Owners of Xiaomi, Redmi and Poco smartphones often encounter a system component called Miuibiometric, which is responsible for the work of biometric protection: face recognition (Face ID) and fingerprint scanning. However, users are looking for ways to remove or disable this component when faced with errors, constant notifications or the desire to increase the autonomy of the device.
In most cases, complete deletion of a system file is not possible without deep interference with the firmware structure, which can lead to loss of warranty and unstable security system operation.However, there are effective methods of deactivation of functions and data reset that solve problems with intrusive notifications or sensor freezes.
Before we take drastic measures, it is important to understand the nature of the problems. Often, the "how to remove" request is due to a module malfunction, not the actual need to remove it. Competent setting of access parameters and cleaning the cache can eliminate 90% of the malfunctions without the risk of turning the smartphone into a "brick".
What is Miuibiometric and what is it responsible for?
The Miuibiometric system process is the core of biometric security in the MIUI shell and the new HyperOS. It processes sensor data and compares it to reference samples stored in a secure memory area, and it is this component that makes the decision to unlock the screen or confirm payments.
If you notice that a process is consuming a lot of power or is constantly hanging in the background, it may indicate a conflict of software versions or damage to system files. In normal state, it only activates when you access the sensors. Constant activity indicates a failure in the sensor survey cycle.
Users often confuse this process with a virus. However, Miuibiometric is a legitimate component of the Android operating system with Xiaomi add-ons, and it cannot be removed by standard methods, since it has system application rights.
💡
Before any manipulation of system processes, be sure to back up important data to a cloud service or computer.
Reasons for needing to disconnect or delete
The main reason users want to get rid of Miuibiometric is because of errors in the fingerprint scanner. The smartphone may stop responding to touch or, conversely, unlock spontaneously, in which cases, the application's data reset often returns functionality.
Another common scenario is increased battery consumption, where if the sensor is stuck in an active state, it starts to continuously poll the surface of the screen or the front camera, which leads to a rapid discharge of the battery even in standby mode.
- 🔒 Continuous requests for re-registration of fingerprint.
- 🔋 Abnormally high charge consumption in the background.
- 📱 Errors when using banking applications and Google Pay.
- 🚫 Inability to add a new biometric template.
It is also worth noting cases when, after updating the firmware, the old face pattern or fingerprint ceases to read correctly. The system requires a full re-registration, but the old conflicting file interferes with this process.
How to disable biometrics through system settings
The safest way to remove Miuibiometric's impact on your device is to disable biometric unlocking through the standard menu, which won't delete the file, but deactivates its functions. Go to Settings, then select Password and Security.
In the menu that opens, find the Fingerprint and Face Unlock items, you need to log in to each section and delete all the saved templates, and once the last template is removed, the system will automatically stop using biometrics for authorization.
⚠️ After disabling all biometric methods, the only way to unlock will be the pattern lock, PIN-Make sure you remember them so you don't lose access to the device. If your goal is to just stop using Face. ID, But leave a fingerprint, delete the data only in the appropriate section, Xiaomi system allows you to flexibly manage these parameters without the need to completely abandon the technology. ☑️ Disable biometrics Open Settings→Go to Password and Security→Delete fingerprints.→Delete the faces→Check the work Completed: 0 / 1 Clean up the data and cache of the Miuibiometric application When simple deactivation does not help, you need to reset the application itself, which will return the Miuibiometric component to the post-fabrication state. → Annexes → All applications. In the list of applications, find Miuibiometric (sometimes displayed as "Biometry" or have a fingerprint icon). Click on it, select Memory and then tap Clear → All data. The system will warn about the risks, but to correct errors this is necessary. After cleaning, your fingerprints and face will be deleted. The next time you turn on the biometrics, the system will require you to re-register your biometric data. This often solves problems with incorrect reading. Action Resetting the template Remodeling The method will not interfere with the phone's logging on, or the remote installation of the system will only require a defect from the fad module. What to do if Miuibiometric is not found in the list?If you don't see the application in the general list, turn on the system process display. To do this, click three dots in the corner of the application list screen and select "Show system." ADB For advanced users who want to completely remove the component from active use, there is a method through ADB (Android Debug Bridge. This is a way of connecting to your computer and installing drivers. It hides the package from the system, effectively disabling it. First you need to activate the developer mode. Go to Settings. → About the phone and 7 times quickly click on the build number (MIUI Version) Then in the additional section → For developers, turn on debugging by USB. Connect your smartphone to your PC and type the following command in the command line: adb shell pm disable-user --user 0 com.miui.biometric This command will force the process to stop for the current user. If you need to return functionality, use the command adb shell pm enable com.miui.biometric. Be careful: misuse ADB It may disrupt other system services. ⚠️ Attention: Use of teams ADB To disable system packages can cause the smartphone to work in an unstable way, only if you understand the consequences. Solving common errors and failures A common problem is the message "failed to add a fingerprint" or an endless scanning cycle. In such cases, a consistent reset of security services helps. Try turning off your phone, pressing the volume and turn on button, then releasing only the on button, continuing to keep the volume up until the Fastboot logo appears, and immediately rebooting to normal mode. If errors continue, check for system updates. Xiaomi developers regularly release patches that fix bugs in the Miuibiometric module. → About the phone and check the version of the software. 🔄 Complete reset (backup required). 🧹 Clean Downloads section of temporary installer files. 🛡️ Check the device with antivirus for malware. In rare cases, the problem is hardware in nature. If after resetting the data and flashing the scanner continues to work incorrectly, the sensor plume or the module itself may be damaged. In such a situation, software methods to remove the error will not help. 💡If the software methods don't work, the problem may be the sensor hardware, which requires you to go to the service center. Can you completely delete Miuibiometric without root rights? Complete physical deletion of the system file without superuser rights (Root) is not possible. ADB-The commands allow the packet to be deactivated for the user, which is functionally equivalent to deleting, but retains the ability to recover. Is it safe to disable biometrics for banking applications? Yes, it is secure. Bank applications will simply switch to using a password or PIN-But some quick-pay features may become less convenient. Why did the firmware updates lose prints? Major Android or other updates. MIUI Security system can forcibly reset biometric data to protect information. This is a routine behavior that requires re-registration.
