Well, looks strange, is ultrasonic so has nothing to do with the case... i think is fake but who knows

I'm calling BS on that story. How can a case affect the workings of the fingerprint reader?

YEAH, that was my first thought also. I could almost see it if it was a S10e but there'd have to be some serious crap going on for a case to defeat a screen reader.

Well only one way to find out buy $3 case and do it our self....

This is an old problem, which occurred 2 month after the official release of this phone to the market. I was able to repro it back in April on my S10, but after 1/2 months all had been fixed.
In every case remember that protective glass not compatible with ultrasonic fingerprint require more pressure on the screen, and this translates into less accuracy in saving and reading the finger data.

(Updated with new link.)

So it wasn't a gel case then and a screen protector. That makes more sense now as you can see how the screen protector can affect the fingerprint reader. Just tested mine to be sure and only the registered fingerprint can unlock it.

Same here. I tried all my fingers and only the 2 registered fingers can unlock my phone. I kept the factory installed screen protector on for a day before I finally couldn't stand it anymore and removed it. Even with the factory installed screen protector, I still could only unlock my phone with the 2 registered fingers.

SAMSUNG confirmed From Discover on Google https://www.sammobile.com/news/majo...print-flaw-will-be-fixed-with-software-update

I don't see it as a big problem when the phone first came out. If XDA is a good representation then the fingerprint reader didn't even work for the owners own fingers, much less a stranger's. ?

This. Sad, but very true.

S10e unaffected?

If I understand the reports correctly, the following has happened:
You install a screen protector and THEN register your prints. The sensor "reads" the structure of the protector, not your prints. Hence, it does not matter, what finger is used as the protector unlocks the phone. However, this also means - as I understand it - that if you register you fingerprints with Samsung's or another protector that does not have the problem (or without any screen protecor), you are safe. The reports sound as if anybody could just unlock your phone by using a $3 screen protector. That is not the case, as I understand it. So basically, just try if you can unlock your phone with fingers you have not registered. If that does not work, you are safe.
Please correct me if I am wrong.
EDIT: The videos in the link below seem to suggest otherwise...

https://mobile.twitter.com/Sta_Light_/status/1184844865730801664
It effects the Samsung Galaxy Tab s6 which uses an optical fingerprint sensor. The ultrasonic and the optical sensors are entirely different. So it has to be a software bug. Which can be patched.

Just tried this with mine using two cases and thankfully it doesn't unlock. Weird bug
I've disabled fingerprint authentication for my payment & banking apps just to be safe and set them to use the good old pin.

Samsung will start rolling out the fix for this issue within the next 24 hours apparently.

Got the update!

I'm sorry, I posted this in another thread, but I will also ask here.
Does anyone know this:
If you are with the factory applied screen protector, do you have to also remove it and re-register your fingerprints after updating? Or this is only for other screen protectors (silicone)?
It's not very clear from the update explanation.

The initial statement from Samsung that I read said it was only for third party screen protectors. I did see another one that said all screen protectors, so yeah that is a little confusing.
The initial story I read said it was from a cheap screen protector then there was another story that said it was a cheap silicone case then it switched again to a cheap screen protector. Then the statement from Samsung was about screen protectors. Definite confusion. I removed the factory installed one after a day because I could feel the edge every time I swiped up or from the side and it annoyed me.

Underscreen fingerprint sensor for Mi9 unlocks with any fingerprint ...

So in case Mi9 users didn't see this, Samsung is having similar issues with their S10. When I saw the news about Samsung, I tried and tested this on my Mi9 and low and behold it unlocks with any of my fingers if I put the included silicone cover on top of the screen. Of course it doesn't work when the cover is not over the screen.
Any Mi9 users care to do the test? I bet all the Mi9 phones come with that thin silicone cover included in the box.
P.S. Also worth mentioning I have a screen protector on as well. I heard some screen protectors can cause this issue as well (seems it isn't the case with mine).
Hi, bro
I don't have this problem.
I use a glass Screen protector.
Miui 11.1 by xiaomi.eu 9.10.17
I think you misunderstood what I meant to say. I'm not talking about the screen protector.
Put a thin silicone case over the phone's screen and put any finger that is not registered over the sensor area. The phone will unlock.
Read here if I wasn't clear enough. Same issue applies to Mi9.
https://www.gsmarena.com/samsung_is...t_vulnerability_on_s10__note10-news-39708.php
I get it.
I tried that and it didn't unlock
Doesn't work with the Spigen Ultra Hybrid flipped to the front.
MI 9 / xiaomi.eu 9.10.17
Does not work at all. Perhaps this is only a Samsung problem?

Doesn't work on mine device too , with either registrated fingerprint or not , it's doesn't unlock at all with any finger when my stock cover that comes with the device.
Samsung ultrasonic?
Xiaomi optical?
Got notification from my bank app that fingerprint login for s10/note 10 is disabled, for mi 9 no restrictions.
You got me curious so I put the case on the phone the other way around so it covers the screen but the fp sensor doesn't work at all for me, correct fingers or not. Tried quite a few times like this and also with the back of the case on the screen, it always fails or in the case of putting the back of the case on the screen, it says the finger was moved too fas even though there's no movement at all. Quite odd if it unlocks like that for you, thought only ultrasonic sensors have that issue, I also don't think the screen protector causes it but I don't have any so can't say for sure.
My screen was replaced in like day two after buying the phone because it turned all green. Mi store here in Romania refused to give me a new phone. Could this be the cause of why this happens for me?

Do you have face unlock enabled?
Because when your Phone is unlocked via face unlock you can put any fingers on the fingerprint sensor and your phone will change to the Homescreen

In my case this is not true!
I have face unlock enabled and fingerprint sensor is working as it should!
I can unlock only with dedicated and memorized fingerprints regardless activated face unlock function!
Also, as I can see, title of this thread is little unfair to Mi9 because author in latest posts say that his phone screen is replaced!
After such big replacement I believe that factor reset procedure should be done because every peripheral have is unique ID and if this ID is not correctly recognized and maybe ID value from old sensor is used then all this "blind" recognition doesn't surprises me.

Hello! I have the same problem, I discovered it a few days ago. It is unlocked with any finger.
Doesn't affect my phone. With the silicone case from the back over the front, only the correct finger(s) will unlock the phone.
It works fine on my mi9. In addition, Samsung has a different type of reader, as its predecessors have already mentioned.
The samsung problem is simple, it has the tolerance set too high, this is because SS want to have a better "usability" of the reader.
Buuuuuut, it backfired.
They have to think a little and know that people will uncover this trick to have a "better reader".
This can happen in any sort of reader, it's only a matter of parameters in software.
Hello guys, I'm so pissed off my gf in front of me unlocked my mi9 with any finger ! I'm not surprised that she did it, but everyone can do it, even thief ... It's crazy but I did fingerprints registered reset and now it looks like it works ... But ... I think I have lost my faith in mi9
I tried with 3 different silicon cover on a Mi9.
It does not work.
mi 9 is optical, not ultrasonic

General Hey Google: Acknowledge & Fix The Fingerprint Scanner

11-9-2021 - RETURNING DEVICE
I’ve given it some time to try screen different screen protectors but the nail in the coffin for me is Googles response to how bad the fingerprint scanner is. I can’t accept that as a answer with no foreseeable fixes or updates.
*****************************************
Tempered glass on and off....I've tried all the tips and tricks floating around from Google and YouTubers. The fingerprint scanner just seems to be bad all together. About 4/5 out of 10 times it recognizes my finger. When it does it's super slow.
A update went out last night that people are saying solved the issue...…It has not.
How have you dealt with or solved the issue at hand?
So far no problem with my fingerprint scanner.
One thing you could try (if you haven't done that already) is to make multiple scans for the same finger.
I made 2 for my right thumb, 2 for my right index finger and 1 for my left thumb. So far no problems... Hope that it will get better for you soon
I hate to be that guy, but my fp scanner is flawless on the Pixel 6 (at least as snappy as the OP6T was). Keep in mind, I don't use a screen protector.

I've no issues with it either also coming from OP6T. Registered prints twice and made sure to scan different areas including edges. Works perfectly and is quick enough for me
No issues on my end. I have a cheap screen protector on to. It's slow but it's been working. And I have the driest hands ever.
I've got a screen protector on and it always reads my index finger 100% since day 1.
But initially it read my thumb only 50% of the time, until I figured out that setting up prints initially makes all the difference.
Even before the November OTA fix (which I sideloaded as it was not coming through as OTA), I got it working.
Now its's almost as nice as on my 4a(5G) which is 100% accurate.
Here's a Link to my method.
I am using the ivoler tempered glass screen protector and I can never get the fingerprint reader to work.
If you have a functional finger print reader and using a screen protector, what brand is it?
i'm using tempered glass and can't get it to read. thinking about taking it off.

I had the same issues. The update didn't improve things either. I then had to factory reset (for other reasons) and FP reading is now running really well. This is with the 'difficult' spigen glass align master protector. Have yet to test it in daylight though and suspect it won't work quite as well.
After reading through everyone's post....didn't want to quote everyone but:
-Registered every angle of my finger whether thumb or index. 2 registered per same finger.
-Turned on Sensitive Touch or whatever it's called for Screen Protectors
-Turned Always on Display on to keep the fingerprint there without double tap
-Removed Screen Protector
-Updated phone
I'm also using ivoler tempered glass.
Don't think I'm missing anything else.
Only thing left to do that I saw someone did was go a Factory Reset.

I believe that people are struggling with the fingerprint reader.
That being said, I have had no issues with my P6. I don't have a screen protector on it. It reads my finger print 90-95% of the time when I press and hold my finger on the scanner until it unlocks (about 1 second). I've never had a in-screen reader, but it is certainly not a "tap the finger" on the reader like some phones are. If you are coming from an ultrasonic reader, you will have to reteach yourself to "touch and hold."
It reads my thumb too just fine. Be sure to watch how your thumb typically hits the sensor (for me it is more of the side of the thumb when I am holding the phone in one hand) and be sure to emphasis that area of the thumb when setting it up - but be sure to scan the entire finger/thumb too.
I've only saved my left thumb and right index finger once each (there are only "two fingerprints added" on my phone right now and everything works very reliably with either finger.

I agree. I normally put a screen protector on my phones as soon as I get them. However, I think we are just going to have to wait to see what works with the optical fingerprint scanner and what doesn't. This isn't just a P6 issue however. Tempered glass protectors (my go to choice previously) are unfortunately notoriously bad with optical scanners.

I agree, but at this time I will get frustrated with the phone and hope the screen protector works if and when I drop it.
I've had tempered glass screen protectors on optic in screen scanners. This could be a simple case of trial and error. I have more protectors coming in to see. I also have 10 days left to return this device if nothing solves the issue. Taking the screen protector off is out of the question.
The fingerprint scanner is by far my the worst thing on this phone. It's just as bad as the one on my Galaxy tab s7+. But I'm sure it can be fixed with an update. It's just ridiculously slow.

Question Fingerprint recognition :- Improvement

Hi all, those who are struggling with the fingerprint unlock, have you followed the instructions given when adding them? Having done it plenty of times I didn't even bother to look at them, I know best .
Thought I would have another go at adding them, this time I read the instructions and put the part of the finger on it asks for and although still not the fastest, it's far more accurate than it was before.
I guess you did not look at the other four threads on this topic either.
Fingerprint unlock is fine for me. It's not instant, but its faster than my old mate 20 pro ! I'm sure face unlock is just round the corner though.

Question FingerPrint Reader Woes w/Whitestone Dome Glass

Sunday night updated to the Jan security update on the Pixel 6. Prior to that, the finger print reader was working (but barely). I got distracted and forgot to check how the fingerprint recognition was working. The next day, forgot completely about the update and installed the Whitestone dome protector (which went mostly good but I've got three small bubbles, but that's another story).
After installing the dome, they recommend retraining the reader. However, even after training with multiple fingers, the reader, very, very rarely works probably less than 1% of the time if even that. Any ideas what I could try to improve the accuracy? The January update seems to have improved accuracy for most people. I just wish I had tested out the January update more thoroughly before adding the screen protector.
I bought the Dome glass,too. After replace it with the old glass protection the fingerprint was worse than before.
I trained the new, but not better.
What helped for me was to train the FPS again with more pressure of the finger on the FPS. Now it's working almost like the old protection.

I just installed the Whitestone Dome yesterday. My fingerprint seemed to work the same but I went ahead and did a retrain. I think it is still close to without it (WD) except for 1 finger. I had an issue with that same finger on my old OP6T. Good Luck.
I also installed yesterday Whitestone Dome, the fingerprint reader works just like before almost every time. I never had any problems with the FPR, it only failed when I lifted the thumb to early. I did not retrain my thumb, increased Touch sensivity is still disabled. I don't know if it matters, but 4 finger profiles are my thumb.

It's a known issue ever since launch and nothing seems to be working out. I've enrolled 6 fingerprints and success rate is less than 50% first time. I gave up on this after using it for couple of weeks and accepted the fact that there's no solution.

I'm on a P6a but probably similar situations. I was even worse with about 25% success rate and couldn't even add a FP. I signed up for QPR1 Beta 1 yesterday and the FPR is flawless. 100% in the time I have it running (other than missing the sensor half way once). It basically fixes it. FP added as well and it works.
Thanks for the update. I have beta update available but haven't installed it yet. Let me do it over the weekend.
FWIW, I have been using an IQShield screen protector on my Pixel 6 without issue. Close to 100% success rate for fingerprints. I'm really curious what causes some people to experience problems, and others not.
I'm starting to wonder if this is a per-device thing or something. I got mine a few days ago and have been using it constantly, and it hasn't missed a fingerprint read yet.
Out of curiosity, do y'all have dry skin or something? I wonder if it has anything to do with how well your fingertip flattens against the glass.
Well, after installing the latest beta QPR 1, this issue is resolved.. 100% success rate

No dry skin or other issues coz I've been using onscreen fingerprin from ages but definitely device issue i guess, which is now resolved.

I took advise on the beta. Opt in. Fingerprint works great. Never ever use the privacy screen protector either. That blocks the fingerprint, and enrollment.
Since the June update, never had any issue with the fingerprint again. Before it was hit and miss.
You guys have the Pixel 6a?
Cheers
The two best tricks I am aware of are:
-Registering the same finger more than once
-Using hand lotion frequently to avoid dry skin
