Galaxy S8 / S8+ users, do you use your iris scanner at all?
The Samsung Galaxy S8 has two unique mechanical components that are used for unlocking the phone — an awkwardly placed fingerprint scanner and a pretty straightforward, fast-working iris scanner. The latter one we first saw on the Galaxy Note 7 and were already acquainted with the tech. However, now, even months after the release of Sammy's latest and greatest flagship duo — the S8 and S8+ — we can't say we are fully accustomed to using the iris scanner exclusively for unlocks.

We are pretty sure we are not alone in this, but also certain that there are people out there who like and use the iris scanner on a regular basis. We thought “Hey, why not ask?”. Let's see who uses what to unlock their phone most often!

How often do you use the S8's iris scanner?

Almost always
28.02%
I switch between the different unlock modes depending on situation and grip
26.93%
I use the fingerprint scanner (almost) exclusively
28.99%
Trump card! I use the face scan!

Funny enough both of them kind of flawed and can't truly replace each other or even compliment. One's location is awkward and the other you can't use it in the dark, while you active or wear glasses( limited use) .

Are you sure it doesn't work in dark? My friends who got S8 have a different experience. It does work in dark and also with glasses on as per them.

It does work in the dark, due to it using IR, hence it doesn't rely on ambient light. nebula is just talking out of his a**.

If I talk from my ass then your face must be near it . I tell facts you talk nonsense.

If you claim it doesn't work in the dark or with glasses, you're just parroting instead of sharing your own experiences. That's not stating facts, it's using someone else's words as facts. I have the S8 and S8+ in front of me and I have glasses. Guess what, the iris scanner works fine. Even with glasses AND darkness. There, your "facts" disputed.

Of course everyone is wrong and you alone are right because you have both S8 and S8 +. I don't have to guess I rely on FATCS and real life usage that comes from users across the world. The fact is being die hard fan takes away sober mind. Suck my toe!

Hey nebula, I own the S8+ and 90% of the time it works in the dark.

Hey Jason. I am glad if works for you. Some people say 60%-70%. . Peace .

What facts when the real users around me (my friends) say it works and they r using it. Should I believe the internet where we can find anything or should I believe real people around me. However, if you believe the internet, here's the video. https://www.google.com.np/amp/forums.androidcentral.com/samsung-galaxy-note-7/708166-iris-scanner-works-darkness-video.html%3Famp

That's true IR technology can work in the dark. My mistake. I apologies. Also sorry you had to dip you face into my crack :)

You're mom was already there, I couldn't "dip it" even if I wanted. Anyways, it's always a pleasure when you shut down a troll and prove them wrong, as they always come with the lamest comebacks someone could see on the web ;)

Just don't buy Samsung toys anymore. They are high tech toys specially made for under aged teens and kids. There are much more meaningful alternatives for low prices as smartphones these days.

Yes I am. I have seen many reviews. It has been stated it does not work well in the dark. Reddit there is a lot talk about it too that comes from reall life use. :https://www.reddit.com/r/GalaxyS8/comments/62exue​/does_the_iris_scanner_work_with_glasses/ By the way I am not here to bush Samsung fan base just being honest like with any other smartphone I come across.

You're an asinine liar, it works perfectly fine in the dark just like the Note 7: https://youtu.be/RHHe5UVn08E

First four replies from that reddit ( https://goo.gl/6haxMr ): "The iris scanner on my note 7 could work through my sunglasses. It wasn't as reliable (I might need to move around to get the right angle if there was a sun glare), but it definitely worked." "Can confirm, Note7 survivor. Works with sunglasses/in the dark." "Facial recognition definitely does, especially if you train it while wearing your glasses." "On the note 7 it worked with glasses" What was that again about iGnorance? Pathetic lying numbskull...

Thanks . I don't take it as insult. Because you are very excited young man and emotions takes over. You may have few pubes poped out recently and I congratulate you. Now back to business . Couple of last comments on my link clearly speaks about S8 problem not N 7. If you can't make a difference between S and N I find it very difficult to continue with you. You also came up with face recognition thing that I never mentioned . I would suggest take a deep breath have a walk and try to destroy me :)

Haha u r just a butthurt hater. It works fore more people most of the time. You are cherry picking the failure issues and trying to show it as a major issue. Need a butthurt form??

Mine works every time except when the iris scanner is facing direct sunlight. Sometimes as soon as I swipe it opens. Extremely fast and works in all conditions for me.

Since you don't own the phone, and you dont even use the IRis scanner, why are you talkign about it. Until you actually use it everyday for yourself, you have no idea. I never really care about negative claims that something doesn't work, until I try it. What I can say based on using the Nite 7 and S8 Irsi scanner, is neither work 100% of the time. However it always works more times than not. On my Note 7, I can say that when I did use it which was rare, 8 out of 10 times it worked as expected. On the S8+, I set it up, to see if it worked any different or better than the Note 7. It appears to be quicker. The catch in making it work is how fast you can line it up to your eyes. Hwoever, I am a poor example, because I wear contacts. Even though it works with them on, it is quirky. Hwoiever when I take them off, the only times in honesty it didnt work, is because I wasnt holding the phone to my eyes at the proper distance. I have used the Iris Scanner in complete darkness just like I do on my Surface Pro 4. The Surface works better at 99% I'd say, but its just slower. Its best used in a well lighted area. But it does work in the dark. In fact it can be pitch black.

I appreciate your honesty and integrity. I already cleared up and took back a claim I made about low light iris performance. I can also add on top to what I said it's not convenient too because of two step unlocking implementation. First to activate phone then scan. Honestly large majority of the people end up using FPS but wait here lies the problem S8+ is way too far even for long hands. Eventually I look at the big picture based on which I ask myself : Is it deal breaker for me? Can I comprise? I have Pixel which already nagging me off due to the FPS placement on the back. The next phone I will buy will most likely have it on front. ..tgh I was going to get S8 I liked it but compromises were too big this time Lord knows.

I can confirm. With glasses, it only works 1 out of 10 time when there is light. Works better if I remove glasses if there is light.

I wear glasses. I can confirm, with glasses, it only works 1 out of 10 times or may be even less. If I remove glasses, it works pretty well but holding the phone to align is a bit awkward. (Sorry for duplicate, cant delete the comment, as I thought the previous one doesn't post)

Mine works great in the dark, works great while wearing my contacts, even works great while wearing my contacts and my polarized sunglasses. But it suck horribly direct sunlight, it is completely unusable then. But everywhere else it's pretty much perfect.

@nebula: It's better when you test things yourself before you repeat what other people claim. The iris scanner does even work better in the dark as there are no bright lights which can distract the infrared lights.

Funniest thing is Iris scanners work best in the dark. ANYWAY HUGE TIP TO ALL S8 USERS DON'T EVER EVER USE FACE SCANNER IT'S USELESS. IRIS IS MILLION TimeS BETTER.
