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)
I've noticed on my 8.9 Tab as with lots of recent other Samsung Tabs (the 7.7 included even though its an AMOLED) that the display basically has a yellow tinting.. no, actually, its all yellow. there are no whites in this tab, just yellow. Ive seen others on display at stores and to a more or lesser degree they are all like this. You can tweak somehow the display characteristics under the MODE in Display options but that really only makes it worse (choosing the MOVIE mode makes it even worse).
I had THE VERY SAME PROBLEM with my Galaxy Note (along with countless other people) but fortunately there is a app written for it that fully adjusts the RGB values, change the sharpness and color temperature for Dynamic, Standard and Movie modes. Its like magic and is not not a service or background process, its written permanently into the system's settings and done!
http://forum.xda-developers.com/showthread.php?t=1366280
Unfortunately this app doesn't not work with any other device Ive tried.
Now, there are a few (lame) apps on Google Play that allow for some degree of color correction but none of the really cut it.. by the time I add more Blue and Red and reduce contrast to tweak the yellow cast, lower gamma tinting appear and the yellow is still present. Is there a proper way to color calibrate the display on the 8.9 via software, editing props or changing code that gives instruction to the display hardware's characteristics?
The people at Samsung MUST be all blind to this on just about all their Tabs. I must say, as much as I detest the iPad, color-wise they are ALL always spot on! I am yet to see one that is yellow..
Thanks for the input!
Hi everyone!
I am a happy owner of AtrixHD,but two things I do not like:
1.Color boost technology of display.Such colors are acceptable for gaming,web browsing e.t.c.,but playing video and watching foto give very unreal colors,oversaturated,especialy pink(red).Definetly,there is no color adjustment in stock roms.Is there any chance to adjust colors(especially their saturation) within the settings of any custom rom or kernel which are discussed in development section?
2.In low light conditions(for example:small room with one window in cloudy day)my stock camera app is givng a spot with more pink color in the center of display,same spot appears on foto.All other camera apps from google play have the same spot.With normal light conditions everythig is ok.Does anyone has the same?Is it a hardware or software issue?
Thanks in advance for all replies,this i s a great forum.Sorry for my English,I am from Ukraine,Eastern Europe.

I know that ParanoidAndorid (not ours, OFFICIAL PA) uses custom color tweaks in their Nexus kernels. There might be a way to something similar for us, but I've never looked into it nor would I know where to start. Defy CM's were\are able to run color filters via software, not what you're looking for, but it does mean that its possible to tweak the display levels via software.
I've never had the pink spot issue, not in low light or good light. My low lights are just washy and kinda crappy, but no spots. HDR does much better in low light, sucks it doesn't work on 4.2 . HDR does look a bit oversaturated so you might not like it. Might be HW, might not be -- can't really say with any certainty.
My 10+ arrived yesterday and so far I've been impressed with two exceptions. As mentioned in other threads my finger sensor leaves a lot to be desired but my point of this thread was about an odd look my screen had. It was not bright and sharp like my 8+. There was a yellowish tint. I went into the 8+ to see if there were any differences in my display settings and I fixed the problem my by changing the screen mode on the 10+ from natural to vivid (Settings > Display > Screen Mode). The options were different on the 8+ but on the newer version it's one of the two, vivid or natural.
Just wanted to share that in case anyone else is having the same issue.
One question. My 10+ came with the screen protector and I've never had one. I assume they take away at least a small percentage of your brightness and clarity? I'm tempted to remove mine to see.

Keep in mind that Natural should follow the sRGB color space. Most displays have default colors that are too cold/blue (high color temperature, and I know, it's counter intuitive but that's what they call it ). Relative to "colder screens", sRGB will seem warmer / more yellow. But it's also much more accurate as far as color representation goes, and should be closer to what you see with your eyes unfiltered by sunglasses. This assumes whatever image you're looking at is also taken with neutral colors and not over saturated.
I usually calibrate all my screens to have more accurate colors, at the expense of that "pop" you can get with AMOLED screens.

That "pop" is exactly what I'm looking for so would you suggest I stick with vivid? I understand what you're saying about the colors but it's not an area I'm real familiar with. I'm just not seeing a brightness on the level I prefer and yes I have it set as high as possible.

Yeah, you'll want to leave it on vivid if you want that "pop". I also know that when my current Google Pixel got the Pie update, the auto-brightness was a bit finicky at first, as it's an "intelligent" brightness and it takes a few days to learn your preferences for the right brightness based on the lighting conditions. So that might be the case with the S10 as well, and I should be picking up mine tomorrow so then I'll know more about how it works exactly.
Also I think I read somewhere that the S10 will only get very bright in direct sunlight if it's set to auto-brightness. You apparently can't set it to that level manually. So perhaps play around with that a bit.
Any news on this? I just picked up my s10 plus and the screen has a yellow tint and seems less bright compared to my note 8...not sure if I just ask for a replacement. Thanks!
I always run mine on Vivid and WQHD and as expected the S10 is spectacular

im surprised there isnt adaptive display mode like on the previous models this really made different colours pop. mine seems to have a bit of an orange tint
I also found it too yellow.. Go at the advanced settings and reduce the green close to the minimum and the red just a little bit. It will look white again..
Because of the sun light some people find yellowish colours more natural..
Yeah the whites don't look good on the s10 compared to my note 8
Just compared mine with different demo models and they all seem a bit more 'natural'. No need to swap it for a different one, allthough they all are a bit different...one more leaning towards blue white and the other to yellowish white.
Well coming from pixel 3, to me, Colors looks natural. S10 screen is crisp and clear. Nobody can best sammy when it comes to screens. I am using natural mode. Vivid mode is having too much pop.

So even I had the same thoughts when I got hands on my S10+. Was worried the screen had some issues and hence went to the Samsung store and compared with the display phones - there was no difference between what I had and the display ones. However, when I compared with my S8+ I found that S8+ display was more blue-ish than S10+. The response from Samsung was that by default Samsung had toned down the blue light in the S10 screens for improved readability.
However, I feel the colors had lesser contrast in my S10+ screen compared to my S8+ and that is a bummer - at least for me!

I have found that applying "blue light filter" and setting it's effect to minimum fixes the color saturation and reverses the washed out look on images. Another way is to go into visibility enhancements -> color adjustment -> then either apply a filter there like "Tritan" or "personalize color" and follow the steps. To me I cannot see any difference between the above steps or just simply applying "blue light filter" set to minimum. To me both look to correct the color saturation about the same.
I hope this helps you!
Hopefully they fix this soon!

Hi guys. I think you might be encountering the display saturation bug.
The Galaxy S10 (USA Unlocked version in my case) has a peculiar bug in the display. When a photo is fully opened in an app such as Gallery, the photo's saturation becomes muted and cold (even with the display set to vivid and warm). It's very apparent with skin tones. I first noticed this when comparing identical photos between my S10 and S9.
If you hit the app switcher, the minimized card displays the photo with the correct saturation. Maximizing the app, causes the image to immediately turn washed out and Muted. This is appears to be a system wide bug, as it shows up in Gallery, Instagram and other places. I could not get this to show up with a screen recorder, since it's the display changing the image. I recorded it with my camera, but it appears very subtle. In person it is very obvious. I don't know how many are affected by this bug, but I'm seeing others talk about it on forums. Appears to affect all galaxy S10 models.
For a temporary fix, you can enable the blue light filter and set it to the MINIMUM setting. This will display photos in the Gallery and other apps with the correct color saturation. Hopefully Samsung will address this with a software update!

Hey all,
i was just wondering if anyone else has noticed that the vividness of the colours always seem to be more dull and washed out on custom ROM's as opposed to stock MIUI, anyone know why this is the case if there is anything i can do to improve the colours? I am running AOSIP ROM currently so there is no such thing as adjusting the white balance or the colours manually.
Cheers dudes
Hey,
I don't have such problems with my HavocOS.
But you may try changing the minimal amount of pixels to archive a higher quality via developer settings. But don't set the number too high. Try 405 first. If this is still too washed out try 492
