifications are often disguised as "system alerts." If notifications continue to appear after these actions, check the Autorun section of the same Security app and disable Autorun for Second Space.

Method 5: Resetting notification settings (last resort)

If none of these methods worked, the radical solution is to reset all notification settings, which would bring all alerts back to factory settings, but eliminate the intrusive pop-ups of the second space.

How to do this:

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 (a password or pattern lock may be required).
4. After resetting manually disable notifications for Second Space (as in Method 1).

This method is also useful if second-space notifications appear after a firmware update.Reset removes all user rules for alerts, including those that may have been corrupted during the update.

💡

Resetting notification settings does not affect personal data (photos, messages, applications), but will return all permissions and alerts to factory values. After the procedure, it is recommended to manually configure notifications for key applications (messengers, mail, etc.).

Compatibility table with Xiaomi models

Not all methods work equally well across devices, and below is the compatibility table for popular models:

If your model isn’t in the table, try the methods in order: Method 4 → Method 3 → Method 2. New HyperOS devices (e.g. Xiaomi 14) may require a combination of several methods.

Frequent Mistakes and How to Avoid Them

When you turn off the second space notifications, users often encounter typical problems, and here are the most common ones and how to solve them:

• 🔄 "Notifications are returned after rebooting": This means that the com.miui.dualspace system application automatically restarts.Solution: Use Method 2 (ADB) or disable auto-start in the "Security" app".
• 🔒 "No access to second space settings": "Some firmware (e.g. Chinese) has this section hidden. Solution: change region to India or Global in settings.
• ⚠️ "After removing the second space, some features stopped working": This is possible if you deleted the associated system components (e.g. com.miui.dualspace.stub).Solution: restore the application via the command: adb shell cmd package install-existing com.miui.dualspace
• 📱 "Notifications come, but there is no second space in the settings": This means that the alerts are generated by another service (e.g. MiuiSystemUI).Solution: use Method 4 (lock through "Security").

If none of the methods worked, check if your device has custom MIUI themes installed. Some themes modify system notifications, which can cause crashes. Try returning the standard theme to Settings → Screen → Themes.

💡

Forums often advise you to disable second-space notifications via ##4636## (test menu) which does not work for MIUI and can cause system services to crash. Don't use it!
