Owners of the popular Xiaomi Redmi Note 10S often look for the exact location of the fingerprint scanner, as the design of the device involves its integration into the side of the body. This solution has become the standard for many modern smartphones, allowing you to save a thin profile of the gadget and provide convenient access to biometric protection in any situation. Understanding the exact location of the sensor is the first step to quickly and comfortably operate your device.
Many users who are moving from models where the scanner was on the back, out of habit, can look for it there, forgetting about the side button on. The side arrangement is not only ergonomic, but also functional: unlocking occurs when you take the phone in your hand. In this article, we will discuss in detail how to adjust the biometrics, what are the nuances of the fingerprint, and what to do if the system no longer recognizes your finger.
Capacitive Touch technology used in the Redmi Note 10S requires clean sensor surfaces and the right angle of the finger to respond instantly. Scan errors or incorrect initial fingerprint recording can lead to false positives or denial of access. We will look at all aspects of this security system so that you can make the most of your smartphone.
Exact location of fingerprint scanner
The fingerprint scanner on the Xiaomi Redmi Note 10S smartphone is physically built into the power button, which is located on the right side of the body. The sensor does not protrude separately, but is part of a mechanical key, which makes it almost invisible when turned off, but convenient for tactile search with the thumb of the right hand.
It's important to understand that the scanning area takes up almost the entire area of the button, but the center part is the most sensitive. The first time you use it, it may seem like the phone is reacting slowly, but this is often due to the wrong angle of the finger. The optimal angle is when the finger pad is placed flat on the button, providing maximum contact area with the sensor.
If you wear a high-sided protective case, make sure it doesn't block access to the button or shift your finger relative to the center of the sensor. Some thick silicone cases can create a mechanical obstacle that causes your finger to slip or apply at the wrong angle, in which case it's recommended to either change the case or re-write the fingerprint to suit your accessory.

If the scanner has stopped responding, wipe the side face and finger with an alcohol napkin - fat and moisture reduce the sensitivity of the sensor.
The process of primary biometrics tuning
To activate the unlock function, go to the system settings menu. Open Settings, then select Passwords and Security and click on Unlock by fingerprint. PIN-A backup login method is used for a code or a pattern lock, and without the main password, activation of biometrics is not possible, because it is a security requirement of Android.
Once you enter the settings menu, you'll be asked to put your finger on the scanner, and the screen will show the progress bar, which fills up as you read the different parts of the papillary pattern. It's critical that you don't just press your finger statically, but you slightly change the angle of inclination, as if you were "stroking" the button, so that the sensor counts the edges and the center of the fingerprint, and if you hold your finger still, the system will only record the center part, which will lead to errors when unlocked in the future.
βοΈ Correct fingerprint recording
The MIUI system installed on the Redmi Note 10S allows you to save up to five different fingerprints, which is convenient for family use or if you want to add different fingerprints of the same hand to increase the speed of unlocking. Once the scanning process is complete, the system will suggest renaming the prints (for example, "Right Large", "Left index"), so that you do not get confused in the list.
Advanced settings and additional functions
The Redmi Note 10S fingerprint sensor is not just a way to unlock the screen, but a powerful system control tool. In the scanner settings menu, you can activate the double tap function. If the screen is off, double tapping the power button will instantly wake the device and remove the lock, bypassing the standard one-time tap to turn the screen on.
You can also use the scanner to navigate the interface and control the media, for example, swiping through photos in a gallery or switching tracks in a music player is done by swiping the power button up or down, which is especially useful when the second hand is busy, and allows you to manage content without touching the screen.
Hidden capabilities of the scanner
Another useful feature is the ability to use fingerprint for authorization in applications and payment systems. Google Pay (now Google Wallet) and banking applications support biometric confirmation of transactions3 actions. This greatly speeds up the process of paying in stores and logging into secure applications, eliminating the need to enter complex passwords every time.
Decoding of indicators and signals
Xiaomi Redmi Note 10S provides the user with feedback on the scannerβs state through vibration and color indication (if supported by the theme of the design) or text messages. Understanding these signals helps to quickly diagnose the problem. For example, a short vibration usually means a successful readout, while a series of vibrations or no reaction indicates an error.
The table below shows the main states of the indicator and the actions to be taken:
| Status of the indicator | Sound/tactical signal | User action |
|---|---|---|
| Blinks blue/green | Single vibration | Successful unlocking or reading |
| Burning red. | Double vibration. | Recognition error, try the other finger |
| It's not burning. | No reaction. | Check the battery charge or restart the device |
| Slow blinking | Long vibration. | The process of recording a new print is underway. |
It is worth noting that in power saving mode, the brightness of the backlight of the button can decrease, which sometimes creates the illusion of a malfunction. If you notice that the scanner has become less responsive after turning on the energy saving mode, try turning it off or increasing the screen timeout in the display settings.

The red error indicator is most often due to sensor contamination or a sharp change in ambient temperature.
Typical problems and methods of their solution
Despite the reliability of the technology, users may find themselves in a situation where the scanner no longer recognizes previously stored fingerprints. One of the most common causes is contamination of the button surface with moisture, sweat or fat. In this case, simply wipe the side face with a soft cloth.
Sometimes the failure happens at the software level after you update your MIUI system, and in those cases, resetting your biometrics helps, delete all the saved fingerprints in the Passwords and Security menu, and write them back down. When you re-write, try to use the fingers and angles you're used to, but add a little more variation in your movements.
If software isn't working, it might be mechanical damage to the button plume or the sensor itself, which often happens after the phone falls or gets moisture inside, and then the button may or may not stick with a tactile response (click), and repairing the service center is the only solution for hardware malfunctions.
β οΈ Warning: If the fingerprint scanner stopped working after the phone hit the water, do not try to dry it with a hair dryer or put it on the battery. High temperatures can melt the glue that holds the button and damage the internal components.
Expert advice for stable work
To ensure maximum speed and reliability of the fingerprint scanner on the Redmi Note 10S The experts recommend following a few simple rules: First, always have a backup way to unlock.If the main finger is damaged (cut, burned) or dirty, you should be able to enter quickly. PIN-code.
Second, if you're left-handed, adjust your sensitivity, or just get used to the fact that your left thumb might be on the button at a different angle than your right, and it's helpful to write your left thumbprint separately, specifically at an angle that's specific to yours.
- π§Ό Regularly wipe the side of the smartphone, as there accumulates the most dirt from the hands.
- π± Do not record the fingerprint immediately after showering or gymnasium when the skin of your fingers is shriveled from moisture.
- π Update your fingerprint recording every few months if you notice a slowdown in your reaction rate.
- π‘οΈ Use high-quality protective films that do not have thickenings in the area of the power button.
Compliance with these guidelines will allow you to forget about the problems with access to the device. Biometrics is a convenient tool that, when used correctly, saves seconds every day, adding up to hours per year of use of the smartphone.
β οΈ Warning: Do not attempt to disassemble the power button yourself to clean the sensor, which will result in loss of warranty and a high risk of damage to the plume, which is very fragile.
