face unlock & iris scanner

All the reviews I read prior to receiving my phone said Samsung utilized the face unlock and Iris unlock in conjunction together.... My device tells me I can't have enough both on at the same time. Was something changed or am I missing something?

Yeah you can only use one or the other in conjunction with the fingerprint sensor...

that would be ideal to have both face recognition and iris scanner working at the same time in case one or the other cant recognize you.

It they would work at the same time, iris scanner would never engage as face unlock is faster.

so awesome

Its one or another for sure.. From a Device user since a while..

Hmm maybe I was mistaken I swear on release day they were saying they included it to assist with unlocking when the Iris scanner isn't picking up the eyes fast enough... And the Iris scanner would be the option for when you're in pitch black situations

Iris scanner is useless if you wear glasses. Have to take off your glasses to use it.

I wear contacts and it works almost flawlessly. Sometimes I have to purposely not look at my phone because it unlocks so damn fast

Iris scanner is lighted with an infrared diode so no problem in total darkness.
If biometrics fail you can always unlock with your PIN.
I also recommend using the option of requiring a PIN when starting the device.
This is for your own protection in case your device gets seized at a checkpoint as you cannot be legally forced to enter a pin/password whereas biometrics (face/iris/fingerprint) you CAN be!

That wouldn't make much sense for security. Right now it's (biometric) from least secure to most secure face>fingerprint>iris
if the most secure can't unlock your method, why would it try a less secure method from the same general area?
they say to use iris for the most secure method. but then allow it to unlock with the least secure?
that would be like you try to login here and it says password is wrong (esdd9udskl%(_*$#1239) so then it just asks you for your first name instead to log you in.
Only way it could be useful is if the light sensor thinks it's too bright outside (where iris scanner doesn't work) then it can do face unlock only in those situations with a warning that it will use a less secure method.

Face recognition will recognize you faster than iris every time.
The point of having the exclusivity is to have the user choose: ease of use or security
For the fraction of a second difference, I'll be choosing security with iris.

iris has been working so well for me that I see no reason for face unlock. Only time I had an issue was outside when bright and also wearing sunglasses.
Problem is, if it's bright outside, I'm wearing shades.... and when I'm wearing shades, face unlock doesn't work either lol.
another thing with iris is if the phone is too far away, you gotta bring phone or face closer to the other. (this week's example is I'm in class and trying to unlock phone under the table and it's too far for my eyes to be recognized).
if you know there is gonna be an issue, just touch the fingerprint sensor. it will open screen and unlock.

I would think glasses would give issues because the ir light would reflect off the glasses and not brigthen up the iris

Yeah you're right but I didn't think into detail I just swore that's what I read. I swear all the head lines were like "Samsung to include face scan because Iris scanner not yet up to par" that made it sound like to me they would be used in conjunction

True. Lol. But the warning on the phone always warns about contacts and glasses... I think it's for the thick colored ones that's the issue though.

Both face and Iris unlock suck. Finger is in a bad spot. FML

Iris is working phenomenally for me. I haven't used face yet though. I haven't had to use finger but I have a otter box on so I can feel right where the scanner is and my pixel kind of got me used to back scanners.

Iris unlocking and sun glasses

Just noticed that my phone unlocks itself by scanning my irises even if I have my sun glasses on???
Maybe the scanner is too powerful I thought...so I covered one of the lenses with my hand...and tried unlocking it again...
And it did...it unlocked by scanning just one side of my face and with sun glasses on...
Maybe it is time to go back to the pin option.

Yup, one eye is all it needs to recognize.

Why? Matching just one iris is secure enough--and certainly more secure than a short PIN.

Yea just like the note 7 it works very well and fast

Face Unlock - Is it TOO permissive / Not secure enough?

I love how fast the Fast Unlock feature is... but I was curious as to how secure the facial recognition technology actually is.
I did a test today with my father and my brother-in-law try to see if they could unlock the OP6 with their faces. My father and I look relatively similar and my brother-in-law, while there is no blood relation, has similar facial features.
To my surprise, the Oneplus 6 unlocked for both of them! I removed my current face profile, set it again, and have them try a second time and the phone unlocked again.
I'm going to continue to experiment with this with other friends (one's who have similar features as well as those with distinctly different features) and see if I can continue to reproduce these results.
Community: Has anyone else experimented with this? If so, what was your result?

Interesting [emoji106] will watch the thread... The technology should be similar to the oneplus 5t so maybe there your will find some more info?

Was it not because you were near the phone and that it also saw your face when they tried to unlock it?
I never heard before that someone could have fooled the phone with face unlock.

Yes, it's not secure. My friend picked up my phone and it unlocked. ?

Just tried it and surprising yes, it seems other people can unlock mine with their face [emoji50]

that sounds strange.
Mod Edit

I tested it out on my daughter and she was able to unlock it with face unlock. It's not very secure.

If you're worried about security don't use biometrics.

Without dual cameras and 3d rendering face unlock is not secure

Hmm not secure indeed on op6. I tested and keep my hand on half off my face and it still unlocks. On my 5t it works way better? Disable face unlock till issue is solved, I thought that oneplus said that face recognition was improved on op6.
Regards ysco..

Yupp, I removed it.. When my father just took the handset to admire the outer body and it unlocked within 2 seconds when he pressed unlock button.. I tried it again and it unlocked again.. So I removed this bull**** from security..
I thought , one day I will find my dad reading my sex chat.. Prevention is better the cure.. I just removed it without saying a word.. ????

No, was not next to him... I locked the phone and handed it to him across the table. He pressed power and the phone scanned his face and unlocked.

I think OnePlus's "fast" face unlock is much worse than stock. It just traces out the rough geometry

Yeah, that's why it's so fast. It's not at all secure, more of a gimmick.

Dont care much for security....but är missed the lockscreen too much, had to dissable Face Unlock again

My dog unlocked my OP6, what does say about me? Lol, I'm one ugly mofo or my dog is one handsome poodle.

You're ugly

It seems like everyone who has replied is ok with this?
Just makes me wonder what other features and solutions are gimmicks... What else did they skimp on...

I thought OnePlus already mentioned that the face unlock is not secure.

I turned off Face Unlock because it was so fast I could never see my notifications. The fingerprint scanner works well enough for my taste.

Touch screen stoped working

So I droped the phone into water. And you should always turn off the device and let it dry. The problem was that the phone turned on and off itself. 2 days later when I have let it dry, I can start the phone. There is a bit of misscoloring on the screen. But when I try to enter my password, it doesn't recognize my finger. One time the screen changed like it was recognising a finger but that was only for a split second. Do you think the chip is dead? Can I remote control it somehow? I have rooted and have twrp installed. Thanks for answers

From what you say, it's damaged from water, one thing you can do is to buy a replacement for the FP sensor.
Still, wait a couple of days, it may begin to work properly again.

eBay, or something. Just type honor 8 fingerprint sensor. Buy you must teardown your phone like that.

There are many websites, like the one mentioned in the previous post.
However, I advise you to take to a repairman to replace it (if you don't have experience with this sort of things)

I don't really understand what the fingerprint sensor have to do with the touch function on the screen.

It's my bad, when you said the chip and finger in the same sentence, I didn't see the screen part.
I apologise, my bad.

Facial recognition fails more often than works.

Title pretty much says it. I even added two different faces angles for recognition. I'd go as far as saying seldom does it work.
Anyone else having this problem? Anyone know of any thing to do to improve it?

Try taking a scan with a mask on

Face unlock on phones with just camera is not safe.
Since you can use a pic of yourself to unlock the device, so never use face unlock unless the device uses more advanced technology to scan your face.

Are you doing a scan with the phone straight in front of your face and another with the phone held about chest height?

I've actually tried this on the N20U and can't get it to unlock with a picture.

Then you aren't doing it right. It's been proven with devices with just camera to unlock can be bypassed with picture of yourself.
Here is an example video of proof:

Here's one with s10 face unlock bypass.

Yes, I did the two scans.
I am not expecting it to work when using a mask.
Sounds like most folks are not having issues with it. I will try a new pair of scans

Taking a picture and holding it in front of the phone isn't difficult, I even got the vibration when it didn't recognize the face. Have you tried it?

No, but to how unbox therapy did he had to move picture forward and backwards at the phone until it recognised the picture and then unlocked the device.
So make sure pic you got isn't to dark and has well lit face and that camera can see picture well, otherwise it won't work.

I've probably spent about 20 minutes trying to unlock it taking several different pictures with 3 devices and at least 50 total attempts and I haven't gotten it to unlock once. It may be possible on these but it seems like it isn't going to be very easy. Try it and see what happens.

Facial rec wouldn't be of any concern if only the Smart Location worked consistently. It fails more often that it works.
I saw a suggestion on older devices to put the pin on the location map in 4 places around the home. But the current softward doesn't allow that. At least I couldn't get it to work.
Then there's finger print unlock. That's a big pain too.

This issue is really annoying. The suggestions to fix never work. i.e. taking new pics, or high/low light pics. I've tried everything to no avail. (OneUI 3.0 Android 11, N986B)

Well, I though that photos do not work to unlock the phone, I have an Iphone and face id there works just with my face, and it is always in attention mode. So if I do not look on the screen it doesn't work. Seems prety advanced to me.
p.s I don't know about samsung

On iPhones its different technology for face unlock. They use infrared or some face scanner technology. While Android phones with software facial unlock by using normal camera isn't as secure than what Face ID is on a iPhone or an Samsung galaxy s9/note9 has got.

Agree, but it shouldn't be SO terrible. It works pretty flawlessly on Huawei P30 Pro, but then can't make it too tricky to send private details to the PRC
