Weird pattern grid

I honestly dont know where to post this as is there are many galaxy s forms. Anyway
I see weird pattern or grid if i turn the brightness to the lowest and i have dark gray wallpaper. Anyway its more visible in some area on the screen more than others. Is this normal? what is it?

i have a fairly good idea the grid you are referring to
there have been posting of this before in the forum
some people have dismantled the phone and shown the pictures from the inside
in most units you shouldn't see it at all
if you do it was probably not manufactured well, you are not supposed to be able to see it.
I'll return it for an exchange.

Like i said its very hard to see. And its not like u can go to the store and turn off the lights to show him something he probably wont see

Yup, I see the same thing on mine (using voodoo lag fix on lowest brightness). I can also see it on my GF's galaxy and my coworkers galaxy as well, but very very faintly as they're not running voodoo so the lowest brightness is not very low
Most visible in dark gray. Doesn't really bother me that much as the screen is otherwise great
I sure hope we don't all have defective phones? I'm guessing it's an inherent issue in SAMOLED?

To be honest also my brother has it in his phone. But mine is way much less. And I decided to buy galaxy over hd2 because I like the super amoled screen and better gpu over the desire hd. just wanted to ask about the screen

That big square? All Galaxy S phones have it. It's the motherboard or something. Don't worry about it. It's invisible in any normal situation anyway.

color issue?

is it just my phone or what here?
I have noticed the saturation of colors on my atrix are just horrible specially green which makes yellow and orange that's why yellow and orange are really off... just me or everyone? if so anyone got an idea on how to tackle this issue?

search is your friend, its not just your phone. Its also not really a problem for a lot of people, myself included, since id take it over supersaturated colors any day.

The Colors on my phone look like the colors on my Touch Pro. What I mean is that they look the way they should.

Agreed, mine looks fine to my eyes. Best looking screen I've ever had on a device besides my G73JW.

I cannot complain. My color look ok to me.

The resolution is amazing I can't lie but the quality and the color are **** compared to my amoled desire.. green is too dark and the quality of the picture is wack too pixelated...

everyone who says it's not important is lying at least a little. the screen is not perfect, period. one needs only to look at a green image or moving red image to see the flaws in the screen design.

As a color blind person I can say that the greens look fine to me. and thanks for saying I am lying even if only a little.

There have been a couple of colour comparisons, and I believe the concensus has been that the Atrix has more "realistic" colours, while we are more used to other devices having colours that "pop" with over saturation. We have become accustomed to over saturation, and so when we see colours on a screen that more closely match real world colours, we think there is something wrong. I will take the Atrix colours over anything else I have used.
<edit> I have seen one comparison where correct colour calibration techniques were used to compare the Atrix to I believe the iPhone4. I will try to find it again and post a link.

[Q]Whitelevels and screen sharpness

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.

I havent but id imagine thats gonna give a yellowish cast on the entire screen. I didnt get the tab yet as the store units I tried had very obvious screen problems. Gonna wait for a the next batch to arrive.

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.
Give it a try! You never know until you do...

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?

Screen Mode is a JOKE

i am wondering what Samsung was thinking
when made of this.
Natural mode has washed out colors and normal mode
has over saturated colors .
We need something between.Is that so difficult?

ur thead is a joke

There are no oversaturated colors
All AMOLEDs are like this and I think display is very good.

Natural mode is pretty much perfect imo.

Totally disagree, natural looks washed out and very dull. My iPad 3 and Galaxy Nexus is much more vibrant.
To me standard, looks fine. Just a touch too over staturated but I like it, like that.

great joke im laughing

Coming from an WVGA TFT LCD on the HD2, the Natural Mode on the SGS3 seems to highlight the best of both worlds.

You are correct. Earlier today I was messing around with Screen Adjuster and it was skewing my side-by-side iPad / GS3 tests. I've edit my original post.

Standard mode is over saturated especially in games
and when browsing.
An extra mode between standard and natural would be
ideal for 99% of people.

They should just release all phones with a screen calibration mode after the first boot up.
People fail to realize that humans only see about 10 million colours so that the 16 million available, regardless of screen technology, is all there natural or not. There could be a variety of factors that contribute to AMOLED looking less natural but if I were to hazard a guess.
- people are used to seeing LCD looking colours.
- the LEDS are closer to the screen on AMOLED.
- Complete blacks trick our eyes into seeing colours around the black abyss as being brighter than they really are.
And of course the obvious such as a coloured organic Light source vs a white light source plus colour filter. And also the backlight needed on LCDs.
I think consumers just have to be desensitized to AMOLED displays and it will start to look natural. Or Samsung should do a better job with the natural mode and mimic LCD better. Or they should just give free reign of colour calibration like they do on HDTVs and add a back light. So if you like AMOLED, turn off the backlight. If you don't, leave it on. Barring the texture of the LCD colour filter, an AMOLED display with a backlight would look just like an IPS LCD display.

You know what is a joke? All the US versions don't even have a screen mode option. Oversaturation is nothing new for AMOLEDs but it can be remedied and has been remedied before, simply by providing an option. A lot of people like the contrast and viewing angles of AMOLEDs but don't like the excessive colors. I guess Samsung thinks Americans are all colorblind and took the extra effort to REMOVE the option altogether when they tried so hard to make everything else the same. The international S2 had color adjustments too, but not my T-mobile one. Then there's the terrible audio capture. Always taking two steps forward, one step back.

I quite like having an option to change my screen settings rather than not having an option. Thank you Samsung.

I agree as well that screen modes could be better "optimised" that sammy would give us something between natural and standard, but different to you i am feeling that was step in right direction, im sure that next phone will have those much better optimised.

Due to the chipsets. Samsung used the television engine. The screen modes on my international SGS3 is the same ones as on my TV, producing nearly same effects (TV=LCD, SGS3=AMOLED). Sony uses their Bravia engine in their phones.

Hey guys, you do realise people are entitled to an opinion, right? Stop dismissing the OP blindly.
I happen to agree that the default profiles are not as good as they could be. Simply accepting that AMOLED is oversaturated by nature doesn't mean something can't be done about it in software. So before jumping down someone's throat, perhaps consider that they may have a legitimate concern.

proving Oled (amoled brand name) superior unlike what your told by mainstream media!

Your told, lcd is brighter in sunlight which is the main reason your tokd Lcd is superior or at least thay say amoled is inferior. Wrong,its because if default settings by the makers. Once rooted with proper kernel(almost every device has em) you can do with amoled what you cant do with lcd. Double the color multipliers from android default of 200 to 400. I use in order of RGB, 320/320/400 to achieve perfect white and black. Also the battery myth,lcd drains less. Thats bullcrap. Amiled black pixel achives pure black because its actually OFF. that is main reason it uses less power than lcd. Instead if going on and on I will just show u proof. I will show you picture of my LGOG(sprint optimus g) and my even aging gnex side by side in sunlight with my shadow on half the screens to show its actual sunny lol. A pic says a lot more than my Bloveating. Im using my sgs4 to post this and used its awesome camera tontake the pic if pic does not show in op I will post in first post. Have a great day peeps.

Pics wouldn't attach.must be because of using phone

Pic

2 different pic styles,img and jpeg clearly shows that even with a shattered and pentile matrix amoled screen its brighter in the sunlight. Even did my shadow in it so no one would say....sun wasnt out lmao. Sorry naysayers proof is in the pudding and the gooey pudding is right in front of your face. Proper kernel with amoled is brighter and better battery saver than lcd. Lcd is backlit anyway and most high end phones will use it in the future because it can be bended and manipulated and LCD can't because it is backlit. Only low end phones will be lcd in the future.

I agree with what you've said (I use Samsung phones primarily), but it is true that when displaying white, it uses 3x as much power as an LCD. On mostly black, you're correct; very little power draw.

Tell me about AMOLED burn-in. Since you are increasing the luminosity, I would suspect that burn-in would be faster?

Keeping my eye out for this one...very interesting.
Do you guys mind if I ask what this "burn-in" is and how to fo about it?

Similar to plasma screen televisions, if you leave an image on the screen for a long time (much more than average), you'll see remnants of it permanently. However, if it's anything like televisions, you can fix it by displaying a white image on the screen (entirely white) for a few hours. I've never had this happen to me and ive owned almost all major Samsung phones. Nexus S, Galaxy Nexus, Galaxy S II, Galaxy S III, Note 2, and now S4.

Yes burn in can occur on older like the gnex. Newer amoled is less likely but always set time out of 2 min when color multipliers are set to max. Best settings,for pure white is ,320,320,400 rgb color multipliers. Sorry should have talked about burn in,my apologies .
