Xiaomi’s Security App: What It Is, Why It Needs, and How to Use It

If you own a Xiaomi smartphone, you’ve probably noticed a strange icon with a shield and the words “Security”** on the list of applications. Many users do not understand what it is for, whether it can be removed and how it affects the operation of the device. In this article, we will discuss in detail what a security application on Xiaomi, what functions it performs and how to interact with it so as not to harm the system.

The Security app (or com.miui.securitycenter in the system) is a built-in tool from Xiaomi that is responsible for monitoring device status, virus protection, performance optimization and application resolution. It is part of MIUI firmware and is closely integrated with the operating system. However, not everyone knows that some of its features duplicate the capabilities of Google Play Protection, and others can even interfere with the phone if configured incorrectly.

What is the security app on Xiaomi and why you need it

The Security app is a comprehensive tool that Xiaomi has developed to protect and optimize its devices.

• 🛡️ Virus and malware protection – scans installed applications and files for threats.
• ⚡ Optimization of the system – clears the cache, closes the background processes and speeds up the smartphone.
• 🔒 Permission control – allows you to control the access of applications to contacts, camera, microphone and other data.
• 📊 Traffic monitoring – tracks which apps consume the internet and mobile data.
• 🔋 Battery management – helps to extend battery life by limiting the activity of energy-consuming applications.

It’s important to understand that this application is not antivirus in the classical sense, it is more like a security and performance management center, similar to Google Play Protection or built-in tools on smartphones of other brands (for example, Samsung Knox or Huawei Mobile Services). However, unlike them, Xiaomi’s Security** has a number of unique features associated with MIUI firmware.

One of the key features is virus scanning, which uses its own threat databases that are updated through Xiaomi servers, which means it can detect malware that Google Play Protection does not recognize. However, the effectiveness of such scanning is often questioned, with many users noting that the app finds “threats” where there are none, or, conversely, misses real dangerous files.

The main functions of the Security app and how to use them

The Security interface is divided into several tabs, each of which is responsible for a specific function.

The most useful feature is permission management, where you can manually deny applications access to data, for example, if you don't want a game to have access to your contacts or geolocation, it can be easily configured, while the optimization feature is often criticized by users because it aggressively closes down background processes, which can cause applications to restart or lose data.

Virus scanning works on the basis of Xiaomi and Avast databases (in some versions of MIUI), but its effectiveness depends on the relevance of these databases. If you haven’t updated your firmware for a long time, scanning can miss new threats, and the application sometimes mistakenly identifies secure files as malicious, especially if they were downloaded from a non-Google Play.

💡

If the Security app constantly finds “threats” in files downloaded from trusted sources (e.g., in the APK from the developer’s official website), add those files to the exceptions in the scanning settings.

Can I remove the Security app on Xiaomi?

Many users want to get rid of this app because it takes up space in memory, displays intrusive notifications or interferes with other programs, but you can’t completely uninstall the Security app without root rights, as it is a system component of MIUI.

However, there are several ways to shut down or restrict its operation:

• 🔕 Disable notifications – go to Settings → Annexes → Application management → Security → Notifications and turn off all alerts.
• ⚙️ Stop background activity – in the same settings of the application, find the Battery item → Background activity and select Limit.
• 🗑️ Remove Updates – If the app has been updated through Google Play, you can return it to the factory version by clicking Remove Updates in its settings.
• 🛠️ Use it. ADB — using commands via adb shell you can disable the application for the current user (requires a connection to the PC).

If you want to remove the app completely, you can only do this with root rights and specialized tools like Titanium Backup or Root Explorer, but this is not recommended, as it can lead to unstable system operation, errors in MIUI and even inability to update the firmware.

⚠️ Warning: Deleting system applications without understanding the consequences could make your smartphone vulnerable to attacks or cause disruptions.If you are not sure about your actions, it is better to limit yourself to turning off notifications and background activity.

How to disable unnecessary functions in the Security app

If you don't want to delete the app completely, but it's bothering you, you can turn off some features that seem redundant. Here's a step-by-step guide:

1. Open the Security app** (the shield icon).
2. Go to the Scan tab** and click on the gear in the upper right corner.
3. In the scanning settings, turn off the options: 🔍 Scan installed applications (if you use another antivirus) 📁 Scan files (unless you store suspicious files) 🔄 Automatic scanning (to avoid wasting resources)

Return to the home screen and go to the “Optimization” tab**.

Turn off Auto Clean and Accelerate if you don’t want the app to cover the background processes on its own.

You can also turn off traffic and battery monitoring if you are not using these features.

1. Go to Settings → Applications → Application Management → Security → Permissions.
2. Turn off the permits: 📊 Mobile data (if you don’t need to track traffic) 🔋 Optimizing the battery (if it interferes with the application)

Go to the application settings|Turn off automatic scanning|Turn off the autocleaning RAM|Limit background activity|Disable notifications-->

After these actions, the application “Security”** will work in a minimal mode and will not interfere with the daily use of the smartphone.

How to replace the built-in security app on Xiaomi

If you've disabled the basic features of the built-in app, but you want to maintain protection and control over the device, you can use alternative solutions. Here are some proven options:

• 🛡️ Antiviruses: Bitdefender Mobile Security is a lightweight and effective antivirus with minimal impact on performance. Kaspersky Mobile Antivirus is a reliable protection with the function of blocking phishing sites. Malwarebytes specializes in finding spyware and advertising software.
• ⚡ Optimizers: SD Maid – clears cache and unnecessary files without aggressively closing processes. Files by Google – helps free up space by removing duplicates and debris.
• 🔒 Permission Managers: App Ops (requires root rights) – gives full control over application permissions. Bouncer – temporarily grants permissions and automatically revokes them after use.

If you care about privacy, look at NetGuard, which allows you to block Internet access for individual programs without root rights, and Exodus Privacy, which analyzes applications for trackers, will also be useful.

You can use AccuBattery to monitor the battery, which provides more detailed information about the charge consumption than the built-in MIUI tools, and GlassWire, which shows which applications are consuming data in real time, is suitable for traffic control.

⚠️ Warning: Do not install multiple antiviruses at once, which can lead to conflicts and slow down your smartphone. Choose one solution and update your databases regularly.

Common Security Application Problems and How to Solve Them

Despite the useful features, the Security app often becomes a source of problems, and here are the most common ones and ways to fix them:
