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

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