Fingerprint Hardware Not Available

So, I got my 6P last monday. The Nexus Imprint seems to be missing on the security screen and the scanner does not work as when I set it up. Now when I restore the factory image it doesn't even show up in the setup like I did the first time I set up the phone. I tried clearing cache like another did on reddit per google's instuctions, but and it worked for a bit, but now it won't recognize anything at all. I am in communication with Google support, but wondering if anyone has ran into this problem?

The same thing happend to me this morning. Google Store support is sending me a replacement.

Just happened to me and I didn't even have my nexus a day. Already ordered a RMA device smh.

It happened to me after not even 4 hours of use. Mind you I set it up with one finger then deleted it. It has had maybe 10 presses.
When I try to access nexus imprint settings, I get the "unfortunately, settings has stopped" message.
I have only been configuring my device to have the same settings as my nexus 5 and deleting random google apps such as books - non essential ones then the fingerprint wouldn't respond. I'm not going to RMA the device for the failure but will try to isolate the issue and ascertain if it is hardware or software.

Yea they are replacing mine..... In the mean time it started working. So weird....

Does this actually mean its broken, though? I got this message, unlocked it with a pattern and not it works again. It might just be a process that wasn't running for some reason.

samething happned to me too. I downloaded the stock factory image (latest) and flashed and vola! it worked

Just happened to me, first time I've had a new phone go bad on me. Not excited about rma"ing it.

Wow! I just got off of a chat with Google and they need 1-4 more business days to get with me. No RMA or any type of answer. I don't get that if they have had other call in with the same issue.

Did you try to flash a stock image and see if that solved the problem? Might be something to do while you wait.

I have the same problem, i.e. no prompt about Nexus Imprint during first setup and no mention of it anywhere in the settings. I just flashed the MDB08M stock image and it didn't help. This is so weird. I guess I'm doing an RMA...

That's very strange. If I had to take a guess the imprint settings may only appear if the finger print scanner is detected as connected. Perhaps on a few units the fingerprint sensor isn't connected properly.
I want to make sure as well you guys flashed complete stock including kernel and locked the bootloader without having a corruption screen appear?

Yeah, after locking the bootloader again that boot screen disappeared and everything looks normal. I returned it to the store without any problems.

FYI, I had the same problem were suddenly my 6P fingerprint sensor stopped working. It would give me "Fingerprint sensor hardware not connected" or some similar error on the lock screen when I pressed my finger against the sensor. After a reboot the Nexus Imprint section went away in my security settings.
I contacted Google via their device support chat system, they pretty quickly jumped to a factory reset as a solution. I followed through with it and it resolved the sensor issue (during initial phone setup it worked perfectly). I prodded the tech for more information to the root cause and didn't get anywhere besides it potentially being a 3rd party app conflict.
I'm on stock Android with Feb 1 security patch and Google Fi when this happened.

I'm on Bliss too at the moment and also missing finger print.
As I also miss slim pie, I'm trying other roms too. So far all of them did have finger print working.
(Still missing Slim pie, trying Benzo rom next.)

I rooted again and flashed blissrom and it's working again now fingerprint.... I flashed the version I was on before the problem happened.... Not sure whether to update again... Maybe I will wait for the next newer version......anyway happy its working and not some hardware fault.

PIN locking problem

Is anyone else experiencing this issue. The device was locked with a PIN and fingerprint recognition. During extensive use last weekend the lock would disengage meaning the device could be opened by merely swiping. I therefore removed the fingerprint recognition and reverted to PIN only. However again after extensive use the lock was bypassed.
When you switched on the phone the screen showed "Swipe screen to unlock" If the padlock was below this phrase it was open and no PIN was required. You could however press the padlock and it would jump to be above the phrase and then required the PIN to unlock. However after switching off the phone it would often revert to be "open".
I can't seem to find anything about this by googling so would welcome suggestions.
Thanks,
Brian
PS If the phone is only used lightly during the day the device remains secure.

That sounds weird. Upon a restart the phone will always ask for the alternative method of unlocking (pin or password for example) rather than simply unlocking with fingerprint. But after that first time it should work fine. Personally, I have mine to set to unlock with only a fingerprint. Perhaps the fact you use both at all times could be causing the issue?
Are you on vanilla stock the phone came with? Have you tried updating it?

Thanks for the response.
I thought it was weird as well as the S5 never had this problem but of course it did not have fingerprint unlocking.
Yes it is Marshmallow straight out of the box and has had one update so is now running 6.0.1
I did sometimes have a problem with the fingerprint recognition so I would be reluctant not to retain the PIN!!!

S5 did have fingerprint unlocking, it was simply not as good as you had to slide your finger down the button. It did work though.
I recommend an update. Or, if you don't mind tripping knox, install one of the custom roms on this site or one of the other roms off site (like the one listed in my signature). Each new release of these custom roms are normally built on the latest base that is out there so you would hope any bugs like this would be fixed, assuming it is a bug.

Thanks, I'll give it a go. After the Lollipop upgrade bricked my Asus Nexus 7 I have been reluctant to do upgrades unless absolutely necessary.

Pattern changed by itself?

Hi,
Has anyone ran into this issue where the pattern changed itself or no longer worked? I definitely did not update or change it. All of sudden today, it just stopped taking it. Initially, I was able to unlock with my fingerprint. However, when I went into lock screen settings to try and figure out what's the issue, it prompts of course for the pattern. It then of course said it was incorrect and then told me to try again. Now I'm currently locked out 60 minutes and my fingerprint doesn't work anymore either! This is such an annoying bug and have no idea how this came about since I haven't updated or downloaded any new apps. I've also rebooted several times as others have stated, and the problem persists..

This worked for me!

Hey- I had the same issue happen to me yesterday. I was able to accidentally find a solution by following these steps
1. Turn off your Android device.
2. Press and hold the "power", "volume down", and "bottom" buttons simultaneously. ...
3. Release the buttons once your Android device is powered on.
4. A Warning screen will appear, press the volume down option to cancel and (restart phone)
5. Phone will restart and ask for your pin, the original pin should now be working again.
6. Add your other fingers to the scanner! - at least that's what I did

Somebody else having problems with their fingerprint reader?

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.

stuck on "pixel is starting" fix

Thanks for stopping by,
I've had this issue a few times now where I'd restart the phone and would be stuck on the "pixel is starting" message for hours and while googling could only find a factory reset would fix the issue. So instead of resetting for the forth time I figured what do I have to lose if I had to reset anyway. Finally got it to start up without a reset. Here's what I did.
1.reboot into twrp
2.advanced>fix recovery boot loop>reboot
3.reboot back into twrp>flash magisk
4.profit!
Hope this helps anyone that runs into this.

I've always been able to three finger salute it and it boots up. Shouldn't ever take more than a minute or two.
Sent from my Pixel 2 using Tapatalk

Update:
Was able to reproduce the never ending pixel is starting.
Turns out it was the fingerprint unlock after reboot tweak I use.
Turned it off and issue is fixed. Turned on the issue returns.
Think it may have to do with the encryption after fp are entered.
Really enjoyed not having to enter a pin on start up. I can live without it though.

I flashed Magisk without TWRP and I was stuck on the "Pixel is Starting" on my Pixel 3. I found this thread.
I turned my screen off, let it sit for a minute, then turned it back on and it said it needed to be unlocked. I did it again, then used my Fingerprint to activate the "unlock" screen you see after a fresh reboot.
It let me put in a pattern and opened fine.
So yeah I think it does have to do with encryption \ Fingerprint but it looks like that way just let me beat it -- hope that works for someone.
