The Xiaomi Redmi 10S fingerprint scanner is one of the key biometric protections that many users are actively using to quickly unlock the screen. However, not everyone knows exactly where the sensor is located, especially if it is a budget model with a custom design. Unlike flagship devices, where the scanner is often integrated into the screen or power button, in the Redmi 10S, its placement can cause questions.
This article will not only help you find the fingerprint sensor on your smartphone, but also to set it up correctly, and to deal with typical problems, from incorrect reading to complete lack of response. We will look at the physical location of the scanner, the features of its operation depending on the firmware version, and also give practical tips for optimizing use. If you just bought a Redmi 10S or faced difficulties in unlocking, here you will find the answers to all the questions.
Physical location of fingerprint scanner on Xiaomi Redmi 10S
In the Xiaomi Redmi 10S, the fingerprint scanner is located on the back of the device, at the top of the body, just below the main camera. This is a classic solution for Xiaomi budget models, where the sensor is designed as a small oval depression with a metal ring on the edge. It is important to note that the scanner here is not aligned with buttons (unlike some Redmi Note models) and is not built into the display.
To accurately identify the sensor, pay attention to the following visual signs:
- 📍 Position: approximately in the center of the top third of the back cover, between the camera and the Redmi logo.
- 🔍 Appearance: oval shape, slightly recessed in the case, with a shiny metal rim.
- 🖐️ Tactile sensations: When touched, the finger should feel a slight resistance - this is normal for capacitive scanners.
If you can't find the sensor, try swiping your finger down the back of the panel from top to bottom, and the scanner will be visible to the touch as a small indentation, and you can also target the protective film, which is often the manufacturer puts the sensor contour on it.
How to activate the fingerprint scanner in settings
Even if you find the sensor physically, you have to set it up correctly in the system, and by default, the scanner is disabled, and you have to take a few steps to activate it.
- Go to Settings → Passwords and Security → Fingerprint.
- Enter. PIN-code or pattern lock (if not installed, the system will prompt you to create it).
- Click Add fingerprint and follow the instructions on the screen, putting your finger on the scanner from different angles.
- After a successful scan, select what actions the fingerprint will be used for: unlocking the screen, confirming purchases in Mi Pay or accessing secure folders.
Important: The system will require at least one spare unlock method (PIN or pattern lock) to be added in case the scanner stops working, and it is also recommended to register multiple fingers (for example, indexes of both hands) for convenience.
☑️ Preparation for scanner setup
Why fingerprint scanners may not work: common problems
If the sensor doesn't respond to touch or it gives an error, the reasons can be both software and hardware.
| Problem. | Possible cause | Decision |
|---|---|---|
| The scanner doesn't recognize the fingerprint. | Dirt on the sensor or finger, skin damage | Wash the scanner with an alcohol wipe, use the other finger |
| Sensor does not respond to touch | System failure, outdated firmware | Reboot your phone, update your MIUI |
| Error "Fine scanner not responding" | Hardware malfunction or damage to the plume | Contact the service center. |
| Slow reading | Too many registered prints | Remove unnecessary prints in the settings |
Special attention should be paid to the cleanliness of the sensor: even a slight contamination can lead to malfunctions. To clean, use a soft fabric soaked in isopropyl alcohol (do not use abrasive materials!). If the problem persists after all the manipulations, you may need to reset or diagnose at the service center.
⚠️ Warning: Do not try to disassemble the phone yourself to clean the sensor - this can lead to loss of warranty.If you suspect a hardware breakdown, contact only authorized specialists.
Redmi 10S scanner compared to other Xiaomi models
Xiaomi’s lineup uses different types of fingerprint scanners, and the Redmi 10S is no exception.
- 📱 Redmi Note 10 Pro: the scanner is built into the power button (side panel), which is more convenient for simultaneous on and unlocking.
- 📱 Mi 11: Under-screen ultrasonic scanner, faster and more reliable, but more moisture sensitive.
- 📱 Poco X3 Pro: a scanner on the back, similar to Redmi 10S, But with an improved recognition algorithm.
- 📱 Redmi 9A: No scanner (budget model without biometrics).
The Redmi 10S is in the middle of a better scanner than the Redmi 9A, but less convenient than the Note 10 Pro. The main advantage is the low price while maintaining functionality. However, if you care about unlock speed, consider models with a side or underscreen sensor.

Optimization of the scanner: tips and tricks
To make the fingerprint scanner on Redmi 10S work as efficiently as possible, follow these guidelines:
- Register your finger from different angles. When you add a fingerprint, not only apply your finger directly, but also under a slight tilt, which will improve the accuracy of recognition.
- Use "smart unlock." In the security settings, activate the option to unlock when lifting (if available) so that the phone unlocks when removed from your pocket.
- Update the firmware. Newer versions of MIUI often improve fingerprint recognition algorithms.
- Avoid wet conditions. Capacitive scanners don't work well with wet fingers - wipe your hands before unlocking.
Important: If you use a safety glass or film on the back, make sure it doesn't close the sensor, and some high-sided covers can also block access to the scanner.
💡
To speed up unlocking, register the fingerprint of the finger you most often hold your phone with. For example, if you are right-handed and hold your smartphone with your left hand, add the fingerprint of your right index finger.
