Dedicated fingerprint unlocks only the secure folder. The ultrasonic fingerprint sensor you are talking about unlocks the whole phone. I think the Dedicated fingerprint is missing in s20 which is too bad. Samsung must add it back. Please update the software.
yes in my s20 ultra also have same issue.....please samsung add dedicated fingerprint for secure folder in s20 ultra series.
otherwise i stop to use samsung mobiles.
I to miss the dedicated finger for the secure folder. Most people would never guess to use a different finger for a different portion of the phone.
My old S9+ i could use my right thumb for my phone, the left thumb for secure folder. This was great while the phone was off I could just use what ever thumb to open the different option instead of having it unlock automatically
