[Nexus 4 Q&A, Help & Troubleshooting] sampy14:
I posted this in another thread:

what I have noticed is that only the UI and the icons look washed out while browsing, watching videos and looking at photos the colors are perfect.

It might happen because the saturation and contrast of the UI is adjusted for the GNEX display.

I tried this: I increased the saturation of the icons and set up the same UI in a custom launcher; the result was amazing.
[Nexus 4 Q&A, Help & Troubleshooting] overhauling:
Can you share your adjusted color values?

Left - pre ota, right - Post ota. After quadrant they are in reverse. Forget about clarity, just look at the colours. Shot handheld with dslr, so a bit shaky.

Here's your proof that you can see with your eyes that it is ota.
[Nexus 4 Q&A, Help & Troubleshooting] Argenist:
As an owner of both phones (N4 and the iPhone 5), I have been constantly comparing them side by side since receiving the N4.

I am also a digital artist by profession and am constantly having to color correct images, so I would say I am trained to find flaws in color balance and such. Not saying I'm an expert by any means, but I can honestly say that I do find a difference in both screens. Also not looking to fight or argue about terms here with what contrast, hue, saturation and values are... I'm just sharing my opinion.

On maximum brightness, both phones show text very well and crisp, however the difference to me is in photographs. When comparing the same photographs in some of my albums (not shot with phone cameras), The N4 shows a slight white tint that isn't making the photos brighter per say, rather it has a 'washed' out look.

I don't think it's a hardware issue, rather a calibration issue with the phone screen. As some have already mentioned, a simple app or program to adjust values may be able to correct this issue. It's also not that big of a deal. Phones screens are calibrated differently, and same goes with computer monitors.. that's why having two high end monitors doesn't necessarily mean that they will display the same, unless they're properly calibrated.

Anyway, that's just my two cents.
[Nexus 4 Q&A, Help & Troubleshooting] stuart0001:
Thanks for that proof.

I'm sure they were, but were both phones set to the same brightness level?

I'm currently in my 7 day return period and these washed out colours were enough to make me want to return the phone and stick with my HOX because quite frankly, they make the screen look sub-standard and cheap. However, it definitely looks like it can be fixed with software so I'll persevere for now.

And no to those that say otherwise, the current colours are not correct, they are definitely washed out / under-saturated. A comparison against my calibrated monitor and iPad 3 prove that.
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
Yes mate, brightness at 100 percent on both. I was about to send my second one back for yellowish tint, but then realised they are on different ota's. Updated the other one, and they became identical.
[Nexus 4 Q&A, Help & Troubleshooting] ArmandHammer:
I'm running red - 231 green - 231 and blue - 255. (255. = standard).

This has fixed my problems. Green and red still look great but toning them down has made blue finally look blue to me.
[Nexus 4 Q&A, Help & Troubleshooting] ferozfero:
is there anyway to increase ABOVE 255 ...or will it be possible in the future..
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
Nope.
[Nexus 4 Q&A, Help & Troubleshooting] muyoso:
Can't wait until François Simond gets a Nexus 4. He will calibrate the absolute **** out of this display. Brian Klug has been joking about Google hiring him for that very task, since there is no one at Google who properly calibrates displays.
[Nexus 4 Q&A, Help & Troubleshooting] DonDizzurp:
i think the problem is you guys are used to AMOLED with its unnatural oversaturated colours
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
Ahem, i come from Sensation... Some from iPhone. So nope, that is not the problem.
[Nexus 4 Q&A, Help & Troubleshooting] ArmandHammer:
Same her came from a sensation. With the color changes it looks more realistic than the sensation but without the washed look.
[Nexus 4 Q&A, Help & Troubleshooting] idividebyzero:
nope, Im used to properly calibrated high gamut displays since Im a graphic designer, the calibration on this phone is a joke.

Im sick of hearing how undersaturated = accurate. Wrong. Displaying the image as its supposed to look = accurate.

Did you like ore-ota? I think it was quite good. Not quite 100 but not bad at all. Post-ota messed it up.

Rooted and with faux kernel?
[Nexus 4 Q&A, Help & Troubleshooting] djkinetic:
rooted on xylon rom with faux kernel 005 no oc.

finally got it to run, just takes a while to load the interface up i guess.
[Nexus 4 Q&A, Help & Troubleshooting] snail3:
does faux app requires faux kernel to adjust the color? or any kernel will do?
[Nexus 4 Q&A, Help & Troubleshooting] DonDizzurp:
no one said under-saturation = accurate.. but OVER saturation is definitely inaccurate and unnatural, like most AMOLED screens

i dont know why there are so many complaints. i havent received mine yet but my buddy did and compared to his one X you can hardly notice a difference

yes, the one X screen is better, we can agree on that. it is the best screen on a phone ever... but not by much and would make no difference to the average user.

the only thing i can see happening is LG using two different screen manufacturers like HTC does on a lot of its phones.. which is impossible because LG manufacturers its own screens.
[Nexus 4 Q&A, Help & Troubleshooting] stuart0001:
Was his pre ota because it appears the colours degrade significantly afterwards.

I have a hox too and can see them side by side. They are worlds apart in quality with the current software.
[Nexus 4 Q&A, Help & Troubleshooting] Venekor:
I prefer OLED, I've held my GS2 next to an iPhone 4S where ppl say the iPhone 4S is more natural and yet all I see is a dull screen with so much bleedthrough and blacks are grey with poor view angles. OLED looks so much better, even if it is just for the black levels, I hate the back lights of IPS screens...

Just find it funny also people go on about Pentile and PPI............. who ****ing cares? I see the GS3, GN2 and iPhone 5 screens and they all look as sharp as each other :\ Unless I hold the phone under a microscope I don't notice.
[Nexus 4 Q&A, Help & Troubleshooting] DonDizzurp:
pre-OTA and post-OTA show different results

thats enough to prove it isnt a screen issue but a software/driver glitch...

---------- Post added at 06:39 PM ---------- Previous post was at 06:36 PM ----------

im not sure about the s3, but the AMOLED variants of the s2, certain motorolas, the nexus s and to a point the galaxy nexus were all using PenTile amoled and you can CLEARLY see pixelation unless you have bad eyes

and once you notice it, its hard to ignore it and it becomes really annoying

PPI is also an important thing, because it tells you how sharp and crisp images would look on said device

although anything over 300ppi is good enough.. the whole "retina" thing is mostly gimmick..

also, i hate everything apple and iphone represent but the phone has one of the best, most realistic screens and one of the best cameras for a phone

this is mostly because this one company puts all its resources into one device a year so its expected i guess
[Nexus 4 Q&A, Help & Troubleshooting] Endoran:
I'm fairly certain all S2's used samoled+ screens, so not pentile.

[Nexus 4 Q&A, Help & Troubleshooting] DonDizzurp:
huh? what says SAMOLED+ cannot use a PenTile matrix? am i missing something?

also, didnt they use SAMOLED for some?

there are a bunch of different s2's with different screens (or at least according to GSMarena)

i could be wrong, its been a while
[Nexus 4 Q&A, Help & Troubleshooting] ingenious247:
Cannot use? No, did not use. Maybe there is some variant that isn't the plus version. But cannot, is not the reason.
[Nexus 4 Q&A, Help & Troubleshooting] fnf:
Stock kernel will work with some functions automatically disabled in the app.

I bought it but was disappointed that it couldn't adjust gamma though, which is probably what the phone needs. Also you can only decrease RGB values from 255 (standard) which decreases apparent brightness.

Does the 4.2.1 update fix the color issue?
[Nexus 4 Q&A, Help & Troubleshooting] stuart0001:
Is it available yet
[Nexus 4 Q&A, Help & Troubleshooting] Julant80:
Still waiting to get 4.2.1 to see if they recalibrated the settings at all. It seems like with the 4.2 update, Google decided to bump up saturation and gamma in order to enhance clarity when the display is set to automatically adjust brightness. When auto adjust is turned off, the screen gets brighter at 50-60% than I've ever seen it get on auto. My guess is that they were trying to shoot for a middle ground between performance and battery life, but missed the mark somewhat IMO.

At least, I'm hoping that's the reason, and not that it's just a sh*tty display. :p
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
You can apply update manually. I'll do so in a minute or two.

[Nexus 4 Q&A, Help & Troubleshooting] Julant80:
From what's been reported (at least on the TechCrunch article I read) the update is primarily to fix the 'missing December' issue in People/contacts. We'll see if they sneak in any other fixes besides that one.
[Nexus 4 Q&A, Help & Troubleshooting] Venekor:
If I hold a GS3 at a normal distance to my face which is about half an arms length as you bend your arm when holding, I cannot see the pixels in text. I'm sure if I hold it under a magnifying glass then I will but but all the PPI stuff these days I find to be a gimmick. You know really it's at the point where contrast ratio is or response time of the screen.

I absolutely love the display of n4, have never been a fan of amoled displays
[Nexus 4 Q&A, Help & Troubleshooting] stuart0001:
Is it my imagination and me getting used to it or have the colours improved a little with 4.2.1 ?

In fact I'm sure it has as I can barely see a difference between against my HOX now
[Nexus 4 Q&A, Help & Troubleshooting] idividebyzero:
no its still the same

How do you explain the photos posted earlier of 2 phones side by side either side of the ota with clear differences?
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
Latest didn't change anything. The one before it did (for the worse). I'm getting used to the colours too now. Hopefully Google will fix it :)
[Nexus 4 Q&A, Help & Troubleshooting] nbeebe24:
The fact that its two phones explains it. None of our screens are identical to each other, that's just the way it is with mass production. I recommend faux's kernel app as mentioned before. You can play with the colors until they suit your tastes
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
I recommend you READ what I wrote with pictures. :rolleyes:
[Nexus 4 Q&A, Help & Troubleshooting] nbeebe24:
I did read what you wrote... What are you getting at exactly? I can almost assure you there would be a difference in color temp on two different phones running the same build.
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
And I'm telling you if there was, it was negligible. After I updated "better" one they became identical (as I said, if there was any difference, it was negligible).

P. S. Also, there was a link to Google change somewhere, showing they messed with colours.

Yes, screens do differ, sometimes a lot, sometimes not so much. Thing is colours were very good before update on both devices I had.
[Nexus 4 Q&A, Help & Troubleshooting] nbeebe24:
Ah, okay. I remember they did that to my nexus s. You can still control the gamma values though
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
Well, atm we can only lower them to make up for yellow tint, but that's not an answer, since it decreases saturation of already half saturated colours (well, not half). Google has to fix it. Unless someone makes these changes in the rom/kernel, wherever it has to be implemented. If it's firmware, we are stuffed until Google does it.
[Nexus 4 Q&A, Help & Troubleshooting] yomuppet:
Did anyone's colors get better with 4.2.1?
[Nexus 4 Q&A, Help & Troubleshooting] stormtroopercs:
No. No changes to screen.
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
I don't know what's going on. Either my eyes are getting used to the yellow tint, or it's slowly going, but whites look better and better every day. Saturation is still worse than pre ota though. :confused::confused::confused::confused:
[Nexus 4 Q&A, Help & Troubleshooting] idividebyzero:
your brain automatically white balances things, when you put on sunglasses you start out seeing everything as blue/orange and then after awhile it goes away and looks normal. You will only notice a difference when looking at other things with a different white balance.
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
I know how these things work. Into photography a little bit. I don't think it's the brain tbh, or at least not a lot, as I look at things comparatively, not just by pure brain perception (if that makes sense). I can still clearly see that saturation is a bit underwhelming compared to pre ota. I will however compare it to my wife's GS3 when I can. Thing is, it is not unusual for the tint to go, if it really was the glue. Add Google gamma correction to that, and you have a nasty yellow tint.
[Nexus 4 Q&A, Help & Troubleshooting] macr0t0r:
This thread is about how the colors are washed out after the Jellybean update. Yellow tinting is relatively normal with new touchscreen phones and will usually fade with time as the display fully cures. This is common when you grab a phone that is fresh off the factory line.

iPhone users are accustomed to this:

- Jim
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
Don't forget tha some of the yellowness goes side by side with washed out colours. Saturation has decreased(washed out colours) and more yellowness overall has been introduced with 4.2 OTA.

Saying that, after monitoring my phone for almost a week now, it is quite possible glue is curing.
[Nexus 4 Q&A, Help & Troubleshooting] stuart0001:
Well I don't know what the cause is, whether it's the ota or glue drying etc but the colour / white level etc have definitely improved. My colleague even remarked on it after I'd shown him a few days ago and he's convinced there's "more punch" (his words)

I had compared to an iPad3 (regarded as having a reference display) and the N4 was definitely under-saturated but now the differences are almost in-perceivable.

Another comparison with my HOX, same again, it's now very close (although the HOX is known to be over-saturated so I expect some difference). I also compared the 2 with a saturation test pattern using display tester app and with the HOX, the upper colour levels blended into each other about half-way, whereas the N4 clearly showed the steps and graduation of the shades to about 90% meaning it's not pushing the saturation like the HOX

And finally, a look through the camera viewfinder screen shows that what you see on screen is virtually identical to the naked eye.

So I am now delighted with the display and in my view it is extremely accurate and IMO reference. :good:
[Nexus 4 Q&A, Help & Troubleshooting] fnf:
My phone looked the same to me before and after the update to 4.2.1, which it should. As the kernel in 4.2.1 hasn't been updated at all: the kernel revision is the same as the last git commit in 08/11/2012 (e039dcb) which can be found in Settings->About, also there is no patch to the boot.img in the 4.2.1 OTA.

Finally it looks like this was a deliberate decision by the Android kernel team:

That said, I don't disagree with you feeling the display getting better :) .
[Nexus 4 Q&A, Help & Troubleshooting] snail3:
Franco released a new app yesterday to adjust the color (search for "Nexus 4 Display Control" by Francisco Franco in play store)

I bought the app right away since I used his kernel all the time back in GNex days. However couldn't figure out what to adjust to improve the color saturation. would be appericated if anyone used this app and share the value.
[Nexus 4 Q&A, Help & Troubleshooting] desynch-:
I also got ahold of Francisco Franco's display control app. My Nexus 4 doesn't have the whites being yellow issue (it's actually really white), but the settings I've finally decided on that works for me is:

R: 188

G: 172

B: 178

Doesn't look half bad after. But your values may be different. This is at 50% brightness.

I loathe Apple but I have to say that the iPhone 5 screen is better on paper. Check this out:

http://www.gsmarena.com/google_nexus_4-review-860p3.php

While having a slightly better contrast ratio then iPhone 5, N4 has less brightness and worse sunlight legibility than iPhone 4, which wasn't anything exceptional itself. iPhone 5, sadly, beats all other LCDs and most AMOLEDs as well :( But Sharp did do a wonderful job on making the tech, gotta admit.
[Nexus 4 Q&A, Help & Troubleshooting] Shodney:
Anandtech say that it isn't as bright as the iPhone 5, but beats it in blacks and contrast ratio.

http://www.anandtech.com/show/6440/google-nexus-4-review/6

Basically, the screen has the potential to be very good. Just that (as anandtech say) it looks like they made absolutely no attempt to calibrate it, which makes it even more frustrating.

Faux is working on a proper gamma and colour adjustment for his kernel, so hopefully this is something that will get sorted pretty quickly. Whether Google bother to adjust it in an update, we'll have to wait and see.

In terms of sunlight visibility, I don't have any problems whatsoever with mine. I had it in direct sunlight the other day (the low winter sun, which is worse for reflections) and I could see everything perfectly. I was actually surprised at how good it was, coming form the Gnex.
[Nexus 4 Q&A, Help & Troubleshooting] lokenok:
too used to amoled...its not washed out colors. its naturalish color
[Nexus 4 Q&A, Help & Troubleshooting] khawarspirit:
Yes, indeed. The iPhone 5's screen is very similar (if not the same) as the N4 screen. They just sacrificed contrast to get more brightness.

The main problem according to reviews is not the screen, it's the glass protecting it. The iPhone 5 uses a different one to get much less reflectance (even less the GS3 screen, and AMOLEDs are known for their low reflections).

Relieved to read your post though. The GNex screen is bad under sunlight. Thanks :)

This screen is excellent and absolutely brilliant in direct sunlight. I have zero problems using it in the sun.

You can see better details in pretty much anything. including pictures and apps.

Take a look at the picture with jetpack joyride down the page and you will notice the better details in the optimus g than the nexus 4.

It drives me crazy considering that they are the same screens!
[Nexus 4 Q&A, Help & Troubleshooting] littlenoodles:
The problem is that apps choose colors based on the oversaturated past

That may be true - I tend to set my TV's to be less saturated than the factory settings for just this reason. Movies look lousy with the colors oversaturated (unless they're Technicolor, in which oversaturation is a virtue).

But I think the N4 goes to extremes. For instance, in my chat app, received messages are displayed in a gray bubble and sent messages are in a blue bubble. On the N4, I almost can't tell the difference between the gray and blue. Scramble with Friends uses a red block to indicate 'double word score', when I first played it on the N4, I thought something was wrong - round 2 is always supposed to have a double word block somewhere. Turns out it was there, just that the red was so 'subtle' I missed it. This may all be a result of app developers choosing colors based on the oversaturated phones of the past, but whatever, it doesn't work for me. At the very least, if they want to have a 'natural' screen setting, they need to provide a way to control it. Stock Android doesn't seem to have this, and from what I've read, gamma can't be changed without replacing the kernel (I think gamma is the problem, not RGB settings).
[Nexus 4 Q&A, Help & Troubleshooting] ph0b0z:
So i got my N4 yesterday.. quite happy with it.

I still got a Galaxy Nexus here, (which goes to my girlfriend because here Galaxy S got stolen a few days ago.. and i bought it last summer.. had i only known about the upcoming nexus 4 by then!) and well.. i prefer the blacks and i don't think the AMOLED of it is oversaturated, videos look very natural (in comparison to the stock settings on a galaxy s.. that was weird) but hey, now i'm free of the concern of ageing my display every time i use it. ;)

I also think the saturation is the real problem, the gamma is? I just learned about the effects of this and tested a bit with display tester, i first recognized this in the quick-settings menu, where you sometimes (i think it depends on the brightness) can't really distinguish the tiles from one another.

So: Does anyone think it's worth the work to put a nice report into the google issue list / bug tracker?

Also.. this is sad, i always think "get a nexus, everything is fine.." than i had to go through 5 galaxy nexus' to find a decent screen.. now i have to root to calibrate the display correctly. :silly:
[Nexus 4 Q&A, Help & Troubleshooting] ingenious247:
Yep. That's why I stopped buying Nexus products, until Google gets they're act together and forces some kind of standard beyond "lowest price"
