Iris Scanner not Working - Samsung Galaxy Note 8 Questions and Answers

Hello, my name is Ade(yeah probably you already knew it from my nickname). I came from Indonesia, using SM-N950F csc XID. On dec patch, everything is working and seems stable. But not since january patch update
One thing that bothered me is Iris Scanner is not working. The scanning progress is running but around 80% suddenly got error(see the first screenshot).Once I using my irish before my screen broke and on dec patch its working. But a month pass and now my friend wanted to try iris scanner feature but got error. And start from that I realize that this issue. I tried factory reset and flash odin still error. Another issue is my auto brightness is not working. But face recognition is still working
My question:
1. Is this hardware issue or software?
2. Are face recognition and iris using same sensor?
3. Should I go to service center soon and claim the warranty?
Note: I never rooted my phone

Have you tried cleaning the scanner lens?

Try wiping the cache partition in Recovery Mode. If that doesn't work backup your device and perform a hard factory restore.

Thanks for the answer. I did the hard factory reset and it still did not work. So I contacted Samsung Brazil and they asked me to send the warranty. Maybe it's the motherboard problem.

Yes if you already reset and tried flashing with Odin then it's likely a hardware issue. Hope they sort it out for you

Camera focus working ONLY after a factory reset/firmware repair!

Hi guys,
First of all, sorry for my really bad use of the English language;
Second: I recently switched from a Nexus 6P to an E6553 (because...reasons), and I'm really feeling home with my new smartphone.
The only thing is driving me crazy is...the camera focus.
What's the problem? Simple: it doesn't work, I'm sure it's a software problem and I'll let you know why I think this.
Just after the Setup Wizard, the camera works, and works really really well (it shots awesome pics!). Focuses even little objects such as insects, without the littlest issue. An example is the first attachment: I shot that pic just after a factory reset.
But the problem comes when I restore my apps, my photos and then reboot the phone. Then, the focus literally DIES. No way to get it working, it just stucks. End.
The only way to get it working is...formatting the phone another time and then never reboot it again!
I tried a factory reset from setting, a software repair via Xperia Companion, I even tried to refash the stock ROM through Flashtool (which...simply stucks at "Writing data", and the only thing I can do is repairing the software with XC).
Nothing to do: the camera works flawlessly after a reset/repair/flash, but after a reboot it becomes unusable.
And focus isn't the only problem (as it was a little one ????) : opening the Video Mode in camera makes the device freeze, meanwhile using third party apps for the camera makes me see an huge amount of glitches. The strange thing is that everything works without issues until a reboot, so it's certainly a software bug, but I don't know related to what. And no, it's not an app or something I installed: focus doesn't works even when booting in Safe Mode or creating a new user from settings.
And no again, bootloader is not unlocked, it isn't even unlockable, so no DRM Keys fault.
What you suggest me to do? I really love that phone, but using it with this camera is just impossible.
Uh, last details: I'm on the latest firmware, 32.1.A.1.185, Customised IT (Italy). I tried to flash another firmware (CE1) but as I said before, it stucks on "Writing data".
Thanks in advance.
Today I'm going to send it in warranty for replace the camera. It will be back in a couple days, I'll let you know if the bug is solved.
I have focus problem too.
E6533, .185
unlocked bootloader--->flashed rootable kernel--->TWRP--->root--->flashed drm
After all those steps bootloader is now locked. Everything works fine except rear camera focus.

I managed to fix it! The bug doesn't appears if I skip the setup wizard and I log in my Google account in a second time. All is working well, and I performed a reset 3 days ago.
Yay!

I skipped the setup wizard (initial configuration) at the startup after the factory reset, then I added my Google Account opening Play Store.

Thank you for your solution. But it did not work for me. Maybe because my situation is different from yours. I unlocked the bootloader.

Fingerprint unlock issue... (Solved)

Hi all,
I had the VIE-L09C432B161 Firmware on my phone, everything was fine and the fingerprintreader worked perfect.
Because of a broken display it was repaired and as special "service" they flashed the B180 Version.
So far so good, but now I can`t unlock the screen or wake up the phone with the fingerprintreader.
Is there an issue with Fingerprint unlock/wake issue with B180?
Also when I try to download the B161 oder B173 from the Firmware Threads, I get errors.
It seems the URl has changed or Huawei removed the firmwares from there page.
Thanks!

The B180 works fine with fingerprint. U should send the phone back to service center because i think when they removed the back cover to fix your display didnt atach the flexcabel of the fingerprint sensor to the motherboard.

Thanks.
But I was not clear enough in my first post.
I can register Fingerprint and the Fingerprint reader also deny to register the same Fingerprint again and tell`s me that.
So the Fingerprintreader is working but not the screen unlock feature.

Ok, have u try factory reset the phone?
Sent from my VIE-L29 using XDA Labs
This was a really good hint!
I did`t execute the factory reset, however this remembered me that I removed some games and bloatware from the phone in the beginning.
Accidently I removed also an app called Tastatur-Sperre (Keyboard-Lock). The good thing is: it was in the recycler.
So reinstalled, reboot and TATA. It works again!
Puhhh, really without that I probably missed this change I made.
Lesson learned: Even if you have experience with rooting, removing bloatware and installing custom roms.
Don`t do it if you are sick! And I am sick....

Fingerprint Sensor Replaced, how to re-calibrate?

My p10 was just got back from warranty claim for broken screen. When i turn it on, there was this menu asking to recalibrate fingerprint sensor because the sensor was just replaced (not inputting new fingerprint). It was unclear how i should do it at first, however after few attempts it was supposedly asking me to rotate the phone while the finger resting on top of the sensor.
Too bad, i think my first few failed attempts may have miscalibrated the whole sensor.
Anyone knows how to get back into that menu?

I replaced a broken display on a P10 VTR-L29 and the fingerprint button is not working, everything else is. At first I though the display is faulty, but now I have doubts since the fingerprint option on the menu is just not there. I re-flashed the same version of the firmware (B369) via TWRP and the problem persists. I may have to try a factory reset.

So this is how it ends when noobs messing with phones they don´t understand.
-You can unlock bootloader by paying some bucks to DC phoenix.
When you have no fgingerprint sensor options enabled it points that:
- the fingerprint sensor is broken
- the fingerprint sensor is not conected right
Hi alll
I had the same problem after replacing my screen.
I used Quick tuneup, and since the fingerprint sensor work correctly.

Sorry bro, my fault, i thought you are the one who asked before you.
You didnt say anything about your problem just asked if there is a solution and that you cannot unlock bootloader. With this info no one is able to help you. But anyway:
1. method:
-Remove existing fingerprints
-do a factory reset
-add a new fingerprint (when finger not scaned properly try to push a little bit harder on the sensor and rotate the finger)
-After the new fingeprint is scaned it should work well
2. method:
-after you recieve OTA notification (every month) go to settings/system updates/ there are three dots in upper right corner and select "get the whole latest package". This will download the whole firmware and perform a factory reset low level and this should work (if simple factry reset didnt work for you).
if this methods don´t work i will suggest you to go to phone service.

Did you flash any ROM on it ? Maybe you tried to downgrade the device from Oreo ?
Today when I tried to find a solution to not installing OTA, I've flashed 7.1.1 as a downgrade. It failed, but after reboot my fingerprint sensor disappeared, too. Then after I reflashed Android 8 it appeared again.

When you did a factory reset did you restore from backup afterwards or set it up as a new phone? If you set it up as a new phone and it still didn't work then I'd say you probably need to contact Motorola and ask about getting it repaired.

i do have the same problem, no fingerprint option in security and the senser is not reacting on anything.
had fingerprints registered and working, but after the first october update the problem occurs.
When i flash back to los 15.1 build from 2018-09-26 the fingerprint sensor works again, option to configure reapears and all already registered prints are there.

My post was a little unclear, sorry. i am on los 15.1 and do have this issue on any build after 2018-09-26. i already opened up a regression on los jira bug/regression tracker (REGRESSION-2178), but since no one voted for it or seems to have this problem, i though it may be some step i took.
Anyway. in the meantime i tried to clear all fingerprints before flashing but it did not help
(i did not flash back to stock but to los)
I also did a complete factory reset, formatted data/ wiped everything and then did a fresh install of los 15.1 most recent build, but still got the problem.
I bet you still have a fingerprint file somewhere that needs removed..

@bcrichster: Thanks for pointing me in the right direction...
i flashed back to los 15.1 (2018-09-26), removed the fingerprintes and pin, flashed to the most recent version of los 15.1 but it did not work.
flashed the build LOS 15.1 (2018-10-30), then the menu was there and the sensor works!
So my question: where are the fingerprint files on the x4 stored... read about fingerprints and searched on the device, but did not find them...
Is there a difference between Slot A/B regarding the fingerprints?
Thanks
I had the same issue when I first flashed RR room. Ended up flashing back to stock then going through the whole custom ROM setup again. Fixed the sensor and all the other little issues I was having (no headphone sound, etc). Not sure what the underlying issue was but for the sensor, left over files makes sense.

Face unlock trouble on a fresh android 11 install

Hi ,
i just flashed the factory image for android 11 with full wipe ( was on last beta ).
My phone refuses to complete the face unlock configuration. Telling me that it can't add new face data and that i should remove one before retrying...
i'm rooted and i already tryed a magisk module supposed to fix face unlock but no luck
help please ? ^^

As of right now me and you are the only two that seem to have this issue.when I get home from work I'm going to go ahead and I'm actually going to relock my bootloader and and do everything and then I'm going to unlock it and see what happens.I can let you know in this thread if it works for me and that way you don't have to waste your time unlocking and relocking

I locked the bootloader then rebooted back into the boot loader and unlocked it and then flashed
Works for me too.
In past issues with face unlock, the fix was to perform a factory reset (Settings - System - Reset options - Erase all data) before flashing a new rom. Supposedly the chip that face data is stored is not cleared until you do a factory reset. Unsure if a full wipe clears the chip. You can try this next time ... may be easier than doing a bootloader lock/unlock.

Hi, My face unlock is also messed up after updating to Android 11 (it keeps saying “fit face into frame” without letting me register my ugly face...)
Did you encounter the problem after rooting? I’m trying to figure out how to solve this, as I had no success with factory reset or flashing OTAs and factory images

I had the exact same problem as you. face unlock became unreliable after the Android 11 upgrade, so I deleted face data and tried to set up again. It keeps saying 'fit face into frame' no matter the angle or the lighting. Did a factory reset and no improvement. I have never rooted or unlocked the bootloader on this phone. I informed google support and they are sending me a replacement.
Just to share an experience with the community: After android 11 update I was having glitches with face unlock. (Totally stock, no root & all latest ota) This got worse until it wouldn't work at all. Deleting face & starting over didn't work as it just refused to even acknowledge trying to register anything. Then the auto brightness starting flicking up and down and finally half the screen disappeared under green flickering. A factory hard reset made no difference. I even did it twice but the welcome screen on rebooting was still covered in green flickering. Searching for a new phone reluctantly. I picked up my pixel 4xl again to see if I could think of a way of selling it for any purpose & it was fine! Set up & reinstalled a backup & everything including face unlock works perfectly like new. What was all that about!?
Can you describe full algorithm for noob, please?

I dunno what's the situation of you guys
But let me share my experience
I was having lock screen lags in Android 11
So I flashed the previous Android 10 image
It broke the face unlock and still broken even after flashing the full Android 11 image with wipe
What I did was flashing back to Android 10 again
Then update to Android 11 through OTA
This also was the method in r beta to fix face unlock issues

This is a known problem, and so far Google has not fixed it. Unsure if they ever will.
