FP reader and LOSMicroG - OnePlus 7T Questions & Answers

Hi, I did a fresh install on my phone of the official LOSMicroG. I can set up finger prints, but when I attempt to use them to unlock the phone, or in biometric apps, it always fails as an unrecognized finger print. If anyone has any ideas, let me know?
Thanks

Fingerprint recording / storing issue

I am facing issues with the fingerprint scanner.
I am able to unlock the phone with the stored fingerprints.
However, I am unable to record new ones. I have not exhausted the fingerprints storage option and still have some left. Also, if I have my finger placed on the scanner while clicking on the 'add button', it briefly detects the fingerprint, but doesn't continue with completing the recording. It appears that it is not able to detect the fingerprint while in record mode, but it works fine for unlocking!
Any help would be greatly appreciated!

fingerprint not detecting sometimes

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.

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?

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

unable to add fingerprints (Galaxy A5 2017, Lineage OS 14.1 build 20180704)

Hi all,
i just flashed LOS on my phone. On first boot, I was able to save 4 fingerprints without any problems, and I can use those fingers to unlock the phone, so the fingerprint reader itself works. However, if I try to add more fingerprints in the settings, I get to the screen where it prompts me to put my finger on the sensor, but when I do, nothing happens. No vibration, no messages on screen, like it doesn't register the finger at all. Tried several fingers, rebooting the phone, with/without charger connected, nothing works. Any ideas?
Cheers, Ilinsekt

Question Fingerprint enrollment

Hello,
i am having very frustrating time trying to enroll a fingerprint on the phone. This is my first phone with in-screen fingerprint reader so i am not sure if this is the intented implementation. I want to enroll two fingerprints of the same finger (thumb) for better accuracy. Enrolling first fingerprint is no problem, but when i try to enroll the second one, halfway (sometimes sooner, sometimes later) trough the enrollment process i cant help but press with the part of the fingerprint which is already enrolled with fingerprint 1 and the enrollment progress is reset which means i have to start over. I also get the message that this fingerprint cannot be enrolled becauise it is already enrolled fith fingerprint 1. Of course, when i try to enroll once again, the exact same thing happens again and again to the point that is almost impossible to enroll two fingerprints of the same finger. So far I have been using xiaomi phones with physical fingerprint readers and enrolling two or more fingerprints of the same finger was no issue at all.
Can someone confirm whether this happens with in-screen fingerprint readers or is this an OP thing? Thanks.

you don't need to register your finger twice, once is enough
