Clear the fingerprints and re-register them. Make sure your hands are dry when doing it. If you use a screen protector, turn on touch sensitivity in display settings.

Also something to think about to improve the Fingerprint sensor is to scan 4 fingers. I do 2 of my left thumb and 2 of my right thumb.

Sometimes it could just be what's on your hands, like products, hygiene stuff like that, I say that because sometimes I would have the same problem, but what I do i would just wash my hands and in the security print is working like a charm.

After you set it up, make sure your hands are bone dry. It won't register. Lotion those hands lol. My phone unlocks 100%.

That's a good question Fit bit is a different company that makes fitness trackers. I'm trying to figure out what they were referring to.

If your hands are TOO dry, the fingerprint sensor may have problems reading your prints. I get this problem every winter - the low humidity makes my hands dry out and my fingerprints get smooth and hard to read. Put some moisturizing lotion on your hands and make sure it's soaked in well (so your hands aren't sticky) before trying to use the fingerprint sensor.

The S25 lets you have four fingerprints? My phone only allows 3.

I thought it allowed 4 but I can't check at the moment

Make sure your finger isn't to wet, or to dry...

I alwys have trouble with the fingerprint scan. Too dry or too wet is not good. Maybe I just dont have deep prints 🤷‍♀️
