How to Calibrate an Optical Fingerprint Sensor

简介

Follow this guide to calibrate the in-screen optical fingerprint sensor in your Samsung phone or tablet. You should perform the calibration whenever you replace the screen, to ensure that the fingerprint sensor is accurate and secure.

This calibration procedure currently only works for the Tab S7+'s optical fingerprint sensor. This guide will update as Samsung adds more compatibility. For more information, check out the Samsung Self-Repair document.

You'll need the Samsung fingerprint sensor calibration toolkit in order to complete this procedure.

I have a Galaxy A70. "Fingerprint sensor Calibration needed" when I try to turn on Biometric. *# 0 *# says the sensor is alright (everything pass) But calibration = 1

HOW do I calibrate the sensor? The local samsung service center is trash

Hi there.

Unfortunately, as stated in the introduction, the only device supported right now is the Tab S7+ . Samsung plans to include more devices with time.
