How to Remove the Personal Security App on Xiaomi

Owners of Xiaomi, Redmi and Poco smartphones often encounter an intrusive system component called “Personal Security” in the Russian-language shell of MIUI or HyperOS. This application, known worldwide as Security, is a deeply integrated operating system module responsible for antivirus protection, memory cleaning, resolution management and blocking unwanted calls. Many users perceive it as excessive software that consumes resources, shows advertising and does not give full control over the device, so the desire to completely get rid of it is quite natural.

However, the standard methods available through the normal settings interface cannot remove this system package. The “Delete” button in the application management menu is either missing or inactive, since Android protects critical components from accidental removal by the user. Uninstallation or forced disabling requires the use of more advanced tools such as ADB (Android Debug Bridge), or obtaining Root rights, which can be risky for inexperienced users.

In this article, we will discuss in detail how to safely remove or disable the Personal Security app without having to flash the device. We will look at the most reliable method of using the computer and command line, and discuss the consequences of completely removing the system component for the stability of MIUI. Understanding the structure of system processes will help you make an informed decision about whether to completely remove the application or configure it correctly.

The role of the application Personal security in the MIUI system

The Security app (com.miui.securitycenter) is not just an antivirus, but a central control hub in Xiaomi shells, which controls the task manager, manages permissions for other applications, provides Second Space and app cloning functions. It is this component that is responsible for the famous “green button” of memory cleaning, which users press daily. Deleting this module can lead to unstable interface operation, since many system processes are tied to its libraries.

The main reason users are seeking to remove Personal Security is because of the company’s aggressive monetization policy.The app often displays advertisements, recommends installing additional software from the GetApps store, and periodically runs a system scan while consuming battery power. In addition, built-in antivirus based on Avast or AVL engines does not always perform better in independent tests compared to specialized solutions, while remaining an undeleteable system load.

It is important to understand the difference between complete deletion and disabling. Complete deletion via ADB physically erases the packet from the system, making it impossible to run it until the flashing time. Disabling simply prevents the application from starting and displaying in the interface, but its files remain in the system partition. For most users, disabling functionality through settings or freezing through ADB will be enough to achieve comfort.

⚠️ Note: Complete removal of the Personal Security system application may result in the inability to install new programs from unknown sources, as this component requests and controls the appropriate permissions in the system. MIUI.

Preparing a smartphone to remove system applications

Before you start manipulating system files, you need to properly prepare the device. The first step is to activate the developer mode, which is hidden by default. To do this, open Settings, go to About Phone and find Version. MIUI (or OS). You need to press this paragraph quickly. 7-10 once in a row, until a pop-up notice appears that you have become a developer.

Then you should turn on USB debugging. Go to Settings → Additional → For developers. Find the USB debugging switch and activate it. Also, in this menu, you should find Install via USB and Debug via USB (security only), but basic debugging is often enough to work with ADB. When you connect to your computer, your phone will ask for debugging permission - be sure to confirm it by ticking "Always allow from this computer."

To work, you will need a computer running Windows, macOS or Linux, as well as a serviceable one. USB-You need to install a minimum set of tools on your computer, Google Platform Tools, which contains adb and fastboot executables. Without this software package, deep-level interaction with the phone's file system will be impossible. Make sure your smartphone battery is at least 50% charged to avoid suddenly shutting down during operation.

Removal via ADB: step-by-step instructions

The most effective and safe way to get rid of Personal Security is to use the ADB command line. This method does not require superuser rights (Root) and allows you to remove applications for the current user without affecting the Recovery system partition, which saves the ability to restore factory settings in the future. First connect your smartphone to your PC and open the command prompt (or terminal) in the folder with the ADB installed.

Check the connection by entering the adb device command. The phone screen should show a window requesting permission to connect — click "Allow." If the list shows the serial number of a device with device status, then the connection is established. Now you need to know the exact name of the package that we plan to remove. For the application "Personal Security" in global firmware, it usually looks like com.miui.securitycenter.

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

Executing this command will remove the application for the main user (user 0). The terminal should appear a message Success. After that, the application icon will disappear from the desktop, and the processes associated with it will cease to start. If you want to return the application, you will need to execute the command adb shell cmd package install-existing com.miui.securitycenter or simply reset the phone to factory settings.

💡

Before removing any system package through ADB, write its exact name in a notebook, which will allow you to quickly restore functionality if critical system errors occur after removal.

Alternative methods: freezing and third-party utilities

If you find using the command line too difficult or risky, you can use ADB graphical shells such as Xiaomi ADB/Fastboot Tools or Universal Android Debloater. These programs automatically identify the connected device and offer a list of system applications with recommendations for their removal. In the interface of such gates, "Personal Security" is usually marked as "Safe to remove" (Safe to remove), which reduces the risk of error.

Another option is to use freezer applications like Ice Box or Shizuku in conjunction with Canta, which allow applications to freeze, depriving them of the ability to run processes and consume resources, effectively turning them into inactive files. The method works without root rights if you configure Shizuku via wireless debugging, which is a modern alternative to the classic wired ADB.

There is also a myth about the possibility of deleting through the "Special Features" menu. Some users try to assign an action for long button presses or use macros, but this does not remove the application, but only limits its interaction with the interface.

Consequences of disposal and possible problems

Once you remove Security Center, you may face a number of limitations, most notably the built-in virus scanner when installing applications and scanning. QR-It also eliminates the ability to control permissions through the standard menu. MIUI, Although basic Android settings will remain available, in some cases, the "Second Space" and the app hiding feature may stop working.

One of the common problems is the occurrence of errors when updating the system or verifying the integrity of components. Since Personal Security checks the signatures of other system applications, its absence can be interpreted by the system as a violation of integrity. This is not critical for everyday use, but can cause periodic pop-up notifications or disruptions in the GetApps store.

Importantly, removing this app does not affect the performance of Google Play Protect, which continues to function independently of the manufacturers’ shells, so you will still have a basic level of protection against malware, but the garbage cleaning and memory optimization features will have to be replaced with third-party solutions such as Files by Google or SD Maid.

Setup and Optimization without Complete Deletion

If you're not prepared for radical measures, you can significantly reduce the intrusiveness of Personal Security by setting it up correctly. Go to the app, click on the settings gear, and turn off all items related to Getting Recommendations, Ads, and Automatic Base Update, which will remove most annoying notifications.

Also, limit the background activity of the application. Go to Settings → Applications → All applications → Security → Activity Control. Select No restrictions (if you want the antivirus to work) or, conversely, disable autoruns if you do not need constant protection in the background. This will preserve functionality, but will eliminate constant resource consumption.

• 📱 Turn off notifications about “viruses” and “junk” in the settings of the Security app itself.
• 🔒 Disable access to location and microphone for advertising modules within the app.
• 🚫 Remove the app shortcut from your desktop if you don’t use its features daily.
• ⚡ Use Do Not Disturb mode for system applications in battery settings.

⚠️ Note: After the firmware update MIUI remotely ADB applications may return if the update includes a complete rewriting of the system partition. Be prepared to repeat the procedure or use automatic uninstallation scripts.
