So, I took delivery of my G4 plus less than ten days ago.
Everything worked fine, except that the fingerprint sensor occasionally acted up. It would often fail to recognise my fingerprint, about one out of every ten scans; but i assumed that my dry skin had something to do with it.
Today morning, upon waking up, I noticed the phone had become unusually hot and switched it off for the first time in nine days. When I turned it on again, the fingerprint sensor was totally dysfunctional.
I tried unlocking with the sensor. No luck. Forget sensing my finger, it wouldn't even vibrate to indicate that an input was detected.
Tried searching for fingerprint sensor in settings. No luck.
Dialed *#*#2486#*#* for CQATest. Attempting to open the fingerprint sensor section resulted in an FC.
Performed a factory reset. Back to square one, still no fingerprint sensor. Initial setup wizard simply behaved like the phone has no fingerprint sensor.
All subsequent attempts to get it to work have failed.
I've been using pattern unlock, and while everything else works fine, the sensor seems to be unrecognized by the phone.
My guess is that it's a hardware issue, but I'm baffled by what caused it. I've been extra careful, never dropped it even on a bed. No water contact. It's stock, no sideloaded apps installed and bootloader untouched.
Google searches proved useless, as did a thorough search of XDA, Moto's forums and a subsequent call to Moto customer care.
Would anyone happen to have a solution? I've requested a replacement from Amazon, but it would be nice to have a quick solution handy if this issue crops up again in future.
Thanks!
check whether in the security settings you get a fingerprint settings. if not search in the settings searchbar for fingerprint. if nothing worked try installing a applock "applock" and try to enable fingerprint within them and try to unlock. an important thing is this one, try using a full screen app of your choice and tap fingerprint sensor. if it opens the softkeys your mobile is messed up with software, if it didn't open the softkeys then the mobile is messed with hardware. cheers

If the phone is still within the replacement window, get it replaced. Otherwise, you can:
1. Get it repaired at a Moto service centre if within warranty period (that way you won't lose warranty)
2. Get it repaired at a local service centre (only if warranty has expired and Moto is charging higher for the repair)

How do you get the phone to recognize youe fingerprint? It is so annoying how it keep failing to recognize the fingerprint and asks to enter the code or pattern.

Go to Settings -> Security -> Nexus Imprint. Follow on screen instructions to register your fingerprints (up to 5).
I believe there is a setting to not have to input a code every time, check to see if that is your issue. I only have to enter a pin after a reboot, then just the fingerprint unlocks the phone.

I didn't explain myself well I guess. It happens to not recognize the fingerprint and then asks for pattern/code. It is annoying.
First I would say to clean it well. Second i would suggest you reset the print and add extra sets too. Also what ROM, firmware ect are you running? I have had flawless experiences with my sensor across various ROMs. I do a full set scan for 4 fingers. My 2 pointers and my 2 middles as well as another scan set for odd positions. This ensures no matter what I'm holding or position my phone's in it will be easily unlocked.

Running chroma 2/3 build with february firmware but I don't think that's the issue. I will try to register it again. Thanks.

I've had the same problem since the last week after updating a resurrection remix version. I think it's been doing something weird, but it'll unlock normal in the car and stuff so I don't know. Seems like when I put my finger on the sensor it will wake the device and want me to enter a PIN. If I put an unregistered finger on the sensor it won't wake it it'll stay black screen. It might be something to do with when you are at home with smart unlock. Hmmm....

I thought it could be the smart unlock and removed it but still same thing. Might have to go all stock and test it again. I had another nexus 6P before and that one you get unlocked really fast without any issues.
Edit: Found the issue. Double tap to lock ftom Nova was forcing the device to request pattern or pin.
Hi guys
It's a couple of days that my fingerprint sensor won't work at all.
When I tap on fingerprints in settings it shows the message of the first attached pic.
Obviously I've tried to restart the device, shut it down and booting lots of times. It used to work for a while, but then the message will reappear.
Dialing *#0*# and going to the sensor sections shows just "null" as it doesn't even exist.
I've also tried a factory reset. Didn't worked.
Tried to wipe data files and cache from app manager. Nothing
Any ideas?
I still have the warranty valid, but there's a mark on the bottom of the device caused by falling. Will they accept warranty anyway?
Thanks to all
They probably will repair under warranty, you've got EU consumer laws on your side, if you've had it less than 6 months it'd be more in your favour generally.
When i use a software like S view app to use proximity sensor to turn off the screen with a generic S view cover he turns off but when i open and try to use fingerprint he always ask for the pattern, but if i use the power buttom to turn Off, when i turn on i use normally the fingerprint and don't ask for the pattern, any solution to make the phone work like the power buttom with proximity sensor?

Everyone is having that exact or similar issue with fingerprints..
After doing some research about this issue I found out that it's
due to a new security policy that was added to the updated
S7 Edge firmwares.
If you want you can make a nandroid backup of your rom and
odin flash the original S7 Edge firmware for your phone and you
will find that the fingerprint problem will no longer be an issue.
Good luck,
Have a great day...

The phone is unrooted, i have it for a couple of days... :/
Any work around yet for restoring a backup from a previous device and putting into a new device. I am in this boat due to my phone falling out of my pocket on a roller coaster and having a piece of wood go through it. Magically still turned on though. Anyways I am plagued with a successful restored backup on the new device and the finger print sensor will not work because the data is from the other original device.
Yes I made sure to delete the lockscreen.db before I booted it up. Everything works perfectly besides the fingerprint sensor and you cant set it back up. If you try it says "Enrollment was not completed. Fingerprint enrollment didn't work. Try again or use a different finger." Also says "fingerprint sensor not available" at the lock screen. If you wipe data then it will allow you to reset it and it works great. My question is does anyone know what needs to be removed or deleted to allow you to use this nexus print feature again? Thanks in advanced.
Suffering the same problem; did you get anywhere?
Probably not. Just have to factory reset. It's not that bad...
It's a small thing, but it bugs me in my daily use of my phone. I recently got my A40 and upgraded Android from 9 to 11, and now I can't lock the phone by touching the fingerprint sensor anymore . But unlocking works fine though. I have been googling around but noone seems to have this problem.
Do anyone in here have aclue to what might be the problem here ?
Since when could you even lock the phone using the fingerprint sensor?
Nonetheless, this is the XDA community of developers, and im sure a random person just needed this functionality on their phone, so they made and app for it..
Anyways, here's a link to a tutorial. It covers exactly what you want, and apparently the app is developed by a couple of XDA developers, so it should be safe too

From the get-go, when I bought my phone. Thought it was normal. My old Moto G5 did same thing. Really handy when you just need to view whatever is on the screen for a short moment.
Locking the screen means turning it off.. (and locking your device so that you have to scan your finger or use a pattern to unlock it again)

Otherwise yes, the phone's screen will turn on on the lock screen if you touch the sensor and the fingerprint isnt recognised. That's not the same as locking your phone. Locking your phone is the equivalent of pressing the power button once, which puts your phone into sleep and forces you to unlock it again (via fingerprint/pattern etc)
Can you clarify what you're asking for here?
Do you want the screen t oturn on when you tap the sensor or do you want the screen to turn off when you tap the sensor?
And do you want it to unlock when you tap the sensor, or do you want it to turn the screen on onto the lockscreen so that you can see the time/notifications etc?
(The links I posted are for LOCKING your phone using the sensor (turning the screen off and locking it, causing you to have to unlock it again when you turn it back on), because that's what you asked for..
