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?

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?
Sent from my GT-I9000 using XDA App
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)
Hi Guys,
Just noticed today that towards the bottom of my screen, there are 4 light flares when there is a white background. The lights change when you change the viewing angle. Is this normal?? Does everyone else see these light flares??

LCD bleeding, maybe? Can you show me the pic?
Sent from my LG-P970
I'm not sure if it's LCD bleeing. I read that it's only against a black background. The problem I'm having is only when theres a solid white background and when you change the viewing angle, it kinda disappears. It looks like 4 tiny light bulbs behind the display.
Love this phone. But damn screen is already burned-in. Can see ghosting of the nav bar and clock. I'm sure a lot of us do.
Has anyone been able to fix it? I tried all those apps. Blinking colors, all whip_te, inverted. Nothing works for me.
Is there really a fix for ghosting on the amoled screen?

i should buy another phone?
From what has been doing the rounds, it seems as if the issue is real, but so far nobody has proved that it exists, with side by side comparisons showing different wallpapers or by playing videos.
Passing up on this phone would be quite unfortunate as there really is no true alternative to the Nokia 6.1 Plus, with bootloader unlocked, of course.
It'd be great if anyone could show how exactly the bottom area looks, on loading up different kinds of contents :fingers-crossed:

There is not light bleed. The light bleed that seems like is the navbar gradient on android oreo. I am a moto one power user and I assure you. There is no light bleed even at max brightness!
Some youtubers
Some youtubers done lcd test and we can see screen bleeding issue. On a plain black or grey background screen bleeding issue can be seen.
please, Prove it.
I tried, and i am confused

I got my phone 2 days back and the first thing i noticed was brightness on the bottom part of the phone (bottom part of navbar) was more than rest of the area.
I tried with 3 apps "Quora" "Whatsapp" and "Curiosity".
When i launched Quora, Navbar gradient was observed and it looks like backlight bleeding.
But when i launch Whatsapp or Curiosity, the navbar gradient disappears even at max brightness.
So i think this is not backlight bleeding, but i can't verify this with other apps, or even while watching videos on full screen.
this is definitely confusing. we need more data.
Bleeding
Backlight bleeding only visible on some background Colors. Is there anyone on Xda that can prove it that it is or it is not bleeding

What is there to "prove" ?
Take it from users who use the device daily. And coming to the YouTube reviews, aren't the review devices pre production? How good is the hardware there? The navbar gradient is implemented in a weird way by motorola which makes it feel like the light bleed in most of the apps. But I can assure you that its not there. I have tested extensively and you need to physically see it to understand the difference. You cannot visualise it over photos on the internet.
I mean if you people can remove that gradient and show us

Moto One does not have any such UI customization.

No, what i meant was..... Moto does not give any UI option to user to disable Navbar gradient.
It's either system controlled or app controlled, i am not sure.
And like i said earlier, its not visible in all apps. so does not look like backlight bleeding.
Screen Bleeding Issue Solved.
For those who are wondering about the Screen Bleeding issue with the #MotorolaOnePower Let me clear out this for you, Yes, screen bleeding issue is present and it is ARTIFICIAL. (I don't know why but it is) And can easily be fixed via software updates.
How to disable it?
Install "Navbar Apps" from play store and make the navigation bar colour to solid white/black to overcome those ARTIFICIAL SCREEN BLEEDING issue or wait for the #Android9Pie Which probably will fix this issue.
Hope it helps.

What I think to test it. If this is software based gradient or artificial then screenshot can capture it. If screenshot can't capture that gradient it means it is screen bleeding. Can anyone test it and upload screenshotss?

It's the same as we can see in screenshot and yes I never believed that it's an light bleed issue...!!
As I have tested the same with some display tester app but I don't see any light bleed issue with higher brightness whatsoever...!! So it's a intended UI effect and not an issue...!!

The gradient is an overlay applied on the screen. It is similiar to the Night Light feature, when you capture screenshots with Night Light on, you don't see it in the screenshot.
Hope that helped clear confusions!
