Super Amoled Screen?

Hey guys quick question
Me and my girlfriend both have the SGS but I noticed today that he screen has a weird yellow colour when compared to mine.
Like my blacks are black, where hers just seem off from mine even at low, medium and full brightness, power saving lcd thing off on both.
We are both running JPU.
Is her screen dying or is it faulty? if so should i contact samsung for a replacement model?
Thanks

Hi
I have an issue where my screen is much darker than those of friends of mine, both with brightness set to full on all phones or with auto brightness on. I didn't notice it at first but now that I did it bugs me like hell. Maybe its related.
Depending on country and service center it shouldn't be too much of an issue to get a replacement screen / device. It goes without saying you have to roll back from JPU to the original froyo for device.

Running any custom kernel with colour fixes etc? I think some roms/kernels tweaked the settings

I think its possibly some variance in the manufacturing process. Mine has a blueish tint which i find quite annoying, but only appears when looking at it from the left hand side

Thanks for the responses guys, we are both running stock JPU roms but ive contacted samsung and they said they will have a look at it :/

[Q] blue artefacts / subpixels all over the screen

Hey!
I bought my galaxy 6 months ago. Not long after I noticed a minor issue with my AMOLED display. I could see blue "artefacts" in some bright areas of the screen from time to time. Nothing serious, just blue dots and stripes, subpixels. I even posted a picture of it on reddit (second attachment) more out of curiosity than anything but was later convinced it was probably a software issue. I did have some suspicions something might be wrong with my phone but it actually happened so rarely and the issue was so minor that I just got used to it because it didn't bother me that much.
I recently flashed dark core 2.2 along with rc6 and it got *significantly* worse. I could see blue subpixels all over the screen wherever there's bright white, generally on the lowest brightness setting. Now, I believed that the hardware got worse and it's time to ask for a replacement. So before doing so I obviously had to flash stock firmware and guess what - it all disappeared. So I flashed just the dark core again to go back to rc6 - and it was back again.
The thing is, I really love this ROM and I love the voodoo improvements that come with it. I don't think I can live without them any more. On the other hand, it might be difficult to convince people from samsung that there's actually something wrong with my phone - since it happens so rarely on stock ROM. And I think that this display defect is intensified by the screen improvements from voodoo/dark core.
My only idea is to somehow make it show up on stock ROM and send it to them just then. But is this even possible without rooting my phone? Does anyone has an idea why would these blue subpixels show up in white areas? Is it something they check with specialized equipment or do they boot the phone first to see what's wrong?
Anyway, guys if you could point me in the right direction or had any better ideas... Seriously, It would be helpful even if you said that I should just return my phone and hope for the best. I'm a student and I can't really afford to be charged for returning - what they think is - an operational phone
I attached two pictures
1. a picture of how my screen behaves after flashing the latest dark kernel
2. a picture of how my screen sometimes behave on stock kernels
I'd appreciate any help or advice

SAMOLED Burn in !

Hello XDA users !!!
Just noticed a thin long black line (vaguely seen) running from top to bottom of my screen on total black background i.e Grey (as it turns off all pixels and making the image more brighter on a black background but it's grey & can be noticed on a terminal with green on black option) and similar spots on my SAMOLED screen but there's no problem with the pixels all of em are 100% healthy.The images are clear,vibrant & bright but still this flaw/disadvantage is bugging me..!
And we all know that SAMOLED and SAMOLED Plus displays from samsung are extraordinary & superior over the AMOLED's, LCD's , HTC's RGB 720P AMOLED(Rezound as explained in Engadget's review) as Super AMOLED advantages are brighter screens, less sunlight reflection and reduced power consumption (Source: http://en.wikipedia.org/wiki/Super_AMOLED) but after this experience and some googling i had just discovered that sooner or later maybe all the SAMOLED or any type of AMOLED display users are goin to face this issue/burn-in and even the display will change like this .
but that's an intermediate stage of burn in .
Hope this info was helpful and there is no fix for this unless you get your screen replaced when this chaos x( happens to your phone...
Please report if any one's noticed the same.
Correct me if i was wrong ...!

C'mon no response ..?

I got notification bar burn after the first couple months but to my relief it hasn't got any worse in 18 months... Yay!
**Simply Honey 5.1 JVR rom & Talon kernel @ 1.3ghz**

Hi, I havent noticed any burn-in´s, but I´ve noticed those lines coming from top to bottom. For me it is the most noticeable on white background. I thought that the framerate is lowering down. Also it can be caused by CM7, will try in couple days to reflash back to SammyRom to see if it happens too.

Thankyou guys for your response ...!
and R34L2Pac please post your results after flashing sammy's rom.!

I doubt that's a burn in unless if you have a background with a line running from top to bottom. Burn in looks like artifacts that appears often on your screen, such as the digits for the clock on the status bar.

i run a BLACK theme, and even so i still got the status bar and its icon burned in on my Nexus S
good thing is, it's not noticeable unless you put a full white or full grey background on the screen
it's very easy to check with screen test

Yep, you are correct. Indeed i did mention that all pixels of my display are working properly & that weird problem made me to analyze, post a thread in here that could help many SAMOLED users to seek out any issues before hand with their precious devices

First of all, AllGamer (Moderator ) thank you for your response .
So, all these point out that our SAMOLED's are at a very high risk and even though you had a black theme your Nexus S but still it getting burn in.....
that's very sad .
by the way that app can't be tested on ICS .

Does anyone have weird vertical and horizontal lines on the screen?

I just noted (pardon the pun) that there are lines vertical ans horizontal lines when displaying white. This is my second phone. I went back to cpw and changed this one has similar horizontal lines. Its very very very faint, but I can see it. Im not sure why, it is because of the AMOLED screen, how it works?
Very annoyed. what can i do? every phone CPW has cant be faulty?

I've only had mine a day but cant see any lines like you've mentioned... maybe a bad batch they got in? Maybe something to do with the S-pen's digitizer screen, i assume that will have some form of grid to it

AMOLED seems to have weaknesses at low brightness levels.
Some have seen very faint lines .
Also on minimum brightness some reported a faint changing of the hue of the display.
The screen is also very bright (whites) on min brightness.
If you display a greyscale step pattern black is absolute black but
others that should be near black are too bright.
http://www.execulink.com/~impact/docs/utils/StepGray16G.jpg
I think its just the AMOLED tech but check the display thread too.
In normal use the screen is amazing,
all technologies seem to have good and weak points if you look for them.

You are not the only one with this problem. I'm on my third galaxy note now... The first one had dead pixels and the right side was darker than the left side. The second one had much more dark horizontal and vertical lines and smudges. The third one at first had very faint lines and smudges, but it is becoming more visible now. There are several threads about this issue on this forum.. My guess is that these problems are pretty widespread (more or less visible on some gnotes) and that there were some bad batches or that the Amoled technology is the problem. Would love to hear the reason to these issues from Samsung.

No lines on mine. White is white and everything shows up excellent.

If you disable the automatic light control and just snap the backlight up from 0% to anything above, you will not see any grayish things in video on the Note. I don't have this problem, but I've heard that some people have had to do this to solve this issue.
I don't have any bandings or strange lines anywhere on the screen. It looks as good as my Galaxy S II and Galaxy Tab. I haven't seen anything out of the ordinary (considering the limitations of the AMOLED screen).
There have been concerns about the lines on the white though. I don't have any of those on mine, but it seems some screens show up this fault. I don't know how to solve this issue and would recommend returning it as soon as possible.
Using the recommended gray test on the Note didn't show up anything but a solid grey screen on mine, although I've heard much people have dark spots all over. It might be something about where the phone was manufactured, or when.
My Note have never had anything wrong with the screen or anything else. The only problem I've ever had is applications that use 16 bit color instead of the Notes 32 bit. This will make color look strange at times, but it's totally normal.
Note that this isn't something wrong with the hardware, it's merely a software problem that will be solved as soon as ICS is released.

Lines/spots are due to ****ty quality control, this is just a matter of luck.

I have yet to see ANYTHING with more then 65k colors, even in the browser.
All i see is some VERY clever dithering very hard to see due to the high resolution.
Coming from the HD2, I'm really disappointed, nothing gained in 3 years (well, more pixels, so harder to see the flaws).
I took 3 picture with a green gradient:
1) 1280width, so basicly 1280 levels of green, but 24bit only shows 255.
2) 255width, so basicly 255 levels of green, 24bit.
3) 64 width, so basicly 64 levels of green, 16bit.
They all look the same to me, in browser and in gallery. I see dither in each of them. This tell me the whole screen is 16/18 bit only.
Maybe the PenTile is playing tricks with me...
Or the grainy screen lets me think its dithered...

i am facing a similar problem..whenever i apply some photo having a lot of black in it as my lock screen image..there seems to be some horizontal gray lines in it..but when i look in the gallery the black is pure black (no horizontal gray lines at all)...is there any problem in the software only ? or is it something regarding the screen?

[Q] Random Dimming and Heavy Greenish Tint Issues?

Hello all. So I LOVE my Samsung Focus S that I purchased shortly after Thanksgiving Day...all except for one problem. My phone seems to dim permanently out of no where and nothing I do will correct it back to it's normal brightness except for restarting the phone. Automatic Brightness is off and the "Auto Display Intensity" in the Extra Settings category is off. Now I don't know if this is something that specific to Windows Phone or Samsung Focus S particularly? I'm going to take a guess and say it's on the Samsung Focus S that exhibits this behavior. I also can't figure out if it's a hardware failure or a software failure. I'm beginning to think it's a specific update that is used to update your "Extra Settings". I don't know at this point. I just want to know if others have this problem.
The 2nd issue is not so much a problem now but a concern. My first Focus S had a VERY HEAVY greenish tint to it that was immediately noticeable at the lightest of viewing angles. To give you an example of how bad it was, my buddy was looking at a picture of oranges he took with his iPhone4, I thought they were lemons from the side. I went to an ATT store near me and noticed the Galaxy S II exhibited this behavior as well but the Focus S on display did not. I quickly concluded it was a defective screen as it was REALLY noticeable. My buddy gave me a call and told me he was at an ATT store across town and noticed it on another Galaxy S II as well. I made the employee take out two brand new Focus S' and chose the best looking one. They both looked identical, although the one on display had an edge over all of them. Thing is, ALL of the ones I've seen have a very slight green/blue tint to them. Is this normal with Super AMOLED Plus? Is this the Gorilla Glass Coating? I love the colors and contrast on this phone but to be honest the brightness and viewing angle leave something to be desired, more-so the viewing angle. Sorry for the long post!

I just looked at some pictures of oranges to test this. They look nice and orange do me. at an angle the entire screen starts to lose its pop. But I would not call it green more so just dimmer. Can't complain with the blacks...if only more sites background was black lol.

Would you mind doing me a favor and looking at different viewing angles on a predominantly white screen? Every phone loses it's composure a bit as the viewing angle is more and more off but I've never seen them turn a different hue. Dim a bit like you said? Yes. I looked online to see if anyone else notices this bluish/greenish tint and many do but more notice it on the AMOLED screen though a few did complain about the Super AMOLED Plus. Thank you!

interresting
Ive been running the focus s since it came out and never noticed this "tint" issue...till today. a simple image of pure white, when viewed from above is fine, but as you change the view angle so does the white begin fade into the bluish haze.
now youre all probably going to hate me but i have a titan too. when i pull the exact same image, it does not fade into blue haze. my suspicion is one of two thoughts: a) the super amoled screen samsung uses has this side effect. b) the glass samsung uses creates this effect.
personally its not a deal breaker for me as i really enjoy the clarity of images and color the samgsung has to offer. that said, the titans inability to go true black are more noticable than a slightly bluish white. but thats purely personal prefence.
FWIW, ive tested red, green, and blue matching images. the only difference i see between the two is a decreased viewing angle on the thc in all aspects. screen display differences is the likely cause.

I can see the blue/green from those angles on white screens
kinda ugly actually
still a few days left to return and get the titan....

It's good to see you have a Titan. The Titan is a pretty nice phone. Viewing angles seem quite good and the whites are SUPER bright. It's just the colors and blacks that suffer. Nice to know you can compare them though.

Hey Alright, I'm not crazy. Heh. I'm going to run to a couple of more ATT stores and see what their display units look like. My buddy just got a GSII and he says he doesn't see it, so I'm going to investigate it as well.
BTW, I spoke to someone at Samsung online and he seemed to think it was "normal" and was caused by a Super AMOLED Plus characteristic. Unfortunately I didn't believe a lick he was telling me.
I'm off to find the perfect display! Wish me luck.

i went back to the store
they want to charge me $35 to restock what I have ^^ - and cant seemed to be talked out of it....
the display Focus S had the same exact issues
as does the GSII/SkyRocket from what I could tell
the Titan's whites make the Focus S whites looks blue - but the Focus S blacks look the Titans blacks look grey
and the color palettes are so radically different - for themes the green on the Titan looks like the lime on the Focus S, and the Titan has nothing that can compare to the green on the Focus S - its ridiculous the difference in the saturation and vividness - I can see what people say about the Titan producing more realistic images - but at the end of the day for most things the Focus S is just better looking, who cares if its accurate?
i imagine using the Titan for a while you would get used to it, but side by side it looks paltry in comparison
to be honest the iPhone display looked pretty good! - just too damned small after using a 4"+ sized display - I could never use something that small after using what I have

So I went to ABT Electronics today and looked at their Focus S. It's funny, all of these places, including the Apple store choose the most PERFECT displays they can find in their inventory to show to the public, when in reality your results can vary greatly. For example, the Focus S at ABT had a whiter/bluer screen than mine in terms of whites. It wasn't a huge difference but it was noticeable. Now I want a new whiter screen. My screen seemed buttery compared to the one I saw. We'll see how successful I am. I know I may sound picky but if I'm going to keep this phone for the next 2 years, I want it to look the way I want it.
I also checked out others with the same 4.3" Super AMOLED Plus and I didn't really see much of a green tint to them. In fact one looked yellowish directly and turned whitish on the side. Weird.

OLEd is still a newer technology, compared to LCD - guess there are still some kinks to work out

Yeah, a problem with AMOLED is a slight bluish hint but I don't believe the screen is a PenTile one.
The dimming has been a bit aggressive, I just usually cover the proximity sensor with my hand and let it work again.
Has anyone noticed a flicker (then on) when you unlock the Focus S screen? Sometimes the screen instantly brings up the lock screen sometimes a second after the flicker.

Alright guys. Back to one of the original topics of the Focus S randomly dimming? I think I figured it out. My phone is over heating and the phone is dimming to try and cool it down. No error messages of overheating or anything. I noticed it today when I was playing games on my phone while charging. My phone was pretty warm. Now up until this point, my phone had not dimmed randomly for a week or so, but this morning? BOOM. Dimmed on me. So it hit me. Screen Dimming + Warm Phone = Overheating. I put the phone down on the cold floor to cool down for 10 minutes. Turn the screen back on and guess what? Original Brightness is back.
Either I exchange my phone again or return it all together. I'm in a bind because I can't get the HTC Titan for the same price I got the Focus S for (Free with No Activation).

I have not noticed this at all.

i am in the same boat
almost potentially worthwhile holding out for a Nokia set (perhaps the 900/850)
i actually think I will keep the Focus S to be honest with you
in a year or a year and a half, call up Att and see what they will work for me if I really want to - I have heard lots of success stories about calling them up and getting very discounted phones deals
after revisiting the store - the titan screen looks like **** (IMO except for the whites) compared to the Focus S - and its just too damned big - the Focus S IMO is the perfect size
and all the Android GUI overlays suck ass - so no way I get a droid - and I will certainly not pay $100 for a year old iPhone.

**this fixed mine** random dimming and tinting
Don't throw anything because I just skimmed over the thread before I am responding. I have the Focus S and had that problem. I corrected it by going to "settings>extra settings" and turning off the "Auto Display Intensity" to make it stop adjusting. Unfortunately, that setting defaults to "On" every time the device is restarted. So you have to remember to turn it off. Maybe everybody thought of this, already, and your device does this, anyway, but mine is perfect with this setting off. So, I hope this helps!

I had to use the option in the "Brightness" page under Settings. The option on the Extra Settings page applies only when it is set to a white background.
Hopefully a future update will address this and improve the auto dimming. For now, though, it's set to bright all the time.

U only need to press the power button to let the phone go to sleep, then press power button again and almost immediately the custom brightness u set will be back.

Well the dimming issue hasn't happened to me in quite a while now. I decided to keep the phone. The fact that the display wasn't perfect wasn't enough to make me want to return the phone, especially since I got it for free with no activation fee on a 2 year contract. In the meanwhile, I'm just enjoying it. Funny though, Now that I've got a 4.3" screen, I want MORE. Bring on the 4.7"!

Having had 3 Samsung Amoled phones (Galaxy S2, Skyrocket, Focus S) and a SAMOLED (Galaxy Note) I will say that Samsung doesn't display true whites, it's always blueish. As far as the dimming, Go to "Settings" > Exta Settings > Use Auto Display (Turn it off, however; it seems to enable itself after changing the theme from light to dark or vice versa, as well as after a reboot.)

I believe all the phones you had, had a SAMOLED + display no? Also, I checked to see if changing the theme from light to dark turns the Auto Display feature back on and for me it does not. As for my dimming issue, it only seems to happen when the phone is plugged in and the battery is a bit warm.
Overall, I like this phone but I also don't. The display is quite delicious really. I've had it on half brightness for a few days now just to see how it looks to me and today I finally put it back to full brightness and the colors really are gorgeous. It's not perfect but I've learned to look past it I guess. Thank you for the reply.
