Owners of budget smartphones like the Xiaomi Redmi 9A often encounter intrusive system applications that cannot be removed by standard methods.One of the most annoying components of the MIUI shell is an embedded antivirus and optimizer known as "Security." It consumes CPU resources, drains the battery and constantly issues advertising notifications, preventing comfortable use of the gadget.
Users are wondering if it is possible to get rid of this built-in software without losing warranty or risk turning the device into a brick. The process of removing or, more correctly, forcing the system component to stop and hide requires careful attention. In this article, we will discuss in detail the safe and advanced methods of solving the problem that are relevant for current versions of firmware.
It is important to understand that system applications are deeply integrated into the Android operating system. Simply removing the icon from the desktop does not solve the problem, since processes continue to work in the background. To really free up memory and improve the performance of the Redmi 9A, more radical measures need to be applied, which will be discussed below.
Why Security Apps Cannot Be Removed in the Normal Way
MIUI architecture is designed to protect critical components from being removed by the user. The security app in Xiaomi is a task manager, antivirus and permission center, and the system considers it vital, so the "Delete" button in the application management menu is simply inactive or hidden.
Attempts to simply disable an application through standard settings often fail. The "disable" button can be gray, and the system will issue warnings that this may lead to unstable operation of the device. It is a mechanism for protecting against accidental damage to the system, but it also limits the freedom of action of experienced users.
⚠️ Warning: Forced removal of system components without proper preparation can lead to a cyclical smartphone restart (bootloop).Always back up data before you start manipulating.
Xiaomi is also actively implementing its monetization services, and the security app is one of the channels for delivering ads, so developers are doing their best to make it harder to deactivate it, and understanding these limitations helps you choose the right tool to bypass them.
- 🛡️ System protection: The system kernel blocks the removal of critical packets through the standard interface.
- 📢 Advertising integration: The application serves as a platform for displaying recommendations and news in the MIUI.
- 🔄 Service dependency: Some phone features may link to the library of this app.
Redmi 9A Prepares for System Component Removal
Before you start using the deletion tools, you need to properly prepare the device. The first step is to turn on the developer mode, because without it, access to debugging via USB will be closed, which is standard procedure for any deep interaction with Android.
To activate the desired functions go to Settings → About the phone and find the line "Version" MIUI". You need to press it quickly. 7-10 Once in a row, until the message "You became a developer" appears, and then a new option will appear in the settings menu "Additional" or "Extended settings", where you need to find "Developers".
Inside the developer menu, you should find and activate the USB Debugging Switch. When you connect your smartphone to your computer, you'll see a request for debugging permission on the screen -- be sure to tick "Always Allow" and confirm the action. Without this step, the computer won't be able to send commands to delete packets.
☑️ Checklist of smartphone preparation
It is also recommended to disable all antiviruses on your computer, if any, as they can block the operation of specialized utilities for managing Android.
Delete method via ADB on a computer (No Root)
The safest and most effective way to get rid of the Security app on Redmi 9A is to use the Android debugging bridge (ADB), a method that does not require superuser rights and allows you to delete packets for the current user, effectively hiding them from the system.
To get started, you will need to download the SDK Platform Tools package from the official Google website or use the ready-made Minimal ADB and Fastboot builds. After unpacking the archive, open the command prompt (CMD) or PowerShell in the folder with the utility. Connect the phone with a cable to the PC.
adb devicesEnter adb devices in the terminal. If you see your device's serial number and your device's "device" status, you've got the connection. If you're "unauthorized," look at your phone's screen and confirm the debugging request.
Next, you need to know the exact name of the security application package, which usually looks like com.miui.securitycenter.
adb shell pm uninstall -k --user 0 com.miui.securitycenterOnce the command is executed, the application icon will disappear and the processes will stop. It is important to note that these applications are not deleted completely from the disk, but stop loading the system, which allows you to return everything at any time by resetting the settings.
Use of Xiaomi ADB/Fastboot Tools
For those who are afraid to work with the command line, there is a great graphics solution – Xiaomi ADB/Fastboot Tools.This program, developed by Szaki enthusiast, automatically detects a connected device and offers a list of system applications to remove.
The software itself finds the packages it needs and labels them as safe to remove, and you look for Security or MIUI Security and click Uninstall, and the interface is clear to the beginner, and the risk of entering the wrong command is reduced to zero.
| Parameter | ADB (Command Line) | Xiaomi ADB Tools |
|---|---|---|
| Difficulty | High (you need to know the commands) | Low (graphic interface) |
| Risk of error | Medium (human factor) | Minimum |
| Speed of operation | Quickly. | Average (list loading) |
| Requirements | PC and cable only | Java Runtime Environment |
When using the utility, the included debugging is also required. USB. The program will automatically install the necessary drivers if they are not in the system. ADB/Fastboot Tools is preferred by most Redmi users 9A.
Removal with Root rights and system managers
Xiaomi Redmi 9A owners who unlock the bootloader and get SuperUser (Root) rights have full control over the file system, and for them, removing system debris becomes a trivial task, available directly from the smartphone screen.
The most popular tool for this purpose is System App Remover or SD Maid, which requires the granting of superuser rights on the first run, and once accessed, they display a complete list of all packages, including hidden system packages.
Search the Security Center list and select the option to either Delete or Freeze. Freeze is a safer option, as it simply prevents the application from running, but does not erase its files from the /system partition.
⚠️ Note: Getting Root Rights to Redmi 9A Requires unlocking the bootloader through Xiaomi servers, resulting in a complete data reset and waiting 3 to 7 days.
Root rights open up opportunities, but they also increase system vulnerability, and banking applications can stop working because of the detection of a modified system, unless special masking tools like Magisk Hide are used.
- 🔓 Full access: Ability to delete any files from the system partition.
- ⚙️ Flexibility: Installation of modules for deep customization of the interface.
- ⚠️ Risks: The possibility of loss of guarantee and unstable operation of some banking services.
Possible problems and solutions
Once you delete the Security app, users may experience a number of side effects, such as notifying them of calls or messages, because it is often the system component that filters them, and then you have to choose between cleanliness and functionality.
Sometimes, after removal, there are periodic pop-ups with "Process Stopped" errors. This is normal for the first minutes after manipulation. If the errors continue, the dependent component may have been removed, in which case the device restart helps.
In rare cases, Redmi 9A may not be able to adjust brightness or sound through standard sliders. If you encounter a critical error, you can always return the deleted packet via ADB command:
adb shell cmd package install-existing com.miui.securitycenterThis reinstal command will packet from the system's hidden storage, returning everything as it was, so ADB is considered reversible and secure, unlike direct file removal through a Root Explorer.
