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.
