Been searching for a while trying to find some info on the color depth on the Super AMOLED screens on the Galaxy S line.
Reason being, I have to be very wary of what wallpapers I use on my phone, because many end up looking very bad. You see distinct lines in various gradients as if the color depth of the screen is just very low.
It's a little disconcerting, and confusing, given how great these screens are supposed to be.
For example, there is a new wallpaper Android Central (posted just the other day) featuring their new logo/mascot. The wallpapers looks fine on my LCD monitor on my computer, but when I put them on my phone, I see lines in the background gradient that shouldn't be there. It doesn't seem like the screen can render those 'in-between' colors.
Anyone have any insight on this? Is it in fact the screen? Are other phones like this too?
I did read something about the fact that Android 2.1 maxes at 16bit color but 2.2 remedies this limitation, but I'm not sure if this is accurate, applicable to the situation, or even true.
Thanks in advance.
Download the Acquarium free live wallpaper in the market. The colors look amazing on my phone. There's also the Avatar movie, in the bright scenes the colors really "pop".
Let's hope froyo adds that feature, I've noticed it too on some colors, but its a minor annoyance, I'm sure if android supported larger screen resolution like gingerbread will have, samsung would have put a 1280x720 screen in there. Maybe the S2

As a photographer I put several of my Hi Res works on my Phone. I did not even downsize them and just moved them to the phone so they would not be downsized automatically. I found the Gallery displays them perfectly, all be it with a slight over saturation. But the depth is great, really really good. I have used it as a mini portfolio, its that good.
However if I make any of them a wallpaper the phone dummies the shot way down and I loose sharpness, pixel depth, contrast, even that over saturation I spoke of. Its seems to me the shots are forced down to a "good" wallpaper size to not drain resources maybe? If a large hi res photo is not down sampled in small increments a little at a time it looses a ton of quality. But should not shots made for wallpaper from the market work well too? Maybe the Vibrant dummies all shots down for the wallpaper since all screen sizes are different?
Now if I could only get the Gallery to stop hanging on start up after the Ji6 update...ugh
It could be the stock gallery app that is ****ing up the wallpapers. I recommend using an app called "Wallpaper Set & Save" which allows you to set any size wallpaper without ****ing up the quality. Zedge is another great app with tons of dope wallpapers and doesn't destroy the resolutions of your wallpapers.

Cool! apps like that I was not even aware of. thanks.
I just tried Photoshop Express app for Android to set a Hi Res pic to wallpaper. Fail. It down graded it substantially, It must use the crappy internal phone method also. Gonna check out the recommended apps thanks.

Being a home theater enthusiast and calibrating every hdtv I've got me thinking if its possible on android too. And I don't mean the sensitivity or the like. I mean video as in color and brightness. I watch alot of videos and to my experience both are off. Brightness is way too low you can't make out details in dark scenes. Some would say the color is oversaturated... it isn't. Brightness is too low making colors seem this way. A few notches in the brightness scale should take care of it. Anyone know if its possible?

Try manually setting your brightness settings in SETTINGS->DISPLAY->BRIGHTNESS?
I'm a professional video editor and I'm not THAT crazy about having perfect settings for watching video on my phone. Why? I'm usually not in ideal viewing conditions to watch an internet quality video for a few moments on a 4 inch screen with a dinky mono speaker.
Although, I know a few Apple Engineers in Cupertino that are REAL geeks that put bars and tone on their iPhone to just show off.

It's in vision kernel.
I was thinking of having my Windows desktop show on my Epic's screen using a VNC client. Plop the colorimeter on the Epic, and run the color calibration software on Windows. That would generate an ICC profile for the Epic's screen.
The next question though is how do I get the Epic to apply the ICC profile?
And in case you're curious, my colorimeter measured 7730-7740 K for pure white on the Epic's screen. So yes, it's rather blue.
Yea, nothing personal to the OP, but the colors are most definitely oversaturated. Has nothing to do with the brightness. Samsung, being a display manufacturer as well as a phone manufacturer, has display manufacturer tendencies. One of which is to oversaturate color on a display in order to give a "wow factor" to indiscriminate purchasers who generally assume that brighter and more vivid are better. Every amoled display used on a phone to date has had blooming out the wazoo. Not to mention how ridiculous skin tones look in photographs. I also wish there were a way to calibrate these things. I use a Thunderbolt which is now exhibiting some of the same issues with it's SLCD screen. Although I'm pretty sure that all they did was take the screens used on the EVO and pump up the color saturation. Guessing that's internally what the "S" stands for. The whites are nicer on the thunderbolt though, so at least I get that I guess.
Hey guys i have pictures i cant get display the full pic because when you set a picture as a background it will only allow you select like half the picture to set as a background is there anyway around this?
The picture size you select must maintain the aspect ratio of the atrix's screen. Its 540x960 pixels, or a 9:16 aspect ratio. Either find wallpapers of this resolution/aspect ratio or be stuck "cropping" your wallpapers. I hope this explanation helped. If it did, hit thanks.

P.S. I use Quickpic for setting wallpapers because its crop tool is smooth, and it never degrades the photo quality like the stock Wallpaper Chooser does.

Banding, otherwise known as contouring, is a digital artifact common to images, displays or apps of 16bit(thousands of colours) or less.
Gradient image
Viewing the 24bit image in the above link will not show banding on a 24bit display(3 x 8bit channels of R, G & B millions of colours) if viewed in a 24bit app.
If 32 distinct bands are seen, possibly with every 1/3 band being a green shade, then the screen or the image viewing application is not 24bit capable.
Viewing 16bit or lower resolution gradient images on your screen will also show banding.
The Android browser shows banding with this image while the Dolphin HD browser does not.
In short, the SGNote has a 24bit display, which will show banding if viewing 16bit or lower images or using a 16bit or lower viewing application.
More on screen bits
Im noticing lots of banding in lots of different apps :-/
Same here, also happens with Google apps like the Market. Not sure what we can do about it anybody has suggestions?

At least it is not the Note's display hardware that is the issue.
ICS may upgrade some Android OS apps to 24bit.
Thank You for this
This proves that Apps that display banding simply aren't rendering at 24bit.
I was leaning towards there being an issue with the screen as this problem was not noticeable on my previous android devices.
This clarifies everything.
Thanks.

You are welcome.
It bugged me too, until I got to the bottom of it.
Trust your eyes, the screen is glorious.
I too don't believe the hardware to be the issue. I suspect it's more to do with having a device with a smallish screen and a large 1280x800 resolution. Higher res images and videos look amazing. If the image is quite compressed (i.e. lossy) then the higher resolution screen will show this more than a low resolution screen. Garbage in, garbage out comes to mind. We need all apps and videos and images to be high resolution 24bit minimum to make the most of our amazing screen .

ha ha . Listen, think of it like this. You've probably got a high resolution monitor attached to your computer. Do you prefer watching videos at 420p and lower or 720p and higher? No doubt the answer is higher resolution to match your monitor.
What Samsung has done is squeeze in a screen with similar resolution to a 13" laptop, but in a 5.3" mobile device! So we're going to come across lots of images and videos aimed at 'normal' mobile devices, which won't look so great on our high-res screen. To make the most of the screen you can copy 720p or 1080p high profile videos to your sdcard, and they will look incredible on playback, but they will also be large and it's a slow process, and if the video is long then it'll also hit the limitation with FAT max file sizes. Those issues aren't the fault of the screen though. It's simple really. If you want to make the most of the screen density then you have to provide it with good quality source material suitable for a high resolution screen.
Do you think that its just software? No hardware? Do you think that ICS will fix this?
I came from dell streak and its realy hard to watch on note specialy on dark scene.
even opening xda app it has banding problems

It's definitely not a hardware issue because the screen is definitely 24bit colour. It displays well in the right app. You could swap apps for those that handle higher bit images. If you use Dolphin HD, possibly other browsers, webpages are seen in 24bit, if they are 24bit images. I don't know but there must be alternative picture viewing apps. Dice Player is a high res video viewer. As for system graphics, they don't look so bad to me. For games etc, it means living with banding until the maker upgrades? This is always the case on computers.
Be thankful Samsung have not rorted us.
Apple has ripped off it's customers many times selling lo-res screens as high res:
"Apple has received a new class action complaint alleging the MacBook
does not support millions of colors, but rather 16 bit color, which is
dithered to approximate millions of colors."

I don't have a Note yet, but can somebody try with QuickPic, it has an option in it's settings to force decode in 32bit mode.
That could clarify if it is a software or hardware problem...

The video and photographs shot with the phone's own camera have the same problems as other video and pictures. Surely they should display OK.
Some Android apps only render in 16bit

The phone has a 24bit 16 million colour display.
Some apps, including the picture viewing gallery app do not display 24bit colour in the 24bit quality they were made. See here
Thanks, Xaddict, this all makes sense regarding 24- versus 16-bit rendering.
Still, shouldn't intelligent/adaptive codecs be able to bridge the chasm by re-rendering 16-bit source material into some sort of "interleaved" or "inferred" gradual gradation or gradient... a codec to "smooth" the blend, if you will.
It's a codec issue, isn't it?
I wonder if Samsung or ICS will solve this first, if ever...
It feels like the Note has the same display like the first Desire (Amoled) that I've owned.
Its been said that this is a software problem, I've never seen this fixed with a 3rd party custom ROM since the Galaxy S1 days. Even 'x' ROM still shows color banding.
Found a solution for the wallpaper. Install MultiPicture live wallpaper (free from market) Go into it's settings and select "Color depth", then select "True color (24-bit). If the image you selected and used is 24bit, there will be no banding in your wallpaper. Hope this helped, cheers
Depending on the wallpaper you'ed still see massive banding.

It's not a software problem.
If anything, it's a low quality image being viewed on a 24bit screen problem.
Anyone else have color banding on gradients?
Like the stock wallpaper for example. I don't think it's supposed to be like this.

Yeah, I noticed it on the wallpaper too. Its probably due to the high PPI of the display and the low res wallpaper The is also some banding on the settings menu.
Same here.
It's normal. Pretty much every display is affected by banding to some extent.
To make this less obvious Google should use a solid background in place of the gray gradient (mostly seen in the Settings menu) as well as not shipping the N7 with low resolution, macro blocked, highly compressed, gradiented wallpapers.

I guess that's true. It's a bit obvious though.
You want to see banding? Look at the Galaxy Nexus. People were returning their devices because of it.

Anyone else have an issue where the lockscreen wallpapers aren't crisp and sharp looking? Seems like android compresses the wallpapers and they never look as good as the original image. I've tested out the new moto x and the stock wallpapers look tack sharp on the screen. This isn't just the lockscreen that's giving me this problem, it's the home screen wallpapers as well.
I've tested 1440p and 4k wallpapers as well with the same result. No, im not using low res photos.
Any ideas?

I've tried this, and still no luck. Wallpapers on the Nexus 5 are tack sharp, same as the moto x 2014.
The images in the gallery look amazing, but when they are applied as a wallpaper they look compressed and
blurry, even when they are cropped to match the 1440p resolution. This isnt a huge deal, but just wish it didn't look like this.
This is True
I am going to buy Galaxy Alpha .
and when I looked at wallpapers on home screen and Lock screen on my friend's Alpha it really looked pixalated
I thought its because of 720p and 316 ppi .
but when I checked Gallary app and other apps pics and resolution was looking really superb .
I can see pixels only if I really look Deeply .
2k screen is wastage of battery , Frame rates and performance , specially on S805
I hope they solve this Wallpaper problem
I can confirm this, I've compared a 1440p pic on gallery and when I set it as a wallpaper, as a wallpaper it definitely doesn't look as sharp as when I opened it in gallery. hmmm I hope they fix it with a firmware update or something. Don't know if it has anything to do with this issue but did any of you guys try a different launcher to see if the problem is solved?
Pictures look better in Gallery if you're using Adaptive display mode, because what this mode does is increase sharpness and saturation when viewing images and videos.

I go back and forth between basic and adaptive display, same issue on either display mode.
On both my Moto X and Moto G, whenever I apply wallpaper through Zedge the wallpaper image looks sharp but when I downloaded the same image and apply from photo album the resulting wallpaper looks like their image quality has been reduced. The effects are really noticeable since it produces color banding.
I'm using both stock Moto and Google Now launcher, both have the same issue so I guess it's not Touchwiz related. If anyone can help in pointing to apps that will allow me to apply my photos in gallery without reducing quality I will be grateful.

Yeap... That's it. Thanks a lot!
An easy way to have the same effect on the homescreen wallpaper, is to open the image with studio and apply the Sharpen effect (100%). Then save as 8MP> and set that image as wallpaper. That image will have noise in the stock gallery, but when applied as wallpaper should look almost identical to how the original one looks in the stock gallery.

I have no problems with wallpapers.
I edit them to an ideal size, which on the note 4 is 2880x2560 for AOSP-based launchers(scrolling wallpaper) or 2560x2560 for touchwiz/lockscreen.
I then set them through FX File Explorer which doesn't edit the image unless it's really needed.
