[Q] Faulty Screen? (large images)

Can anyone with a Nexus S have a look at these photos and compare against their own? I want to be sure my screen is faulty before taking it back. Thanks.
Left: Galaxy S i9000 Right: Nexus S. Both with auto-brightness on.

Nice sharp clear text on the i9000:
The same text on the Nexus S:
Looking from an angle, the screen turns even more green/yellow:
Then with brightness turned up full on both:
Now looking from an angle the screen has a very blue tint on the NS, where the i9000 doesn't discolour at all:
The screen starts to look much better after about 50% brightness. Auto-brightness makes it look awful which makes me think the colour profile for the panel is wrong as if the brightness is set to full it's overly bright and has a blue tint.
Does anyone else see this behaviour?

I do have a vibrant so I can compare in the same way... but again there's also differences among Vibrant panels. Anyway, my Vibrant is a bit more blue tinted than my Nexus S, and overall the Nexus S display seems nicer. However, as for viewing angle, the Vibrant doesn't distort at all, while the Nexus S changes color slightly, which I think is due to the gorilla glass in the Vibrant and lack of it in the Nexus S.
Your first pictures... I don't know if it's because of your camera's white balance, but the Nexus S is way too green. If anything, the Nexus S should be warmer (redder/yellower) than the Vibrant, which is what I see and was also reported by many reviewers. Also it should have exactly the same sharpness, so I think your display is kind of messed up... exchange if you can.

It's faulty. I have 3 Vibrant's in my hands right now due to my internal speaker stop working and getting warranty replacements. The warrant replacements both have blue tinted screen, so I asked for yet another. The original Vibrant I had has no blue tint and is gorgeous, but the Nexus S is even more vibrant and gorgeous.
You got a SAMOLED dud exchange it!

Yeah, your nexus S needs to be exchanged.
My S Screen looks even better than your i9000 phone. The colors on the i9000 look a little washed out, or not as vibrant. Of course that could just be the camera your using

Samsung QC appears to be utterly awful.

For the amount of phones they put out in what seemed like a rush, I think they did a decent job.

to be honest i am kinda tired of going on repeat about this. but there are many bad screens. check my post history. you will find your aswers.
what i can say is there is warm yellow white " defective screen " and cool blue white " good screen "
one of your phones is defective.

Ok I'd say your screen is defective. Funny I placed my nexus one next to the S at the store, and the store unit had exact same issue as yours. My nexus one whites blew it away, it wasn't even close it was that bad. It's screen had some weird tint color like yours. Must have been a bad unit as well.

sorry. i didnt mean to be rude . its just i explained it few times. and i am lil lazy so type it again but i wanted to help you out so i pointed you to my msg history. all good tho

No worries dude. Thanks for the help. Hopefully more people will know what to look for now.

Sorry for bumping.
My Nexus S has same bluish display when screen brightness is low, exactly same with the pictures in the first post.
When I dim the screen in Clock Application, I can see the purple buttons instead of gray.
When I compare with HD2's LCD screen, HD2 looks even better :S
Should I exchange it? My friend bought it from Bestbuy for me, and I'm not living in US. So it's really hard for me to exchange it :/
Does it really worth to exchange it?

Washed out viewing angle

Can all of you people with "perfect" displays and viewing angles post picture of your device at an angle if you were look at it from a table and other angles.
I DON'T CARE IF YOU LOOK AT IT FROM THE FRONT and say "oh well I look it from the front all the time." I view my device on the table 1/4 time. So this is an issue. Don't get me wrong I love this device.
MINE IS BAD. I know there are threads similar like this but you people NEVER back up your claim of it being perfect and saying "I don't have that issue."

WELL PLEASE POST PICTURES OF A LOT OF ANGLES! PLEASE AS PROOF!
I'm trying to investigate this issue because I'm reading the display on this device is the BEST DISPLAY EVER. I don't believe this is true at all. MKBHD has this issue too. I add this device for a week and I know I have only 15 days before it's too late to get a new one and not a "refurbished" one.

If you perceive it as an issue you might want to go with the next badass $350 off contract device available... This is something that is mentioned in almost EVERY review video I've seen, but I don't read my screen from an angle and don't see it as an "issue".
good day.

I've only seen two videos point this out and I hoped it would be a defect. All the others out said this display is "perfect" and so on etc.
I want to see the pictures from the people who claim the "perfect" display and says "I dont have that when I look at mine from an angle."
Cuz I've seen plenty who claims that in just one thread involving this issue. Yeah it's a low priced device, but we all know Google doesn't really make money off this device at all, it's the services your using and the ads you see when your using it that pays them back.
I just want to see the pictures of those who claims their device is perfect.
Sent from my Nexus 5 using Tapatalk

Reviewers may test extreme viewing angles for comparison but generally evaluate the quality when viewing the display head-on in the manner most people view the device while it's held in normal use. Mind's perfect, but I could not very well use it if held at a 90° angle.

My viewing angles are nothing like that. I have no trouble seeing my screen from those angles.I know you are looking for pictures but unfortunately m n5 is my only camera right now. If i can get some pics I'll post them.

Mine ain't perfect but they seem much better than yours. At least with my eyes, maybe your camera make the things worst ?
I don't have any camera either, but seriously I can see the tiles much better than you, even with extreme angles.

Galaxy Nexus. Yah i know blah blah blah blah saturated. I deal with a HTC ONE too. I actually ENJOY the display on the ONE more then my Galaxy Nexus. THAT display is GORGEOUS! I wish I could just tear it off and use the ONE's display instead lol. Or at least get the viewing angle it gets.

Heh, I wanna say galaxy nexus. Which I also came from as well. Galaxy nexus amoled panel blows chunks next to the n5.
On topic: Since you forced me to sorta care, I got to lookin at the angles. When I got directly up/down/left/right it performs as well as an ips display should with solid color at extreme angles. But on the diagonals of the extremes i.e. (Right/down) I noticed that's when the back light washout would be visible. I suspect it has something to do with any type of polarization that has been applied to the glass.
good day.

agreed.

Have you ever noticed how every review tests viewing angles from a straight angle? That's the standard and probably for good reason.
Sent from my Nexus 5 using Tapatalk

Mine wishes out when I look at it diagonally and off-axis. There's only minimal washing out from the top, bottom, and sides, unlike what you're seeing. I'll try to track down a another camera and take a couple photos to show you.
EDIT: Here you go. As you can see, there's some washing out at extreme angles (mostly from the diagonal), but it's nowhere near as bad as you're experiencing.

Which is why it's bad for viewing on tables like I said. Because your viewing it from diagonal perspective a bit. Left and right and up and down are Barrable. It's not TOOO bad. Of the diagonals were the same I'd be OK with this.
I wanna know if this is a Screen lottery (every device has this but some worst then others), which is why I requested pictures from the "perfect" people. If I see that they are having even a significantly better display compared to mine(I know IPS displays get washed out at angles but mine is HORRIBLE), then I wanna call Google and get a new one and compare those too.
I've yet to be able to compare my Nexus 5 to another. Probably tomorrow I'll go into a T-Mobile or Sprint retailer and compare (hopefully it isn't bright in the room because it's harder to tell the difference).

Stock kernel, no color adjustments. I've never used max brightness on any device. I'm at roughly 1/3 brightness and it's still plenty bright for me. I can try another one at max brightness if you want, but I don't keep it that high personally because it's too bright for my eyes and it also kills the battery.
EDIT: here's max brightness.

No Maxy it's fine thanks. I just wanted to know for sure.

Yeah they're bad. So was the nexus 4 and g2. It's the type of polarizer that LG uses.

Someone at LG needs to be FIRRRRRRRRRRRRRRRREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEDA.
Can this "issue" be fixed? Can the angles be improved? I remember reading the Nexus⁴ got some AOSPA Love and it got "fixed" not sure if it was color wise or angle wise or both since I don't own one.
Sent from my Nexus 5 using Tapatalk

Mine gets quite washed out an angle, but I can still read everything on the screen just fine so it really doesn't bother me. It's a little annoying and unfortunate just to know it's like this (especially since my N7 2013's IPS screen is absolutely perfect even at the most extreme angles), but it really has no effect on my usage of the device.
Seems extreme to wish for someone to lose their job over this. If this is affecting you enough to feel that strongly about it, perhaps a different device would serve you better.

My point in posting those photos was to show that it's really not that bad at all, and it actually looks worse in the photos that it does in person. To suggest that someone should lose their livelihood over this non-issue is utterly ridiculous because this screen on this phone is pretty awesome. And I'm picky about displays.

Disadvantages of Galaxy S5 and request for future phones

Samsung please make in the future smartphones:
OIS
Remove modulation at medium and low brightness, as it did in the Fly IQ444 Diamond 2 Quattro, Motorola Razr HD (XT925) and LG G Flex

Remove Dynamic and Standard modes. These modes are as bone that samsung threw for some reviewers and haters. Benefit from them is no, only cons. Because at testers gray is blue, red is orange, they specially put this modes, they have very cold tone (6500-6700K - Cinema and pro photo mode, 7500-8000K - Dynamic and Standard). Anyway all image are designed for SRGB standard, and enhanced range is color distortion, red hues (at normal color temperature) and oversaturation.
Сomplete yet color gamut to 100% SRGB, the unnecessary 6-7% still sometimes make themselves known. (but 106% instead of 122% in S4 is a good job).
http://www.youtube.com/watch?feature=player_detailpage&v=7PP8mgv0eCY#t=798 (This is Cinema Mode)
Metal Body (antennas should be behind the plastic, glass or other material, but not metal, so did HTC, Apple and Sony, otherwise the connection will be very bad).
Thanks
It would be ideal. Isocell, improved super amoled (brightness, viewing angles, color reproduction in cinema and pro photo mode, anti-glare), waterproof, interface speed and battery life is awesome.

Who are close to the developers of samsung, please show them this post

I'd think there are many more important issues with phones nowadays than screen calibration. If you want to edit photos, get a good monitor and calibrate it. If you want to watch movies, get a 65" plasma or OLED and stop complaining about stuff that has little relevance in smartphones.

It is much more important than unnecessary megapixels, megahertz, cores and ppi's.
It's about quality of display, which can be much better,
about the impact on eyes and eye fatigue,
about shooting in low light,
about solid and feeling that you hold the thing for ages
about "vulnerabilities", which can fault reviewers and haters

I prefer a fast phone with a perfect screen, than a slow phone with a good screen.
We already have good screens and if Samsung devotes loads of hours to making the screen much better, they will either need to make the phone super expensive to pay for those extra hours or they will have to cut corners in other areas to save money.
The law of diminishing returns - you spend 10% of time to achieve 90% of what you want and 90% for the rest 10%.

Less screen modes? More accurate? It will be a cold day in hell when Samsung stops emphasizing the saturated colors that only come from AMOLED. There's a reason why they use it on all flagships.
Lots of people prefer that saturated profile.
I would be always against taking choice away from customer.
Cinema is quite good Btw. Not perfect but it's close to accurate.
First thing I did when I bought this phone was changing the screen mode. That's Android strength: let me choose.
OIS: yes please.
Metal body: only if it's not form over function.

The main advantages of amoled is not oversaturation and distortion. The main advantages is ideal black color, ideal contrast, ideal viewing angle, ideal response speed, all much better than lcd

Z3 color accuracy and tint/temperature?

I consider to buy Z3 ( Dual ) but I also concern about colors accuracy and tint.
GsmArena reviewed but doen't mention about this. According to PhoneArena, Z3 screen temperature scored 10324K ( poor ), Delta E GrayScale also 9.28 ( poor ). 10k color temperature mean Z3 screen has blue tint?
http://www.phonearena.com/reviews/Sony-Xperia-Z3-Review_id3795
As @robbiekhan shared some photos about Z3 screen:

Could you share your opinion and experience? Thank you!

yes the screen is blue biased and this is by design. It allows higher brightness at the cost of color accuracy. As this is a mobile phone and probably not used for professional print/design tasks I can understand this choice.
The normal user will not realize that the colors are off. But normal useres will apreciate the great brightness and poppy colors (with color enhancement on) - this also might result in some battery savings as lower brightness is required when the image itself appears brighter.

Yes! Maybe for power saving reason. But for higher brightness, better visible under sunlight and color accuracy, Apple iPhone 6/6 Plus still manage very good screen as GsmArena and PhoneArena reviewed: high brightness, much better tempurature, better sunlight contrast/viewable.

To be fair, the iPhone doing anything shouldn't interest anyone who has an Android phone as I phones don't do much with that screen.
As for this one, the white adjustments are in the settings so you can calibrate how you like. Id like to see an iPhone let you do that. .
Plus, the Z3 doesn't bend in your back pocket

To be fair, I said about iPhone because of same IPS screen. For Android phones, some other phones also have more accuracy color, better calibrate screen. Z2 also have better about color accuracy, of course lower brightness, very good battery life.
By the way, could anyone share how to calibrate Z3 screen? I ordered Z3 Dual!

Hi again.
My last reply was meant to be light hearted I hope I didn't offend.
I went into my display settings and under white balance, put the Red up to 95. Green to 45. Seems to mimic my old phone, HTC One, very well. I'm sure adding some green might help and I imagine people will share their settings over time.
Maybe not perfect but certainly looks better to me

I'm not sure exactly but, I have a i1 DisplayPro which is used to profile monitors. I'm thinking of using that on the phone so I can most likely have the white balance calibrated to 6500K manually as it would tell me where to adjust the RBG respectfully.

This is my white balance calibration
Sent from my D6603

WTF?
Are you really comparing the colours produce by a mobile phone, to that of a monitor?

The Google Nexus 5 may have a slightly "yellowish" display in comparison to the Xperia Z3's very cold default color temperature of 10324K (as noted by PhoneArena.com's review) The "real" white point is 6500 Kelvins, and the Nexus 5 is very close to that. (6786K)
I tried to compare a white background between my Mum's Sony Xperia Z3 and my "color-accurate-but-low-gamma" Nexus 5, while tweaking the values using the built-in White Balance utility on the Xperia Z3.
I used the app Display Tester:
https://play.google.com/store/apps/details?id=com.gombosdev.displaytester
After several intensive adjustments, I've settled on either 3 of these configurations: (My favorite is Config B)
Configuration A: (less yellow)
Configuration B: (more yellow, as yellow as Nexus 5)
Configuration C: (in the middle between the above 2 configurations)
The problem? The reds and greens on the Xperia Z3 are still slightly oversaturated, compared to my undersaturated Nexus 5. And a totally black background on the Z3 has a slight reddish tint. This also affects very dark pictures.
But overall I'm pretty [emoji28] happy (and relieved) with the still amazing display of the Xperia Z3.
Any one willing to shed some more light on the matter?

Not a professional recommendation but I've settled with 190 (red), 180 (green) and 115 (blue) although I'm keeping an eye on the thread generally ?

That's because the nexus 5 has a washed out screen due to its low gamma. If you compare the Z3's screen to the m8 for example the saturation will be similar to each other

I'm ok with my setting:
Red: 61; Green: 9; Blue: 0

If anyone want a bit yellow tint, they should increase both Red and Green to about 1xx.

how's everyone's screen color uniformity?

I'll never in my life get a perfect phone.. ever. out of every android I've had, none have ever been perfect.
either way, how's everyone's screen uniformity? I just realized that my screen is brighter towards the bottom left and much darker as it goes to the top left. so annoying. only really notice it on gray backgrounds ugh but you can kinda even see it on white too. pretty annoying but i really dont know if it's even worth swapping it out, because i know with my crap luck I'll get another one that's even worse.
so how's yours?

My flat S7 has a bad screen too : Pink / Green color shift from top to bottom...
I already had this problem with 3 different S6 so I'm really disappointed the issue is still present with the S7. Got a RMA but it may takes 3 weeks for a replacement thanks to the ****ty consumer service in my country .
Here is a shot of the problem (the 2 shots are the same I have just augmented contrast on the second one to clearly see the problem).

damn, thats definitely worse than mine. the bottom of mine is just brighter and the top is darker, which can be a bit annoying. I notice it if I go landscape and pull down the drop down bar if I'm using a theme that has a darker color.. or if the status bar is colored like hangouts, the left side (top) will be a darker green than the right (bottom) which just looks brighter.

Yup...same on my new S7. Green tint on the bottom, pinkish tint on top. Not as pronounced as on my previous S6, but still noticable. Have to use the phone a bit the upcoming days to find out how much it will annoy me, and whether I will return the phone.
Same ol' same ol' Samsung

damn! widespread issue huh. guess that one website that said it was the best screen ever must have gotten lucky with a good unit! hah

oh yeah, S6 story all over again.
"that website" gets cherry picked units and never ever reports on physical defects like discoloration or gray uniformity.
it's a great screen otherwise, ha!

haha damn! oh well. I mean I can kinda notice it even on white now where the bottom of the screen just seems slightly brighter. meh, I'll learn to live with it sadly lol

hmm. well, gray is the WORST culprit for AMOLED screens to show fault. man, i remember the galaxy s3 days when I worked for verizon..when i was ready to buy mine, i checked each phone before picking the one i wanted because no lie, i saw so many amoled issues with splotchy screens and just lines in the screen that you can see on gray. remember hte days of blotchy ink looking on a black screen too? man, this is kinda reminding me of the S3 days haha nostalgia i guess..

if anyone has a screen with perfect gray uniformity (and without pink / green discoloration), please post.

My got this problem too. I'll send it back to service on Monday, don't want to ignore this issue.
On bright screen it is difficult to see but on lower screen in dark rooms it's an disturbing effect.

notice the pink / darker bottom of the S7E (and i bet the gray test will show that part to be darker too) against the perfect Note 5 screen in this video:

This is a common problem since the Galaxy S2 days, a lot of consumers have accepted this as a norm which leads me to believe that samsung is just slacking on the quality control. Im getting an S7 soon I have high hopes on the screen lottery..

It's not as worse like on the picture but truly uncomfortable
Gesendet von meinem SM-G930F mit Tapatalk

yeah mine isn't as bad as the picture either. the picture definitely brings out looking worse haha

Very weird
An amoled screen should be pitch black, for it does not activate black pixels, i havent see this before, you should go back with your S7.

those are gray images not black.

so here's some anecdotal evidence. went through 3 Edge and 4 regular display models and only 1 regular (gold) variant had perfect grey uniformity and pretty even whites. the rest showed very pronounced gradient effect with the grey background on either top or bottom.
