Hi,
A few days ago, I was on official Pixel experience rom. Fingerprint unlock started to don't work sometimes. I had to wake up screen with power button before using fingerprint sensor to unlock the phone.
Yesterday, my phone just stopped to react to any fingerprint unlock attempt. I thought that was a software issue, so I decided to migrate to LineageOS. That was a success. However fingerprint sensor doesn't work. Worse : fingerprint settings just disappeared in phone settings.
I would like to know if there is a way to test the hardware part. Or if anyone has gone through this before, any advice will be appreciated.
Thanks.

I had the same, but I do not remember exactly how I solved it. I think by clean flashing a MIUI developer rom, booting into system, flashing twrp again, format data, and flashing my custom rom.

Thank you for your answer. Do you think I can do a full nandroid backup of my current setting, then format to install MIUI, then restore my backup so I don't lose my data?

You should. I had difficulties with restoring a Nandroid backup, but that was probably related to encryption. So by removing your PIN or password it should work. I used the app Migrate to restore my data.

Thanks. I gonna try that when I get some free time
OK, that was a hardware issue. Everything works fine now. The fingerprint sensor flat cable was mounted fold. This must be the reason.
If someone has the same problem, it's easy to fix it by yourself. You can find cheap tools and part on aliexpress, and disassembly videos on youtube. This took me 30min and it was the first time I opened a phone.

Hi
Recently I've unlocked my Z5's bootloader and rooted it.
I installed Paranoid android from the thread in the forum, everything was working fine, even the fingerprint sensor was working quite ok.
after a day I wanted to switch the locking option. so i wouldn't use the fingerprint, and only swipe to unlock the phone.
After i changed the settings the app crashed (it changed successfully to swipe instead of using fingerprint)
Now the result is that every time I try to change this specific setting (Screen Lock) the app asks me for my pin, I type it and the settings app crash.
I tried to restart, Clean cheche and uninstalling some google apps. nothing helps
Thank you for the help! :angel:

So obviously it happened because I am no longer stock, But as my experience goes, I know people may have stumbled upon the same problem in their past, and maybe know a solution that will work for me.
I do not want to go back to stock, Because Sony's Stock is ****, serious **** full for bloatware that you cannot remove and battery life that makes you cry.
Your message was not helpful, but thanks for trying
It most likely is a problem with the ROM installed on your device, as you already performed wipes and the problem persists. Try reporting the problem to the rom dev or if its that important, try a different rom for now
Good luck
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?
http://pastebin.com/6PMeL8QT
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!

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

Changing the app I was using, I clicked on screen pinning accidentally. I was using the infinite screen and tried to unpin the screen of too much ways, but I couldn't. So I rebooted my phone to get it back. But, when he started, the system don't recognized the fingerprint sensor anymore. Simply I didn't had the unlock for fingerprint option anymore. I tried to wipe (almost) everything, but didn't work. I tried to install other rom, and tried to install a gsi, but all that roms and gsis simply don't recognize that phone has an fingerprint sensor. I think that the problem was with the screen pinning and that created an bug on system. What I do?
I installed an app that test the fingerprint sensor, but he showed an error that said "this app only works on phones with fingerprint sensor.
I was using MIUI V10.2.2.0 stable when it happened

Hard reset. If you have done that than flash stock rom with twrp or fastboot.
You have just messed up with settings so hard reset will make you fingerprint working

Simple..just go to service centre and ask them to reflash the software. If your device will be in warranty then they will fix your problem at no cost.

Hi friends,
Since yesterday, my wifi and bluetooth don't work anymore. When enabling them, it scans nothing . I've made a factory reser without any psuccess !
Never seen an issue like this on any phone...
Thanks for your help guys
Have you tried restarting the phone? I had 1 time yesteday too, suddenly, the phone was idle, and when I checked Wifi found nothing. Restarted and then it works again. Not sure if related to March update or some other stuffs

Wow...after a factory reset, that's pretty much it!
You can try doing the reset network settings button (you can search it in the search bar in Settings or find it in the Internet setting on top right button [wrench and reset circle]), but I can't imagine it doing better than a factory reset.
The best/last thing that can be suggested, since it states you are rooted in your sig, is to flash the latest Full Factory image (March) and/or with the "-w" intact (since you stated that you did a factory reset so I imagine your phone is wiped anyways) and see if that doesn't fix the issue. The best 3 methods to achieve this is using the online Android Flash Tool, the tool PixelFlasher that can be found here on XDA, or manually using platform-tools (you must've used one of these in the past to be rooted, so I assume you're familiar).
Hopefully you get it figured out. Worst case, the phone is still under manufacturer's warranty and you should be able to get it replaced with a refurbished if it truly isn't resolved...

Btw I tried the reset network thing without success

Mmmm...when you stated you "factory reset", it wasn't clear whether it was from the OS system setting or when flashing...
I don't think there is a "better clean" way to flash and/or reset the phone. If you're not flashing/sideloading OTA (which you aren't)...
It (reset network) was a very long shot, but worth exploring just in case it hadn't been tried yet...
I mean, I guess you can try Android Flash Tool and even go as far as to flash to both slots and relock bootloader to get a pure, stock status and see if the problem truly sticks that way. You've already wiped the phone, so I doubt this could hurt or you lose anything important at this point. But I can't imagine dirty flashing the latest March update (or even including disabling the verity stuff) wouldnt've addressed or reset things to set the issue straight...
If it's still there after relocking the bootloader and flashing to both slots, then it's warranty exchange time (if you ever want to resolve the issue)...
*most likely the flashing somehow wrecked the system board radio enough...
If/When this works, you'll need go through the trouble of unlocking the bootloader, and reflashing the Full Factory image with disabling the verity & validation stuff, before rooting again.
Ok I think it's a hardware problem. When I shake my phone, I hear something moving.
I dropped it from my bed saturday night. The wifi module must be disconnected.
Let's send it to Google....

Are you sure that what you are hearing move when you shake the phone is just the OIS for the camera? All phones with OIS will make some noise when you shake them.
