Z Fold users can't use Fingerprint scanner to log on when the phone is unfolded or tablet mode. Developers explains that the phone is in desktop mode which is why it asks for credentials. However, that is not the case. The phone is still in mobile mode until the user chooses to go to desktop mode. Mobile mode is the primary setting which is why I am writing this review. How about you work with a Samsung Fold before replying because you obviously never worked with one.
