Hi all,
Got the Galaxy S for a month, pretty happy with it. Yesterday, the brightness suddenly gone up. The worst part is the display lost the gradient scaling and it is replaced by colour bands!
Apps like the stock video player for example. Before the video is played, you can see the grey control bar at the bottom covers by a lot of colour bands. The colour of the movie is all washed out as if you were playing it in 8 bit colour mode. Where the same avi played okay before, crystal clear and colour was rich.
Same thing with the charging screen while the phone is off. You can see the colour bands on the grey area of the shadow of the green battery. Just wondering if anyone has the same problem?
Cheers!
Factory reset :d
Tried all that full factory wipe, data reset, flash to different rom. Nothing works
Then your device's probably faulty. replace it.
Pretty certain it is. I took a screenshot of the video player and it looks fine but on the screen, you can still see those colour bands meters away.
I guess this indicates the LCD is faulty.

The galaxy s has no LCD its LED
Ive noticed when you slide down that tray from the top, when closing it mine has MANY TIMES switched to full brightness. But simply tapping the brightness button on the multi widget thingy makes it go back to how I want.

Thats because you can adjust the brightness by sliding your finger accross the notification bar.... doesnt work if you have auto brightness ticked...

Hi I have the exact same problem! But I didn't notice it before now wen I saw this thread. But all the colours are just fine when I play a vid, it's just the grey controlbar that is by many stripes of different colours, looks like 8bit colour. But when the vid starts playing its just fine, because it gets transparent. Should I get this phone changed, have just had it a couple of weeks.

Hi Radat,
I posted more info in the other forum including some screenshots. http://forums.whirlpool.net.au/forum-replies.cfm?t=1520586
Hope yours okay. I am going to call Samsung tomorrow.
romhunter,
yup, saw the screenshots, looks like quantization problem i.e. that colours are using fewer bits than normal. For example, RGB screen might use 24 bits per pixel, 8 bits per r/g/b colour, the screenshots seem to suggest only 5 or 6 bits per colour.
Hopefully this is just a software glitch, though you said you already tried factory reset / wipe, could it be a loose cable wire somewhere or maybe a problem with the screen to mainboard connector?

awesome. theres so many little shortcuts like this ive yet to learn. thanks
On my sgs, there is a green colour attached to to the grey colours, I can see it really good when using Screen test app on the gray scale screen, all grey is sort of green!

Just got a brand new device. Used it for about an hour, then the exact same thing happened - out of the blue.
Any possible home-front solutions? Having to take it to be serviced is a PITA for me ATM.
Mine definitely seems to have banding in the video player control pane before the video playback starts. Can someone please post a screenshot of how it should be? I haven't seen the banding issue anywhere else except the battery charging indicator when charging the phone when it's turned off. And as far as I remember they were always like that.
So can someone please post a screenshot of how it should be for me to compare.
I have the same problem appeared after upgrading to Froyo. Brightness increased (even it is high in the lowest setting) and color saturation also increased. As a result, i see bandings or lines where a color gradient exist. I added an example photo from "Samsung Apps" page. You can easily see bandings on the bottom. I see such things in a PC screen if color adjustment is not optimum. So there must be a way to adjust screen saturation and brightness by a software through registry i think. It seems like a software problem. I think it is a very rare problem, i found few people on the web complaining about it. Mostly HTC Desire, which use also Samsung Amoled screen, users complaining about it.
I did everything said on forums to solve it but no way. I flashed many different roms both eclair and froyo, use a software given in HTC forums to change RGB color, changed color settings through video player etc. Nothing worked. Please help

I looked at ur pic. I honestly dont see any problem with it. What is this banding ur talking about?

Bottom of the screen, around "2010 Samsungs Electronics". This part should be a smooth color transition from blue to transparent but there are circular lines between colors. Is your screen the same.
Another example. The one on the phone looks white on the upper part where a color transition from dark to light black exist and there are visible lines. But normally it was looking like the other picture (taken from notebook screen) before this problem
ah on that screen i already see 8 shades of blue, most be around 4k colors .. bummer though, it's normally a software problem, doubt that a conector has come loose. (but possible if it's a pimped up composite plug with Y/Pr/Pb, .. eh still impossible cos it's getting decoded before that)
or my screen have problem.
download display color test from market or any other aplication
set your display light to manual and lower one possible.now open display color test, or any other picture and you whil see.... some orizontal lines like gradients.
(for me i can use a lower light to 40 %).
tell me your experience.
please.
Light lowered as low as possible... no probleme here
With some less intensive colors I could make out some kind of lines but I had to watch pretty closely to notice them. If I hadn't been searching for them, I probably wouldn't even have noticed. So it's nothing I would worry about, unless they are more pronounced for you.

for me are pronunced with lover ligt
same here, especially for grey colors, i noticed this first in the application "Programm Manager" (German TV guide) at the home screen.
I have a question about the screen on the SGS, i just got one and when i look closely on the screen I see small dots. Kind of like a chessboard feeling, I noted it first when I looked closely at the "Application" ikon in the bottom right corner. The four white fields look almost like small chessboards except that the "black" squares are more grayish and not black as in a real chessboard .
I'm wondering if my screen is somehow faulty or if it is supposed to look like that?

Try to do a screen test. Type in the phone (*#0*#)
okey, what am I looking for in the screentest, I have done that before, as I recall there are just at series of color test, the pattern im speaking of is on the whole screen, almost as if it was low resolution or something, I saw some information on a thread about this, but I cant find it anymore.
Bring it to a service center/phone shop, compare it to whatever display models they have? If you see a difference, you can turn it in on the spot

That's called the pentile effect. Just google pentile. Its how it is there is nothing you can be about it, although from a normal distace you can't see it. Its most visible on gray i think.

Listen to this guy.
Samsung used a pentile matrix (one pixel now consists of 5 sub pixels - 2 small red, 2 small green and 1 large blue) for some strange reason. I'm only taking a guess here but I figure it has something to do with the way OLED screens degrade. Blue degrades the fastest so I guess it makes sense to have it the largest as it will then have more "say" in the colors that are made. This is the same reason people complain that their screen is blue when it's supposed to be white. It is this same layout that makes the grid pattern and text harder to read than retina displays.
Thank you for the information, I was worried that i had some "resolution" issue. And true enough at normal distance it's no issue. I only noticed it while comparing some stuff to a friends iPhone4.
I have a buddy with a SGS, gonna compare to his "just in case".
I've heard people talk about dithering so I thought I might as well ask, for example while starting the samsung app the blueish background image is indeed dithered on my device, is that normal? Also when playing a video (stock player) the menu where you can scroll consist of lines of gray instead of being smoothly gradient.
i have this gradient issue either. there are steps in color gradient, is this normal??
for example when u look at the grey parts of the battery when ure charging the phone while it's off. or the samsung apps loading screen. and many more...
Hey fellas,
i didn't find any quite interesting LED mods / apps.
Tbh, we have this great light on the bottom, but it's quite useless if not for the notifications.
Where are the apps that would let me configure the light like i wish?
So for instance, if i'm unlocking my phone, playing around, writing messages, whatever, i would love to see
the light configurable?
It's just for the music and picture albums at the moment. And like i said, for the notifications in standby.
What i'm saying about "configurable" is, that it should be offer different options like a colorchanging mode, so all of the RGB colours would be changing over time like a rainbow? I don't know what exactly the possibilities are in terms of a smooth transition with this light but i think it would be looking really good.
Quite an eyecatcher. But i couldn't believe that no one has ever done such a thing for android phones. At least for lights compatible for the xperia.
Or did i miss something?
I would do it myself but i've got no real coding skills.
All i can write is plaintext and maybe "hello world"

Hey mate, Light Flow just offers me some options for configuring the already included lights like for messages or missed calls.
I'm looking for more advanced stuff like a smooth color transition (if possible) while the display is on or something like that.
Would be also interesting what the LED is capable of. It's just one LED right? So mixing colors would be hard, but if some possibilities are there, why not using it ?
The device is still very young but maybe there are or will be coming some apps or mods, even if they are integrated on some roms.

i can't seem to find a topic like this and it ****ing bothers me, why tf is nobody talking about the frontal led or whatever that is, so if you open the camera app and change let's say from back camera to frontal camera, there's a strip of light beneath the frontal camera that flashes, i've taken a closer look and it doesn't seem as a display thing, it actually looks like a proper led strip, why the **** can't we use that as our notification led? so far i've only seen it being used when you change camera modes, which is pointless, why not give an option to use it as notification led? and the second question, why the **** don't we have an option to change the back led's notification color? unlike some dude who said in another post that the led itself can't display different colors, i have no ****ing idea what phone is he using cuz mine has a lot of colors, like charging is yellow, calls are blue, messenger notifications are green, if you put on that flicker allong the song thingy there's the whole ****ing rainbow, so i know for a fact it CAN display different colors, now what i didn't get is why not having an option to choose what colors to display, like for example, change the calls to green and mess to blue? maybe someone can answer this questions to me cuz atm it seems pretty ****ing dumb to have the possibility yet not have an option to either use the frontal led which ****ing DOES exist but is used only in the camera app from what i can tell or change the back led's color which it CAN ****ing display yet there's no option for it, and thanks, sorry for being a lil butthurt but damn dudes this drives me crazy
That's not LED, it's just onscreen animation. Dunno about your other questions.
oh, thanks for the reply

The reason could be a lot of phones don't use a led anymore is disappearing like 3.5 jack.
Since my last phones where Motorola I don't have any led about 5 years ago, you can put on always on display the real icons of the app at least for me is better because you can really see what app is showing a notification and choose if you wanna check it or not.
Useless and agressive post. Build your own fu***g phone with all your f***g suggestions.
Could it be the proximity sensor? lol
I'm crazy about that switching-cameras led animation too dunno exactly why nobody is talking since it's goddamn beautiful. It seems that the animation is attached specifically to the front camera, because if you let the stock camera in front camera when leaving the app, when you return to the camera app, it triggers the animation as well (it works when in lockscreen too), if you use face unlock and do what I said before, the animation triggers as well. Perhaps we can see the option for that to become a notification LED as the developing scene for the device becomes better, but maybe u could express your idea in a much more polite and less agressive way lol
