Hello fellow s4 users I recently installed the display tester app from the market and went into the testing area and chose the gamma test. The first color is gray and it seems to go from a pinkish white too dark grey on the first screen of the test. If anyone doesn't mind installing the same app and seeing if the whites display white or are they displaying light pink I want to know to see if I have a bad screen. I I tested on a note two and a cheap LG phone and they both display colors way better than my s4. I haven't been able to test another s4 therefore I want to see if someone can shed some light. Thanks.

Tbh, All SAMOLED screens have this effect at least my old captivate did.
Wait until supercurio messes with our phones He fixed that issue for me on the Captivate. I'm pretty sure he's going to able to work his magic on our phones as well.

Turn off autobrightness and set it to 40% and it should be less obvious.
yup it's a common side effect of all the SAMOLED displays
it's less obvious when you have the brightness at around 30%
the only phone that doesnt is the nexus s.. because google made the color a little yellowish in an update. Maybe its the rom, or maybe i dont notice it anymore, but beastmod v3.6 seems to have white whites
Welcome to the club.
That's why we have this: http://forum.xda-developers.com/showthread.php?t=1345099
I apologize if my attempt at search terms didn't yet yield an answer that has already been posted.
On my Droid Charge if I tilted the phone up or down in portrait mode it would cause the screen to take on a blue hue. It turns out it was because of the screen protector I was using. Took it off, no problem.
However, I have no screen protector on my Galaxy Nexus, and I'm seeing the same thing occur. Since the screens are hardly the same (AMOLED+ vs AMOLED, different resolution, different size) I can't really tell if its normal. The demo model at my store was out of commission.
Anybody else notice this or is there something wrong with my screen? My friend said his doesn't do it, but I haven't seen it myself (he lives an hour away) and its possible he just isn't as picky as me
Thanks in advance.
I got the same thing on mines. Blue tint when not looking at screen straight.

when my buddy first got the Samsung Facinate, I remember noticing that weird blue tint. maybe it's a Samsung thing?
Voodoo color should come soon to fix that!

A blue tint of some sort, or cool colors in general are a product of the Super AMOLED screens, yes.
I don't think Voodoo Color would fix it in this respect, because I think it either has to do with the coating on the screen itself, or the way the light is refracting based on viewing angle.
I could be wrong...
On my Galaxy Note 2, if I display a pure black screen in a completely dark room, I can see that first of all, the "black" is not really black, but somewhat pinkish. And second of all, there are "really black" dots and lines across what is supposed to be "pure black" but is somewhat pinkish (like i said). Also, this effect, of having a darker line, can also been seen with say, dark blue on screen in a completely dark room.
This effect is not noticeable when white or other colours are on screen. I'm really sorry but I can't show you a picture of this because obviously a screenshot captures the digital signal and not the physical output and I don't have a good enough camera to take pictures of what I'm saying in complete darkness.
Is this a defect or just an unavoidable "feature" of Samung AMOLED screens?
you did not use the search function: i personally wrote a huge amount of posts regarding this, also in the note1 section!
search for "black blotches" or take a look at my posts. really lots of them are about this!
in short:
its manufacturing dependant and its luck of the draw to get a "good" screen!
samsung lives with this as not many customers complain(ed) about it, as most of them do not even notice it!

Mine is pure back at full brightness when seen in a dark room (no pinkish hue or any line that you mention). And Note 2 screen doesn't even have the infamous black clipping/crushing issue like its predecessors! Blue colour also good, no issues for me.
No, it is definitely not an AMOLED feature or drawback (never seen it on any other AMOLEDs either)! Of all other aspects samsung SAMOLED screens are known to have the deepest blacks (with best contrast ratio). Sure, it sounds like you have a defective screen, and my suggestion would be to get it checked up at SC for replacement.
i also have a similar issue on my note 2. a black screen is not completely black, but a brownish black. And i can see 3 (or more) dots which are completely black.. i can see this only in a dark room, so normally this is not an issue. But when i read kindle in my bed with dark background, this really bothers me. initially i thought this was some smudge on the screen. im sad to hear that other people are also having this issue..
I had the black dots on my galaxy s2 ... but not my note ... The screen on my note has none of that sooooooo happy about that it really is just luck of the draw ....

Same issue here. But it does not bother me that much, and if I get it replaced, the next one might have worse issues.

im only worried if it will grow in time. like a dead pixel in an LCD screen, if this phenomenon spreads to the neighboring pixels over time, then its a very bad thing... otherwise, i am not bothered at all..
We need this thread each time there is a new phone which amoled screen? ..
The sgs2 has this as well as the sgs3 the note 1 etc.
it's not a defect, it's a limitation of amoled screen production.

Sorry, what you say here its not possible! EVERY amoled 'suffers' from this ('cause it CANNOT display 100% blacks, due to it's active matrix)! If you won't see it it's because of a wrong method or your eyes!

Coming from a galaxy s2 which had pure blacks. If I looked at a black image in a pitch black room I almost could not tell it was on. Was very feint light output.
On my new note,
While having a beautiful display, given the same setup the blacks are not as black. The screen is brighter. Is that a defect?
Also noticed some areas weer a bit darker like blotches. For most uses this is not noticeable but when I read in the dark and use night mode along with a screen dining app to get it really dark, the background looks more dark brown then black

Coming from an S2 Skyrocket (LTE) which had horrible blacks and really bad splotches/blobs my note2 has much better blacks and no splotches that I've noticed and I have looked for them. I havent brought out the magnifying glass though..
i can clearly see that the white of this phone is much much more warm and yellowish respecting others phones with lcf, but also a galaxy note 4 ( amoled) of one of my friends.
i can't understand why lenovo made this calibration. Of course maybe using it as primary phone you will not notice it after some days, but at the moment it is my secondary phone and every time i switch from lcd to p2's amoled i can clearly see that the white ruins all the colors....into an image.
ps: maybe OVER 50% of brightness the white starts to be "ok..." but under 50... 40% it is not a nice white

but does it interfere with the PURE BLACK? i noticed that there are apps that can "fix" the temperature of the color by adding a LAYER on the screen....
but this layer corrupts the true black.... no more really black but with a tint of blue or yellow ( blue if you try to make colder, yellof if warmer)
i hope you made a real test about it, use the app https://play.google.com/store/apps/details?id=com.gombosdev.displaytester and visualize the BLACK color.
if it is not 100% off the display..... the live display option of your rom is not acceptable

Nup,,black are true blacks(pure black pixels get off),,almoled display does not have pure white they are warm(yellowish)i had set it to cool color (blue)which makes the screen look little white than yellow,,i will compare display with samsung device and check,,buh black are still pure black no yellowish or white tint on black
Sorry for bad English
Sent from my Lenovo P2 using XDA Labs
but did u test? because some tricks to change the temperature of the displays.... are to add a "layer" of color.... and this makes NO MORE TRUE BLACKS on amoled diplays....
Yes,there is noticable difference in white the stock ROM now looks a little yellow but the stock deodexed version has the cool white colour which looks far more beeter that yellowish tint
I have not so idea for the reason behind that may be Lenovo has recalibrated the screen if you want to change the tint you can try various apps that requires root to calibrate screen Colors manually
i found the problem !!!
go in the live display and at the colour calibration menu.
JUST set the green color to 92% and the white will be PERFECT
i noticed tha tis ONLY THE GREEN that destroys the white.... just lowering it to 95 gives a normal warmish white... setting to 90 it is like a normal lcd cold white ... at 92 it is perfect between a warm and cold yellow, the perfect sweet spot.
now i am FINALLY HAPPY with my screen.... and the white written on all the app themed with black substratum, are finally well constrasted with the black..... being pure white
