Samsung A71 fingerprint scanner

The fingerprint scanner on my A71 works for a day max before saying fingerprints not recognised. At first I thought it was my stored fingerprint which I had added to the 3 you can setup so I would delete them and then put back on. I have since discovered that instead of deleting them if I check stored prints it will 5/6 times say not recognised but then it will start to identify all 3 prints and then will work for another day or so before the same happens again. Anyone any ideas please?

Hello @douch2000 

 

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 com.samsung.android.biom 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.

Thanks for the response. I will give this a go! It is strange though that my fingerprints suddenly get recognised perfectly and without errors after I try checking them in the settings. I am wondering could there be an error some where instead.
