Where is the fingerprint of the Xiaomi Redmi Note 10 Pro

Xiaomi’s modern smartphones are equipped with advanced biometric protection systems, and the Redmi Note 10 Pro is no exception. First-timers often look for a physical scanner on the back, accustomed to the classic location of sensors in older models.

Understanding the exact location of the sensor is critical to quickly and conveniently unlocking the gadget. An optical scanner built into the display requires a specific push other than mechanical. If you look for a convex button or a recess on the body, your search will be in vain, since the entire surface of the front panel is touch-sensitive.

In this article, we will discuss in detail where the readout zone is active, how to properly configure the biometrics and what to do if the system stops recognizing your finger. Proper setting will not only ensure the security of your data, but also increase the speed of access to the device in everyday use.

The design and location of the sensor in the Redmi Note 10 Pro

Unlike the low-end versions of the Redmi series, where the scanner is often placed on the side face or back cover, the Note 10 Pro uses in-display technology. This means that the sensor is hidden under layers of AMOLED matrix and glass. Visually determine its exact boundaries is impossible until you turn on the unlock function or start the setup process.

The physical active area is located at the bottom of the screen, about the center of the horizontal axis, just above the bottom edge of the display, but below the center, where content is usually displayed, and this position is chosen ergonomically, allowing you to unlock the phone with the thumb of one hand without intercepting the device.

It's worth noting that the reading area doesn't occupy the entire bottom of the screen, it's a compact area, and hitting the center of the screen greatly speeds up the system's response. The optical sensor in the Redmi Note 10 Pro is illuminated by a characteristic greenish or white glow at the time of touch, which serves as visual confirmation of activation.

Using a subscreen scanner allows you to maintain the integrity of the design of the rear panel, which in this model is made of glass and often has interesting textures. The absence of cutouts under the camera or the scanner at the rear also improves the tactile sensation of the device and prevents dirt from accumulating around the mechanical elements.

How to properly activate and configure the scanner

To get started with biometrics, you have to go to the appropriate settings menu, which is standard for the MIUI shell: open Settings, then select Passwords and Security, and that's where all the access control tools for your device are.

In the menu that opens, you need to find the item Unlock by fingerprint. PIN-A code or pattern lock, if installed, is a mandatory security measure that confirms that the device owner is setting up the device.

Then you add a fingerprint, put your finger on the bottom of the screen and press it slightly, and the screen will vibrate every time you read a piece of your finger, and it's not just about putting your finger statically, it's about shifting your finger a little bit, changing the angle of tilt, so that the sensor can remember the pattern from all angles.

Once the scan is complete, the system will suggest creating a backup password. Don't ignore this step, as it will be needed if the sensor temporarily stops responding or after the device has restarted.

Features of the optical scanner

The technology used in the Redmi Note 10 Pro is optically readable, and underneath the screen is a miniature camera that takes a picture of a finger when it's brightly lit, which makes it different from capacitive scanners that respond to the skin's electrical current.

One of the features is the requirement to clean the screen surface: Fat spots, dust or water droplets in the scanning area can distort the light flux, which will lead to recognition error. Regularly rubbing the bottom of the display with a soft fabric significantly improves reliability.

⚠️ Attention: Using poor-quality protective glasses with a thick adhesive layer or matte coating can make scanning impossible. the optic sensor is sensitive to the transparency of the material above it.

Also, it is worth considering that optical scanners may react more slowly in very bright ambient light, such as direct sunlight, and in such conditions, the brightness of the sensor's backlight may not be sufficient for contrasting a papillary pattern.

To improve response speed, the “Increase Scan Area” option or similar option is often available in settings, which expands the sensitivity zone by sacrificing minimal battery power.

Comparison with other biometrics methods in Xiaomi

Xiaomi has different types of sensors in its arsenal, and understanding their differences will help you better appreciate the capabilities of the Note 10 Pro. The table below compares the subscreen optical scanner with other common options.

The underscreen solution in the Redmi Note 10 Pro is better than the side and rear scanners in terms of aesthetics and moisture protection, since there are fewer holes in the case. However, in terms of speed, mechanical buttons can still have a slight advantage in cold weather or when working with gloves (although the optical scanner does not work in gloves anyway).

Compared to the face unlocking that is also available in this smartphone, fingerprinting is a more reliable method. Face scanning in this model is done by a conventional front-facing camera and can be fooled by the photo, whereas the fingerprint is unique and requires physical presence.

Typical problems and ways to solve them

Even with the right finger positioning, users can experience a situation where the smartphone no longer recognizes the fingerprint, most often due to software failure or contamination, the first thing to do is to thoroughly wipe the bottom of the screen and the finger itself.

If cleaning didn’t work, try removing the stored fingerprint from your memory and writing it back again. When re-write, it’s recommended to add the same finger twice under different names (e.g., “Finger L1” and “Finger L2”), which will increase the database and increase the likelihood of successful recognition.

⚠️ Note: If the scanner has stopped responding fully (not even vibration or backlighting), the problem may be in the hardware of the display plume, especially if the device has recently been hit or dropped.

Also worth checking for system updates. Xiaomi engineers regularly release patches that improve biometrics algorithms. Go to Settings → About Phone and check the MIUI version.

💡

To improve scan accuracy in winter when the skin is dry, slightly touch the surface of your forehead or nose before unlocking, which will moisturize the skin and improve contact with the optical sensor.

The effect of protective accessories on the scanner

Choosing a protective glass for the Redmi Note 10 Pro requires care. Cheap glasses with poor optical transparency or thick oleophobic film can block the light needed for the sensor to work, resulting in a slowdown in the unlock speed or the function stops working altogether.

Accessories manufacturers often label their products as “print scanner compatible.” It is recommended to choose glass no more than 0.3 mm thick. The thicker options (0.5 mm and higher) create too much distance between the finger and the sensor, which blurs the image.

If you use a hydrrogelium film, there are usually fewer problems, because it is thinner than glass, but over time, the film can appear scuffled in the scanning area, which also requires the replacement of the accessory.

The quality and thickness of the protective glass directly affect the speed and accuracy of the underscreen fingerprint scanner.
