Fingerprint Sensor issue

Loving my Zuk, or was. I set up the screen lock for fingerprint sensor and it was working great. Recognises my thumb first time every time. Now though I can unlock with just a normal swipe. It doesn't even demand the backup pin number. I went back into settings and it still had the fingerprint setup as the screen lock so I removed it and set it up again and hey presto i was back in action but only for about 10 minutes and it went back to no security at all.
There were 4 small OTA updates today so I am guessing one of these has messed it up. Each update didn't say what it was for
Has anybody else had this issue?

Is working well for me.
Have you added other smartlock event (wifi, location, ecc) that can interfere with the lockscreen and disable it?

My MOTO 360 is in smartlock as a trusted device, don't fully understand what smartlock is to be honest. If I remove it would it affect anything?

Of course!
I have also a smartwatch (LG Urbane) and the watch as a trusted device. When the smartwatch is connected to the phone the lockscreen is always DEACTIVE, even if you have configured a lock screen (PIN, pattern and or fingerprint)
Power off your watch (or set if in airplane mode) to check if lockscreen turns on in the phone

I have just removed my 360 as a trusted device and the screen lock now works perfectly and so I now understand how this works. Many thanks for the advice. I can now stop worrying that I have a faulty device!

I am facing as well to a lockscreen and fingerprint issue.
I used fingerprint to open lockscreen and pattern as secondary. After showing the ZUK to somebody I needed to modify the pattern. From that time I am unable to switch back to fingerprint. Only three opportunities what I have, and no swipe or fingerprint, due to "Disabled by administrator, encryption policy or credential storage". What accessibility service messes up the fingerprint usage? Do you guys have an idea? All of them are swiched off.

My problem is solved. I needed to delete credentials in security settings.

Hi. I'm having some problems with the fingerprint sensor. Is working intermitent or not. I've asked zuk support already but no answer yet. I don't know if it's a software issue or hardware. It's any way to calibrate the sensor? Maybe it's decalibrated? Any help will be usefull. Thank you.
LE I already made a factory reset. No improvement.

I'm using the Zuk since a month, and no problems with the fingerprint at all.
In any occasions, the fingerprint sensor don't detects the finger the first time but at second try.
Since a few days, I'm on CyanogenMod (instead of Cyanogen OS) and I think the sensor is less responsive (sometimes I need to try three times or use the lock pattern).
But if you are with issues using CyanogenOS I think is due to a hardware issue.

Fingerprint actions has been removed by CM a few OTA updates ago.
I hope a kernel developer will add soon, but ZUK has not too much developers

Modded kernel for COS can be found in the other topic about this issue.
The OnePlus 2 sources happen to have a compatible finger print driver with capacitive button support which is currently being checked out for porting to the Chroma kernel.
So don't fret.. The feature can be restored.

iam not able to use my fingerprint lock, it was working well before but now suddenly it is not showing the option in CHOSE LOCK SCREEN- the SWIPE an d FINGER PRINT OPTION IS DISABLED.
how to enable it

Thanks ... I had the same issue & delete credentials in security settings.

I bought zuk z1 3days ago
Why We cannot use fingerprint sensor to lock and unlock the device for both purposes

Having an issue with the fingerprint sensor.....
Works fine but when push notifications(any notifications**) show up on the lock screen ..the sensor gets non responsive...mind u almost impossible to unlock
Have no choice other than security pin
And I Definitely think this is result of All IN ONE Issue
Say like.....1)fingerprint sensor integrated into hone Button, 2)Faulty software patching, 3) Me, adding two or more fingerprints
Any Suggestions from u guys Feels helpful
BTW....Bought the product via Amazon.in

Is there a provision in the ZUK Z1 which let's you interact with the device by simply tapping on the fingerprint sensor except on the lock screen?
If the device is locked and the screen is off too, simply placing my hand on the fingerprint sensor doesn't work. I always have to press on the button to wake the screen first.
Any help?

May sb tell me the modell of the finger print reader of the ZUK Z1? Pls. use AIDA64.

That's part the of custom roms. Fingerprint as home button can be activated by flashing something, you need root. But in the play store you can try https://play.google.com/store/apps/details?id=com.ztc1997.fingerprint2sleep
But it's not that what you need. Without root and a kernel where its implemented its not possible.

Hey my fingerprint was working fine till one day it just started vibrating when I tried to scan it. I tried deleting the saved fingerprints and registered new. I'm not even Able to register new fingerprints. What do I do?

Le max 2 finger print

My fingerprint sensor doesn't seem to be working as when I add a fingerprint it occasionally says 'try againe' at the top of the screen and then won't register my finger print. If it does not do that then it retest eras my finger all the way till the last part and then don't respond or vibrate. How can I solve this issue?

I have the same issue.

Looks like I have the same issue as reported by my wife (I'm currently not in possession of the unit as I'm abroad and it has arrived few days back). She knows how to register as I have the Letv 1s and she was playing with it before.
The symptoms are as you say, no vibration and no detection of the fingerprint.
Can it be from the rom that came with the phone (maybe multilanguage). I can't remember if on 1s I had this problem.
Currently I have emailed the shop and I'm waiting for their reply. If you guys find a fix, please share.

Hi,
For me, the fingerprint scanner is the real weak point of this phone.
If it would have a better one, it would be flawless... except for the lack of development due to LeEco not publishing open source for their devices
And trust me : I've had the OP3 for several days before getting the LeEco. And that fingerprint scanner works as it should and in a blink of an eye you can use your phone !
What I found out is that this fingerprintscanner is really sssslllllooooowwwww....
So press it once, and then put your finger back on for several seconds.
But of course, doing so reduces the nice thing in having a fingerprint scanner as you're done quicker with "screen on" + "pattern/code"...
Really hope that LeEco can improve this... but when I see how they act on their own forums (a representative posts about every 20 days) I am not that optimistic

For me the fingerprint Scanner is working perfectly. Faster than iPhone 6 und it only fails to read 1 out of 15. Got 3 prints registered and it does very well

What version of the software are you using?

The fingerprint sensor has gotta be the worst ever in a mobile device. My phone takes good 5 seconds to unlock. Registering new fingerprints takes ages. Last I heard that this was some qualcomm tech which does scanning of skin layers under the top layer. But right now the technology is big fail.
That fingerprint sensor hardware is beta 1 in our phone. I am sure the new Le Max 3 which is coming out with Snapdragon 823 will not have this issue. They will advertise how the fingerprint is now 100x faster than before and bla bla.

I am on TeamSpains Cm13 Version. In eui it wasnt that good but now its working without any problems
And to the guy over this post:. 5 seconds for fingerprint unlock? May be your device is faulty. I didnt experience this. Even not on stockrom

Even my device on 15S unlockes after 5 seconds. The worst sensor and algorithm ever.

Hello guys,
One way to make finger print recognition better : save several time the same finger print.
Not very sexy but it works for me

So as I have arrived home, I've changed the firmware to 015s stock and the fingerprint started to work. Of course it's not ideal as my 1s but at least it's working. It takes about a second to read and unlock... acceptable to be honest. Maybe they will improve with the upgrades because for 1s it had improved within 2-3 firmwares to super fast recognition.

My experiences after several ROM, the international Indian ROM has removed bug.
Recognition really fast, from 10 attempts 8 immediately.
Note!
By the installation Rome should be installed super su with.
The encoding is prevented with it.

i have the same experience here... got my max2 from geekbuying but wont even recognize my fingerprints... so i updated to 5.8 eui from india not the Chinese version and not it works... however it takes one sec to open slower than my honor 5x. ... hope leeco would make it a bit faster considering the new tech it has...

Is there a major difference between the indian rom and the stock chinese rom that has english language? Does the indian rom have english language selection?

Yes the system language is complete into English.

The fingerprint scanner on 5.8.16s is much improved It seems much faster now. There was even an upgrade notice at first boot where it said it would erase my previous prints to upgrade.

Thanks for the update, will try it.

Nougat fingerprint delay

I just updated to Nougat and after a few hours my fingerprint scanner starts acting really weird. Sometimes it picks up my finger but takes a few seconds to unlock and other times it just doesn't work (no haptic feed back at all). A reboot fixes it for a bit but it eventually starts acting up again. Anyone else experiencing this? I have seen similar issues in the past on MM but never had this problem until today. Also didn't find any fixes (besides other people saying to reboot).

+1 for the delayed unlock. You're not alone. Many others have reported the same problem post Nougat update.

You're not alone. I observed delays as well, especially after the Nougat update

I haven't noticed a change, but have read that if you change the following it should improve
Settings>Developer Options>Animator Duration Scale = .5x
My fingerprint scanner is almost instant.

You can also try installing Ninja kernel. The fingerprint scanner works using the big cluster instead of the little like the stock kernel. My fingerprint scanner is almost instant with this setup.

Problem with the fingerprint recognition

Hello all.
I have a problem with the fingerprint recognition.
I have an s7 edge with the exynos cpu and with the latest official rom.
When I first set the fingerprints up, they work flawlessly for about a month. After the first month, the recognition of my fingerprints starts getting worse and worse and it ends up all most not recognizing them at all. (Success rate of 1/20 or worse).
I delete all of the fingerprints and set them up again from scratch. I even try to put my finger in different ways and positions on the sensor but the problem persists. The first month everything works great and then chaos.
The only thing I haven't tried yet is factory defaults because setting everything up on the phone again is a pita.
Any suggestions?

If setting fingerprints from scratch helps and they are recognised at first, think about your fingers. Maybe due to the nature of your daily job, your finger skin changes, making it difficult to recognised after so long.

i've had the same issue on stock rom, so maybe try custom? for me stock wasnt unblocking too often with finger, so after going to custom I was surprised by how well it works

Fingerprint issue

I am using Max pro m1 since 1 month and I face this issue where the fingerprint doesn't respond at all , It's doesn't even vibrate to acknowledge the failed recognition , I need to tap twice or more for it to know that I place a finger on the sensor and then it recognises.
I am on the latest build to date
1805.316 -> released on 12 July 2018

Known issue. Try tapping it with a slightly more force on the first try itself instead of just touching it lightly.
You will then get used to it after a few times.

Ya , that's working.
Is it due to a cheap sensor , or software stuggling to render accuracy?
Thanks for the reply mate !

Asus zenfone max pro m1 Fingerprint Sensor Issue Solved
The issue is happened to me. Like in this issue i can't be able to use fingerprint sensor and do all the stuff to get rid of this. I even deleted all the fingerprint and after this i can't be able to add new fingerprint. But know from this trick i applied it's all solved. It's that you just have to restart your device and it all works fine. Yaa seriously.. Thankyou..

Yeah i too faced the issue. On day 1 itself after sometime my fingerprint sensor was not at all responding. I had to manually enter password to unlock. I deleted all my fingerprints. Restarted and added newly. Now Day 3 so far no problem with unlocking.

Me also faced this problem in 6gb 318 firmware
After restart working fine.
