Removing the app Security on Xiaomi Redmi 9: Real ways

Many Xiaomi smartphone owners are faced with the desire to clean the system of preinstalled software, which seems to them unnecessary. In particular, on the Redmi 9 model, users often wonder how to remove the Security application, since it is deeply embedded in the shell of MIUI. However, it is worth noting immediately an important technical fact: this system application is the core of the Android operating system on devices of this brand, so standard removal through settings is impossible.

However, there are proven methods to either completely uninstall the admin component or, more safely, hide it and disable background activity. In this guide, we will detail all available options, including the use of the appliance. ADB-commands and standard interface customization tools so you can choose the most suitable for your level of training.

Before you start taking action, you need to understand that the system application is responsible not only for antivirus protection, but also for the memory cleaner, call blocker and battery optimizer. Incorrect interference with this module can lead to instability of the Redmi 9, so carefully follow the instructions and weigh the risks.

Why Security Apps Cannot Be Removed in the Standard Way

The MIUI shell installed on Redmi 9 has a rigid dependency structure, where the Security app acts as a central node. If you try to find the Remove button in the application management menu, you will see only the option to turn off updates or stop, but not the complete uninstallation. This is done by Xiaomi developers intentionally, because many system processes are tied to the library of this component.

Trying to remove a system package without special rights or tools will only lead to a system error telling you that the action is not available. The user interface simply does not provide such an opportunity for mission-critical components, which includes com.miui.securitycenter.

It is also important to note that the absence of a deletion button is not a bug, but a security mechanism that prevents accidental damage to the system by inexperienced users who may not be aware of the consequences of disabling security and optimization services.

⚠️ Note: Complete removal of system components through ADB It can cause loss of warranty and, in rare cases, a cyclical device reboot (bootloop) if critical dependencies are affected.

Preparing the Redmi 9 smartphone for profound changes

Before you start manipulating system files or using debugging, you need to properly prepare your Redmi 9. First of all, make a full backup of important data, as any changes to the system partition carry potential risks.

Next, you need to activate the developer mode. To do this, go to the Settings menu, select About Phone and quickly click 7 times on the MIUI version. After the notification “You became a developer”, go back to the main settings menu and find the Additional (or Advanced Settings) section where the Developers item will appear.

Inside the developer menu, find the USB Debugging Switch and activate it. The system will alert you to the risks of confirming the action. It is also recommended to enable the option “Do not turn off the screen” when you connect the charging so that the process does not interrupt due to the transition to sleep mode.

Removal method via ADB and computer

The most radical and effective way to get rid of the Security app is to use the Android Debug Bridge toolkit (ADB). This method requires a computer (Windows, macOS or Linux) and USB-First you need to download the platform tools. ADB from the official website of developers and unpack them in a convenient folder.

Connect Redmi 9 to your computer with a cable. You'll see a request for debugging permission on your smartphone screen -- make sure you tick "Always Allow" and click "OK." Open the command line or terminal in the ADB folder and type in a command to check the connection:

adb devices

If a device with a serial number appears on the list, the connection is successfully installed. To remove the Security application, use the pm uninstall command with the --user 0 flag, which deletes the application only for the current user without physically affecting the system partition (which is safer):

adb shell pm uninstall -k --user 0 com.miui.securitycenter

Once you execute the command, the app icon will disappear from the desktop, and the component itself will stop loading into RAM, and if you want to return everything as it was, you will need to reset the phone to the factory settings, which reinstalls all system packages.

Alternative: Hiding and disabling without root rights

If using the computer and command line seems too difficult or risky, you can use a less radical method.You will not delete the application completely, but you will be able to hide its icon and prevent background work, which will free up the resources of Redmi 9. → Annexes → All applications.

Find in the list “Security” (or “Security”). Click on it and select the option “Disable” (if available) or “Stop.” After that, go to the desktop or theme settings. MIUI has an application hide feature: pinch the empty space on the desktop, select “Hide apps” and add a security component.

You can also restrict the application's rights. From the Security app's menu, go to settings and disable all notifications, geolocation access, and auto-start, making it virtually invisible to the user, although technically the files will remain on the disk.

💡

Use third-party launchers like Nova Launcher or Microsoft Launcher to get more flexible control over hiding system application icons without having to use ADB.

Risk analysis and impact of the system

Before you decide to delete, you need to make an objective assessment of whether it is necessary. The security app on Xiaomi is not just an antivirus. It manages permissions, call filter, cache cleaning, and even battery settings. Deleting this component can cause other system functions that depend on its libraries to stop working.

The table below compares the consequences of deleting and disabling the application:

The most critical consequence may be that permissions cannot be managed for other applications, and if you remove the security center, the system may lose the tool to request permissions to access the camera or microphone from new programs, creating a data breach.

⚠️ Note: After removing the security component, the built-in virus scanner in the GetApps app store will cease to function, which increases the risk of infection of the device when downloading software from unverified sources.

Recovery of Remote Security Component

In case you encounter an unstable Redmi 9 or interface error after uninstalling the application, the component must be returned. Since there is no standard Install button for system packages, the most reliable way is to reset to factory settings. Go to Settings → About Phone → Settings Reset → Erase all data.

This procedure will bring the phone back out of the box, reinstalling all remote system applications, including Security Center. Remember to save personal data before doing so, as they will be deleted during the reset process. The alternative, more difficult way is to flash the device through the Mi Flash Tool, but this requires a firmware file and follow the instructions accurately.

If you’ve used pm uninstall, sometimes reconnecting to ADB and commanding to reinstall helps, but it doesn’t work on all versions of Android without root permissions.
