When my device is fingerprint-locked and I use the camera from the lockscreen, if I swipe left my gallery is protected because the phone is still locked.
But when I do that, I can't unlock my Zuk using my fingerprint because it suddenly becomes not recognizable; I must use PIN.
Is it just me? It happens with both S3OH and S60J builds!
Nevermind, I just found the issue is gone in S60J.

I had this happen on my for stock android 2.3.3.. hope some devs or ppl can really help me out...
I was using my phone normally, when suddenly my phone resets itself... Normally, i have a pattern lock installed on this guy.. BUT after the strange sudden reset, the lock screen pattern suddenly becomes a pin code lock...
Now i am unable to get into my phone and it refuses to accept any code that i have used before on the phone... anyone is able to shed any light on this bug or how to reset the pin?
thanks!
do you mean a sim card lock code?
nope... i mean the PIN lock by the phone... u know in 2.3.3 u have the option of the password, pin or lock pattern?
it suddenly jus changed from lock pattern to pin code lock over one insane reset...
in that case you can only recover you account thru xrecovery or reintall the rom/hard reset it
You can't hard reset cause' you must enter a PIN code to log in OS man lol. Recommend repair your phone using SEUS. Everything will be fine.
My reccommendation is to not use any passcode or pattern locks... cos 2.3.3 is a little crazy in this area.... that one suddenly system crash made things worse... i decided to pre-set all my codes and lock pattern while i can.. and to disable the locks...
Is'nt SIM code enabled remembered by the SIM card? So any device you stick it in will ask for the code.

If it is to get out of the lockscreen, then just randomly try some pincodes, 5 times or so. A little button pops up asking if you want to reset it by logging into your gmail account.
that should fix it i suppose
My fingerprint scanner stopped working randomly. Did a reboot it worked one more time then stopped again. Now not working what so ever. Im running 2.3.4 unlocked. Anyone know of a fix?

This Link is in the IHOP sticky in the dev section though flashing pudding or titanium is reported 50/50 chance of messing your finger print even if you re-flashed/rebooted or asked it nicely you might wana try this out
Most likely an issue of not enough free RAM for the scanner to initiate the recognition task.
Reboot the phone and it ll be fine. Real saviour is the alternate security code, which is your kickstand in case the fingerprint scanner gets jammed again.
Its not the same issue of that when you use TiBu and it confuses the scanner. My scanner isn't recognizing my finger swipes period. I think the scanner might be dead :-/

Op,
I had the same issue. The fingerprint sensor wasn't detecting any of my swipes. This is what i used to fix the issue. Shouldn't make a difference but i tried this on custom rom/kernel.
Turn off the phone, pull out the battery for 2 mins. Put it in and power on. Go to settings / security / change screen lock / fingerprint
Set up your pin and restart the phone.
Once the phone is restarted, go and identify your fingerprint, it will register the fingers and work as usual.
When my fingerprint thing wasn't working I rebooted and it was fine.
Check that you don't have some task killer killing the fingerprint sensor task maybe?
They don't seem to understand its not responding at all. Mine even does ghost swipes. I haven't found any useful info for this problem either. I don't know what it is because I've flashed back to nandroids that it did work with but now doesn't. It may have changed software that is not touched by backups or its hardware... couldn't tell you which.

Mine wasn't working at all,too. I guess it was effected from all of these roming madness. I just did like i posted #7 and it started to work again. Do you remember if you ever tried to use the fingerprint scanner with wet hands or something else ?
No wet hands. But it did go from working one swipe to not working at all. Ill try the battery trick when I get home as well as reflashing 2.34 if none work I'll assume he scanner died.

Just try the fix I posted above >,> not like it'll kill your not working scanner even more
Rebooting works usually

Thank goodness for someone reviving an old thread. Just unlocked my bootloader (with ltdanno360 help) and scanner stopped working. Doing this worked. Thanks!

Great!!
My sensor wasnt working also, great Tip
omg, this thread just saved my life. I've been with a not working fingerprint scanner for 1 month now. And a simple reboot fixed it.
Just a tip: I had no need for the pulling off battery thing. Just rebooted and worked like a charm.
Thank you very much!
Lately i have not been able to open protected apps with the pattern lock i set. The lock just appears twice and even after drawing the correct unlock pattern, it wont open. It just goes back to the home screen. I even tried resetting my home to factory settings. Aftet that the lock worked for a couple of times and then again the same problem. Can anybody throw some light on this? That will be very helpful.
P.S. i cant find any particular app that might have caused this and i dont have any external app lock on my yureka.
PS I know I copied it from an earlier post but that post was not answered so I created this.
I am facing the exact same problem.
Hi guys
I recently bought an OnePlus 2. With the original firmware, I experienced a very strange and very annoying issue: My screen randomly turned off (e.g. during a chat in WhatsApp). The screen turns off and I have to turn it on again by pressing the power button. Then I enter my PIN to access my phone again and it locks AGAIN. This happens like 10 times in a row, then I have to reboot the phone and it was OK again. I seriously don't know what triggered this issue.
However, recently I got pissed of because I tried to call one of my customers and as soon as I entered my PIN and tried to open the phone app, the screen locked again and I almost threw away my phone. Damned troll.
So I decided to try another ROM as I thought it was an OS-related issue. Now I'm running Exodus Android 6.0.1. I did a clean install and guess what: The issue came back on this ROM...
In my opinion there's only something both installations (my previous 5.1.1 stock ROM and my current 6.0.1 ROM) have in common: I've been using XPosed with Amplify, Greenify and XPrivacy. Other than that, I have no idea what it might be.
Have you encountered the same or a similar issue? If so, were you able to solve it? How did you solve it?
I just uninstalled Amplify, as I think it stops somehow the Gyroscope service, that's why it locks randomly. I'll check if the issue appears again...
I think I have good news for you guys: I guess I was able to locate the issue.
I noticed it always happened when I was holding the phone in the hand I had a ring on my finger. Then I found out the phone has magnetic sensors (for flip covers).
I downloaded the Xposed module "Magnet Sensor Control", the bug hasn't appeared so far!
I hope I was able to help you guys with my findings. This thread may be closed now.
Hi, first of all I apologise if this question has been asked but I don't know how to search just this place.
I'm using everything stock, no root, stock launcher.
I have my phone set up to ask for the password on reboot. I have my fingerprint reader set up to unlock my phone. I also have the fingerprint reader set up to wake the screen.
However under certain circumstances the fingerprint reader does not unlock the phone. The most reliable way to trigger this behavior is to plug the phone in to charge.
I exclusively lock the screen with the power button.
The fingerprint reader is still responsive and it still wakes the screen but there's no vibration feedback and it does not unlock. After I unlocked the phone with my password and lock it again the reader works again.
So what's going on here? How should I debug this?
After reboot it is normal to ask for password first time. Sometimes i have also seen this but when i unlock with pattern (my backup way) and lock again it works fine. I can not trace this to be related with charging or something else and it happens rarely but i have seen it also. Maybe a software bug.
Looking back to the days when i have LG V10 i remember that i had the same problem with fingerprint sensor not working sometimes. It was more frequently related to heat buildup as it was hot phone anyway.
I had the same problem these days, I think the fingerprint reader won't work if your hands are really cold.
Hmm I don't think my U Ultra is getting particularly hot and, no, my hands are certainly not very cold either. This behavior happens indoors.
It's just extra security plan and simple
Sometimes, not very often though, my fingerprint reader refuses to respond. Not even a misread where you get haptic feedback and not a lot else.
Just using the power button and entering my back up security (pattern in my case) and it comes back to life.
I don't particularly worry about it, but I suppose it's nice to see that it's not just me
Will see if the upgrade to 8.0 fixes it.
I met this problem.The solution was very interesting.I use Yandex.disk app.This problem did occur after the Yandex.disk app is update.I hard reset my phone.The problem was not in my phone.But I setup Yandex.Disk app the problem repeat occur.İf you installed Yandex.Disk, uninstall the application.if you don't use Yandex.Disk,The last apps update uninstall to try.
Good Lord I have so many apps installed though...
Then go to a full factory reset and see if it helps, thats the 1st thing you do when you have problem.
After a bit of experimentation this behavior seems to have stopped after I disabled/removed all Smart Lock Trusted Places -- a feature that is already known to be buggy.
I have it too, once a day it puts me to enter the password, its a security or a bug idk.
No more, no less, every time when its charging. I installed some 3rd party apps, its possible that they are to blame.
We will see when 8.o strikes and i will hard reset.

8 fixed this bug for me but i found more bugs in oreo so i am thinking to roll back to 7.0 and meet fingerprint sensor bug again because oreo problems are disgusting - car bluetooth does not works as it should - i can't read addressbook in my car head unit - it shows error. i found that is some bluetooth software parts was not included in 8.0 but successfully fixed in 8.1. and i'am pretty sure we will never receive 8.1 for u ultra.
in russian 4pda forum i found some reports (unconfirmed yet) that fingerprint bug disappeared. maybe somebody here can confirmed it?
No i have android 8 and issue still occurs sadly did not found a fix.
I've suddenly had this issue a couple of days ago a couple of times. I didn't do anything (except a couple of reboots) and it was fixed again.
Now after updating to Oreo and again using leedroids ROM, i didn't experience theissue again..
I talked to a htc representative and said to clear credentials from security/encryption and credentials seems to be a conflict in security certificates. For the moment it works.
