Hello.
I see peoples around on the internet (here on XDA to) that are complaining about the fingerprint scanner on the Galaxy Note 4 to be bad and inaccurate. Well, i'm here to tell you that it's not the fingerprint scanner on the Galaxy Note 4 that is bad or inaccurate, but it's your way of setting the fingerprint scanner up that is the problem.
I have set up my fingerprint scanner up correctly and it works extremely good. Just follow this guide and you will be all fine. This video is not made by me by the way and even if this shows the setup process for the Samsung Galaxy Tab S tablets, it still works the same for the Galaxy Note 4.
I also added a poll about the fingerprint scanner in the post here. ONLY answer it after you have correctly set up the fingerprint scanner according to the guide in the YouTube video and after you have given the fingerprint scanner some tries, thanks.
Have a good day.
Hmm well I have watched your video but I think you missed out what is causing the unsatisfactory experience.
If you are unlocking the phone supported/two-handed, such as in the video, phone placed on a stationary platform such as a table and you swipe your finger; or your left hand holding the phone while your right hand swipes the scanner - it isn't exactly a convenient feature. If you are unlocking the phone 2-handed, there isn't a lot of difference from unlocking using PIN.
2-handed unlock is 99.9% accurate for me - same as the iPhone 6/6+'s one-touch scanner. However, unlocking one handed is another matter. The phone will prompt you for a second set of 10 swipes after you done your first 10 - and if you did your second set of 10 supported on table or with your other hand, then you are likely to face issues unlocking single handed.
This is because the con of a swipe censor is that it is less accurate vs the one-touch version, and the drag of your finger/thumb while swiping distorts your fingerprint (because your flesh drags and there is pressure) according to the direction you swipe. The way you swipe 2 handed will be different from the way you swipe single handed.
I have no problems registering the first set of 10 with the conventional thumb downwards swipe. That is easy. But during the second set of 10 where I try to register one handed with my thumb swiping on its sides, there is a few hit and misses. I have eventually gotten used to it and accuracy in unlocking improved much, but for every 10 unlocks I can still miss 1 or 2 times. It is no wear near the accuracy nor convenience of the one-touch sensors.
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:
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.
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.
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.
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.
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.
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.
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.
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.
Maybe just register in the same-ish angles...
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.

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.
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...
Couldn't agree more.. Look at the poll... Clearly doesn't work like it should.

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".

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?

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.
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
I know 3t has a facial recognition features but it doesn't unlock fully. Recently, the 5T rolled out with an ultra-quick face unlock that really surprised me how quick it is.Do you guys think OnePlus should add this feature to the 3T ?
Its arguable. But the 5 already got it in the leaked Oreo build.
So its a maybe maybe situation.
Gravity Box for Xposed has an Instant Unlock option, i.e. the phone unlocks instantly when the correct password/pin is entered, without any further button pressing or swiping. Combined with the Smart Unlock option (Face Recognition), you get an instant face Unlock. It's probably not as secure as the 5T implementation, but it's pretty fast.
face unlock without special camera is just a bad idea, i can break my brother face unlock using my face on dark environment easily, and we're not twins
On my Mi 9T Pro, face unlocking has been very problematic, as I found out that my brother can also unlock my phone. This obviously does not speak to the face unlock's security, as I do not even look that alike to him. When I tried re-adding my face several times it continued to have the same problem, even when I went outside in the bright light to set it up, my brother could still unlock it. I have since disabled it as this likely means it is unlock-able to anyone with a similar face or even a piece of paper.
This is the case with all camera based face unlocking.
Not really, have tried the same with galaxy s8 camera face unlocking, and it doesn't have this issue. I don't think this should have been put in this phone if it as insecure as it seems.

Well there are some differences. Here and many phones are only using a cheap 2d image recognition method, which i would say is mostly only an unsecure gimmick.
additional security would use 2 cameras for a 3d face recognition. Still not as good as a fingerprint lock, but already pretty robust.
with an extra infrared projector it is also possible to recognize faces in the dark or in too bright places for regular camera images.
Here is a more indepth explanation
https://www.androidauthority.com/facial-recognition-technology-explained-800421/
I saw this while searching the phone and looked it up saying i can use it with sunglasses on. But when i try to register it says no face recognize. I'm wondering is this because of the type of sunglasses or you was there an update to remove this for security reasons since nothing out there seems to be in the last few months
hey,
I was just going through your post and came to know about the query. This is usually due to the sunglasses as the sensor scans the retina of your eye directly. So as the eye gets covered that's why the phone cannot recognize it.
obliged!
...and this is where miss the 3D face recognition from mate 20 pro...had 2 faces registered (don't you dare call me two-faced!) and it worked fine with sunglasses, even with the option "open eyes only".
So I perfected the fingerprint recognition,trying so many times that I get <1% errors these days.
Samsung face unlock is not secure anyway.
BTW..."Scans the retina"? You wish. It's general face recognition, that's why it can be fooled by placing your picture in front of the FFC.
