Fingerprint Sensor Glitch - OnePlus 6T Questions & Answers

Currently testing on Tmo 6T - I am able to unlock my device with my middle finger knuckle -
This works 6 out of 10 times. I was also able to unlock using my daughter's knuckle. Has anyone else tested/experienced this. I saw that some other people have been able to unlock using fingers that arent registered by using just the edges.
I do not have smart / face unlock enabled. Nor my knuckles registered

My knuckles are not unlocking my phone. Are you pressing it straight on? I tried with a few different knuckles.....

Using my right hand, my middle finger knuckle works best to do this, I place at the top of the with a slight left right motion with it's lighting up.

My knuckle isn't working on my phone

Correction, its not the knuckle, the correct term is the proximal phalangeal Joint. The main bend in your finger. That portion unlocks my phone. I tried on my sisters device same thing. This is done using the skin portion, not the underside of the hand

Still not working here.
Bit annoying to test because of the awesome face unlock ?
But try to delete an retrain your fingerprints. Maybe you have a simple bug here

Only my fingerprints unlock my phone.

OP, check to make sure Google Smart Lock is not enabled. This is often the reason for cases like this so I'm guessing that's why you're able to bypass the security as well.

Discussion about this bug is going on for some days now over at Oneplus Community:
https://forums.oneplus.com/threads/fingerprint-massive-bug-other-people-can-unlock-the-phone.941931/
Only a few have yet encountered this issues, me counting

Doesn't work for me

I would guess that it's not a sensor problem but a problem/bug within the algorithm. Either this happens when enrolling the print or when the algorithm is trying to improve/learn reading your print. Maybe there is one point where the accepted pattern gets too vage, thus allowing even non-finger parts of the body as well as different prints?

Edit. Face-unlock was overriding the fingerprint/knuckle attempts in my case.

Fingerprint scanner

I assume the normal usage, at least what Sony intended, is to first wake the phone by pressing the power button, followed by screen unlock, done by fingerprint scanner.
You can bypass the screen unlock for a period of time, configurable under security settings, by selecting various screen unlock timeouts.
Isn't anybody else bothered by this two steps unlock, isn't it possible to be done in one step only? Is Sony even considering to change or allow one step unlock?
To me this is becoming older by the minute to the point I completely disabled this feature. Not to mention, the fingerprint reader sensor needs multiple reads to get it right. (of course, I have reconfigured the sensor by inputting what I hoped a wider finger area, didn't get better)

I can do it in one go. Hold power with registered finger in the right location and phone unlocks shortly after depressing power button, i.e. fingerprints are read whether or not the power button is depressed. Your sensor requiring multiple reads is probably why this isn't working for you.
I've read that the sensor doesn't work well for many people and I've experienced how damp fingers don't really work either. My fingers are not the greasy type (too dry more like) so maybe this is a factor for some...
You're right, it works, although, not all the times unfortunately. In like 10 tries got it to unlock directly 2 times. Well, at least the functionality is there, thanks for your answer.

youre right it doesnt open in 10 times , 3 times it works, me having a slightly damp finger, it refuses to open, i just hope Sony guys have a work around for this??.. or is the finger print reader ther for namesake ??.... it doesnt work that well for me !!
I'm having the same problem. Moist fingers decrease the recognition of the finger print sensor. But I could improve the detection rate a bit. I've registered my mainly used finger twice. Once dry and once moist. Did help I think.
Mine is working suprisingly well, although i have only used my right thumb for it.
I have no trouble unlocking it with muddy wet hands on a bikeride, although i still wipe them slightly before using my phone.

No issues, make sure you scan all whole finger (circumfrence) as you go through the cycle, people scan the same angle over and over again

This is the key. Try as many different angles as you can when registering your finger.

Agree with this. Also did this when I registered my fingers. Scanner works well. One of the best out there.
I sort of like the idea of a press and scan. Would think if the scanner was active the whole time it would possibility affect battery life and keep the phone awake. Possibly a good design from Sony, especially with marshmallow coming with the doze feature.

Mine behave quite differently. I press the power button and then it just reads my fingerprint. It get it right just about every time, so it's like pressing like it is without the finger print scanner. I'm actually very impressed.

if you have free finger slot and want extra precision, you can scan the main finger you use twice , with as many angles as you can.
i'm very impressed by this sensor love it!
I have my Z5 for 5 days only. I registered 3 right hand fingers and one left, but I actually got only 50% success unlocking. I thought it's just a hardware limitation or something...
Then I read this thread and registeted my main finger twice, also applying the "cover as much around" (I'm one of those who thought I should be constant when registering my fingerprint).
Anyway, I wanted to thank you guys and to confirm - I get 100% reading success rate now, plus the power push+scanner unlocks 10 out of 10.
Amazing scanner!
PS: of course I have to try in different conditions too, fingers wet or greasy etc.

The fingerprint scanner is useless

Hey,
I have the Z5C now for over 3 months. The device is great but one thing is drivin' me nuts. The fingerprint scanner is just useless. It hardly works and when it works it's just slow.
I've tried everything scanning multiple fingerprints of the same finger, different locations and so on. But nothing helps.
Have you guys any tipson how to improve the fingerprint scanner?
I've found that I was not holding down my finger long enough. After I started holding it down a little longer, it seemed like it started working much better, nearly everytime.
I found that it sometimes doesnt work with smart lock. I'll try the fingerprint scanner many times and it will give me a failure, then I just swipe, and unlocks
Mine works just fine, as long I don't have really greasy fingers...
Working fine here as well. Sometimes it gets a bit greasy, clean it with a cloth and it works well again.
works fine for me too. Has trouble when my finger is wet, but probably any scanner would have this problem.
Working flawlessly here. It could be faster but at least it's consistent.
My only issue is also if my finger is wet. Otherwise, I have no problem with the fingerprint scanner. Works every time. Sometimes, too well. I've just picked up my phone, hit the scanner just right, and unlocked the phone without trying too.
No matter what I've tried I can't get it to consistently work. Washed the phone with soap. Cleaned the scanner with alcohol. It'll work for a little. Bit but then stop working. I must have more oily hands than most. But the scanner on the nexus 6p never failed me.
Wet or greasy fingers won't work... If the finger you programed into the phone isn't the same or similar state then it won't work..
I might program a wet or greasy finger as well So I get the same response when unlocking.. Watch this space.
Probably haven't helped washing the phone with soap XD... I'm getting vivid images of a glass of JD with a phone in it now....

Yeah that is exactly my problem. If my finger is slightly greasy it won't work. It's so annoying.
Pocketnow had the same problem with their Z5 aswell. My experience is preety much the same.
https://www.youtube.com/watch?v=pa7wT8DgLas
To anybody having problems with the scanner: is there a possibility that you have registered your fingerprints while your fingers were wet or greasy? (and now clean fingers are not properly recognized)
On another note, I noticed that the scanner only recognizes a certain portion of the finger and only in the correct orientation (even if I properly moved my finger during registration).
Mine is often too fast, unlocking the phone when I only wanted to check the time.
If my fingers are sweaty, it'll have issues, but that's to be expected.

That's exactly the issue. Some people just naturally have more oily hands, like myself. The fingerprint scanner should be good enough to account for that. This was never an issue when I used the iPhone 6s or when I used the Nexus 6P. I've only experienced a fingerprint scanner as incapable on the Z5C.
instead on focusing only on adding a fingerprint you should also note which type of grip you have when registering. Since the orientation of the fingerprint is recorded as well it seems. And finally add the same finger multiple times with a different grip and if you unlock using the same grip/finger combo as registered, i have had no issues.

Tried that as well. Most of the time I get "Finger moved too fast" or something. Or it's "Not recognized".

This is a great point; finger orientation matters, in my experience. I used to register my finger lined up with the sensor, but I got many unlock failures this way. Then I noticed that I would usually grab and turn on the phone with my finger at an angle. I retrained the sensor, moving my finger to the various orientations that I might use. This improved recognition greatly.
Remember also to vary your finger position slightly when you train, just like the phone asks you to do. There is little point of training it with the same 10 scans of your finger. The more views it has, the easier it can interpolate for recognition. (On the flip side, presenting it with 10 completely different scans would not work well either.)

Na, that doesn't work for me. Even if I try to register a new finger it often vibrates that it has registered my finger but the progress circle is not moving. So it's not reading it properly right at the beginning...
I've had no probems with the scanner- occasionally it takes more than one try but that's usually because of my finger/thumb position.
As above though I did make sure when I registered each figit that I moved it around to give the print in lots of different positions.
Fingerprint scanner works flawlessly for me I'm very impressed with it
Hi all,
For me it works well, i have some problems when my fingers are wet but it unlock the device faster than place a patern
In the other hand i try to use it with Paypal app but all the time it tells that fingerprint is not available, did you have the same problem with paypal app?
My bank app uses the fingerprint too and works like expected

Fingerprint scanner reliability

Hello! I have seen the ugly head come around that the scanner has not been super reliable. Now, I have the Tmo version and am on 9.0.0. Is that the reason currently? If not, It seems like the screen protector has smudges on it thus causing miss reads. If I try to wipe it off, it helps. Maybe we should be looking at a different screen protector? Thoughts?
Cheers
Joshua
I haven't had a fail to read yet... A few times it was slightly slower but still went through. Maybe try resetting up your finger. I know if my hands have been wet for a while my old phones wouldn't read.

I have reset it up a few times now. Tried even setting it up twice and that still didn't help much (to do this, I just kept pressing it again and again and it finally logged a second finger).

The more i use the FP reader, the better it seems to be getting. One thing is that it requires more pressure than my old Moto Z Play, but that's been an easy adjustment. Give it a little more time and continue to use all the fingers that you have stored. I mainly use my right thumb, and it works all the time now. My left thumb is hit and miss, so I'm using it more.
Unlocked the display 30+ times on 9.0.4 and it didn't reject my finger once. Speed varied each time if you place your finger/thumb perfectly aligned will unlock almost instantly
Was an OTA for screen unlock improvements already not sure what it changed though

Ill try pressing harder. Good idea!
I have the TMo version and I don't really get failures for my main/first finger entered. It seems that the more I use a particular finger, the better it unlocks. So the first finger is fine. The second was ok and is getting better. Third and fourth are still a mixed bag but getting better. My suggestion is to make sure you are enrolling them as you would be using them. So if you're going to be using a particular finger while cradling the phone a certain way, enroll it that way. If you will use that finger while the phone is sitting on your desk, enroll it that way. That seems to be the main thing I've found.
It seems the scanner isn't reliable on mine. It is really snappy after the initial setup. Then it loses accuracy within minutes after the setup. It doesn't recognize any of the finger 90% of the the time. I ended up either enter in the pin or use face detection. I don't understand the problem. my oneplus 6t is a tmobile.
I've got a McLaren on OS 9.0.9, and can definitely vouch for unlock instability w/ the left thumb.
Still have the screen protector on from factory shipment, so don't know if removing it would help, but not enough of a nuisance for me to want to remove it...yet.
I'm having an even worse issue.. A friend is able to unlock my phone without adding his fingerprint to my phone.. OP isn't taking this issue serious when I report this to them and they keep telling me to add my fingerprints again..
I have a OP 6T McLaren Edition, and just registered my right thumb. When I can't use my thumb, I use face recognition.
So far it's been reliable after a few weeks of use, but I've noticed you need to learn the right spot and the way you put the finger also influences its accuracy.
Something I've noticed...
I didn't use the "face unlock" when I first got the phone. Just used the fingerprint...VERY quick. Then, I turned on the face unlock just to see how well it worked, and was surprised how well it DID work (just not with sunglasses...duh). I've noticed, that if I wake up the phone,
with it anywhere near my face and try to unlock it with the fingerprint sensor (habit), the phone will stutter while I assume it is trying figure out WHICH way to unlock it.
Any chance that is the issue with yours?
If I have the phone laying on a table, no where near my face, and hit the power button, the fingerprint sensor is VERY responsive, but, if my face is anywhere near the phone, it struggles if I hit the fingerprint sensor.
Just throwing it out there...
Hmm.. I did notice that. I'll try disabling face unlock on my phone and observe it.

Fingerprint & Gloves

So I had blue latex gloves on this morning at my work and just tried unlocking my 6T T-mobile and Bang... Phone is unlocking even with the gloves on . Is it normal or a security flaw? Please comment.

I read that OnePlus fingerprint sensor "learn" with time. Maybe you just used it in some different conditions and it became "insensitive" to the fingerprint (example: if used too much with a dirty thumb, it can get used and unlock the phone even the fingerprint it's not perfect).
You could try to delete actual record of your fingerprint, use the phone for a day or two and try again with gloves.
It shouldn't unlock anymore.
That my hypothesis...
Let us know.
I haven't used blue latex gloves, but I've definitely been able to unlock my phone with translucent latex gloves on... Translucent enough to the point where a camera should not be able to get a discernable fingerprint pattern.
I tried with about 5 different glove varieties (latex, nitrile, clear polyethylene) and none of them would unlock the phone.
I've found the reader to be about as good as my 3T, and definitely better than my (work-provided) iPhone 6 (reader on this sucks). The one common use case where the 6T reader seems to fail is coming out of the shower drying off my hand, and trying to FP unlock. Doesn't work for me. Even if my hands are not wrinkly/pruney from being wet, it's a few minutes before they will work on the reader. My 3T was not so picky about this.
But generally I'm happy with the FP reader. It DEFINITELY learns over time. Initially my left thumbprint was hit or miss; now it almost always works.

fingerprint scanner works about 1 of every 5 times

Anyone else with a similar experience? That's going to make me turn it off... Or am I just doing something wrong?
The sensor isn't as big as the interface leads you to believe, try registering multiple fingerprints using the same finger. Make sure your getting the edges of your finger print too.
I'm getting it every time. Make sure you get every bit of what you'd hit the sensor with.

I'm struggling with mine too. I've done my prints a couple times and I still keep getting press harder or couldn't read. Idk if the manufacturing of these could be hit or miss.
cant even reg my thumb, not sure if my skin is too dry, my hands are a mess. back to face recog.
I took the advice and did my prints again.. (3rd time) I scanned them more to the way I angle my thumbs and fingers. I was more thorough with the scan and it's reading my prints more consistently. Thank goodness!
got the same problem here .... s10+ exynos Germany
So facial recognition is a lot quicker .... but with the missing iris scanner you`re not able to unlock your phone in the darkness anymore
I clearly face the same problem,
The captor is not verry accurate ... I'm a bit disapointed about it tbh. It was 50% of the reason why I changed, so I can use fp to unlock my phone again (at the back, next to cam is definitely not a good solution)

I'm having issues myself 1 out of 7 times, that update hasn't shown up for me, unlocked s10+
I actually followed the video on phonescoop.com about not following the instructions, as they are slightly misleading. It works better, but in general, I don't normally use screen protectors and I can definitely tell a difference, just using the phone. Also, make sure you have Touch Sensitivity turned on in display settings, which is supposed to increase the sensitivity with a screen protector.
Anyone try to use the fingerprint reader while it's plugged in and charging? Work ok?
I struggled at first. I went to software updates hoping to find one. Sure enough an update was there after I promoted it to search. It was better but still not 100%. Today however, I just realized it's been 100%. I attribute utter to me learning how to place my finger accurately. I think that's the biggest issue now. Is you need to just learn how it works.
Does anyone have an issue as the one in the screenshot
Like when trying to unlock using fingerprint we have the thumb impression over the ripple effect

Having no issues. Just did it.
Mine has failed to unlock with fingerprint a total of 1 time since I got it. Make sure to add the finger you plan on using twice and in the way that you will be comfortably using it usually. Also make sure to move your finger around when saving it, try to catch all the edges.

oh cool thanks for the info =)
The update I received yesterday was completely separate from the usual software update. It was a notification for update to just the biometrics after that it worked a lot better.
THere's something that you can do to make a massive improvement, after you get the software update that improves the fingerprint scanner. It worked for me.
Delete your fingerprints. Reboot into recovery, and delete the cache partition.
Then go back and add your fingerpritns again. Do it twice. Add two fingerprint profiles using the same finger.
For me, this changed it from being slow, and difficult to scan, to instant, and only needing to press my thumb very lightly.
