Modern smartphones like the Xiaomi Redmi Note 7 offer users a variety of biometric security techniques, with fingerprint scanning taking the lead in popularity. However, there are times when this feature is no longer convenient or begins to cause technical problems that require immediate intervention.
The reasons for this can range from the banal desire to improve security to the physical damage to the sensor itself located on the back. If the scanner is not working properly, it can block access to the device or create false positives, preventing normal use of the MIUI. In this guide, we will discuss in detail all available ways to deactivate this feature.
It's important to understand that the process of removing your fingerprint doesn't just temporarily shut down the scanner, it completely erases the encrypted data about your biometrics from the protected memory area, which ensures that even with a deep analysis of the system by third parties, it will be impossible to restore your fingerprints. Let's look at how to properly perform this procedure on your Redmi Note 7.
Main reasons for disabling biometric protection
Users rarely decide to give up the convenient unlock feature for no good reason, most often due to technical failures in the hardware or software of the MIUI shell. The sensor can begin to react with a delay, which is annoying with frequent use of the smartphone during the day.
In some cases, the problem lies in the physical condition of the scanner surface or the user's fingers, wet skin, the presence of a protective film on the sensor, or contamination can lead to permanent recognition errors. PIN-code or pattern lock too often, which negates the benefits of biometrics.
- 🔒 Increased security requirements for transferring a device to third parties for repair or sale.
- 🛠️ Physical failure of the scanner module causing chaotic system behavior.
- 📉 The desire to save battery power, as the background work of the sensor consumes energy.
- 🧼 Hygienic considerations or temporary damage to the skin of the fingers, impeding recognition.
⚠️ Warning: If you are planning to sell your Xiaomi Redmi Note 7, be sure to delete all fingerprints before resetting your settings to factory settings so that new owners do not get access to your data through biometrics.
Also worth mentioning are the software conflicts that can occur after an operating system update: sometimes new firmware versions contain bugs that affect the scanner drivers, and in such situations, temporarily disabling the feature helps diagnose the source of the problem and determine whether the software update is to blame.
Standard procedure for removing fingerprints through settings
The easiest and safest way to disable the scanner is to use the built-in settings menu of the Android operating system with the MIUI shell. This method does not require root rights or a connection to the computer and is available to any user. Before starting the procedure, make sure that the smartphone screen is unlocked and you have access to the main menu.
To enter the relevant section, you need to open the Settings app and find the password and security item. The interface may vary slightly depending on the version of MIUI installed on your Redmi Note 7, but the logic remains the same for all Xiaomi devices. Follow the step-by-step instructions below.
☑️ Pre-deletion check
Go to the Settings section → Passwords and confidentiality → Fingerprints: The system will request proof of your identity by requiring you to enter your current password, PIN-The code or pattern lock that is used to unlock the screen is a critical step in protecting the biometrics from being removed by unauthorized persons.
Once you have successfully logged in, you'll see a list of all the saved fingerprints, usually numbered (Finger 1, Finger 2, etc.) or have names if you've given them before. Click on the desired fingerprint to open additional control options, and select "Delete." Repeat the procedure for all the saved data if you want to disable the feature completely.
| Action. | The way is on the menu | The result |
|---|---|---|
| Opening the settings | Settings → Passwords and privacy | Access to the security section |
| Managing fingerprints | Fingerprints. | List of stored data |
| Deletion of data | Choosing a finger → Delete | Erasure of biometrics |
| Total reset | Removal of all fingerprints | Function disabled |
💡
If you delete a fingerprint to sell your phone, it is also recommended to perform a full Wipe Data reset via the Recovery menu to ensure that all personal information is cleared.
Use of alternative methods of unlocking
Once you have decided to disable the fingerprint scanner on the Xiaomi Redmi Note 7, the system will automatically switch to the standard method of protection. PIN-A code, pattern lock, or complex password that you set up when you first set up your device. Make sure you remember this combination, as it will be the only way to access it.
Smartphone owners often forget about other biometric or smart unlocking features that can be a great replacement for a finger scanner, such as Face ID, which is less secure than a print, but is much more convenient to use with gloves or wet hands.
- 📱 pattern lock: a familiar and fast way that requires memorization of the figure.
- 🔢 PIN-Code: Classic digital protection, most compatible with all services.
- 🔑 Password: The most reliable, but time-consuming security option.
- 👤 Face unlock: a convenient alternative that works through the front camera.
It is worth noting that some applications, such as bank clients or corporate encryption, may require at least one active biometric security method or a complex password. If you completely remove the fingerprint, make sure you have a strong digital code installed, otherwise some programs may be limited in functionality.
⚠️ Warning: When you enable face unlock, remember that this technology on the Redmi Note 7 uses the same technology. 2D-The camera can be less protected from the owner’s photo than the fingerprint scanner.
Switching between unlocking methods occurs instantly after the last fingerprint is deleted, and the system will immediately request password confirmation the next time the screen is activated, which is normal behavior, confirming that biometric data has been successfully deleted and access is only protected by the user's knowledge.
Solving problems with the freeze of the scanner function
Sometimes users want to turn off the scanner not because they don’t need it, but because it stopped responding or isn’t working properly. In such cases, the standard settings menu may not be available or the removal feature may be blocked by a system error. This is a common problem for the Xiaomi Redmi Note 7, especially after falls or moisture.
If the settings menu freezes when you try to log into the fingerprint section, try forcibly rebooting the device. Press the power button for 10-15 seconds until the smartphone vibrates and the Mi logo appears. Often this helps to reset temporary driver errors and restore access to biometric management.
What to do if the scanner is buggy?
In more complex cases, when the sensor is physically functional but software-locked, safe mode can help, and booting in this mode disables all third-party applications that may conflict with system functions, and if the scanner is working normally in safe mode, then the problem lies in one of the applications you install.
To enter Safe Mode on MIUI, you need to press the Off button, and when the Off icon appears on the screen, press it and hold it until you suggest that you go to Safe Mode. After checking, try to remove the fingerprint again through the standard menu. If this does not help, you may need a deeper intervention in the system.
Resetting settings as a radical method of disabling
When software failures become critical and prevent security functions from being managed through the regular menu, the only option is a full Hard Reset, which completely clears the device’s internal memory, including all stored fingerprints, accounts and user data.
Before you decide to take this step, you need to back up all the important data, since it will be impossible to restore it after a reset without a backup. Reset can be done through the settings menu if the phone is turned on, or through Recovery mode if the device is locked or does not load normally.
To reset via the menu, go to Settings → About Phone → Settings Reset → Erase all data. The system will warn you that all files will be deleted. Confirm the action by entering the password from the Mi Account if it is activated. Once rebooted, the Redmi Note 7 will be as new, without any fingerprints.
| Resetting method | Data security | Difficulty | Implementation time |
|---|---|---|---|
| Removal of the print | Data saved | Low. | 1 minute |
| Reset via menu | Data deleted | Medium | 10-15 minutes. |
| Recovery Mode | Data deleted | Tall. | 15-20 minutes. |
| Mi Flash (PC) | Data deleted | Very high. | 30+ minute |
Recovery mode is required if the phone is not turned on or locked. To do this, press the power and volume buttons at the same time. In the menu that appears, using the volume buttons, select Wipe Data and confirm the choice with the power button, this will ensure that all traces of biometrics are removed.
Impact of disabling on application operation and security
Disabling the fingerprint scanner can affect the operation of some applications that are tied to biometric authorization. Banking applications such as Sberbank, Tinkoff or Google Pay (now Google Wallet) often use the fingerprint to quickly confirm payments and log in to your personal account.
After the fingerprint is removed, these applications will automatically switch to a password request or PIN-This may seem less convenient, but it increases the level of control, because access requires code knowledge, not just a finger, and in the settings of the applications themselves, you can re-activate biometrics if you decide to add a fingerprint later.
It is important to note that the Mi Unlock feature on Xiaomi devices is also closely related to account and security practices. If you plan to unlock a bootloader in the future to install custom firmware, having a customized biometrics is not necessary, but a stable security system is important for linking the device to the account.
⚠️ After a full reset (Hard Reset) on modern versions of Android and MIUI protection FRP (Factory Reset Protection! you will definitely need a password from your Google account and Mi Account that were synced before the reset.
Also worth mentioning is the effect on autonomy. Although the fingerprint scanner consumes a small amount of power in standby mode, constantly questioning the sensor when a malfunction can lead to micro-slowdowns and unnecessary charge consumption. Disabling the problem module sometimes helps to extend the life of the Redmi Note 7 from a single charge.
💡
Disabling a fingerprint scanner is the irreversible deletion of biometric data that requires knowledge of an alternate password to access the device and applications.
