[Galaxy Note 4 General] AndroidNoob22:
At first when I got the device I thought the scanner was garbage (I was garbage not the scanner :3) used to get 30-40% accuracy, I was swiping my finger on the scanner in same direction (downwards) everytime as instructed while registering, when it dint work well I turned it off, then I came across few threads n vids and understood I have to swipe my whole pad in from different variations and angles while registering I tried that and woila, I have almost 99% accuracy now, it works sooo soo good now, been using it since more than a week and I unlock it around minimum 50 times a day using it and also use some apps I've assigned fingerprint to and I've only failed once since I corrected the method of registering finger. so yup, awesome scanner much btr than s5 the only trick is to register from diff angles as shown in video n you'll be good to go.. :good:
[Galaxy Note 4 General] Slai:
I dont care how well it works with two hands, its the thumb on my right hand when using the device onehanded thats the "problem".

It works most of the time, and ive registered my right thumb in various angles and variations like in the video. But not all the time. Its fine for normal use, though, it really is. But if you have a shorter thumb than me, it might be a lot worse. Even for me, its a bit of a dud due to the fact that it sometimes doesnt register (my thumb might be slightly off center, or I swipe too fast, etc).

The more reasonable method would be a slimmer bezel at the bottom, drop the scanner on the homebutton, add a onepress scanner at the back of the device for your index, instead of that horribly useless heartrate/oxygenlevel monitor.
[Galaxy Note 4 General] inaya45:
i tried the fingerprint scanner, did it 10 times to recognize it and set it but it didn't show up so i restarted my new note 4 and it worked and i swiped my finger and it unlocked then i locked it again but the fingerprint scanner went away again and its only giving me an option to swipe to unlock.
[Galaxy Note 4 General] Archiimonde:
I tried to set up the fingerprint scanner several times with different methods/angles. I was unable to get a good experience unlocking it with one hand. The iPhone is miles better in this department. Works almost every time two-handed, though.
[Galaxy Note 4 General] Andrewtst:
The way Samsung design it sense is not good. You need gently swipe down which simply look stupid and troublesome.

This part no deny iPhone did it great by press and hold only.
[Galaxy Note 4 General] Slai:
Agreed. That being said, I dont see any real point of it. Its much like the UV sensor, the heartrate sensor and all that other jazz.
[Galaxy Note 4 General] ozaghloul:
The fingerprint scanner is just pure garbage. Not sure why so many are blaming Samsung for not giving proper instructions? Everything in that video the OP posted is clearly explained in the fingerprint registration stage. It even has an animated finger that shows you how to scan different parts of the finger and different angles and directions. Its not that we have not registered the fingerprint properly, its that the scanner is just worse than ebola and aids combined. The poll results also support my assertion that the scanner is totally sh1t.

The fingerprint scanner is not jazz. If it worked properly most people could get some real use of the fingerprint scanner versus the UV sensor.
[Galaxy Note 4 General] Slai:
The only real use would be protecting certain apps and unlocking the phone. Both of which are easily doable with a PIN. that being said I don't have a problem using the scanner with one hand nor two, but it's not 100%, I agree it should have been better placed. Preferably at the back under the camera for your index.

I guess I get about 9/10 first try unlocks at this point, one handed.
[Galaxy Note 4 General] Magnesus:
I have tried all the methods and it still is mostly garbage for me. And it starts registering the swipe after a half-second delay which means you need to wait for the screen to turn on and for the arrow to show up - what a waste of time. It is also only 10% accurate for me (even when I have registered 15 different angles for the one finger I use). Maybe a software update will make it a bit better, who knows. For now - I will turn it off as before.
[Galaxy Note 4 General] Slai:
Maybe just register in the same-ish angles...
[Galaxy Note 4 General] Tom-Helge:
I still don't see what the problem is. I still have 99% success with my fingerprint scanner. It simply just works every time i'm using it.

Either you are setting the fingerprint scanner up in a wrong way, using it wrong, or there must be some problems with the fingerprint scanner.

I'm even tempted to make a video that shows how good my fingerprint scanner works just to prove it :).

And lastly. Even if Touch ID on the iPhone is more easy to use, it's far from being more secure than the fingerprint scanner on the Galaxy S5 / Note 4. Because on Touch ID, you just presses directly on top of the home button on the iPhone, which leaves your fingerprint open to anyone who manage to steal your iPhone. On the Galaxy S5 / Note 4, you have to swipe to get it to work, which means that you are actually swiping away the fingerprint on the button as you swipe.

Because of that, a thief is going to have a hard time to find your actual fingerprint to use to open the phone.
[Galaxy Note 4 General] Archiimonde:
If you can make a video where you at least 10 times in a row unlock the phone, while holding it comfortably in one hand, I'll believe you. I'm talking about unlocking it with the same hand holding the phone, not two hands. If so many people have problems with the scanner, Samsung either has piss poor quality control, or it's just inferior by design.

And have you ever used an iPhone at all? There's no usable track of your fingerprint after you unlocked the phone. Unless you have very greasy fingers, in which case you wouldn't be able to unlock the phone anyway.

Samsung did most things right with the Note 4, but the fingerprint sensor wasn't one of them.
[Galaxy Note 4 General] an_xda:
This is ridiculous. We can blame Samsung for building a swipe-scanner rather than touch like Apple but what is this unlocking with one hand business? Look at how big the device is, I would think you have higher risk of dropping the device than it failing for you when you swipe with one hand given the device is top heavy based on how one would hold it if attempting to one-hand finger unlock.

However, if your device lays flat on a table when trying to unlock, make sure you get it at the same angle you registered it at...
[Galaxy Note 4 General] shollywood:
Couldn't agree more.. Look at the poll... Clearly doesn't work like it should.
[Galaxy Note 4 General] Archiimonde:
For me, having a fingerprint sensor is mostly for convenience. If I'm already holding my phone and have both hands available, it's not much faster than using a pattern or PIN code. Especially when I'm in a hurry or wanna check something quickly, pattern or PIN is much more reliable, because I'm "swiping too fast".
[Galaxy Note 4 General] an_xda:
That is your use case. For my corporate IT policy, we require an 8-character (not just 8 digit PIN). This is effectively typing a complex password every time I need to unlock my device. The fingerprint scanner alleviates this pain and it has worked almost flawlessly on the S5 for me, let alone the Note 4...

If using the PIN or pattern works for you, you can ignore the fingerprint scanner then. Just another useless Samsung gimmick, right?
[Galaxy Note 4 General] Slai:
Oh, even I could do that. That doesnt prove much though, just confirms that it works 10 times in a row. Doesnt take in to account a bumpy busride, or when youre in a hurry, or if it rained ever, or if youre nervous, etc.
[Galaxy Note 4 General] Wally93:
I saw a video a while ago explaining why people with an S5 had so much trouble using the fingerprint sensor: part of it was under the screen and you had to swipe over a part of the screen too. Just like in the video you posted.

I for instance am able to unlock my note 4 by only touching the home button with my index finger. This proves the fingerprint sensor is completely in the home button. And also why there are no dots on the lower part of the screen indicating you should swipe on them like that tab S and S5
[Galaxy Note 4 General] Zamboney:
I still think it sucks awfully after registering 20 fingerprints of the same finger. Never again a swipe-style scanner for me.
[Galaxy Note 4 General] akirax:
Can you give me more information and link to the news?

Cheers.

[Galaxy Note 4 General] zipolly:
I've had my note 4 for about 4 months now and registered my fingerprint or thumbprint in my case when I received it , I can honestly say it's been excellent and very rarely misses , I hold and unlock my phone in one hand (my left hand) and it works flawlessly so I can only assume I've been very lucky ...... absolutely love it.
[Galaxy Note 4 General] MSK1:
Do u swipe up with ur thumb?

That's what I do... 99% success rate.
[Galaxy Note 4 General] zipolly:
Yes I swipe my thumb and it works like a charm in the last few days I honestly can't think of one instance where it's failed me.
[Galaxy Note 4 General] strifej:
I get close to 100% when using index finger, but 50-70% using thumb. I think the scanner is just designed for non-thumb use. I've tried swipe up as well as the standard down. Even when setting 2 fingerpints to the same thumb still results in poor matches.
[Galaxy Note 4 General] RayTrue04:
Mine is perfect. Works with all six fingers I have registered on first try 99% of the time.
[Galaxy Note 4 General] macmobile:
How stupid from Samsung to change a perfect feature! [emoji6]
[Galaxy Note 4 General] Archiimonde:
Fair enough
[Galaxy Note 4 General] Tom-Helge:
Alright. Yeah, as Slai is saying, the fingerprint scanner will be a bit cumbersome to use when you are in a hurry. I agree with that.

I'm also gonna be honest and say that a fingerprint scanner would be best to have on the backside of the phone as it will make the use of it much easier.

However, the fingerprint scanner is still working pretty damn good when you can swipe it while holding it with one hand or if you have the phone on the table.

I even figured out one more thing. You can even swipe upwards to and not just down on the fingerprint scanner. If you have registered a finger on the fingerprint scanner, then try to use the finger upwards on the same finger. It works for me.

So maybe some of the use will be a little easier for some with that.
[Galaxy Note 4 General] Wooba99:
If I try swiping upwards the phone says down only. If I go down I'm either going too fast, too slow, am not centered or not covering the entire button. This scanner absolutely sucks. A big disappointment, it was something I really was looking forward to.
[Galaxy Note 4 General] Slai:
I use it. It mostly lets me in on the first try when using it onehanded. I merely did the swipes normally with one hand, same thumb for two of the three possible registrations. No funny angles or anything, just different "sides" of the thumb on a few of them, like if the "sides" of a barrel would be called "sides". Did one for my left hand thumb as well as sometimes I twohand it on unlock, especially if Im sitting down or so. And it works fine unless I REALLY rush it. It gets easier with use, apparently. At first I disowned it completely, but gave it another try for a few days.

But I still dont see it as any big deal, its just a mildly faster pincode/pattern unlock.
[Galaxy Note 4 General] Tom-Helge:
Here is the proof (filmed by me) that the fingerprint scanner works as good to swipe upwards as it works to swipe downwards.

It's filmed with my old Samsung Galaxy S4 which have a strange sound recording issue. After 5 seconds, it switches to mono sound. But the sound doesn't matter in this case anyways.

[YOUTUBE]NF1AeTp5PFg[/YOUTUBE]
[Galaxy Note 4 General] Slai:
Thats pretty sweet! Ill give that a try myself. Thanks!
[Galaxy Note 4 General] Tom-Helge:
Yeah. It's pretty simple. If you register your thumb where you are swiping it down from the side when you are holding it, your just register that. After that, you can use that registered fingerprint to swipe up and down.

So if you are registering 3 fingers, it means that all those 3 fingers can be used to swipe up and down. So it's pretty neat.

Not sure if Galaxy S5 had that ability though?
[Galaxy Note 4 General] Slai:
I have no idea. I skipped over the SGS5 myself. What a load of garbage... Note 3 all the way. Can anyone confirm that it worked/didnt work on the S5?
[Galaxy Note 4 General] chamberc:
The note 4 is only slightly better all around than the S5. I've had the S3, S4, S5, and now the Note 4. They're each only slightly better all around than the predecessor.
[Galaxy Note 4 General] Slai:
I disagree completely. There certainly is nothing "slight" about the design, the SPen, multitasking features nor screen for me in comparison to the S5.

I've had the S2, S3, S4, Note3 and Note4 myself. None of the phones before the Note 3 even came close to the level of awesome it and its younger brother provides me. The only one that ever came close was the Nokia N900, and that includes N97, N8, N9, Lumia800 and Lumia920.
[Galaxy Note 4 General] chamberc:
Well, everyone has an opinion.
[Galaxy Note 4 General] Slai:
Yeah. If I thought the s5 was worth it, I'd get it. But it really can't touch the note 3 nor note 4 for my use and preferences.

I get that some like it, though.
[Galaxy Note 4 General] Magnesus:
I have tried to register the fingerprints reeeeally slowly. They work for now. Let's see if it lasts - last time I have change them they stopped working after a while (well they dropped from 100% ratio to about 10%).

EDIT: Nope, an hour later it stopped working almost completely - now the accuracy is between 10% and 33% for me. I will wait for an update, maybe it will be fixed one day, because it would be a nice feature if it worked well.
[Galaxy Note 4 General] Tom-Helge:
I believe it's either a software issue or that the fingerprint scanner is broken, or somewhat broken as i don't have this issue at all.

My fingerprint scanner works as good today as it did when i got it (21.10.2014).
[Galaxy Note 4 General] cyprian64:
Thank you for this Tom!
[Galaxy Note 4 General] Wooba99:
It absolutely will not work for me. Here's what I get (the lock screen gives the same results)
[Galaxy Note 4 General] Tom-Helge:
Weird.

Are you sure that the button are clean and stuffs?
[Galaxy Note 4 General] Wooba99:
Clean, dirty, whatever, it doesn't matter. The scanner was one of the first things I tried taking it out of the box. I give it less than a 5% success rate.
[Galaxy Note 4 General] Tom-Helge:
To me it sounds like you have a somewhat defect on your fingerprint scanner. I would get a new one on the warranty if i was you.
[Galaxy Note 4 General] Wooba99:
To be fair, I just tried it a couple of minutes ago using 2 handed method, with the thumb going vertically rather than sort of diagonal and it seemed to be a high rate of success. But since I unlock my phone one handed 99.9% of the time it really isn't useful like that.
[Galaxy Note 4 General] mikey123:
I can register any finger swiping downward with ease but when I try to swipe sideways is when I have the problem. The weird thing is I can get my 10 sideways swipes registered with my thumb but then when I actually try to unlock my screen I never can do it and I always have to use my passcode
[Galaxy Note 4 General] pdiddy3g:
Finger print scanner

I am not a big fan of fingerprint scanner. There is no pint is using this thing. I know many Apple users are using it just the sake of using it. I asked my friend who is an Apple fanboy. He thinks it's cool. I asked him why you need one. He had no answer.

There are tons of other way to lock yor phone and it is just a phone.
[Galaxy Note 4 General] Archiimonde:
For me, it's not that I needed one, but it was insanely convenient. If I was to unlock the phone, I would just press the home button with my thumb, and it would unlock the same moment the screen turned on. It was almost like it wasn't there.

As for the note 4, it seems like it's working better now. Still far behind the iPhone's, but much much better than I initially thought.
[Galaxy Note 4 General] CapitanFantasma:
in my case I will have this problem, there is solution?
[Galaxy Note 4 General] mdiaz33685:
that happened to me, it got effed up... after rooting, I see people saying to delete or removed the saved scanned fingerprint files....

I had to return my phone and get another one.. 2 days after rooting, I have not rooted this one yet,,,

a lot got it to work after using odin flash firmware made for your phone... try that, it should work,

others like me... I didn't work... it got screwed up somehow... don't know why...

would like to know if it works, pm me please.... odin flash the firmware.. let me know... recommend to go into recovery wipe everything except sdcard and ext sdcard and reboot into downloader mode. then odin flash firmware...
[Galaxy Note 4 General] CapitanFantasma:
sorry for my language not very good English

and try what you say and still not working. I have only one question that may be my salvation, when I had my note without changing it I realized that I had the original rom came without the application of whatsapp and lower my stock rom after sammobil came with whatsapp .. I must have originally same rom that came with the factory my note but not how to get that firmware. is not the same stock that originally had

I need to find the original firmware that came to my note, not the one in sammobil

I have a note 4 sprint
[Galaxy Note 4 General] dr.m0x:
Placement of the scanner sucks. It's hard to swipe it with one hand and sometimes the lip on my case seems to get in the way
[Galaxy Note 4 General] Slai:
So your case is horrible.

I find it fine to swipe with one hand. But yes, it's inferior to the Huawei solution.
[Galaxy Note 4 General] mdiaz33685:
this is where I get my firmwares to make my roms...

1 - http://www.sammobile.com/firmwares/

or

2- https://samsung-updates.com/

my phone is called SM-N910T - Tmobile USA - look for your model phone and download the correct firmware..

Instructions

•Extract (unzip) the firmware file

•Download Odin v3.09

•Extract Odin zip-file

•Open Odin v3.09

•Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons)

•Connect phone and wait until you get a blue sign in Odin

•Add the firmware file to AP / PDA

•Make sure re-partition is NOT ticked

•Click the start button, sit back and wait a few minutes
[Galaxy Note 4 General] CapitanFantasma:
does not work with stock rom sammobil my fingerprint detector. but I repeat clearly remember when I bought my note 4 originally came without apps like whatsapp. in stock rom sammobil come more applications installed originally were not coming when I bought my note 4 sprint and works there if detector traces. want to find the stock rom that originally had my sprint when you buy note.

maybe installing the stock ROM that was originally able to work again my fingerprint detector. but can not find rom stock I had at first I'm sure was different and not the sammobil
[Galaxy Note 4 General] electech13:
I've heard about some defect issues and yes goes without saying that the placement of the scanner isn't the best but if setup properly it seems to work well.

I haven't done the thumb setup.. Always index finger and I'm still hitting 98% success and I use it all the time..

A gimmick sure... Not for everyone but I like it.

I'm coming from Roms where I used 10 digit pin to unlock and the keypad always reorganized the number layout. I always wished that feature came in stock..

The worst part about this fingerprint sensor is that it is not Exchange/ActiveSync compatible, this is on Samsung's fault, not my corporation... :(
[Galaxy Note 4 General] Slai:
TomHelge: I thought it was something I wouldnt really want nor use. Turns out; I kind of like it! I wish they had gone the route of Huawei Mate 7, that method seems far better.

I like it for unlocking (cause why not), and more so for just locking down certain apps. I dont want people rummaging around my file explorer, nor my gallery, or notes, etc. So I just secure them with a fingerprint swipe. Besides the awesome method of activating windowed mode, and the spen itself, this is actually something Im missing now when Im back on my Note 3.

Weird how things like these turn out. Its like wireless charging and the SPen; you think "hah, gimmick" then you use it and go "Y U NO SUNAR IN MY LAIF?!? WERE U BIN??? I HEART U!!!"
[Galaxy Note 4 General] skyred5:
the guide helped me out quite a lot. Have been always getting the error messages. Now it's about close to always getting unlocked on first try as compared to my initial setup. I did what generally many people would do; swipe 10 times same way, but I registered my 2nd scan as my thumb on side ways, 10 times.

It's not always the hardware issue or the accuracy, but how we as humans give the information to our devices. If the devices are unable to understand the command/info we give, then we have to change the way we provide the information/command to the device(since tech devices are not always flexible). This video demonstrate this point clearly and it applies not just to note 4 fingerprint scanner, but also to any tech device.
[Galaxy Note 4 General] schlepprock:
My fingerprint scanner has officially crashed. I had to deactivate it due to it stopped working all together and when I go to choose it again it keeps giving an error that the fingerprint scanner has stopped if it keeps giving this error to restart the device. The thing is restarting it doesn't fix it. I also get a Touchwiz home has stopped working when I restart my phone. I'm gonna try a factory reset this weekend... Thoughts

Galaxy Note4
[Galaxy Note 4 General] couragedragon:
I haven't watched the video, but mine works great. I was skeptical, but I only have my two thumbs scanned (and sideways nonetheless!). I swipe my thumb sideways down when I'm holding it one handed. And it works most of the time just fine. I'll have to add my fingers and or thumbs for when my phone is flat on the table.

Other than that, works great for me.
[Galaxy Note 4 General] crazydeepman:
Only at the first was bad now is good and easy to do it just a habituation
[Galaxy Note 4 General] riz157:
Finger print is frustrating at best.

Will only work using 2 hands not convenient at all and work 30% of the time. :(

Crappy feature.
[Galaxy Note 4 General] andrawer:
Huh? single handed with either thumb is the only way I unlock my N4.
[Galaxy Note 4 General] Slai:
Works fine for me with one hand.
[Galaxy Note 4 General] Tom-Helge:
Just because you aren't smart enough to understand how to get the fingerprint scanner to work good, it's not bad because of that.

The only downside with the fingerprint scanner is the placement. However, if you use some time to get used to the placement and use the fingerprint scanner as it is, it will work really good.

And also, the poll says that 63% of all who have answered on the poll says the fingerprint scanner works really good after following the setup video in my first post and after using the fingerprint scanner a little after that.
[Galaxy Note 4 General] EVOme:
OP, your video contradicts every other way to make it better that I've seen. You state scan finger in many directions. Others state that's the problem. Just scan in one direction. As the guy above said, the scanner just sucks. 30% seems about right. It isn't meant for one hand use to unlock. I never unlock using two hands, so it's useless to me. I went back to pattern about 3 weeks ago.
