Introduction

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.

    • Place the white box over the outline near the bottom of the screen.

    • Cover the outline with the side on the box that matches the pattern.

    • Make sure the white box completely covers the outline. Deviations could result in a "Fail" result or an inaccurate calibration.

    Where do i get the white box?

    Hi there.

    Currently, the only way to get the boxes is by purchasing the Galaxy Tab S7+ Screen kit. Samsung intends to sell them separately at some point. This guide is only for the Galaxy Tab S7+ at the moment.
