The system will run a self-test and attempt to clear and recalibrate the software cache for the sensor.
The Ultimate Guide to the Samsung Fingerprint Calibration Tool: Fixing Biometric Errors
I need to start with a crucial warning:
Samsung links the security chip (Knox Knox platform) to the specific biometric hardware module. When a new display is introduced, the optical or ultrasonic sensor detects a change in light refraction or acoustic impedance. Without running the official calibration tool to update the security registry, the phone disables the sensor to prevent biometric spoofing and security breaches. Frequently Asked Questions Can I calibrate my Samsung fingerprint sensor without a PC?
These generally do not require a physical calibration tool, as they use sound waves. However, they may still need a software-based recalibration, which is usually handled through a Samsung Authorized Service Center or specialized service software.

Explain the difference in calibration between (S-series) and optical (A-series) sensors Share public link
In the landscape of modern mobile technology, biometric authentication has largely supplanted the Personal Identification Number (PIN) as the primary method of device access. Samsung Electronics, a market leader in the Android ecosystem, has pioneered the mass adoption of both optical and ultrasonic in-display fingerprint sensors. However, the efficacy of these sensors is contingent upon precise hardware configuration.
Ensure you are on the latest One UI update .
It aligns the optical or ultrasonic sensor with the display, allowing the device to "learn" the new glass layers (crucial after a screen replacement) or reset its calibration data if the sensor has become uncalibrated, resulting in frequent errors. The system will run a self-test and attempt
You will generally need to use a calibration tool in the following scenarios:
If you are using the official calibration firmware/software, the process generally looks like this:
Plug your phone into your computer and ensure all USB drivers are updated.
Tap to measure the current electrical and optical baselines. Without running the official calibration tool to update

Found in flagship models (e.g., Galaxy S24, S23, S22 series). They use sound waves to map the 3D ridges of your print.
The is the official solution to resolve these biometric sensor misalignments. This comprehensive guide explains what the tool is, when you need it, and how to use it to restore your phone's security features. What is the Samsung Fingerprint Calibration Tool?
Once the tool displays a "Success" prompt, restart your phone.
