Yes it works for me. I use the intelligent scan, only seems to call up the iris scan for passwords etc. Works well for me.

You have a screen protector installed? I have problems with iris scanning since I installed a milky one, even there are cutouts for the sensors...

No I don't have a screen protector fitted. I use a flip cover to protect it when not in use. The glass is scratch resistant so no need for a fitted screen protector.

That would be my word ... But I use this milky protector to have it more "like paper"

I use it as well, works reasonably well in good light. As long as you have the cutouts I wouldn't think that the protector would affect it.
I did notice that when I rescaned after a factory reset it took some work and good lighting but once I did that it seems to work in a fairly wide range of lighting...just not sitting in a darkened living room on the couch watching TV

I second the comment on reasonably well in good light with the caveat "after I take my eyeglasses off".
I've enabled it, but find only a few apps take advantage of it - many fewer than worked with the fingerprint reader on my Tab S2 or S7 Edge. My credit union account app works fine with fingerprint, but doesn't work with the iris scanner.

I use Intelligent Scan, and it works perfectly, even with my contacts in. When I'm wearing my glasses, I do have to lift them, but that's about it.
As for apps usage, we won't see a lot of that until Android Pie rolls out to these devices, as Pie enables the use by apps of biometrics beyond just fingerprints (once the app devs adopt the API)...

Note 10 plus fingerprint scanner issues

Got the phone few days ago. Most of the time, fingerprint works on first or second attempts. But now and then it takes 4-5 attempts. and on two occasions i had to try 8-9 times to get it to work. Is it a problem only i am facing or its a common problem? i already updated phone after buying. should i get it replaced or it will be ok with next update
Thanks.

common problem i think. not as fast as the previous one on N9

Well, it is not widespread or "common", some users complain about this, but this issue has been discussed at lenght since the first days of this device, do a search, you will find some useful tips, My sensor is very fast and accurate, I think it depends on several factors, temp, moisture, the way you registered the fingers, screen protectors, etc

Also, register the same finger multiple times... I believe you can add 5 fingerprints....

I understand what you are talking about. I was so frustrated with the phone when I first got it. I deleted all my finger prints and then set them up again. Make sure to slowly follow the fingerprint instructions when adding. I added multiple fingers and some more than once. I have not had any issues since. I have also read some people say remove the factory screen protector. I still have mine on with no issues. Good luck!

did you have the same issue as mine? like u had to make several attempts and sometimes even 8-9 times to make it work?

only time I've had problems with mine is when my hands have been extremely dry, putting slight moisture on my finger can make it scan better, but for the most part it works perfect unless I'm somewhere hot and dry.

I have similar issues when I have a screen protector on the phone. Sometimes I have to press multiple times, sometimes I have to press harder. Finally going without anything on the screen and the sensor works like a charm.

Screen touch sensitivity.
On my Note 10+ 5G (SM-N976U) I have a setting on the Display page (scroll down near the bottom) that increases touch sensitivity specifically for use with screen protectors. The screen itself is Gorilla Glass 6, which is twice as strong as Gorilla Glass 5, so, if you are the careful sort, you can get by without a glass protector. Even with an extra curved glass protector, with touch sensitivity turned up, I can use light gloves & still the capacitance works fine.

Touch sensitivity has nothing to do with the fingerprint sensor.

Mine works perfect with screen protector. Sure if you put new screen peotector, it takes time to recognise finger. But when protector sits perfect than no prob at all.

Mine drives me mad , adding finger prints mostly does not work , i cant record my thumb print at all , was wondering if the sensor is not correct under the screen ,its always hit or miss on my phone , with my wifes note 10 there are no problems

A hard reset solved the problem , it was not a complaint post i made but a comment on the fingerprint sensor, now fixed

I'm missing the iris scanner from the note 9.
Might send it back and go back to the 9

the sensor works well as long as you don't have dry hands, lick your finger/thumb and it will work every time, sad but true. it's something I realise after it working flawlessly while drinking in a beer garden with condensed glasses but the rest of the time it was hit and miss. seems if your skin is too dry it doesn't read well, but add a bit moisture and it works perfectly. guess it has something to do with the technology in the new sensor using vibration instead of imaging.

Yes, lick your finger everytime you want it to work in the midst of a pandemic that seems to be spread by the virus getting transmitted from the hands to the face everytime you touch it...

Excellent advice from ultramag69, this mostly solved my problem, but I'm not happy with Samsung, This problem should not happen on such an expensive device from a famous brand

The other advice I've found is to set up multiple finger prints with the same finger (you can usually set 5 fingerprints). This will improve the hit rate of the fingerprint sensor...

Fingerprint scanner patch/kernel

This is a great phone but the fingerprint scanner sucks. I fully updated to all the current security patches but the scanner still is hit or miss.
Are there any kernels or patches developed to help fix this issue?
Is the scanner issue a software or hardware problem?

Personally i dont have much issues with it, it's not the fastest one sure but it recognizes fp correctly like 99% of the time.. are you using screen protector?

My A50 came with a screen protector on it. I did some looking around and there are a few that claim to work better than the default one. I'll take it off and give it a try but I prefer to have the screen protector on.

A50s and A51 seem to have a faster one, so this is it.

Do you know if it was a hardware change or software upgrade?

Funny thing is I use the Whatsapp fingerprint scanner to unlock my Whatsapp and it works GREAT! Literally its a difference between night and day. Why does it work better with an app and not the system?

Question Finger print scanner

Hi everyone, I have a pixel 6 pro. Yesterday I fitted a screen protector liquid glass. I have problem now with a finger print scanner. Finger print scanner don't recognize finger print. Some one have this issue ?
I deleted old 4 seved finger prints and create new. Didn't help
Name of screen protector
For Google Pixel 6 Pro (6.7") UV Liquid Glass Screen Protector By Optimum Shield

I have no experience with the specific brand you used, all I can say is that I use a Moccolo UV Glass protector without any issues - I even had no need to activate higher screen sensitivity ....
This would be the first I'd try in your case - you find this under the display settings
If this still doesn't work at all I fear there must be something either wrong with the protector itself or with the installation (maybe some bubbles in the area of the FP reader)....

Not another FPR thread?? How many do you need to figure this out? You think you can find the answer in one of these of a dozen threads?

Question Hard time with fingerprint

Just bought S22 6.1" and fingerprint scanner is failing a lot with me. My S21 I don't even have to press hard and it is rare to miss with it.
I have model S901E with snapdragon, on AVA7.

Same phone but what's S901E - isn't that 1U? Anyways, the fp sensor is perfectly accurate on mine, an instant reaction.

I'm from Brasil. I guess S901E is for snapdragon version outside USA. That's the first time we get snapdragon here in Brazil.

Good to know, never saw the E on galaxy models before. And you have problems the fp sensor? I hated it on S10 models but that was different sensor, the current one worked fine on my S21 and now the S22 sensor is perfect too. I registered twice my right hand thumb and 2x right index finger they both work with even a short touch.

On my S21, it just needed a light touch with a very light press. But now I realize one thing. I did not pill off the screen protector that came with S22. In fact, it is not a screen protector for daily use. Do you think it is the reason fingerprint is worse than s10

yes, that plastic foil wrap won't let the scanner read your fingerprint. It's not optical but rather like a mini radar scanning the print ridges on your finger tip.

S21 came with screen protector, but a real one. Simple but it did the job. And fingerprint worked perfectly. I thought I could keep this upper plastic that came with s22 until my screen protector was delivered. I'm gonna try without it.

I exchanged my S22 yesterday because the fingerprint sensor was failing so often (plus random, 20 minute long network disconnects). I lost my preorder storage upgrade, but the new device works perfectly.

have you tried to remove current fingerprints and add new ones?

With a screen protector, it failed every time for me.
I'm using the Omotion that I bought on Amazon.
I did try removing the current prints and adding new ones with little luck. In this case it will work 1 in 10 tries if you press very hard.
Remove screen protector, works perfectly.
As I'm looking for another screen protector, I'm checking reviews for any comments on "fingerprint"

Go with the Amfilm "Hybrid" glass. Glass still works poorly on Ultrasonic sensors, so you want a TPU or "hybrid" (semi-hard plastic) protector to have it work properly. These are the same material (and IMHO better quality) than the Zagg protectors they're trying to charge $50 for.

Also you can increase the touch sensitivity. My scanner is hit or miss with my glass protector but I'd take protection over the fingerprint scanner. I wish Samsung went optical and this wouldn't be an issue.
