Bought a Note 20 Ultra 5G and just got a Tab S7+.

The finger print recognition does not seem to work most of the time.

I had a Note 9 before and the finger print recognition worked like a dream. No issues what so ever.

My two new very expensive Samsung items which the under screen finger print scanners do not work 90% of the time. 

What am I doing wrong? Or do the not work as planned

I used to have some issues with my phone and then did this.


Perhaps take a look @PeterInYork 


A couple of tips I picked up when setting up the finger prints are.

When setting up take x3 scans with each thumb and then rotate the phone around when taking further prints of each thumb so your phone can read both thumbs from the same finger print scan. Scan your prints as you would normally hold the phone.

Also using two fingers when setting up one fingerprint works pretty well.

Go into Settings . Biometrics and Security.  Biometrics Preferences . Turn Off Screen Transition Effect.

Then go into Settings and search for Optomise Battery Usage. Tap in Optimise  Battey Usage  tap to show All and scroll down to and toggle Off

For me this improved the fps on my Note.

I also have dry skin on my fingers and so find it sometimes beneficial to moisten my fingertip by breathing on it before unlocking the phone.


Hope the above helps in some way.
