[Galaxy S II General] RogerPodacter:
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).
[Galaxy S II General] godutch:
Samsung uses a technology called mdnie to sharpen images, I suspect this technology causes the banding, also there is a separate profile for amoled screens because the older amoled screens were fuzzier because the pentile matrix (but of course not our samoled+) and they are using the old amoled settings
[Galaxy S II General] deanwray:
Interesting point, but how did you get the colour mode information from tapatalk?

Have to disagree, it would only mean that the transition of a single pixel line where the value changes would be smoother in a sub-pixel contribution sense (rather like anti-aliasing as a full screen setting (FSAA)). But rather think of a amazing 50billion colour capable screen (this is theoretical btw), and give it a full 16.7mil colour image. If there wasn't clever image processing and or filters active, then you would see banding if you look close due to many values of our high display not being activated. But on a lesser screen wouldn't look as bad because all the pixels show unique values. I guess the main factor on this would be the graduation over distance/pixels :)

It would be fair to say it's both a hardware and software issue, you can pretty much do anything you want in software or the video buffer b4 it gets blitted to screen. You could easy re-map the tone and value ranges of pixels b4 displaying them on screen though the video driver.

Now that is odd. Actually, thinking about it (and remembering reading the change log) the 2.3.3 sdk may default apps to 888 rather than the previous 565 from 2.2 will look into that

AMENDMENT:

Yes, looks as if a app that doesn't choose and just defaults, would be at 565 on 2.1, (some) 2.2 but 2.3 default would be 888
[Galaxy S II General] deanwray:
Interesting, but I do suspect (after reading a bit) that the filters of which you speak are only employed in Video Hardware Accelerated playback. Just like my lovely Samsung LED tv does :)
[Galaxy S II General] godutch:
On the old SGS it was used to make text more readable and was employed in many situations, at least that's what I have understood from voodoo color:

http://project-voodoo.org/color
[Galaxy S II General] deanwray:
Never had that on my sgs1, or rather, never had a contrast and sharpness on it like the SIMULATED shots :) Not saying it isn't true, just if I'd have had that, would not be a samsung fan and the phone would have gone back to the retailer :)

Actually, thinking about it, it may have been activate-able on any hardware accelerated surface (such as used to display web pages), but god, still would not have coped with that! So mine by default was off (although I don't remember disabling it) :)

Still think those shots of sgs1 defects are taking the piss :)
[Galaxy S II General] ithehappy:
You are bang on. It could be enabled or disabled on my previous Wave with a code, damn I forgot it, and it did make a heaven and hell difference on the screen color saturation and also contrast ratio. I hope if anyone able to find a such same code which will allow us to access through the service menu and change the Dnie technology to enable or disable to see the difference, we could have a new route to take from then.

Regards.
[Galaxy S II General] RogerPodacter:
I didnt know which the app was using, only concluding that the same app version showed banding and then didnt show the banding, all in the same day after updating to 2.3.3 and installing the same version of the app.

now this could explain some things if true and makes sense. still though the SGS2 is also running 2.3.3, and i refuse to believe that samsung's newer version of their amoled screens LOST screen quality/function/ability/whatever compared to previsou amoled's! i guess the only route is like you say the new screens are so good that the poor quality of these images is more visible on the new amoled plus because of its increased pixel density and larger size etc.

has anyone been able to use a test image and completely remove banding on the SGS2? maybe these test apks? or is it always there...
[Galaxy S II General] deanwray:
I could take a nice pic on 5dmk2 and look at not using any pallets or compression and dump that into a test app, but just about to go to bed, so would have to be tomorrow, if some1 msgs me and reminds me.
[Galaxy S II General] deanwray:
[UPDATED]

New test app with 2 images, no compression and attached for comparison, best to set display to 100%

I do see some banding on the left chest window on prime image :( hmmm

Also banding on either of my Tabs :/

Would be good if some1 could check on a nexus one or desire or something and let me know :)
[Galaxy S II General] godutch:
No banding on my slcd desire (also colors look much more natural on my desire, running 2.3.3 w/ sense btw)

edit: no banding on the prime image in the browser though (xscope)
[Galaxy S II General] deanwray:
You have both sgs2 and desire sat next to each other? and can see the banding on where I say, primes window etc, but not on the desire?
[Galaxy S II General] godutch:
yup, I saw the banding in the left window (it's only very slight) in the test app on my sgs2 (but not my desire) but no banding whatsoever in the browser
[Galaxy S II General] deanwray:
mother f*********it

Hmmm... what is your colour mode set to on the sgs2?

EDIT : don't matter I think that really is just for background :(

Gonna have to look at some more stuff here, I know the banding is tiny, but... I kinda want better :)
[Galaxy S II General] godutch:
did you try looking at those pictures with xscope? I see no banding in xscope
[Galaxy S II General] deanwray:
I just have now, seems that xscope uses some really harsh filters on images it pulls in. So in the xscope you actually looking at a very high SMOOTHED version.

Easy to tell is just zoom in, you can never get to a level where you see a 1:1 pixel relationship. Compared to PC/MAC or SGS2
[Galaxy S II General] deanwray:
[xscope]

look at the following image in xscope and try and find a true white black boundry, you can if your finger is panning the image, but not when you release

So just filters the hell out of it for easy on the eyes
[Galaxy S II General] deanwray:
updated 1st post, found lots of mdnie profiles, so gonna have a play later and maybe make my sgs2 look like it's been smoking weed while taking every drug under the sun.
[Galaxy S II General] vegetaleb:
Try Wallpaper Set and Save free app
[Galaxy S II General] deanwray:
for any reason ? Or you just want ppl to try it? Cause this isn't about wallpapers really :)
[Galaxy S II General] vegetaleb:
I had lot of banding with Nexus 1, the only solution to have full colors is to use ''Wallpaper Set and Save''.

Beleive me you won't beleive the difference
[Galaxy S II General] deanwray:
Does that app not just set background images? Just guessing by the name :)

Cause that aint really the issue here
[Galaxy S II General] jvidia:
Can you explain what you mean by ''Wallpaper Set and Save'' :confused:
[Galaxy S II General] vegetaleb:
It's a free app in the market, and yes it's only for setting wallpapers but at least without banding
[Galaxy S II General] godutch:
Yes and our problems are not only with wallpapers of course
[Galaxy S II General] zoobzone:
Great explanation, thanks.
[Galaxy S II General] RogerPodacter:
This app solved banding issues for n1 and others when your wallpaper showed banding. Stock wallpaper set had banding. Use that app to set the same exact image file not altered, and it suddenly had no banding. Kinda a different topic then this thread though.
[Galaxy S II General] RogerPodacter:
Well for what its worth I installed the updated app along my nexus one and have zero banding on any of the images pressing the menu button. Was that the correct result?
[Galaxy S II General] ph00ny:
I thought galaxy tab was using some fancy SLCD display.

Also similar issues with banding on SLCD implementation of HD7S compared against the old HD7
[Galaxy S II General] godutch:
Some piece of (pure)mind, puremind did a lot of testing of the display and says it has a very large color space and the banding most probably a software issue:

http://xdaforums.com/showthread.php?p=14739613#post14739613
[Galaxy S II General] deanwray:
Yeah, I know of the OLED gamut ranges, but that doesn't really explain why by default at mid range luminance on my little opt prime pic that I see slight banding. Although I'm coming round to the fact that it's a driver/pre-screen prep thing.

Still gonna look at these mobile dnie profiles though.
[Galaxy S II General] jvidia:
How is this issue going ? Any news? Any solution ?

What serve us a screen with such quality, if what is shown is crap? Still don't understand Samsung.
[Galaxy S II General] deanwray:
Haven't had time to play with mdnie profiles yet, and forcing 24bit mode on apps as far as I know is not possible and even if it were, would be a little pointless as many of those apps will be optimised for performance and either have corresponding bitmaps to that colour scheme or suddenly run slower.
[Galaxy S II General] jvidia:
OK ... but one noob question ... if this apps (ex: angry birds) don't run at 24bit mode, why the hell do they look better on other android smartphones like Galaxy S and HTC Desire HD ?

This is what bugs me ! At least I expect the same image quality (as to banding on gradients) in my SII as in those "suposed inferior" screens.

Or the android versions on those phones have something to smooth the original gradient from the developers?
[Galaxy S II General] deanwray:
Well, I would suspect that a full screen game kinda says sod off to android. So then your left with a custom engine using the GPU, and it comes down to video hardware decoding and compression stuff :)

Compare your sgs2 to sgs1 with my gradient test app that just uses android UI components, set both brightness to 100% then compare :) I did ....
[Galaxy S II General] jvidia:
I don't have here (now) one sgs1, but what did you find?
[Galaxy S II General] deanwray:
More detail and vibrance on sgs2
[Galaxy S II General] jvidia:
Ohh ok ;)

But with the actual aplication graphical quality, having one Super Amoled Plus is not so cool.

We will have to wait for something to happen is this department .... that's very bad IMO, because it could take days, weeks, months or even never change at all :mad:
[Galaxy S II General] deanwray:
well, all various sections to the apps that I'm doing look way better on sgs2 :)
[Galaxy S II General] jvidia:
A similar problem with WM7: http://asf-mobiles.com/2011/05/microsoft-reponds-to-post-nodo-16-bit-banding-issue/
[Galaxy S II General] valippo:
mhh, you know, I appreciate your effort to explain or justify the issue, but to me, the one who paid 600 euros for the best device on the market, the last thing I'm interested in is the reason why the screen is looking so ugly!!!

I just want to have a screen as beautiful as the others I've tried: Lg Optimus Black, Optimus Dual, Optimus ONE!!!, HTC Incredible S, SonyEricsson Xperia Arc etc.

Even the cheaper of the phones have no gradient issues...

What I noticed is that the GS2 has a banding issue on still screens but it gets even worse when you start scrolling between the pages...

Maybe I'll post a video to explain this better.

It's like the color depth goes even lower to allow better scrolling when scrolling between the pages.

So I guess this is something Samsung implemented in order to have the smoothest phone on the market!

What I really don't understand is that NO review has ever ever mentioned the issue!

are all the reviewers blind? or they are happy whit their free Gs2 instead?!?
[Galaxy S II General] jvidia:
x 2 :mad:

I think it must be something temporary before the real dual core suport comes in 2.3.4 / 2.4.

It must be some "cheap trick" to get better performance.

The reviews made must had access to phones without this "cheap trick".

This problem + the yellow left side problem + not beeing uniform with pure gray colors is making the SII the biggest "lie" in top smartphone market.

I'm very mad and disapointed at Samsung!

My coleage has one S1 and for the actual market price and image quality, it's a lot better phone.
[Galaxy S II General] Eggcake:
Wow I wanted to buy the SGS2 as a replacement for my broken Desire. This is huge and until this if fixed I will definitely not buy an SGS2. This is horrible!
[Galaxy S II General] jvidia:
Samsung fault or not it is really bad to have a high end phone with this and then see mid end phones displaying smooth IQ in gradients.

Another two examples ... PowerAMP Music Player and the game Samurai II Vengeance. Both have inferior IQ in my S2 that in S1.

The PowerAMP Music Player is so horrible that I had to uninstall it.

It has a gray gradient in the top, and it is so bad that it even displays greens in that gradient!

It looks like the charging battery logo, that displays greens in the middle of the gray gradient in the empty part of the battery.

Try for your self and see.
[Galaxy S II General] jvidia:
Can anyone confirm that Nexus S had also this banding issue before the 2.3.3 ?

If this problem is solved I'll become a happy owner ... even forgive the yellow tint problem :D
[Galaxy S II General] RogerPodacter:
we know for a fact that the nexus one had this banding issue, and google even told us that they fixed it in 2.3.3, and it is indeed fixed now on my nexus one. lots of banding that used to exist is completely and totally gone now.

i'm not sure about the nexus s.
[Galaxy S II General] Artius89:
Using the MIUI Rom from bmarko solves 80% of the banding problems ;)

So it's totally a software/driver issue.

Inviato dal mio GT-I9100 usando Tapatalk
[Galaxy S II General] jvidia:
That could also be one solution .... a really good custom/modded rom that forces everything to 24bit.

If I was the maker of a smartphone like the SII, I would be ashame to deliver a so week OS with this issue.
[Galaxy S II General] ZhuraYuk:
And what about video codecs? They too display in 16 bit. Whole image generated in 16 bit. Samsung must disable that DNIe **** that craping all image. Or they must must change some values in their graphics driver? I's source is open i hope? than some one must do it.
[Galaxy S II General] deanwray:
Erm, not actually 100% true, all depends :)
[Galaxy S II General] RogerPodacter:
I'd bet a lot of money that portion is not open source from Samsung. Stinks.
[Galaxy S II General] ZhuraYuk:
What you mean by "all depends"? Noticed one thing, in Apps there is much less bandings than in games, its wery much smooth compared to my true 16bit HTC HD2 display, when i zoomed images i can see some curious pixel rendering algorithm, that makes it less banded, it must be DNIe working. Well, I can live with that, but GAMES do not have that **** and looks identical to my HTC HD2! I guess Mali 400 driver works in 16 bit mode. It's crazy samsung engineers who placed Super AMOLED display for 16 bit colors.

P.S. deanwray how it is going with your app developing?

Hi all, sorry if this is the wrong place to post this, but I'm pretty new so I can't post in the development section yet. Anyways I'm running CM7 right now and ever since nightly build 91 the FFC has been broken. When you click to enable the FFC the rear camera just tilts its orientation. I tried going to the CM forums but it says "no bug reports, etc" in the nightlies section. It's not at huge deal since I don't use the FFC often, but I would think it would be something they'd want to know about or look into. When I go back to build 90 the FFC works fine. Thanks for any info in advance.
[myTouch 4G Q&A, Help & Troubleshooting] mark manning:
Im sure zinx is well aware of the issue. The nightly builds will almost always have something wrong with them. (I think they do that on purpose)That's what I find to be the fun with nightlies. One other thing unless your a dev posting a rom you should never start a thread in the development section.
[myTouch 4G Q&A, Help & Troubleshooting] DeadPlasmaCell:
Hah, Thanks for the heads up on that. Yea, nightly builds are great.. It's like X-mas every (usually) morning :D
[myTouch 4G Q&A, Help & Troubleshooting] mackster248:
It's because in the recent nightlies the CM team is implementing a new kernel, thus it's breaking certain things such as the FFC. But of course, it will be fixed in time.

I'm sure this new kernel will kick ass once they're done tinkering with it.
[myTouch 4G Q&A, Help & Troubleshooting] DeadPlasmaCell:
Aah, I didn't know that (Sorta new to the whole ROM, etc scene) That makes sense then, thanks for the info!
[myTouch 4G Q&A, Help & Troubleshooting] kimbernator:
I was getting a little annoyed by this too, so i reverted to stable 7.0.3. Then I realized netflix didn't work anymore, so I did a little research and found that I had made a nandroid right in the sweet spot between nightlies where both netflix and the ffc worked. I'll stick with this until this issue is fixed. I really do miss the brightness control on the status bar :(

This may (or may not) help - but -

Can you locate the source for "BatteryService" and see if anything in there helps?

Also - did the Asus "limited release" for the Dock issues not contain a working Dock Status? If it did, someone may have the files kicking around from that which could have the parts you need in?
[Eee Pad Transformer General] Bob Smith42:
I use a widget called "bat stat" that uses animation, but it does not handle the dock (of course). It is small, has great animation and graphics, and is not well know yet it is in the market.

Was thinking to do my own tf version, will let you know if succeeds.

Hope this helps.

UPDATE:

I finished the *graphics* to represent various tablet & dock and charging or discharging states.

I will look at some widget *codes* next.

No, because stock kernels do not have a bootanimation.zip. You need a custom kernel.

Hello everyone, by chance i got both the mobiles with me for a month

[i9003] and [i9000] galaxy S.

Comparison:

1. The screen of i9000 is better than i9003, but i9003 is more like true colours.

I9000 got a yellowish tinge on the screen,which is not that good !

2. Camera of i9003 is better than i9000, really.

3. Processing of i9003 is much faster than i9000.

4. Graphics of i9000 is better.

5. Battery life of i9003 is slightly better than i9000

6. Sound quality of i9003 and i9000 is similar, tested with several headphones on both, couldn't make out any difference.

NOTE: i9003 had xxkb3 firmware and i9000 had gingerbread latest 2.3.4(xxjvp)

IF ANY MORE DOUBTS, PLEASE ASK SOON AS I JUST HAVE IT FOR SOME MORE TIME !!
[Samsung Galaxy SL i9003] bprabawabr:
Wow.

I'd never thought the i9003 would win on so many aspects! I don't mean to insult you, but I wanted to ask several questions to clarify this matter (signed up as a noob :rolleyes: just to post in this thread :D)

- Are the two devices fair to compare? (In terms of age, OS version, apps installed and running in background, etc.)

- What are the symptoms that made you decide that i9003 has better processing power?

- When you said that the i9003 has better camera, what aspects did you mean? And is there any noticable difference in the time they take to shoot and save a picture?

- Have you compared the loudspeaker and the earpiece (instead of using an earphone)? What are the results?

I'm sorry for the many questions. I am very excited about this topic. Many thanks to you :D
[Samsung Galaxy SL i9003] falex007:
This sounds strange: If screen is better then it is better. BTW the different is not only in colors, but also in:

1. SAMOLED uses more power in white screen than SLCD (SLCD uses more power in black screen)

2. SLCD has better sharpness because of different structures of pixels

Look at these pictures (SAMOLED is in the left side)
