Xiaomi’s Personal Security App: Hidden Features, Settings, and Disconnection Risks

If you’ve ever looked into the list of installed apps on a Xiaomi smartphone, you’ve probably noticed a strange system software called “Personal Safety” (Personal Safety or Security in English firmware). It doesn't get deleted, it doesn't have a desktop label, but it does appear regularly on the active process list. What kind of program is it? Why is it so important for you to use it? MIUI? And can it be safely turned off if it interferes with the operation of the device?

In fact, “Personal Security” is not one application, but a whole range of services responsible for protecting user data, controlling permissions and even emergency functions (for example, for example, for the user’s personal security services, SOS-Unlike the antivirus Mi Security, which scans files for viruses, this software works at a deeper level - it is integrated into the Android kernel and is closely related to the corporate shell. MIUI. Without it, many smartphone features (from locking the screen to encrypting files) will simply stop working.

In this article, we will discuss in detail:

• 🔍 What exactly does the Personal Security app do and what processes it controls.
• ⚙️ Where to find its settings and how they affect the smartphone (including hidden options).
• ⚠️ How dangerous is it to disconnect this service – from loss of functionality to security vulnerabilities.
• 🛠️ How to minimize its impact on performance if it eats away at battery or RAM.

1.What is “Personal Security” on Xiaomi: Technical Details

The application "Personal Security" (com.miui.guardprovider in the system) is a service module MIUI, which performs several critical tasks:

• 🔐 Managing permissions for other applications (access to camera, microphone, geolocation, etc.).
• 🛡️ System Integrity Control – Checks to see if system files have been changed (e.g. after root access).
• 📱 Screen lock and biometrics – responsible for the work of fingerprint, facial recognition and PIN-code.
• 🚨 Emergency functions — SOS-Calls, sending location to contacts in a critical situation.
• 🔄 Data encryption – involved in file protection and backups.

In fact, it is the “brain” of security. MIUI, Without which the shell loses most of its defenses, for example, if you turn off this service, it will stop working:

• 🔒 Password blocking of applications (the “Application Protection” function in Settings) → Passwords and security).
• 📍 Tracking your device through Find Device (similar to Apple’s Find iPhone).
• 🔑 Automatically cleansing data after 10 failed password attempts.

It is important to understand that “personal security” is not the same as:

• 🛡️ Mi Security (antivirus and optimizer).

⚠️ Note: On some models (e.g. Xiaomi) 12T Or Redmi Note 11) this app can be displayed as "Security" or "Security." To make sure that's what it is, check it out. ID package in the application settings - it must begin with com.miui.guardprovider.

2. Where to find the settings of "Personal security" and what is hidden there

Unlike most system applications, Personal Security doesn't have a separate section in the Settings menu, and its features are spread across different tabs, and you need to know where to look to manage them.

There are hidden settings that don't show up in the standard menu, so you can open them.

1. Go to Settings → The phone.
2. 5 times press the version MIUI (A notification will appear saying, “You have become a developer»).
3. Back to the settings → Additional → for developers.
4. Find the Debugging Point by USB and turn it on.
5. Connect your phone to your PC and type in the command: adb shell dumpsys activity service com.miui.guardprovider This will display a list of all active security modules.

One of the most useful hidden tools is the Security Log, which captures all suspicious activities, such as root access attempts, changes to system files, locks the screen, and opens it:

1. Enter the dialer code ##4636##.
2. Go to the Usage statistics tab.
3. Find com.miui.guardprovider and click on it.
4. The Security Log button will appear at the bottom.

⚠️ Note: Not all Xiaomi models support access to Security Log. on some devices (e.g., security logs, POCO F4) This section may be blocked by the manufacturer.

3.Why "Personal Security" is loading the CPU and battery (and what to do about it)

Many users complain that the com.miui.guardprovider process is constantly hanging in active tasks, consumes up to 10-15% of battery power and loads the processor.

• 🔄 Constant permission checks – the service scans application activity in real time.
• 📡 Background synchronization with Xiaomi servers (for example, for the Find Device function).
• 🔍 Vulnerability scanner – Looks for suspicious changes to the system (especially after updates).
• 📱 Conflict with other antiviruses (e.g. Avast or Kaspersky).

If you notice that Personal Security is eating up too many resources, try the following steps:

1. Disable unnecessary functions: 🔍 Turn off the security scanner in Settings → Passwords and security → Security scanner. 📍 Turn off device tracking if you don’t use Find Device. 🔄 Remove the checkmark from Automatic Vulnerability Check.

Limit background activity:

adb shell cmd appops set com.miui.guardprovider RUN_ANY_IN_BACKGROUND ignore

This command will prevent the application from working in the background (required) ADB).

Cash it down:

1. Go to Settings → Applications → Application Management.
2. Find your personal security (or security).
3. Press Warehouse. → Clear the cache.

If nothing helps, you can try to roll back the service update (but it’s risky!):

1. Download the old version APK (For example, with APKMirror).
2. Set it through ADB: adb install -r -d com.miui.guardprovider.apk
3. Reset the device.

If you want to minimize the impact of this service, there are safer alternatives:

The safest way to reduce the load is to turn off individual functions, as described in the previous section. If you are willing to take risks, here is a manual for partially disabling through the system. ADB:

1. Connect your phone to your PC and enable USB Debugging.
2. Enter the command to turn off background activity: adb shell pm disable-user --user 0 com.miui.guardprovider/.securitycenter.SecurityCenterActivity
3. Reset the device.

After that, the basic security features will remain operational, but the service will no longer be permanently hanging in the process.

💡

Complete removal of Personal Security makes your smartphone vulnerable to attacks and deprives most of the security features MIUI. Even if you think the app is getting in the way, first try disabling its individual modules.

5. Personal Security Connection with Other Xiaomi Services

This service is closely integrated not only with MIUI, And with other Xiaomi products, such as:

• 🌐 Mi Account – without “Personal Security” it is impossible to link your device to your account or use cloud backups.

For example, if you reset your phone to factory settings without disabling your Mi Account, the system will require you to enter your account login and password (FRP Lock is implemented through com.miui.guardprovider. If you remove this application, unlocking the phone after reset will be almost impossible without an official unlocker from Xiaomi.

Another important thing is security updates, because every month Xiaomi releases patches to fix vulnerabilities, and these patches are installed through the Personal Security module, and if it's disabled, your smartphone will be left without critical patches, making it an easy target for viruses or hacker attacks.

6. Alternatives to “Personal Security”: Can it be replaced by third-party solutions?

If you don't like standard Xiaomi protection, can you use third-party antivirus or permission managers instead? Theoretically, yes, but with reservations:

The main problem with third-party solutions is that they can't replace system functions.

• 🔒 Biometrics (fingerprint, facial recognition) only works through built-in Xiaomi modules.
• 📱 Screen locking cannot be reassigned to third-party software – this is a limitation of Android.
• 🔄 Security updates are only installed via com.miui.guardprovider.

If you want to use alternatives, here is a minimally safe scheme:

1. Turn off only the security scanner in the settings (but leave the rest of the features).
2. Install Bouncer to manage permissions (it temporarily blocks application access).
3. Use Bitdefender for antivirus protection (but turn off its background activity).
4. Set up Google Find My Device as a backup way to find your phone.

⚠️ Note: On devices with Global ROM (Disabling the built-in security mechanisms may result in the blocking of the Mi Account due to suspicious activity, especially for models with HyperOS (new shell instead of new ones). MIUI).

7. Frequent "Personal Safety" Errors and Problems (and How to Fix Them)

Sometimes security services fail to work properly, such as constantly making errors, blocking legitimate applications, or refusing to run at all.

If none of the solutions helps, you can try resetting the security settings to the factory:

1. Go to Settings. → Passwords and security.
2. Click on the three dots in the top right corner and select Reset Settings.
3. Confirm the action (you will need to enter) PIN-code).

If the problem persists, the last option is to reflash the phone through the Mi Flash Tool, but before you do, you must:

• 📱 Make a backup copy of the data.
• 🔒 Make sure you know the username and password from Mi Account (confirmation may be required after firmware is installed).
• 🔄 Download the official firmware for your model (not custom!).

💡

If the security settings have stopped working SOS-If you call or lock the screen, it means that the service has been damaged at the system level, and then only flashing the screen will help.
