This thread is created to find a fix to the Huawei Mate 9 fingerprint sensitivity (or lack there of) sensor issue, an issue that also plagues the Google Pixel phones.
Since upgrading to Android 8 I have found the registering a fingerprint with the phone is next to impossible. The sensitivity of the sensor has been cut down from Android 7.x. I have left messages to @HuaweiUSA in a DM to them and in the general public areas of Twitter. I have also posted this to other social venues.
Now, without resorting to rooting and changing a kernel file, I am asking others what can be done to fix this. Before you respond, please note:
1. Yes I cleaned the sensor
2. Yes my fingers are clean.
3. Yes I actually have fingerprints.
4. This thread is to see who else has this problem and to provide fixes/workarounds for those with the problem.
I do note that the fingerprint sensor does work somewhat well after to register your fingerprint. It is only the enrollment of a fingerprint that is the hardest.
If anyone has fixes, please note them here. Many thanks.
UPDATE: Huawei's official answer to the fingerprint sensor problem is to perform a factory reset after you upgraded your phone to Android 8.
Another issue that will affect fingerprint resolution: users REBRANDING their phone.
Huawei has specific firmware to specific brandings. So if you changed your C185 or C900 to C567 (or any other rebranding), you need to change back and then try the upgrade, reboot, factory reset method to fix things. Tech support said this would solve a number of issues beyond just fingerprint issues. Including call quality issues, networking, etc.
My wife updated her Mate 9 to Oreo using OTA, she received the 363 (C432) version directly.
After the update she lost her SD card, ringtones etc...
After a factory reset she struggled to get her fingerprints recognised, as if the phone could not "read" her finger. I did at the end but it was clear the sensor lost its sensitivity...When I tried to store my fingerprint in her phone it worked a lot better but still more difficult then on my Mate 9.
Her phone is an original German phone and not a rebranded model and the factory reset did not solve the issue...
So your not the only one facing this issue.
i use my m9 with OREO (b361) without problems so far! I have no recognition delays more than on my Honor 7 or my LG G5!
i did a factory reset after upgrading and have registered two fingers twice! This is a little bit tricky because often i got the notification that my finger was known by system. But it is possible to register every finger twice if you are a little bit patient.
Please try different finger positions too.
We tried different positions...I stated that compared to my mate 9 running on Oreo the mate 9 from my wife - also running on Oreo has a fingerprint reader who became less sensitive after the update. We have 2 mate 9's so we can compare both of them...
Our both mate 9 too.

How do I downgrade from android 8 (oero) to android 7 (nougat) ? I have serious problems with the fingerprint sensor after the upgrade.
Thanks.

Depending on your model, connect your phone to your PC annd open hi suite (if it doesn't automatically), click on update and if your model version is supported, you'll have an option to go back to an earlier build.
Couple things I find that works. About once a month (more if you use your phone more), I will take an alcohol wipe, and clean off the fingerprint sensor.
Next, I have found that once in a while, my index finger on my left hand is REALLY hard to use, but the index finger on my right hand is very fluid and fast. I simply go into the finger print settings, delete the one that isn't working well, recalibrate it and everything is good. Only had to do that once.
I find the sensor pretty fast, even the smallest portion of the finger seems to be registered and the phone opens, hundreds time per day.
BUUUUT, when trying to answer I call I have to rub my whole finger several seconds until it actually answers, I end up with a ringing phone on my ear waiting for it to recognize me.
I had the same problem after updating. Had to reset from factory and fingerprint management was impossible. It would vibrate after every try then fail. Tried dozen times, then factory reset again, same problem. Finally got it to work by pressing my index very hard against the sensor while rotating it. Took a few tries but it worked. Once it was recorded it now works perfectly. Strange. Hope it helps someone

Haha
cuz you need to hold your finger on sensor a few sec in order to answer calls xD

I rebranded my Mate 9, re-installed a factory image -- thank you FunkyDruid, and then the fingerprint menu settings disappeared. I would hate to format it if it's not gonna help.. Annoying though..
Soooo I did read on the forums like a few months ago that someone's phone fell and his fingerprint reader stopped working.
I fear that may have happened to my phone, it fell from bed height to the floor (it has a rubber case) and I just picked it, nothing happened anyways, so I tried using the fingerprint scanner but it didn't work so I figured my fingers were sweaty or something like that.
This morning I try to do the fingerprint recognition and none of them register (Left index finger & Right index finger).
If this is truly the case then my fingerprint scanner is rendered useless, does anyone know how I can possibly fix it or is it just a dead function now?
EDIT: I restarted the phone to see if that would fix the problem, and then I went into settings to check the recognition and if it works.
Lo and behold the Fingerprint ID management setting has disappeared from my categories in the settings!!! I tried searching it and it shows up, but when I tap on fingerprint management it just blacks out and sends me back to the settings menu.
W H Y T_T
Screenshot of my Settings menu after I restarted the phone, notice how the Fingerprint ID category is completely gone ;-;
Looks like the OS detects the fingerprint reader as broken, and so it hides the fingerprint menu as consequence since it automatically decides that it's useless... Sincerely, if the fingerprint reader is really broken, the only idea that comes in my mind (if you're still on warranty period) is make a try by contacting Huawei's service center in way to make them fix the scanner, but you don't want to tell'em that your phone's felt because in this case warranty won't cover you.

Thanks redskull, I'll try to contact them, I've been wondering if it maybe disconnected, or something of that sort.. because it just does not seem possible it can break from such a low height :/ I'll definitely try everything though.

I can't really now, but this phone surely isn't the best about making resistance to drops on the floor. It's always a mid-range device, so even if it carries good hardware and camera, hurts could often be a pain. Hope well for you!
Hey all,
I experience problems with the fingerprint sensor. It often doesn't recognize my finger on the first try but I need to try it several times before my finger is recognized. Or face unlock solves the issue and thus the finger print problem is avoided. I also deleted the finger print and set it up new several times but the problem persists.
Anybody else got the same problem?

Nope, my fingerprint sensor works perfectly fine.
Yours may be defective.
Take off the case from the phone. Make sure u scan ur finger correct.
If is not helping factory reset.
If is not helping call oneplus...open return due defective hardware
This finger print sensor reads much differently than what I am used to. For me it's literally a quick tap with my finger. If I hold like I would with Nexus 6p it won't read.
Sent from my [device_name] using XDA-Developers Legacy app
The sensor is really quite small and not perfect. I scanned the same finger three times (different parts of the tip) and now it works quite well. You will get occasional errors stating that the same finger has been scanned already, but if you keep trying it works
It's not a perfect sensor or even close, I've had to add a finger twice to get it to unlock properly most of the time. I add it as a new finger.

I bought the OnePlus 6 and I came from the OnePlus 3 and I ran into a similar issue. It helps if you input your fingerprint multiple times
For me its not that it doesn't recognize the finger, but sometimes it just doesn't even recognize that I have placed my finger on the sensor to check if it's mine. I have no idea why this happens
Mine works great. Sometimes I think it's even too sensitive, I turn the phone off and it comes back on when my finger is still in the vicinity of the sensor. Try to wipe it off with some mild water-dishwasher solution to get any dust/body oils off of it.

Are you running a custom kernel? I had this issue on Stock OS using Flash Kernel. Reflashing back to stock fixed it for me
My fingerprint recognition was always failing. The sensor was working because it would vibrate whenever I put my finger on the sensor but it never recognized it. I contacted OnePlus Support and the first thing they recommended is to see if there was an upgrade available. There was one - so I upgraded - not really thinking it would help at all. But miraculously, after the upgrade, fingerprint recognition works like a champ.
Try upgrading.

For me I had this same issue but not initially. The first 4 days I ran into zero issues. It worked every time. I then decided to start tinkering and installed the XXX mod. It wasn't quite what I was looking for so I decided to return to stock. At this point I flashed the stock rom via phone update menu. Then I factory reset and set up again. I noticed memory management issues and also problems with my fingerprint reader not recognizing my finger as easily. Re doing them didn't help. So I thought maybe I would use the fastboot method of restoring the software like the Nexus/Pixel roms. I did that and it flashed successfully but had the same issues. So I decided to manually flash each partition on both slots. Then I set up again. Still had issues. I figured at this point it was definitely a hardware issue because I felt I couldn't be any closer to a stock, out of the factory condition. But I was wrong. The msm tool that uses the Qualcomm drivers is the "Factory Image" I was looking for. It completely restored my phone to the condition it was when I unboxed it. I know logically there shouldn't be a difference but it flashed or fixed something on a certain partition that got changed when I was tinkering(I assume). So long story short. Try the msm tool if you think you have hardware issues before you rule out the software.
Fix-Fingerprint sensor not responsive
Entered to safe mode fixed the issue for me after a lot of trying to make it responsive.
Go into battery /battery optimization /hit the... Menu (advanced optimization) uncheck advanced optimization.
If on she is saving battery in sleep mode.
The issue you guys are describing is simular on rear sensors.
I did the above and it helped. Give it a try.
I have a problem with the fingerprint sensor.. Since I switched to miui 11 with android 10 the sensor worked at times. It works for a day or two, then the menu disappears from the settings and i can no longer use it.
I try tu update vendor partition, wipe data, format data, reinstall new rom with all wipes, reinstall stock rom with Mi FlashTool, any solution works..When i wipe all, it works for a while and than, suddenly, doesn't work anymore!!
I have Mix 2S, i'm sure that is not an hardware problem..
Replace fingerprint sensor
I don't know why you say that you're sure that it's not a hardware problem, but to me, it sounds like the sensor is broken. I suffered this issue in my own Mi Mix 2s and it was caused because the "cable" of the sensor was folded (it's not really a cable, it's more like a flat plastic connector) and it worked one day and not the next. I finally decided to fix it by myself, looking for a youtube video about disassembling the phone and with these tools and the replacement sensor it was pretty easy (and quite cheap, frankly). I hope it helps!

I had the same problem. Mi mix 2s had a problematic/bad assembly line.
I have exactly the same issue. After Android 10 update the fingerprint sensor works for a while. After one day I recognized that the fingerprint sensor is not working anymore. And there are no options or settings in the system settings anymore. So I assume a software problem.

This problem is very boring!!! Have you try a solution, or a temporary fix???
No, I have no idea how to fix. Seems we have to wait till the next update from Xiaomi, which hopefully will fix the problem. It is really boring.

Your assumption is wrong... these options will not show up if the system can't find the fingerprint sensor... Had the same problem and it turned out to be a hardware fault, exactly like mentioned by Kaliotto. You can do a simple test via CIT (tap multiple times on kernel-version). You will find a fingerprint sensor check in there. If it does not find the sensor, it is broken, simple as that. Replacing the sensor is really no voodoo, did it in a timeframe of 30 minutes myself and it was really the first time I ever opened a smartphone. And the parts are really cheap.

I read on differents sites a lot of people who had problems with fingerprint sensor after upgrading to miui 11 with android 10..i don't think that all of us had hardware problem at the same time of the upgrading, it's very strange...
so, to avoid any doubt, i'm searching a new fingerprint sensor..the site suggested in the second posts seems to have problems with payment, any times i try to buy with paypal o credit card, the payment was refused..so i'm searching another reliable site..
I solved the problem. In my case it was defenitely a software bug. I tried to run the fingerprint test at CIT and the phone reminded me that the phone is protected by a PIN and can not enroll fingerprint information. So I switched of the PIN protection and the fingerprint test runs positive. Since that time, the fingerprint options in the setting was back again and I was able to setup the fingerprint sensor as usually.
So I thing the deactivation of PIN protection was the solution to get the fingerprint sensor working again.

So, you only disabled pin in the lockscreen (and set swipe method to unlock the phone)??
I tried now disabling pin and restarted the phone, but no options in the settings menu
Can you give me more details? Thanks
Update! After one day of use, I have to say, that the fingerprint sensor still does not work proper. After a while the fingerprint sensor stops working again. I played around with the settings, disabled the PIN protection and start the phone several times and than the fingerprint sensor was working again for a while. There is still something wrong. Also the CIT test sometimes pass and sometimes fail. Maybe it is hardware failure after all.
What I did: I disabled the password (PIN) protection, means no protection at all. After that I was able to run the fingerprint sensor test at CIT ( as cdfs wrote). This test was pass and the settings to configure the fingerprint sensor appears again in the system settings and the sensor worked for a while.
Since this procedure the function of the sensor is not consistent and I can not definitely say what to do to get it works. In the meantime I think that all the described workaround just works by accident.
NEWS: i changed stock kernel with two modded kernel (Twisted v22 && LawRun9.0_60hz) and fingerprint start to works again!!!
So, my idea was real: it's a software problem!!!!
Try it yourself and give me your feedback
Hi,
I had also the issue that the fingerprint sensor was not recognized. I replaced it.
Then the option was there again but it doesn't read any fingerprints.
The CIT test fails by the last step "Pixel open test"
Then I got a second new fingerprint sensor and replaced it again.
The test fails again in the last step!
These are the CIT messages:
Autotest: Testing
SPI test: Success
Reset pin test: Success
Interrupt pin test: Sucess
Pixel open test: FAIL
So I would say it is a Software Issue
Hello,
so I at the end found some users, having exactly that problem!
I bought a new sensor and changed it. Pixel Opem Test failed.
I bought another sensor with the same result: Pixel Open Test failed.
Is there a usefull solution?

Hello currently I am using mi note 9 pro but I am having fingerprint issue there is fingerprint option missing I am not able to mange fingerprints. Plz somebody help me
Anybody get the fingerprint enrollment to work without sending phone back to OnePlus. I have tried just about every fix I can find on other threads with no success. I installed the latest OS 11.0.5.6 AA and I think it got worse. Can't even run the calibration tests. My fingerprint has been broken since I got the phone new from OnePlus. I don't really use it at the present but it would be nice to have working if I decide to sell phone later.
By broken do you mean its not detecting your fingerprint? are you using a screen protector? If you send it to OnePlus with a Lock on it they will refuse it and probably keep it if they follow Sammys practices...
never gets to the point of detecting fingerprint. just error message that enrollment not complete.
Is this only in the first set up screen or even when you go through the settings to ass fingers?
The only issue I have with my FP reader is sometimes when I first unlock the phone I have to place my finger/thumb directly center and use relatively firm pressure to get it to unlock. If I relock the phone (using double tap, or the power button) and then double tap to unlock right away the reader works much better. I am not sure why it only appears less reliable after the phone has been locked for some time...( i have not done any time lock experiments). Also, after the phone is unlocked and I use the FP reader for anything else...like a banking app, of whatever else...it works flawlessly and responds very quickly as expected. I am not sure why it only acts "funny" after being locked for some time. It's almost like something is going into a deep sleep while being locked???
At any rate, what you are describing sounds much different, even though it might somehow be related to the whole FP reader issues. If mine was acting as bad as your I would demand a return, repair, refund...whatever it takes to get the issue fixed.
Got it to work. I had pulled persist img when I first received the phone and unlocked. I flashed the old persist.img using fastbootd and got fingerprint to enroll. I use a tempered glass screen protector and it took awhile to get it enrolled but works good now that I have a fingerprint entered.
