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

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)
Hey,
I really like the Gem Miner: Dig Deeper game but after changing the lcd density it's not working anymore.
My default density was 240 and i wanted to try a smaller one so i picked 220. But i noticed the game wasn't working anymore. I get a white screen with 1 brown block. So i changed it back to 240 but the game is still fckd.
Can someone please help me, i really like this game
I tried reinstalling the game and remove all app data stuff.
Nobody?
Damnit, i really want to play this game xD
I'll try to reinstall my ROM then and hope this will fix it.
hey, I had the exact same problem with gem miner, figured out it was the density issue, but you don't have to wipe or reinstall, you just need to enable compatibility mode in the density changer app. If the one you're using doesn't have this in options then get 'LCD Density Changer', has a little red screen icon, go into settings and check the compatibility mode check box and reboot, game should work perfectly now ;->
note: you can still have a custom density and the game will work with compatibility mode.
Hey I'm on 1.0.1 rooted and after watching peoples videos of playing say need for speed running full screen and when I load it up on my nook if does not fill the whole screen. They also appear to be on the Barnes and noble rom
Let me rephrase my notifacation bar does not go away so the app does go full screen but the motivation bar stays there(set at lcd density of 250)
Either Spectrum or Waveform, the effect is the same.
When I leave these wallpapers in the background, with no music playing, and slide from window to window, there is a glitchy artifact type effect within the wave that spins, but ONLY as you are holding your finger on the screen and mid slide. If you let go it turns to normal blue or orange solid color.
It kind of looks like when your graphics card is failing and artifacting on a pc. There is a wiremesh with flashy grids etc on the screen.
Just wanted to know if this is normal or if my phone has a problem.

Nothing to worry about mate. They look crappy on all phones.

Ok so I originally posted this question here:
http://forum.xda-developers.com/showthread.php?t=2556217
but I was told it was probably the wrong place and I should ask it in this section.
When I play some games, for example Paper Monsters, or Cordy 2, the game orients itself to landscape but upside down, and when I flip it the other way, the game keeps changing to upside down. I have no idea what the heck is going on!? The orientation and rotation settings work great for pretty much every other app, which means so far I haven't found any other apps doing this. Could it be a problem with the ROM I'm on? This is the ROM I'm using:
http://forum.xda-developers.com/showthread.php?t=2482192
There are some apps I can download from the PLAY store to help compensate for this issue somewhat, one I'm using called "Set Orientation" and it works ok but it sets the global rotation for everything, even some apps that shouldn't rotate. It's a decent bandaid I just have to set it to disabled when I'm using the apps that I don't want to rotate, for example, gravity / physics apps where you rotate and move your device all around to get maybe balls or particles moving in different directions. I would like a permanent fix however. Any help is greatly appreciated!!! :good::good::good::laugh::laugh:
I want to be fixed this problem.
Kindle 8.9 display is should rotate left-to-top, right-to-bottom. Official case is designed like that.
This seems in CM11.0 and CM12.0. Is there no plans to fix it?
