You can see what the fingerprint camera sees by searching it in “activity launcher” app.

That’s neat!
Download “activity launcher”, search for “fingerprint” and select what I selected on the video. Keep in mind you need an amoled phone with an in display fingerprint.
Lol cool!

NICE
It’s only for in display ?
I accidentally moved the ring while trying, are the default X and Y the same as the video shows?(mi9t)
I also did but I went back and it reseted itself. This must be just the manufacturer’s tool for debugging the sensor.
Probably. I don’t have a device with a side or back mounted sensor. Furthermore, these sensors are capacitive and not optical as in-display ones.
You’re right, thanks 🙂
What the fuck fingerprint has a fucking camera?
Not all fingerprint scanners, just the in display ones. They effectively take a photo of your thumb every time you unlock the device. It’s a specific camera just for that work.
Additional info: Samsung phones use ultrasonic scanners, these are not optical.
Ultrasonic are supported by latest Snapdragon processors like sd 865 right?
It doesn’t matter what proccesor it is. They use it on their S and Note line.
But not because of the .5mp 3fps super shitty fingerprint camera that sees absolutely nothing of interest
Ohh… Thanks.
Not showing up on my POCO f2 pro. Do I need root?
Edit. I installed the app but there is no “in display fingerprint scanner” is what I mean.
Except your fingerprint
Damn man..
I’m not gonna going to bathroom with my phone ever again..
There’s no in-display fingerprint option in OnePlus 7.
This requires a rooted device i assume?
You can probably find info if you google search it. I don’t see why, if it’s available, it requires root though. It’s just testing software as it looks. (I didn’t press any of the other stuff in there because the last think I want is a broken fingerprint scanner).
I did it on my nova launcher 👍🏽😁
I wonder what image out of the depth sensor would look like.
That’s quite cool! Thnx
In my country they take our fingerprints when we get an ID card. I have had one since I was 16. This is Macedonia btw, do they not take fingerprints in NA or is that a USA thing?
imagine this post got spread out from here…how people will react about xiomi phone…huhuhhhuhu
I don’t see that. The sensor (camera) is made to focus on 10mm. It can’t see anything else that what is touching the glass. So yeah, it can’t be used for anything else.
Because that’s a Xiaomi/Miui tool.
COOL
*North Macedonia. Macedonia is a region in Greece.
You must be fun at nationalist parties.
Few months ago I’ve wondered if this was possible but didn’t find anything. Thanks a lot for this. 🙏🏻
i dont have same app in mi note 10 ,when i look up for package name spp called delmar fingerprint pops up and it doesnt have such feature
I have redmi note 7 pro and once I was trying a camera app which supported pro controls and it recognised the depth sensor as an ultra wide camera. It looks like a typical 2mp camera
Well, You have to call it by its name.
WOW
I always wondered whether this was possible.
You’re using a mi9t right? Did you try changing the sensor color ?
Do you know what camera app it was?
Yes, it’s the 9t. No, I didn’t change anything.
I see the option to change colour in OPs video but not sure that’s a good idea even if possible. There are more shades to the green spectrum and allows more definition to be shown. Same reason most night vision goggles use green light.
that’s really interesting! I finally figured out how my 9t does the ambient light sensing. So it was through the fp sensor! smart
I think they can use it but they aren’t. The ambient light sensor in at the top of the device. Test it by covering it with something when in a bright environment.
They could use it as a secondary sensor to have more accurate results though.
Gei
BE CAREFUL! Tried it on my Poco F2 Pro, couldn’t find the view from the OP, but I wen’t through some calibration menus and now my FP sensor stopped working. It doesn’t recognise existing fingerprints and crashes when trying to add a new one.
This sucks. I didn’t run anything else there for this reason. Maybe there is a way you can make it work again. Hope you fix this.
I’m sure it’s fixable when I get a bit of time, but I wouldn’t recommend people to play with it.
Yeah neither
What app¿
Don’t exactly remember
Well that’s just silly. When you took your camera to the bathroom before… Did you ever notice the high quality front and back facing cameras? All of a sudden the shitty in display camera is your problem?
I don’t see why you are getting downvoted. I doubt there are people actually from there for whom this is a touchy subject downvoting you. As a neutral foreigner, I agree that we have to call places by their official names.
Hey can you post the color settings I messed mine up
Sure, it’s Green at 255. Red and blue are at 0.
Thanks I had cranked up red and blue
Was the fingerprint reading not working? I’m curious.
Working still I had even at one point turned them all to 0 and still worked
I believe this affects only the reading inside that app. If you noticed, you can enroll fingerprints inside the tool.
Yeah for the authentication testing. My unlock speed still remains within the 230 -270 milliseconds
Yes, because unlike the classic fingerprint scanners, these in-display ones are just cameras taking a high quality picture of your fingerprint and then matching it with the saved data.
Where can I find this, my mi 9 lite is on evox and it has a working fingerprint scanner, so it’s definitely somewhere, but where?
Have you heard the saying ” Truth hurts “?
That’s the reason.
Wow that’s cool!
I downloaded on mi 10 pro but can’t see in display option just comes up with Delmar I’m not sure how to properly find this but want to badly
Can you please extract apk of In-Display Fingerprint?
Can confirm. Verified to be working on Redmi K20 Pro.
It’s a serious security vulnerability! Not cool Xiaomi.
I never thought that in-display fingerprint scanner is a literal camera as opposed to other forms of sensor
I did selfie with that lol.
I don’t use my cameras to scan my biometric data or secure my phone or make financial transactions.
So you are saying, you can get your iris scan data on samsung phone? or FaceID scan on iPhone?
There are many ways of exploiting this vulnerability, say a rouge application pretending to be a lock screen asks for a fingerprint and unknowingly you give it. The app can then send this fingerprint data to a remote server.
You were saying that the code is different for different processes : activation of sensor, validation of the fingerprint captured.
I hope they are different. But I was able to snap a screenshot of my fingerprint when accessing the fingerprint scanner. So, I don’t think it’s going to matter if you can access the secure stored fingerprint.
Interesting, analog seems so far away. We use a digital thing and it’s the greasiest fingerprint sensor I’ve ever used lol.
This is “bug” the also appears on Mi 9T Pro!
Welp I was born in Macedonia and I don’t agree with the name change. Or the flag change. Or the constitution change. I mean it’s not like it’s not our generations fault, it is, but this country is so corrupted that even the ones who organized the “coup” on the 27th were working for the same people the people in power worked for. I mean it’s actually impossible to enter the pairlament, as it has steel bulletproof doors with panic buttons and things. Those people were let in intentionally, just to see who had the balls to fight back, and they’re all doing time for terrorism now so yeah. Also if you follow the current situation, why do you think that the current party got reelected? Because the opposition didn’t do anything when the time to vote for it came, and people are more mad at them then the ones that actually changed the name. TL;DR We’re fucked no matter what name we have, and we’re probably going to be dissolved within 25 years, so you can chill about the name buddy, it really won’t matter in a bit.
The first point is irrelevant. The second point about rogue apps doesn’t have to be phishing scam, it would be a legit app with hidden “functionality”. And let me remind you that you cannot change fingerprints like your normal passwords.
To anyone concerned about their security, it’s probably just a calibration tool
For me it doesn’t require root. I haven’t rooted, and it works perfectly fine. It is fun to see how they convert your fingerprint into an image (I assume equivilant of a hashed password but for images)
It is possible, but it only changes inside the app, not the OS. Blue worked for me, but not red. Blue was really hard to set up and didn twork on existing fingerprints I set up in the app though
Try [this app](https://play.google.com/store/apps/details?id=com.lb.app_manager), choose to show system apps, choose to create a shortcut on the “Settings” app, search “fingerprint” and choose what he chose.
Same in mi9se probably all xiaomi with optic fingerprint scanner. Nice..
Have you tried factory resetting the phone?
I wonder if that could fix the scanner.
I fixed it in the meantime by going through the menu again and rebooting
That’s not the problem, the problem is by CDD this access shouldn’t not be possible even for the kernel so an application with this access it’s a major security flaw. Only the TEE can access to fingerprint data.
A technology website in my country wrote an article about you doing this
https://www.geektime.co.il/redditor-gets-access-to-the-camera-in-optic-fingerprint-sensor-xiaomi-mi-9t/ (in Hebrew sorry)
Actually, if you search for “xiaomi fingerprint camera” there are a lot of articles about it. Surprisingly it made it everywhere.
Already appeared on gopgle news feed 😂
lolz…someone stalk this sub
Same in Mi A3 :/ OEM forgot to lock 🔐 FP sensor
it’s not a bug it’s a feature 🙈
Checked 9T pro version. Doesn’t seem to be the case for me
UPD. taking it back. I tried waving toothpick in front of it – it kinda shows on the scren. But the effective range and quality is VERY limited
cool
Can these cameras for the screen fingerprint actually look at you?
Can you see the sensor under the display?
I can’t remember since there have been years since I had that phone.
