Fingerprint sensor has stopped working - Samsung Galaxy S8+ Questions & Answers

My phone showed a message saying "make sure finger is dry" so i tried rebooting and removing my fingerprint but now i cant add another as it has the same message. I've also noticed theirs a small chip in the sensor does anyone have any solutions?
Thanks

Have a rooted phone, restore from backup. From your post I'm getting that the finger print gadget was working before?
If it does not work then, with an OS where, for certain it was working before, the sensor may have been mux'ed.

In reply to this question from a year ago - I have exactly the same problem on a refurbished S8 I bought recently (small chip in the sensor). It's a very long shot, but I don't suppose you sold your phone and I might have it? I bought it from Handtec (in the UK). Does your phone number start with 07376?

Fingerprint scanner not working!

So just now my fingerprint scanner stopped working.
It was fine an hour ago and now it won't recognize my finger. I have to unlock it with the passcode.
I've tried adding a new finger and when it asks to press my finger down, I do so and will lift it off to put it on again but it will say lift your finger for like 4 - 5 seconds as if it doesn't realize I took my finger off until 4 - 5 seconds later.
I've done a reboot a few times and same thing. I really don't want to do a hard reset but might be my next step.
Anyone else experiencing this? Or have suggestions?

Mine just started doing this tonight. I have no idea what's causing it, but I really don't wanna do a hard reset.
It's the weirdest thing, and really bothering me since it's a security feature.....
I'm still holding off for now but if I can fix it by the end of tonight I will do a hard reset.
If THAT doesn't work I'll be marching right into Tmobile tomorrow first thing and won't be leaving without a brand new phone!
Did a factory reset.
I was able to add a new fingerprint but there is now a huge delay before unlocking the phone.
F**king pissing me off. $600+ phone giving me crap like this.
Replacing tomorrow
Can't add another fingerprint now. I get this error, can anyone point me in the right dorection?
Galaxy s6 fingerprint not working
After initial set up of my Galaxy S6 my fingerprint worked briefly then failed to match since. Deleted the fingerprint and added three different fingers prints and still no resolve. I returned the first phone to T Mobile and they exchanged for a second device. Exactly the same issue. Since the phone is so new, not alot of posts are made addressing this issue. Will be calling Samsung next. If anyone has a fix, please post.
Damn sorry to hear. Tmobile overnighting a new one today. Hopefully my new one doesn't have this issue, I'm ALMOST tempted to return completely if this is going to be a issue. This is BS
Same issue with mine!!
I'm returning this phone now
Funny thing mine was having the same issue and it's starting to work again. Still slow but will unlock, not sure what is going on
Which version are you using? As I know, there was an update on Friday lastweek.

Hey a friend just told me he got the same problem
just that he doesnt remmber the pin code
any idea what to do?
I have started to develop this issue since today morning. I have the latest update from Samsung too. It works once in a while but this is not good enough. Not sure whether to return the phone over this.
UPDATE - I deleted the existing finger prints and then redone them again. It works but only at a certain angle and not as efficiently as it was the last couple of days.

I had the same issue. After tinkering around for a bit, the scanner seems to function fine when power saving mode is turned off. YMMV.
Mine is doing the same thing. I don't think this is a hardware issue though so you probably won't see much difference with getting a new phone or a hard reset even. At this point it's wait until a patch / new firmware is released that resolves the issue or play around with the settings to if something is conflicting with the scanner process.
While I do not have the non recognition issue, it is definitely very slow to unlock. Sometimes takes a full 2-3 second to register and unlock. Can even scan the finger pull it off and will take a couple seconds to unlock, so it seems more of a processing/software issue.
Mine has now developed this issue as well. Was hit or miss for about a day, now it doesn't work at all. In fact, if I press the power botton and the lock screen comes on for a second or so and now unlocks itself. I've tried adding new fingerprints and messing around with the settings, but nothing seems to work. I noticed when looking at the list of fingerprints, one would periodically flash blue. I went in to add a new fingerprint and before I could even start, I noticed a fingerprint starting to register. So I sat and watched and sure enough, an entire fingerprint would go through and register without me placing a finger on the key. I tried cleaning the home key thinking it could be reading a dirty or left over print, but no such luck. Bad deal here. I love this phone, but whatever this issue is is complete garbage. It's almost like its registering its own prints...
Just curious. If you're having these issues is your phone rooted and or do you have apps frozen/removed. Thanks
I'm running pure stock...including TW
I was just under my 14 days so I went ahead and returned my s6 this morning. Sprint gave me a new unit that I haven't had time to test out, but hoping this issue isn't going to plague these devices. I'll update if there are further issues.
Same issue here. Really frustrating!

[Q] Fingerprint sensor

I have my device unlocked, not coded - european version. It was all good no problems with anything.
Just last night i went to sleep and when I woke up in the morning I noticed this error on my S6:
"An error has occurred with the fingerprint sensor. if this message appears repeatedly, restart your device."
Clearing cache did not help. Nor dit the factory reset...
Tried running fingerprint test by typing *#0*# on the phone app but it stopped with no result so I guess there must be something wrong with the fingerpring scanner.
Honestly I am very dissapointed and must admit that i would not expect one of the major funcionalities to stop working after less than 48 hours from buying.
Anyone else having this?

I've just started getting this too. Mine is 11 days old. Did you figure out if it is a hardware or software problem?

Kind of.
Apparently some of the SGS6 units are faulty and have loose home button or not well clipped or anyhow you describe it.
So its a hardware problem. They should repair it by replacing the front screen, glass and home button or just give you another phone.
Give it to the warranty.
Today I am very dissapointed in SGS6, would not buy it another time. It is not that spectacular at all.
Better wait for Note 5 or choose another brand.

Thanks for the info. Must say, I share your view. The phone looks nice but thats about the best thing I can say about it at the minute!
I'll speak to Samsung in the morning and see what they say.
Sometimes it happens to me too but its very rare and I just have to unlock the phone via password and then the sensor restarts working. I dont think (hope) its a hardware issue.
Well mine is not working for a month now. Not a single time. So its hardware believe me.
I will give it to warranty when possible.
Yours apparently is software issue, or even hardware but not that serious.
I spoke with samsung and was told it is a known issue that they can deal with under warranty. Fortunately mine presented quick enough that I'm getting a replacement from EE.
I had the same issue of sporadically not working. Replaced the phone (warranty). Have the exact same issue on the new phone. Guess I'll exchange yet again. Very frustrating.

Fingerprint Scanner Does Not Work [Clean&Dry Msg]

Ever since i got my T Mobile Galaxy S6 Delivered a couple of days ago, the finger print scanner does not work.
It keep displaying the message :
"Make sure that the home key is clean and dry, then try again"
Here is a video of the problem: https://vid.me/aHjp
I bought the phone on Swappa, and the seller claims it never got wet.
I've tried searching for similar issues but have no found anything like it... any thoughts?
I just did a hard reset and still the same issue.
Anyone with any insight please?
Make sure there isn't a protective strip on the button. Peel it off. Had one like that, felt the fool...
It's probably on the way to not working. Mine said that a few times and now always gives me the fingerprint sensor error message.
Hard reset hasn't fixed it.
It's a common issue. Happened to me as well, now it's not working

So what is Samsung doing about it? Can we all submit complaints to them in a common place so they do something.
Should I send it in as a warranty repair?

I would. I switched to an iphone 6s+ and i'm sending my S6 to Samsung for work. The fingerprint sensor stopped working and it has a serious hardware issue with the wifi. I only hope they don't blame their **** product's problems on the crack in the back glass.
So my fingerprint scanner started working ...out of no where.
I ran the test under #*0#*
And it says failed... but it works. For now
Weird
it happened again
tip : when I put my finger on home screen , the message vanishes as it read my fingerprint
it's a software issue after updating my fw
now what?
Samsung galaxy note 5 fingerprint scanner not working after factory reset
I also got the same issue. Everything was working fine and i factory reset the phone to clear storage space. After the reset when i tried to set my fingerprint the scanner stopped working and started giving the same dry and clean message. I have realized that the phone doesn't even tries to read the fingerprint and anyways gives the clean and dry message even if i don't touch my finger on the sensor. I think that Samsung is doing this on purpose. I think that we all should get together in this forum and we should try to contact Samsung about this issue. The have to do something about. Thanks

Fingerprint sensor bricked after mainboard change

Hi guys.
I have an S7 border and my mainboard phone is dead. I bought another mainboard from a phone with the broken screen. Replaces the mainboard and everything worked perfectly except the fingerprint sensor. Does the firmware kernel fingerprint sensor driver on the new motherboard is incompatible with my fingerprint sensor hardware? I have the sensor that came in the phone that I bought, but it is of another color and I would have to remove the display to replace the sensor, with a high risk of breaking the screen. Do you think it's possible to be kernel incompatibility? Any guidance? The error is: "An error has occurred with the Fingerprint Sensor. If this message appears repeatedly, restart your device." I already removed the firmware for andoid stock 7 and 8 but did not solve this problem.
Please, somebody knows something about this?
Anybody can help me?

Did you make sure everything is plugged in properly? You could try plugging in the home button /fingerprint sensor from the phone you bought and just leave it hanging out for testing purposes just to make sure it's the actual sensor or just something not plugged in properly.

P30 fingerprint picture showing up often

When my P30 is placed on the table (I don't notice when in my pocket, duh ) it lights up the "Place finger here" in the bottom.
Does anyone have an idea why that happens?
It's not like the table is moving or anything to trigger a read, so why is it showing?
Could it result in burn-in?
I have same problem, it could result in burning, but i have no idea why it shows up
It is annoying! I've turned it off in favor of a PIN to prevent burn-in
I wrote and email to Huawei and the replied rhat IT shouldnt result in burn-in.
And if I didn't want to risk it, I could turnering it off.
Not really a valid answer...

I'm surprised their IT is not aware of the latest OTA from last night, which is version 9.1.0.124(C431E3R2P2) and fixed the problem. The annoying fingerprint symbol no longer randomly appears but only if I move my phone (and in the pocket it would not show as the proximity sensor prevents that from happening, which I have tested).

That didn't solve it for me. It still shows up.
I still use the screen protector that was on the phone when I bought it. Did you remove yours?

I've kept it on. Normally I'm not the kind of guy who uses one, but this was placed on very well I still find the screen to be excellent, it does not bother me. Have you immediately pulled yours off or can you describe a before/after experience?

I just tested at my desk and it came up 9 times in a minute.
I still have the protector on. Never removed it as it is placed nicely.

Is that the standard P30 you have on .124? My P30 is on .113.
I have this issue too, the symbol shows up several times a minute. I have seen others mention elsewhere that this could well be a hardware issue?
I'd just assumed this was a software issue but if it is hardware then it may be time to return it?

Yes, it's standard version... After I bought it (first day), phone was updated with this version ...
After I switch off the phone (and put it on the table), symbol shows up for a few seconds, then disappear until I move the phone ..
Maybe you should try first with .124 version .. ?
Hi
My p30 is on 115 update and still has the same problem
Anyone try without or with a different screen protector?
I have found some kind of solution, but by some reason it does not work all the time. Settings- Smart assistance- Shortcuts & gestures - wake screen - Double-tap screen to wake. Activate that option and reboot the device.
But as I can see, that light might be used as some kind of notification light since it blinks when there is something, like e-mail, message and other things that need attention. When there is no internet connection it is not blinking until you move it.
All of the above are just my personal observations and I don't insist that they are 100% correct.
Having this act as a notification indicator isn't a bad theory, although the frequency of it appearing seems wrong for that kind of use.
Personally, I'm bummed at the lack of notification light, something I had been relying on for years with all my previous phones. I might end up taking advantage of the OLED screen and just make it keep the screen on instead.
My phone updated from 111 to 121 today (I guess we have different build numbers in North America), I still see it flashing from time to time while it sits on my desk.
Update: I tried with a tempered glass screen protector and now it doesn't show up unannounced anymore.
I think it is an issue with sensitivity of the screen.
