AMOLED is more colorful than Super AMOLED!!!

Hi , I'm Sultan.
I have 2 devices : Samsung Galaxy S i9000 and Nexus One.
when i open the same application in these 2 devices , like Talking tom
i got that Nexus one screen is more colorful and better.
when u open white pages , you will see SAMOLED is little blue and AMOLED is White.
SAMOLED is changing original colors of any app or video.
is there any solution for this problem. Like changing the colors temp to standard.
I want to fix I9000 screen.
it's like when u change the LCD Screen temp of colors to cold.
Thanks , Sultan

In my experience the automatic brightness is quite "low" (weak), and when I want to see beautiful colors I usually go in the Display --> Brightness settings and instead of auto I put it at max, then the colors are more vibrant than in any screen I've seen.

SAMOLED at full blast is blinding powerful colour show man, yesterday i was playing around with some system tools and the damn App set the display to MAX i was left almost blinded
the colours were amazing! at full capacity, my 1080p 25" 10000:1 LCD pale compared to the SAMOLED

And what happens with battery drain when brightness is set to MAX?
Big impact? Low impact? In the middle?

I would say that colors that S-AMOLED outputs are way more vivid than AMOLED screens.

PS
Although color temperature is different on the two phones.

Better colour temperature on the GS compared to Nexus/Desire, some may like the overly saturated look of the latter handsets however...

Guys , try to run talking tom app in both GS and Nexus one. And see who has better colors.
(( Is there any way to change colors temperature ? )).

I think there is via stock video player but don't know if it changes the entire color of the interface.
There could be a difference in running 3D apps, probably in different drawing of textures, I really don't know...

Actually, the Nexus one (and HTC Desire) screen is over-saturated, with a STRONG tendancy to orange/red.
When you open a white screen, it's a dim white.
When watching media/movies, SAMOLED gives a LOT more vivid and true colors.
If anything, the Nexus screen is "changing" the colors of every app.

Screen gamma test image, how low can you go

I made a test image to test how close to black your screen displays before clipping/cutting off. Display in any image viewer just make sure any brightness settings etc are all off/default/flat. Do the test in a dark room.
The numbers correspond to actual RGB values ie: 10 is R 10, G 10, B 10.
This is really effected mostly by firmware gamma curve settings not hardware.
The Note goes to 4 before cutting off, my Infuse goes dark at around 9! What crap gamma settings!
Theoretically you should be able to see number 1 (I could just make it out on my PC if I looked at an angle to the LCD).
How low can you go?

2 on my LCD
Freaking 5 on my iphone 4!

The Note cuts out COMPLETELY at 4, I mean nothing at all displays lower than that. It should gradually ramp to zero, not just cut out.
This explains the blocky tiles while displaying dark video. If there are shades 3,2,1 to smoothly blend they are not shown giving a stark defined tile.

The very dark shade should be explained by the encoding since Samsung uses a 24-bit display rather then a 16 or 32.

If you see the pic on the ImageShack site from your browser it goes to 1 if you DL the file and open then it stopes to 4 on the DL file it dissent scale as in the browser it prompt goes from light dark at 4 to black

I can see the 2 and almost the 1 in my note at minimum brightness. If you raise the brightness lower numbers become less visible as the border around them gets brighter. This display is very bright, I find minimum brightness more than enough for interior (home/office/metro/train).

I can see it till one

Same behavior with my note also, as Braxos noticed.
Can someone explain why the differences?
1. why through browser we can see until 1 and if we open the downloaded .png file we can see only until 4?
2. why the differences between galaxy notes? (some people here mentioned that they can see until 1 or 2 and some others until 4).
Thank you

Maybe the browser is changing the gamma slightly?
I would only trust the actual downloaded file viewed through an image viewer with no enhancements.
I am curious too as to why some can see down to 1 or 2. On mine there is a definate complete cut off below 4. Maybe different firmware versions are set different?
Mine is the Polish version.

use good image viewer this is the trick

Stock image bower isn't good ???? And browsers one Is better ??? Or.us it because browser has colors management on it?
Sent from my GT-N7000 using XDA App

actually never compared default viewer vs browser but i know default viewer is crap so i am not suprised browser shows better

I can see 1 in browser, and 4 in gallery. Below 4 it simply cuts off.
Maybe it's the same thing, as you set a black lockscreen wallpaper and desktop wallpaper, and the desktop looks good, while the lockscreen bad?

Cuts out at 4 in image viewer and 1 in the browser...
I'm guessing some people just saw it the browser and posted that they can see till 1...

The image gallery only displays 16-bit while the browser supports 24-bit. I believe that is why this happens.

I can see 1 in the stock browser but only 4 in opera. I didn't bother downloading and testing the stock image viewer but I suspect the results would be the same as everyone else (cut off below 4.)

Exactly
Google: Android 2.1 Downgrades Image Quality
And clearly, Android 2.3.6 still has a 16bit gallery.
At least we know it is not due to the display.

Mine also shows upto 4 on the default gallery and upto 1 using the stock browser, but with the stock browser the greys seem to be reddish.
What I noticed though is that my screen does not have really deep blacks, I can see it as a lit black like and LCD.. not major deal breaker or anything but wish I got one of those screens with deeper blacks. Also I see some speckles of darker area's when displaying the all black screen test.

nexus 7 screen colors

Loving the nexus 7 however I'm wondering is it me or does the screen overall color seem a little faded/washed out. I mean the images are crisp but it seems the color isn't very vibrant.. thoughts? Or do I have a bad unit?
Thanks so much

I found myself thinking the same thing. However the only comparison I have is the same background on my Galaxy Nexus. It could just be the GN being very saturated. I like that though and was a bit disappointed by the screen.

I find the screen to be great. However, I have an Evo LTE so the color saturation seems to be pretty similar.

The screen is great to me. Very clean and viewing angles are great.

Washed after update
The colors were fine, but I'm noticing that they appear washed out since the most recent update. I don't have a direct frame of reference since I updated, but I could swear that the colors aren't as vibrant as they were before. I also have an Evo 4G LTE and the N7 colors are less vibrant (something that wasn't too obvious before). I know they are different screens, it's just something that didn't bug me before.

Hi, could you please comment on how good is skin tone color reproduction. Thanks.

i thinked the same that the colors looks like a bit washed out / fade.. is this normal?
The colors on the S3 are vividly colored

I agree. I think the default automatic brightness feature is a little dull. You should try to manually increase the brightness....that seemed to fix my problem.

Compared to both my Galaxy Tab (original 7" 2010 model) and my Galaxy Tab 8.9 LTE, (both with PLS, Samsung's version of IPS screens), the Nexus 7 is indeed more washed out/dimmer. It's brighter than my Nook Color though.
But the colors are fairly accurate and the viewing angles are good. Hoping for a mod that increases auto-brightness levels a few notches, and a mod to adjust color temps/saturation and I'd be happy with it.
You reading this Supercurio?

Color Banding

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.

Possible Display Calibration Correction?

"Many of the images were noticeably washed out -- they looked like over exposed photographs with missing highlights, reduced image contrast, and weak colors," Soneira wrote.
But I was curious why these shortcomings weren't showing up in reviews -- and why Soneira seemed to be contradicting himself when he told me that the display itself was "high quality." So, I asked him to clarify this.
Here's what he said.
The LCD panel itself is excellent. Good luminance, high Contrast Ratio, excellent Color Gamut and Color Saturation. So the raw LCD display itself is great. The problem is that the factory calibration of the display parameters (generally performed via firmware) is way off (particularly the Intensity Scale) so the images that appear on this fine LCD display look washed out...the display produces washed out images and colors in spite of the fact that it has a display with excellent color saturation and contrast. Similarly, a great camera will take poor quality photos if it isn't properly factory calibrated.
He expands on particulars in the blog post.
There is about a 25 percent compression of bright image content, which is quite substantial. This holds for both the Gallery Viewer and the Chrome Browser. On some cheap displays this is done intentionally by the manufacturer because the compression actually makes them appear artificially bright. Here I think it's probably just incompetence by the manufacturer, which is too bad because they messed up a really nice display.

I also want to know about this. The contrast seems very low to me. This display can do better than what it's currently set at.

Wrong thread ?

I have some faith that when morfic makes a trinity kernel for the n7 that some of this will be rectified. Unfortunately, his order was held up. I guess the first step is to find out what code is tweak able in the kernel to actually do this.

I believe I saw a mod which corrected some of the Galaxy Nexus dislpay shortcomings by calibrating it a bit differently. I wonder if the same could be said for the Nexus 7. @piam, I don't know why the reviewers never mentioned this in their reviews, but that's the first thing I noticed when I opened up my Nexus 7, and that was on the stock wallpaper that was on.
I just hope that someone gets a mod out soon, cause its a really great tablet looking cheap just because of the washed out colours.

I find that the home screen is not well optimized but Netflix is looking pretty good. I also find that lowering the brightness helps...which does indicate a calibration issue.
Its pretty good already though...almost quibbling.

I've noticed while using YouTube as well. If play videos on my Galaxy Nexus side by side with my Nexus 7, the colors look washed out. Probably there will be a kernel fix.

Hopefully software can fix it, if it's a firmware problem.

Anybody knows about today status ?
We need official or not official update for our nexus 7 device!
Asus must give us possibilities for change white color compession!!!
