I haven't received my Galaxy S yet but everytime I use my friend's I think the screen is just too blueish. Mostly the white parts. And I also think a "square field" is visible all over the screen. Is this because the resolution is too low compared to the size?
The phone itself is great so I still want it, but I'm afraid the screen will make me disapointed, especially since I've read so much about the Super AMOLED is so great.
Are all Galaxy S' screens like this?
What is the "square field"? please explain better.
And let's start from clearing the point of resolution/size-
800X480 is more than enough to go up to 7". If anything, it might be the pentile matrix that the screen uses.
I guess it's these "squares" I see: http://www.engadget.com/photos/iphone-4-vs-samsung-galaxy-s-display-face-off/#3115591
You're probably right that it's more the pentile matrix I notice more than lack of resolution.
I cant understand why many reviews says this screen is very good when it's very noticable.
I've seen mentions of different Galaxy S phones having different colour temperatures, though mine seems fairly cool.
PenTile does, unfortunately, make text less sharp, and there is a bit of a screen-door effect (I think that's the term you're looking for). It's a tradeoff for having a Super AMOLED screen - excellent contrast and very bright, but not as good as a TFT for text. I've become accustomed to it though, despite my misgivings (but a non-PenTile SAMOLED really would be the best screen without question).

What's the good side with PenTile? And yes, I've searched for "screen-door effect" and it seems as if that is what I'm seeing.
Yes, Galaxy S display seems to have quite high colour temperature. You can sort of calibrate it using the calibration app that was developed for Nexus One a while ago and is now part of CM6, but you have to run Froyo, install it manually and lose video overlay, so it's not really usable right now. Nevertheless I've managed to calibrate my SGS to more or less 6500K using it.

What is the downside of losing video overlay?
Not being able to play back videos and shoot pictures and videos Or, to be precise - you can do all of that, but all you see is white screen

Oh. Well, guess I'm not going with that solution then
But since it can be done through software, does it mean that Samsung could make an update and fix this?
I had this on my old galaxy S and coming from the x10's tft it was painfully obvious the white colour had a blue/green tint to it. I then got it replaced and the tint was still there but not so obvious. Now after a while the white colour looks perfect white. I think my eyes have adjusted or something.

Ok, guess I'll have to wait until I get my before I know how bad it is.
My friend got a blueish Galaxy S I9000. Mine isnt that much!! Next to his looks like mine is Redish, but mine next to my Monitor looks blueish! I believe some Screens have more blue tint than others
Mine is very white. Put the phone on a white screen (using a screen torch app) and the screen looks whiter than a piece of white paper.
Hey all, keep us updated if there's any application that can change the color temperature without affecting the functionality.
I got the phone a few days ago and my friend's is defenitly more blueish than mine. I dont notice the screen-door effect anymore so I'm very very happy with it.

I´ve read something on a German Mobile Phone Review Site (don´t know the which one it was now) and they said, that this is normal, because of the AMOLED Tecnology. They said that the Colors will loose the intensity over the years and as blue is the most energetic Color in the spectrum it looses faster the intensity. That is why it looks now maybe a little bit diferent. After a while it should normalise, because it was planned by the manufactures.
Ok found the Site. Heres the translation:
Higher blue components of the display of the Galaxy S may have been deliberately created by Samsung with the idea that the blue OLEDs are aging much faster than green or red. After months of use should mitigate this effect and color balance to be balanced.

They could do that if they wanted to, yes. But don't expect them to do so, I don't think colour temperature is of any importance to them if it stays within usable range.

Got this tip a while ago on some other thread - you can start Video player, play some video, go to Settings and change the Colour tone to Warm. It stays changed even when you leave the player. It's not perfect, but it helps a bit.

Actually, YES! Your eye do adjust to the white that you are looking at.
You've been doing this all of your life and haven't noticed it. The light in the morning is a very different color than the light at noon. In the morning, it is likely very red if the weather is good, and very white at noon... yet everything looks normal to you... because your eyes adapt to the color.
Adjusting to your screen is the same way. But compare it side by side with another screen and one or the other is going to look "wrong", usually the one you haven't been staring at all day!

Congratulations, your brain has created a special filter, using a process called "adaption", by the human vision scientists, that blocks the screen-door effect. You didn't know it, but your brain created one years ago that blocked out the 'striped-lawn' effect caused by the columns of RGB subpixels on conventional color displays. That 'striped-lawn' effect was just as visible the first time you saw one, but that was likely many years ago.
Okay so this blue tint thing is somewhat strange, still no clear answers.
Some people are saying "this is normal for super amoleds." I have to disagree. If this was normal, then every single Super Amoled would have this blue tint. I've put my samsung galaxy s vibrant side by side next to the samsung galaxy s epic, fascinate, captivate and other vibrants. Some have a blue tint, and others don't. Others have nice rich whites, while some like mine have a blue tint.
Makes no sense, so I'm not buying the "all super amoleds have this blue tint" statement. They don't all have them!
I've used my phone for over 2 months now, and the blue tint is not fading at all. Something else people said. I don't plan to keep this phone for 10 years, waiting for the blue to fade, I want nice white now, not blue whites.
Anyone have any updates on this blue tint some galaxy s phones show?
I've had my N7 for a week and a half now, and there is only one flaw: I have a 1.5cm dark band down the right side of the screen. It's only really noticeable on white or solid pale colours, so for videos and games it's fine but it's a little distracting when reading black on white.
I have only the slightest amount of backlight bleeding round the edges, even under extreme conditions (ie. full brightness in dark room,) no dead pixels, no ghosting, no issue with washed out colour. So I'm just wondering if it's worth getting a return or just waiting to see if it evens out a bit.
I haven't found any mention of similar issues on the forum, so I'd like to ask how people are finding the uniformity of the display?
same problem
I have the same defect.
How did you resolve? Did you get a replacement?

I think I might have the same problem. But with mine it only shows after having the screen off for a while, and it slowly fades to normal after the screen warms up.
So far what I have done is have all dark themes so I dont see it anymore. Have tried to refit the cables inside and using pixel fixer apps, none had worked.

Anyone having the same issue as me? Cause it seems that My set that I just gotten today (Green color) has the usual yellow tint that is slightly visible, but not as serious as the z2. Can be seen when placed side by side the retail demos of z3 and z3c, it seemed like there may be different manufacturers for the display as well. It's not cool white anymore.

Yes there are different manufacturer, mine also has less white whites than another unit. But overall mine has better contrast so... As for the yellow screen it is not necessarily a bad calibration as displays whites are usually too blue in comparison to daylight "real white".

Ahhh I know right. The color actually looks decent, due to it being slightly yellow, but mine has slightly more yellow, nearing the z2 one. So I'm going to go down service center to check tomorrow.
Just got my note 4... upgrading from a galaxy s3.
I notice on the lower capacitive buttons there are visible lines in front of the lights, same for the top led indicator.
Normal?
Yes.

I'm guessing you got black right?
My last 3 phones have been white and i was planning on a black N4......but once i noticed the choppy look the lines made to the capacitive buttons on the display model, i went with white again. Same lines just not visible due to lighter coloring.
That is the design. It not defective it normal
BAD ASS NOTE 4
Yes I got the black.... it may not be defective but it's annoying!
Thanks for the quick reply!
I'm sending mine back today. Getting a replacement because of the PINK screen that occurs when the light hits the device. I'm getting the White one. Looked at a tmobile store And the black was the same as mine. And the whites WHITE was clearly different than mine. Mine seems brighter but it also has that tint and the my white looks sort of blue.
Sent from another Galaxy! Note the difference!
I got the black and I have the lines too. It's one of the few things I don't like about this phone, it just looks like a manufacturing defector something. It's not enough to make me get the white one though, I had a white iphone and that glaring white border every time I looked at it was too distracting.

I keep hearing this more and more and from my experience it rings true, many of the black notes seem to have purple tint and less overall brightness.....
It has good brightness..the black just has more brighter whites than the white note 4. why? I don't know overall brightness is the same.
Sent from another Galaxy! Note the difference!
The first black one i saw in store was not as bright as my note 3 and the whites were purple/bluish......almost passed on the note till i tried out a different display model a few days later, it then became apparent that there were some notes with the issue and some without....i went with white because of the issue the op is talking about....don't like the lines through capacitives...makes them look choppy
Ok. Is anyone facing screen issue on your P20 Pro? There seems to be a gradient colour shift which is very obvious in a dark room when the brightness is set to low. Plus it has a green hue to it. Have a look at the picture attached. Thank you.

Can't say I've noticed it, will take a look tonight.
Yikes!
I haven't noticed either but I'll also take a look tonight.
Either way i would say swap it out because that is nasty.

What software is used ? i want to try to see if i can reproduce it.
But from what i have tried with text on dark backgrounds my screen does not have that colour gradient shift.

This is Moon Reader+ and the brightness (which can be adjusted from the app itself) is set at 0 and -25.

Ok going by the screenshots is moon+ reader
I tried it for myself and with brightness turned down to zero on phone and in the app i can also see a very slight hue.
But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.
And since my and your screenshot are suffering from the same hue shift , it might even be a problem with the moon+ reader.....

Thank you very much for following up. It happens in the gallery too. I've tried it with different pictures that have solid colours such blue, red, green, grey, etc. Do you think the warranty covers intentionally? I bought the phone with full of excitement while I was in Singapore for a holiday. I love this phone so much but the screen is bothering me. Sigh!

I'm pretty sure its not covered , the screen works flawless under normal conditions even in the the dark. Only when i go to extreme's like setting negative brightness levels in software the problem really shows up.
I will never have this problem unless i actively go and look for it.
same for me. the vertical and horizontal lines are not really an issue for me, i though i can live with it: i had the same on my p9 plus but on the left, there is a 2cm zone on all the height really darker and it made it almost unreadable at night (lowest light), even with screen filter or not.
i returned my phone and now i must wait to order a new one... my provider tell me they will not have twilight anymore.
i'm very disapointed.
Amoled screens are always a lottery when it comes to uniformity. Sometimes you have luck other times not. There are good screens out there and this time around I got one of the better ones. I have seen others complain about screen issues so not all screens are good like with most phones that have Amoled. Below is mine at 0% brightness and the app you used.
Mine has the issue as well. I ll be getting my device replaced soon as it also has a slight gap between frame and back panel at top left edge
Same issue here. First P20 Pro had it from bottom to top (pinky purple at the bottom, yellowy green at the top), second one has it left to right, but more pronounced on the bottom of the screen.
Is it worth replacing it again? I'm not happy with paying a significant amount per month for this if the screen is bad on all of them.
I would like to check mine. What is the best way to check this?
Update: So i opened lcd test app on my p20 pro and here's how mine looked like in the dark.
I don't know if i did it right but tell me if i need todo anything more to check this propertly.
Oh ffs, my third one has it too. Significantly green in the top left running about half way down the phone.
I've now been to the store 3 times, it's a 96 mile round trip! Nearly 300 miles of fuel wasted on this rubbish.
I get "it's a chinese phone," but we're paying Samsung prices for it, these screen issues are just unacceptable!
Have p20 pro for 2 weeks now. Always thought it's some dark theme design before found this topic. Have top much brighter than bottom in low light conditions. Can't see in bright room or in dark room with brightness more than 50%. I wouldn't be worried if it wasn't so annoying while I watching YouTube before go to sleep. Half of the screen grey, another near to black.

99% oled screens has this issue. Some are less visible, some more. But every oled screen phone I held had this issue.
Now I have Note 9 and dark grays are uneven too.
