Blurry wallpaper

I know that someone posted a tread about this issue on XDA or some place else on the net, but for the life of me I can't find the thread now. I am trying to figure out why my wallpaper on my lock screen is clear, but when I use the same wallpaper for the Today screen the image looks grainy. Does anyone have a link to the thread that discussed this problem, or an answer as to why this occurs? I know this has been discussed before, so I apologize for bringing it up again. I am probably just putting in the wrong words in my search.

reaganh22, It was designed to overcome the exact issue that you're dealing with...the way sense doesn't display wallpapers you choose in full high-res glory. It takes a little learning, but it's awesome once you get the hang of it. Let us know if you need a hand getting it to work for you

Thanks so much guys! That was one of the threads I came across, but thought I had seen another one. It looks like this should do the trick though.

[UPDATED][EXPLANATION] Display Banding 16bit Vs 24bit (Video + app tests)

Ok, so there are quite a few threads about colour banding, 4 or 5 I think. All/most saying different things, sometimes the same things in different ways
Neways, although I really didn't want to add to it, I wanted to show everyone a few things about android colour.
Note: In order to really do these tests you need to set brightness to 100% so there is a common mark from which to draw any conclusions.
I believe the following:
1. It's apparent that super duper amazing amoled plus and then some Shows more detail (maybe due to sub pixel processing nature of the screen).
2. Due to point 1. and added to the fact that by default and quite often chosen by developers that most apps are set to use the 565 mode (5bits red, 6bits green (human eye sees more green) 5bits blue) or 16bit mode for performance reasons. With this we see banding in some colour transitions (More so green)
3. There are many bitmaps/images/textures that have been palletised in conversion and compressed for in-app performance reasons. This also produces artefacts that can be seen on our wonderful displays
So in collusion to those points it quite impossible to say banding is a software problem or hardware problem unless:
1. You wrote the app yourself and have forced the 888 mode.
2. You compressed the resources (bitmaps etc) yourself and know that they should be perfect while also doing point 1.
(NOTE: you cant just use a browser or image viewer to look at an image and say well that shouldn't look like that without thinking about all of the above!)
Ok so how do we look at these things?
Well 1st off, I'm doing an nice app with a theme framework that uses lots of bitmaps for the default theme, so I put in the ability to change from 16 to 24 colour modes, so I can allow users to pick from SPEED or LOOK preference! This shows how both the SGS2 and TAB7 can have banding on a drop shadow, or not:
View example (View the 720p)
Sorry about audio, couldn't be arsed setting up a proper studio mic!
Also sorry about the blur box I HAD to use
http://www.youtube.com/watch?v=8QlnuoNSdXo
OK so a few other tests on your own device
Test 1. UPDATED
Using the attached bandingTestUPDATED
Ok altered this little thing to show 2 photos I took, one of mighty mugs Prime!!! and one of a robin! The app forces 888 mode and allows you to switch images with settings/menu button. It displays at 100% so you cant zoom out or in, you can just view as is. For comparison these are the images in use :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Test 2.
Using the attached xda-gradtest
This is an app that is set to 888 and uses procedural gradients rather than bitmaps (as in the gradient is program generated rather than image based).
What you should see is only very slight banding in low greens due to our eye being very very very good at green colours compared with blue and red. There should be little or no banding on anything else.
More Info / Conclusion:
Well the gradientTest app is the best thing to look at, and the real test, the reason we see more banding on low green is 2 reasons.
The first:
Well we all see sh*t loads more green than any other colour (cause were ace) I recommend you look into human eye perception theory regarding both colour and detail perception as I have had to do over my many years in game console art development (wicked reading ).
Second:
I believe oled screens are not as good as others at low intensity low contrast due to the nature of how colour is processed.
I have many android devices ranging from the crappiest tablets you can buy of ebay, up to the best and even have iphone ipads also. I must say that with a finite gradient in 565 on the crap tablets and lesser displays, it looks better cause they are actually crap (dithered and filter to hell)
The same is true of this display I'm typing on now compared to another I have on my mac pro. One is an IPS pro colour variant of an LCD panel and one is not. Crap looks better on the lesser monitor! But Amazing looks amazing on the IPS pro panel that I HAVE to use for my 3D Graphics, Photography and Video work.
more..
If you plan to use apps that are set to 565, you have to deal with the banding or get a lesser display that just doesn't show it!
If you plan to use lots of apps (24bit)(888) that use low contrast dark green to black transition graphics, you will have to deal with the gradient banding
Alternatively
You could wait till the average target device has a minimum spec like the sgs2 and also a min OS of 2.3.* then probably most apps will have higher colour set and higher fidelity resources (bitmaps etc) in use But as it stands the mass market is much lower spec and the dominant os version is a mix of 2.1 and 2.2 devices
New info
previous to some 2.2 and all 2.1 android os defaulted to low colour if a developer didn't set it. Now in 2.3+ it defaults to high colour if they dont set it.
UPDATE 14 June
As some have mentioned (godutch etc) dnie (Digital Natural Image engine) by samsung is a colour/image processor that could be in use. Having looked at test 1 with the images, there is hardly any banding at all, but just a tiny bit I can see in primes left window. With this in mind and only mildly pissing me off, started to look at ROM and found many different " mdnie_profiles " that are apparently used and have different settings in each profile relating to all the major visual aspects (video, gallery blaaa blaaa)
So gonna have a play (these are in /etc/mdnie_* ) but I dont reccomend ne1 doing this unless you really know what your doing.
SO....
Hope this helps kill lots of thread activity on the same subject across multiple threads where info is getting hard to find and peeps just cant read all of those posts.
As always due to who I am I will say that I could be in part or on a whole wrong on this to any degree, but I believe this info to be correct as of the time of this post and this is only for the purpose of putting a few peoples minds at ease and also as information that doesn't sit 50 posts into some of these massive threads

Wow! I'm not a techie person like you but the way you explained it I kinda get the idea.. I'm very thankful for people like you who share their knowledge to educate us so we can come up with a decision whether to buy sgs2 or not. I'm looking forward to upgrade my Samsung i8910hd to sgs2 come July, and I'm researching in the forums to check the users' feedback as to their personal experience with their new sgs2.

As said above, I'm not a techie (Not as much as the OP anyway ) though am also grateful for people who post up tech info like this.
To the 2nd poster.... Ignore negative comments given by a lot of users, regardless of whatever bugs may be present, the S2 is an amazing phone and you will not be disappointed!
People are too quick too moan, yet don't talk about the plus sides

Thank you for the time and energy you put in to explaining this. It's sometimes hard to participate in certain technical conversations/threads because there are so many moving parts and so many different theories. This thread is refreshing.

But there's still very noticeable banding on 888. Less than 565 but there still is. So the banding problem really exists.

Read the post and instructions fully, along with expected results!! Cause if your talking about angry birds bg, then I explained that! So no1 knows what your on about unless your precise. I've yet to find a problem with anyones display in this manner, thats not to say there may not be a first, but you have to be clear and read properly, then I would look to do some proper display test apps.

I read everything. With Xda Gradtest the green has the banding issue, so yes maybe our eyes are more sensible to it, but that doesn't excuse it & the problem exists, the green banding on a larger scale can be very noticeable.

Well my samsung galaxy tab had the same problem with gradients and it just had a simple lcd display. So I believe the problem lays with samsung as no other device I owned had that issue.

Discussion apart ... what can be done in the firmware (by Samsung) to correct this problem with the actual 16bit "low quality" apps and OS? the OS can be improved, only depends on Samsung, but will we have to wait for the apps developers to give us better IQ in their future releases?
Thanks again!

Well the os supports full 24bit colour with another 8bit for various non-palletized blending modes. Thats just Android, but most of the base functions you see in android are indeed independent apps like phone, calendar, contacts etc.
So the OS is fine.
As for applications, to the best of my knowledge, you cannot force an app to be 24bit mode, but even if you did, as the test app shows with angry birds bg, the source resources (images, textures etc) have to be of a quality that fits.
So in short, nothing to OS, as for apps, ask devs to put more work into them to do different resource graphics and optional 24bit colour mode. 24bit switch is only in my apps cause I'm and artist If I were a full blown programmer I probably wouldn't bother Also the market figures say it would be quite a bit of work for a very very very small percentage of ppl

thanks we will have to await for developers to work better. At leat the apps included by Samsung should be 24 bits !
It's a crime not do do so in a device like S2.
A little off-topic ... as a developer I am I'm currious ... you developed those 2 apps in what language? .net + Android SDK, Basic4Android, ... ?

it does only on low luminance green, but tbh, it's on every display depending on how subjective you are. But the horrid banding ppl talk about mostly is not an issue if resources are good and app is set to 24bit.

..and where did you find a S-LCD version of GS II?

I was talking about my desire

a couple of points. the nexus one and other amoled phones all had horrible banding for the last year, till the 2.3.3 update, and now the banding is gone completely. for example the XDA tapatalk app splash screen had banding. once 2.3.3 came out, the xda tapatalk app banding was gone. the app did not change from RGB565 to RGB888, the OS itself was updated with "something" which we arent clear on.
now considering the super amoled plus display has MORE sub pixels than the amoled with pentile sub pixel arrangement, it would be easy to think that banding should be even less on the plus version since there are more pixels for the same resolution.
anyway it still doesnt fully explain why angry birds on a nexus one, or any other phone, doesnt show the banding. but it DOES show banding on the SGS2. its the same app version. also considering the nexus one WAS seeing banding on these apps, but since 2.3.3 update, that banding is now gone, it makes me highly inclined to say this is a samsung software issue.
for fun i installed the test apks on n1, no banding on minimum brightness on RGB_888 on either apk. of course it was there on angry birds background RGB_565, but playing the app itself does NOT show the banding (only thanks to the android 2.3.3 update).

black clipping, how to see it

Guys, here is a very easy way to observe the black clipping issue.
In your launcher settings, set your drawer to horizontal paginated and the transition effect to card stack.
Now, in a dark room, simply scroll through your app drawer from one page to the next....very, very slowly.
(This works best if you can scroll from a page full of icons, onto an empty one)
Watch the icons as they appear out of the black background, note how they are broken and choppy at first, only taking full form once sufficient brightness is reached.
I also have an sgs next to me, running ics sgs 4.2.... If I repeat the test the application icons fade away and reappear perfectly into the black background.
Its a very sad state of affairs......but it affects every galaxy note.......

I know, I dint mean it to be condescending. But if you searched, you would know, it used to be once oft discussed topic.
The recent CM9 and Stunner ROMs have subsided most of it, though some of it is inevitable. Samsung, unfortunately, dismisses it as normal. LOL

No offence taken. I'm aware of the history.
I'm keen to try the CM9 ROM, to see if it addresses the issue.

Anywhere you can select an option (dialog box)... ringtones, notifications, wallpapers, even changing volume shows a piece of discoloration..... increase brightness to see more discoloration.

I may be blind, but I'm totally not seeing what you are describing.

LOL!!, it looks like someone used an erase tool on an overlay on that asset then saved it (possbily accidently). it doesn't look like an artifact or anything like reported its actually part of the background asset HOWEVER i had never noticed till this post and now it annoys me :\

This is really great news... I just tweeted him on an ETA... I've seen bugs in Android, but this is one that you just can't ignore and should not even accept with how much we spend on our devices, and its plaguing my Nexus 4 & 7...

I have noticed this problem from the first day on the settings screens, there is a gradient from black to grey. And this was not this way in previous versions. If it is fixed by an update it would be great.

Damn! Ignorance is bliss, never noticed until you called attention to it. Now I cant stop noticing it.

He is the Android framework guy, I don't know how many times I have cursed his name during the work on my app.

Next patch changes

DISCLAIMER: Please don't ask for ROM, dump, files, where I got the ROM etc etc etc. Can't say anything and will ignore any requests.
Next patch version for the Z is still 4.1.2 but has some optimizations, let me name a few:
- Soft keys + notification bar background changed, it is now black and looks a lot better.
- There is an option to adjust the white balance of the screen
- There is an options to enable/disable the notification light
- Stamina seems to work much better, better standby time plus LED notification works with stamina on. Also noticed that apps in stamina exception list work much better now.
- WiFi reception is MUCH better.
- Camera opens faster than before, still a bit slow for my taste but it is a step to the right direction.
- The device is faster in general. Have tested this with another not updated device and it is in the scale of ms but still it is faster and more responsive.
I might be missing a few things here but it is a nice patch, I know it is not 4.2 but still it is a good patch.
Accepting questions to test things but I can't always answer very fast.
EDIT: forgot to write that the exploit for root doesn't work anymore.

Cool thank you Hopefully it won't be long until this is out!
Have they improved the camera quality at all do you know?

This is most likely real! Haven't heard all of the listed improvements but we received internal confirmation on most of them.
Does this one already include the proper Music Unlimited integration in Walkman or is that planned for another release? I know it's coming but never had any confirmation on whether that would be in 4.1 or 4.2.

- The device is faster in general. Have tested this with another not updated device and it is in the scale of ms but still it is faster and more responsive.
I might be missing a few things here but it is a nice patch, I know it is not 4.2 but still it is a good patch.
Accepting questions to test things but I can't always answer very fast.
EDIT: forgot to write that the exploit for root doesn't work anymore.

You forgot to mention that the display and colors look much better with the newer version (10.1.1.A.1.253)
Indeed, exploit root doesn't work with this version...
