My fingerprint scanner is not working. It works after i apply some force on it but after a long time. I have deleted my stored fingerprints then it worked fine for a little bit of time but again it is not working. I have done hard reset but nothing happened. I think the problem is software related. I have read some previous thread related to this problem , the solution in them was hard reset i have tried it but it isn't working. maybe problem is the update. Please help me.
my version: MT7-TL10V100R001C00B128
If it's software related please flash other rom. I've never had any issues with the fingerprint scanner.
You could flash the B120SP04 since that was the version when I bought my phone. And I never flashed B128.
I went from B120SP04 -> B130 -> B331.
Anyway, you can try B120SP04. If it still doesn't work then you might have to send it to your nearest service center.

if i restart the phone its work for few mintues
Weird because I don't have this issue. However I had to perform a factory data reset through stock recovery because my internal storage was reading 16gb not 32gb. I mention this because maybe that'll help u. Plus I'm completely stock so far.
Have the same issue. Its so annoying. My brother and i did the updates on 2 phones. Mine has the issue, his is working fine. Any solution
I'm having the same issue, I pushed the OTA update via ADB first and has this issue. Then i tried A factory reset and still had it. Then I tried flashing the factory image using fastboot and I'm still having this problem. Everything else seems to be working great.
Do you guys think its an app related issue?
I don't think so, i booted into safe mode and still had this problem, unless the issue is being caused by a native app.
Yeh tried that too. Same thing. How come my brothers phone is fine tho
I don't know man, hopefully someone with a bit more knowledge will be able to help us out, glad I'm not alone though lol.
I fixed mine! I just needed to re-install my factory image manually. Follow the directions in this thread and use method 2.

I thought I do that on my phone too with no success. I used the nexus toolkit tho. Does it make a difference
*EDIT*
Never mind, it's still broke, I let the phone sit for about an hour and when I came back the sensor wasn't responding again.. I give up.

what if it is an application that is causing this?
No sorry, it took about an hour but the problem came back. I didn't have any apps downloaded yet and it still happened. I would try though, can't really hurt anything. Maybe it will work for you. I'm just tired of rebuilding my whole phone every time, I'm going to ride it out maybe someone will figure something out.
Can you guys try disabling google play services. I have it disabled for 30 min now and looks like its kk
Is yours still working? I just tried this and besides making the phone generally unusable it did nothing, sensors still didn't work. I think I may flash back to 4.4.4, I'm really tired of all this tinkering just to get things working correctly.
Nope. Didn't work. Is your phone a replacement phone by any chance? I called google they acknowledged a firmware bug. They will get back to me soon
No, mine is a launch device. Did they tell you any specifics?
Sensors work fine for me.
Hi there.
After my attempts to get my H8 as stock like as possible I realized that the Fingerprint ID settings got lost in the process. Directly after oem unlock I flashed latest twrp and did a backup. But after restoring that the fingerprint setting was still missing.
I googled the problem but didn't really find any similar case so maybe someone can give me a hint. Is that something that might be to recover from the twrp backup? Does anyone know the settings "name" internally?
I am a little bit lost here. It is not a complete dealbreaker but the few times I could use the fingerprint sensor I was quite surprised how fast and flawless it worked.
The smart key feature still works btw.
-- Update --
Here is the logcat right after reboot which mentions 'fingerprint' - the device complains that "/system/bin/fingerprintd" cannot be found. Which is definitely there. So it really has a problem with the underlaying fingerprint software/driver system. Don't think its hardware related.
Any suggetions?

I've done this. Depending on which firmware you are on, you should flash the boot.img corresponding to the specific firmware you have on your phone. Trust me, I went the long way around to figure it out. Twrp doesn't seem to restore everything on my device, frd-l04.

Hi,
After updating to 7.0 nougat by official Europe update,
My fingerprint sensor stopped responding, when I'm trying to add new fingerprint it wouldn't let me even try, It shows a message (Attention: make sure that the home key is clean and dry, then try again) and then it goes back to the main lock screen settings menu.
I'm really desperate, already tried everything, plz help!
:crying:

Have you tried to factory reset or just flash android 7.0 with Odin. I would recommend wiping after installing an update like 7.0 anyway updating always causes bugs and issues for me.

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
- flashed the stock firmware G935FXXU1DQB3 with Odin
Please advice, thanks.

If you have tried to flash stock firmware in Odin, I'm really not sure what the issue is, if it was just a glitch in the software it should probably have been fixed by a wipe and flash with Odin. If your phone is still under warranty I would bring it back into the Samsung shop or contact them over the internet to inquire about fixing it.
The same exact problem has happened to me too . I'm tired of unlocking with patterns
What should we do ?
This cannot be a hardware issue cuz phone was fine right before the update

Do you still have the issue ?
I have the same problem ???
What the way to fix this issue
I had that problem sometimes and in the end the main reason was really sweat on my fingers and dirt on the home button.
I know this doesn't sound like a solution, but it surprised me as well. Just try drying your fingers and clean the surface of the home button.
Hi There! I encountered the same issue earlier but then suddenly my fingerprint sensor works normally. The last thing I that I made changes to my phone was to reset the password of my samsung account. Not if there was a security breach that happened but after resetting the password, works fine for me. I suggest that you back up your phone's data before and after resetting your Samsung account.
I have this problem for 1 year, tried to change the password but didnt work.
IS someone still struggling with this problem ? Yesterday i upgraded to DevBase 6.0 Oreo newest build. But after the flashing process the fingerprint sensor act in a unusual manner. Sometimes i could unlock the phone sometimes it directly jumps to the pattern unlock screen. Any news about the problem ? I wiped cache/dalvik and i resetted my password of the samsung account - nothing helps.
Any help, ideas, links are highly appreciated
Cheers

Hi everyone, i updated my device to oreo via OTA and everything was fine. Today i did factory reset because of battery issues and after that fingerprint stopped working. When i try to add fingerprint it keeps saying "Make sure the home key is clean and dry then try again". I did everything even rooting and installing custom ROM but with no result. Do you have any idea how to fix it ?
thats weird, maybe try another factory reset?
if that doesnt help: do you still have warranty on your phone? maybe u can bring ur phone to samsung shop because something might be wrong with the sensor itself (just a thought)
It is a software issue, changed a lot of custom roms (oreo 8.0) but with not succeed.
Hi guys,
My V500N got an update yesterday and after it was installed fingerprint scanner stopped working to unlock the phone. It is still active and working correctly in all other cases, but as soon as the phone is locked I cannot use fingerprint.
Another clue to troubleshooting may be that I have installed ButtonMapper app to set Assistant button to enable a flashlight. And this function behaves the same.
Any ideas how to fix this?

Thank you.

Thank you for an advise, but it is not an option right now for me. I have nowhere to make an external backup.
