Hello,
So I have been really wondering do we have an proof that fingerprint sensors learn and adapt to improve finger print recognition? It is stated by every manufacture but never seem and proof of felt any proof of this.
If anyone has any info I'd appreciate it
Thanks!

I personally haven't had much of an issue with my imprint other than when I was trying to fool it by using other fingers or a spot other than the tip of my finger. I came from a Nexus 6 and before that a Moto X 2013 so I am very used to resting my index finger in the Moto dimple. I trained my index fingers on each hand and it works great for me. Some people who have had issues getting a read have posted about doing the learning steps (you scan the finger 5-6 times) to rotate the finger around and move the placement slightly up or down so that it can read more areas of your finger when scanning. I didn't do this, I simply tapped and removed my finger in the same position (holding the phone like I naturally would) and it worked fine for me. I can use the imprint with the phone sideways or upside down with no issues as well.
To answer your question, I had never heard of it doing that, and I'm not sure if it does. I'd almost prefer it not to because if it slowly warps away from what my fingerprint should be, it could make it more susceptible to someone else being able to unlock it. Definitely not an expert on the technology, so I don't know if that learning process would make it less secure or not, but seems like it could. Who knows..
Love my S8+.. however I think the biggest problem for me with the device is to get it unlocked without doing something very specific.
The iris scanner works fine.. but it has rules as far as how face the phone and distance yourself from it.
Are you guys also experiencing what I am as far as not being able to quickly unlock your phones from any casual position?
and to top it all, OK Google detection doesn't seem to work!
I agree I hate fingerprint scanners on the back. Tried to like them but never get used to having to pick up the phone when its laying flat on a table
Never use it anyways, just swipe to unlock. Not as paranoid as some are.
I really don't understand the bad press, I much prefer the new location!?
Before with my S7Edge if I wanted to one hand scan i had to hold the phone like a diving board, teetering out of my hand insecurely.
However with the new placement on the rear, i can middle finger scan one handded much more secrely with phone gripped between pinky, ring finger and thumb.
And finding the placement of the scanner is actually very easy to find if you use a case (any case for that matter...)
I sencerly hope people who are complaining with the new placement arent still scanning try to scan their thumbs because...that would be ludicrous!!, [emoji15anyways +1 for actiually liking the new location, a defenite improvement in my eyes of the S7 Edge.

No, i like it. Most of the time i use face unlock or smart location unlock though.
I find it hard to hit. The LG V20 I had before with the scanner in the middle was not bad.
I've gone to using the iris scanner instead. It is working much better then the fingerprint scanner. Especially when you turn on the option to bypass the lock screen swipe.
You can unlock your phone using: face recognition, iris scan, voice recognition and you can have it unlock automatically when at certain location (home/office) or connected to BT in your car for example. Paranoid types can save critical files inside secure folder and leave the phone unlocked. In other words so many options, to avoid fingerprint altogether, if you dislike it. Personally I don't care, may be actually easier to use it on the back, than front, especially when used one handed, but I have larger hands and bought smaller S8, it may be different for people with smaller hands on S8+
I do miss the fingerprint scanner on the front. When at work it is much more discrete and less obvious to unlock and tap to read a message/email/txt etc when my phone is laying on a desk in front of me.
Iris Scanner: Great indoors and if holding phone in hand. Worthless outdoors and if phone is laying on table/desk.
Fingerprint Scanner: Awkward all around. Placement, shape, proximity to camera etc. This is my only real gripe. It isn't that the S8 fingerprint reader is terrible, it is that the iPhone one was *very* good and placed ideally.
Face Unlock: Faster and easier than the iris scanner , but same drawbacks and less secure.
PIN: Ye' Ole Faithful. Still works just fine
As a v20 user I find the back placement superior to front placement phones. Its more natural and you can get a better grip on the phone when doing it instead of risking dropping the phone.
Putting the camera so close to the sensor was a pretty poor decision I don't know how that made it into the final product.

Wanted to be OK with it, but it's a PITA to be honest... And the recent update seems to have broken face unlock (probably works 1 time in 10). Iris scanning not that easy. I often have the phone on the desk to one side, and unlocking now means picking up the phone. Will have to investigate bluetooth pairing stuff, etc. Looking forward to sub-glass fingerprint reader (hopefully on Note 8)
Coming from a Nexus 6P I was used to it being on the back. On the nexus the placement was a bit better which made the access easier, but I like it nonetheless. I don't have my phone on the table a lot so no issues with picking it up like some other people do.
Yes. I wear glasses with a -15+ prescription, so the iris scanner is a complete non-starter for me. It won't even recognize my eyes through my glasses, and without my glasses I can't see the phone clearly enough to position my eyes for the scanner. The facial recognition is both not especially reliable and not all that secure, really. So, I'm stuck still using the fingerprint.
And having it on the back is a pain in the backside -- or on the backside, as the case may be. Even using smart unlock and trusted location, it's still a pain to have to reach across the phone and case when I'm trying to unlock the phone. The fingerprint sensor also seems to be considerably more finicky as to finger position than the S7's for some reason -- which is a bigger issue when I'm having to reach to unlock it from such an odd angle.
I honestly don't mind the position of the fingerprint scanner on the S8 - it's part of the reason I got the regular size instead of the plus. What I *do* mind is that it's a vertical rectangle - like, Samsung, nobody has fingers that can hit that when holding the phone like a normal person. If it was an oval shape I wouldn't mind half as much.
I've had to get a little used to its location over the past few days, but I find that my index finger tends to rest very close to it when I'm holding the phone, very easy to get to. I was used to using a finger on the back from the LG G4's power/volume controls on the back. I do find that it sometimes takes a little time, if you misjudge the distance and don't cover the entire sensor.
I've got a case on my S8 and it makes it easy to find the sensor. The fingerprint sensor was one of the (minor) things that made me get the S8 over the + because I figured the larger phone the sensor would be harder to reach. When I pick up the phone now I have my thumb near the power button and my index finger right over the fingerprint sensor. After I tap the sensor I just curl my finger so it supporting the phone from right under the sensor/camera. I probably have about a 75% first tap unlock rate.
I've never used a phone with a good front fingerprint sensor though, (only the note 4 with it's unreliable swipe sensor,) so I don't have much to compare to.

OnePlus 3T front fingerprint sensor is like the Note 5's but 1000 times better. No stupid clicking/moving button. It works instantly with the screen off or on. It works no matter what angle you use to touch it. It can be remapped to do many different things. It works first time everytime for unlocking the phone and unlocking apps.
When I first picked up the s8 I didn't think FP scanner was a good location. After 5 minutes using I feel like it's perfect. Mine also unlocks with the slightest finger touch and instantly. My note 5 was awkward at best unless laying on a desk. I do understand what you're saying about it laying on it's back. But I never hit the camera and it's snappy. I give it a 10

I really like the placement. It feels natural

I have the Gear S3 and use smart lock, so I rarely have to use the fingerprint scanner (or face or iris scanner form that matter) very often.

Honestly I think it was just for symmetry. To me there isn't any other logical reasoning (unless it's tied to the other electronics located there like the cam and heart rate sensor)

So a few of youare going to roast me over this but never mind.
If I am willing to discard the Fingerprint scanner on my Oneplus 5 and install the OP5T display ( Which is a beauty) . Can it be done? I haven't seen the blueprint or thae layouts but is it possible.
Please be kind.
Respect.
I think it won't be possible from software side. I fear that you should flash oneplus 5t firmware (bootloader??) so it will recognize wider screen properly. I fear you will only end up with hardbricked oneplus 5½t, if you still manage to try it. Keep some kinda blog awake and tell us what you did, how and share some screens
Sounds more troublesome than just buying a OnePlus 5T.
The biggest problem will probably be that the screen of the 5 is mounted upside-down, which caused the jello-effect some people complained about. With the 5t, this isn't the case. So you'll have a hard time connecting the screen to the motherboard. Also, I believe the dimensions are really similar, but not the exact same, so it could be that the screen won't fit at all or that there will be a lot of tension on the glass.
And, as @Vika__ already noted, software will be messy as well. You would probably need someone to write you a custom firmware, although you might be lucky and just be able to use the stock 5t firmware, because the components are the the exact same as with the 5, aside from the screen and the fingerprint sensor
And also using 5t firmware would break atleast second camera, not sure about first one. But it doesn't make sense to throw away camera, fingerprint sensors and maybe even whole phone to try to get 0.5" more screen
Thinking about buying a One Plus 6T. Fine with no audio jack, teardrop, and I'm concerned about the inscreen finger print sensor. Since first generation technology heard it was slow, not as reliable as rear ones.
Wondering about people's one Plus 6T experience. Has software upgrades helped? Any technique for using it?
Mine was a little wonky at first, but worked good for the most part. Now several updates down the road I have no problems at all with it except every once in awhile if out in very bright sun light. But that's few and far between.
From my experience and experiences I have read the sensor is faster than a traditional rear one. Only issues I ever have is when my fingers are wet or dirty.
Finger print sensor and face unlock works just brilliant. dont hesitate to buy
I'll be the odd man out. I hate it. Probably 4 out of 10 times I hold my finger on it and nothing. Just glows at me, rather infuriating honestly.
10 out of 8 picks up. most probably you couldn't setup properly. you must setup same finger at least twice ?then will pick up super fast

works 10 out of 10 times for me with clean fingers in any light situation. I think how much part of your finger gets registered also matters. I try to cover the whole part above the first line of the finger.
Works fast enuff not to bother u.
Never will be fast like a traditional one which works instantaneously.
How fast it is :
Imagine the time taken for a double tap on screen.
Giving allowances for differences in speed of double tap amongst us,
It will not be quicker than a double tap.
It will not be longer than a triple tap.
How often it doesn't work :
Works everytime.
Special occasions it won't work :
After a bath.
It will annoy u. Make u do twice/thrice.
It's not wet fingers. Wet fingers work as fine as dry.
May be the salt depostion form soap or the soaked effect of fingers.
Comaprision to OP7:
Slightly slower than op7.
Op6t is at the border level - anything even slightly slower than 6t will bother u. Op7 has some margins.
But op7 has no mirror black.
Soon 6T will not be available.
Buy it soon.

Which rom do you use? And how did you register your fingers? (Light levels, brightness levels)
at first i had some issues with it, even after registering the same finger 3 times it didnt worked all the times and always took a while, but than i installed the mclaren edition animation and worked much better
So here's my two cents. The Finger Print Scanning is slow. I have a Nexus 6P and that's faster. But from personal observation I can say that the Fingerprint is a Hit or Miss. It depends upon a number of factors. My own case: on Stock OOS Open Beta with a FP animation mod installed (DeadlyGhost's. It's amazing. Do give it a shot. Can be found in the themes section) , I'm getting amazing speeds. I'm using a Modded version of the Ripple Animation (forgot the real name) and the color set to purple I only have to touch to unlock. This is with an Unofficial Third party case installed. While on a Custom ROM with the same setup (minus the animation) it takes a solid 2 seconds. So it depends upon your setup, I guess. Also as someone commented earlier the McLaren animation helps. If you're stock and U rooted there is a guide. Just search around XDA. If you're Rooted, try the aforementioned Animation Mod. Though it will only work on OxygenOS.
I switched from LG to this phone. I got sick of lgs late updates. I'm glad that I did. There is a lot of development here for this phone. Plus with the ROM, mods, etc this phone is the best daily driver that I have ever owned.
One trick I used was to only setup my two thumbs and one index finger.
OP6T only allows for 5 fingerprints to be setup. I use two slots for each thumb. OOS uses images to recognize your prints. By using two slots you add more images to the same finger which makes it even faster. Setting up the same finger twice can be difficult as it will take time because your print will be recognized, but this gives you the chance to capture your print at every angle possible.
Never found the sensor to be particularly slow.. it's faster than a iPhone 6s Plus.
When I bought this device I was a little worried like you, but trust me, the sensor is not a problem, is not perfect but neither horrible, it just works fine.

Are u suggesting animation mods help to bring about a faster finger print ??
My take : I don't think so animation has any effect. Theoretically it does not, since animation is only outside the fingerprint area.

9.0.5 ( not 9.0.15) OOS. Omega kernel.
Brightness level was average I guess. I dont think it matters since the sensor area is by default fully lit in high brightness mode and adjacent area are jet black while registering the finger print.
I tried dark room registering but in my case it didn't add any difference or I felt it was slower for one of my thumb . So I deleted it and re registered in my room with a tube light lit.
Did it two three times until the slower thumb became equal to other thumb.
I guess it was something in my thumb rather than lighting that made it slower.
One idea u can try is,
While registering wipe everytime before u place the finger ... I haven't done that. But dust on screen or print on screen guard is likely to interfer in registering.
And if still slow, no need to worry that others phone are good . Some people have good deep fingerprints.
I've never had an issue with mine. I did the trick (found on xda) to install the McClaren background and it to me appears to be faster than the stock background.
Another thing I've seen is if you wake up your phone and are looking at it, while pressing the fingerprint sensor area, it may appear to stutter when unlocking if you have face detection enabled also. I've tried it several times with a piece of post it note over the camera to verify that to me, appeared to be what was causing it to "stutter". If I am looking at the phone, I don't go near the fingerprint sensor. If I'm not looking at the phone, then the fingerprint sensor works lightning fast.

I concur. Sensor seems to work very well and very quickly as long as my thumb is clean and dry. If it isn't...I guess that is what the PIN is for.
No way a UD sensor beats or even comes close to a tradiotnal one for now. Traditional back fingerprint sensor in oppo f5 youth I have tested, in my frnds phone.
It instantaneous.
At first it sucked but improved over time.

So I love my 6T! Love everything about it, even the notch..
However, my fingerprint has been so spotty, sometimes catching, sometimes don't. I wash my hands a lot at work and sometimes it doesn't work on dry hands, and sometimes the weather makes my hand cold, and it doesn't work.
Basically, I'm looking to upgrade to 7T, since I heard the screen fingerprint reader is better. I mainly use it to unlock phones and apps, and for some reason (even though sources say I can use face ID to unlock apps), I still can't unlock them.
Is it worth upgrading to a 7T?
If you're looking to upgrade just because of the fingerprint sensor, I don't think it's worth it.
Now, granted you'll gain additional features (90Hz refresh, Android 10, etc.) but all in all, I don't think it's worth it unless you can sell your 6t for a good amount of money.
Do you use a screen protector? If so, what kind? I use this one: https://www.amazon.com/OnePlus-Prot...en+protector+oneplus+6t&qid=1571340845&sr=8-3 and it's great. No issues.
I'm also on the Beta Channel so I don't know if they've made any updates to the fingerprint sensor or not.
I work in a print environment so I'm constantly washing my hands but, again, no issues.
Hope this helps.
