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.

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

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.

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. ?

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.
I had a S10e and honestly it was probably one of the best phones I have ever owned. The size was perfect, the cameras were excellent, and the best feature of all was the fingerprint sensor. It worked virtually 100% of the time, first time, no matter what. Sure Apple had face id, but it didn't really matter because the fingerprint sensor was so effortless.
I work with my hands, my hands are frequently dried out, or dirty. Frankly I never thought anything of this because it never created any issues.
I just upgraded to the s21 ultra because I wanted the new cameras and now I regret it.
The fingerprint sensor literally does not work. I have tried removing the TPU screen protector that I have on it. I have four fingerprints saved and they are all of my right thumb. And it literally won't work. every time I pull my phone out of my pocket it tries and tries until it locks itself. When I go to verify fingerprints it gets it maybe one out of 10 attempts. When I am trying to input fingerprints, half the time it says it can't even detect the finger on the screen.
Another major problem is glass screen protectors work much better and you can get a glass screen protector for an s10e for a dollar. You cannot put glass screen protectors on s21u without enormous expense and effort. And they still compromise the fingerprint sensor. The user experience of the s21u has been frankly absolutely terrible compared to the s10e.
And their face ID is completely useless as well. Most of the time it doesn't work and if you are in the dark or low light forget about it.
I really want this phone because of the camera lenses. The 10x lens really is amazing. 100x is probably what you can get to cropping images anyway.
but none of that matters because it's something that you use every once in awhile. You need to get into your phone hundreds of times a day. If they're access technology doesn't work in my opinion the phone is a bust.
It is driving me crazy.
Are they going to fix this or should I get rid of this thing and go back to an s10e?
Read the post literally right above yours about the 30 second fix. I've had many Samsung phones with the fingerprint sensor underneath the screen and I agree with you totally, it does not work. How this isn't the very first topic discussed on any phone review is beyond me. It should be class action lawsuit.
But, my fingerprint sensor works reasonably well now by doing the short 'fix' above. It wasn't targeted to fixing the fingerprint sensor, kind of a by-product. I suggest you give it a try, literally takes 30 seconds and can be reverted back in the same 30 seconds.
Worth a try, good luck.
I have recently got an S21 Exynos version and the fingerprint reader is useless.
I have the standard screen protector it came with on it and have tried training it multiple times and even doing the same finger more than once and the best I get is sometimes it works 80% of the time and then at other times of the day it'll fail 100%.
I'm not sure if it depends on if my hands are cold or warm and looking at my fingers my fingerprints don't look particularly pronounced but as it stands the phone may as well not have a fingerprint scanner.
Previous phones with dedicated fingerprint sensors have been better but never perfect.
Is this just me or do others have lots of problems too?
This is my first phone with an in-display fingerprint reader, and I certainly prefer ones like the one on my old Note 9, which were literally flawless.
That said, I would classify this one as "serviceable". It doesn't always work, though some of that might be my dry fingers/hands from all the washing and drier winter air. It seems to be improving in reliability as the weather warms and the air gets more humid. I do occasionally fail enough on the fingerprint that I have to enter my password, which is annoying to say the least.
Blowing warm, moist air on my fingers does tend to help, but then I tend to smudge up the screen a bit more. Oh well. Something I'll have to live with.

Sadly this doesn't seem to make any difference.
It's very erratic, sometimes it works several times in a row but at others it doesn't work at all for multiple attempts.
Very odd.
I've recently got my S21 and rather quickly found out that I have to push the screen very lightly and it works almost every time. To begin with I assumend that I had to push quite hard, but doing that it didn't work very well, so I stumpled on the light press tip. Anyone else with the same experiences?

It worked with the factory protector on it every time. No need to press deep or medium even. Just worked. Soon as a o removed this for some glass protection, boom. It simply will not work. And I've blown way too much money on protectors that do not work! Really sad, since I came from multiple Chinese budget flagships that do this perfectly. Since they use light instead of sound/vibrations.

I've switched from my trusty old Oneplus 5T to the S21 Exynos version, and I'm seriously regretting it. The fingerprint sensor is useless with or without a screen protector, and with Settings -> Display -> Touch Sensitivity turned on. I've deleted all fingerprints and rescanned them in multiple times (obviously after removing/applying a screen protector) and nothing works.

I've gone back to thin film for the display. It will not provide any drop protection but this way the fingerprint works of the time. Like it does without the protector. First time in many many years I'm skipping glass protection. I actively avoid curved displays and one reason for that is the glass protectors are horrible compared to flat display protectors.
I don't have any kind of screen on my S21 and so far (only had it a couple of days) the fingerprint sensor has been pretty reliable. I've even almost got to the point where I can wake up the phone by putting my finger in the right spot about 50% of them time (other times I need to tap the screen so it will show me where to put my finger).
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.

The best tip for getting it work I have seen is to use hand lotion. It really struggles with dry skin
Hi all,
I've noticed that a lot of times I get a "face doesn't match" message even in very good lighting conditions where I'd usually have no issues.
I tried turning the screen off and then on again to scan my face in the same position, and it can display "face doesn't match" 2-3 times in a row before being successful.
I noticed that I need to use my fingerprint much more than on my previous device, before my face wasn't registered only in very dark situations, and now even during the day it displays this message a lot.
Did anyone else experience this?
yes, +1
i initially blamed the whitestone dome glass protection, then energy ring app; but no, I guess the front camera is the culprit, poorer quality or poorer settings

Working fast and without any issues for me even at arms length. Try redoing face recognition in clear day light or with lights on, moving your face very slightly for different angles up down left right and then add the alternative one too.

I have tried all of the above suggestions, even before posting this thread. I also have alternative look added in the daylight. Since I used s21u before this one, I can definitelly say that there's something off about the face recognition on this device. I guess it's a software bug. With all the same settings it was working amazing on my s21u, even from an angle, in darker environments.
I'd suggest that we report this on samsung members app.
