Hi,
I've recently updated my N910F to Marshmallow (official). It's not the latest version but I wasn't able to download that one yet.
I made a fresh install with it (factory reset via TWRP, flashed it through ODIN, rooted via CF Autoroot, installed TWRP 3.0.2-0 and XPosed v84, restored Apps trough Titanium) and even reflashed it with a wipe of system, cache and dalvik cache before because of problems with auto rotate.
But the Fingerprint API or something like that seems to be not working how it should. I can't set screen lock to Fingerprint (I get asked "Enter a backup password.", wenn I enter one, it just says "Sorry, try again" without saying why it failed), even after going to security settings and deleting the credeintially, which fixed such problems on 5.1.1 it doesn't work.
I also had read, that you could use your Fingerprint for authentication in PlayStore, but at least in version 6.7.12.E I can't see that option.
PlayStore should use the API of Nexus Imprint for that and I thought that this is required by any OEM that want's to get a license for M, so I don't really see why it doesn't show up.
The sensor itself seems to be working, I was able to register my fingers and with FingerLock, an app locker designed for Samsungs proprietary Fingerprint API form earlier versions, I also have no problems.
I think, Samsungs own implementation is working (accept for Lock screen but they´could have changed it here for the official one), only apps for Googles standardized one are failing. But I can't really prove it. An app, that should be using the official API in M is failing, but the developer says it's a problem only with the Note 4 and he hopes he can publish a fix later this month.
The app locker MaxLock, which I thought would use fingerprint authentication with the official API doesn't show up an option for that but maybe through problems with the implementation.
Is there any way to test what's going wrong?
PS: sorry for the long text
I now have this..... Any solution?
Get a (non-TW based) custom ROM. It's the only thing that's works since Samsung most have screwed up the whole API. Their own is only useable partially and the standard one by Marshmallow is completely messed up and not worrying at all.
I was so pissed off of Samsung's incompetence that I switched to emotion ROM. It's a bit tricky to set up the fingerprint reader, but once it's done, everything using the official API is writing flawlessly. Never gonna switch back.
So i have recently updated my phone to the latest 7.0 software on my galaxy s7. ever since the update, my fingerprint scanner doesn't work. When i go into the system settings to try and setup new fingerprints it gives me the error "An error has occurred with the fingerprint sensor. If this message appears repeatedly, restart your device." I tried restarting the device, clearing the app's cache and data, as well as clearing the system cache in the boot menu. When i go into the FingerPrint test under the HwModuleTest(*#0*#) and perform a normal scan, everything comes back as failed. Is my only option to backup my phone and do a complete reinstall?

Try completely reinstalling QA6. I highly doubt the update caused the fingerprint scanner to start working though since it works perfectly fine on my phone.

Flash PK1 with Odin and take the ota again. When the ota is done, factory reset the phone to make sure any software issues are gone.
Should I be using smart switch to backup my contacts/messages/etc to my computer?
I recently updated my phone and am having the same problem. Have you found a solution for you that worked (I also tried wiping my cache partition and a soft reset)

I also just updated my SM-G935FD via OTA to Android version 7.0.
Since then, fingerprint scanner is not working. Like for OP, all tests fail under HwModuleTest.
I tried to remove all fingerprints, but it is impossible to add new fingerprints - the error message is "Make sure that the Home key is clean and dry, then try again." Obviously, the fingerprint sensor is as dry and clean as it was before the update (when it worked perfectly).
Since then I tried, unsuccessfully:
- removing old fingerprints and adding new fingerprints (does not work, cf. above)
- formatting cache partition
- performing a hardware reset
Please advice, thanks.
P.S. I do not have access to Odin, since I do not have a Microsoft OS.
I had constant issues with the ATT firmware's fingerprint reader performance (6.x) -- wouldn't recognize my fingerprint when I tried to unlock and would often get the forced timeout.
It works flawlessly for me on the u firmware (still 6.x unfortunately). Night and day.
Same issue with me here in the UK. Just did the Nougat OTA update, having no end of issues, including the "dry home button" stuff with the fingerprint scanner. Also, the stock browser seems to have lost it's secret / incognito mode.... why can't they just leave stuff alone? Seems like my only option at this point is to downgrade back to marshmallow and put up with the annoying update notification.
Same here what do we have to do ?

Has anyone had, conversely, an *overactive* fingerprint sensor?
While the phone is unlocked, at times when my finger is only resting on the scanner, I'm taken to the accessibility settings with an alert asking "Grant Permission: Please, grant permission to allow this feature".
Hi!
I just normally restarted my phone and the Fingerprint ID is gone from settings. I can't get it to work. I'm on Nougat (L21C432B370) with root.
Thanks for helping :3

Same with me but im stock
If its gone frome settings, then the Phone cant detect the Fingerprint-Reader Hardware.
Installing magisk disables fingerprint reader. If you did so, re-flash your boot.img and will fix.
If it's not in settings, could the cable for it detached or stopped working.
Or maybe it's just a bug.
Disable magisk hide in settings
I have a problem, regarding fingerprint enrollment. Whenever I try to enroll fingerprints after 2 enrollments, automatically 3 ghost fingerprint comes and when i try to delete them, my fingerprints gets deleted instead of them! Can someone help me on this?
What ROM are you on, any modifications (e.g. custom kernel) and what device? Also, have you/did you update to Nougat before the enrolment issues started?
I just got my G6 H872 (new in box). All I have done is unlocked the bootloader, rooted, and installed TWRP & Magisk. Only module installed is Viper4Android. I have not removed any apps via Titanium, nor any other system files or mods. Set up my pin and am trying to set up fingerprint. Unfortunately, every time I enter the pin to set up FP, the System app crashes.
Any thoughts? (Logs in post #3)
EDIT: Facial unlock was working...I tried to re-do it while wearing glasses but the pin wouldn't let me back in. I then removed the pin for unlock and tried again. Facial ID won't let me in no matter what - the pin just doesn't work to continue. AND fingerprint continues to crash the settings app.
EDIT 2: ARRGG! Now I lost Smart Lock/Trusted places! WTF! Had it working earlier now I can't even find/access the Smart Lock settings.
ESIT 3: Got Smart Lock/Trusted Places back. Entering pin for fingerprint still crashes Settings, and the pin does nothing to get back into face unlock.
Really frustrated!
Tired of editing my post LOL!
I can access Face ID now. I had ticked Don't Keep Activities in Developer Settings. Unticked it and it started working. Fingerprint is still a no-go though.
Hoping for some guidance/advice.
Thanks
I have grabbed logs. One from alogcat and the other via ADB. I have no idea what I'm looking for but it would seem to me that the log from ADB is more complete. If there is anyone that can help decipher this, it is greatly appreciated.
FYI, XDA says the log from ADB is too large so I have linked it here.
Thanks!
Fixed my issue by updating to 20g with this. Thanks!
