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?

Much worse fingerprint scanner responsiveness after update?

Ok, I'm struggling with this for days and it drives me crazy. After updating to APD1 my fingerprint scanner is much worse and the responsiveness sucks. It used to work well and usually it unlocked the phone on the first try. But I think because of the update it stopped working flawlessly. It doesn't read my finger so well sometimes I need to try few times to unlock the phone. There is also a block for few seconds after the fingerprint is wrongly read. I didn't have this earlier. When I tried to update my fingerprint in settings, the procedure change and now you need to read the fingerprint and take few seconds and repeat. It takes ages to add new finger.
Am I the only one with this problem? I have about 100mails with photos from cerberus because of wrongly read fingerprint.
Or maybe my scanner is broke?

Agreed I have also noticed same issue thought it was just me tho

No problem with mine. It works just as well before the update and I'm on APD1 as well.

No problem with mine as well.

No problem here either after updating to APD1. Same as before. Maybe you should wipe all your fingerprint and record it again.

My wifes s7 is having a problem and she locks herself out alot. My s7e is working amazing. Maybe one fail a day but its my error not the phone.
tapped on #datbombv7EchoRom

it only looks like yours mine is fien too

Screen rotation lock doesn't work on MI A1

After I rotate the phone and then toggle OFF the rotation button , the screen automatically rotate back to normal position, instead of remaining locked in horizontal position, and yes- I keep the phone physically rotated on its side the entire time
The phone is rooted with magisk, if it matters
What could cause this problem? I already tried to reset and disable developer options, which btw, would it make an issue booting the device if OEM unlocking won't be ON ?
-to make it clear - the screen rotation functions well when rotation mode is on, I just can't keep it in horizontal position
Thanks in advance

That's not a common error.
On both mine and my GF's A1 that setting works.
EDIT:
I just can't keep it in horizontal position

That's correct: You can't 'lock' screen to horisontal position!
Both untouched Android 8.0.0 April patch.

I thought this was normal behaviour for stock android? I understood only certain manufacturers allowed rotation lock in their ROM's like LG?
FYI: My stock A1 on April 8.0 returns to Portrait when rotation is turned off.

That's not an error. It's just how Android is designed to be.

On other android phones it's not the case, you can lock it on Samsung S8(oreo), Samsung S1 (stock) and on S1 with CM mod
Perhaps it was possible with the MI A1 before some of the latest updates too,I'm don't really remember, anyway, Xiaomi should return this function because it's useful and already exists in older and newer android phones WITH stock versions

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.

Moto G5 plus: Navbar not accepting touch, even woth one nav button feature.

Hi,
I've a moto g5 plus which is not accepting any touch to the navbar area. Even when I enable the one nav button feature, the navbar keys hide but I cannot touch or register response to that. I don't think it's a hardware issue but if it is, how should I check it?! I'm currently using fluid navbar guesture app to navigate.?
The problem appeared suddenly when I was on Android 7.0, I thought ota will fix this problem. So I updated device to 8.1. But problem did not solved. So I tried hard reset, but no luck. If somebody know what exactly the problem is, I'd be glad. The device is not rooted nor the bootloader is unlocked.
How do I install stock oreo rom? I think this should fix it but I'm not sure.
Please help.

If you have your warranty you should get the device checked, that sounds hardware unless you rooted (you didn't) and touched something
What was the last thing you remember doing before this trouble started?
Does the screen touch works at the bottom? Does the navbar register the touch but it doesn't do anything? Can you see your lockscreen?

Hi M1810, thanks for replying.
I've been told it's hardware issue by service centre but they not even touched my phone, that's another story perhaps. I don't think it's a hardware issue as I'm doubtful about how only the navbar portion of my screen became unresponsive only and not other part of screen?!!!
Last thing I remember doing is switching between one nav guesture feature toggling on and back. But it was working fine then for some time. It just suddenly stopped working. (This is the reason I think this is a software issue. With the moto nav bar feature.)
I've enabled the show touches from developer option. The taps not even getting registered on the bottom portion. Other than that, there is no problem. I can see lock screen but cannot touch the bottom three icons, the camera and google mic thing.

If not even the lockscreen lower part reponds then it's hardware.. if updating/reseting did not solve it

I don't know for sure, i recommend you to ask in that thread, ehat i know is that it is not recommended to install custom ROM's if you're currently on 8.1 stock
