Fingerprint sensor - anyone else finding it extremely bad? - Samsung Galaxy Z Fold 2 Questions & Answers

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!

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.

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.

Fingerprint Scranner Location A Problem? No!

All the YouTube dread over the location of the fingerprint scanner will not be a problem for most. This is a Urban Armor Gear Case (UaG) for the Galaxy S8+. It will not be a problem for me.
Everyone has different sized and shaped hands, that's where the problem lies, it not being a problem for you doesn't mean that it will work for everyone. Left handed people will also have to hold their hands in an awkward position to hit the scanner, I personally won't have any problem with it, but I know that people with smaller hands will

You do realise you are going to be putting greasy fingerprints right over the camera lense every time you try to unlock it right? It is slightly less of a problem for people holding it/unlocking it with their left hand (i hold with left and tap with right so its not quite so bad for me) but its still stupid placement. Putting it BELOW the camera instead of next to it would have made it easier to reach for smaller hands, easier to reach for people unlocking with the right hand, and greatly reduce the chances of hitting the camera lense instead.
It's just plain dumb design and that was obvious right from the first leaks showing where it was, so how the geniuses at samsung couldn't see that right from the start I have no idea. It was probably a rush decision after they failed to integrate it into the screen but its so clearly a stupid location for it that even a rush decision shouldn't have resulted in locating it there.
I may be slightly harsh, but this isn't a mid range phone, its the very top end of the top end and for the money they decided to charge for it, it should be damn near perfect.
I'm a lefty so I'm just going to run my finger along the back until I feel the sensor. Doubt I'll have many problems with wiping my camera lense. And I also rarely take pictures so I have that going for me as well.
Looks like you will be covering up at least 50% of the camera at the same time.
I dont even think about to use fingerprint sensor on s8+
Nope!
I'm just the opposite. If I try to do it with my left index finger, the scanner is too close. It's awkward for me to try using my left index finger. With the UAG case, I'll easily be able to keep away from the camera lense.

The LG V20 has the fingerprint scanner on the back. I don't know until I see the actual device, but I think the S8 once you get used to it, it should be fine.
I don't think it will be much of an issue either. But the S8 is just so fantastic you need to find a con somewhere
Honestly, I won't even use it. I hold my phone really low compared to most, I guess.
Can someone confirm how fast/reliable the iris scanner is? Also, does having it on make a noticeable impact on battery life?
im using an iphone 7 plus and i wipe my camera every time i use it and theres no fingerprint scanner back there hahahaha people are weird

I hear you and agree with the caveat that people with small hands need to purchase a mobile that they can handle efficiently. The S8 and S8+ are not designed for people with small hands? Its very much a question of compromise. If one desires a screen as large as the S8's then one will need larger than average hands or accept small handed users will need two handed operation. :good:
I don't mind the scanner being where it is. I owned a zenphone with the scanner on the back right underneath the camera. I had zero problems after acclimatising myself to such a layout.

I can comment on the fingerprint scanner, it is very fast - near instantaneous, the only issue is that it takes longer to hit the right spot that it does for it to open the phone. as everyone already mentioned it is in a bad/awkward spot. i tend to either hit the camera or the flash when trying to use it. eventually ill train myself to hit the right area, but its not intuitive.
Just checked the s8/s8+ out at Best Buy. The s8+ was perfect for me just doing a quick hands on with the finger print scanner. I thought it would be weird but it was easy for me to use but my hands are bigger than average.
Not looking forward to getting used to this. I have smaller than average hands and I know it will be awkward, but I'll try to survive.
I also am aggravated by the fact that it is impossible for one handed operation on a desk or table. I am work and it just takes a finger swipe with my phone on the desk, but now it will take entering a pin since the FP scanner is on the back and the my face isn't over the screen.

That is the other irritating thing about it being on the back, when I have the phone in a dock or on the desk I am going to end up picking it up to unlock it instead of just putting my finger on a front facing scanner. I know you can have the iris scanner AND the fingerprint scanner active, but with the iris scanner i would still have to pick the phone up to point it at my eyes so its pretty useless, it will need a pin like you said.
On the back is a way better place for the fingerprint scanner than on the front. On my Nexus 6P I can unlock the phone whilst picking it up single handedly. If the finger print scanner were on the front I'd have to pick it up with one hand and use the other hand to unlock it. The size of the phone, the Nexus 6P and the S8 (The plus in particular) mean that bringing your thumb to where a home button would be would be difficult/painful.

Ummm, so how do you use the phone with 1 hand if you cant reach the home or back buttons??
And you could just pick it up so your thumb CAN reach the front, seeing as you will have to use the home buttons and back buttons anyway....

When I unlock the phone it's usually got my internet browser open which is likely what I'm going to be using, so I'm not looking to use the Home/Back buttons.

Coming from a OP5 and concern with front fingerprint sensor not there

How did you guys manage when the phone is on your desk or a flat surface to unlock quickly like it was possible with the front fingerprint sensor on the OP5?
U will get used to it
I started to use face unlocking too, I have both set up and using the one that comes handy at that time.
I tried face unlocking on S8 and it sucked, it was very slow and I barely used it. On OnePlus 6 it is almost instant, you'll love it
btw: rear mounted fp reader is much safer for one handed use when unlocking while walking
I had this reservation as well, however i got the phone anyways.
Honestly, i love the face unlock, its amazingly fast.
A tip if you want fingerprints added as well:
I noticed also adding the side of my finger as a secondary "fingerprint" improved my success rate when using it, i often find the side of my finger hitting the sensor due to my way of holding the phone.
Coming from a Nexus 6p, I'm completely used to a rear fingerprint sensor, so no issues with OP6. My wife has used Samsung phones for quite a while now and I occasionally use her devices. I found the front sensor a bit clumsy, but that's surely just because I wasn't used to holding a phone that way. I wouldn't be too concerned about the difference between front and back. We humans usually have a way of adapting!

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

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.

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.
