That's what I've recently encountered using the latest Marshmallow on my G920F. Fingerprint scanner had been working totally perfect until now. I tried various methods to get rid of the problem (but it still persists) such as: rebooting, wiping cache/dalvik, reflashing kernel, removing lock screen security and wiping Fingerprints app data/cache. Any tips or solutions? The phone neither fell on the ground nor got too hot so the hardware is perfectly fine. In the past the phone also couldn't connect to the fingerprint sensor once or twice but turning the screen off and on again solved the problem in every case. I could also try reflashig firmware (factory reset) but now I'm away from my computer (holiday) and would rather try to fix it on the phone itself as long as it's possible of course.

Carrying out a full firmware flash would be your 1st option as you've already tried a few things already, if that still doesn't work then it points to a hardware defect.

I have a Sprint Galaxy S5 and was running CM13 for a while without a hitch. Suddenly my auto rotate stopped working...I tried rebooting and doing a dalvik/cache wipe and SOMETIMES this would make it work again. It'll only work until my screen is off for a few minutes and then it no longer works. Apps that require landscape (like youtube) work just fine when going full screen but upon exiting the app stays in landscape until I quit (at which point the screen goes back to portrait) or if I lock then unlock my screen the app will rotate back to portrait.
So I figured this had to be a software issue. I tried a few other CM Roms with the same result. Then I tried flashing back to stock marshmallow directly from Sprint and NOT installing xposed or any system mods right away and it STILL happens! I can use apps to force the rotation but it doesn't work on its own. Again, sometimes after a reboot or a cache wipe it'll work until I turn off the screen then it's guaranteed not to again.
Can anyone offer some advice? Ive tried factory resets, diff Roms, diff hacks, nothing works.
Thanks in advance!

I'm having this issue, too. Has anyone found a solution?
It's almost certainly a hardware failure and therefore not fixable. My son's GS5's rotation sensor failed.
As a workaround, he installed an app that lets him manually change the screen to portrait or landscape mode.

Mine did that as well, but a wipe of cache and delvik cache worked.. I'm surprised that did not help for long..
So my S6 suddenly began showing "an error has occurred with the fingerprint fingerprint sensor. If this message appears repeatedly restart your device." when I click on fingerprints in the settings menu. I haven't dropped it or poured water on it. I've tried clearing data/cache in settings >application manager >fingerprints but the issue persists. I've not done a hard reset or reflashed the ROM cause I'm hoping there's another solution first. Dialing *#0*# to check the sensor isn't working for me cause for some strange reason my phone does not work with the secret Samsung codes. Device :G920F running stock MM with arter kernel. I would appreciate any help i can get
Have you tried to trigger secret codes with the App phone Info?
Use it with stock kernel and see any difference.
Charged phone during long flight, and read a lot. After landing, fingerprint sensor was like 50%. Reboot, no improvement. Menu for fingerprint settings...click and lag, nothing. Reboot. Now fingerprint menu is gone. So is home button!
PITA....got Leedrod tweaks for Navbar! Dirty flash, and no fp sensor. Clean flash, no fp sensor. Restore stock system and wipe data...doesn't even ask for fingerprint on setup. It's like the hardware disappeared. Tried force stop fingerprint software from settings, apps, show system, and clear data. Reboot again...gone.
Wakeup next day, reboot and it works? So flash Leedroid, and restore my Nandroid data...all good now.
So what can cause the loss of the hardware like this? Some kind of security lockout? Or hardware fault? Didn't get wet. Still in 30 day period...should I send it back?
Has there been a software update from htc for the fingerprint sensor?. Things usually go mental when updates occur..

No changes from my end regarding software. I guess it's possible something got corrupted with flashing and stuff. Seems to be a common problem on other devices:
https://forums.oneplus.net/threads/...vailable-issue-started-out-of-nowhere.450914/
They describe same situation as me. Hardware just disappears, and the related menus.
Thought mine was fixed, but it happened again last night. I let battery fully drain, then fully charged, rebooted, and it's back again? I did walk around in the rain last night...could be related.
Wish I knew if this was software or hardware issue. Guess only way to know would be to RUU.
Another weird thing: I have to enter a pin now when phone boots up. Not on the lock screen, but on a separate system prompt. Same thing when I start TWRP. Could be a security issue? Or a conflict in PIN settings?
Any help appreciated!
There's already a thread about this https://forum.xda-developers.com/u11/help/home-button-fingerprint-sensor-stopped-t3632297 this is no hallucination, I experienced it myself, and also a lot of One Plus 5, LG G5 and G6 owners. Seems to be a hardware implementation issue. Maybe same FP scanner manufacturer ?
Hey there,
for about two weeks now I am noticing this strange issue: When I want to unlock my phone I touch the finger print scanner, the capacitive buttons light up but it takes sometimes more than a second before the screen lights up.
I am on Android Oreo, TWRP, S-on, stock firmware, magisk. This setup worked perfectly for many weeks now. I already cleared the cache partition.
Rebooting helps for a short while.
Does anybody have the same issue or has suggestions how to solve this or an idea what the cause might be?
Thanks a lot in advance!
Do you have a live wallpaper or an app that interferes with the lockscreen?
No and no.
I stumbled across another thing: using SD Maid improves the situation for a short while. Cleaning up the data bases seems to do the trick - for a half day or so...
Hey all,
I experience problems with the fingerprint sensor. It often doesn't recognize my finger on the first try but I need to try it several times before my finger is recognized. Or face unlock solves the issue and thus the finger print problem is avoided. I also deleted the finger print and set it up new several times but the problem persists.
Anybody else got the same problem?

Nope, my fingerprint sensor works perfectly fine.
Yours may be defective.
Take off the case from the phone. Make sure u scan ur finger correct.
If is not helping factory reset.
If is not helping call oneplus...open return due defective hardware
This finger print sensor reads much differently than what I am used to. For me it's literally a quick tap with my finger. If I hold like I would with Nexus 6p it won't read.

The sensor is really quite small and not perfect. I scanned the same finger three times (different parts of the tip) and now it works quite well. You will get occasional errors stating that the same finger has been scanned already, but if you keep trying it works
It's not a perfect sensor or even close, I've had to add a finger twice to get it to unlock properly most of the time. I add it as a new finger.

I bought the OnePlus 6 and I came from the OnePlus 3 and I ran into a similar issue. It helps if you input your fingerprint multiple times
For me its not that it doesn't recognize the finger, but sometimes it just doesn't even recognize that I have placed my finger on the sensor to check if it's mine. I have no idea why this happens
Mine works great. Sometimes I think it's even too sensitive, I turn the phone off and it comes back on when my finger is still in the vicinity of the sensor. Try to wipe it off with some mild water-dishwasher solution to get any dust/body oils off of it.

Are you running a custom kernel? I had this issue on Stock OS using Flash Kernel. Reflashing back to stock fixed it for me
My fingerprint recognition was always failing. The sensor was working because it would vibrate whenever I put my finger on the sensor but it never recognized it. I contacted OnePlus Support and the first thing they recommended is to see if there was an upgrade available. There was one - so I upgraded - not really thinking it would help at all. But miraculously, after the upgrade, fingerprint recognition works like a champ.
Try upgrading.

For me I had this same issue but not initially. The first 4 days I ran into zero issues. It worked every time. I then decided to start tinkering and installed the XXX mod. It wasn't quite what I was looking for so I decided to return to stock. At this point I flashed the stock rom via phone update menu. Then I factory reset and set up again. I noticed memory management issues and also problems with my fingerprint reader not recognizing my finger as easily. Re doing them didn't help. So I thought maybe I would use the fastboot method of restoring the software like the Nexus/Pixel roms. I did that and it flashed successfully but had the same issues. So I decided to manually flash each partition on both slots. Then I set up again. Still had issues. I figured at this point it was definitely a hardware issue because I felt I couldn't be any closer to a stock, out of the factory condition. But I was wrong. The msm tool that uses the Qualcomm drivers is the "Factory Image" I was looking for. It completely restored my phone to the condition it was when I unboxed it. I know logically there shouldn't be a difference but it flashed or fixed something on a certain partition that got changed when I was tinkering(I assume). So long story short. Try the msm tool if you think you have hardware issues before you rule out the software.
Fix-Fingerprint sensor not responsive
Entered to safe mode fixed the issue for me after a lot of trying to make it responsive.
Go into battery /battery optimization /hit the... Menu (advanced optimization) uncheck advanced optimization.
If on she is saving battery in sleep mode.
The issue you guys are describing is simular on rear sensors.
I did the above and it helped. Give it a try.
