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.

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.

Terrible fingerpring reader

The fingerprint reader on my Note 10+ is terrible!
It often doesn't recognise 4 or 5 attempts in a row, then locking me out from further biometrical login and I have to use my PIN to get into my phone.
I was kind of expecting for this forum to be full of this problem. Is it only me then?

Update to Official Android 10 , and re-write your review after doing that ! :good:
Also look arround for threads regarding some tricks to get a "beter" fingerprint registration

I am on Android 10 already.
It already starts when registering a fingerprint. It constantly says "Press a little harder" when I'm already pressing my thumb right through the screen.
It got that bad after Samsung published the update after people found out their ****ty fingerprint sensor can be fooled by having a screen protector on.
Since then, my fingerprint sensor has been pretty much all but useless.

Your not alone its crappy they should of kept it on the back

im very dissapointed with that fingerprint sensor on my predecessor p30 pro is it shame.. slow and inaccurate, maybe This is due to plastic foil but thats Thinnest foil What ever exists

It only works well if your fingers are little moisturized. Otherwise, it failed often

Yep, I have dry skin and that makes it extremely difficult for the scanner.

Man honestly I wish they would have put the scanner in the power button like on th Huawei mate30 pro

Yes it's rubbish. Worst fingerpront scanner on any phone I've owned. The poor scanner, dropped calls and scrolling issues stop this phone from being 10/10. All very big problems too. I would have kept my Note 8 and not bought this phone had I known.

I just don't use it, lol. Actually I don't use any lock screen at all, not even swipe. I find them annoying. I hide all my stuff in Termux which the average user or theif wouldn't think to look, or even know what they are looking at, lol. I could always lock it or erase it remotely with a few clicks on Google. As long as it's turned on and connected to the internet.

Try this

Register 2 fingerprints only for the same finger with many angles as you can,its worked well for me

I've stopped using the fingerprint scanner altogether and now use facial recognitiong (quick) which works flawlessly.

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 Do "approved" screen covers help with fingerprint scanner?

So I searched around and didn't find an exact answer so sorry if this has been asked/answered before. 6A with a Tocol glass screen cover. I was actually getting decent results prior to the Android 13 update but ever since the fingerprint reader is almost useless. I have deleted and relearned fingerprints multiple times both with and without increasing the screen sensitivity but nothing has worked. Has anyone tried the google approved screen covers and did they help?

It seems that most glass screen protectors work just okay for fingerprint in my experience. I have figured out that the trick seems to be setting it up right. The instructions indicate that you need to move you finger into various positions, but instead I have found that it is better to just use the finger position you typically will use but in varying degrees of pressure on the screen. I hope that makes sense....in other words it helps to put your finger on the screen lightly, then keep it in essentially the same position but press slightly harder several times.

Hmmm...that's an interesting idea. I'll have to give it a try, I've tried everything else. At some point I'll take the time to just remove my screen cover to see if it helps. Thanks!

I register my most used finger more than once and then some other fingers as well. For this phone, I registered my thumb twice (same thumb), index finger, and then another finger on my other hand.

forum.xda-developers.com

I've been using an old generic matte PET screen protector designed for an older pixel phone without any problems, so i don't think you need to get an "approved" one. I didn't increase sensitivity setting either.
6a's fingerprint reader works consistently for me, except maybe a rare misread every few months because my finger was very dry or something. In those instances, I unlock successfully with my other registered finger.
