Face unlock - shaved vs bearded face - Samsung Galaxy Note 8 Questions and Answers

Hi guys, I use face unlock as my main unlock method but often the phone struggles when my beard grows a little long. Is there a way to get the phone understand both looks? I have the less secure option already enabled but would be good if the phone can learn that facial features can change over the weeks.

{HOW TO} - TIPS for improving fingerprint scanner on galaxy s5

HELLO FRIENDS
THIS IS MY FIRST how to THREAD SO PLEASE HAVE SOME MERCY ON ME
I HAVE TRIED THESE TIPS ON MY GALAXY S 5 SM G900H VARIANT AND I AM 100 % SURE THAT THESE VERY SMALL BUT HELPFUL TIPS WILL ALSO HELP ALL OTHER MODELS TO IMPROVE THERE FINGERPRINT SCANNER
1 JUST MAKE SURE KEEPING IT IN STRAIGHT DIRECTION
make sure that you have kept it straight
i know not being able to use the fingerprint scanner with one hand is a pain but if you adjust that way the you’ll have much more success and comfort with it
2 USE THE SCREEN ALSO FROM UPWARDS
i asked some people that how they use the fingerprint scanner and was shocked to see that many dumb ones don't use the screen mentioned above main button which holds the fingerprint scanner in it
so please start sliding finger right from the upper tip of the dotted space shown on screen to get good results
3 REGISTER SAME FINGERPRINT PATTERN TWICE OR THRICE
this is the master trick for improving accuracy believe me friends
in our s5 we can register up to 3 fingerprints { I BELIEVE IN FUTURE THROUGH UPDATE FROM SAMMY WE CAN GET MORE }
register the same pattern thrice and believe i get less error while unlocking the phone by fingerprint method
THE LATEST UPDATE ALSO PROMISES OF IMPROVED FINGERPRINT SCANNER AND HEART SENSOR
I CANNOT MAKE SURE OF FINGERPRINT SCANNER BUT HEART RATE SENSOR HAS BECOME MORE PRECISE THAN BEFORE
SO MY FRIENDS PLEASE TRY THESE SIMPLE YET HELPFUL TRICKS TO IMPROVE YOUR FINGERPRINT SCANNER AND SEE IF YOU GET SOME GOOD RESULTS
HAVE FUN WITH MINSTER GALAXY S5 :good::good::good::good::good::laugh::laugh:
A SIMPLE THANKS BY YOU IS ENOUGH FOR ME
TL;DR?
Debloaded guide:
1.Keep it(???) in straight direction. (?)
2.Drag finger on screen and downwards, as instructed.
3.Record more patterns.
:good:
Tips from me.
You can register several fingerprints in one "pattern", every swipe you do that is "successful" is recorded and will work fine. 'If I remember right there is 8 or 9 swipes, that will give you some room to have several prints in one "save".
Don't do the same swipe over and over, do some variations and you will have a easier time to unlock.
I recommend you do your thumb in a one hand grip aswell as your index-finger in the two and grip as instructed(but only use that one as a backup if thumb happens to fail).
I really don't see why people have such difficulty with the fingerprint scanner. Straight line down, not too fast...
LOL ?! I see no sense from this post ! Please close it !
The scanner is already pretty accurate. I can use three different fingerprints.
And i think the title sould be " How to use the gs5 fingerprint scanner properly."

Thanks guys for corrections and info
I will keep such things in mind

Is there any way to register more fingerprints?
Id like to use both my tumbs and both my index fingers, witch is 4 on total and we are limited to 3...
Quick question about unlock with the scanner - Is it possible to have the scanner unlock activated but also show a pattern/pin code unlock on the screen?
The reason i ask is because i have read that sometimes it isn't that accurate and so instead of just keep trying to use the scanner, i would just unlock it with a pattern
Mine always works, I must say though, the fingerprint scanner on the iPhone 5S was MUCH better and MUCH more accurate:crying:
I think so to,and more practical because you dont have to swipe your finger. I do have to say that i was expecting it to be less usable and it works better than i thought but still not at the same level as the iphone.
Anyone knows if there is a mod to have the screen showing the pattern unlock also? Just because sometimes the fingerprint doesnt work and i dont like the password metendo, so it would be more practical to just be able to unlock with pattern right away
Just to add a little to this. I've never had a problems getting the scanner to work and was pleasantly surprise as to how good it was but having to swipe down makes using it one handed a bit of a pain and I was searching to see if there was any mod to be able to swipe up without any luck though.
Then it dawned on me that down is only from the phones point of view so I now just flip the phone over as I press the front button to get the lock screen and can then use my thumb to swipe up to unlock the phone then spin it round again as the phone wakes up.
I have of course registered other digits so I can unlock it normally but being able to use it one handed increases the use for me quite significantly.

Anyone use the fingerprint scanner while having a case on the phone.
By the way fingerprint unlock also works perfectly when swiping up and holding the phone the right way up! ☺
Nice! Helpful thanks
working fine for me...
Mine is hit or miss....sometimes fail sometimes accurate...
Is it possible to wake up and at the same time open by using only home button....becoz for the first time im testing it on my galaxy s5 running lineage os 14.1.
Pressing home button while swiping is always fail to ooen lol...is there any way to fix this....
I want the way like s7 fingerprint wake and unlock with just preeaing the home button....

To anyone who thinks the fingerprint scanner is bad / inaccurate

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?
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.

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

OnePlus 3T Face unlock? share your opinion

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

Anyone else have security issues with face unlocking?

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

Any way to make face unlock work on p5?

Love having a finger print reader on the phone but do miss the face unlock in certain situations like if the phone is in the car cradle or sitting on my desk. Any way to add it? Not sure why we don't have it. Used a oneplus 8 for 2 weeks and it used the front camera to unlock the phone.
IIRC, OnePlus added face unlock to the OP3/3T through an update without any special sensors so maybe it is possible, but it might not be the most secure form of unlocking.
While a lot of people seem to like it, it's an awful form of security.. Maybe that's why they've decided to not use it, I know I wouldn't.
Iris sensor FTW
