i got a lollipop note edge from at&t and since a while fingerprint sensor stopped working, i tried many times to restore now even used a 4 archives stock rom to reset the phone ans nothing happens, could it be that its a physical damage??
I have a Zenfone 2 and its G sensor stopped working. Apps like Sensor Box show that my phone does not have a G sensor.Whenever I clear cache it starts working for a short period only(around 5-10 minutes) after which sensor box shows that I do have a G sensor but still the test does not work. Recently I installed Cyanogenmod 13 and the problem still persists. Any idea what I can do ?the problem seems software based to me.
I have a problem with the fingerprint sensor.. Since I switched to miui 11 with android 10 the sensor worked at times. It works for a day or two, then the menu disappears from the settings and i can no longer use it.
I try tu update vendor partition, wipe data, format data, reinstall new rom with all wipes, reinstall stock rom with Mi FlashTool, any solution works..When i wipe all, it works for a while and than, suddenly, doesn't work anymore!!
I have Mix 2S, i'm sure that is not an hardware problem..
Replace fingerprint sensor
I don't know why you say that you're sure that it's not a hardware problem, but to me, it sounds like the sensor is broken. I suffered this issue in my own Mi Mix 2s and it was caused because the "cable" of the sensor was folded (it's not really a cable, it's more like a flat plastic connector) and it worked one day and not the next. I finally decided to fix it by myself, looking for a youtube video about disassembling the phone and with these tools and the replacement sensor it was pretty easy (and quite cheap, frankly). I hope it helps!

I had the same problem. Mi mix 2s had a problematic/bad assembly line.
I have exactly the same issue. After Android 10 update the fingerprint sensor works for a while. After one day I recognized that the fingerprint sensor is not working anymore. And there are no options or settings in the system settings anymore. So I assume a software problem.

This problem is very boring!!! Have you try a solution, or a temporary fix???
No, I have no idea how to fix. Seems we have to wait till the next update from Xiaomi, which hopefully will fix the problem. It is really boring.

Your assumption is wrong... these options will not show up if the system can't find the fingerprint sensor... Had the same problem and it turned out to be a hardware fault, exactly like mentioned by Kaliotto. You can do a simple test via CIT (tap multiple times on kernel-version). You will find a fingerprint sensor check in there. If it does not find the sensor, it is broken, simple as that. Replacing the sensor is really no voodoo, did it in a timeframe of 30 minutes myself and it was really the first time I ever opened a smartphone. And the parts are really cheap.

I read on differents sites a lot of people who had problems with fingerprint sensor after upgrading to miui 11 with android 10..i don't think that all of us had hardware problem at the same time of the upgrading, it's very strange...
so, to avoid any doubt, i'm searching a new fingerprint sensor..the site suggested in the second posts seems to have problems with payment, any times i try to buy with paypal o credit card, the payment was refused..so i'm searching another reliable site..
I solved the problem. In my case it was defenitely a software bug. I tried to run the fingerprint test at CIT and the phone reminded me that the phone is protected by a PIN and can not enroll fingerprint information. So I switched of the PIN protection and the fingerprint test runs positive. Since that time, the fingerprint options in the setting was back again and I was able to setup the fingerprint sensor as usually.
So I thing the deactivation of PIN protection was the solution to get the fingerprint sensor working again.

So, you only disabled pin in the lockscreen (and set swipe method to unlock the phone)??
I tried now disabling pin and restarted the phone, but no options in the settings menu
Can you give me more details? Thanks
Update! After one day of use, I have to say, that the fingerprint sensor still does not work proper. After a while the fingerprint sensor stops working again. I played around with the settings, disabled the PIN protection and start the phone several times and than the fingerprint sensor was working again for a while. There is still something wrong. Also the CIT test sometimes pass and sometimes fail. Maybe it is hardware failure after all.
What I did: I disabled the password (PIN) protection, means no protection at all. After that I was able to run the fingerprint sensor test at CIT ( as cdfs wrote). This test was pass and the settings to configure the fingerprint sensor appears again in the system settings and the sensor worked for a while.
Since this procedure the function of the sensor is not consistent and I can not definitely say what to do to get it works. In the meantime I think that all the described workaround just works by accident.
NEWS: i changed stock kernel with two modded kernel (Twisted v22 && LawRun9.0_60hz) and fingerprint start to works again!!!
So, my idea was real: it's a software problem!!!!
Try it yourself and give me your feedback
Hi,
I had also the issue that the fingerprint sensor was not recognized. I replaced it.
Then the option was there again but it doesn't read any fingerprints.
The CIT test fails by the last step "Pixel open test"
Then I got a second new fingerprint sensor and replaced it again.
The test fails again in the last step!
These are the CIT messages:
Autotest: Testing
SPI test: Success
Reset pin test: Success
Interrupt pin test: Sucess
Pixel open test: FAIL
So I would say it is a Software Issue
Hello,
so I at the end found some users, having exactly that problem!
I bought a new sensor and changed it. Pixel Opem Test failed.
I bought another sensor with the same result: Pixel Open Test failed.
Is there a usefull solution?

Hi all.
Last week my Moto g8 plus started to show message finger mooved too fast on locked screen randomly.
Then fingerprint sensor stopped working.
I have removed all fingers from it - no comments.
Now when I try to enable fingerprint sensor - it is not working. When cancelling the setup - phone goes into boot loop.
Did anyone have similar failure? Is it to be repaired by factory reset?
As far as I've searched similar problem appeared on Moto one vision but I haven't found any software solution.

I never had problem with fingerprint but you can try by factory reset ??* if it continues then install a new firmware
Did rescue with Moto rescue and smart assistant. Still the same story. Looks like it is hardware problem. I think I'm gonna request warranty service
Hello there,
So my Xperia 5 lately has fingerprint scanner issue that won't respond to my fingerprints (on fingerprint sensor test it says 'Sensor Not OK'). This issue can be solved by restarting the phone (it's simple tips but take a lot of time for me). Does anyone know how to fix/reboot the fingerprint service on system without restarting the phone? Thanks
Regards
I had same issue. But after couple weeks with this problem my fingerprint scanner broke permanently. I dont think there is a solution for that. Tried to ask in many places.

Does the Fingerprint Manager menu disappear from the setting? If not, your fingerprint scanner still has a chance to work again. Try to restart the device again after several weeks.

Thx for Your advice but it is not true. Sony had problem with fingerprint sensor in Xperia 5 MK1
Xperia 5 Fingerprint Manager missing from settings
Hi Recently I've encountered problems with my fingerprint manager. Since the update it has completely gone from my settings menu on my Xperia 5. I spoke to someone from the team and they suggested backing up my phone and software repairing my phone. This didn't help one bit. And also erased...

I tried restart phone after several weeks. I have fingerprint manager in phone but sensor it is not working.
