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.

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.

Hello, well I have noticed recently a strange behavior in the fingerprint sensor, but this behavior its always there (its not recently)
I have a pattern and the fingerprint enabled, but the fingerprint sensor only works when ths lockscreen displays the fingerprint logo, but here is the strange thing, the sensor recognize my fingerprint (because it vibrates once and ask for the pattern, if I put another finger its not registered, vibrate twice and doesnt ask for the pattern), I have already flash the phone several times, the first time I believe the sensor just doesnt recognize me, but later I discover this behavior and it looks like maybe a software bug
Something else notice these?
Is there a fix? its sometimes annoying
Thanks!

maybe its a hardware issue , i think u said u flashed ur phone several times? tried different ftf files? if thats the case , then its hardware issue. i havent heared that at all. the only issue i have seen before with the fingrprnt scanner is that sometimes it says an error but u reboot and its ok ( havent seen that for months though)

yes I have flashed it several times with the original and other ftf files (always respecting the model number), will try with a friends phone and see if this behavior happen there too
Latest firmware of Nordic Combined hasn't given this issue for more than a month now. Do a clean update I'd say.
Hello, I set up my finger prints and turned on the service but have found that it only works sometimes. When it does works it is extremely fast and useful. It will work anytime I touch it and then a couple minutes later touching the sensor won't do anything for a while. Then it will randomly work again later on. Is anyone else noticing this?
I've been very pleasantly surprised with the fingerprint sensor on my S8+ unit. That was the only thing people complained about before the release of the phone, but mine has been spot on 19/20 times. Maybe add a few more versions of your finger or try from scratch?
Try adding multiple fingerprints on the same finger. I also was surprised how amazing the fingerprint works. Very sensitive and VERY fast. But I added minimum of 3 fingerprints on my right index finger

Had this happen the other day. Pull-down gesture did not work either. Had to restart the phone. Lots of bugs in this device at launch apparently...
Same thing had happen to me. After a while it just stops working and have to reboot. Anyone know how we can bring this issue to light so it gets fixed? I tried turning off power saving in case the phone was actually killing the system app but it didn't work. Any solutions other than constantly rebooting
I've had similar thing happen today. Most of the time placing the finger on the sensor will unlock it right away. Today, my finger sat there and sat there, no error returned, but no scan either. It was just doing nothing. I tried a few times and it started working again. I'm using the Canadian S8+.
When the fingerprint sensor is apparently stuck, you could check the sensor status in the diagnostics: *#0*#
Hey there,
for about two weeks now I am noticing this strange issue: When I want to unlock my phone I touch the finger print scanner, the capacitive buttons light up but it takes sometimes more than a second before the screen lights up.
I am on Android Oreo, TWRP, S-on, stock firmware, magisk. This setup worked perfectly for many weeks now. I already cleared the cache partition.
Rebooting helps for a short while.
Does anybody have the same issue or has suggestions how to solve this or an idea what the cause might be?
Thanks a lot in advance!
Do you have a live wallpaper or an app that interferes with the lockscreen?
No and no.
I stumbled across another thing: using SD Maid improves the situation for a short while. Cleaning up the data bases seems to do the trick - for a half day or so...
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
to avoid mistakes
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..
Hello,
I have this phone for near 1 year and I always had this problem.
The problem is not happening very often but it happens by time on time.
It was happening more often before, when the phone stays with locked screen for a longer period.
But now it happens whenever it wants and I can't understand what could be the issue.
Maybe some process is failing by my opinion.
So the problem is that sometimes when I put my finger on the fingerprint icon on the screen while the phone is locked, nothing is happening, the fingerprint icon is not active and it doesn't read my finger. So I need to enter my pincode, the fingerprint sensor is just not working at all. When I unlock the phone with pincode and then lock it, the fingerprint is now working, until sometime later.
I'll be very thankful if someone can help me with this.
Thank you!

I believe that's by design. After a certain amount of time you're asked to login using you password. Once you've entered your password the timer gets reset.
I've seen this on other phones and it also happens on both of my 8Ts.

Thank you, Bill. This kinda answers my question, too bad there is no security option to define if you want this or no.
On my OP 8T the fingerprint stopped working well after gluing the protective glass. Without the glass it works fine.
