So I flashed lineageOs 17.1 unofficial build on my phone earlier to test it out. After booting into it, I realized the fingerprint sensor wasn't working so I flashed the stock rom using odin. After boot, fingerprint sensor still didn't respond and when I try to add a print, I get an error,"make sure the home key is clean and dry, then try again.", so I used the dailer code (*#0*#) to run sensor diagnostics. The results are as seen attached. Is there anything I can do about it? The home button still works fine so I doubt its a hardware problem. If anyone has a fix for this i'd be grateful for you to share.

I've had my phone for a few months now
I flashed the Skydragon 6.0.1 ROM yesterday and I wanted to move back to 5.1.1
So I did, I flashed the TWRP for 5.1.1 and I flashed the Stock OOS 2.2.0
But now, my home button works and Im able to register my fingerprint but after I selected use fingerprint to unlock it doesn't unlock
I've tried every solution on the Internet such as
1) Force stop com.oneplus.fingerprint and hard reset
2)Use software nav buttons
3)Factory reset
Nothing seems to work
I love the fingerprint feature in the OP2
Someone please help me out.
When I dialled *#808# and checked the finger print auto test and it said PASS
So Im sure its not a Hardware error
You should probably flash the old modem back. Can you please get into the security settings inside settings and tell me if you have a force close. If you get a force close you have to flash the old modem.
By saying modem I mean firmware. You can find it in OnePlus 2 Android development > taker18's cyanpop's second post.
Or in blissmallow thread second post.

I have the exact opposite issue. My FPS works with all ROMs except H2OS 6.0.1. Let me know if you find a solution. Might help me fix my problem.

Thanks guy, I fixed the problem by flashing a persist.img
Hi.
I've been looking for similar problem here but I've found nothing.
Here's my situation.
Stock rom
Unlocked bootloader, changed recovery to TWRP
Backed up stock rom, flashed CM13
*CM13 apps are crappy* Backed up CM13 and restored stock rom.
Current status: fingerprint sensor freaks out. I've came up to this in camera app as soon as it started to take billions of selfies (idiotic feature of taking picture by fingerprint sensor). Then checked if I can set finger pattern - not at all, ZUK started to take thousands of patterns and vibrating all the time. It's hard to explain, but it seems that sensor stucks in a loop that scan fingerprint and somehow founds it (even if ZUK is lying down untouched).
Best of all is that, when I restore CM13, sensor does fine as new, so it can't be strictly hardware issue, drivers perhaps?
The fact is I don't really need fingerprint scanner and best solution would be disabling it.
Any ideas how to do this? Or what really happened and how to restore its functionality?

You can try to delete /data/system/users/0/fpdata/user.db and /data/system/0/users/settings_fingerprint.xml. Then reboot.
Another possibility is to reflash stock rom, not restore backup!
I have also been through the same situation. Restoring the COS 12.1 will freak out the Fingerprint scanner and camera issue as well. The best option is to flash the Stock ROM COS 12.1.
Happened to me aswell.
I did this:

You can't downgrade android version via backup because each Android version needs different firmware files so if you want to roll back from mm to lollipop you must flash the needed firmware files, you can do that flashing cos12.1 via twrp or fastboot.

So I installed the revolution mod (nougat) and my fingerprint sensor was not working so I installed the stock firmware and because there were no fingerprints saved on stock, I factory reseted the phone, then I installed the revolution rom again and it was working for few days but now it stopped working again (sometimes it does not recognize it and sometimes it doesnt even vibrate... Like i would not even have my finger on it)
Hi guys,
Recently, I have installed Arrow OS 9.0 and I was unable to enroll my fingerprint (But I can use my fp sensor as home button).
Currently I have flashed stock ROM and restored IMEI. I was able to use both my SIM slots and device name shows xt1643. Again, I was not able to enroll my fingerprint. The error message reads "INTERNAL ERROR, Sorry your fingerprint can not be enrolled due to internal error". But, after rooting my device i was able to use it as home button.
Is there any thing that i have missed? Or is my fp sensor gone?

Thankyou brother for the info. But even after reverting back to stock rom, my fp sensor was not working properly. Maybe some of my vendor files were messed up.

yesterday i install ED7GE rom v8.0, fingeprints work perfectly, after backup rom and want to install v9.0 the fingerprint shows 'Make Sure fingerprint sensor is clean and dry, then try again'.
don't know what mistake i've done, i try to clean my sensor but nothings happen, i've try to flash stock rom too, but it keep me show the message. surely its not hardware broken right? cus when i restore ED7GE v8.0 i'd backup, fingerprint works perfectly.
i'm so frustrated. please help me
