check out this thread and compare if your XDA II has a yellowish screen

This sounds panfuly familiar. It was along thread of discussions about ipaq 1940 verus 1920 screen. I have also noticed that usually first batches of the new PDA's have better screen the next ones. The same thing was with Sony NR70. Fisrt unit I got wa perfectly white, replacement one was yellow. So, that's I am trying to get a first batch of the new PDA's ASAP.
I just got a replacement for it
now back to the bright white screen by Sony
SGS screen is awesome, even if colors are not really well calibrated...
Yesterday, I saw a recent Galaxy S and it was really brighter than mine (4 months year old)
I noticed a huge difference!
Did anyone of you got the same experience?

Insulting question perhaps, but did you check the brightness slider of both phones?

Of course, I wouldn't have started a thread! lol
Same rom, same kernel, same phone, same country, same settings. I'll try to post some pictures

We just got 4 at work. The supplier told us they only had 1 left a few weeks ago and we had to wait until they got new stock so when they turned up we had one from an old batch and three newer ones. The one older one was very noticably darker then the 3 newer ones even with exactly the same screen settings. It also had a slight blue tint to it.
My brother and I both have I9000 Galaxy. The 1st phone (the older one) was very bright that it resulted in eye strain while using!
After about a month when I bought a new Galaxy S it was very dark compared to the older phone on same settings and same firmware.
So maybe its the issue with some phones or I am guessing that the older phone suffered from backlight bleeding! But now the screen broke and I bought a replacement screen from ebay.
Oled screens don't have a backlight

they dont need a backlight to be viewable.....but SGS still has a backlight to boost the total brightness

Now THAT explains something. I have a pixel tester and when I set it to black, in a pitch black room I can still see the screen. Well now I know... You sure about that though? Even the Samsung Super AMOLED videos make a point of there being no backlight.
AMOLED does die over time, blue first. So as I understand it most of these AMOLED screens in phones have twice the blue pixels to make up for it over time. I would of suspected that the lifetime is a few years though, not months.
There is no backlight in S-AMOLED displays.

As you can see, there is no lamp, neither a white background needed for the light to reflect.

Thought so. So, can anyone explain to me why I can see my screen in the dark when the phone is showing only a black screen? Such as with the dead pixel checking app I used? Perhaps it does not correctly request true black but even noLED from these forums does it.
I would expect it's due to leakage current.
Each pixel on the screen is controlled by a transistor (actually probably more than one). Even when the transistor is turned off (and the pixel should be dark) there will still be a small amount of current leak through. I suspect that this is what causes the screen to glow slightly even when displaying black.
Of course when the entire screen is turned off, no power is going to the display, so even this small current stops and the screen is darker.
Maybe Samsung has switched to SLCD screens.
The rumour circulated few months ago that Samsung has stopped the production of the Wave and the Galaxy S smartphones because of the Super AMOLED shortage.
Maybe now they are shiping SGS with SLCD.
The SLCD screens are much brigther than SAMOLED.
Here is the comparison:

I highly doubt samsung would discontinue the SGS line for any reason. In fact, they just started to showcase the 7inch SAMOLED most likely for the next gen galaxy tab.
However, here's a comparison.

I'm sure it was an AMOLED Screen, easy to recognize...
I'll try to make some photos.
i got mine when it first came out and i have it on zero brightness setting and it is bright and clear (except in sunlight when it becomes as hard as any other phone to see)
ive tried about 15 of these phones and the screens on all of them were different when set to the highest brightness. The most common differences were darker and lighter shades of blue. a couple were more red than others and looked 'warmer'. The one im using right now is pretty neutral though not sure why that is but they all seem to be different.
(all 15 were running JH2 stock with no lagfixes on i9000m from bell)
Argh...
I have a dead green pixel towards the bottom of the phone... And now that i know its there.. I keep looking at it! Def wasnt dead when i got it
A good way to test the pixels is via the *#0*# menu... red, green and blue.
i always have brightness settings at the lowest and when i was using eclair rom everything was really dark. after flashing froyo rom i noticed straight away even at the lowest settings the phone is still pretty bright but green colour does not look good at all.
Just got a replacement tab 10.1 from Amazon to replace one with at least 3 stuck pixels & I'm seeing that this new one is warmer then the stuck pixel one which is on the cool side. Is this likely a physical difference in the panels or a software adjustment? Will we be able to eventually adjust colors like on a PC? Which color temp would you guys prefer?
I mainly exchanged for the pixels, but I also notice some dots of dust which I'm just gonna put out of mind. I'm guessing these aren't assembled in clean rooms. Have a Transformer to be returned that has it worse with what looks like a speck of lint.
I'm using mine as a portfolio and calibrated colors / neutral would be best. I have noticed that colors are more saturated with the tab and a little colder compared to the iPad.
I also found dust on my screen and it bugs me. I'm geting a replacement at Best Buy.

Hello,
I went from a Note 2, to an Xperia Z and now I am considering the S4.
A few questions:
1) The whites on the Note 2 were yellowish. How are the whites on the S4 compared to previous gen devices?
2) There were black splotches on the amoled screen of the note 2, which I noticed when the screen is displaying a black image in a completely dark room. I noticed that this was normal for amoled screens. How is it on the S4?
3) How is the Bluetooth audio quality compared to the note 2 (The note 2 uses a Wolfson audio chip)

1, I too have used note 2 white and it gets little yellow after few days
but in S4 its better then that as it has a different texture on the back panel which looks good and does not loose its whiteness
2, There are no issues with the screen its immaculate u ll love using over N2 for sure
3, Bluetooth i havenot used so cant say however S4 has better audio chip
saw the tweet from supercurio. Wm5102 on 9500 has a very powerful Headphone amplifier

Thank you for answering. Good to know
However, for number 1, I meant the whites on the screen not the body
How does the display, display white colored images? Are the whites, white, or greyish, or yellowish?

Yes its white no plm with that too
Looking to buy my first tablet, I love the Amelod of the Note 2 and absolutely hate LCD on phones because the colour is so bad.
Is this tablet amelod or lcd?

It's LCD, but the screen is the best on the market compared to others.
It's an extremely nice lcd. If you want amoled go for the tab s. No digitizer though so it's pen vs screen decision time. Base hw is basically the same.
The next version of 10 incher Samsung Note Series may use SuperAMOLED screen again. :silly:
But I see some battery test of Tab S compare to Note 2014,Note Pro , SuperAMOLED consume more battery than LCD.

Considerably more battery, but blacks and dark colors so have more saturation...But is it worth it? I say no.

I always thought that LCD use up more battery because they have a backlight illumination.
Since Amoled pixels emit light, they will use nothing to display black. So great contrast and low power on dark pages, screens, movies etc
Lcd will use similar power to display any colour as the pixels block or allow light to pass through from a backlight.
Lcd will use less for very light scenes, Web browsing and with less contrast
Its a choice...
