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!
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?

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

Hello,
I have an unlocked HTC 10 and have noticed over the past few months that on occasion, the password protection is turned off. I have a password set up as well as the fingerprint reader and both work well. But every so often, I'll notice that the lock key is unlocked on the lock screen and I can swipe up without having to use my fingerprint or type in a password. This is not secure and is a glitch that needs to be fixed. I checked through all of my security settings and cannot find anything that could be causing the issue. Smart Lock is only enabled for my car and my home. I notice this unlocked lock screen when I'm at work so it's not related to that. Trusted voice, face, and on-body detection are all off. The only way I can get the phone to be locked again and require my fingerprint or password is to restart the device. The issue still persists with the new Android 7.0 update as well.
Anyone else notice this issue? Any suggestions?
Thank you
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
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
