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?
Check out how bad the backlight bleeding is on my brand new G2x.. it's terrible. boot screen, images, video's, games. all show it. This app called DRAW! gives you a blank canvas to draw on, look at the difference.
MyTouch4G on left, G2x on the right, see how bad my bleeding is. I think a need a replacement for sure.
Mine doesnt have any leakage at all
I agree you need a replacement
Mine did. I sent it back. Not because of the light leackage though, I didn't notice it unless the screen was blank
I sent it back because of the re-boot issues. My new 2x is waiting at home for me today
Oh damn... sad for you ;(
I don't have any bleeding at all on my O2x, and i would replace it if i had that much bleeding.
But maybe you should hang on for a little wile until that phone is in stock where you bought it, so you don't have to be left without a phone for a week or so :]
bought online at tmo.com, I'm going to return it and just go buy in store so It will be faster in case I have issues again.

That doesn't look good we have here two O2X which great screen and colors no leakage...
However one with an auto reboot but thats another story.
Just go for a replacement .
Mine looks the same but i don't care much about it. Had 1 reboot in 1 month so no reason too change it for me.
That's mine (max brightness). I'm heavily struggling whether i should return it or not. I mean that's a lot of leackage but under normal conditions you don't recognize it when you don't know it's there. The only situation when you can see it quite good is in the dark when really the background on that spots is/should be pure black.
That's major leakage. I have just a tiny bit on the very top right corner. Not enough for me to return the phone. You should return it. Coming from a super Amoled screen phone, I can now respect the screen on my former Samsung Galaxy S. It also uses no power for the black colors on the screen.
The top corners of mine is bleeding. Not that bad though!
yeah I had this problem too and returned it with a pixel broken too. the guy from the store only gave the money back because of the pixel because he said that is normal. some have more some less. well... I think we discovered why this phone is "cheap" compared to other phones. build quality
The top right corner of mine o2x is bleeding, but I don't really care.
I bought a new G2X off Craigslist. Just noticed some bleeding as well on boot up. Will T-Mobile give me any issues as far as getting a replacement in store since I bought it off someone on Craigslist?
i can't believe how much lucky i am...
i have an italian optimus dual...
and it's PERFECT
no bleeding(i didn't know before your post, and i tried it quickly... perfect lines)
no reboots etc...

What app can I use to make the screen black like that to test for bleeding?

Hi there,
The Galaxy Note is my first phone with a LED screen, I had a Desire HD before.
Since I got my Galaxy Note, the screen seems a bit yellowish to me.
When you tilt it a little bit to the side, you see the while colors becomes more white, but when you tilt it back, so the screen is right in front of you, then the white colors looks a bit yellowish again.
Is this normal for a LED screen?
I don't like the yellowish tint at all, but for the rest the screen looks amazing.
Thanks for your answers
Hmm I don't really notice any sort of yellow tint on my screen but then again I'm not the most color observant person . What you can try is go int settings==>display==>screen mode and change it from standard to dynamic or movie. I have it on dynamic and love it.

Yea I already tried dynamic mode, it makes the yellowish tint a little less, but it's still there.
You can notice it by yourself by tilting the phone.
Just put something on your screen that has a white color, and watch the screen from the side, it looks much nicer then.
Ohyea, by the way.
You can also notice the yellowish very good if you put the screen mode on movie
Just got my Galaxy Note N7000 today and noticed the same issue on mine. Tilting the screen slightly makes the whites look pure white while in its normal position the screen looks kinda yellow. I am not being able to understand if this is a faulty set or not
SAMOLED screens are supposed to have superior viewing angles, it is believed that the Oleophobic coating is causing the green/blue/yellow tinting that you see when the phone is tilted ( well in your case its a direct view ) my first screen had absolutely no color shift even at the most extreme angles, the new one I have now has a blue tint unless directly viewed.
The norm is supposed to have great viewing angles and only shift in really extreme and non usable angles.

Well, you don't have to be upset like that.
What I'm trying to say is that if you tilt the phone, it has great colors.
But when you look straight onto the screen, you see a yellowish screen.
Your conclusion is that the viewing angle are very good, and only shift in really extreme and non usable angles.
Looking straight onto the screen should not be a non usable angle.
And Im not the only one who's saying it, but when you tilt the phone, the colors looks much nicer.
Im not upset, I just found it amusing why it was not understood right off the bat.
Have your screen/phone replaced, thats clearly a quality control issue.

Still there are also some people that say it is normal.

He does have a point normally a screen comes in warm,cool and neutral depending on the factory calibration. These things can be normal as long as the user accepts them to be.

No problem, Keep us posted on whatever you decide.
I've had four blue Galaxy Notes and one white and they all exhibit varying degrees of tint with some less noticeable than others. Some have a more warmish yellow tint while others are cooler with more of a blue tint. It was the same way on the Galaxy S2. The best you can hope for in getting a replacement is one that has a tint that's less noticeable or if you prefer a cooler tint to the warmer tint.

Im very picky so first I notice a tiny chip in the surrounding metal and I can feel it by hand, but I thought oh well this is ok if the screen is perfect. but then when I turned the brightness to max, I noticed light bleed at the upper corner. It's also noticeable at 50%. RMA asap.. shame I just got it today, the replacement could take up to 3-5 weeks. Actually I ordered this for my bro who is oversea so I need to get the replacement before the last week of january for my uncle to bring it oversea to him, and this makes me worried if it takes till february. I don't wanna send a defected one to my bro and he's really looking forward to this.

This is the extent of my light bleed (pic below).
I've decided to keep it regardless; I don't invest much time looking at a blank screen when using my phone but if your brother does, godspeed and good luck.

Turn any LCD to full brightness and you get it, the only reason you don't see it from the media is they all have auto brightness on which solely exists to hide this IMO..
If it bothers you then use OLED.

Wao... actually mine is better than this (only 1 at the top right corner). But consider this is a phone ..light bleed is not acceptable whatsoever. On a tablet it might be ok. I can keep this N4 till I het the replacement. Hopefully the replacement will be better.

Auto brightness exists to save battery and increase brightness only when necessary, not hide light bleed

This phone is easy better, and I don't want to RMA it and chance getting one with a big problem. But my Nexus 7 uses an LCD a well, and there is absolutely no light bleed. My HTC ReZound had no light bleed, and neither did my LG Spectrum... both of which use 720p LCD panels, though slightly smaller ones. So, I'm a little frustrated.

any amoled cannot have light bleeding because the technology works differently.
LCD screens have a light behind a liquid display the display cannot emit light and requires an alternative light source to be behind it to shine through so think of it as a sandwich (backlight) / LCD / (glass)
ideally there should be material that prevents most of the light from escaping around the LCD itself however its not a 100% seal hence you get light on the edges; small devices like phones its more noticeable cause the light does not need to travel as far making the issue seem worse. generally this is a normal part of LCD technology however if it is EXTREME you should RMA some light bleeding is normal extreme light bleed is not.
AMOLED Does not have a back light so there is no external light source that can leak out around the screen itself instead the individual pixels emit the light hence AMOLED will never have light bleeding.
so if you have a little light bleed dont RMA you might get something worse and yours is most likely fine; your just complaining about a normal and acceptable flaw in LCD tech.
I've owned 3 different n4's and they all had light bleed. Noticed all had them in the right top corner, with one unit having more bleed at the bottom left. Don't rma it unless it's pretty bad
I bought htc one of phones4u and i notice when watching videos or something with a dark background, light bleeds from the home button on to the screen. The light bleed comes from the bottom right hand corner of screen, looks like there is missing a bit of seal from the screen so the light comes through, so i arranged for an exchange as i wanted it perfect and it was annoying, anyway just received my second handset and guess what still the same problem, It is not the same phone if any of you guys thinking this!! As the problem with this new phone is the light is bit more on the side and worse. So two phones both with the same problem.
Have any of you guys had this problem?? as i have scanned the internet and i cannot see anything about this issue. Surely i can't be the only one!!
I will be sending this back for a third time if it happens again will probably be getting the s4.
I have not had this problem nor heard anyone else with it. Can you get a picture?

I just tried this. I found I could see a tiny bit of leakage from the back button. But only if I went into the room with no windows, all lights off, and gave my eyes about 20 seconds to adjust....then I could "just" see it. I would never ever have noticed this in normal usage and I imagine some will not be able to see it on my phone at all.
The time i finish work it is pretty dark, so this is why i notice it. Mine is def worse than yours you can clearly see it best way to do it is to be in a dark room and put brightness right down on htc one, i will try and take a photo later for you guys to see.

Was really surprised to see this topic. My HTC One has easily been the most flawless screen I've ever owned. I've had some light bleeding, even if barely noticeable to anyone who doesn't have severe OCD, on almost every LED-backlist display I've used...until this phone. Even my new Nexus 10, which I settled on after many exchanges, has minor light bleeding.
Just checked my phone, don't have this issue. If possible, I'd contact the seller you purchased it from or get in contact from HTC to check out the warranty.
I came across the same issue. Anybody knows what's the cause of the issue? and how to repair it!
i'd appreciate it!
