S8 Screen uniformity - Samsung Galaxy S8 Questions and Answers

Hi guys.
Have to tell you that on almost my previous Samsung S- models, I've always encountered issues with amoled screen brithness uniformity on white/grey background, really annoying for me. I could always clearly see a lighter and a darker portion of screen on light plain backgrounds.
Could you tell me please how' your S8 are? Is also this time a screen lottery?
Thank you.

You must have missed the red tint discussions. In those threads it's often mentioned that screens aren't uniform. Anyway, it's a lottery alright.

Display of Black colours

Hi guys.
Just a Quick question:
I compared the screen colours of my Z2 with my old Samsung Galaxy S2 using the app screen test.
There I noticed, that black on the Z2 isn't really black while on my S2 black is truly black.
Is that normal?

Its normal as far as i know Samsung phones use Super Amoled screen which has darker black while Sony use IPS screen technology has less darker black ,, dont worry its totally normal
It can't really be darker than the screen itself, because black is absence of light, which means the light sources are turned off when displaying black.
The color black will be as dark as the panel.
Well the panel is definitely much more black when it is turned off.. In the end the black white contrast on my S2 is much better
When I run the screen test app, when black is being displayed, the screen isn't off though

IPS is lighting even when display black, compared to AMOLED where every pixel has its own led diode so when AMOLED display black, its pixels eventually turn off. Thats why..
Different display technology, both have their adv. and disadv.
On amoled displays black pixels turn completely off, which is why it has so good contrast.
this is completely normal, because the superamoled panel have isolated pixels. the black in amoled panels is literally black, no light emitted, only the reflections from screen. in a complete dark room, the screen blackness would be the same as the room. LCD panels cant do that, the best ones can do something like 0.08cd/m2 of black levels, this mean that the black is actually greyish, while super amoled can do 0cd/m2 meaning infinite contrast. according to reviews xperia z1 compact have a black level of 0.44cd/m2, and while the z2 has a better screen, the black levels should be around the same
thx for the explanations.
Light emitted always needs battery consumption so I would assume, the amoled screen is especially with dark colours more battery saving, then the lcd screen, right?
Yes it is

Vertical banding on the display, unsure if I should replace the phone.

I've had the S5 for about two months and have been happy with everything except for one issue:
At lower brightness, and especially on greys, there are dim vertical lines that are evenly spaced out across the screen (like | | | |, all the way from top to bottom). Some backgrounds also exhibit a grainy-ish "linen" texture.
I've done some googling and it seems this was an issue with previous Galaxy phones and AMOLED displays in general (especially that linen texture), but I'm not sure if this latest generation of AMOLED displays is still supposed to be like this. I tried going in-store to compare with other S5s, but it's really impossible to tell with all the lights and they won't let me take a phone home to test.
Can anyone recommend what I should do next? I'm not sure if I'm being picky or if this is an issue.
I can't see the same issue on my display and this is my first AMOLED device. But if i look really closely I can see small black dots spaced out on the screen due to the matrix of the display
LG G2 has the same problem. Cheap ass manufactureres.

Pink tint in white background

Hi guys.
I'm a Note 4 user.
I love It, but using white background i find a little area in the low half screen not so white but white /pink.
Tilting the screen white is cold.
It's normally?
Erica Griffin in Note 4 Review spoke about this problem in her video.
Ps. Why "Reading Mode" is missing in Note 4?
Same here. I have seen a lot of N4 - an they all had a pinkish tint on white backgrounds. One more, one less.

So this is not a problem?
Of course this is a problem. But as I said before - this is the way nearly all the N4 screens I have seen look like. I fear you have to accept it.
Try changing screen mode
Adaptive or Cinema makes it bluer. But having half the screen colder like that isn't normal.

[QUESTION] How to solve yellow screen?

Hi guys
Several days ago I received my Nexus 6p. The phone is impressive but it suffer of yellow tones in the screen. I have searched and I have read that it can be solved through ElementalX Kernel (including to improve brightness). Have you tried it? Works it for solve these problems (yellow screen and Brightness)? Thank you very much
Someone?

If all the screen has a uniform tint on it you can solve it with custom color profiles and kernels. My 6P however has uneven yellow tint. The lower screen has yellow tint while the top is warmer and normal looking. This is very noticeable on white background. For this I don't know if it's even possible to be fixed without returning the phone. Some people claimed that the yellow tint is because of faulty glue or screen coating. Some even said it goes away after some weeks of use which I don't believe.

Uneven screen color temperature

Just got my Android Yoga Book. Fantastic piece of hardware. The best tablet I put my hands on in a while.
However, I do notice uneven color temperature on the screen: right side (where YogaBook logo is located) is slightly colder (looks more bluish), than the left side (which is hence warmer or yellowish). It's not huge, but I can definitely notice. It's most visible on the white background. I'm trying to figure out, if I can live with it...
How are your screens?
I am pretty picky, and almost on all recent devices (MSI laptop, Moto X smartphone) I had to go through a couple of RMA exchanges, until I was given a screen, that satisfied me... I saw such issues even on the most expensive iPads, but my girlfriend says I'm just crazy...
girls are always right, period....
My screen apears even in terms of color to me. However I am not too sensible - did you check with different ambient lighting?

Yeah, I can notice unevenness at any ambient conditions. I will try to exchange my tablet, as I've been trying to ignore this issue for several days, but it bugs me every time I look at the screen.
I can't see any variance in color temperature on my Yoga Book.
I have also noticed this on my Yoga Book. It is a very subtle issue and I have to focus on it to actually notice it.
Its on right side as OP said so probably a factory/construction issue.
mine is ok at the moment. Got mine from UAE.
