I stumble upon a semi-interesting thing when I was about to set up the fingerprint reader.
I always register the same finger 2-3 times to increase accuracy.
When I performed the process in my new Edge+ I saw that every time I logged in with an already enrolled finger to the menu for fingerprints, the phone highlighted one of the already enrolled prints thus gave an indication of which of the already enrolled prints that it matched my print to.
Difficult to explain, I´ll attach a few prints but thinking it could be helpful if you want to increase accuracy and want to update an already enrolled print that´s not accurate.

I read this a few times and I really can't reproduce what you are trying to explain. The image links you have provided don't help at all, sorry.

it recognises that you have already input that finger that's why it's so accurate it won't do it with a different finger

What he's trying to say is, when you go to the Settings where you enroll your fingerprints, if all of your fingerprints (out of 4) are already enrolled, when you press your finger to the home button, the menu highlights which finger (out of 4 enrollment) just touched the home button. So what he is saying is, we can use this feature to see if the fingerprint has been registered correctly or not and hence we can enroll same finger from different angles in multiple enrollment slots so that it enhances the detection process for one finger.
Frankly, I think the fingerprint sensor is already very quick and precise. Also, its wiser to register the fingerprint from different angle while enrolling one finger is much better than enrolling same fingerprint in multiple slots.
Nice tip op. Would never think to check it that way, but it is a good way to check if your noticing that it's often hard to unlike your phone with your finger print.

OP3 finger print is really fast but sometimes I just can't it to get it work, once it doesn't work it'll not work at all and then I have to unlock using Pattern
Does anyone have this issue?
I found that if on lockscreen there is a lock symbol it won't open by fingerprint. If there is a fingerprint symbol then it works
Not to worry!! While you are registering a finger..... u have to completely register each corner of the finger print.....only then it works from however u put ur finger on it!! I experienced it many times too!!!
Just registry 1 finger 2 times...thats all
But it works always except when there's a lock icon on lock screen.
If there's a fingerprint scanner symbol it works 100%
it wont work with wet finger, wipe your hand
When you register a finger, you have to put all kinds of different parts of the fingertip on different parts of the fingerprint scanner, so that the scanner "knows" your finger in all possible positions. That is what the lenghty procedure is for.
Yeah I've done all kinds of way, rolled it, left, right, top, down.
Does anyone know why there's a lock symbol sometimes on lock screen instead of fingerprint symbol

Fingerprint Problem May Be?
Hi,
Sometimes my fingerprint is not recognized by fingerprint scanner. I have registered two fingerprints for the same finger. Still sometimes it does not recognize.
Is it because still some area is left which is not recognized? When it is not recognized and i put my center of finger on scanner, it recognizes.
Is it fine? Also is it fine if it doesn't recognizes if only a part of sensor is touched by finger. I am using fingerprint sensor first time so little bit skeptical.
I think i am testing it too much just to confirm if it is fine and somehow able to make it fail at some area of my finger. :silly:
Please help.
Please help me guys.

Obviously, my hand are clean and i am testing with clean hands
It requires pin after a reboot, then you should be able to use the fingerprint reader until the next reboot.

Its because of security or you can use require pin on boot and it will take bit long for booting
But what about the lock symbol and finger print symbol on the lockscreen, has no one observed this yet?
I'm unable to attach pictures as in XDA website to attach images it is asking me url

Been using OP3 FP scanner from last one week. I have 4 Fingers registered it works without any problem. Clean you FPS
I've been having an issue where I would take the phone out of my pocket and the fingerprint scanner wouldn't even vibrate when I touched it. After trying several settings I started putting my phone in my pocket with the screen facing out instead of towards my leg. I think the fingerprint scanner would get activated while rubbing up against my thigh. So far I can tell it's working fine. Everytime I take it out of my pocket it recognizes my finger right away. Also I noticed less battery drain.

I saw it. Often when i unlock using fingerprint the phone gets locked automatically 1 second after unlocking, than the symbol is a lock and i have to use the pattern. Then there is a text something like "For improvement of safety, a pattern is required" really annoying

Thank God, I was starting to wonder if it's only in my phone. I think doze maybe doing this. Is there any way to contact oneplus team on this.?
I started a chat yesterday but the girl with even worse english than mine told me to do a hard reset and wipe everything. Havnt done it cause i dont think it will help
Is there a way to use the fingerprint sensor to unlock the phone, but not having to keep the finger print stored? Several people use my phone, and I never keep my phone locked because there's nothing secret on there. I find it very useful to use the fingerprint sensor as its int a natural spot when you pick the phone up. But i hate having the phone locked I've tried double tap to wake before and it's always been very spotty. I would like to save my hardware buttons.
No, sorry.

You can have several different user account..
Exactly how many use your phone? Why not store a fingerprint for each one of those users.
Couldn't you just make your screen lock a swipe? Or none? It doesn't use the fingerprint sensor, but it achieves your goal.
Hi there
I just switched from a Asus Zenfone 5z which has a dedicated fingerprint sensor. So one touch and you ard on home screen.
Now the fingerprint sensor on Note 10 + is slow, also the fact that one has to first click the side key and then put the finger on the screen and seemingly wait for 2 sec.
It is nowhere near as fast as the zenfone 5z.
Have you guys got any better solution or idea to unlock it fast.
Thank you for your time.

You don't exactly have to turn on phone to use fingerprint reader.
If you know the position of fingerprint reader then putting your finger there would turn on and unlock phone. But that would be if you can get it on right position. If not it would tell you and then you can readjust as it will then show you.
Other option would be to have always on display and would show position of fingerprint reader.
You can also double tap to wake up phone as well. Then go through same process.
Hope some others could add more but these has been what I've found out with my usage.

Enable the gesture "lift to wake"
Enable "always on display" so that you always see the finger print location.
What ever finger you use most for the finger print, scan it for 2 spots out of the 4 available. So I have my left thumb for 1, right pointer for 2, and right Thumb for 3 and 4. My right thumb is now always solidly fast.

1. Please clarify : Do you mean to register the same right thumb twice to increase accuracy of the right thumb, as that is what I mostly use.
2. Currently always on display is set as tap to show.
Does making it always show have any significant reduction in battery.
And that you for your time, you are very helpfull.

Didn't even know that I had to just press the locked screen.
Also thank you for recommending the lift to wake up gesture, has increased the speed a lot.
Still wondering if I can use NFC to keep it unlocked as it is always kept on a phone stand.
Many thanks for your time.

You can use Smart lock Trusted places under settings-lock screen to keep phone unlocked. You just have to turn on phone then just swipe to go into phone without password but it will lock after a certain timeframe if not used.

I do know about Smart Lock but prefer not to use it as keeping the GPS on does feed the location data to other apps as well, not something I prefer to give away.
Thank you for the recommendation though.
You can register your face as well. It works really fast with lift to wake up gesture.
Smart lock can be used without GPS on, it uses a trusted wifi network to keep the phone unlocked or, if you have one a bluetooth speaker...
Don't need GPS at all...
Another vote for smart lock but with a wearable like a wear os watch. I pretty much never have to unlock my phone.
In case helpful to someone else, I enabled the increase touch sensitivity setting under Display settings and the fingerprint seems to work much quicker as I don't have to press down harder.

#1 YES
#2 It's a 4300mah battery, the AOD doesn't even dent it.
Happy to help!
I have AOD set to always on, and it is super easy to unlock.
I pick up the phone, hold my thumb on the sensor and it is unlocked instantly. I don't see how it could get any better than that!

Hi, I did turn it on after reading your post, enabled my location with GPS off and wifi connected but it doesn't work.
Is there anything special I need to do in this regard.
Thanks

Yes I turned ut on as well as the phone comes with a factory applied screen protector and that is what that setting seems to be for. Should have been on by default.
So last night I rebooted my phone and found that my fingerprint scanner isn't scanning my finger.
When my screen is locked, the fingerprint scanner doesn't work, it just doesn't respond (it's not consistent, when I use different lock methods (power button method, root method, accessebility method, Xposed method) it works one time and then again stops working)
There are 3 options of what happens:
I turn off the screen and put my finger on the scanner
1) the device unlocks
2) the device screen turns on and shows me the screen as if I pressed the home or power button
3) I get no response (this seems to be happening if I pressed the power button when the device is already locked)
1 and 2 are not always consistent, and I haven't pin pointed what the cause is
If 1) happens, then of course it works as expected and it will vibrate if it's the wrong finger, and unlock if it's correct
If 2) happens, it's the same as 1) just the device doesn't unlock, but just the screen turns on
If 3) happens, then it doesn't matter which finger, there is no response
I tried safe mode, it still didn't work.
I tried magisk core mode, also didn't help.
I saw someone wrote that it might be because of the dinner print gestures, but I don't use them, so I tried to activate them and they fully work even when the scanner isn't scanning my finger...
The scanner itself works, any app that I can use biometrics would recognize my finger...
And I know my fingers are still recognized, I made sure to check in settings... I even removed all my registered fingers and put in new ones, I rebooted between each step to see if it helps...
I have no idea what caused this problem, if any one knows please help.
My phone's situation is SM-G9600,
Magisk, EdXposed (obviously I tried the scanner after disabling both by putting magisk in core mode)
Android patch level from 1 September 2019
If this helps- build number: PPR1.180610.011.G9600ZHU5CSI2
I'll be happy to provide any information that might be helpful
The S9 has a common problem where the fingerprint scanner becomes unreliable even if there's a small scratch on it. Could you upload a photo of the back of your phone?
Here are some pictures taken with the phone through a mirror, no scratches on the sensor... Also it works in other situations, like anything that has somthing to do with fingerprint other then the screen lock.
I checked the the logs and I have some strange things there, for some reason the device is turning the fingerprint scanner off as if I don't have any registered prints... I also asked a friend to send me his logs, and the look like what one would expect, I'll attach the screenshots of both logs
