Fingerprint scanner fails to recognise my finger - Galaxy S6 Q&A, Help & Troubleshooting

Hello
I have been using my s6 from 6 months now. but this past month i have started having issues with the fingerprint scanner.
i have my right thumb registered 2 times in 2 different angles
my left thumb twice in 2 angles.
but despite of that my fingerprint shows no match. sometimes it detects my finger sometimes it doesnt.
I know my backup password and i can always log in using that. but i just want to fix this fingerprint issue. it is so irritating.
i used s5 for a year but never suffered such an issue.
and yes i have tried to re register the prints while deleting old ones, and even tried factory resetting but this issue persists.
please help me. and i do not have warranty coverage as my phone is international

Finger print issue not accurate

Does anyone have problem with the finger print?
Mine is not really accurate, most of the time if my finger is not on a correct angle/position, it won't recognize at all even if just a slightly off.
I have tried the fix on MIUI forum using the *#*#6484#*#* but still the same.
Is this a common issue with Mi Note 3?
Add finger twice and move it when it is scanning.

So this is a common issue?
I already did what you suggested and it may be a temporary fix for now but still kinda disappointed.

I have often temporary problems with fingerprint on any phone when my hand is wet, especially after washing dishes or working with something wet for a while, etc.
Accuracy of fingerprints depend on the fingerprint data that you registered. 10 samples are actually to low, but more won't be user friendly. So make a good use of that 10 chances by registering your finger on different angles that you might use when opening the device.

Fingerprint scanner works poorly?

Anyone else have to continuously rescan their fingers every day just to get working fingerprint scanner?
It's getting ridiculous.
I have each of my index fingers scanned 3 times ince the last update!

I've not had this problem. It's been very reliable for me.

Try using more pressure when you register fingers. May help.
I'm thinking you just need to scan in more orientation?
For example, LG asked you to scan one side of your fingertip, then the other, then another, etcm OnePlus it doesn't seem to matter where you scan the graphic always fills in the same way.
I don't know. This tiny half sized fingerprint scanner is getting on my nerves. Otherwise the phone is nearly perfect. Except for Fingerprint & YouTube defaulting to 480p on every video.

But I think I scanned the prints better. I guess we'll see if they last for 24hrs.

I had the same issue on my OnePlus 3 and it is a very simple fix. Go back into where you register a fingerprint and register your fingerprint one or two more times and the problem will be solved.
Press on the sensor from all angles trying to cover each possible part of to your fingerprint even the tips when registering

Doesn't allow duplicate registration on 6

I face this same issue as well. Re-added both fingers multiple times to cover more of the 'print', but it still doesn't always recognize them. Although it seems to work a little better when you press less hard on the scanner when you try to unlock the phone.

I registered the same finger twice by ignoring the messages that pop up. The accuracy now is close to flawless.
The error is because it already has that part of the fingerprint stored in the original fingerprint record. The reason you got it to ignore your 2nd attempt to register the same print is because it's picking up the part of that fingerprint that wasn't recorded on the first attempt. By doing this you are certain there isn't a spot that registers a print that got missed making your scanner much much more consistent.
I just switched from Pixel XL to OP 6. The fingerprint sensor is a lot faster but slightly less accurate than on the Pixel - sometimes you don't register a fingerprint if you position a finger way off.
Having said that, I have used the phone for about 1 day now, and I have learned the fingerprint sensor position. Now it works perfectly for me 100% of the time (using with an original OP silicone case.)
If you are having problems, your hardware may be defective. Replace the phone.

It won't let me even trying to ignore messages.
Edit: Figured it out. I understand now.
The trick is to scan different parts of the same finger.
On fingerprint 1, I scanned the top part of my index finger.
On fingerprint 2, I scanned towards the bottom section.
Ignore the messages that come up when scanning fingerprint 2 and just persist with registering.

Fingerprint sensor - discussion

Hello,
I’m using the Xperia 5 since this Wednesday (for two days).
My overall experience with phone is mostly good (for most parts of using even perfect). Unfortunately, these nice words do not apply for the fingerprint sensor.
It usually takes 2-5 tries to unlock the phone, sometimes I can’t even open the phone with the fingerprint scanner at all. (The error messages are: Not recognized; could not process fingerprint, please try again. Sometimes it says something with "partial fingerprint").
I tried rebooting recalibrating the fingerprint with the wizard then rebooting again. Nothing seems to help. I know this doesn’t have to be eventually a defect or something. Fyi, my thumb is not moist or oily, same thing applies for the reader. Maybe my thumb is just too wide, I don’t know.
What’s your overall experience?
Jakub
Same experience. Worst fingerprint reader I've used.
Same here, IMHO the worst fingerprint sensor I've ever used on a device.

I got it working but putting my finger along the side of it and not by using the thumb having the finger pointing out from the phone.
Mine works almost every time now.
But it is indeed not the best scanner.

So, you didn't use Z5 series. That was the worst fingerprint sensor. Fingerprint sensor didn't work more than it worked. This one on 5 is better but not good. Sometimes it doesn't work at all.
I have the same issue as well, as do many others evident from Sony Forums however the FPS works fine Banking apps, website logins etc

I didn't use a Sony phone with fingerprint sensor before
I am kinda used to finger print sensor being 99,99% accurate and reliable (iPad, Meizu, Nokia, LG, Samsung, Asus, Xiaomi etc.) so that's why I am surprised it can implemented so poorly. :silly:
Honestly after 2 weeks with this phone, I'm beginning to question whether it has a fingerprint scanner at all. Feel like I may as well just remove my fingerprints and forget it exists.

I sold mine last week, of same reasons. Useless fp, might as well be non existent.
I had to retrain myself with how to use the finger print scanner. With other phones, I'm used to using the tip of my finger, but that doesn't work with this scanner. As HellRoot describes above, I now lay the flat part of my finger against the scanner so that my finger is parallel to the phone (not pointing at an angle). Now I can get it to work very reliably.

Sadly not working for me at all.
Not to mention I encountered "flip case" bug when the phone is refusing to accept touch screen input to take a call.
This "Sony experience" is much more frustrating than I ever expected and that comes from a guy that used LG V30 for 2 years.
If they do not fix software issues with Android 10 update, I will seriously give it to my mom or wife and buy a propper phone.
My FP sensor worked perfectly for two weeks, I did not get a single "Partial FP detected" and was wondering what's with the bad press.
Then, gradually over the course of a day, it's started playing up. Now I'm in line with everyone else, frustrating experience at less than 20% hit rate. Android 9 or 10 doesn't seem to make a difference, tried factory resetting etc.
Checking the Service Menu (*#*#7378423#*#* from the Dialler --> Service Tests --> Fingerprint Test) returns the following:
Fingerprint Sensor Status:
Sensor not OK
Sensor HWID:
0x0603
I can't seem to find more information on this error code, contacting Sony has returned the typical "Are you running the latest software?" and "Have you tried restarting your device?"

I just got mine yesterday, pretty much everything work perfectly except for the fingerprint, and mine also show the same Service Tests info as yours.
When I scan my finger, it usually register only at certain angle, and usually only at my 2nd press on the scanner, which is quite frustrating
I really wonder if this is a software bug or hardware problem so I can have the store replace a new one.

I just raised it on the Xperia Support Forum, fingers crossed it gets enough traction for Sony to look into it!

But seriously they do not mind to use not so reliable devices. Xperia 5 is still an upgrade for Xiaomi Note 4 or Asus M1 Pro user.

It appears to be Software. I have issues only with unlocking the screen. The Banking apps seem to work fine (for now)

That's good to hear. I suspect so too because the service tests show everything was fine when I first bought the phone (it was running Pie at the time) and I started upgrading to Q soon afterward. And it was the 2nd day after I upgraded to Q that I notice the service test "Not OK" info.
Hope it can be fixed in the near future update and off topic: hope that update will also include patch for third party launcher to work with Q's Gesture (my most annoyed thing about Q)
Edit: After a few days using it, I realize it recognize the finger really well at certain angles. It never scans well with full finger but almost never miss when I use my finger tip or side. So I guess I can live with it for now. But still hope for improvement soon.
Well, other Xperias like XZ2, XZ3, XZP just got updated to 10 recently. And, all I've seen so far are complaints about 2 things: no swipe gesture (because the stock launcher hasn't been updated, which is rather stupid) and fingerprint on those devices all become less responsive. It took many times pressing to work, which sounds just like our problem.
So I guess this is a software based problem from Sony's side. Maybe some bad fingerprint driver I guess. Anyway, hope Sony is aware of this and get it fix soon with December security update (also hope for third party launcher patch too)

Odd fingerprint issue...

I got a newish Note 10 plus, so I add my fingerprint and it works very well, first try, almost everytime, works wonderfully.... when i first add it... Slowly over the courses or 2-5 days it starts having a harder time recognizing it, untill it finally just wont recognized it at ALL. No screenportector and no other issues. What could be causing this what could I do to try and fix it?(Getting a new finger is not a possibility, I already looked into it)

Were you able to get it working properly?
Btw. from my experience, there are people who are not able to use fingerprint scanners. Unfortunately. For instance - my mother got an Ipad some years ago. Fingerprint worked for 1-2 days, then it stopped. She was not able to unlock with her finger anymore. New scanned fingerprint worked again fine for 1-2 days... Now she has Dell laptop with fingerprint scanner. Same issue. I tried to scan her finger on my Note 10. Same issue, it worked only for a few days..

General Most Idiots way to make use of P6a slow FP

Well, I'm on A13 Beta 4.1
I have noticed FP is not consistent at all..
For some, it's unlocking after many tries or can't even register FP..
At first i thought it was an issue in A12 where FP is registering Thumb expression but unable to unlock fast enough (No. I haven't noticed but where my P6a can be unlocked with unregistered Finger)
After moving to A13 Beta 4.1 it got worst..
Just now I have noticed that FP is working completely fine when your Finger is little wet.. Yes, you read it right..
At first even I was confused but then after some searching and applying logic, i gotta know that If your registered finger is Dry, I won't be able to read it properly so Titan M2 chip just refuse to accept it..
But Once you made your finger little wet(Little saliva or less than drop of water which is enough to make your finger wet enough), It just unlock it in 1st try..
I tried it for around 2 days.. So yes, If you are having trouble unlocking your P6a, Just make your registered finger little wet & unlock it..
Before we start complaining about M2 Chip, we need to acknowledge that all phones which don't comes with security like M2 chip just unlock device instantly because they don't have additional security like M2 chip...
Sorry for bad Englis...
yeah I'm noticing the same thing... and you're right that the moisture (or oil) level in my finger matters. Sometimes I can unlock my phone easily and sometimes it just can't read my fingerprint at all. When that happens, I try to re-register and I would repeatedly get "can't read your fingerprint" errors. Even tried removing my screen protector, but same issue.
Started noticing it when I took a trip to a dry/hot city. Started noticing repeated fingerprint errors.
In fairness though, any amount of moisture on my finger resulted in my 3a XL not recognizing it.
I do definitely prefer the physical sensor though vs the under screen solution.
Odd thing is that I'm back home now where it's not as humid or hot or dry and suddenly having numerous issues with my fingerprint. I'm on Android 13 beta 4 and fingerprint was fine for 4 days or so. Tried re-registering FP today and I kept on having sensor registration issues as well as FP reading errors - repeatedly.
In fact, I didn't have much issues with the FP since I got the 6a a week ago (when I was on Android 12 and then switched to Android 13 beta 4), so not sure what changed. Going to switch back to Android 12 and see if that makes a difference.
FP is also hit or miss for me. I'm on Android 12 and actually I couldn't register my fingerprint few times when I bought the phone. In the end, after some reboots and setting all the apps up I managed to register my fingerprints but now sometimes they are scanned without issues and pretty fast, but also sometimes I get info that fingerprint is not recognized and I have to put my pin.
Im guessing most of these issues will be fixed with software updates. It seems this device may have been a bit rushed to market. This is typical new device stuff though.
