Nexus Screen looks washed out like a LCD with backlight

I noticed that the blacks on my screen have a strong purple hue... especially when the brightness is turned all the way down. Looks like a bad LCD with too much brightness or backlighting. I thought this was normal for oled since I had never had one. But my friend got a Nexus as well and his blacks look... well, Black.
I thought it was a hardware problem but it only seems to affect certain blacks, like the Live wallpaper and the power control widget. Or the clock app when you hit the dim button.
Screens like Settings and the boot screen look normal. If I turn the brightness all the way up it is less noticeable but definitely still there.
Anybody else have this issue? It seems like a software problem more than a hardware issue since it doesn't happen all the time.
I have now updated to the newest release (2/2/10) and the problem persists
Both phones on Low Brightness:

I do not see a purple hue; however, I have noticed that different apps can have wierd display problems. I thought for sure something was wrong with the corners of my screen since text would get cut off or have lines through them.
However, it was only in certain applications. Try having your friend get the same apps as you then make sure all your brightness and screen setting match. Then look at the same app side by side. If it is that different then I would call HTC and see what they say.

Duplicate post...

I have 2 N1s. One is definitely brighter than the other. It has whiter whites...

Yep, tried the same apps on his phone, they look normal on his but have purple hue on mine. The boot screen, settings, and some others look normal.
Right now I am running a rooted but stock ROM, but the colour problem was there since I got the phone.
The blacks look black in the bootloader and the recovery but once the desktop loads it adds the weird hue to the blacks.
It is especially noticeable in pictures with a lot of dark colours.

I've not noticed any issue like you describe with mine (stock and various other ROMs).
If it's different from your friend's nexus, then I guess you must have a hardware issue (although it may not be unique - I've heard other reports of the same thing).
I'd suggest sending it back to HTC to have them repair it.

If you turn the brightness all the way down do the blacks glow purple? --->

I have a similar situation. I had no problem with the display on my nexus one, UNTIL my girlfriend got one too a week later. When I compare them side by side, the whites on her phone (like the background of Android Market) look much whiter than on mine, which have a yellowish-cast. This is with same brightness settings of course (full-brightness). The colors on her phone just "look" better, compared to mine.
Not really related, but she seems to get MUCH better battery life on her phone too. I'm probably going to try to get a warranty replacement from HTC at some point, but I am glad to hear that I am not the only one experiencing these variations in the AMOLED displays on this phone.
I will add, that I have not noticed a purpleish cast to black areas on the screen on my phone, so maybe there are multiple problems possible with the color casting on these phones.

Actually I think mine has better whites and is a bit brighter than my friends and I always thought his had a bit of yellow tinge.... does hers get a washed out black when the brightness is turned all the way down?

When your brightness is down you WILL get a strong purple or reddish cast in blacks. This is normal for OLED displays. If you dont like it, shut off the automatic brightness and keep it at around 25-30%. The screen looks amazing at normal brightness. But ALL OLED displays have this side effect when brightness is low.

Just compared both of ours side by side with brightness down all the way. I would not say that the blacks on her phone have any more of a purpleish tint than mine, they look acceptably dark to me. Hmmm that is definitely interesting that yours is brighter and your friend's is more yellow.

Thanks, and I would have agreed with you until I saw another Nexus next to mine and dropped both to the lowest setting, my turned purple, his stayed nice and black with proper contrast.
I wanted to see if it was unique, universal, or mixed as to how many people have this issue.
I would start a poll if i knew how. Maybe someone can help me out with that ?

mine behaves the same way as yours, I always thought that this was typical of oled displays but after reading this thread I'm not sure anymore... Ialso noticed this thing http://www.nexusoneforum.net/forum/...ports/1199-amoled-display-issue.html#post9371 could you please tell me if you notice it as well??

Yep, that is exactly how mine looks on low brightness. Notice the purple hue?
And the contacts are a good example... mine look light grey/purple my friends nexus looks just grey, no purple tinge at all.

Strange.... are you going to ask for a replacement? I would but... I'm from italy so it wouldn't be so easy... could you please keep us updated about this thing?

Mine looks nothing like that, with the brightness down all the way everything is still the proper color and black is black. I would return the phone if mine looked like that, it surely seems defective to me.

I think I agree, just didn't want to start the battle if it was 'normal'.
Thanks all for your input, I will update when/if I attempt to get it replaced.
Maybe someone will figure out a proper relock first just to make thing easier

More bright, more tint vs less bright, less tint

Okay, everyone pretty much knows no two SAMOLED screens are the same. I recently bought a second Nexus S (because I kept hearing people say it has "amazing" battery life whereas I was getting nothing better than my Vibrant) and decided to keep my first one (I will return it later) to compare. The second NS definitely has a slightly brighter screen, but it also has a much more apparent purple tint. The first one has a slightly less bright screen but the purple tint is also very minimal, hardly noticeable unless one is looking for it.
Any suggestions on which one I should keep?
P.S. Both phones batteries behave similar so I guess everyone's definition of "amazing" is my definition of poor.

i personally hated the purple tint. if you dont mind the 'unnoticeable unless pointed out' defect, go for the one with the lower brightness. also, check your whites on both phones because mine had a problem displaying true white.

second phone definitely has "purplish" whites.

My personal preference is to have more accurate colors. If the white isn't white, it's not acceptable for me. I'd go for the less bright one, as long as it's bright enough.

Mine has a blue-ish tint when it's white... really annoying. Also there's banding when I swipe down the notification bar (the dark grey background... lots of odd colored lines). That and my oleophobic coating is wearing off, gonna exchange in a few days. I really hope I get one with a warmer tint so the white looks more white... I don't care if it's slightly less bright, it's too bright as it is right now anyway.
EDIT: Actually I just tried screen calibration under cyanogen rendering effects... using the N1 cool setting makes it a tad warmer, whites look white now, but it's SLIGHTLY less bright than before. Whatever, better colors, I like it for now until I exchange.

just for you info, the blue-ish white is the actuall true white . its the better screen than the purplish white. and once you comapre them both head to head, you are gona kiss your phone.
i am not aware of your other issues but if they are annoying you, then just exchange the phone.
god knows how many weeks i searched for cool blue-ish white for my galaxy S and then iphone 4. i hate the warm yellow /purple-ish color from my heart >_< " its a friggin defect "

This is how your NS should look in your screen while in the clock homescreen . If it looks any different, then its not right. Usually there's a purplish tint in the bottom tabbed icons on the lowest bright settings. You'll want to find one thats closest to this display

After doing the test mentioned above (Clock -> hit the brightness setting on the top right corner), I notice that the lower buttons are purple/pink tint.
Does that indicate a defective display? Also, after a few seconds, it dims even more, and the entire screen has a purple/pink tint.

Seems like some super poor quality control if there are huge variances in SAMOLED display tech coming out of Samsung... =[

purple = defective. bad screen
cool blue = good screen.
the end of the day = personal taste. but compare a purple screen to cool blue screen when you set the brightness to the highest on a white background. the difference is night and day

Gah, I knew there was something horribly wrong with the purple.
This is my 2nd unit and I'm not sure if I want to exchange it and take another risk of getting a faulty unit.
My first unit had a faulty back button and this one has a loose volume rocker (not too concerned about), and just found out that the screen is defective.
Now that I think of it however, I'm rarely on low brightness and high brightness.

good luck thinking about it before you go to sleep and you actually sleep.
and if you did, you will have nightmares about it

As I mentioned before, I'm not sure if this really considered a defect in the eyes of samsung because I've yet to see one displayed like the the 2 photos I've provided. I know this because of the inconsistencies I've personally seen with the N1 screens myself, and certain batches of N1 would have varying degrees of the purplish tint, some worse than others. It stills baffles me how they let this bleed over into their NS lines. My NS still has the issue but out of all the NS I've seen so far I've lucked up on the better out of the other evils.

As scary as it may seem, I did have nightmares about it!
I'm going to end up keeping this unit since I haven't ran into other large issues such as rebooting during phone calls, etc.

[Q] Can Samsung galaxy s3 and s4 display pure white color?

I've never used Samsung s3 or s4, so I'm curious to know if it can display pure white color. I've seen many images of s4 in internet but all of them are bluish in color.
Even in the comparision screenshots , its' bluish.
http://www.phonearena.com/reviews/S...-Galaxy-S-III-vs-Lumia-920_id3286#6-Lumia-920
HTC one and Iphone 4 seems to have pure white color but gs3 n s4 are more blue.
I know these images are magnified, so I'd like to know if it can display pure white color and can we find any difference in white color of s4 and LED or other display ?

What's the point of your thread especially posted at the wrong forum if you answered your own question? Lockdown needed.

S3 is white , very comfortable white , I know what you are talking about "bluish" I compare my S3 to my friend's Note 2 and her phone has a bluish display .

The S3 and S4 (and most Samsung devices) have AMOLED displays, which are known for there deep blacks and good saturation, however do not have very good color reproduction, and whites can be terrible.
LCD displays, on the other hand, have very good color reproduction, but can at times appear to be 'washed out', especially if you're used to AMOLED screens. LCD displays are often brighter than AMOLEDs.

first , why is this wrong thread? i'm asking question regarding S4, and it's related to display screen of s4 (so I've asked in general) I've not answered my own question, because I'm asking people what's their real experience. Because the images used in comparison are done with magnified images to give detail information, but in real life We don't see image with that detail.

Thanks , But I think Note 2 is also Super AMOLED display, so I guess that's also similar to s3 or s4.
Have you ever compared your phone display with HTC phones, because I have used htc phone and they have amazing display.

Just switch to Film/Movie mode or Adobe RGB mode.
Adobe RGB color profiles and "film" were set up close enough to the reference temperature of 6500K! average measured color temperature there was around and 6700K 6600K.

Odp: [Q] Can Samsung galaxy s3 and s4 display pure white color?
actually s3 and especially s4 have very good white color and overall color representation. the issue is with brightness and its a totally separate topic.
lcd screens usually use bluish/cold color representation and have issue with white color - temp above 7000 and so on

Oops, sorry! Is there a way to move this question to Q & A section? if Moderator can do this then please move this to QA Section. It's not the best way but at least I've selected this thread as question type.

I got the Note 2 after the S3 and the Note 2 has better whites - the S3 is noticably more bluish.
The S4 is said to have improved noticably over the S3 (see above also), but I don't know if it's better than the Note 2.
I think there is mention on this here also (a good and detailed hands-on): http://www.youtube.com/watch?v=diLD42QafIo

When you root your phone, you can adjust color,cotrast and other colors settings to wathever you want it to be (natural, deep colors etc)
I'm using an AMOLED display. And even that ,I keep deep constrast and high gamma on my phone ,that's not natural but so much more beautiful.

AW: [Q] Can Samsung galaxy s3 and s4 display pure white color?
I read that the s4 has the pholed technology which is saving more than 25% of battery. True or not?

LCD can offer a pure white
AMOLED can offer a pure black
the choice is yours. there are also colour multipliers and gamma settings you can mess with to get the perfect white/black and overall colour combination

A few things:
The Note 2 has noticeably better colour temperature and whites than the S3 (I have both and compared side by side a number of times). The colour reproduction of both can be considerably improved with the Perseus kernel, which has a professionally calibrated screen setting.
The S4 with the Adobe RGB mode has a measured colour temperature of around 6900 (with 6500 being ideal, as a point of reference the iPhone 5 colour temperature measures at about 7100), so its colour temperature and whites reproduction should be just fine in this mode (or the film mode, which apparently is also very good). The current HTC LCD screens (Butterfly, One) actually have very cool colour temperatures measured at about the 8000 mark, which is in fact bluer than the S3 (~7800), so the S4 in the right modes is likely to do better whites than the HTCs (and by a fair margin). I own a Butterfly and was quite surprised to see how blue the whites are beside my Note 2 on stock settings.

my galaxy s4 in the white background at the Bottom of LCD is wiling to violet or Gray.So that the top of the LCD seen Brighter.

I do have, but reversed. At the top of the display the white has a different tone than the one at the bottom (difficult to describe) and with gray/blue backgrounds a pinkish hue appears at the top, together with a stronger background color. It's very clear in apps like play store, currents and zite. Pretty annoying. And that's my second GS4 with the same issue (exchanged the first one as it was a lot worse)

I seem to have this at the bottom a little bit. You really have to look closely to see it, but I think it's there. It also has to do with the auto brightness and contrast switching of the S4. You can see the intensity of the colors changing a lot whem viewing white/ gray backgrounds etc. Are you gonna exchange it again? I think I'm just gonna keep it, since I don't wanna end up with a device with a much worse problem like overheating or worse colours...

I think in your case, as it seems it's not very noticeable, it's indeed better to keep it. I wanted to exchange again, but to do so I need to take it to samsung directly and 1) make them see the color difference (which is very difficult, these people seem to be trained to ignore any defects) and 2) wait maybe a month without the phone to get it replaced, which I can't do. Guess I'll have to keep it like that too :/

Yellow tint on S4 screen

I have this annoying yellow tint on my S4's screen, but disappears when the phone is tilted over 45 degrees. Is this faulty ? Shall I return it ? Or is there a way I can fix the gamma through an app without rooting the phone ?

I have this too, interested if this is a defect or just the colour tone of the amoled on the gs4

I have the S2 and it's blue compared to my display on computer, and I don't even notice it unless I put it against the computer display like you did.
Maybe try other display calibration, I hear you can change them.

Ok, been doing some google research on this -
There's always going to be a slight yellow tint to the particular amoled screen used in the GS4. However, to reduce the effect, set your screen mode to MOVIE.
Movie mode provides the best colour accuracy and also white point of the available choices. I can confirm this is the case having just spent a few minutes comparing colour charts to my girlfriend's very well-calibrated iphone 5.
So I would set it to MOVIE. The whites still won't be IPS display white, but then IPS can't touch the beautiful blacks on amoled. Horses for courses. Hope this helps.

@paddlyaz can you provide sources of where you got this info ? -- Edit : I just tried it, all that did was make the display washed off..Yellow tint still visible

It may LOOK washed out to you - but this is an AMOLED display, which is naturally very colour saturated.
If you compare the gs4 to an iphone 5 like I did just now, you'll see that even in Movie mode, the colours are a little MORE saturated than even the iphone 5 has to offer. The tint is a side-effect of this. IPS displays like the iphone may offer truer whites but amoled displays like the gs4 destroy them in terms of saturation and black levels.
It all depends on what you prefer on a phone.
In terms of the GS4, some people find the 'dynamic' and 'standard' modes vibrant and eye-pleasing - but they're not at all accurate and will exaggerated, innaccurate representations of your photos, videos etc. I have one photo of me in a yellow jumper (fashion mistake I know). When I have it on 'standard' it looks like I just came back from a two week holiday in Chernobyl. In movie mode, it looks exactly how it looks in real-life (i.e. still disgusting but accurate).
Here are a couple of links that describe it more:
http://www.gsmarena.com/displaymate_tests_galaxy_s4_screen_gives_it_the_thumbs_up-news-5928.php
http://gizmodo.com/5995376/galaxy-s-iv-display-shoot+out-how-does-it-compare

I wish I have another camera to show you the difference between my iPhone and S4 ... The iPhone's screen is bright white compared to the yellow tint on my S4. If this is a "feature" then it's not really efficient now is it =\
Maybe there is a way I can manually edit the gamma, this should fix the problem I guess. Or just exchange it for another one.

did you read ANY of my post?!
It's the trade off you pay for having perfect black levels and saturated colours.
The only way you're ever going to see perfect whites is if you get an iphone/htc one - e.g. an IPS display.
But then you're going to be stuck with 'blacks' that are actually grey. And that SUCKS.
People have differing opinions on which trade-off they'd rather have. Personally I'll take a slightly 'warmer' screen in return for having deep, inky blacks.

Hmm I see, so the display type is the reason why the yellow tint appears eh ? Interesting, thanks for the links too, going to check them out.

all screens will be slightly different from each other - but yes, amoled screens will almost always have either a slight YELLOW tint, or a slight BLUE tint - in other words, a slight exaggeration of one particular tone. If you have the time, do a google search and you'll see this was a common 'issue' flagged up on both the gs3 and gs2.
Your best bet is to do the following:
-set screen mode to MOVIE
-disable 'auto adjust screen tone'
-disable auto brightness.
You will never EVER see perfect whites on an amoled screen, and anyone who tells you they have them is lying out of their arse. Most reviews for the GS4 and also in the articles I linked you state that the GS4 is the most accurate amoled screen so far though.
If still disappointed, your best bet is the iphone5/htc one/nexus 4 etc

I think having an exaggerated blue tone is better than a yellow tone, in my own opinion.

Anyone else having this issue ?

I noticed this playing around with the S4 in the store. Still, much better than the S3 white point.

bad yellow tint
Hi everyone,
I received my s4 last week and found it yellowish as well. I have read everything regarding the screen yellow tint and the fact that it's because of the type of screen. I was going to give up but my girlfriend got one today as well and the comparison is very clear: her whites are so much better!
I have tried to take photos of them, and it looks greenish on the shots but you can see the difference. FYI the screen are both using the same settings: auto brightness off, brightness at the maximum, both screen mode in adapt display (I have tried the movie mode without noticing a change).
Mine is on the right if you couldn't see. You can clearly see the difference in the colour and the quality of the screen. I also noticed that the viewing angle are way worse on mine, the phone takes a greenish colour.
Finally I have very strong smearing/ghosting as soon as the screen background is black. For example when I am in the settings, if I scroll up and down, the thin lines separating the sections actually disappear whilst the menu scrolls. The thicker separator get a purple line until the scolling stops. Once again, the smearing on my girlfriend's phone is existant but much less strong. The thin separators are still visible even while the phone is scrolling.
I am definitely bringing it back to the store tomorrow. I am very disappointed with the screen even though the phone is great. I wouldn't change for a One, just for a good one.

I had the same yellow tint on screen and tried a few different firmwares thinking maybe its a software issue but nothing fixed it.
Picked up a new s4 last night and this one is perfect. The thing I noticed is the new one is assenbled in Vietnam and the old one
was assembled in China. Over all the build quality on the new one feels much better along with audio quality.
Maybe a quality control issues in some factories
Cheers

Where does it say the location of assembly ? I want to see where mine is. Also, did you exchange your phone for a new one ? How did you convince them it was faulty ?

You'll see it when you pull the battery, there should be a sticker there.
I am located in Toronto and we dont have any samsung stores here
so i actually bought another one from this dealer i found on kijiji.
The new one was sealed and its from Hong Kong (but assembled in Vietnam)
Cheers

I looked at mine and it says made in Vietnam... But I would agree to say that there is a problem with quality control overall. My guess is that they need to produce as much as possible to avoid any shortage. I had the same problem with my Note 1 and could be bothered to change it, this time I won't let it go.
I will keep you posted.

I had to go to another branch and thankfully they had a model with a white tone screen. I compared it there and they did indeed see the yellow-tone in my phone. I am getting a refund soon, it's not really worth all this trouble i'm fed up of the customer service experience with Samsung.

Nexus 5X: Display Color Calibration Thread

Now that we have our first custom kernel available (Thanks @flar2). We can now adjust the display color settings on the 5X. This will come in VERY handy for those who feel that the screen on their 5X is too yellow. It will also allow you to make tweaks to saturation, contrast, etc. to correct the lackluster color depth that the factory settings provide.
There are plenty of app options for performing these tweaks, but the two below are confirmed to be currently working on the 5X:
KCal Color Control (XDA Link)
EX Kernel Manager (Play Store Link)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
EDIT: It turns out I had a bad device with a yellow tinted display. I've since RMA'd it for one with a MUCH whiter display. So the below color settings won't be ideal for those who did get a good screen on their device.
**Comparison pics of the old screen vs new screen in post #35
Color calibrations used with my previous (yellow display) 5X. If you have a yellower display, these will be good for you:
Red: 235
Green: 245
Blue: 256
Saturation: 50
Value: 130
Contrast: 130
I've spent some time calibrating my new, much whiter screen. They are very close to the settings szucsgf mentioned below in the comments with some more saturation:
Red: 246
Green: 250
Blue: 256
Saturation: 50
Value: 130
Contrast: 130
Feel free to post your results so we can compile some of the best settings here.

Thanks for posting this! How did you pick your values? Did you compare to a calibrated color chart, like the kind used by photographers? Or did you use a colorimeter?

I just eye balled it with the phone sitting next to my iPhone 6S and color calibrated Nexus 6. I was able to eliminate the yellow hue completely and make the blacks much deeper. I know other members here use colorimeters and other tools for more accurate adjustment, so I imagine in time they will chime in with much better calibrations. But for now, my settings are a good starting point to at least eliminate the yellow (warm) hue the screen has by default.

Thanks for the explanation iphones do tend to be calibrated pretty well, but eyeballing it isn't the most accurate method. It'll help get the color balance, but probably not the white, black, or grey points.
As a photographer, I'm actually pretty happy with the warmth in the screen. I find most monitors and phones to be super cool (blue) and that they make my photos look way worse than the originals.

Nice eye ball settings! Looking forward to comparing yours to more "scientific" numbers

iphones are calibrated with a white point around 7000-7200K, which is slightly blue. While many find that visually appealing, it's not quite 'accurate.' 6500K is the target for an accurate white point and phonearena measured the 5x at a white point of 6799K. I've found that while the screen may not look as cool when next to other phones, pictures on the 5x look damn good
I think some issues with 'yellow' screens may have more to do with panels having brightness problems

I presume root is needed for both of the apps?

What's the best way to do this without root? Recommend an app?
XPERIA Z5 GREEN

Root is absolutely required.

Root is required to flash a kernel that allows for these color calibrations. So, in turn, root is also required to use the apps required to make these adjustments.

If you don't want to root, there are apps you can use to apply an overlay on the screen to eliminate the yellow (warm) hue.
One app I used previously is:
https://play.google.com/store/apps/details?id=com.netmanslab.sa
With that app I found that if you leave everything as is and just turn Blue up +10 - +15 it eliminates the warm hue. However, this is simply adding a layer of blue and not truly calibrating the screen. So I still recommend, to those who want to do it right, that you root and use a custom recovery to properly calibrate the screen.
It's actually quite annoying that Google doesn't allow people to make these calibrations in stock configuration without rooting, but that's a whole different topic.

Hey your colors are pretty nice! I like the whiter look on the phone and this is good. Will be using it for some time, thanks!

I notice the OP mentions the yellow-ish tint on the display. Google is actually replacing for this particular issue- My first 5X had an issue with the receiver so call quality sucked and the one I just got in the mail has a very warm hue to it, between red and yellow and after a phone call they are sending me another one.

Can anyone with a color sensor/calibrator calibrate for true white?
True white according to the sensor is usually a lot more yellow than people are used to. I know where are values out for my computer monitor and I was surprised.
I think for the most part, my Nexus 5x is closer to true white than the really cool whites that my M7 had. Though it's warmer than true white on comparison.
I might be try comparing the two and color calibrating based on comparison of whites to my monitor. (My monitor has color calibration settings based on the same model. I do not have my own color colorimeter, it's not worth it since I don't do any kind of media work)
Edit - I didn't end up installing the kernel because I wanted to keep systemless root, and I don't think that was included with the boot.img
However, I do have CF Lumen working and I used the color filter to acheive (reasonably/humanly) close results.
CF Lumen uses a color filter in from 0-1, where 1 represents 100% of the respective RGB value and 0 filters out all of the respective color. Since the colors are appearing anywhere from yellow to more orange-ish hue, I set R to .969 and G to .929 with B at 1.. You can translate that to the results you want in color control by multiplying these decimals with the maximum possible value ( For example R should be 256 * .969) The increment of change isn't as fine as I'd like, but what are you gonna do, it's just a phone. Most phones don't even come close to true white anyway.
I want to also note that your results will vary, probably. These are values for my phone. They're a good starting point. There seems to be reports of huge variations of yellow screens, with some people (placebo? eyes getting used to it) saying it has resolved over a week or two.
Again, most people used to default LED/LCD screen white will even think this calibration is too yellow. Colorimeter calibrations always calibrate for the accepted true white, and therefore will seem warmer than what most people are used to, which is a very cool white. As long as your eyes are happy, there's really no issue I guess. However, I would like to point out that true white is really a lot easier on the eyes than the cooler white that most phones have these days. Blue colors to the eyes seem to "scatter" more and human vision has a harder time focusing with bluer colors. On the other hand if things become to warm, it becomes hard to distinguish things from one another. That's why at night time, or dark conditions, CF lumen is set to warmer colors because at night time vision in the eye has much less ability to contrast and distinguish, and relies more on things like outlines, and movement. (How many times were you driving at night and didn't realize something (deer!) was there until it moved?) Bluer light (most scientifically it's Green, but blue does a good job too) activates cones, and shuts down night vision, blue light is perceived to scatter more and is harder to look at the screen at night, while retaining night vision.

if i install the custom kernel and calibrate the screen, then restore to stock kernel does the screen remain calibrated?

You're talking about something completely different. Nexus devices are known for having a warmer (yellower) hue right out of the box due to lack of display color calibration. Unfortunately, with the 5X, some people are receiving phones with excessively yellow displays. In those cases, Google is replacing those defective devices. This thread is referring to color calibration for screens that are not defective as they still tend to have a warmer hue to them. Some prefer the warmer hue, some don't. That's why this thread exists so people can refer to it to calibrate their screen to their liking. There is no "one size fits all" solution.

thanks, so the screen calibration is managed by the kernel then.
then with the custom kernel installed, what happens with updates? do OTA updates still work?

The screen calibration is managed by the app. But the custom kernel allows for this calibration. If you uninstall the app and reboot the phone, your screen calibration will go back to factory settings.
As far as non-color calibration related questions (such as root and OTAs) please take that to another thread or feel free to PM me. I'm afraid this thread is getting side tracked very fast and I'd like to keep it on topic with comments regarding color calibration tweaking.

Interesting. All I know is the replacement I got is night and day from the first one and Google is replacing it (didn't even require the picture I took of the two). 3 people I sent it to commented on the difference between the two, favoring the first one.

You got pretty lucky then, there are reports of people getting replacements and the color hue was worse. There really wasn't any control checks with the display color calibration in this case.
Big disappointment.

Fingers crossed I get a better one, I really like the phone. At least they aren't pulling a OnePlus and insisting a) you're crazy or b) it's supposed to be piss-yellow. Haven't spent more than 15 minutes on the phone with them in either case
