How to add a fingerprint on Xiaomi Redmi: instructions with photos and tips for error elimination

The fingerprint scanner on Xiaomi Redmi smartphones is not only a convenient way to unlock, but also an additional level of protection of personal data. However, many users face problems when first setting up: the system does not recognize a finger, there are errors like โ€œfailed to add a fingerprintโ€ or the scanner works every time. In this article, we will analyze the step-by-step algorithm for adding a fingerprint, talk about the nuances for different Redmi models (from Redmi Note 10 to Redmi 13), and give tips for solving typical problems.

It is important to understand that the process may vary slightly depending on the version of MIUI (for example, MIUI 14 simplified the interface settings, and HyperOS added new security options). We have taken into account all the current updates in 2026, so the instruction is suitable even for fresh firmware. If your Redmi does not recognize the fingerprint after several attempts, do not rush to bring it to the service: in 90% of cases, the problem is solved software.

Before you start, check two key points: 1 Make sure there is no protective film or glass on the screen with an oleophobic coating - it can block the infrared scanner. 2) Your fingers should be clean and dry (sweat, cream or dirt distort reading). If you have recently washed your hands, wait 1-2 minutes until the skin drys naturally.

1. Prepare the smartphone before adding a fingerprint

Before you add a fingerprint, you need to do a few preparatory steps, which will help you avoid errors like "Figurative scanner is not responding" or "Failure to save the template." Let's start by checking the hardware and software conditions:

  • ๐Ÿ”‹ The battery must be at least 20% charged, and at low charge, the system can interrupt the adjustment process.
  • ๐Ÿ“ฑ Update MIUI: Go to Settings. โ†’ The phone. โ†’ Update the system and install the latest patches. In older versions of the firmware, the scanner may not work properly.
  • ๐Ÿ”’ Whether identified PIN-It's not possible to add a print without it, because that's a security requirement of Xiaomi.
  • ๐Ÿงด Finger condition: Avoid adding prints with cuts, calluses, or severe dry skin.

Pay special attention to the protective glass. On some Redmi models (for example, Redmi Note 11 Pro+), the scanner is built into the display, and thick glass can block its operation. If you recently glued a new protection, try to temporarily remove it. Also check if the scanner has scratches or chips: physical damage often causes failures.

โš ๏ธ Note: If you use a magnetically fastened case (for example, for wireless charging), remove it before setting it up.

Check the battery charge (minimum 20%)

2. Step-by-step instructions: how to add a fingerprint

Now, letโ€™s move directly to the addition of a fingerprint. The instructions are universal for most Xiaomi Redmi models, but we will note the nuances for devices with a scanner in the power button (for example, Redmi 9A) and a subscreen scanner (Redmi Note 12 Pro+).

Open the settings and follow the following steps:

  1. Go to the Passwords and Security section (some versions of MIUI call it Lock and Protect).
  2. Select โ€œAdd Fingerprintโ€ (or โ€œFingerprintโ€ โ†’ โ€œAdd Fingerprintโ€).
  3. Enter the current one. PIN-code or pattern lock for confirmation.
  4. Follow the hints on the screen: ๐Ÿ‘† Put your finger on the scanner (for the power button, press and hold it). ๐Ÿ”„ Raise and lower your finger until the scale is 100%. ๐Ÿ” The system will ask to scan the edges of the finger โ€“ this increases the accuracy of recognition.

Name a print.

For models with a subscreen scanner (Redmi Note 12/13, Redmi K60) it is important: Don't press too hard - the sensor is triggered by a light touch. High pressure can lead to the error "Too weak signal".

If the scanner doesnโ€™t respond, try wetting your finger (not wet!) or wipe the screen with a lilac-free wipe.

If a fingerprint is not added the first time, try using the other finger, and some users have noted that thumbs are worse read because of the wear and tear of the skin pattern.

3. Typical errors and how to fix them

Even with the right setup, Xiaomi Redmi users can encounter errors, and we have collected the most common problems and ways to solve them:

Mistake.Possible causeDecision
I couldn't get a print.Dirty scanner or finger, outdated firmwareWipe the sensor with alcohol, update the MIUI, reboot the phone
The fingerprint scanner is not responding.Hardware failure or conflict with the coverRemove the case, check the sensor for damage, reset the scanner settings.
The fingerprint is recognized once.Too quick touch or too weak contactAdd the fingerprint again, holding the finger for 1-2 seconds
There is no option to add a fingerprint.Disabled sensor in the developer settingsTurn on Settings โ†’ About Phone โ†’ MIUI version (5 times), then For Developers โ†’ Debugging over USB โ†’ Turn off fingerprint check

If none of these methods worked, try resetting the scanner settings: Settings โ†’ Applications โ†’ Application Management โ†’ Three dots (menu) โ†’ Reset settings.

Then add the print again. In extreme cases, you may need to completely reset your phone (but remember to back up!).

โš ๏ธ Note: Some Redmi models (e.g. Redmi) 8A) The fingerprint scanner is not physically available, even though the option may appear in the menu.

4. How to manage saved prints

Once you add a print, you can edit the name, delete it, or add new ones.

  1. Open Settings โ†’ Passwords and Security โ†’ Fingerprints.
  2. Enter. PIN-proof-code.
  3. Click on the desired print in the list: โœ๏ธ Rename โ€“ change the name (for example, from โ€œFinger 1โ€ to โ€œBig leftยป). ๐Ÿ—‘๏ธ Remove the fingerprint (confirmation required) PIN-code).

Add a print.

On a single Xiaomi Redmi device, you can save up to 5 fingerprints (depending on the model), which is convenient if you use the phone more than one person or you want to add different fingerprints (for example, index and large) for easy unlocking.

If you notice that the scanner has become worse at recognizing the fingerprint over time, this may be due to: wear of the skin pattern (for example, in builders or athletes), changes in skin moisture (winter skin is drier, in summer - more sweaty), damage to the sensor (if the phone fell).

What if the scanner stopped working after the update?
After major MIUI updates (e.g., from MIUI 13 to MIUI 14), the scanner may temporarily shut down. Try: 1. Reboot the phone in Safe Mode (hold the power button โ†’ โ€œReboot Safe Modeโ€). 2. Clear the system cache: Settings โ†’ Memory โ†’ Clear cache. 3. If the problem persists, roll back to the previous firmware version via Fastboot (instructions are available on the 4PDA forum).

5. Additional security settings

The Xiaomi Redmi fingerprint can be used not only to unlock the screen, but also to:

  • ๐Ÿ” Authorization in applications (for example, in banking or instant messengers).
  • ๐Ÿ’ณ Payment confirmations (via Google Pay or Mi Pay).
  • ๐Ÿ“ Access to hidden folders (in the Files or Gallery appยป).
  • ๐Ÿ”‘ Entrance to the safe zone MIUI (if she's tuned in).

To enable these options: Settings โ†’ Passwords and security โ†’ Fingerprints โ†’ App settings.

Here you will see a list of compatible programs where you can activate unlock by fingerprint.

Please note that some banking applications (e.g. SberBank Online or Tinkoff) may require additional setup. If the print does not work in a particular application: 1) Make sure that the application settings allow biometrics. 2) Reinstall the application (sometimes helps). 3 Check if the access is blocked by antivirus or MIUI Optimization (in the developer settings).

A fingerprint is convenient, but donโ€™t forget to back up your unlocking options (PIN or pattern lock).In the event of a hardware scanner failure, you may lose access to your phone!

6. Comparison of scanners on different Redmi models

The fingerprint scanning technology on Xiaomi Redmi has evolved over the years, and letโ€™s look at the key differences between the two models:

ModelType of scannerRecognition speedFeatures
Redmi 9/9A/9CIn the power button~0.5 sec.Trusted, but requires a push.
Redmi Note 10/11Sideways (in the button)~0.3 sec.Faster than the 9th series.
Redmi Note 12 Pro+Subscreen optical~0.2 sec.It works by light touch, but is sensitive to dirt.
Redmi K50/K60Ultrasonic subscreen~0.1 sec.The fastest, working with wet fingers

If youโ€™re planning to buy a new Redmi and youโ€™re looking for a fingerprint scanner, look for ultrasonic sensors like the Redmi K60, which are not only faster, but also more reliable in high humidity or dirty hands, but are more expensive to repair: replacing the sensor can cost up to 50% of the price of the phone.

For budget models (Redmi 10A, Redmi 9A), the power button scanner is the best solution, it is less whimsical and less likely to break, and its main disadvantage is the need to press a button, which is not always convenient with one hand.

7.Alternative ways to unlock if the scanner breaks

If your Xiaomi Redmi fingerprint scanner has stopped working permanently (for example, after a fall or moisture), donโ€™t despair.

  • ๐Ÿ”ข PIN-A password or code is the most reliable option, but less convenient.
  • ๐Ÿ–ผ๏ธ pattern lock - faster PIN-code, but less secure.
  • ๐Ÿ‘ค Facial recognition (if you have a front camera) is included in Settings โ†’ Passwords and security โ†’ Facial recognition.
  • ๐Ÿ“ Smart Lock (unlock by location or Bluetooth device) Configured in Settings โ†’ Google โ†’ Smart Lock.

If you decide to repair the scanner, consider: The replacement cost varies from 1,500 to 5,000 rubles depending on the model. The warranty on the phone will burn if you contact an informal service. Self-repair is almost impossible - soldering equipment and experience are required.

Before repairing, check if the software reset helps: Settings โ†’ About phone โ†’ Resetting โ†’ Reset all settings.

This will return the scanner to factory settings, but will not delete personal data.
