Fingerprint sensor not working
if this keep happening, restart your phone.
I am using Note 20 Ultra N9860 and my fingerprint sensor is not working anymore.
I've restarted the phone,
event reset the phone but nothing works
Actually I also refreshed old firmware, thinking that might help but nothing.
is there a way to re-flash biometric firmware or anything?
Thanks

I have not seen biometiric firmware as separate flash-able peace, it is always in security patches .. If you did factory reset and problem is still there, i am afraid that you will need to contact Samsung ....

i have the same problem here
Strange, because I also upgraded to 21w MM and I have no issue adding/removing fingerprints.

Have you got LG H900? And you managed to update it without any subject issue? Wow! Because everybody is facing the same issue after 21w MM update on H900. Could you guide how you would manage to do that? Any help would be really appreciated.

I sold the device few months ago, but yes I successfully upgraded to 21w MM and everything including fingerprint was fully working. I used LG Up It was H900 At&T variant of course.
I bought this phone a week ago. Received a system upgrade notification and I upgraded Nougat from BLN-L22C675B150CUSTC675D001 to BLN-L22C675B340CTSTC675D002. The upgrade process was successful :good:. But sensor is not working to unlock the when screen is off & touch response is also degraded after upgrade activity. Prior to upgrade both functions working without any issues. Can anyone please help me to resolve this issue. Thanks in advance

Did you try factory reset??
But your sensor still work or not? I mean, if you touch it you feel vibrations when the fingerprint is wrong, or not at all?
Hello devs i need to downgrade s7 back to marshmallow.. is that possible by flashing m frimware ?
Anyone have tried downgrading back to Marshmallow after updating to dec security patches?
I've downgraded to MM from N a few times. Pretty simple, all you need to do is download the stock firmware from sammobile.com or updato.com and flash with Odin (both sites have a flash guide I believe).
Make sure you flash all 4 files.
Yeah bro??☺ successfully downgraded without any issues.. camera ,battery is far better in Marshmallow?
Bro.. fingerprint sensor is not working?.. while dailing *#0*# in sensor fingerprint it says initialisation failed..
I don't use the sensor so I never tested it during my roll backs. You flashed all 4 firmware files? BL, CP, CSC and AP?
Yeah ive flashed all 4.... fingerprint sensor is working only in nougat frimware..?
I know the bootloader differs in N to MM which impacts a few things but if you flashed all 4 it should be fine, I would suggesting trying to wipe cache/davlik but an Odin flash should have been a full wipe already.
Yeah..bro.. i hve cme back to n ..bzo of this issue
Is fingerprint wrng fr u?.. in mm
I don't have MM at the moment, it's been a couple months since I was doing my upgrades and roll backs
Hi all,
I need to downgrade a new g930fd (MFD 2018-01) as well to MM for xprivacy since I'm not one of the mass fools giving away all their accounts on their devices, everything on storage, phone numbers, IMEI, MAC address, etc. to every app that I need to run for my job, as well as every factory ROM and pre-installed app. Oh, I forgot to mention every app talking to like 5 or more mobile app tracking servers including graph.facebook.com!
Anyhow, I ran into the fingerprint sensor issue as well with downgrading to MM. It seems to be something to do with the S7's with a newer manufacture date since I have other older g930fd's I was able to downgrade and have the fingerprint sensor work fine.
It appears to be that the driver in Samsung MM ROMs isn't compatible with the newer fingerprint chips.
This is the only difference I could find in the sensor information:
Working Downgraded to MM Fingerprint Sensor
Flex ID 2291
Product ID 144
Sensor ID 4099
Non Working Downgraded to MM Fingerprint Sensor
Flex ID 295
Product ID 144
Sensor ID 4103
I'm guessing the fingerprint sensor drivers included in S7 MM firmware don't support the "Sensor ID 4103" chips yet. All we would have to do is move over the drivers to MM with root, but I have no idea how to do this.
Can anyone with ROM building experience that's migrated drivers help out here please?
Thanks!
Update:
It appears the "Version" displayed in *#0*# under FingerPrint test is actually the driver version since there is a separate FwVersion displayed when you hit SensorInfo.
From a shell,
ls /sys/module
Shows the fingerprint sensor as a kernel driver. It's the Egis ET320 Sensor.
So, sadly, apparently you can not use MM with a newer hardware revision of the ET320.
The only option would be to either find an older phone maybe someone could figure out how to get the newer driver out of the newer Samsung builds so we can have an external kernel module in /lib/modules/<kernel version>/extra
Samsung source code is freely downloadable here if anyone could please compile the ET320 driver into an externally loadable module and instruct on overriding...
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=g930f
Swapping the sensor out with an older version will not work since the fingerprint sensor is paired with a chip on the logic board as many who have tried to replace their home button have regrettably learned.
Update2:
I downloaded Nougot and MM Sources from Samsung and see that the fingerprint drivers have definitely been modified. There is a makefile for building the fingerprint driver, but I have no idea what's all involved with getting this going.
Anyone?
Can anyone help a brother out here?
What's the right thing to do - try to attempt to get just the driver compiled into a module that could possibly override the kernel module driver (if it's supported) and drop it in /lib/modules/<version>/extra or recompile the entire kernel with the newer drivers and figure out how to install it?
Hello,
my p20 is already on 8.1.0 and was working well since I got it.
Now, the function for auto rotation is not doing it's work. Yes, it did work well before.
I was wondering, if anyone has the same problem and if there is a solution for it?
I tried to turn off ne knuckle features. It wasn't the solution.
Thanks
Have you tried Resetting your phone?

No, thought there could be another solution. But it doesn't seem so..
I have the same issue on P20 lite, after the update the sensors doesn't work anymore.
I have a locked bootloader and tryng to roolback with a previose version, with dload metod, but non easy to find the correct verson due a huge firmaware for P20
I contact even the customer support and only thing that said to me: "Please try with a reset or use you warranty to change it" (for me it's the second phone with the same problem)
Hi a few months ago I switched from global to eu after some time I wanted to update miui to a newer version but an error appeared (check ss) I've already installed a few twrp, including the latest and several recovery versions available on the forum (orangefox)
Can somebody help me?
Did you format data before installing?
Yes i did it
Maybe you can try a fresh install with a miui 12 fastboot rom .
@alibei I will try and speak up

Hello, I found a solution to my problem, so if we have a screen lock (pattern / fingerprint), you should turn off the lock in time, it is a security that "prevents" deleting data from our phone. I personally do not believe that such a screen lock is able to prevent theft of the phone with an unlocked bootloader but somehow it works, also the update installed, you can close the topic
