If your Samsung device has an ultrasonic fingerprint sensor (Galaxy S series), don't follow this procedure. For more information, check out the ++[document|2746327502|Samsung Self-Repair document]++. | | | You'll need the Samsung fingerprint sensor calibration toolkit in order to complete this procedure. | | | Note: the device used is a Samsung Galaxy Tab S7+, but the procedure is identical across all Samsung devices with an in-screen optical fingerprint sensor. |
