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?

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,
I have just purchased an HD7 and I really like it so far but I have a question regarding some screen distortion I am seeing when I scroll through menu's, apps, etc...
For example (and where it is most noticable although it does happen in other areas as well) when I go to the applications menu (where all apps are located to the right of the Windows screen) and I scroll through the apps from top to bottom, all the writing beside each app icon becomes so distorted while scrolling (almost static like) that you cannot even make out what the words are saying until the scrolling stops and then everything is ledgable again. Is this normal?
On my Galaxy S the scrolling does not affect the font / writing this way at all and even on my old Omnia i910 I dont remember seeing this type of distortion when scrolling.
If someone can please advise me on this I would really appreciate it. Is this normal for this device? Does yours do it? Anyway to fix it?
Thanks

It's normal behaviour but I'm not sure of the cause. From what I've seen, this only happens when using the black theme. If you use the white theme it doesn't happen.

Thank You for the reply. Really? Hmmm... That is odd. I wonder if this will be something that will be fixed in updates perhaps?
I use a black theme and this doesn't happen to me at all. Certainly not to the point it's unreadable.

Hmmm... Now Im confused... One person says it happens to him and one says it does not.
Do you experience any distortion of the writing in apps, etc while scrolling? It is minimal when I scroll slowly but when I scroll fast it is quite noticable.
PS... I did also try the white theme and it does not do it in the white theme as was mentioned by the other poster... Only in the Black theme.
I guess I'm not sure what the deal is. When I'm scrolling fast, it could be a million dollar screen with perfect clarity and I STILL wouldn't be able to "read" what was there. I mean, I have 20-20 vision and am a pretty quick reader and I can barely read my chat log scrolling slowly. When scrolling fast enough to "distort" you would have to be able to read about 120 words per second (I scroll through three screens worth of text in less than a second, about 40 words per screen). That's 7200 words per minute which is darn near World Record Speed Reading (not counting those who skim most of it and lose a great deal of comprehension).
I'd just like to say that it's not a major issue for me, but it does happen. When scrolling the app list, the text does fade out, but I don't really see it as much of an issue as the items are moving so fast that you wouldn't be able to read the text at any rate. As the list is alphabetical, I know where I need to stop, I'm not reading the apps one by one as I go along.
I'm not sure now if the OP is experiencing a different issue but he did confirm, as I have, that it doesn't happen in the white theme.

@Shadowise,
Yes... This is what I am talking about and again Thank You for your answers. I also really notice this when using the People Live Tile and especially in the synced Facebook listing. The text DOES fade out and the smaller the text the more faded it seems to become. Again... This is in the Black theme.
Also, I have noticed while in the People "hub" when scrolling from side to side that the screen itself darkens / dims out while scrolling and it also DOES this in the White theme as well. Is this also normal behavior?
If your not sure what I am talking about then please go into the People tile and just hold your finger on the top of the screen (where it says people in big letters) and slowly slide your finger and you will see the screen darken / dim out as it scrolls - unless there is something wrong with MY device in which case you may not notice what I am talking about.
Please let me know if this happens to you and if this is normal as well. Again... my Android does NOT do these things and so I am not sure if this is normal behavior.
Thanks in advance...

My screen absolutely does not do this. The people tile actualy looks sharper than the apps screen, regardless of how fast I scroll. The screen does not dim out _at all_.
Black background.
It happens over here as well this is due to Motion Blur, the quality of screen used by HTC is poor and this is a known issue with the HTC HD7 and HTC Surround. HTC should have used a better screen specially for its flagship device on the Windows phone 7 platform. But i guess thats the main reason they didn't; the platform is new theres no need to increase costs for a niche emerging market.
Ok... I am confused again... One answer says that this absolutely DOES NOT happen to him and another answer says that it DOES... LOL!!!
This happens because of the 4.3" screen. It's not the best screen in the world. The 4.1" dell venue pro screen never exhibited this behavior and when I switched to the hd7 I noticed it immediately.
It's called response time, it's not fast enough as some other screen, basically it's more prominent while using black theme because it takes full response time (i.e. 8ms) for a pixel to change it colour from black to white and then to black again while you scrolling.

The funny thing is that the more I play with it the more I notice that this only really happens within the stock Microsoft OS apps like People, Zune, etc. When I scroll through other 3rd party apps such as Facebook (actual app and not the synced version in the People tab), FIM (Facebook Instant Messenger), among other 3rd party apps that this fade out / distortion does not take place.
Anyone else find the same?
EDIT... I have confirmed the fade out / screen distortion to again seemingly only to be affecting the Microsoft stock OS apps again after going into Marketplace, Office, (along with the others mentioned above). It does not seem to affect 3rd party apps... Facebook, FIM, Yellowpages, YouTube, etc.
Again... Anyone else find the same or can check?

We're not talking about the whole screen, just the text.

Actually... I am talking about like 3/4 of the entire screen when scrolling from side to side in any Microsoft stock OS App.
Like I said in my previous post... if you go into say the People live tile and place your finger on the top portion of the screen where in big writing it says "people" and just slowly start to move your finger to scroll you will see the bottom half of the entire page / app dim out until you remove your finger or it completes its scroll.
As I said... it does this on my device in EVERY Microsoft STOCK OS app like People, Zune, Marketplace, XBOX Live, etc but in 3rd party apps it does NOT do this. This happens in WHITE theme as well.
To try and reproduce this please go to any Microsoft OS App like "people", press your finger at the top of the page and move your finger side to side in short movements and watch your screen. You should see the dimming effect unless my phone is defective or something.
Please tell me what you find.
i'm pretty sure this is not a bug or an issue, it's just intentional, and it's 100% a software thing, you can see that in many wp7 reviews...
but a different thing is the effect you see scrolling the applist, that one is related to the hd7 screen and you won't see it using, for example, an omnia7

Do you have an HD7? Can you confirm if your screen does the same "dim / fade out" thing in the Microsoft apps as I have described? Also... Why does it not do this in 3rd party apps then like youtube for example? I have even checked the HTC Hub app and in the HTC app store it does not fade / dim out but it sure does in the Microsoft Marketplace app. Weird.
As for the thing you mention about the app list and the screen - well that is my first big dissapointment with this phone. I have a Samsung Galaxy S and of course the SAMOLED is AWESOME but this phone is said to have the S-LCD (Super LCD) display which is supposed to be a pretty good screen too.
Well... I found a youtube link regarding the BLACK theme scrolling words distortion. Here it is...
http://www.youtube.com/watch?v=RperdOR8y5g
But I have not found anything about the screen fade/dimming in Microsoft apps so I hope one of you out here can reproduce it and tell me my phone is ok (even though it will still kinda suck)... LOL!!!

this is the full reason why ^
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.

Since I've got my Xperia T I have noticed a weird screen behavior I hadn't seen yet in any other android phone, whereas the device adjusts not just the backlighting, but also the contrast and the saturation based on the onscreen content.
I outright dislike it, as it's not seamless - you can actually see them slowly changing while you navigate your android screens, and it's not limited to photos and videos, as someone says. It's system-wide.
Just try closing all tabs in Chrome (remain with the dark chrome background icon), and look at the status bar icons: they are pale white, not bright white. Then open a browser tab and watch the address bar colors (sand, white, and black text), go through all of the shades of grey, before finally settling to the right colors. It's not just Chrome... every time your display shows a dark scene going brighter, you can see it happen.
Couldn't it stick to the max contrast and saturation setting, just like what we see in the photo album?
Alternatively, is there a way to disable the bravia engine and make my screen behave like all other screens?
Thank you for any answer

I never noticed it before but you are right, i see the same effect.
Even if i disable Mobile Bravia Engine in settings... now as i know it a bit annoying.

Apparently that setting affects just the Bravia Engine behavior when watching pictures or videos.
I did notice that behavior on my XT screen but i don't think it's a bravia engine issue, i believe is sony stock roms problem. Actually i'm on recCoba's curiosity Rom, wich has the same acreen behavior, but i don't temember too well but i think when i was on jellybam rom the screen was behaving as a regular screen but as i said i can't say it for sure. Someone with a CM bases rom could tell if that happens too on those roms
It has already been discussed -

Hello, who knows how to get rid of automatic color popping mode when playing videos, i ve noticed it on youtube.
Possibly by going into Setting>Display>Color mode & Temperature and change your color settings through there.
Yes despite activating normal colors setting, the color turns satured automatically when playing a video. That is a huge limitation. Weird from huawei

Looks fine to me, but I would blame the app writers.
Seems like the Video Enhance mode on Samsung S8/9.
