can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.
I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.
This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

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.

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.

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.
Dear owner of galaxy s2,
I'm sure I'm not the only to be bothered by the screen color temperatures totally wrong. Mine tints really to much to blue.
Did someone manage to install a screen color changer ?
Thanks
I think its being worked on. Meanwhile if you go into the screen settings you'll see a setting for display type or something similar. Switch that from Dynamic to Movie and the colours should be more balanced..
It should fix itself over a few weeks, the blue amoleds degrade a lot faster than the green and red
So in a few weeks it degrades faster, does that mean in a few months it would've degraded so much he'll have another issue? I don't think your comment makes sense

I have bought my 2nd sgs2 yesterday and I found out that this unit has lot of red tint in low brightness. Almost the effect is so high that all those gray bands look like light maroon shades. Samsung has really messed up with these samoledplus displays in sgs2. In my 1st sgs2 the display was quite dull even in 100% brightness compared to other sgs2 displays. Fortunately it was gifted to me so I sold that unit.
But this new unit has new display problem of strong red tint all over the screen affecting gray shade a lot in low brightness mode. The only fortunate thing is that famous yellow tint issue is almost nil and in 100% brightness display is very bright. But I am still gonna ask for brand new replacement of this faulty sgs2 unit.

I have only seen 4 galaxy tab 7.7's so far and I noticed all 4 of them really have bad white levels as compared to my galaxy note, disabled the auto power saving and there is a difference in white levels but its still not even close to the galaxy note at the same brightness level. Even at brightness 25% on the note the vs 100% on the tab 7.7shows 'dimmer'whites. This is not a rant but I'm just asking if the screens are calibrated that way or should I keep looking?
Also I noticed that the mdine engine oon the tab provides oversharpening to a lot of my photos and its so obvious and makes the images look bd, supercurio has the same findings.
It is a pretty big screen so it may be they limited the brightnes to save battery power. While the claim is that OLED takes less power than LCD that is not always true. When displaying white, OLED tech uses like 4X as much power as LCD. The power saving comes in when displaying images with medium to darker colors.
What is the "mdine engine"? Is this something that can be bypassed by using a different picture viewing app?
It is amazing how Samsung seems to always add some crappy image "enhancement" like DnIE or such crap. Why can't they just leave our images alone, as we meant them to be? It is freakin' OLED man. You don't need any contrast or sharpness enhancement you knuckleheads! OLED by nature is sharp and has great contrast! Duh!
I don't know. My 7.7 is super bright, sharp and with way warmer colors than my Note.

I'm thinking the samr thing that samsung might ne limiting how bright the whites can go duebto the screen size but based on what I've seen on samoleds some screens juat put out better white levels, not really brighter but whiter.
For the mdine its running system wide.

The samoled plus tends to have more warmer colors than the samoled, is the whites on your tab 7.7 'whiter' than on the note at the same brightness level?

Yes I believe so, Supercurio knows more about that stuff.
EDIT:
simulated example done in photoshop, anyone with the tab7.7 and better photoshop skills feel free to redo this simulated image
Perhaps one of the other reason that the 7.7's screen isn't quite as bright, apart from the obvious power saving reasons, is an effort to possibly reduce the OLED degradation (burn-in) effect.
Either way, although I certainly noticed out of the box that my 7.7 wasn't as bright as my Note (or even my GS2 for that matter!), I was never really bothered by it because (especially when you use movie mode) the colour reproduction is very accurate, and paired up with the contrast levels, it's still fantastic!
I guess, to me, white doesn't necessarily mean I need to put on a pair of sunglasses while looking at my screen lol!
I just wanted to know if the norm has lower white levels, what bothers me more is added sharpening on some images.

Yellowish? Not at all! At least not with my unit anyway. Sure it makes the screen generally warmer in colour, but IMO, more than anything, it makes the colours look more accurate and natural.

Well ever since the Galaxy S changing the color mode to movie mode gives a yellowish cast, this is probably dependent on the calibration on the screen we get in the first place. I saw a friend's Tab7.7 the other day and his white levels were really brighter than my Galaxy Note. FWIW, its still a luck of the draw when it comes to color calibration on the screen. But thanks for that tip, when I'll purchase the Tab I'll make sure to also check out movie mode and see if it hits my requirements.

Very bright noticed the same with the Note ,
Nexus was somewhat easier on the eyes at night,
But probably like you I like a very dim screen at night.
When the brightness is turned all the way down on the 7.7,
is any banding or other issues seen like many report on the Note?
Blacks are black I'm sure but how are greys that are near black.
On the Nexus they were fine, but on the Notes I seen they could have been darker?

What is the other phone? Go to settings -> display -> color mode and set color to normal, that will normalize it a little. It's set on vibrant by default. Regardless of that setting though, the screen on this phone is a "warm" one compared to others. The phone on the left is "cold" and bluish in comparison. Warm screens are a little more yellow/red, cold are blue. If the other phone is AMOLED there's your reason, but even if it's LCD, it's just tuned a bit differently. You should know that the phone on the left isn't producing a perfect white either, just a kind of white you're used to. Personally I prefer a warm screen, I find colder screens harder on my eyes.
TLDR- it's working as intended.
Unless you screwed with some settings no that isn't normal. If my whites were that yellow I'd return it. While an LCD might never be as white or black as an amoled it shouldn't look like 20 year old yellow paper either. WIth LCDs if you lower the brightness the screen will become more colored but nothing like that. You can also go compare it to some phones at the store that have LCD's and get an idea if its out of whack.
I spoke to two different support people at motorola ...one said it was normal for this phone as the screen was optimized for gaming?? .....the other said it was not normal and I should return it.
I tried using the app 'screen adjuster' to boost the blue light and it did indeed make it look white rather than yellow so it seems to be a color temperature setting so I'm still not sure wether changing the phone would make any difference and I can't compare in stores because they don't have them yet.
p.s. the other phone is an LG G2 which is LCD
Mine seems to have a little yellow at low screen brightness but it doesn't seem as bad as in your photo. I probably would not have noticed if not for this thread. Is your screen brightness low? Mine gets more white as the brightness goes up.

If it bothers you you can go through the return process and see if another one is different. My phone looks pretty much the same next to my Galaxy Note n-7000. That's AMOLED, but AMOLED or not, screens can be bluish. For perspective, here's what white looks like for reference. Neither of the phones are producing white. One is bluish, one is yellowish. Do you notice it when you're not comparing phone screens? After a few minutes of looking at the screen, going from app to app or looking at pictures, do white things register as white?
