Fingerprint settings for Redmi Note 8 Pro

A modern smartphone is a store of a huge amount of confidential information, so the issue of protecting personal space is especially acute.

Owners of Xiaomi Redmi Note 8 Pro often look for ways to protect their data from prying eyes using biometric methods.

The fingerprint scanner in this model is located on the back and works fast enough, but it needs to be set up correctly to work perfectly.

In this article, we will take a detailed look at the process of registering fingerprints, adding additional copies, and configuring security settings for maximum protection.

Scanner location and preparation for setting up

Before you start recording biometric data, it is important to understand the physical features of your device.

In the Redmi Note 8 Pro, the sensor is integrated into the brand logo on the back cover, making its use ergonomic.

Make sure the scanner surface and your finger are clean, as fat or moisture can significantly reduce the readout accuracy.

It is also worth checking whether a thick protective film is glued to the logo, which can interfere with the operation of the sensor.

⚠️ Note: If the scanner has a factory film with inscriptions, it must be carefully removed before setting up, otherwise the biometrics will not work.

To start, you need to unlock the device using a pin code or a pattern lock, if they are installed.

Step-by-step instructions for activating biometrics

The setup process is done through the system menu, which may vary slightly in different versions of the MIUI shell.

Open the main menu and find the Settings icon, then go to the Password and Security section.

In the list that opens, select Add a fingerprint, after which the system will request confirmation by the current unlock method.

After entering the password, the scanning process will begin, which requires attention from the user for correct operation.

During the scan, apply your finger to the sensor in different areas, without tearing it off completely after each touch.

The system will gradually fill in a pie chart showing the progress of reading skin patterns.

The subtleties of a qualitative scan of the fingerprint

Many users complain about the scanner’s poor performance, but often the problem lies in poor primary registration.

Don’t hold your finger statically in one position, as in real life we touch the phone from different angles.

Try to change the angle of your finger after each successful vibration reading by grabbing the edges of the pad.

Pay special attention to the center of the fingerprint, as this area is read most often when quickly unlocked.

💡

Register the same finger twice under different names (e.g., "Finger 1" and "Finger 1 copy") to significantly improve the speed and accuracy of unlocking.

If the scanner has stopped responding, try rubbing it with an alcohol napkin to remove fat deposits.

Re-scanning the same finger allows the system to create a more complete digital model of your biometric pattern.

Adding and managing additional fingerprints

Xiaomi’s security system allows you to store up to five different fingerprints in memory.

This is convenient if you want to unlock your phone with different fingers of one hand or add a fingerprint of a loved one.

To add a new finger, simply repeat the procedure in the settings menu by selecting a free slot.

You can rename each added fingerprint by giving it a clear name, such as "Big Left Finger".

• 👍 Registration of the thumb of the right hand for easy unlocking in the hand.
• 👍 Adding an index finger to unlock when the phone is lying on the table.
• 👍 Saving the fingerprint of the second thumb for insurance.

Removal of unnecessary fingerprints is done in the same menu by clicking on the basket icon next to the name.

This is an important step if you are selling a device or just want to clean up your biometrics database.

Setup of actions during unlocking and security

In the fingerprint menu, additional features are available that expand the possibilities of using a smartphone.

One of the useful options is the ability to unlock the device when the screen is off without having to press the power button.

You can also set up the launch of applications or create a screenshot with a long press on the scanner.

These features make interaction with the MIUI interface faster and more convenient in everyday use.

Note that some actions may conflict with the system control gestures.

If you notice strange interface behavior, try turning off additional gestures in the scanner settings.

Sensor elimination and calibration

Sometimes users are faced with a situation where the phone no longer recognizes the previously saved fingerprint.

In most cases, this is solved by simply restarting the device or re-registering the problem finger.

If the problem persists, it’s worth checking for system updates, as Xiaomi regularly releases security patches.

In rare cases, it may be necessary to reset the scanner settings through the engineering menu, but this requires caution.

⚠️ Warning: Don't try to calibrate the sensor through third-party apps from the Play Market, they are often viral or useless.

If the screen glass was replaced and the scanner stopped working, it is possible that the plume or module itself was damaged during the repair.

In such a situation, software methods will not help, and you will need to contact a service center for the diagnosis of the hardware.
