[Q] Replace Note 4 Fingerprint Sensor with S6 Fingerprint Sensor - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi, as I stated on the title, I would like to discuss about the Note 4 Fingerprint Sensor and if we can replace it with S6 Fingerprint Sensor. Initially, I have 2 concerns, which are software and hardware incompatibilities.
A few weeks back, I flash my Note 3 with Darklord S6 port ROM. When I was setting the device up, it promoted me to set up the finger print scanner like the way the S6 asks, so I thought if we port the S6 ROM to the Note 4 it will change the way the sensor works and I no longer need to do the swipe gesture.
However, after a bit of research and discussions, the problem lies within the hardware, so even if I port the S6 ROM, if the hardware does not support it, then it is no use for the software.
But, I have looked around on Ebay and other sites for Note 4 and S6 sensor. They look very similar in shape, but I am not quite sure about the exact dimensions (May be someone in this forum who has 2 devices can do the measurement for me ;D). So I am thinking if we can replace the Note 4 sensor with the S6 sensor and port the S6 ROM to the Note 4, would it technically solve the problem and now we can have the Note 4 with S6 sensor that works like a CHAMP?
If someone has already created a thread similar to this, please let me know and I will delete it or the mod can do it too. This is my 1st post so sorry in advance if I cross some lines
**Disclaimer** Please do not try this idea on your devices if you are not a professional. I am not responsible and cannot be hold accountable if you break your devices. Good day!

Even if you replace the sensor, there's still the software that would need to be reprogrammed in order to utilize it properly. You wouldn't be able to simply replace the sensor and expect it to magically work.
Just saying.

Yeah, I think the swiping fingerprint scanner is part of the security software developed by Samsung earlier on. While the fingerprint scanner on the Note 4, Note Edge, SGS5, SGS6 and SGS6 Edge are probably all the same sensor. It's the security software that would have to be updated in order for it to be used like the SGS6/SGS6 Edge's fingerprint scanner.

S5 fingerprint scanner like iphone? (Without swip)

Is there any way we can tweak the fingerprint scanners unlocking procedure without swipe?
Because its a pain using fingerprint scanner one hand. Thanks!

No. The iPhone can do this due to the shape of the home button, and the amount of the fingerprint that can be read without movement because of that. The shape of the home button on the S5 works against this as it only reads a thin strip of the print unless you move the digit.
The only possibility I can think would be a hack to reduce the amount of the fingerprint required for a positive ID. And even if that was possible it would by it's very nature reduce the security offered by the fingerprint reader which could cause issues with the Paypal certification.
Perhaps the videos I have seen were overly simplistic and I'm not getting my S5 until Friday so can't speak from experience, but using the thumb to unlock looked a simple procedure to me and easy enough to do one handed.

Do you miss not having the fingerprint scanner on the front?

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)

Fingerprint sensor

How to improve the quality of the fingerprint sensor on the C9 Pro?
i am planning on buying this phone. is the fingerprint sensor really bad on this phone??? and is thefingerprint sensor made out of glass or plastic and does get scratched easily like s7 edge. i am questioning insead of answering sorry but i appreciate your reply...
No! The fingerprint sensor is only less sensitive than other models.
Less Sensitive! are you implying it doesnot work perfectly while touching the sensor but works fine while pressing the sensor/home button??? And does the fingerprint sensor easily gets scratch on it?
The fingerprint sensor works very poorly, worst of all the smartphones I had. While touching the sensor works fine or wrong (more often wrong).
The fingerprint sensor don't get scratch on it.
How long have you had your phone if its still under warranty you could have it checked near your local samsung customer care and thanks for the info Xd (keep us updated if you can)...

Device Modification Query (It 's just something that popped up in my mind)

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

Galaxy S8 fingerprint scanner is a trash

Hi,
Does anyone know how could Samsung or its supplier produce such a bad fingerprint scanner that the S8 has? On cheaper phones like Xiaomi or Huawei the FP Sc is quick like hell and it is almost doesn’t metter how you place your finger on it. But in the case of an S8 it is not only in a bad position but it works so badly that in many times it unlocks the phone after the 5th try or so. What do you think? Is this the fault of the software or the sensor? Wasn’t that a shame to Samsung to release a phone like this? Or nobody cares if they get a gorgeous screen?
Mine works fine, its your finger.
There's an easy fix for it, just don't use it
Exactly my thought! I had to put my finger 3 times on average to get it to work. sometimes it just vibrates and doesn't work. I know its not my finger being dirty or incorrectly positioned because it happens many many, many times in last 3/4 months.
Mine works fine too, unlocks at first try unless my finger is dirty, I have this phone for more than a year.
Its just you buddy
It is prone to scratch. Daily fine dust can easy put scratch on it during finger scan. Check yours for scratches.
yea it is true, i come from huawai p10 lite and was so fast, omg.. and now i have s8+ and fingerprint from my opinion its a trash. i have to put 2 3 times to work, and i will sell it becouse evry time i have to clean that stupid camera to make a photoooo oh samsung what are you doing to us
