Fingerprint sensor issues

[Fiz7863]

Has anyone struggled or had issues with fingerprint sensor on s24 ultra. I keep on having issues, says unable to read. Put on sensor again and keeps on locking me out.

I shall resist further comments 😊

Yeah mines not always reliable on my S24U. Most of the time it's ok but I do get quite a few failures. I have the Samsung anti-reflective film protector and haven't yet increased the sensitivity. I thought that was more for glass protectors but will try it. I found too that saving two prints of the same finger definitely helps

Mines excellent but I don't use a screen protector. In saying that, it's been the most reliable one to date I've used.

I delete fingerprints. Turn touch sensitivity on. Add fingerprints. You may need to do this each time you add or remove a screen protector.

Mine is working with screen protector on the screen.
Try again to register your finger tip with the screen protector on the phone.

i was wondering if it's just me. i have the s24 ultra for almost a week. i have no issues with the fingerprint sensor before and after installing a screen protector. it's only today i realized there's been multiple errors whenever i am unlocking the phone. i even tried deleting all 4 fingerprint and re-registering them again. even so, it took a lot of attempts to even properly register that one fingerprint. 

i hope there will be an update soon to address this.

I have tried several times by deleting n re registering but nightmare with protector. Might need to invest in new protector or no protector 🤔

My experience has been that after I re-register, it works well for a few days and then it starts to get into this mode where I keep trying and I run out of the five tries. I think it is a flawed software. I actually returned my original s24 ultra to see if it would work better. And it did work really well for the first two days and today, it's doing the same thing where it's not responding. I tried everything but taking the screen protector off because I don't want to risk scratching the screen.

I posted the following earlier today ...

From watching YouTube videos, I use my same finger, actually my thumb, and create four profiles for the same finger.

I figure I'll have better luck when using that sensor since I have four profiles of the same finger. 

The problem, on this phone and even my previous phones, I was never completely satisfied with the outcomes.  On a fair percentage of times, my thumbprint didn't register on the first or even the second attempt. 

I now know why.  In Settings / Device care / Diagnostics / Phone Diagnostics / Fingerprint recognition, I practiced using my thumbprint and now realize what I was doing wrong.

I would typically use the top part of my thumb and the results were never fine; when I used the fat part of my thumb, I nailed it everytime.

If you're having issues with that fingerprint sensor, you can now practice using the built-in diagnostics.

Why didn't I think of this sooner. 

Just passing this on.
