Earlier today I was mucking about and decided to play around with the fingerprint scanner for the first time. When I went in to settings and clicked the fingerprint manager, I received an error stating that the scanner is borked, and to reset my device to fix it. Rebooting did not fix the issue.
Soon I found another person with the same issue, who said that he was able to fix it by flashing stock NJ7 via Odin. After a bit of chatter we realized that neither he nor I had set up the fingerprint scanner before flashing a ROM. We basically booted the phone and went straight to rooting it, and flashing ROMs on it.
I can confirm that re-flashing the stock ROM via odin allowed me to set up the scanner successfully, and that the functionality has not been affected by any subsequent ROM flashing.
I do not understand the mechanism behind why this happens, it is just my experience. Perhaps there is some sort of validation that is run the first time you use the scanner, making sure you are running official firmware, and then setting a flag somewhere? How then would that flag be saved for all subsequent rom flashes? Hidden partition or some ****? Hardware flag? I dunno I don't get it, but I figured out how to fix it by golly. Hopefully this helps someone else.
If any others can confirm the same issue, we may want to add this as a step in the rooting/romming how-to threads, so that others don't run into the same issue.
One good thing is that when I flashed stock via odin, it didn't wipe my data. I was able to then flash TWRP and then Dynamic Kat again, keeping all of my settings the whole way through. Ended up not being as much of a hassle as I thought it was going to be :good:
Thank you for sharing this, I have to say in my case it is not working now i did get the phone rooted and then added jovys rom then did my setup the fingerprint scanner worked for me, then i installed dynamic rom and then the later update of same rom and then the fingerprint scanner is no longer working for me there is a new update for the rom i am going to flash and see if it works now as in a previous version the bloat from samsu g had been removed and with jovys rom being stock rooted it was still there, so i am wondering if it has to do with some of the bloat from Samsung and it being removed that breaks the fingerprint scanner, i will report after i flash the new version of dynamic.

I first noticed the problem while I was on Dynamic Kat 1.1 and thought the same thing, that it was something to do with the Sammy apps, but it still didn't work after updating to DK 1.2. I've had it both working and non-working whilst running the same ROM (1.2,) and the only thing different between the two instances was the fact that I configured it while I was in stock in one instance.
This is important information. Hopefully the devs will be able to fix this asap. Thanks!!
Wow thank you BotsOne! I'm having the same issue. I'll try this in the morning. Before I rooted, I set up the fingerprint scanner and it worked fine the I switched back to swipe, then rooted. After rooting I installed Jovys rom and lo it hasn't worked since. Does the lock screen have to be set to fingerprint scanner at the time of flashing roms or can you set it up once and move on from that point forward? Thanks again!

Honestly I'm not sure. We need a few more people with the same error to get to the bottom of what's going on here. I could be way off with my assumption. We need a bit more info.

Yes, I am quoting the entire op...
Give me some more evidence of this and I will edit the Root & Recovery Guide immediately... I have seen conflicting posts on this matter too... Also, is not clear if private mode does continue to work after rooting or not... Can anyone confirm... (without flashing any roms... from original unrooted to rooted) Private mode... does work or not??? (Private mode is not suppose to work after rooting... but some say it does work???)
Nice post! Come on people... help...
Before you back up your rom, disable fingerprint scanner and delete saved fingerprints. If you don't and you go do your backup and ever plan on using the scanner again on that backup, it won't work. One of the guys thinks it has to do with the fingerprints being encrypted so when you restore, it can't decrypt it and locks you out.
I can confirm personally that disabling it before you do your backup then flashing a new rom then restoring your old backup, the fingerprint scanner will still work. Just have to set it up again. But that is a whole lot easier then flashing stock with odin again and starting over.

I think this may be an additional problem for flashers, but not necessarily the same one I am addressing. The reason I say this is because I hadn't configured the scanner at all previous to when I discovered that mine didn't work, the error completely prevents me from opening the fingerprint manager. I couldn't even enable the fingerprint function to begin with. Does that make sense?
Not trying to argue just trying to make sure we are on the same page =)
Just noticed my fingerprint scanner isn't working. Wtf lol

Thats not entirely accurate.
I set up my stock rom with the FP scanner...backed up in twrp as usual and i have flashed 4 roms since then and had to set it up gain each time and never had a problem. Ive never disabled it once.

I can tell you my history. I setup the fingerprint scanner right away before flashing anything as it is a must have feature for me. Later, I flashed a couple different ROM's and never had an issue. Just had to setup the fingerprint again. So my guess is if you set it up before flashing any ROM, you should be good. At least I was. I haven't had to disable before flashing or anything like that.

I'm currently running kennethpenns 2.3.4 beta 3 GB rom, and at first the fingerprint sensor worked flawlessly, now it never works. Even after I reboot, the sensor doesnt work.
Not quite sure what thee problem could be. The only mods I've installed are the battery fix and the 1% mod. Anyone else experiencing this problem? I'm considering just doing a fresh install of 2.3.4 using either kennethpenns or cherryblur
Sent from my ATRIX on kennethpenn's GB 4.5.91 using xda app
I have the same issue. It started happening after I flashed Kholk's kernel which messed up my wifi. Since then, I have tried changing kernels and such, to no avail.

Yeah, but not a fingerprint data restore though. Only apps. I just did a factory reset and the fingerprint sensor won't even scan when I try to add the security lock now

No new kernels at all. Flashed the kennethpenn's 2.3.4 radio, though that was a few weeks before the fingerprint sensor just completely stopped working.
Also, seems like the lock pattern no longer wants to work as well. I just set a pattern lock, fresh install of 2.3.4, and sometimes when I unlock it'll ask for it, and sometimes it won't.
There has to be something wrong here. Maybe it was the enable wake on volume mod? Though thats not installed now on my fresh install of 2.3.4
I really hate double posting, but does anyone have a solution for this? Should I just go to att and get a replacement?
Finger print scan fix
this should fix it. go in and set your pin code. reboot the phone. now go back in and set up your fingerprints.
I had my phone on 1.83 and used the bootloader unlock, root, then a modification to the SQL to get unknown sources avail. I had to use RSD and an sbf for 1.8.3 in order to get the ota to GB to install correctly. after that i factory reset my phone just to be sure. when i was setting it up i had this issue. the above got it working.
Unfortunately that didnt fix it. Whatever the issue is, is deep in the system data because flashing new roms doesnt fix the problem.

pure stock, after OTA gingerbread my fingerprint reader stopped working entirely as well.
Don't care as I don't use it, but irritating to know, I was actually hoping it would improve performance so I would actualyl start using it.
I had the same issue after installing 2.3.4 and read somewhere that turning off your phone, removing the battery for a couple minutes and putting it back would fix it. It did fix it in my case.

Stock bell 2.2.2 stopped working now..
my fingerprint scanner stopped working...tried to restart, remove batt, change the diff types of lock options...no successs. any suggestions?
Yeah this issue is really annoying. I'd hate to have to go through the whole process of getting a replacement. Its crazy that both the fingerprint sensor won't work, and the pin code lock won't work either.
Bump Bump Bump
This worked for me also. Stock with 2.3.4 OTA update. Set up a pin. Then chose the fingerprint sensor option. Thanks!
So I've been searching all the internet regarding my problem and found none to have my problem.
I was using popwiz rom and after a while my fingerprint sensor stopped working with the error "An error has occureed with the fingerprint sensor. If this message appears repeatedly, restart your device."
Because I needed my G900FQ, I ignored the issue for a while. Found S7 insanity which has a fingerprint bug and forgot about the problem.
Yesterday wanted to check out official MM for my S5, and had to reflash stock lollipop. Then I remembered my fingerprint problem so I tried to set it up. I kept getting that nasty error, tried deleting cache, tried deleting data with Titanium. Reflashed stock 2 times again, nothing worked. Until I was ready to give up and go to bed. Then it suddenly started working. Managed to set it up and activate fingerprint unlock.
Now is the bummer!
I CAN UNLOCK with fingerprint if waiting about 3 seconds after turning screen on.
I CANNOT ADD FINGER through settings, I get the nasty error message.
Tried to enter factory tests and under NormalScan button says Version 0.0.0.0 and in SensorInfo says Ready and stays that way.
I tried to enter factory tests very fast after unlocking with fingerprint and I got, only once and for a brief moment, the right Version and SensorInfo, and Normal Scan showed data and graph.
Now I will try to install official MM firmware with Odin.
Anyone has any ideas to what the cause may be ? And maybe a solution ?
Thanks in advance
L.E. I installed official MM firmware and now fingerprint sensor works when unlocking and adding fingers, but when I try to unlock my phone while it is connected to a power source I get the nasty error message again and prompts me for my backup password. Any advice would be deeply appreciated.
Flash a stock ROM and factory reset?
It seems you did not read the whole thread before suggesting me this...
I did that many times. Lollipop and MM official stock... Its like the sensor is not responding in some situations , but in other situations it does. And this seems to be pretty random..

It seems you don't even know what you typed, nowhere in your OP did you mention factory resetting and then flashing a stock ROM
Only that you flashed stock ROMs, flashing stock ROMs does nothing to reset anything and will leave behind bugs from the previous ROM if the issue is with an app / data etc
Before getting clever, read what you type
It's obvious that by flashing a stock rom over a custom one will leave bugs. Did full wipe (system, data, cache&dalvik, even phone internal sd) before flashing stock, every time. Thanks anyway..

Well maybe next time add that fairly important info to your main post, instead of hoping everyone is psychic, and then throwing a hissy fit when they suggest something you have not stated you already tried.
I have followed the guide to flash the unlocked firmware and root my S7 Edge (http://forum.xda-developers.com/ver...de-flashing-sm-935u-firmware-verizon-t3415145) and all has been working well this weekend. This morning my phone gives me a persistent popup notification about a service provider update and "my device will restart to configure features supported by new sim card." The only option is to press ok and allow it to reboot. I cannot use my phone while this notification is active, and I am unable to kill it in any way. When the phone reboots to recovery, the configuration fails with "dm-verity verification failed". I then reboot system or power off and the endless cycle continues.
Has this happened to anyone else, has anyone figured out a way around this? I think I can reflash the firmware and start over from scratch, but this is of course not ideal.
Thank you for any help you may provide.
I wasn't getting any notifications however i did have some strange behavior going on and rebooted only to get the dm-verity verification failed and was no longer able to boot it would just sit at the Samsung splash screen I then had to factory reset re-post and re-setup everything, hopefully your experience won't need that since you are still able to boot!

Thank you for the response, it's always nice to know someone has had similar problems. Looks like I will have to try reflashing the firmware. After your re-setup, did you do anything to prevent the issue from reoccurring?
Everything is again in working order. If anyone finds this and has the same problem, after flashing the Verizon fixes the phone is identified (in the about device setting) as the SM-G935V version again and is set to download updates automatically. I unchecked this option and I hope this should prevent it from happening again.
Not really wasn't sure exactly what happened the first time but thankfully (knock on wood) ??? it hasn't happened again.

Going to have to disagree with you there, I have had DVFS disabled since I've rooted and have never seen this issue. I should say though that I'm on the international firmware, so maybe it's something with the Verizon firmware?

This has been my experience, as well as a few others. I'm not 100% sure it's that setting in particular, but I am 100% sure that it is caused by a setting in xTouchWiz. I had the issue once before, and it was a clean install save for xTouchwiz and me running through all the options. Since then, I've limited the choices in xTouchwiz and have not experienced the issue since. When I have some time I'll run through it and see if I can replicate the behavior again, since I'm working on a ROM.
There is a simple fix...
I agree, XtouchWiz drops a bomb when installed and it will cripple your phone. I never played with DVFS, I personally though it was the disable TIMA that set it off. An easy fix for anyone who stumbled on this. Power off your phone, remove the sim card, power up your phone, freeze a service called AutoPreconfig, power down and insert sim, good to go.

Maybe I could get some help, long shot but maybe. I have been flashing roms for quite awhile, on 5+ phones to be exact. I can get EVERYTHING to work and run perfect except fingerprint only worked on first custom ROM flash, now none work. At all. When I try to add a fingerprint, It brings up the fingerprint image on screen and even reacts to me pressing but it will not register a fingerprint. No errors like, "partial fingerprint" or "Fingerprint not recognized" nor any confirmation. I've fastbooted back to several versions of OOS(9.0.11,9.0.12,etc.) on both partitions and tried and tried. Nothing. It still works 100% on stock. The weird part about custom now is when it tells me to setup a fingerprint, it says its located on the back of the phone but I remember my first custom flash said it was on screen.
I know the support is still new for custom with FP but nobody seems to be commenting these issues. Is it normal for right now?
Any support appreciated!

Did you solve your problem?
Which custom rom are you trying?
Did you flash the stock rom from the fastboot Rom Zip with the flash_all.bat way?
Before you flash a custom rom you should check the features lists/search the thread.
Most devs post in the OP if fingerprint works or not. And 9/10 the question has been asked and answered in the thread a few times.
I've done the flash_all_partitons.bat to go to complete stock. And nah it's not fixed, just living without it for now. I'm on luisroms RR build. I've tried I think just about all of them, no go.
And I have checked features and comments, why I'm posting here in questions, not in rom threads. All custom roms support FOD fingerprints now. Just not my phone it seems.
Weirdly TWRP can't decrypt my data on custom roms at all even though they support it. Thinking something the fastboot flashes don't touch is messed up somehow. Idk
I am having the same issue on the current Candy ROM. Screen flashes as if capturing a fingerprint but never does. FP is supported according to the dev and no one that I saw had this issue in the ROM thread. FP reader did work with OMNI and stock, of course. Thanks in advance for any help!

Sucks no one responded to your post. I rooted my sons S7 Edge and sometime after it acquired the same issue yours has/has. I had another S7 Edge phone so I ended up rooting that one and giving it to him. I still have his old one with the camera fail issue but I've yet to try to figure out what caused it to happen. I know my response doesn't help with info or duration from OP post to reply, I just wanted to let you know that your post wasn't ignored by everyone.

So I ended up putting that phone back to stock then rooting it again and it had the exact same issue yours has. I did a clean root too and the issue is still present. From there I decided to again run it back to stock and this time do a nand erase all and repartition the device. After all was finished I checked the device and I'll be goddamned... it still has the same issue. So if the problem persists after all that reformatting is it safe to say that it's a hardware issue? I'm out of ideas. Sorry I couldn't help you.

you guys offer little information at all so this is why no one helps you. Maybe tell what firmware version you flashed what root version you did etc. There is a big difference between bootloader revB/11 and the others
Holy ****. Did I just get constructive suggestions from jrkruse?! Dude if you told me I could fix my phone by sucking a fart out of a wallaby's ass I'd do it cuz the advice came from you, and if there's one thing I know it's that you know your ****. You're ****in' awesome. I feel so special now. Ok sorry about that...
Well, I'm not too sure about the OP but I can tell you about the phone I have that seems to have the same issue.
My S7 Edge is a SM-G935V on android 7.0 on update 4BQK2. Prior to rooting I put everything to stock then I did a NAND erase and repartition. No issues with any of that.
I rooted my phone from this post

I AM NOT RESPONSIBLE FOR ANY OF YOUR ISSUES! ALL I CAN DO IS RECOMMEND A GOOD PSYCHOLOGIST! Hey guys. Stumbled on this by accident. I HAVE ABSOLUTELY NO IDEA WHY IT WORKS, BUT IT DOES. THE METHOD HAS BEEN TESTED BY ME AND A FEW OTHER PEOPLE HERE...

which directs to your older method for gaining root privileges.

I also flashed Unzip the Nougat_S7_Root_2_82_All_Carriers_V2.
Then I flashed the BL file in the BL slot from the G935U firmware with odin checking "Phone Bootloader Update". I used the BL file from G935UUES4BRA1 since it's the closest update for the U brand to the firmware this phone is on (G935VVRU4BQK2)
I'm aware that there are newer methods for gaining root access but I chose this method cuz I used it back in 2017-2018, I had read all the posts in the thread, and I knew it worked.
I currently have 3 S7 Edge phones all on the same firmware and build and are all rooted with the same combo method I just explained. The other 2 phones also have xposed installed and they both work well.. expect mine says weird stuff instead of the callers information. I think it only does it if they're a contact but in the notification tab it says an example like this 5556661234;verstat=No-TN-Validation. No clue how to fix that.
The phone that is having the same issue as the OP still had access to the private/secure folder when it was rooted; which I thought was weird cuz mine doesn't and from what I understood private mode gets disabled if the phone's rooted. Maybe it only gets disabled if you install xposed? I don't know. My son had the phone with the issue and it was his first smart phone and he dropped it a few times (with a case) so I was thinking it's an effect from something he downloaded from the play store (he's 20 now but pretty still very ignorant with android). Now I'm not sure if it's a software or hardware issue since the problem persisted after the NAND erase.
Something to note about my sons old phone also is that it has 2 thin pink lines running down one side of the screen (defective/dead pixels) and when the screen turns off it it flashes once before actually turning off. One time over the phone I tried troubleshooting the issue with him and he ended up being able to use his camera immediately after rebooting the phone though once he exited the camera app it wouldn't open again. We were trying a bunch of things, force closing any app I thought would be related to the issue. Not sure what allowed it work when it did, but even now right after a reboot the camera app still crashes.
This was long ago, I've since lost the phone. But, I was on the A bootloader and on OREO rooted using @/billa's method using an ENGboot file. I tried everything possible to get the camera to work including flashing back to stock but nothing helped. I just gave up finally. @kanesglove maybe try safely updating the firmware. Hope it helps
