Having the same issue too. I totally understand why it fails to recognize my face. Maybe it's just too bright for the camera to scan anything so I just use FP unlock when outside. Anyway, another user has raised this concern in Jai Mani's twitter account and said that he will look into it.

Well its not a problem.
Because sun also emits infrared radiation(lots of) , maybe it also interfere with our ir sensor,
For example :-
If your phone's front is directly facing sun and trying to unlock your device vise-vera. That ir sensor also picking up direct waves from sun and as well as incident waves from the face and unable to get proper data. I am definitely sure other phones with IR sensor also face this issue ( tested with galaxy s8+ it also doesn't work and iPhone will face this issue too).
P.S-If anyone find it wrong feel free to correct me and don't try to roast me with your incredible KNOWLEDGE!.

ir face unlock does not use camera. It use separate IR sensor which only pick up infrared wave(don't get confused with visible light. infrared is out of visible wave spectrum you can't see with naked eyes). Do a experiment hide your camera and try to unlock.
That left sensor is ir sensor and right is camera(which actually picks visible light).
Hey, have this phone from yesterday, europe dual sim version. How is for you the 3d face unlock?
I feel it's often inaccurate and in these cases it it does not unlock the phone.
Also, when i am in a dark room wit a good light behind me it's often inaccurate and, again, in these cases it it does not unlock the phone always.
In fact, if you try to register your face in this last condition you will see the face very very dark and this is a problem obviously for the face unlock.
I remember this last same "dark" problem also with the P20 Pro sensor.
What you think? Any solutions? Maybe in next updates?

just dont register your face in bad lighting conditions where it cannot be registered properly. I dont understand your problem tbh. Face unlock is a combination of the infrared thing and the camera.... if you use your phone while sitting in front of a bright light you cannot expect it to work. its like having wet or dirty fingers and comlpaining fingerprint isnt working.

.... behind of a bright light, as written in first post, in fact if i try to register face in this last condition face is almost dark, but in this case the infrared camera should not help anyway?
With my iphone x in the SAME condition the face unlock works ALWAYS instantly, so i can see the difference.

Well if you register your face in good lighting and the unlock does not work in good lighting then there is probably something wrong. You should contact huawei about that.
If you are trying to create a bad lighting condition on purpose and then it doesnt work I am not sure why you do this. There is no point. If you are in everyday live, like in a bar or pub and the lighting is bad you have to expect that face unlock is not going to be the most reliable. Its that simple. Sitting at home and trying to push it to its limits does not benefit you at all.
It is not as secure nor the same technology as face ID so there is no point in comparing them. If FaceID is better you have to accept it. No update can change the hardware.... maybe it will be optimized but it is not going to improve by 100%.
Surely ambient light has nothing to do with the face unlock method used here, as the camera is searching for an IR dot pattern. If anything, I'd expect it to work better in the dark.

It works in good light but it's not accurate like FaceID or also other 2D unlock tried until now. It's not accurate, for example, when I'm sitting in an armchair often it wants certain angles to unlock, etc..
I can understand your point about create "bad light condition". Until few days ago i had a One Plus 6 with 2D face unlock, but not only it, and in the same Mate 20 conditions i had no one single problem with angles or light behind me! Maybe it's a bit hard to explain..

In fact it is the same thing that I thought! "Better in the dark", but in the evening when there is an artificial light behind me, sitting in an armchair, the unlock starts to have a bit of difficulty. And instead it should be the opposite, it should work better.
In this situation if i try to register my face in fact i see my face really dark cause the light behind me goes exactly on the sensor. Same thing with P20 Pro sensor. Only with Huawei i have seen this "problem". Nor with Samsung, nor with One Plus nor with Pocophone, etc..
It's really strange.
Check the software/EMUI problem thread, see if anyone else is reporting it. Otherwise, it's news to me.

for comparison. I just tested bad lighting with my mate 10 pro... worked just fine... immediate unlock
i am not sure about the IR thing. it should definately work with no light but i am not sure if it is able to "work against" light. if your light sends out inrared wavelengths it will definately interfere with the IR projector. I am pretty sure though it sends out infrared wavelengths since it gets hot.... heat=infrared light (that how heat cameras work).

Apple were the first to introduce dot-mapping (or whatever they call the technology) to scan all areas, from left to right, of the face. The android versions on phones is more watered down...but it seems Huawei are using their own software of facial mapping which I imagine is designed to work the same as Face ID on Apple...but as there's some bugs with the pre-releases, I'd potentially wait and update the phone in 3-4 weeks to see if it resolve the issue.

It was perfect in my "condition" with mate 10 pro with light behind me and against the cam. Because it used only the frontal cam! When i tried to register my face with Mate 10 in "my condition" my face was no dark and clearly visible!
This IS a big difference and here there is an "error" starting from P20 Pro to Mate 20 Pro.

Yes, completely agree with you.
But i have a little doubt, this last comes from P20 PRO, also this with light behind me and against the sensor shows me my face all "dark" and obviously no update "fixed" this. I remember with this phone in my situation was IMPOSSIBLE use the 2D face unlock.
Idk honestly if an update here can improve this kind of sensor. I hope!

Facial recognition evidently hates sunlight. If your face is side on to the sun it won't work, you have to either be in shadow or directly in the sun. The fingerprint scanner I'm also finding to be very hit and miss. I have just been out using it to take some photos, lost count of the number of times both methods of unlocking didn't work.

Edit...
It seems to me like a directional or sensor spread issue,
If i hold the phone level with my eyes and head straight (straight neck) it works perfectly, if i'm at my desk with it in my hand looking down at it then it doesn't. If i raise my head and phone vertical as its giving me the 'recognising face' message then it unlocks just as i hit vertical/straight neck.
Problem is i look a t**t raising my phone every time i want to unlock it (looks like i'm checking myself out in a vanity mirror!!)
Had the iPhone XS before this and it worked flawlessly head down or not.
Can someone else who is having issues test this theory?

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.
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.

Doesn't work with the Spigen Ultra Hybrid flipped to the front.

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
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
I jave exactly same problem my old xiaomi 10 pro have better face unlock and faster than 23 ultra i hope i fix comming soon

Can confirm, the Xiaomi Mi 10 Pro is really fast and good with face unlock, Samsung has sucked with this for years, that's pretty much the only gripe I have with Samsung, their unreliable Face Unlock.

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.

Strange. It works perfectly and instantly for me.
Have you tried setting it up different distances from your face too? Bright light? Day light?
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.
