Fingerprint not working after factory reset on Oreo - Samsung Galaxy S7 Questions and Answers

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.

after spending quite a few hours following "tips" and directions from various sources, factory reset was the only one that resolved the incompatible <blah> shared user id issue!!
I think my issues were when i flashed the JB rom with mobile odin..
First i was on PA3.5 and it wouldnt work for some reason although at the time i was very tired as waiting a very long time to download the rom with slow speeds so maybe i did something wrong?.decided to flash recovery back to earlier version of Skyhigh Rom that was working ok then from here i installed the new stock rom over the top with mobile odin.It booted up and gave the android is updating screen.then loaded up with my custom launcher from the skyhigh rom.I thought this was funny as really should have wiped everything.I didnt even get the language change screen or set up its like it kept my old settings from skyhigh.Its as though it updated it and kept everything similar to an OTA update.as posted had the problems with Maps But then factory reset fixed it and wiped it clean again.This time i got the Laungauge screen on start up and the new stock lock/home screens..

FingerPrint not working! Please HELP

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.

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

Note 10.1 unresponsive to touch but S-pen works fine

So 3 days ago I got bored of Android 4.4.2 on my 6 years old tablet. It worked fine for browsing the internet and watching youtube but I wanted more. I thought that was installing a new android an easy business but I was wrong. I downloaded TWRP and lineage os android 7.1. for my N8000.Then I flashed my recovery and later I download a sketchy rooting app from an internet called "iRoot". Then "iRoot" downloaded and installed an app with some Chinese characters. I wanted to delete that but there was no icon in "manage apps" tab
then I disabled it in other tabs and rebooted my device. when my device rebooted my touchscreen wouldn't work. I pulled my S-pen out and it worked perfectly fine (the device was never dropped). So I tried factory resetting my device and the problem was still there. I installed SuperSu app I thought that it would help me but when I open it it said ''binary occupied''. I was hopeless. Then I installed lineageOS and the problem was still there. I tried going back to my old android 4.4.2 but my sd card was corrupted. I installed Odin and flashed factory OS for my device. now I have the same problem. btw this was my first time doing this stuff so I made a lot of mistakes. I saw people fixing this problem simply by calling *#2663# but when I do that my screen flashes back and then it forwards me to my home screen. The problem was still there. Do you guys know the solution?

Its the rooting app that is your problem .
TWRP install via Odin wipe data system cache etc reboot to download mode .

I wiped everything. I just installed Factory android 4.4.2 with Odin. Then I installed TWRP 2.8.4.0 via Odin and wiped everything. but my touchscreen still doesn't work even in TWRP. I was installing Lineage 14.0 from this thread https://forum.xda-developers.com/galaxy-note-10-1/development/rom-lineageos-14-1-t3848514 and I ran out of time. I will update you guys tomorrow. :fingers-crossed:
So *#2663# doesn't let you reflash the tsp firmware?
If not, your tsp ic need to get replaced.

What do you mean by that? Do I need to replace my digitizer, motherboard, or something else? I'm quite new in this type of stuff so I don't understand most of the things
Also, I tried installing multiple versions of official os and other versions of Lineage and Slimroms and my touch still doesn't work. I also tried reflashing firmware on all those versions but it still work.
This menu which appears, when you dial *#2663#, it let you update the touch screen panel firmware,
it flashes it directly to the chip.
If this fails or simply doenst work, you have to replace this chip (TSP IC) or your mainboard.

Thanks for your quick response. Basically, because this tablet is over 6 years old, and I am unable to find the correct motherboard in my country. I found tablets (used) like mine for something near 40 euros. I wanted to buy a whole motherboard and replace it, but it was like 30-40 dollars and shipping is an additional 50 - 60 euros. So I think that I should wait for a cheap broken one and then try to make Frankenstein from those two. Anyway thanks for your help!

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...

Yesterday I dirty flashed March update bmand disabled verity stuff. It forced me to format data. Is it enough or is there a better clean flash way ?

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.

I don't know my friend. Google will send me the return process tomorrow. They told me 7 to 10 days for repairing. Why did I sell my old oneplus ?

I have had several OnePlus phones and they have all been great for me! However, I am having no problems with my 7 Pro either so....YMMV
