Fingerprint doesn't work so good

Hi, I have just bought my new S7 and setup my fingerprint on it.
I didn't have fingerprint on my old phone so I can't compare it but I find it really inaccurate..
It gives me alot of wrongs if I am not landing my finger perfectly centered and sometimes even when it is, its still wrong..
I have tried to reassign fingerprints which does improve it for that couple of minutes but later on when I grab my phone and try to unlock it I get so many wrongs..
Is it just me? or any one else find it frustrating?
Any tips to improve it?
Thanks.

Mine never has issues, if your hands are clean and not prone to being sweaty then I would exchange it.

Unlike naturally how we expect it to work or how the other sensors like iPhone's, Nexus 6p's etc. works, with Galaxy S7 you should be careful when registering the fingerprint because of the relatively small surface area of the sensor. To make it clear, you can cover almost the whole finger print (considering the relatively large rounded shape of the sensor) in various other devices. While in the case of S7 you should only register the fingerprint in the way your finger will naturally positioned when unlocking. In my case considering the thumb, only an edge of the thumb will only get in contact with the sensor not the the center part or the other areas of the print. So just register the print in the way you normally hold and unlock the phone not keeping in a flat area and registering. If this works there is nothing wrong with the sensor. Otherwise you gonna need to replace the unit.
PS: Correct me if I'm wrong @cadcamaro ;-P

try registering same finger 2 or 3 times, this helps a lot increasing the accuracy of the scanner.
tip and sides of the finger is very important when registering

I personally set up my thumb when my phone is in my hand already, I also make sure that I move my thumb around and read as much of it as possible.

Thanks for all of your tips!!
I don't think my sensor is defected, it works after all..
I'll try the trick for registering only the tip of the thumb which indeed is what usually presses the button.. in fact I did register that part but not only that..
And about the register more than one time the same finger, does this thing actually recommended?
I mean its kinda ruin the machine learning of that thing.. it gets 2 different fingers that looks alike isn't it?

For me, using the thumb only works if I use/register the center of the thumb. The tip never works, but I can live with that. Center always works

works perfectly for me. in comparison to my S6's finger print sensor, this one is 10x better - faster to recognize and unlock and much more accurate.

Onscreen fingerprint reliability

Hi
I’ve had my vivo nex s for over 2 weeks and found the onscreen fingerprint unreliable. At times it works perfectly and then at times very fustrating it doesn’t work at all.
I’ve noticed when it’s warm or I’m outside, not sure why.
I’ve reset my fingerprints added couple of times for the same finger but that doesn’t help. I’ve noticed when phone is heated it’s less reliable and doesn’t work at times.
Not sure if it’s faulty or that’s the experience of most out there
Please share your experience and do you think I’ve got faulty set.

Absolutely no problems with the fingerprintscanner.
I've double registered my fingers and it's working perfectly.
Sometimes it takes 1 second but in 99% its working nearly Instant.

Perfect!!! And with a screen protectors or tempered glass? Co.okie4u you have a private message!!!

I also have my moments with the fingerprint scanner. The elite X3 scanner was more a hit than a miss compared to this phone. I will say the it has improved with the 16.5 update but it needs more work. It's as if the registered fingerprint file gets lost.

Yes, double registering your fingers does the trick. Works flawlessly over here.

How you double register your fingers? Each finger for twice saving? Thanks

I have registered my thumb 3 times and im around 75% when i hit the fingerprint reader.
My main problem asides from the 75% is that its a very small spot on the screen and that i often dont touch it 100%. That, combined with the 75% reliability, means im lucky if im at 50%

As i said absolutely no problem with the fp scanner.
Even when only my half thumb lays on the spot. I think it's a registration problem. ¯\_(ツ)_/¯

May be but you have registered 5 fingers? In each save one finger? Or 1 finger for 2 saves
Please Co.okie4 you have an unread private message since 2 days from me, can you read it? Thanks

I have the same finger registered three times. How I managed to do that is place the finger not on the entire scanner but place the finger on part of the scanner to where you can still see the scanner light. Also use the edges of your finger on partial scanner. I kept trying and it worked. My misses are now less. This shouldn't be the solution as it should just work, but that's one way to get around the problem.

No problem for me.
The only issue is its a little slow when compared to generic finger print, but the awe u get by people around is totally worth than extra second.

Just be aware that you have to follow the instructions as stated on the screen. Use the pressure you would use as usual and when you are registering the edges of your finger grab your phone as you would in real life and with the same pressure as you would use.
I found that if you do this too lightly or too hard you will not recreate it in daily life and hence the failure.
Also register the edge side of the finger that you would touch the screen with, not the entire edge left and right

What is the best methods you find to improve the Success Rate of Fingerprint Scanner

So yes just lets admit it, The fingerprint scanner on Vivo Nex is not perfect, but what it represent is forward thinking which will force other manufactures to follow, but we all know that Optic under glass fingerprint scanner will have to make room to the far superior ultrasonic technology.
despite this I am interesting to know what method you people are using to get higher success rate ?
The first question that comes to mind does it really help to save multiple fingerprints for the same finger ?
Even though I mostly my thumb to unlock where it is hit and miss the index finger have a lot higher success rate, and I wonder why.
Dry hands seem to be a big problem for the fingerprint scanner... I therefor tried to save a new fingerprinting when my finger are dry, I cant say it any visible improvement. It is still frustrating that my index finger seem to work a lot better on the fingerprint scanner.
Fingerprint scanner seem to work better in dark room rather then a well lit room or environment.
please posts your findings how to improve success rate especially for using the thumbs.
I think there is still hope that the fingerprint scanner will improve further in future software updates.
I also think, people will have a different success rate because of biological versions, some fingers are maybe harder to read then others for some reason. Lets hope Vivo will push out more updates for the fingerprint accuracy. This is their first device aimed for the global market so lets hope they will give this one extra care since this device will be the bridge into the global market..

I use multiple fingerprints for one finger and think it's much more reliable than one saved fingerprint.
Interesting that my index fingers are also working much better with only one saved profile instead of my right thumb
Vivo Nex S is recognizing your already saved fingerprints. Nevertheless you can simply save the same fingerprint again by moving and trying different positions from your finger. I actually saved my right thumb three times and surprised how good it works (for the first 3 days)

Actually 2 months now I’m very pleased by reliability accuracy and smoothness of 3D underscreen fingerprint scanner.

Thanks..I thought that had been tried in youtube videos I think I saw people say its does not help to make multiple fingerprints for the same finger... it should not be needed..it should be smarter then that..
especially since you press the finger multiple times when you setup a new fingerprint.
Well anyway I will try it..I guess it can be worse then what it is now....
Its frustrating that the index finger works so well..and not the thumbs...

I saw some review where they said that someone unlocked their smartphone with an unregistered finger...
This fingerprint sensor is really not reliable at all
And funny, i asked Vivo on facebook about this issue, Joe just told me "use a password instead" ...

To be honest I don't trust any videos about finger print scanner. If somebody wants to troll all they have to do is register the finger and state on the video that finger is unregistered and just troll the Vivo Nex owners about how unreliable the phone finger print scanner is.
I tried several times to unlock the phone with any finger that is unregistered and 100% of the time the phone doesn't unlock and send me to unlocked the phone with the pin number.
And the finger print scanner works 98% of the time with me on my registered fingers, I noticed the other 2% is because my fingers are wet or dirty from working out.

I scanned my thumbs fingerprints and it works better with the left one. Even after a rescan of the right one
I didn't succeed in making a second scan with a finger already stored
Of course I don't know why

The accuracy is fine,however there is another interesting notice-you don't actually have to wait with your finger on the screen until the phone unlocks. You can simply put the finger for a second,release it and then wait a bit more for the unlock. That's quite intersting user experience and it makes the visibility of a faster finger recognition process than it actually is

I am sorry but I do not believe in this method...
Remember when you create a fingerprint you scan your finger multiple of times even from the edges etc.
Theoretically it could only lead to even slower scanning.
Anyway success rate have improved a lot the last 2 days not sure why...
Hopefully its learning and getting better for each day. I still hope vivo will solve the speed.
one frustrating thing is the screen dont unluck directly even when the scanner have read your finger for instance I cant put off my finger before it gets unlocked and it unlock...
I hope next update will come with some improvements regarding fingerprint scanner cause I think it does not live up fully to its potential right now.

It seems that the unlocking process is actually quite fast. There is a delay because of the animation. If you turn off animations in developer's options unlocking would be faster.

Enable double tab to wake screen
Then
Double tab screen
Use fingerprint
This make it ultra fast anf accurate

Always find my right hand not working fine with fingerprint??

Make sure the position you scan your finger is in the same position you unlock ur phone, I found this to work 8-9 times out of 10

what I have learned lately is, its good to not push too hard on the screen push very gentlely it seem to be easier to unlock. anyway I think this scanner still need software updates to improve it have problems in well lit scenarios, luckily I am a night bird..

Yes I can confirm push the on screen scanner gently always works brilliantly,in few scenarios I pushed it harder didn’t response some time with first attempt.
Overall experience 2.5 months I’m very pleased with accuracy,response and smoothness as long we learn his trick.
Always helpful if someone experience not so good response or accuracy to register 1 more time from beginning it’s finger and tested one day continuously until been successfully.
And repeat 1-2 times to find their best performance to his own way.

I just played with the fingerprint yesterday and I feel that it works better when we press harder I added the fingerprint in the dark, with a minimal backlight pressing the finger firmly.
I sorry for my English, I use Google Translator.

Fingerprint scanner has been updated with latest funtouch software , Rescan your fingers, you will definitely see and feel an improvement ?

Do you mean the global or the chinese rom ? I use the chinese rom, I think nothing was mentioned about fingerprint scanner improvements in either of the latest firmwares of global and chinese. Anyway I will try rescan my fingers I have nothing to lose.

Fingerprint sensor - anyone else finding it extremely bad?

I'm trying to find out if my device is faulty as the finger print sensor is extremely inconsistent.
Previously capacitive finger print sensors I've used have pretty much been flawless unless your finger was dirty or wet, but I'm getting far too many failures to unlock the Fold2. I'm either greeted with "No match", "Cover the entire sensor" or "Wipe the finger print sensor" messages. It's very temperamental - I can click the button to turn the screen and keep my finger in place and it will give me "No match", if I slightly raise my finger off the button and rest it back on the sensor with my finger in place it will unlock....
I have registered this finger (index on right hand) 4 times in the settings. I can test my fingers in the biometrics section of the app and it seems to register a print every time so it looks like it's an issue with how the sensor works when actually unlocking the phone.

Works fine here, but disabled it. The placement is ridiculous!
/CK

Same thing for me, works fine in apps and elsewhere but unlocking the screen is as frustrating as hell..... had the same issue with the S10e but hoped they had improved things. On research (since the S10e) I believe this only affects certain types of people like me with certain types of skin/fingerprint characteristics. Rear fingerprint scanners are no issue for me at all, it's just side mount !!

It took some getting used to but I like it now. I do wish they where up higher.

I noticed that the way I hold the phone and the placement of the sensor had me using the side of my index and thumb rather than the center of either. I put both in again while being careful to use the side rather center of my finger and it works fine now. Another thing that's a little of a push is that you can set it to always hot which helps. The push part comes in because you can trigger it enough while simply holding the phone that you'll max your attempts accidentally and have to put in your password.

Works fine for me, but as others say, the placement is awful. Holding the closed phone in your hand the way you normally would and you touch the sensor causing the 5 attempted unlocks to kick in so I often end up needing to use pattern unlock.

Works much faster than the Z Flip. But the placement is terrible.

I am not sure they could have placed it anywhere else.
An in-screen one on the front wouldn't be helpful when you are using the inner screen, and one on the back would be very awkward with the phone open, especially as the inner screen is probably used equally in both portrait and landscape. Certainly wouldn't expect one on the inner screen anyway, the technology is not up to that yet.
But compared to my Note 20 Ultra, the fingerprint reader on the Fold 2 is far more reliable and quicker in my experience.
As someone else said here, the trick is to register your thumb predominantly and scan the edges of your thumb. Note how you hold your phone and use the sensor naturally and use that part of your thumb or finger when registering your prints. And register more than one set using the same finger or thumb.

Flawless for me

It's a million times better than the S20 series!

Much better than the Flip.

Works perfectly for me. Better than my Note 10+ did. I like a physical button much better than in-screen. That being said, my N20U fingerprint scanner also works better than the N10+. I have small hands so that might also help. I don't think the placement would be that good for my Husband's large hands though...

Works fine for me!

its fine for me. i had to set it for a few fingers though based on the diff ways of holding it

OG Fold user here and it's absolutely awful and inconsistent for me. Easily the worst scanner I've ever used in a phone.

My problem is locating it on the side of the phone if there was some sort of indentation or something to better locate it, I think it would work better.

I find it pretty reliable to the point that I can unlock it without trying based on how I reach for my phone in my pocket. I also find it mostly well-placed when holding it with the main screen open and using it for apps or to unlock the phone.

Question Touch screen sensitivity, finger print scanner | Adjustable? Will Google fix it?

I'm coming a OnePlus 9 and I'm noticing that the screen is far too sensitive on my P7P. For example, when I click on a notification banner, it thinks I'm long pressing and presents me with the options to "Silent," "Default," and "Priority" the banner notification. I've also noticed when I swipe left or right to go back, it will count it as double as the haptic feedback is felt twice.
I didn't know until after purchasing that Pixels were notorious for having bad finger print scanners. This one is worse that my OP9. I have a screen protector to put on still, perhaps it will make it just right at that point.

Well, the finger print scanner is even worse than on Oneplus Nord. And I also have accidental long presses. I am actually quite disappointed with the phone.
One more thing that I dislike is how the navigation buttons have gaps between them. I constantly tap on those gaps and nothing happens. And if you use gestures, swiping to go back conflicts with swiping to open the side menu in apps.

I was hoping that this device was going to keep me happier than my OP9, oh well. it's still an early release. Hopefully it gets better with firmware upgrades. OP has gone down hill and that's why I'm here. If this fails, I'm going to submit to iOS (wait, did I just say that?!)
I did just put a screen protector on. I'm hoping that will kill some of the sensitivity. I went with the Milomdoi from Amazon. It was the best out of the 3 or 4 I ordered (sent back the ones I didn't did like). Installed pretty easy... despit the one small dust spec I missed in the far right corner. It'll be OK. The case almost covers it up. I'll report back if the screen protector improves the touch at all. I not hopeful though haha

You both might have some bad displays, my fingerprint scanner is far better and faster on the Pixel 7 pro than my OnePlus 9 Pro. I don't recall any issue with the touch sensitivity so far.

On a same note, could someone please tell me if this is normal: https://giphy.com/gifs/COEoRqIfJdhpWTxoKC
When I adjust the brightness and leave the touch input for a bit, the slider goes all over the place. It's pretty annoying and doesn't seem that the slider should act this way.

The reason you didn't notice is that like almost everyone, you don't let your finger linger on the slider, but slide it to where you want it and let go

Now tap and hold is too long when on medium. Why wouldn't they have this adjustable in ms instead of three preset options.

The fingerprint reader has been perfect for me (so much better than on the 6 Pro) but I agree about the screen sensitivity. It's too sensitive.

Absolutely zero issues with the fingerprint reader here, I find it just as reliable and even quicker than my S21 Ultra and that is with a protector.
I suggest it's either a bad screen protector install (air bubbles around the fingerprint area would cause havoc with it) or maybe it's just not a good protector for use with an optical scanner.
