Is it me or is the fingerprint implementation a little lacking?
First when phone is powered on it won't let you use your fingerprint and requires the less secure Pin to access the device the first time which I find retarded
My second biggest issue is seems rotation isn't taken into consideration for fingerprints.
What I mean by this is if you setup your print and your finger was vertical if you try to scan your print later but your finger is horizontal it won't take it
I mean it's the same print so the device should be able to recognize it 360 degrees.
Some may argue that a print horizontal and vertical are technically not the same print which is true but I argue it's IMPOSSIBLE for a fingerprint to match someone else's just because of rotation.
My fingerprint at 45 degrees will neveratch stone else's at any degree. So rotation should be considered
My work around is to setup all 4 possible stored fingerprints. 2 for each thumb and each have 1 vertical and one horizontal
Maybe I'm being silly but stil bothers me
Maybe you got a defective unit. My fingerprints work 360 degrees.

I tested different roms other than stock and same issue
Not sure how hardware could be at fault if it works if I program the fingerprint.
Do you have the PIN thing at boot?

Every device asks for the pin/pattern/password on first boot, it's the same on Apple products. As for the fingerprint, I can hold my phone upside down and it will recognise it.

I dont get why a device would ask for a less secure mode of authentication when a more secure one is programmed
thanks for your info

A fingerprint is not cryptographically secure and it's much easier to "crack". For example you get arrested and the police wants to search into your phone. There are many countries where the police doesn't need a warant to do this, they can just force you to put your finger on the scanner. This goes for thieves too, they can use force to unlock your phone. So a password or pin is technically more secure.
Edit: another big reason for this are the unfortunate events when someone can lose their hand or fingers. The only way you could unlock the phone this way is to hard restart it and use the backup password.
And it's not a very big deal, I doubt you restart your phone every few minutes. Mine for example has 5 days uptime at the moment.
U can assign your prints many times from different angles. As for having to enter the password from reboot yeah I found that less secured. My solution on mine s7 edge is having password lock on the SIM card so there's a double lock when ever my phone got a reboot.
I have registered two thumbs and two index fingers and the fingerprint scanner accepts them even if I scan them up-side down, so there might be something funky going on with yours. Delete your current prints and do it again. This time, don't just press the scanner in the same area, but move your finger so it gets your whole thumb, and also rotate your finger a bit while it scans.
I just rotated my fingers a bit between scans. Problem solved.

A read a few years ago that some hackers got into the iPhone when fingerprint was enabled. They could only get through the first lockscreen right after boot. I THINK that is the reason for the pin, as that is way more secure.
Yep, it does work on all angles. But you should do more than one fingerprint profile, even for the same finger. When creating a profile, you need to move your thumb around to cover the whole area of your thumb, otherwise you won't capture enough for it to work on all angles.
1. Requiring a pin or password after boot is an additional security feature. How often do you power down your phone and then start it up again?
2. If you rotate your finger while setting up the password, the phone will recognize it rotated later.

In my experience, two of the same finger will drastically mess things up. Unlike the iphone, where it helps. Try with just one of each finger.
I agree with the OP on the Fingerprint, But for me its not a issue.
All i done, was go into the finger print and added my same finger multiple times from every angle.
The Rotation of the finger was a issue ONLY when i setup my thumb holding the device properly.
I think it has more to do with the overall % of the Thumb area it was able to capture.
So rotating 90 or 180 may miss off 25% of your original scanned thumb, making it incomplete.
I added my same unlock fingers about 3 times, one of them uses just the edges of thumbs, the other uses the Flat part and Top
the over uses Flat part and bottom.
So when i press with my Thumb, it recognises my Half-pressed Thumb print, or even just the top segment.
The Eneter your Pin on Reboot is stupid, But would not suprise me if there is a Mod to alter this behaviour.
It was adapted from Apple i think, when they don't the first fingerprint release you had to do the same on apple on first reboot.
(It seems more secure on the fact if your drunk and unconcise someone can turn your phone on and access it with your hand)
A good password before allowing the fingerprint scanner on a restart is a security option to encrypt the storage. A fingerprint isn't that secure as you think. It was recently been proofed vulnerable simple by taking the fingerprint (eg. the fat film on the touch display) and print it. You just have to use magnetic ink.

Much more secure would be a vein detection fingerprint scanner. Besides the fingerprint itself it detects the individual vein structure and flow what 1. isn't noticeable from the outside 2. needs you to be present (and alive)
BUT as said before: Different countries police is able to force you to give your fingerprint - This would be an issue if there wasn't an option to ask for the password (and pin) before encrypting the device on startup. The only what you have to be trustful is the phone manufacturers firmware. The strongest password is nothing, if the manufacturer failed with firmware.
This is indeed only just theoretical, because most people for sure haven't that much of a interesting contend on their phones.

I find the fingerprint scanner to be completely rubbish with my thumb and ok with my index finger. I even programmed all four on the same thumb, all with the phone being held in the right hand, and must have "scanned" every part of my right thumb from several similar angles, so there is no excuse for it not getting it right every time, and yet, I would constantly be timed out 29 secs 59 secs, 5 minutes... VERY VERY annoying. So it seems my right thumb isn't samsung fingerprint scanner friendly (it's not like I do a lot of diy or wanking or something!!) Index finger is ok, but then it is not friendly to use as I have to hold the phone in my left hand to then scan my right index. I suppose I could use my left index but the point is I cannot use my S7e fingerprint scanner with one hand as the thumb does not work.
A simple way to overcome the fingerprint
would be to inbuild a temperature control and only accept a fingerprint at the provided with a temperature of: 37 degrees Celsius
Again its still possible to overcome, It just starts getting expensive to be able to do so.
(Anything can be overcome, its just about how much time and money one may have)

But what If I have the flu? What if I've been in the sun for a while, and the surface temperature of my skin is above 37 degrees? What happens during winter when it's the opposite?
Back to the lab I guess!

Actually would not think so, With some clever coding or even using the latest AI's
You could implement something easy enough.
Using something like current GPS and Weather to understand the conditions it may be faced with.
Understand when your ill your Temp does go up and down, but not a great deal and it would not be hard to implement the differences in the temperature control.
To be able to tell the difference between a human temperature and Synthetic, based on how quick the temperature is reached, how its maintained and pressure sensitivity
All your doing is adding a layer of security of Magnetic printers.
So instead of it costing around 500-1000 to bypass a fingerprint reader, its going to increase that by alot.
Making it less affordable for your average Joe.

Hahah, yeah so this is making a thing that's not that complicated, extremely complicated. The current fingerprint readers are secure enough (for now), so no reason to go overboard here :laugh:
Also, temperature is not a constant. It changes all the time, so temperature reading is absolutely not the way to go. Fingers, eyes, ears and toes are mathematically unique, in the way they're one of a kind on each person, and can't easily be faked. Temperature is so incredibly random that it would never work.
A reader that includes a capacitive surface that rely on the electrical properties of the human body to detect if it's human (like a regular touchscreen), is easier. That way, it needs to be a finger touching, and not a piece of rubber or paper. Maybe it's already in place, I don't know, and I haven't tried to unlock any devices using paper or anything.
Hello,
Is there any options to have an active fingerprint scanner in our S7/S7E without root like in A5 2k17 or S8?
I just download "Always on amoled" available in play store, and with this app i don't have too click on home button to wake up my phone....but that app is not good enough for me.
up
Super Man rom have this feature however it is buggy works for a while and goes deep sleep. This is hardware / driver specific fault maybe someone will manage to port fingerprint scanner driver from 2017 A series.
I think Always On Amoled app is decent enough
Face unlock currently requires a double tap, which is annoying because it doesn't work half the time
Even though they are trying to fix this in the next update, a better implementation would be when you raise the phone, it shows the lock screen (not ambient display screen), and simultaneously turns on the front camera to face unlock your phone
Gravity screen can do this, but requires a heavy wakelock to do so. Using the same 'raise to wake' method as ambient display [which seems to work without a heavy wakelock], but then showing the lock screen instead of ambient display, should achieve this
I would LOVE this feature, it would be a complete game changer!!
I use gravity screen and don't lose much battery
Use the power button since it's more reliable anyways ?

There's still a fair amount of battery loss. Oneplus raise to wake seems to be able to do the same action without any battery loss
This was so fine on Op5 and 5T. Open Beta, of course!
Update: I've installed the wave up app. It basically wakes the phone when proximity sensor is uncovered
So when I take the phone out of my pocket, it authenticates my face automatically and unlocks, in a split second. I don't need to touch anything
Similarly if I keep my phone face down on a desk (not ideal), when I flip it over to look at it, it unlocks.
No messing around with d2tw which is more like quadruple tap to wake since this functionality is broken

Hi i use the original flip case from OP and as soon as i open my case door it unlocks witch is very easy and convenient.
Shall check with tasker.
Update: could not succeed.
I face no trouble in dt2w it wakes as it's intended to and unlocks with face within a split second, face unlock has become slower since the 5.1.9 and in dp3 but still fast enough
If my hand is dirty i just say Hey or Ok google.
Agree. it would be a great thing
Hello guys
I've ordered my Nex and cannot wait to get my hands on it (Hurry up gearbest!).
One thing bothers me:
On a youtube video I saw recently the reviewer mentioned that the display of the nex is super amoled. He then explained concerns that if the fingerprint logo - to show the position of the in display finger print reader - is always visible on the display this could result in a burn in on the Nex display.
What are your thoughts about this?
Thanks and BR
It's not always visible, only when you need it or when you shake your phone.
"to avoid burn-in is to ensure that your display doesn’t show the same thing in the same place for LONG periods."
So does the Nex have a pocket mode which prevents a wake up? - I mean this thing gets moved a lot in the pocket.
I would say yes but im not sure where ...
In constant movement the scanner is off.
This phone has a sensor that detects when the phone is near your face and shuts the display off when your on a call. This same sensor knows when your phone is in your pocket and prevents the fingerprint from turning on when in your pocket.
How accurate fingerprint reader is for you? Does it work fine or is hit-and-miss?
Moreover, is it active all the time, even when screen is off? Or I need to turn on screen first then put my finger on scanner?
Jerry Rig Everything has some details about it: https://www.youtube.com/watch?v=0SqEY8j91tk&t=5m1s
Optical fingerprint scanner which needs illumination to work. It works well in the stock ROM, however, some alternate ROMs struggle with the illumination and therefor struggle with the scanning.
