[Q] How good is the fingerprint reader? - Samsung Galaxy S10+ Questions & Answers

Not how convenient is the placement - I can tell that in store, what I can't tell and most reviews doen't mention is mean how quickly and reliably does it recognise your fingerprint and how often does it miss, particularly are there any circumstances under which it consistently has trouble?
My current phone is a Galaxy S8, before that I had a Pixel. I plan on getting a new one in the next month or so, short listed to Galaxy S10+ or Pixel3 XL. One of my favourite things about the Pixel is the fingerprint reader, which worked pretty much first time, every time - when I picked it up the phone was unlocked by the time I was looking at the screen. The S8 not so much; I can work around the smaller, less well placed reader but it often has trouble reading my finger print. I've reregistered, rebooted, cleaned the reader etc many times, to no effect, it still has trouble particularly if my hands are cold (for a certain value of cold, never below freezing around here), skin is dry, skin is wet etc...
My partner has my old pixel, I still have a fingerprint registered on it and the pixel still consistently reads it first time, even when the S8 can't.
For me this is one of the make or break features on a phone, it's not covered in reviews and will be hard to test in store, so I'm asking this community - how good is the fingerprint reader on this phone?
(I'm posting this on both the Pixel 3XL and S10+ forums, apologies to those who follow both)

Honestly it works fine for me, but i dont use it much, I use the face unluck, any reason why you guys prefer fingerprint over face unluck ?

Yeah, they implemented the ultrasound sensor to make sure this type of authentication can't be attacked.
Face unlock is a flawed method and this phone doesn't even have the hardware to do a proper face authentication, it can be fooled by a picture.
Samsung should have disabled it but chose not to remove any stock Android features, so it is still present.
Regarding my experience with the fp sensor, it took some time to get used to the position but once that happened it's pretty much 10/10, definitely the fastest scanner I ever tried.
It is very sensitive to how you register it the first time, you need to register it in a natural position and it will work perfectly.

Fingerprint is very inconsistent for me. I've tried every method for success and it's just very hit and miss. I really use face unlock more just for my own convenience. I know it's really not secure but my phone never is never far away.

Face unlock is basically all I use. Miss the note 9 and my pixel 3 xl fingerprint sensor dearly!

You should ask how bad is the finger print unlocked instead how good. For me need two or three to unlock the screen

I really wish they would have left it on the back. It was flawless back there on my s8 plus. I love everything else on the phone but that. If it was more reliable this would be a non issue

When you get used to it, it's still only like 80% accurate. Randomly it will unlock super fast and other times it fails alot. It's really average.

I'd say about 90% but it is getting better. I haven't installed my white stone dome glass and currently using zaggs. I think more people are having trouble finding the sensor and placing their finger on top of it. Try turning the screen on to see where you need to hit and get use to it. After I've learned where it is, unlocking using fp has significantly improved at least through this screen protector

I was having issues until I added an additional finger but kept it the same one I have setup already. Now it works flawlessly.

When I initially got my phone (2 days before release) I registered my fingerprints ASAP. I did each finger twice and it worked alright, not the greatest but I assumed it was just a learning curve and muscle memory that I had to develop. I installed the newest update (ASBA) and it didn't seem to improve, initially. I removed my fingerprints and added them back, this time only once per finger and it honestly works better than before. I didn't do anything special when I deleted and added them again. I wonder if the fingerprints need to be added again after the ASBA update to actually benefit from the improved fingerprint recognition, as it appears that way for myself.

Fingerprints that are added on the s10 & s10+ get better over time with some ai trickery, google search s10 fingerprint ai, theres a sammobile read up...

In my S10+ is as bad as my A7 2017, I mostly use Face Unlock with "faster recognition " disabled, with that option off it won't be fooled with a picture anymore.

Had never issues with fingerprint reader. As I wrote somewhere else, best thing is to press softly when registering it and touch the sensor sometimes more right, left, up and down as you usually don´t hit the sensor exactly in the center in daily use. Anyway there was a little latency until screen woke up and maybe in one of ten cases it didn't work at the first time.
Now I did what you suggested. I deleted the former fingerprint and set a new one. And it´s not only some kind of feeling, it´s indeed much better now. Latency nearly has gone and the fingerprint recognition works absolutely perfect now. So thanks a lot for your advise. Obviously it is not the "AI" of the device but the "user intelligence" Samsung is learning from. The recent update did it - fixed it. Great now, thanks!!!!

I agree with you, is crap, I have to touch several times and if my skin is dry because of the climate compared to when I registered the fingerprints (much less climate), much worse.

I'd say that's the biggest issue. It has difficulty recognizing your finger when it is dry (and that is according to the climate). When I registered them initially it worked great because my hands were slightly more humid.
At times I have to rub my hands on my hair or something to get it to recognize the fingerprint. There has to be something that Samsung can do to fix this. Especially given that this is the only secure method to unlock your phone.

Maybe you're actually just a reptile, or alien race? Honestly, I have no problems at all with the scanner. I don't understand what the people who do have the problems are doing because IMO it has to be user error. I'm not saying it's flawless, but I never have to re-attempt a scan more than once. Which is pretty much on par with how often I'd need to retry with my S8+.
Now, I don't use a tempered glass protector, only the factory one that came with it so that might be an issue some people face. But honestly, everyone who wines about the fingerprint scanner are probably just too stupid to use it properly or something.

Fingerprint scanner. Do you use it?

Just wondering what people thought of the fingerprint scanner? I tried it today and I feel like it works ok. Sometimes it gets it first try and other times its hit or miss. Still though, privacy is important. Only thing I wish is that you didn't have to swipe your finger to get it to unlock. Considering the size of the phone I wish you could just place it down anywhere on the home button and have it work.
Thoughts?

At first I thought it was pointless, because it worked poorly for me. Now it reads every time. I'm not sure why the 2nd time took better. I know you can improve the chances by taking several (up to 6 I think) profiles of your finger. I use it with LastPass, which I love, that's good integration. I don't like it for locking the screen, I'm in my phone too much and it's just a slower operation. I agree, the sensor on the iPhone is way better, you don't even think about it. But I like having it for the password management.
I use it because foxfi requires a passcode more than just swipe. I use that. Works pretty good for me. Most times on first try
I absolutely use mine everyday. I think it's overlooked because of the bad rep that the s5 scanner had, this one is much improved. I agree that the iphone scanner is better but this one isn't bad at all granted you understand how to properly set it up. I wish you could lock individual apps with it but other than that I love it.

Maybe they'll do that with Lollipop and screen pinning?
Samsung? ?
Use mine.
The key is setting it up. When doing the 10 swipes use different angles and positions.
Once I set mine that route, 0 issues

Just wondering do you know how to reset it and start over. I want it to be able to read my left and right thumbs at different angles. The first time I did it I just used the same up down motion.

Settings>finger scanner>fingerprint manager, once in you can add or delete fingerprints, just delete them all and set up as you wish.
I used it, until I noticed that I had a bunch of really thin vertical scratches on the button. Haven't used it since. Now I'm using the pattern for my lock screen.
I must have really abrasive fingers or something.

i flashed a tmobile rom on DE, forgot to clear FP scanner. Now i am back to stock, i can't set it up or enable it.i get an error. so i'm doing the connect the dot unlock; i kinda like it cause its fast and i can use both hands.
I like the security of the finger print scanner. I tried removing it and using the the swipe to unlock feature, but found myself constantly using the finger print scanner out of habit so I just activated the feature again lol
I couldn't live without this feature now that I have it set up. This plus private mode have completely changed the way I manage my content and privacy. I love it.
i've honestly tried the fingerprint scanner so many times, and i always end up turning it off because it's frustrating and rarely reads my finger print.
Any tips?
Also what is Private mode ^
I saw it but haven't messed with it ,

Nope. Its one of like 47 useless (for me) features on my Note 4. It's simply, here's what I want: large screen that also looks awesome, removable battery, memory card slot, and lastly root. That's it, and I would possibly be even will to give up one, MAYBE two of those things. The Nexus 6 has one of the 4. The Note 4 has 3 of the 4, thus here I am, patiently waiting for root of the d.e. to get back in stock.

Have tried it on my note 4 and my previous S5. Maybe im just to lazy to take the time to get used to it, but in the short time ive used it the thing just infuriates me. sometimes requiring several swipes to unlock. I do like apples approach to the scanner better. Huawei has a phone with one like apples but on the back. i think its the perfect solution. the whole Swipe part of it is what sucks. The whole thing will be a moot point for me when lollipop hits the note 4 as I will simply make my Gear S a trusted device and not have a code at all as long as it is paired. I really only need security in case i lose my phone or it gets stolen. Until then I'll just stick to the pattern unlock.
I like to swipe my thumb sideways because it's easier to do with one hand. This worked well when the phone was naked, but my seidio case lifts my thumb as I slide it and makes an unreadable scan most times. I've stopped using it as a result.

Is the scanner only useful for logging in to the phone? The scanner on my HP laptop came with software to store passwords and enter them on Web sites and other places. That is how I'd like to use it.

Logging into the phone is the main use of it but you can also link it with PayPal to make purchases. Also I believe you can use it with last pass which is a password manager to log into different websites by scanning your finger.

Found an app on play store that let's you lock individual apps with your fingerprint. It's called finger security (by Rick clephas) it's quite robust and handy. Thought I'd share my find.

fingerprint reader issue

Hi folks,
Anyone else experiencing issues with the fingerprint reader?
I've set up the maximum if 5 fp, but interestingly all the 5 are the same finger.... And the device won't recognise my finger ad soon as I lock the phone.
Tried with different fingers= same result.....
No matter what I'm doing, clean cache, re-set, etc....
I've already exchanged the phone but the new one is the same....
Any idea how to fix it?
Sounds like your fingers aren't compatible. Is it a common practice to have the same finger registered five times? Only have once perfinger myself and never have an issue unlocking.
My experience is it gets a lot better with time. I did make two entries for my left thumb which helped increase read rate from maybe 2/3 to >9/10. Other fingers read well and got better. In sunlight, in dark, no problem it just works. If your fingerprints are in some way unusual or hard to read it may "just be you.".
Do you have a friend whose finger you can borrow to test things out? Rule out the phone ?

Tried with my wife's finger. It reads a little bit better,but the overall successfully unlock by fp is way below the acceptable number (tried around 10 times, unlocked around 3-5)

Oh that's awful! I'm consistently >9/10 after a month and half of use. Even early on was probably75%. Only problem I have is right after a shower it doesn't like swollen skin fingers.
As a test I just did 20 unlocks using the various four fingers i defined. Only one fail, and that was left thumb at an angle.
Phone is definitely better than iPhone 6 I have for work (50% rate).

How does everyone register their same finger more than once? It tells me I've already registered that finger?
I noticed a dramatic improvement when I washed my hands really well, cleaned my screen, THEN registered my fingers.
Are you using a screen protector? If you are that is probably your problem.

LOUSY fingerprint sensor, contemplating return

Got my 6T 8 days ago, love everything about the phone but the fingerprint sensor. Words cannot describe how aggravating it is. On a good day it takes at least a full second to respond. It does not work if I recently took a shower, if my hands are cold, if there is a minor amount of debris on my fingerprint, after washing my hands. The sensor fails to recognize my left thumb 50% of the time no matter how many times I redefine the fingerprint. I have gone as far as having separate imprints taken in bright and dark conditions, to no effect. When the sensor does work on my left thumb it takes twondull seconds.
I am THIS close to returning the phone while I can still do so. Have there been any rumors whether the 7 will use an ultraonic sensor? I love OP phknes but they blew it with the 6T sensor big time.
I have had zero problems with mine, even after applying a tempered glass cover it works great. I thought that I would have to redo my prints after installing the glass cover, but it worked just as fast as it did with the original cover. Maybe the sensor on yours is faulty and an exchange will fix the problem?

Running the latest beta and my FP sencor unlocks instantly..
Also change the animation to McLaren
Been using the 6T since the release, at first the fp was kinda slow, few misreads, but now (since a month or two) it works great, it can even unlock with half of the finger on the sensor. It even works if there is a thin layer of some substance on the finger. It was never unreliable for me. Now it works perfectly.
I had issues initially and didn't really like it, finding a lot of rescans to get the phone to unlock. After a lot of trial and error, for me, I found the best technique is to lightly put your finger on the scanner. It seems to unlock fine, first time now for me. I think the McLaren animation is just a perception that the phone is unlocking quicker. I actually have the animation disabled and don't notice any difference in speed compared to with it on.
It seems that the efficiency of the fingerprint sensor is highly dependent on ambient lighting. Things work somewhat well at night and indoor. Outside in bright daylight they generally suck. This kind of makes sense, one way to reduce this is to make sure that your finger fully covers the sensor area, with as much overlap as you can get away with.
FP sensor doing my head in on my McLaren 6T. Lately I have seen it becoming less and less accurate. It takes a few tries to unlock and sometimes I have to enter the pin since it will not allow any more tries. Tried deleting and adding the FP's but to no avail. Disabled the option for the time being. Probably the worst aspect of this phone if you ask me. Have the original glass screen protector on.
Mine wasn't great on the original T-Mobile firmware, but since I've converted to international 9.0.12 it's been flawless. Sounds like you may have a faulty device, unless you haven't updated?
I registered my dominant finger twice. It did the trick for me.
Bright lockscreen background and register finger twice has improved it a lot,bit it will never be as good as the standard Scanners
Mine seems to not work as well with my left thumb compared to my right. It isn't as good as my old pixel 2 xl fp sensor, but not horrible either. Just the left is wonky no matter how many times I re-register. Maybe light or my fingerprint.
This is def cutting edge technology through the screen for a fingerprint compared to others. But it ultimately works real reliably with my right thumb.

Try and redo all your prints in a dark room. Helped me out tremendously
My 6T fingerprint detection is as good as on my 3T, and far better than on my iPhone 6. I did have to register my left thumb twice to get good detection. I have no problem in the dark, interior light, or bright sunlight. In all cases with any of my four registered fingers I get 9 or 10 good scans out of 10.
The only circumstance where it routinely had trouble is "fresh out of the shower" fingers. The slight swelling or whatever due to warm water throws it off for sure. After 5-10 minutes it is back to working reliably though.
I have had mine about a month now and struggled with the fp sensor as well. I've changed the animation, re-registered the same finger/thumb twice, nothing seemed to work very well.
Here is what worked for me, when registering the fp, press very lightly. I'm used to using a standard sensor and always press very firmly.
My thought is that since it's through the glass, pressing too hard distorts the fp and results in problems.
My recommendation is to stop retraining it. It learns the more you use it (Oneplus confimed). Stick with it for a week and you'll see a massive difference. Mine is just as flawless as my OP3 now, No issues at all.

Ultrasonic aren't better, check the Galaxy one (even worst in some case), they are on the other hand more secure.
I cant get myself in using it, the face unlock beats me to placing my finger every single time anyways lol.

How did you do his? Every time I try it I am told that the finger is already registered.
On a more positive note after following some of the suggestions here things are definitely looking up. The stuff that made the biggest difference
1. Press lightly when defining FP
2. Register FP is a somewhat dim environment
3. Make sure they center point of fingerprint is scanned during the fist phase, so that the finger covers the green spot solidly.
4. Get a good sampling of the center and edge during the two stages
5. The McLaren animation makes a notable difference

I kept changing my finger position little by little when it showed already registered, to give the phone maximum coverage of the finger. Changing the pressure also makes difference.
Also the McLaren effect helps a lot in this case, I believe.

Fingerprint Problems - Can it even be fixed with a future software update?

Yesterday my fingerprint was working about 90% of the time, today it's complete trash.
Also there is a setting in the phone where it will completely wipe and factory reset your device after 15 failed attempts. With this crappy scanner it's a good thing to uncheck this option before your phone gets wiped.
Can this problem even be fixed with a future software update or is it flawed hardware?
Not too happy about a $1,600. phone with a crappy fingerprint scanner.
Don't worry about the factory wiping aft 15 attempts. The phone will ask you for an alternate method (pin or pattern) to unlock the phone once the 5th fingerprint attempt fails.
I think Samsung will improve it with future updates, but not by much.
I would not hold out much hope for an improvement. If you want to see improvement you need to do three things:
1. You need to enroll your primary finger at least 2, ideally 3 times.
2. When you are enrolling your finger, don't follow the instructions to move your finger around, rather just naturally grip your device as you would when you grab your phone to unlock it, and only scan that way.
3. This is the most contentious one, but probably the biggest difference. Do not use any screen protector at all. Any physical barrier is a sound barrier, and therefore an ultrasonic sensor will perform worse the more layers of stuff there is on top of it.

I tried this once I got the phone enrolled my finger twice... problem solved..
One thing that the fingerprint sensor does not do well with, for some bizarre reason, is dry skin. If you have really dry fingers or the weather is very dry causing you to have dry fingertips, the sensor is definitely more prone to failure when scanning.
I also found one bug just a few minutes ago. If you have a Bixby routine running with widgets, you are required to unlock your phone to see the widgets, but the fingerprint sensor us disabled in this mode and needs you to explicitly press the unlock option before it will even scan.
A completely dry finger is the main problem. Try licking your finger and then try to unlock the phone. It would unlock the phone extremely fast and easy.
I don't know how this can be improved with a software update...
Fyi I am using the preinstalled screen protector. I agree that it would work much better without it. But I am afraid to leave the screen unprotected... What do you think?

A completely dry finger is the main problem. Try licking your finger and then try to unlock the phone. It would unlock the phone extremely fast and easy.
I don't know how this can be improved with a software update...

lol,... and since the flu season isn't over yet, remember to wash your hands thoroughly before licking your fingers to avoid catching any bugs. Sorry, I know it's not that funny to deal with the fp sensor, it's just ridiculous. I personally went through that before sending it back and getting S10e. "my life is much better now..." :laugh:
Follow this, I get it 99% of the time.
$1,600. phone and I have to lick my finger to unlock the damn thing.
Guys it may seem stupid but I was reading a post about the S10+ fingerprint sensor and think I have the way it was supposed to be used figured out. They described using it as jabbing the screen
WHy wouldnt you use face unlock?

Because it's not supposed to be used on this device, it's unsafe and the S10 doesn't have an Iris scanner anymore, it will get fooled by a simple picture.

Don't worry. Once the S11 comes out the FPS issues will be history and you will also get Android 10 plus the latest security patch, or at the very least one that's no more than 3 months old. That will be $2000 please.

Rushed out? What are you even talking about?
They clearly specified that Android's face unlock is crap and it should be deleted, except Samsung never deletes stock android features, just don't touch it and use the bloody world's most advanced fingerprint authentication.
Try keeping hands moisturized with lotion instead of spitting :crying:. i use a lot of alcohol at work which dries my fingers out. after using lotion finger print worked a lot better. Keep Moisturized boys and girls lol

Definitely a two step security thing. Now your wife / husband has to lick your finger first for unlocking your device while you're sleeping
Guys, very good tip that actually works great. Watch the video.

Very slow Fingerprint sensor out of the box faulty

To say up front I have had 4 previous S10s (3 S10s and 1 S10+) so have some comparison and today picked up the ceramic white S10+ .
Immediately out of the box the FPS feels really really slow, it was never quick on the other devices but this feels like it is in slow motion. Setting up in the first instance was painful with lots of prompts to 'press harder' I have not removed the screen protector yet but I did not on the other eithers and it is noticeable slower than they were. It may be my imagination but the screen protector looks thicker than the others did but that could be my imagination or memory deceiving me, I may try removing it in a bit.
Just wondering if anybody else has experienced this on an S10 or S10+?

Yes, and after S10+, S10 I've happily settled with S10e. A perfect 10! (Samsung S10 that is)

There was an update that came out that helped with this, is your phone up-to-date with the OTA's?
Just update your device to the latest version and it's very very fast ?
Removing the protector made all the difference. Must have been a dodgy one or as suspected just thicker.

I had a Whitestone Dome glass on mine for the past few months and it was so hit or miss I pretty much completely switched over to face unlock, I think this was mainly due to my dry skin. Yesterday I decided to rip the Dome glass off because I got tired of the fingerprint never working properly and boy is it night and day without it even with dry skin. Without the Dome glass it is super quick and I haven't had any issues or hiccups in the last 24 hours and I've deactivated face unlock.
My FPS works fine but my problem is that when I first turn on my phone it always forces me to use the pattern unlock method to unlock my phone without any option to use the fingerprints scanner. I do have the FPS set as my preferred security method and it works for apps and when the screen turns off but when I power down and turn back on I always have to use the pattern. Is there any way to fix this?

Yeh and also if you've not used the phone for a while itll ask for pin/password etc for security reasons.

Yeah and also, I find deleting and re registering fingerprints after 2 months good. Seems like my fingerprints on my skin shift slightly.

Thanks, I thought it was a setting thing. It seems odd to me that Samsung wants users to use less secure methods than fingerprint scanner to first unlock the phone. Isn't the scanner the most difficult method to hack?
