Owners of Xiaomi, Redmi and Poco smartphones often face system notifications that cause confusion. One of the most mysterious components is the so-called “security element” or “Security Element”, which users notice in settings, application manager or when checking the device for viruses, but do not always understand what this module is responsible for.
It is not just an abstract term, but a specific software or hardware component built into the shell. MIUI It's called HyperOS. It's responsible for encrypting data, for working. NFC-If you notice a high load on this process or errors in its operation, you should not ignore this, as this can affect the stability of the gadget.
In this article, we will look at where this item is physically and programmatically located, how it interacts with other services, and why removing or disabling it can cause important features to fail.
What is the security element in the Xiaomi ecosystem?
The security element is a specialized module that can be implemented both software and hardware. In the context of the software shell, MIUI is a system process that oversees the operation of the antivirus, threat scanner and permission manager. It constantly monitors running applications for suspicious activity.
Technically, this component is closely related to the Trusted Execution Environment (TEE), an isolated environment within the processor that stores biometrics, passwords and encryption keys, which is why the security element has deep access rights to the system and cannot be simply removed by the user.
It's important to understand that depending on the firmware version, the name of the process can vary: in older versions it could be simply called "Security", in newer versions it was integrated into the system services of com.miui.securitycenter, its main task is to ensure that no application will access critical data without your knowledge.
⚠️ Warning: Attempting to forcefully stop this process through an engineering menu could cause a failure in the fingerprint scanner and Facebook ID.
It's not just about security, it's also about Second Space and hidden folders, and if you use those features, the security element actively encrypts and decrypts data in real time, which can put extra strain on the processor when you're actively using it.
Where to find an item in the settings and application manager
For the average user, the most accessible place to see how this component works is the standard "Security" app (lightning icon), which is pre-installed on all the devices of the brand, and this is where the visual shell for controlling the security element is located.
To get to the details, you need to go to the settings of the app itself. Usually the path is this: open the Security app, click on the three dots in the upper right corner and select Settings, and here you will find sections related to antivirus, optimization and permissions.
If you're interested in a system process, you can find it in the About Phone menu. Click the MIUI version several times in a row to activate the extended menu, then go to Memory Use or Statistics. In the process list, look for Security Center or com.miui.securitycenter.
In some cases, especially on global firmware versions, direct access to security logs may be limited, but through the Developer Menu, you can run a profiler and see the activity of this process in real time, which is useful for diagnosing autonomy problems.
Technical paths: location of system files
For advanced users with root rights or using ADB (Android Debug Bridge), the security element interface is available, and the component files are physically located in the system partition of memory, which is not accessible by default.
Major executable files and libraries are on the way /system/priv-app/SecurityCenter/. It's stored here. APK-Changing or deleting files in this directory without proper qualification will result in a bootloop (cyclic reboot) of the device.
Also worth mentioning are native libraries, which are often part of a security element, which can be located in /system/lib64/ or /vendor/lib64/ and have names related to encryption or biometrics, and are responsible for low-level interaction with hardware.
Can I delete the security files?
When you use ADB commands to analyze, you can upload a list of all security-related services that are running. The adb shell dumpsys activity services command will show you active services. Look for lines that contain miui and security.
Interaction with NFC and payment systems
Special attention should be paid to the connection of the security element with the NFC module. In Xiaomi smartphones, this component often controls the secure element (Secure Element - SE) of the chip, which stores tokenized data of your bank cards.
When you bring your phone to a terminal for payment via Google Pay or Mi Pay, the security element checks the authenticity of the request, locks the screen (if required), and transmits an encrypted token.If this module is not working correctly, the payment may not pass, or the terminal may not see the device.
NFC settings often have a Security Element or Security Element option where you can choose which component to use to emulate the card (usually HCE or embedded chip), and automatically determine by default, and you should not change this unnecessarily.
💡
If your NFC payment stops working, try changing the Security Element to Built-in Secure Element in the NFC settings and then returning it back to Automatic. This often resets the connection error.
In addition, the security element controls the access of applications to NFC-If an application tries to read a tag in the background, it is this module that can block the action or request permission from the user, preventing hidden reading of data.
Diagnostics of problems: high battery consumption and errors
One of the common reasons for using the service is the high battery consumption of the security process, which can occur if the module gets caught in a cycle of errors, constantly trying to check the file or application that has been frozen.
To diagnose the problem, go to Settings → Battery → Energy Consumption. If Security Center consumes more than 5-10% in the background without active action on your part, that's cause for concern. Normal consumption should be minimal.
A common cause of failure is conflict with newly installed applications, especially those that require deep resolutions (antiviruses from other manufacturers, memory cleaners), and Xiaomi’s security system may conflict with them in an attempt to control their activity.
☑️ Actions in case of failure of the security element
It’s also worth checking if the scanning process is running in the background. Sometimes users accidentally activate a deep cleanup or antivirus check, which can last for hours if there are many files in memory. Open the Security app and make sure there’s no active verification process.
Table: Element's main functions and statuses
To understand the role of this component in the system, we will provide a table with the main functions and their statuses, which will help you understand what tasks the security element performs in the background.
| Function | Description | Impact on the system |
|---|---|---|
| Antivirus protection | Scanning APK and running processes | Medium (active during installation) |
| Protection of payments | Monitoring the environment for Google/Mi Pay | Low (background) |
| Call filter | Blocking Spam and Fraudsters | Low (base updated) |
| Application authorizations | Control of access to camera and microphone | Minimum |
| Cleaning up memory | Completion of background processes | High (during cleaning) |
As you can see from the table, the impact on the system varies depending on the task being performed. In normal mode, the security element consumes minimal resources. However, if you notice that it loads the system constantly, then there was a failure in one of the modules.
Regular updates to virus databases and spam filters also occur through this element. Make sure that the security settings of the Security app enable automatic database updates to keep the protection up to date.
