Users of Xiaomi, Redmi and Poco smartphones often encounter a pre-installed system application called Security Space (or “Security Space”), a virtual environment isolated from the main system, designed to store confidential files and install second copies of applications. However, for many device owners, the presence of this component is an unnecessary ballast, occupying resources and interfering with the interface.
The process of completely removing this system component is not as obvious as uninstalling a regular program from Google Play. With the standard methods available in the settings menu, the user can only clean the data or forcefully stop the process, but not erase himself. APK-Deep cleaning requires more advanced tools and structure understanding MIUI or hyperos.
In this article, we will discuss in detail the safe ways to get rid of Security Space, using both standard disablers and ADB console commands. You will learn what risks the complete removal of system packages carries and how to avoid turning a smartphone into a “brick” when working with system partitions.
What is Security Space and Why You Should Delete It
Security Space is an analogue of Second Space built into the MIUI shell, which creates a separate user profile with its own apps, gallery and settings, protected by an additional password or fingerprint, and is useful for separating work and personal life or hiding data from prying eyes.
However, many users choose to remove this component for several reasons: First, the application can run in the background, consuming RAM and battery power, even if you do not use it. Second, its icon or notifications can periodically pop up, annoying the owner. Third, advanced users often seek to “lighten” the system as much as possible by removing all bloatware.
⚠️ Note: Complete removal of system components through ADB If you plan to use the app cloning or file hiding feature in the future, it is better to simply turn off the service rather than delete it completely.
It's important to understand the difference between disabling and deleting. Disabling hides the application from the interface and prevents it from running, but the files remain on the disk. Deleting erases APK-For most scenarios, disabling a function through settings is enough to stop noticing its presence.
Preparation of the device for system modification
Before you start taking action, you need to properly prepare your Xiaomi smartphone. Data security is the number one priority. Even if you don’t plan to do a full reset, backing up important contacts and photos will never be superfluous when working with system settings.
To do the procedures, you'll need to turn on the developer mode, which is a hidden menu that allows you to manage debugging over USB and other options that are not available to the average user.
To activate the developer mode, go to Settings → About the phone and quickly press 7 times on the item "Version" MIUI» or "Version" OS». After the message “You became a developer” you can go to set up debugging.
Then you need to activate the debugging itself. Go to Settings. → Advanced settings → For developers, find the item "Debugging by USB» And turn it on. We also recommend you turn on the "Installation through" option. USB» and «USB-Debugging (security settings) if available in your firmware version.
☑️ Preparation of the Xiaomi smartphone
Disconnection through standard MIUI settings
The safest and easiest way to remove Security Space from everyday use is to disable it via the system menu, a method that does not require a connection to a computer and eliminates the risk of damage to system files.
To start, open the Security app (green lightning icon), which is the system control center in MIUI. Scroll down to the Tools or Utilities section and find the Second Space or Security Space item.
When you enter the space menu, look at the settings in the top right corner (usually a gear icon or three dots), and there should be a button called "Delete second space" or "Switch off," and the system will request confirmation and warn that all data inside the isolated profile will be irretrievably lost.
- 📱 Open the Security app on the home screen.
- 🔍 Find and select the "Second Space" section».
- ⚙️ Click on the settings icon and select “Delete space».
- ✅ Confirm the action by entering the screen unlock password.
Once you do that, the icon will disappear and the Second Space processes will be stopped, and if your goal is to just free the interface from the extra elements, then you can stop at that point.
💡
If after removing the space, the app icon remains in the list of installed programs, try clearing the Security app cache through the application management menu.
Complete removal via ADB (for advanced users)
If a standard shutdown doesn’t meet your requirements and you want to physically remove a packet from the system, you’ll need a computer and an Android Debug Bridge (ADB) toolkit, which allows you to manage system packets without superuser rights.
First, install the drivers for your device and the SDK Platform Tools platform on your PC. Connect your smartphone with a cable to your computer and allow debugging in a pop-up window on your phone screen. Open the command prompt or terminal in the ADB folder and check the connection with the adb devices command.
Deletion requires knowing the exact name of the package. In the case of Security Space, it varies a lot, but the main one is com.miui.securitycenter (which contains space modules) or specific components like com.miui.secondspace. Be extremely careful: removing the wrong package can lead to a cyclic reboot.
adb shell pm uninstall -k --user 0 com.miui.secondspaceExecuting this command will remove the application for the current user, it will disappear from the system, but it will remain in the recovery section in case of resetting to factory settings, which is the most secure method of "delete" because it is reversible.
⚠️ Warning: Do not delete the entire com.miui.securitycenter package unless you are sure of the consequences.This is the main security module, responsible for antivirus, memory cleaning and call filtering.
To return a remote application, use the command: adb shell cmd package install-existing com.miui.secondspace. This will restore the component to its original state.
Comparison of System Cleaning Methods
The choice of method depends on your goals and level of training. Below is a table to help determine which method is right for you. Each option has its advantages and disadvantages, which should be considered before starting the procedure.
| Method | Difficulty | Risk to the system | Reversibility |
|---|---|---|---|
| Disconnection in settings | Low. | Absent. | Complete. |
| Removal via ADB (User 0) | Medium | Minimum | Restored by the team |
| Root-deletion of system files | Tall. | High-pitched | Just reflashing. |
| Use of Debloat scripts | Medium | Medium. | Depends on the script. |
As you can see from the table, for 95% of users, the best solution is the first or second method. Using Root rights to delete Security Space system files is only justified in cases of customization of ROM or deep optimization, where every megabyte of memory is in the account.
Automated scripts to remove bloatware (like Universal Debloater) can be handy, but they often work on a template and can remove excess.Always check the list of packets the script is going to remove before confirming the action.
Possible problems and solutions
Unforeseen situations can occur when you manipulate Xiaomi system components, and one of the common problems is that you get bugs when you run other security applications or you can't clear the cache, which can happen if you delete dependent libraries.
If the phone starts to behave strangely after removing the component (sound disappears, the camera does not work or settings are reset), the first thing you should do is reset the application settings through the recovery menu. If this does not help, you will need a full reset (Wipe Data) or flash the device through the Mi Flash Tool.
What to do if your phone is in Bootloop?
Users also sometimes complain that the Security app stops updating or gives out bugs when checking for viruses, a direct consequence of removing key Security Center modules, in which case the only way out is to reinstall system applications via ADB or reset to factory settings.
- 🔄 Reboot the device after any manipulations ADB.
- 🛠 Use only official drivers and tools from Xiaomi.
- 💾 Keep a list of deleted packets to know what to recover.
Remember that MIUI or HyperOS updates can automatically restore remote system components, so after a major software update, the verification and removal procedure may need to be repeated.
Alternatives and data security
By removing Security Space, users often look for alternatives to protect their data. Modern versions of Android and MIUI have built-in features like App Hiding or Password Protection that allow them to achieve similar results without creating a separate virtual environment.
To hide application icons, use the Hide Apps feature in the theme settings or in the Security app. To protect specific programs (messengers, galleries) enable Application Protection and set a separate password or use biometrics.
If you want complete isolation, consider using third-party container apps like Shelter or Island.They use the Jobs profile on Android, creating a robust, isolated environment that can be frozen or removed at any time without affecting the main system.
💡
Using third-party containers (Shelter/Island) gives more control over data isolation than built-in Security Space and allows you to easily delete the entire profile at once.
Keep in mind that data security depends not only on isolation, but also on the general hygiene of smartphone use: installing updates, using complex passwords, and being careful when installing apps from unknown sources.
