fingerprint reader - OnePlus 7T Pro (Regular & McLaren) Q & A

Anyone else having fingerprint reader issues or tips?
I'm using screen protector that comes with it out of the box and on the android version that includes the September security patch.
Haven't tried face unlock as with the pop up camera that seems just weird

What do you mean by "issues"?

I seem to be having a hard time to get it to work every time. The thumbs seem to be the best. I just deleted and redid the setup on my 3 fingers I have set up...

Same here: regular 7T pro, 10.0.3 and with the screenprotector still on. I regularly see the fingerprint animation at least 3 times, sometimes it doesn't work at all. Very annoying because it unlocking the phone is now very slow.
It seems to help if you press hard first and then lift your finger.

The 7t Pro has a bit difficult to read a new fingerprint, but after a few successful readings the phone will learn the fingerprint better to finally get fast and accurate.

I have same problem. I must set fingerprint again then unlocking works normally for few days.

Am I the only one that finds it so annoying when it blinds you at night ?

Mine also got better it seems, meaning less not unlocks. It's just different than a button that I'm used to.
Regarding the light at night, I believe it needs it to read your fingerprint. You can disable the ring... Maybe that helps (if you can find out)

Elephone U-Pro Fingerprint Problem

The FP scanner on the U-Pro is the worst I have ever used on any phone. It's recognition is poor, it vibrates meaninglessly and it tells you fingerprint not recognised even when phone has unlocked. Am I the only one with this problem?
Add more fingerprints for one finger changing the position of the finger (is a bit redundant but I think you can understand what I'm trying to say) .
For me works fine
I can't say I've noticed the problems you are experiencing. The FP unlock works better on my U Pro than on my old Moto G4 Plus and P9000.
I just wish it wasn't on the back of the phone as it's a real pain when mounted in my car.
Elephone U-Pro fingerprint reader problem
I have had elephone s7, si and not this one. I fully agree with you. Trying to find a solution yet.
horrible sensor
I'm having this problem too, lousy response from the sensor. But the tip of registering the same finger multiple times really makes it better :good: . Still not ideal you still have to press really hard. Real bummer for this otherwise beautiful Elephone U Pro.

Fingerprint sensor stops working

sometimes the indisplay Fingerprint sensor stops working at all.
The display wont recognize any touch and stays black.
If i push the Power button it starts working again.
This happens sporadically, 1 -3x a day
Did anyone had the same Problem?
Any suggestions?
Thanks for reading....
No one?

I haven't seen this problem. I use face unlock along with it and it usually recognizes my face before I can even scan it.
When the screen is black, you can put your finger on the display and some glowing circle Appears. This does not appear to me at all. The screen just stays Black.
Thx for the information.

Maybe your fingerprints got erased somehow? Does your phone display a fingerpring icon on the screen a second after you turn the screen off?
Sent from my LYA-L29 using XDA Labs
Yes the second I turn if off it shows a fingerprint sensor. Just after a while it won't toggle the sensor if I touch the display. It's like the fingerprint sensor is deactivated. The second I turn the display on manually it appears again.
Hello! I've got the p20 pro and now I'm testing mate 20 pro. Sometimes I'm not able to unlock the mate with my fingerprints at all. Same finger. The p20 works perfect, just touch and unlock. Mate sometimes I have to touch it 3-4 times before it unlocks , sometimes it doesn't unlock at all? Is that normal? The display was exchanged already because of this issue.
I believe you guys are not the only one. This on screen finger print is not reliable. I guess because they are new and will improve over time. Personally I just use face recognition than finger print. They are a lot more faster and accurate to unlock.
I know it's an old thread but it's happening to my M20Pro right now! It's awful! The screen is protected by a tempered glass made by Spigen (maybe this glass has issues?). I reconfigured the fingerprint and I touched almost 50 times until the phone captured the fingerprint! What's wrong with that sensor?!
I had problems with glass protector, if you can get plastic film it is fine, glass you will have problems....this was my finding
Possible brightness/proximity sensor issue

If you still have this phone and problem: I have a P30 Pro, and/but the reason I write here is because our phones share the fingerprint technology, and I didn't find anyone mentioning this problem regarding P30 Pro. So:
I have the same problem - seemingly sporadically the fingerprint sensor (or screen) wont react until I press the power button. Then I noticed that when the brightness/proximity sensor (located near the top right on the P30 Pro, and next (right) to the upper speaker on Mate 20 Pro) was covered, the screen would get unresponsive. I guess this is by design, to not accidently let your phone come to life in your pocket. The problem was/is that the proximity (?) sensor is way too sensitive - any obstruction at about 2 cm (0.8") above the sensor(s) will trigger this behaviour. I also think it can be triggered under other circumstances; I had som weird fingerprint/screen behaviour in a store with a high and very dark ceiling, but I have to test this again, so don't take my word for it.
Anyway - if anyone is having sporadic problems - see if this could be a reason.
Edit: Well, sometimes my screen is just totally unresponsive even without sensors blocked, so ... I noticed it a couple of times after digging my phone out of my pocket, suggesting it could still have something to do with the sensors turning the screen (functions) off. I'll try to see if I can make it behave the same way in other scenarios.
I have also been experiencing similar problems on my mate 20 pro, But mine is more of an accuracy problem. sometimes its on point and registers instantly. and other times it just doesnt at all.
However i have noticed that in extremely bright weather i have more issues, fingerprint doesnt read at all, and face ID is also doesn't. My finger print issues have started only after EMUI 10.1, so i suspect that it could possibly be a software related issue

Fingerprint speed & accuracy in 9.1

Has anyone noticed a change in fingerprint speed and accuracy since updating to EMUI 9.1?
The one thing that consistently annoys me about this phone is that the fingerprint reader is quite "picky", only choosing to work for me roughly 75% of the time (I use faceunlock for most things). Some people have said they have noticed an improvement in 9.1, so is this the general feeling or not?
(I'm asking as my Mate 20 Pro is no longer my main device, so it's now not getting used as much as it otherwise would)
Face unlock is the same, still very good. And fingerprint is a little bit faster, but above all it's more reliable now. I've had fewer mismatches since 9.1
I notice fingerprint unlock to be a little faster too, not as fast as the P30 scanner but faster than before. I don't really use it though because face unlock is so ridiculously fast. I just lift my phone off the table and less than a second later it's on the home screen without having to press or swipe anything.
Yeah, as I said, I use faceunlock too; but banking apps etc. all require fingerprint authentication, and that's when it tends not to work... (or at least has done in the past)
That's the 1st thing I noticed after the update to 9.1, fingerprint reader and face unlock much better. These where my biggest frustrations with my phone before the update...

Fingerprint sensor issues.

My fingerprint NEVER works on the first try. Sometime the 2nd and 3rd as well. I've registered both my pointer fingers TWICE each. I have had numerous Android devices including the G7 Power and never had this issue before. Anyone else having the same problem?
I've had the g7 optimo and now the g power 2020. Both have the fastest responding fingerprint sensors I've used. Sounds like you might have a hardware issue.
Yep!! Came from a G7, worked every single time. Now with the G it's hit and miss but only when opening the phone, haven't noticed it having issues with other apps.
What I've found to work out great, I use either pointer finger to unlock, more the right than left. So what I do is scan the right finger 3 times, and the left 2. That way each reading gets a different part of the finger and has a better chance at reading it. Hope that helps
Btw, I've done it on all my devices that have a fingerprint and it's always worked
It's my slowest smartphone talking about of fingerprint, and yes, you need to register your fingerprint very, but very accurately if you want a better unlock response. I needed to delete my fingerprints twice and then I did it again but without back protector and cleaning throughly my fingers, now the unlock accuracy it's better and don't need to try two or three times, but the time till the phone it's completely unlocked it's toooo long.
I would say to set up the fingerprints again. And pay close attention to scanning your entire fingertip slowly.
I have issues if my fingers get a little wet, like from condensation from a glass, or sweaty.

30 second fingerprint sensor fix

I've had S10, two S20's and now S21. They all have one thing in common... The fingerprint sensor does not work. I would guess my fingerprint success rate at about 20% accuracy. My S21 fingerprint sensor fails the first time every time. No matter how many times I re-enter my fingerprints. I thought the new fingerprint sensor in the S21 would be better, it isn't.
By accident, reading Flipboard, somebody posted a story on how to speed up android phones. I did what the article recommended. My phone did indeed seem faster, but there was an additional benefit, my fingerprint sensor went from 20% accuracy to well over 90%. Works almost every single time now.
Make sure developer mode is enabled (go to settings > about phone > tap build number a few times).
Go back to settings, at the bottom will be developer options > drawing section.
Three entries;
Window Animation Scale
Transition Animation Scale
Animator Duration Scale
All settings are default 1x.
Change all three settings to either .5x or zero.
Enjoy!
Sorry, but this solution doesn't make any sense.
Fingerprint on my S21 works great. Since dy one

Oh, I guess that means mine works great too. And, nobody else has ever had a problem with the Samsung fingerprint sensor. Got it.
I mean, the animation scale has nothing to do with the fingerprint sensor. So it's not that his works great and yours doesn't, but it's like saying you can fix your car's engine if you just eat 3 extra apples per day. Nothing to do with one another.
What exactly is the reasoning behind how this helps the fingerprint sensor? and what exactly is it doing? Are there any downsides to this?
Like I was saying, I changed the settings just out of curiosity because the originator of the article mentioned that the changes make your phone appear to run faster. Nothing was mentioned about the fingerprint sensor. But, after making the changes, I immediately noticed that my fingerprint sensor started working. It was very dramatic as my sensor would fail the first time every time, and maybe 50% of the time on the second attempt. It was not unusual for me to have 5 failures in a row, locking the sensor for 30 seconds, multiple times a week.
My sister has a N20 Ultra and her sensor was so bad she quit using it. I contacted her about changing those settings, which she did, and her sensor started working too. This isn't my first rodeo, I've had a history with Samsung and their under display sensors. Mine has never worked going back to the S10.
I can't explain why changing these settings affect the sensor, but they do. I just changed back to 1x and my fingerprint sensor started failing just like it always has. Changed back to .5x and it starts working again. Sometimes I get the sense my sensor is not actually attempting to read fingerprint, just fails repeatedly. My guess is because the screen draws animations faster, the fingerprint sensor animation is faster too. Maybe that has something to do with it? So, analogy of car engine and apples isn't applicable. There might actually be some connection here.
Bottom line, it takes 30 seconds to change settings so you can easily do it and revert back just as quick. There seems to be nothing to lose, so...
I've noticed a substantial decrease in battery life with the changes from 1x to .5x. I reverted back to 1x and redid my fingerprints, once focusing on the center of the sensor and then a 2nd entry for the same finger focusing on the edges of the sensor. I'm going to have to live with this until the next non-Samsung phone comes along that I want to try...
Animation sucks up cpu, which slows down fingerprint.
No animation is best, what do I need fancy effects to tell me what I'm already doing lol
This entire thread reads like an April Fools joke.
This is the first time I am using on screen fingerprint reader. Absolutely hated it. However, over the days I have developed muscle memory and my finger goes to the correct spot. My accuracy went from 40 to 90% in the last month or so.
There are few things that can be done to improve finger print reader
- Use both the thumbs in one fingerprint
- Scanning along the edges of the scanner location.
THere are you tube videos that explain this in detail.
Additinal tip. I have enabled lift to wake and faceunlock as well. This has helped me faster unlock pretty much every time i pick up the phone.
PS: To me on the screen reader is more of a gimmick, it will take a few more generations to get this working very well for everyone.
There is space near the camera on the back where samsung could have place the reader.
This will give you additonal finger gesture features. Like in note 9 you can pull down and push up the norification bar and so on. ANyways this is a lost cause.

Don't do this. Scan each thumb twice, and it will work better. I usually do my right thumb 3x, my left thumb once, and my pointer finger once. Works perfectly for me, I'd say 99.9% of the time.

Oh wow, how did you manage to register 5 fingerprints? I can only register a maximum of 4.

Sorry, I have a **** ton of phones laying around. Some let you scan 5 times, others 4.

I HATE animations. They were cute maybe the first two times but after that I was done with them. And having to enable dev options is stupid. I use several apps that either complain about dev options being enabled or just plain won't run at all. No animations should be a normal selectable item like wallpaper.

To be honest, I thought I was the only one who truly hated animations. These seem extremely unnecessary and a little bit tacky.

Same here, I actually thought it was impossible to register 5 fingerprints, considering that I’ve been only able to do 3 or 4 max.
