Is your Iris Scanner always blue? - Samsung Galaxy S8 Questions and Answers

Seems on the far right at the top of the phone, the Iris Scanner's blue light or whatever is always on. It's almost like a notification light that never turns off. Anyone else seeing this?

Thats just the color of the lens

Makes sense as it's an IR camera, reflective coating to reject most visible light.

Thanks. It's the one thing about the phone I do not like. Its quite reflective and distracting while looking at the screen.

I must admit I didn't notice this last night when inside, however when I used it this morning in daylight it is pretty blue. Quite annoying really but I suppose I will get used to it

i have been having the same issue with the light blue light. its not the lens or reflection either. most of the time its on and hurts my eyes if i look at it to long. that or maybe its just big brother watching 24/7. haha

oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.
I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.
This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

Eheh it's me that started that thread and i think that guy really did a great job trying to explain what's the problem... now i'm curious to know how many people notices this because till now it seemed that only me and that guy could see this "issue" so sometimes i'm still worried i have a faulty phone...it won't be a good thing since I'm from italy and getting a replacement phone wouldn't be very easy
My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

ok thanks, it's just reassuring to know that its not only my n1 experiencing this
Seen it slightly a few times. But never bothered me since I'm never in very low brightness that much.

[Q] track pad light

The track pad had a very dim red light in it when you wake the phone youll see it, its nothing like a notification in the center right side... Just questioning what it is and if we can get to it :/
once you see it youll always see it
I had no idea there was a light in there...ive noticed the red tint to it in some lights but assumed that it was something to do with the touch sensors

yeah when its completely dead it and you plug in the charger it has an extrealy dim red light in the center of the left side
but i thought it has a notification light that goes around the whole thing like the g2... maybe im wrong?
also has anyone noticed if your in the dark and light up the keypad light comes through the bottom right corner (right next the the G button) kinda like the paint faded... not a big deal just pissed i noticed it cus now i always see it lol just wondering if everyones is like this... btw sorry if i made you notice it lol

Yea the corner by genius button is just like yours.
I havent noticed a light on the trackpad tho. I even looked around for an app or something to activate it. No luck tho....
its not a light... its a dark red lens that covers the optical trackball... there is no (visible) light what so ever in there... you just held the phone at a odd angle in the right light...
go look at any other optical TB if you dont believe me...they all have a dark red hue (regardless of the battery status on the phone)
unplug phone from charger, pull battery and look closely, it'll still be red, and without power nothing could possibly be "lighting up"

i wasnt saying it was like a led its just a dim light thats behind it which looks red because of the cover on the trackpad... but seeing that made me question if there was a notification light down there like on the nexus one's trackball for instance
There is definitely a light on mine. I see it every time I wake the screen.

Noticed the dim red light too

Mine has it too when I wake the phone up

i though it may just be light from the menu button peeping through but itll do it when the keys arnt lite up :/ hopefully its an led and we can get it brighter for notifications cus that'd be sick (thats one thing i would of liked how the g2 has it going around the pad)
Afaik the only light down there is infrared... if you can see it you got some sick ass eyes, or the lens on the trackpad is somehow reflecting the light or something... but like I said turn the phone off and pull the batt and I still see a faint red hue in the trackpad...

There is definitely a light in there that illuminates for a brief moment towards the left hand side of the button when you wake up the phone with the track pad. It is no reflection of the infrared, it's a light. Do it in a completely dark room and it will be obvious.
I don't have this at all. If it's a light, it would certainly be more obvious, no? How could a light be so dim?
I noticed this last night when I was cleaning my phone. It is definitely a dim red light.

lol u got some sick ass eyes
Yeah definitely seeing it now too once it has been pointed out. It's more in the left center of my track pad.
I think it's just the trackpad sensor light, similar to the laser light under your optical mouse.
I don't see it doing anything but registering where your finger moves.

[Q] Screen Light Leak Problem?

Has anyone been having a issue with there screen where light leaks out of the corners of the screen? Mainly on blacks and other dark colors? Is this normal or did I get a defective screen?
Mine has a tiny bit of light on the top right (about 1/4 from the right, where one of yours is). It's extremely hard to see, and only shows itself when the screen's pitch black and the room lights are off. So not a problem for me at least

Bottom half of alarm app screen not pure black?

In all other cases where pure black is present, the color really is black thanks to the amoled screen. However, I noticed that in the stock alarm app, if you look at the bottom half below the list of alarms, the black that's there is like a hazy LCD-like black. I noticed this when I was half asleep at night setting my alarm in a dark room. Most noticeable when you look at the screen with the lights shut off in the room. Contrast that to the deep blacks found when pulling down the notification shade. Can anyone else confirm? Thanks.

I was thinking that maybe since it's totally dark in your room, you're seeing glare/reflection from the menu and back button LED's... but then I guess they wouldn't be lit unless you have them set to always on. I just watched Insidious 2 so I am not going to try the dark room test :3 maybe someone else will lol

Yea it's pretty obvious once you look at it. If you compare something you know is real black (like the bottom half of the notification shade, assuming you don't have much notifications at the time) to the empty bottom part of the alarm app (LCD-like hazy "black"). I'm pretty sure it's just the alarm app doing something funky by design, but just want to make sure heh. Pretty sure I have an authentic amoled panel anyway as I do see deep blacks in other situations.

I couldn't resist giving you some peace of mind so I just tried it out in the bathroom. The alarm screen does have a weird black'blue hue thing going on. Especially when you compare it to the notification pull down.

Lol thanks... yea looks like uneven LCD-ish off-black.

Not really a question... Just an observation

Does anyone else glance at the phone and think the front facing camera is a dim blue led?
Nothing I can do about this, but I just wanted to know if this has been bothering anyone else.
That and with the always on screen, I keep thinking I'm the worlds most popular guy today but really no one is texting me... haha
I think it's just going to take some getting used to...
I think it might be the iris sensor. It's an IR sensor so has visible light filter that I've heard reflects blue and can look like a blue LED.
