How to put a fingerprint on Xiaomi: step-by-step setting

Owning a modern Xiaomi smartphone means not only communication and entertainment, but also reliable protection of personal data. One of the most convenient and quickest ways to ensure the security of your device is the use of biometric data, in particular, fingerprint. This feature allows you to instantly unlock the screen, confirm payments and hide confidential applications from prying eyes.

The process of setting up a fingerprint scanner in the shell of MIUI or the new HyperOS is as simple as possible and takes only a few minutes. However, users often face nuances, such as low sensitivity of the sensor or the inability to add a second finger. In this article, we will discuss in detail how to properly configure the biometrics to work faultlessly in all conditions.

It’s worth noting that the location of the scanner may vary depending on the model of your device. On older or budget models, the sensor is often located on the back, next to the camera, whereas in flagship models it is built directly into the display. Regardless of the type of sensor, the software setting remains almost identical for all current versions of the operating system.

Preparation of the device for setting up biometrics

Before you start a direct scan, you need to make sure that the system is ready to work with your biometrics. First of all, check whether your device has a reliable digital code, pattern lock or password. Android security requires a backup unlock method in case the scanner can not read the fingerprint, for example, after a device reboot or if the finger is wet.

It is also recommended to wipe the scanner area with a soft cloth. Fat marks, dust or moisture can significantly reduce read accuracy and increase response time. If you have Xiaomi with a scanner underscreen, the cleanliness of the display at the bottom of it plays a critical role. A dirty screen can lead to false denials of access, which will cause irritation in daily use.

⚠️ Warning: Do not try to stick protective glass or film immediately after purchase without checking the scanner.Some thick or poor-quality protective coatings may block the sensor signal, especially if it is embedded in the screen.

Make sure your software is updated to the latest available version. Xiaomi engineers regularly release patches that improve biometrics algorithms. Go to Settings → About the phone and check for updates. This will help avoid bugs that could have been fixed in more recent firmware assemblies.

Step-by-step instructions for adding a fingerprint

The main process of registering your finger is in the security settings menu. To get started, open the main settings menu and find the Passwords and Security section. In some versions of the shell, this item may be called simply Security or located inside the Additional menu. The interface may slightly differ visually, but the logic remains the same for the entire ecosystem of the brand.

In the menu that opens, select Unlock with your fingerprint. The system will prompt you to enter a previously installed digital code or pattern lock to confirm the rights of the administrator-rector. After successful authorization, click Add fingerprint. An animation will appear on the screen, instructing you to apply your finger to the center.

Put your finger on the scanner, slightly changing the angle and position. The learning algorithm should count not only the center of the pad, but also the edges of the pad. Don't press your finger too hard, with a light enough touch. 10-15 The time period during which the progress indicator will be filled.

Once the scan is successful, the system will suggest giving a name to a new fingerprint, such as the "Right Large" or "Left Index." This is especially useful if you plan to add multiple fingerprints or family fingerprints.

Setup application lock and hidden profile

One of the most useful features in Xiaomi smartphones is the ability to put separate protection on specific applications. You can hide correspondence in instant messengers, photos in the gallery or access to banking applications using the same fingerprint. → Annexes → Application protection.

Activate the protection function and set a password if you are doing it for the first time. Then, in the list of installed programs, select those that you want to restrict access to. Once the protection is turned on, when you try to open the selected application, the system will request confirmation through the fingerprint scanner, which creates an additional level of data privacy, even if the phone is already unlocked.

In addition, MIUI has a "Second Space" feature, which is a full-fledged second workspace with its applications and files, hidden from the eyes of outsiders, and you can also log in to this profile with a special, pre-configured fingerprint, just put another finger on the scanner on the lock screen, and the phone will open the hidden interface.

⚠️ Warning: If you forget the password from a hidden profile or apps, it will be extremely difficult to restore access without a data reset.Make sure your main fingerprint is stable before relying on it to access critical data.

Using biometrics to log in to apps makes it much faster, so you don't have to type long passwords or draw complex keys every time, just one tap, and Mi Bank, Mi Wallet, or third-party banking apps will give you access to finance.

Use of fingerprint for payments and authorization

Modern Xiaomi smartphones support NFC and secure payment technology, and Google Pay (or its peers like Mir Pay) requires at least one fingerprint to be added to the system to work properly, a security requirement for payment systems that ensures that the device owner makes the transaction.

To activate the payment with a fingerprint, add a bank card to the appropriate application. When you first pay or add a new card, the system will ask you to confirm the action with biometrics. In the future, you will need to simply unlock the phone and bring it to the terminal for payment in stores.

In addition to payment, a fingerprint is used to log in to the Google Play store when buying apps or subscriptions, which prevents children from buying randomly or spending unauthorized items, and many third-party apps, such as password managers or notes, allow you to use a system scanner to quickly log in.

💡

Use different fingers for different purposes: for example, unlock your phone with your thumb and confirm payments with your index finger so you always know what access you are authorizing.

It's important to understand that fingerprint data is not transmitted to the Internet or stored on company servers, but is stored in a secure part of the memory of the processor, which is isolated from the main operating system, which makes it almost impossible to steal biometric data even when a smartphone is hacked.

Advanced settings and sensitivity management

In advanced scanner settings, you can often find options that affect speed and accuracy. For example, in some models, the feature Accelerated Unlock is available, activating it causes the scanner to respond to lighter touches, but can increase battery consumption, since the sensor is in a state of high alert.

You also need to look at the vibrations of a successful scan, and the tactile response helps you know that the phone recognizes the finger, even if the screen hasn't caught fire yet, and you can set the strength and duration of the vibration in the Sound and Vibration section. → Vibration on touch.

For users who often wear gloves or with wet hands, it can be helpful to train the scanner. Remove the old print and add it again, but in the scanning process intentionally apply your finger at sharper angles and with less effort, which will expand the sensor database and improve recognition in difficult conditions.

If you use a case with thick sides, make sure that it does not overlap the scanner area. Owners of models with a subscreen scanner are advised to use special protective glasses marked "Compatible with fingerprint sensor." Regular thick glass can completely block the operation of the sensor.

The solution: why the scanner is not working

Despite the high reliability of the technology, users can face problems, and one of the common causes is contamination of the sensor or finger, if the phone no longer recognizes your fingerprint, wipe the screen and hands, and the problem can be hidden in a software security failure.

The table below shows the main problems and ways to solve them:

If the software methods don't work, there may be a hardware malfunction, which could be a plume that's moving away from the board, or damage to the sensor itself when it falls, and then you need to be diagnosed at an authorized service center.

⚠️ Warning: Do not attempt to disassemble your smartphone yourself to clean the scanner plume.This will result in loss of warranty and may damage other components such as the battery or display.

Sometimes it helps to reset your network settings or completely reset to factory settings, but this is an extreme measure.Be sure to back up all important data to the Mi Cloud cloud or your computer before doing this.

Features of work in different models Xiaomi

Xiaomi, Redmi and Poco are extremely diverse. In the budget models of the Redmi Note series, the scanner is often combined with a power button on the side of the phone. It is an ergonomic solution that allows you to unlock the phone with a natural hand movement when you grab the device.

The flagship Mi and Xiaomi models come with ultrasonic or optical subscreen scanners, which take up less space inside the body and make the design more seamless, but their speed may depend on the brightness of the screen and the type of protective coating.

In some ultra-budget models, the fingerprint scanner may not be physically present. In such cases, the system suggests using face unlock. Although it is less secure than a print, this may be enough for basic protection against accidental access. Always check the specifications of a particular model before buying if the presence of biometrics is critical for you.

Understanding your model will help you set up your device as efficiently as possible, so don’t be afraid to experiment with sensitivity settings and add multiple fingerprint options for the same finger to improve reliability.
