How to turn on a fingerprint on Xiaomi Mi 11 Lite: a step-by-step guide

Xiaomi Mi 11 Lite smartphone is equipped with a built-in screen fingerprint scanner, which provides not only high security, but also ease of use. Modern biometric technology allows you to instantly unlock the device with one touch, eliminating the need to enter complex passwords in uncomfortable situations. However, to properly work this feature, you need to properly configure the recognition system, following certain algorithms of actions in the menu of the operating system.

The process of activating biometric protection in the MIUI or HyperOS shell is quite simple, but requires careful attention during the scanning phase, since the speed and accuracy of subsequent unlocking depends on the quality of the data. In this article, we will discuss all the stages of configuration in detail, consider additional security parameters and answer frequently asked questions related to the operation of the sensor on the Mi 11 Lite model.

The scanner’s proper setup not only unlocks your phone, but also confirms payments in Google Pay (or its analogues), logs in to banking apps, and protects hidden folders. Ignoring this feature leaves your device vulnerable to unauthorized access, so we strongly advise taking a few minutes to properly configure your security system.

Preparing the device for security settings

Before you start scanning your finger, you need to make sure that the device is ready to work with biometric data. First of all, your Xiaomi Mi 11 Lite must have a strong digital password, PIN or pattern lock. This is a mandatory requirement of Android security: biometrics is only a convenient addition, not a replacement for the main method of unlocking.

If you have not previously installed a lock screen, the system will automatically redirect you to the appropriate menu when trying to turn on the fingerprint scanner. It is recommended to choose a PIN code of 6 or more digits, as it is easier to enter in emergency situations than a complex graphical pattern. It is also worth checking the cleanliness of the screen, since greasy spots or a low-quality protective film can significantly reduce the sensitivity of the optical scanner.

⚠️ Warning: Make sure the battery is at least 15-20% before setting up to avoid accidentally shutting down the device at a critical time of system security file configuration.

It is also important to consider the condition of your finger: if the skin is too dry or, conversely, wet, the scanner may not work properly, in such cases, it is recommended to slightly moisten the finger or, conversely, wipe it with a dry cloth before starting the scanning procedure for the best result.

Step-by-step instructions for activating the fingerprint scanner

To start the setup process, you'll need to go to the main settings menu of your smartphone. Find the gear icon on your desktop or notification curtain and click on it. In the settings list that opens, you'll need to find the password and security section. In current versions of MIUI firmware, it's often called Passwords and Security.

Inside this section, you're interested in "Unlocking by fingerprint." When you click on it, the system will prompt you to enter your current screen unlock password to confirm administrator rights. Once you've successfully authorized, the biometrics management menu will open, where you click "Add fingerprint." The screen will go out, and animation will appear, instructing you to apply your finger to the specified area.

The scanning process requires sequential action. You have to put your finger on the scanner area (the bottom of the screen) repeatedly, changing the angle slightly each time. The system will read different areas of the finger pad, creating a full digital cast. Don't rush to tear your finger off until the vibration confirms that the site has been read successfully.

  • πŸ‘‰ Place your finger in the center of the scanner area without moving it too much up or down.
  • πŸ‘‰ Change the angle of your finger after each vibration to cover the edges of the pad.
  • πŸ‘‰ Try not to move the smartphone in your hand, hold it steadily on weight or on the table.
  • πŸ‘‰ If the progress bar has stopped, click β€œAdd more” or β€œContinue” to scan the missed sections.

Advanced settings and additional prints

After successfully creating the first fingerprint, the system will suggest adding a second finger or adjusting additional settings. On the Xiaomi Mi 11 Lite, you can save up to 5 different fingerprints. This is especially convenient if you want to unlock the phone with your right or left thumb, or if you share the device with a trusted person (for example, a spouse or child).

There are important options available in the fingerprint management menu that are worth considering, such as unlocking in your pocket (or similar depending on the version of MIUI) that allows the sensor to work even when the screen is off, which speeds up access, and you can remove old or incorrect prints to free up space and improve recognition accuracy.

Why do you need a few prints?
Adding the same finger under different names (e.g., "Finger 1" and "Finger 1 copy") often increases the unlock speed, as it is easier for the system to find a match in the database.

Remember to update your fingerprint database regularly. If you notice that your phone is less responsive to touch, remove the old cast and create a new one. Over time, the skin microrelief may change, or you may have initially scanned your finger in the wrong position you would normally unlock the device.

Using a fingerprint for payments and applications

One of the main advantages of biometrics on Xiaomi Mi 11 Lite is the ability to use a fingerprint instead of a password in applications, this applies to banking customers such as Sberbank Online, Tinkoff, Alpha Bank, as well as payment systems Google Wallet and app stores Play Market.

To activate this feature, it is usually enough to enter the settings of a particular application and find the Security or Fingerprint Login section. Once you enable this option, the application will request biometric confirmation at each start or before making a transaction, which greatly increases the level of protection for your finances.

Importantly, after the device is rebooted, opening the first banking apps will still require entering a master password or PIN, a standard security measure of the Android operating system that cannot be software-bypassed.

Solution: If the scanner is not working properly

Despite the high technology of Xiaomi Mi 11 Lite, users can face situations where the fingerprint is not read, most often the problem lies in the contamination of the screen or the use of the wrong protective film.

If you recently changed the security glass and then the scanner stopped responding, try removing it and checking the sensor on a clean screen, and it is also worth reconfiguring the fingerprint, paying special attention to the edges of the finger, which are often ignored in the initial scan.

⚠️ Attention: Using cheap matte or thick hydrrogel films can completely block the operation of the optical scanner under the screen".

In some cases, cleaning the security cache helps. Go to Settings β†’ Applications β†’ All applications, search the list for Security or Security, click Clear Data and Clear Cache. After that, you will need to add fingerprints again, but this often solves software failures.

Influence of protective glasses and accessories

Owners of the Xiaomi Mi 11 Lite often wonder about the compatibility of protective accessories with biometrics. Since the scanner is built directly into the display, any layer between the finger and the sensor affects the reading quality. Thick hardened glass can reduce sensitivity, requiring stronger pressing.

It is recommended to choose thin protective glass with oleophobic coating, which are specially designed for smartphones with scanners under the screen. If you use a case with high sides, make sure that it does not overlap the bottom of the screen, where the scanning area is located.

πŸ’‘

When buying a protective glass for Xiaomi Mi 11 Lite, pay attention to the presence of a scanner cutout or special labeling about compatibility with optical sensors.

It is also worth remembering that in bright sunlight, the optical scanner may work less stable due to the external illumination of the matrix, in such situations it is easier to use an alternative method of unlocking or simply shield the top of the screen with your hand from direct sunlight.

FAQ: Frequently Asked Questions

Is it safe to keep a fingerprint on your phone?
Fingerprint data is not sent to Xiaomi or Google servers, but is encrypted and stored in a special secure module (TEE) inside your Xiaomi Mi 11 Lite processor, which is not accessible by conventional applications.
Can I unlock my phone with a wet finger?
The optical scanners used in the Mi 11 Lite don't work well with water. The water distorts the light reflected from the finger pad, so the system won't be able to recognize the fingerprint, so use a PIN or wipe your finger dry.
Will the imprint be reset when the system is updated?
With a conventional air-to-air firmware update (OTA), the biometrics settings are saved, but if you completely flash through your computer or reset to factory settings, all the prints will be deleted and you will need to reconfigure them.
Why does the phone ask for a password instead of a fingerprint after the reboot?
This is a standard Android security requirement. After each full device reboot, the first unlock must be done exclusively by the primary method (PIN, password or pattern lock) to confirm that the device is owned by its owner.

πŸ’‘

Regular reconfiguration of the print and the use of high-quality protective glasses is the key to stable and fast biometrics on your Xiaomi Mi 11 Lite.
