Owners of Xiaomi, Redmi and POCO smartphones often face intrusive advertising or incomprehensible processes in the system, one of which is MiuiBiometric.This system component is responsible for the work of biometric protection, including facial unlock and fingerprint, but sometimes it begins to behave incorrectly. Users notice its activity in the battery logs or see associated notifications on the lock screen, which raises questions about security and privacy.
Removing or disabling this process requires caution, as it is part of the MIUI and HyperOS shell. Mistakes can result in the inoperability of the fingerprint scanner or Face ID. In this article, we will discuss safe methods for deactivating unnecessary functions, cleaning the cache and completely removing advertising components associated with biometrics, without losing the warranty and stability of the system.
Before we start taking drastic measures, we need to understand the nature of the problem. MiuiBiometric is often confused with a virus, although it is a legitimate but sometimes redundant component of the system. Disabling MiuiBiometric is completely disables face unlock and fingerprint on the device. So if your goal is just to remove ads or reduce battery consumption, it is better to use methods to limit background activity, not completely delete.
What is MiuiBiometric and why is it necessary?
MiuiBiometric is a system service integrated into the shell. MIUI, It's the one that manages the collection and processing of biometric data, and it's the one that enables facial unlocking and fingerprint scanner. Without this component, the standard authentication methods offered by the manufacturer will cease to function and you will have to use only a pattern lock, PIN-code.
Normally, this process consumes minimal resources and is activated only when you try to unlock the device. However, users often complain that the service starts consuming battery power in the background or displays notifications similar to ads, this can be due to errors in a particular version of the firmware or conflict with installed applications.
β οΈ Note: Complete removal of the system package through ADB Root rights can cause a cyclical reboot of a device (bootloop) if other security services depend on it.
It's important to distinguish between system process and potentially malware masquerading as it. If you see high activity of MiuiBiometric in battery statistics without using a phone, that's a reason to do a diagnostic. In some cases, MSA (MIUI System Ads) advertising modules may use similar names to mask their activities.
Preparation of the device before making changes
Before you start to disable system services or clean the data, you need to perform a number of preparatory actions, which will help to avoid loss of important data and will allow you to return all settings to the original state in the event of an error. First, make sure that your Xiaomi battery is at least as high as yours. 50-60%.
Back up your sensitive data. While we'll be working with system settings, there's always a risk of accidental reset or error. Copy contacts, photos and documents to the Mi Cloud or your computer. It's also recommended that you turn off the Internet while you're doing the manipulations so that the system doesn't automatically try to update remote components.
βοΈ Checklist of preparation for system modification
If you plan to use advanced methods through your computer, make sure that your PC has ADB drivers installed. For ordinary users who do not want to connect the phone to your computer, standard settings will suffice within the Settings menu. In any case, calmness and attentiveness are the main tools when working with system files.
Disconnection method through application settings
The safest and easiest way to limit MiuiBiometric activity is to use a standard application management menu, which does not require root rights or special knowledge, but stops the process and cleans up accumulated data, which often solves the problem of intrusive notifications or high power consumption.
To start, go to your smartphone's Settings menu. Find the Apps section and select All Apps. You'll want to find a process called MiuiBiometric or Biometric. If it's not on the list, click on the three dots in the top right corner and select Show System Processes.
- π± Click on the MiuiBiometric app you found to log in to its menu.
- π Select the Stop or Close option to end your current service session.
- π§Ή Press Clear Clear. β Clean everything to delete temporary files and cache.
- π« If you have a Disable button, press it. If it's gray, it means that the system prohibits a complete shutdown without superuser rights.
After you do this, restart the device. Note that after you restart, the system can automatically start the process again, as it is necessary for security functions to work. However, cleaning the cache often eliminates errors that cause increased energy consumption.

If the βDisableβ button is inactive, try to turn off the Internet before entering the app menu β sometimes this temporarily removes the blocking of system restrictions.
Using ADB to remove system component
For users who want to get rid of MiuiBiometric completely and understand the risks, there is a USB debugging (ADB) method that allows you to uninstall system applications without obtaining root rights, but requires a computer and a USB cable.
First, activate Developer Mode. Go to Settings β About Phone and press 7 times on MIUI Version (or OS Version). Then, in the Additional β For Developers menu, turn on USB Debugging and USB Debugging (Secure Settings).
adb shell pm uninstall -k --user 0 com.miui.biometricThis command will remove the biometrics package for the current user, and once it's done, the face unlock function and the fingerprint will stop working, and if you want to get it back, you'll need to reset your phone completely to the factory settings.
| ADB Team Team | Action. | Risk |
|---|---|---|
| adb shell pm list packages | Shows a list of all packages | Safe. |
| adb shell pm uninstall ... | Remove the selected package | High (loss of function) |
| adb shell pm enable ... | Turns on the deactivated packet | Medium. |
| adb reboot | Reboots the device | Safe. |
Using ADB gives you complete control over the system, but requires technical literacy. A mistake in the packet name can lead to the removal of critical components, such as the phone book or system interface. Always double-check the packet name before running the delete command.
Disconnecting MSA and Mi Daemon Advertising Services
Often users are looking for a way to remove MiuiBiometric when they are actually annoyed by ads that masquerade as system notifications. Advertising on Xiaomi is more often the responsibility of MSA (MIUI System Ads) and Mi Daemon, disabling these services is safe and does not affect biometrics.
To limit advertising, go to Settings β Passwords & Security β Access to Personal Data. Find the msa service in the list and turn off the switch. The system will warn you several times about the consequences (10 seconds of waiting), but you need to insist on your own and choose to turn off.
- π Find it in the list of applications MIUI Daemon and also restrict its access to data.
- π In the Getting Recommendations section, disable all sliders to reduce the number of intrusive offers.
- π Check Security settings and disable the βReceive recommendationsβ option in the Memory Cleanup section.
β οΈ Attention: Service MSA It can automatically turn on again in 24 hours, periodically check this setting or use third-party firewalls to block her access to the Internet.
After disabling the ad modules, the load on the processor will decrease and the lock screen will become cleaner, which is a more effective way to combat discomfort than removing the biometric services that still provide basic protection for the device.
Why is MSA turning on again?
Impact on safety and alternatives
Complete removal of MiuiBiometric compromises the security of your personal data.Without this component, you will not be able to use fast payments via NFC (Mi Pay, Google Pay), authorization in banking applications through print and quick unlock of the device.
If your goal was to improve performance, removing system services will provide minimal gains on modern devices; it is much more effective to turn off animations in the developer menu or remove heavy applications that you do not use. Modern Snapdragon and Dimensity processors easily cope with the background processes of biometrics.
Alternatively, third-party launchers or lock-in apps can be used to remove control, but this can create conflicts in the system, and the best solution is to properly adjust existing parameters and regularly clean the cache.

Removing MiuiBiometric deprives the smartphone of the functions of quick unlock and secure payment, so it is recommended only to limit the background activity of the service.
