Finger print recognition

[nilocp]

Forgive if this has been covered before, but I have just bought a new S10+. I have scanned in my fingerprint, but when I try to use it I get the message 'Fingerprint doesnt  match!'

I only use the same finger as on my old phone, why isnt it recognised?

Have you fitted a screen protector since registering your fingerprint? Some screen protectors and films can cause the reader to not be effective.
Try this:
- register the fingerprint again (as FP 2, 3 etc) but with your finger placed slightly different.
- Under 'Display' in settings turn on 'increase touch sensitivity'.

When I first got the phone I scanned my finger print with some difficulty. Then I put a screen protector on. Fingerprint not recognised. So I deleted it and scanned again. Eventually got 100% . Message now is fingerprint not recognised!

I have now increased touch sensivity. Guess what it will not even scan my print at all FP2. Not even 1%. Messages 'Make sure your finger covers the entire sensor' or 'Press a little harder'!!

For info the screen protector is 9H super hardness. The same as my old HTC which worked fine!

With touch sensitivity increased then delete your previous FP's and try re-adding them. I had to do that when changed my protector from an edge adhesive 9H one to one that used full UV adhesive

Ooh! Deleted FP1, re-scanned, quite quickly, and it seems to be working now.

For info the protector is full UV adhesive.

Spoke too soon!!!  Sometimes it works, most times it doesn't!

Had my hopes up that it had solved it 😔
