SAMOLED Screen, Colors and you.

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.

Low resolution lock screen pic

When resizing a wallpaper to use as the lock screen pic, there is some severe resolution drop.
Are there some high res wallpapers in portrait mode at native sgs2 resolution, maybe that will help?

If your wallpapers are 480 x 800, resolution is fine. Just increase the yellow frame to cover all the screen and you won't lose any resolution.

you can change the lock screen wsllpaprr ? how ?

Okay. I love the Earth wallpaper in the above thread. I have a cutdown version on my lockscreen. I can't get the yellow box to expand over the full pic. I absolutely want to take advantage of the screen and display the utmost resolution that I can on the lockscreen. What am I doing wrong?

The SGSII's resolution is 480x800. Since the Earth wallpaper is 960x800, you will only get the yellow box to cover half of it. You can't make magic resolution appear on a screen that is limited by 480x800.

Yeah, just choose some 480x800 wallpapers for lockscreen and you will be fine. 960 x 800 works for selecting background wallpaper when choosing extended view. Samsung's way of cropping/selecting wallpapers is a pain the @ss anyway. I gotta try at least 2-3 times until i am able to select the whole pic, most of the time i select a small portion which forces me to go back and select the wallpaper again

Background cm7

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.

Well what is anoying is if you use cm settings to set a custom lockscreen it will set the picture correctly and show the whole pic

Yep quick pic is the best for setting wallpapers. Default Android wallpaper manager always used to introduce bad gradients and I kept blaming Atrix for it but its actually the app.

[Q] Best Wallpaper App for N10

What is the best wallpaper app for Nexus 10?
Most of the common apps like Zedge don't seem to support the N10's resolution yet and the wallpapers downloaded from the web gets poorly cropped when applied as wallpaper ( tried using the Wallpaper Wizardrii) and looks horrible.

Simple Image Wallpaper Free
or
Image 2 Wallpaper
Those 2 programs worked the best in my experience.

Issue with wallpaper quality

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?

You are not alone. I have noticed the same thing. I believe its something with TouchWiz. I cropped my wallpapers to 1440x2560 in photoshop and they seem a lot better. Its funny how they still look a tad sharper in Gallery.

Anyone else with this issue / a solution?

No problem here, maybe I have the same issue but I never noticed it. . I also crop all my wallpapers to 1440x2560 and set them as a wallpaper using Quick Pic.

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.
Cheers

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.
