Looking for tips that may help in troubleshooting fingerprint scanner. Currently getting the Attention an error has occurred with the fingerprint sensor. if this message appears repeatedly restart your phone. restarting phone does not fix the issue clearing the cache and data does not fix the issue. currently running optimal ROM 15-5 on OD5 bootloader. have also tried to flash NCG and still does not fix the issue. I usually figure stuff out but this one is giving me a help and any help would be appreciated.
thanks in advance!!

The fingerprint scanner has stopped working suddenly. i tried clearing the data and reflashing the stock rom. if you know how to fix it please help
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.
friendz my samsung grand camera not working it giving error like can't connect to camera so tried to force stop and cleared cache and also deleted cache partition from recovery and rooted also and installed cm13 6.0 to it but still getting error like can't connect to camera ,so suggest me some tricks,
Try removing battery for 10 seconds then put it back in, see if it works. If not, try reflashing a firmware
i tried reflashing it but giving me same errror..

This error appeared randomly or you had any issues flashing? Maybe you dropped it and caused hardware damage?
If it's a software issue, refreshing to your stock rom should fix it so if you have already tried that it is probably a hardware related issue.
Well pulling out the battery trick worked for me and my two friends with the same camera problem, I suggest it to others as will, please try it before going to the extreme of flashing firmware.
thank you guys it really helped me, I found that its hardaware issue and i solved now my phone's camera working fine ,thank you. once again,,
Hi,
When I try to register my fingerprint it says continuously fingerprint hardware not available,
Now, I know that my fingerprint sensor is working beacause it was woking ok but I wanted to add more fingerprints to make it more accurate, and when I tried that it kept saying that hardware not... So I deleted all the exisiting fingerprint and now I cant register any.
Did wipe cache partition and tried to clear data from com.ztefingerprints.service but it's greyed out.
I want to avoid factory reset, or clearing the phone data.
Any solution?
Edit: stock b32
Thanks
Which rom, dirty flash the ROM !
Stock b32
I'm with g model on custom rom, just reflash the ROM from sdcard, your data should stay.
Hi, which version are your phone in, A2017 or A2017U? Seems same problem with my phone......Have you tried flash your phone?
A2017U stock b32, not custom rom.
What do mean flash my phone, can I do that with stock rom?
Will it delete all my data?
I hade that problem before I ota update to b32, and still have it..
Thanks for your answer！ You can back up your personal data to your phone'account，then try to factory reset.
I am having issues with the fingerprint sensor reading my finger but I was able to add a new finger.
Thank u guys,
I've found a fix!
For some reason "don't keep activities" on developer mode was "on", turn it "off" fixed the issue.
Glad to hear that, good luck!
Thanks for the tip, I had the same problem, but thanks to you it is solved.
I just started having an accelerometer issue. Suddenly my device started vibrating and turning the flash light on and off. Turns out the accelerometer was triggering the flashlight gesture. It is also screwing up my ability to use my camera because it thinks my phone orientation keeps changing. The only fix that I have found online is to do a factory reset but I am running TWRP and Nougat flashable stock build from here: https://forum.xda-developers.com/g5-plus/development/twrp-flashable-stock-builds-t3813351
I have tried flashing a backup I have from a couple months ago but that didn't help. Any advice on how to proceed is greatly appreciated. I do want to move up to Oreo but haven't taken the plunge yet because I need to research the issues with IMEI disappearing or something to that effect. I will do some research and maybe try to re-flash the Nougat stock build that I am running and see if that helps, after I backup all data.
Fixed it. Downloaded the build i was using and flashed it and it resolved the accelerometer issue.
