what you described sounds like what happens on my new crappy screen. Samsung make Amoled screen panels which are excellent quality and based on LED technology. the fake cheap copies and based on LCD technology which doesn't cope with shadows (goes pixelated and off colour) and has bad contrast range and an uneven hue to certain parts of the screen. I know because I'm stuck with one myself...
looking at the top of the panel where the word Samsung is, the black surround if you have black is actually a 3D textured effect. the copies are more dull flat grey than black.
if this is what you have the only thing you can really do to improve the quality is adjust the brightness levels until the visual artifacts are at their minimum. you won't have proper toughened gorilla glass if it's fake so you should easily be able to scratch an out of the way part of the screen to test it.

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...

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.

Anyone else experiencing this??? It looks weird almost like it's a lag or something but it's not. It's like a legit pinkish type tint when scrolling. Am I gonna have to return my device ALREADY?!?! I literally just bought it 4 hrs ago -___-
EDIT: OK so I'm informed this is called "smearing" and that's the perfect word to describe it. Only happens in the settings, looks like the words are lagging behind my scroll and catch up lol. Is there a work around for it or something? Even though there shouldn't have to be but that'd be nice i I didn't hafta go through the process again of getting a new phone a day after I got this lol.
If you mean in the settings, that's normal. That's screen smearing/ghosting. Explanation is in this video here http://youtu.be/C_APG3kLiYs around 13:30.
The pink tint issue is another thing.

Yes, it only appears in the settings that it "smears" as you call it, yeah actually smearing is a way better word to describe it, not a different tint. Is it on every S4 that this is happening, or is it a defect in only a small % of S4's? And is there a workaround for it?
Also, what is the "pink tint issue"?
Thanks!

It's the software. I've heard of the pink tint but haven't read up on it. I heard the smashing affect is cleared up on the new update we might get but that could just be talk.

Yes. Every S4. There is a work around. But it takes away from the screen by messing with the gamma. The pink tint issue is when part of your screen is darker than the other. Like my S4 is dark at the bottom and gets lighter as it goes up like a gradient. Like this picture http://i.imgur.com/9jhVEnr.jpg or this http://i.imgur.com/DhryGwg.png
It's more noticeable on grey screens.

The smearing will only happen in dark settings yes. It has to do with unused pixels. Like the video I posted before explains. If you don't have a pink gradient issue then you're all good. If it does I'd get it exchanged asap before you're stuck with it like me.

Hi @all
is it normal to have a perfectly white display when looking straight at it and to have a slight reddish veil while tilting it? And is it normal that Amoled Cinema and Amoled Photo Mode are a lot more reddish than adaptive mode?
I am on my third Galaxy S8 now. My first one had a perfect display, even when tilting it had the standard blueish color of the Amoled Displays. Had to send it back because of a hardware issue.
My second and third one have the above mentioned "problems".
How is it on your device? I'm already thinking of returning even this one... i want a perfect display for the price I am paying.
Thanks for your reply.

@Duskfall89 mine has that red veil issue as well but not enough to make me go nuts. I once had 1+1 and yellow band issue drove me nuts. Nevertheless, i think you can just set the red to the lowest on the RGB settings and it will go away. Im more worried about the battery haha

It's not an issue of being standard on oled displays. The blue tint is to produce a "vivid" look that catches the eye better.
Cinema and photo are suppose to have a warmer tint to match real life viewing. (because in real life, things have a warm tint) from the sun, and standard lighting.

So is it normal that cinema and photo mode are more "reddish" than standard adaptive mode? I never tried those modes on my old S7 so I don't have any comparison.
@Duskfall89 i know how you feel. i can also verify that mine has a red veil when switching from cinema/photo/adaptive. Regardless, i think i can live with it. After going through the forums, many s8s are plagued with this issue and i got mine on Monday mind you! Others have mentioned that they have swapped around 3-4 units with most experiencing similar redness. If you're not satisfied, there are also who have swapped till they got the least red display unit but that would also run the risk having other parts that come faulty.. alas, people are never satisfied. I once swapped 3 msoft surfaces.

Yes, it's a lottery I guess...
I think I will stick with it, it really doesn't bother me too much, it's more about the fact that i know how my first S8 looked.
Amazon won't replace it anymore because it's the third phone I'd send back and so they want to check their entire stock. They offered me a complete cashback if I return it but then I would be without a phone. I could give it back, take my cash and then buy another one (which is now much cheaper than the price I paid at launch) but I am tired of setting up phones now

Yessir. They use a warm base as opposed to a cool base. If you really want to learn more about it Google TV color calibration and it will go into detail about why they use a "cool" blue tint for floor and selling and how true natural colors are more "warm" reddish
Then I recommend calibrating your TV and after a day of adjusting, you'll never want to go back.
Also, blue filter in the Phone settings will add a warm tint at night to help your eyes
@Acoustichayes good info !!! i guess i wont be so worried! but i guess the only issues here is that my reddish areas are focused at the top of the display and is not uniform across.

I had the same case but cannot really consider it as an issue as sometimes, i cannot barely see it. It's just the way it is. Also, you might wanna check out wider color gamut. i think that we're just used to the "blueish" as it looks natural but samsung uses deep red this time.

Hi, what do you mean with "had" the same case? did you get rid of it?
I got used to it now and it really isn't an issue but I'd prefer the "blueish" tint as my first S8 had that. Sadly it had the home button bug so I returned it.

Ok then it's the same as mine I could be make it more white if I'd play around with the colors but even then, while tilting the reddish veil still remains. Less noticeable but it's still there. So I decided to leave it as it was out of the box. At leats my home button now seems to work properly :laugh::laugh:
I have these 2 very light yellow areas on my screen.
Here's the interesting part, they don't show up on screen shots. They also appear to be getting brighter.
A new screen is probably the only fix. But I'm curious of the cause. Any ideas?

If they are hot spots (bright white dots) then they are part of the screen and a new screen is the only issue.

The colour is because of a ****ty screen. @acejavelin mentioned in another thread that they are caused by compression for some reason. Don't know how that happens. Like @dzidexx said another screen is the only thing which can solve it. Or deal with it, I do not know how bad it is sorry

Defect rather looks like "Lights behind the closed door".
Do a black photo or jpg file. Look at it with different levels of brightness.
Sometimes it can be observed with other colours.

The last two pics are it exactly. Even though its a little annoying, I still love this phone!! Its the only issue I've had and I use it a lot. For everything. Between flashing, modding and every one of my boot animations has been made on this beast!
And thanks for all the input on this issue everyone.
And sorry to all those who suffer as I do with this affliction. Just kidding.

Hardware !! Read the thread and you'll see it has been made clear it is hardware.
I have the same issue. If I press on the bezel next to the yellow area with my fingers the colors go back to normal until I release. Could this be caused by the screws inside being too tight?
I would disassemble my phone and try to unscrew them a bit but since the back cover is glued I'd rather not unless I'm sure that's it.

Hi guys
I have a used V20 but the colors of the icons etc are quite dull compared to my wifes V20 and also the whites are more yellowish when compaing side by side. Which part of the phone affects/determines the LCD colors? Is it the digitizer itself or does it have to do with the mainboard producing the colors?
Thx!!

Yes i have it turned on. Screen colors are still quite poor compared to my other V20. Colors seem faded a bit.
Im thinking maybe its due to age or wear. But our phones arent THAT old.
