Yellowish screen galaxy s7 - Samsung Galaxy S7 Questions and Answers

I got my S7 today, the first thing I noticed is that the whites looked quite dull and uneven on the display, for example when browsing and scrolling up and down I'd notice the uneven white background, one side is brighter than the other.
This has always been the case for me on just about every samsung amoled I've had and it's always taken replacements to get a display I like.
I went into a store today and compared my S7's to the ones they had on display, I made sure to set the stores s7 to the same brightness as mine and making sure the phone was on adaptive mode and the stores s7 just looked so much better than mine, their was a blue hue but it made the whites brighter and more even
Has anyone had screen issues like this with their s7? Should I get a replacement? Even my old phone which isn't amoled has much brighter whites than the S7

can't explain any kind of gradient from one side to the other, but there is a setting on the S7 "Screen Mode" under the Display and Wallpaper menu gives you 4 different settings some of which will give a more yellowish hue as opposed to the blueish hue normally seen in modern displays.

On my S7, I sometimes notice the white background in Chrome browser to appear a bit yellowish. I didn't notice it any other app or maybe no other app had a significant white background. If I tilt the phone just a bit to thereby change the lighting, the yellow hue goes away and it appears white like it should. If I don't tilt and keep scrolling, the yellowish hue also turns white.
Sometimes, I've noticed it while using FlipBoard as well.
Since changing the angle fixes it, I presume it is software-related and have not considered replacement. To me, it didn't sound like a hardware fault.
If it appears in other apps or fixes altogether somehow, will post again.

Under Screen Mode, I have 'Adaptive display' selected. I see a note at the top stating 'This mode may not be compatible with third-party apps'.
Since it only occurs in Chrome and sometimes Flipboard, perhaps some third-party apps just don't play well with Adaptive display.
Switching to AMODEL photo changed the screen to the similar yellowish hue...! Anyway, I'm keeping mine at Adaptive display.
Hope the OP's issue is also limited to certain apps.

Hii.. go to settings then display and turn of blue light filter...
Have fun with ur fone.

Do you have screen protector on? I found mine was not "very white" or yellow ish compared to other, because of my screen protector.

Note3 AMOLED Screen Quality *edit: tested 6 devices so far*

hi,
i just started this thread to get your opinions regarding the display quality of the note3!
i have to admit upfront that i'm a hypocrite when it comes to amoled screens, so far i had to switch all of my amoled devices a least 5 times until i got a unit which satisfied me. done this with the first note, and also with the second.
as far as i can say the screen of the note3 is the best i've ever seen (by far better black-levels as note1 and note2), although i also identified a few flaws as well:
the color RED has very bad viewing angles: when tilting the device a little bit the color gets orange immediately.
try this by enter *#0*# in the dialer, and click on "red" then tilt the device. let us know how "your red" is, thx!
the gamma of the screen is totally screwed: can see down to "1" in gammatest.png:
the disadvantage of this is that you are actually able to see dark grey screens which you should not.
on the left side of the screen border there is a small strip which has also more gamma then the rest of the screen, in menus etc.
this is clearly visible when its dark around. also only visible when at least a little grey is to display, pure black is ok!
this week i will test one or two more note3's, just to have a comparison and to determine if the quality spread is as big as with previous devices. for note1 and note2 the differences between devices were really huge. some screens were near to perfect, most of them had flaws with color unevenness.
what are your impressions?
and: do you care?
regards,
markus
edit 03.10.2013:
just got my second note (this time from amazon.de): the screen is considerably better!! the "more gamma" strip on the left side is non existent on the second device, in gammatest.png the screen is much more uniform! also the red viewing angle is better, it still fades to orange when tilted, but not as much as with my first device!
conclusio: the big differences in screen quality are still existant, it's still luck of the draw if you get a decent one or not...
also the general build quality differs: on the second device the pcb is not exactly in the middle of the casing, the camera hole is not centered in it's protrusion, and the power button extends a little more out of the casing.
again, i may be a "little" freaky about this things, but for > €700 I want to have a decent device!
screen quality is very important for me, because i read a lot with the device, especially in dark environments where the left gamma strip i mentioned was really annoying! i also showed this to a few colleagues of mine, and they agreed.
edit 04.10.2013:
another finding: when CPU load is high, the brightness jumps between a lower (darker) and a higher (brighter) state, even if brightness is set to manual: both devices show this behavior, although not exactly identically: my first device needs more load to start with this (it takes longer), the second one starts the dimming relatively early.
how to test: load a stress test tool (cpu prime benchmark from google play) and let it run, set the brightness to manual maximum and wait.
you will see that after a few seconds the screen will go darker, and will switch between this states. this is independent from the brightness level, it is only better seen at maximum!
i guess this is some power and/or thermal limitation (when more cores are under heavy load), it would be interesting how this kicks in in summer when ambient temperatures are higher...
edit 25.10.2013:
just to let you know: i'm now through 6 devices, all of them had display flaws in terms of uneveness.
a issue most of the devices suffer is the lower dark half of the screen: on 4 of my 6 note3's the lower half of the screen has been signifcantly darker then t´he upper half,
one had a very bad gamme increase on the left 2mm, one had a bad gamma increase on the top 2cm. 4 had a warmer white, two of them were more cold (more blue). could be due to missing or wrong factory calibration...
what is gone is the "blotch issue" i had with sgs2, note1 and note2, and: black is now really black!
but on dark grey levels the uneveness is clearly visible, look at the attached "gammatest.png"
this shows the lowest grey tones. and should be a very visible gradient from top to bottom.
go in a totally dark room, open the pic, zoom in max, and navigate to the top left corner. then pull the
picture down, and look how the numbers fade. for example: "6" should be at the same brightness level on top
and bottom of the screen. it definitely is not...
go out and test for yourself, and post your findings!
Hi there, I should be receiving my N3 next Wednesday. Are the blacks the 'true blacks', as in taking the phone in a pitch black room and blacks cannot be seen?

OLED screens are the only ones I know of that can get true black. With OLED the pixels make there own light so no back light is needed, thus black pixels are not being used at all so a black image has a nice inky black color. You notice it the best when you have a colorful picture with black in it.

sorry, but this is a wrong statement. all amoled screens so far were NOT totally black, even if you displayed a totally black image! the reason is that if the screen is active the display controller is powered (which is the case when displaying a black image, and not if the screen is "off") which can be seen as a faint and VERY dark glow. you can only see this when the room in which you are is totally dark, and your eyes had time to accommodate. to make it worse: on all AMOLED devices i've seen so far there were patterns (like hair lines and blotches) in this grey glow, due to the manufacturing technique used (lithography).
see for reference:

and so on...
so the question of cd993 is reasonable!
answer: note3 is the first device where i cannot see this dark glow, even in a total dark room! so a big improvement on this side. not sure what they changed, but the glow is definitely gone!
Red turns orange here to, but it doesent bother me as the screen is nice overall. Much better than my note 2
Red turns orange when screen is tilted, yes. Black are true blacks in Note 3. If you go to a pitch black room, and display a completely black screen in Note3, the phone will blend in and disappear.
Thanks guys, cannot wait to receive my device!!

Please make a quick guide of what to test and what to look for on a new note 3, in order to decide whether or not to return or warranty claim. Basically: On arrival, what would you check for, and what result would make you return it and get a replacement? How much of any issue would be ok for you to keep it..?
N3 screen : brighter and look better than Note 2 and S4 but still can not compare to the best IPS screen about white color

You'll do that with any Android phone whether LCD or AMOLED because their screens aren't individually calibrated (iPhone's are). So there's some degree of acceptable production tolerances that means all built won't be identical. So whatevery you went through before you'll go through again with the N3.
Oled = true black
LCD = true white

Today I got my N3 and all I can say its SUPERB!!! Abs everything
My only concern with AMOLED is the blotches that show on a grey screen in a dark environment like the first time I noticed it using Facebook. I had to replace my first Note II and even the second has some blotches but not quite as big and bad.
I've attached a grey background for your convenience to see if your AMOLED has blotches. You'll need to be in a dark environment like reading at night without the lights on (simulate by going into the bathroom and turning off the light).

Pointing out to OP that the leaking light on the Note 2 (and s3) is extremely reduced in the S4 and Note 3 - you should not compare the Note 3 with the Note 2 in that aspect.
Black wallpaper on n3 = better battery life then?
Other than seeing imperfections in impractical situations, is there anything about the display that is actually bad in normal use? I mean do you see whites on this phone and think, hmm that's more of an off-white or is it like so small in difference that you need a color spectrometer to prove that it's not "true" white?

I know what you mean. I had that on my note 2. Not so on my note 3. When I open black screen in a pitch black room, the phone becomes completely invisible as it blends in perfectly with the dark. And yes, I'm not exaggerating. It's the deepest black I've ever seen on any display, it's like the phone is actually turned off.

Hi Guys!
Need info about PURPLE SEMARING. Does the Note 3 has this issue? Because all the S4 has this semaring issue although it has a pitch black. Please confirm this purple smearing. If it's totally pitch black and without smearing it will be the perfect screen out there
Thanks guys! :highfive:

[Q] At night, black is not black

Got my OnePlus last night and generally I love it. But I have one showstopper that I'm hoping has a fix that I just don't know about. Is there something wrong with my phone, or is there a fix, or is the problem with me that I’ve become perverted by AMOLED?
See, I use my phone to read at night before bed. Lights totally off, and the black background is just not black, it's grey. My last two phones are a Galaxy S4 and Galaxy Nexus, both of which have AMOLED screens. From what I've read, the AMOLED has a very deep black because apparently the lighting is per-pixel, so the pixel is literally not even on when black is on the screen, right?
So when I read at night, the lit pixels are a deep amber orange, and the black pixels are...black. On the OnePlus, the deep amber orange is washed out (comparatively), and the black pixels are...grey. This is pretty much indistinguishable if there's any visible light in the room, but at night with all the lights off, it’s very obvious since I’m used to the AMOLED black. This shows up in both my ebook reader, Moon+, and in Chrome and Gallery when downloading a "pure black" photo. I even use a program, Screen Filter, to dim the screen down below the lowest brightness setting, but the black background is still too bright for me. And yes, it’s there without Screen Filter.
Again from my reading on this, I seem to find that LCD screens (which the OnePlus has) light the whole screen for their backlight, so this may be pretty much inevitable. Is this accurate?
I’d post a photo, but in the kind of low light conditions I’m talking about, no photo would show that kind of contrast. At least no photo I know how to take.
PS - This does not appear to be the "yellow screen" problem I've been reading about. The colors seem consistent from top to bottom. But I'm not very good at color distinguishing.
Any help is appreciated! Thanks!
You're just used to AMOLED displays, the blacks on those are much deeper because it's not actually lighting up when it's displaying black, it's displaying nothing at all. This is because there's no backlight, each pixel is made up of three LED's, so when it's displaying black none of those LED's are firing up. An LCD display is completely different, even when it isn't really displaying anything (black) it's being lit up by the backlight. There's nothing you can do about this.

What he said.... the OP can adjust his screen settings accordingly to emulate a "AMOLED" experience as previous phones such as N4,N5 has done this.

Bad viewing angle on Galaxy S7

Hello everybody.
I received the exynos galaxy S7 few days ago. The experience with it is very good so far but there is an annoying thing about it. As I said in the title, the viewing angle are bad.
Indeed, for example when the background is white (rather yellow even with my display in basic mode), the colors change when I incline the smartphone for example at the beginning the yellow tint (normally white) tends to white then to a chameleon tint ( green, red, blue, purple) tint very fast. I know it can be normal with extreme viewing angles but in my case, it happens when I slightly incline the smartphone but I can still distinguish the content displayed though.
My brother owns a galaxy s7 edge and he doesn't experience this issue.
Do you experience the same problem? Do you think my device is defective?
Thanks.
I,
My device gets blue/green tint when I slightly incline it too... it's my first Samsung and amoled screen, so I don't know if it's ok, but I find it very disturbing...
Get a replacement if you can. I had a blue tint on white at very small angles on my first phone, the second one is better, not perfect but I can live with it.

I had a replacement this week-end and... the problem is still there !
Ok, I admit that it is less "agressive", but the screen still gets blue when inclined (even a little bit).
Maybe I'm not familiar with AMOLED screens (I've read it's typical), but I find it very annoying...
It's typical. Most people that continually spout off about how great AMOLED screens are and how they're so superior to LCDs conveniently ignore issues like this. The truth is, LCDs have some issues, like weak blacks if you're in a dark environment, but AMOLED screens usually have even more issues than LCDs, especially when it comes to displaying white and shades of gray.

How white are your whites?

No, I'm not trying to sell washing powder, just trying to understand an issue I've had now with two Pixel 2 devices, and one that I posted about on the colour saturation and accuracy thread on the Real Life Review boards previously.
My first Pixel 2 arrived in December and I was immediately underwhelmed with the colour balance on the display - regardless of configuration options. Whites were very yellow - not as bad as when the Night Light was on, but far from white. So I returned the device, and a new one arrived a few days later. My second Pixel 2 is undoubtedly much better than the first. Not only was the colour balance better, it was also noticeably sharper when compared side by side. However, it still has a definite yellow tint in the whites, and some images seem to show this more than others - for example, flesh tones in the otherwise superb photos (when viewed on the device) look odd.
It's most noticeable for me when I have a nearby monitor or screen to compare. Individually the phone does not look so bad, but the whites on my monitor, laptop, tablet and even old phones are significantly whiter. (I'm not helped by the fact that I work in front of a screen all day - so I'm rarely able to avoid the comparison.)
Hence the question - both my devices have had a distinct yellow tint in the whites. How about yours?
I'd really like to keep the phone - because pretty much everything else about it is great. However, it's not a cheap phone, and because of that I'm not sure I should be making such a compromise on the display.
Any feedback appreciated.
I went to Best Buy and looked at the Pixel 2 they had there, and it had a similar yellow tint to the one I had that I RMA'd, but I don't think the tint was as bad on the one at Best Buy as it was on the one I had.
To get a comparison I just loaded the Play Store app (white background) and compared to a sheet of laser printer paper I had on my desk (under fluorescent lighting in my office). I'd have say my whites were a bit colder (i.e. less yellow) than the paper appeared under these lighting conditions.
I tried changing colour mode, but that didn't seem to have a dramatic effect on the white point, though "saturated" looked a little different - I'm not sure whether I'd describe it as "warmer" (more yellow/less blue) or just having slightly more green, but there was a very small change in colour temperature in that mode. I use "natural" myself anyway.

Thanks for the feedback.... I'm using natural mode too - boosted, or saturated just make the whites more yellow for me. It's subtle - but noticeable.
I've also noticed yellowish whites comparing it to other screens. Even my old N6P had better whites. I don't know if it's a generalized issue we should worry about, or just stick with it.

It's just how these screens were tuned. They are much warmer than LCD screens and look yellow when u compare to basically any other display. It's a feature, not a bug. Stop comparing and you won't notice it ?

You're right of course, I need to stop comparing... I just got a bit paranoid after my original RMA'd device's screen was so poor. I think I'm going to stick with it.

Why is the screen a little warm (yellow tint) on the Pixel 4a

Just moved to Pixel 4a from an LCD display and I notice that the screen is a bit warm. Do others notice the same thing?

Yep. There are some options in settings related to the display (settings/display/colours where you can choose natural, boosted or adaptive which make very little difference, and in accessibility there's a promising looking rainbow under colour correction but sadly there are just a few colour-blind related presets) but nothing which would let you set the white balance manually.

Yep - which I appreciate. Obviously personal preference; native tuning options appear limited based on a bit of early experimentation.
On a related note, integrated "night light" (blue light filter) does a poor job with dark themes; throws off weird casts on light text when scrolling. I find it too distracting to use; just lower the brightness a tad more or use a 3rd party tool.
Looks good to me, where I can tell is looking at skin tones I find them very natural.
Got a picture of a beach water deep blue, sky look natural blue.
Taste maybe but it like it the way it is.
The setting mentioned my screen is on Adaptive, changing it does no effect much ??
Yes the screen is slightly yellowish and can't be changed even with the available presets. Fortunately I don't mind it personally since I prefer warmer whites compared to cold tones.
Yes, quite annoyed in warmth difference in the beginning because I was still using both 4a and my old phone actively. Searched here n there to make it cooler and also tried to make my old phone screen bit warmer to match (cause I just hate the difference not the warmer screen), but I don't like it even further with the tuning
All I can say is give it time, you'll slowly adapt to the new warmer screen
Yes I was just using a Moto One Active for a few weeks, which has a surprisingly decent LCD screen with perfect whites, and now that I'm back to using a Pixel 4a again I'm noticing that yellowish tint. Also had the galaxy s20 FE somewhere in between , which was obviously superior to both lol.
