washed out colors after lollipop - Xperia Z2 Tablet Q&A, Help & Troubleshooting

I just updated to lollipop and for some reason the color reproduction is way off now. It looks very washed out. I tried adjusting brightness but it doesn't help. Anyone else ha e this problem? If not I will contact tech support, not sure how that will go....

[IDEA-PROJ] Improve display performance

Hi all,
After reading this, especially this part:
"Suggestions for Google:
1. Eliminate the primitive 16-bit display interface and fix the Browser, Gallery and other applications.
2. The White Point is too blue, lower it to D6500, which will improve color accuracy, slow the aging of the Blue OLED, reduce power consumption, and improve battery run time.
3. Improve the factory display calibration to correct the large color and gray-scale tracking errors and the irregular and non-standard display contrast and Gamma.
4. The color saturation of the display is way too high. You can trade this excess color saturation to boost the screen brightness by adjusting the software color calibration matrices. This will also improve the color accuracy of the display.
5. Take full advantage of the OLED display: the ambient light sensor now just controls the screen brightness. You should also use it to control the gamma, color gamut, color saturation, and edge enhancement so that in low ambient light the display delivers beautiful and accurate image and picture quality, but as the ambient light increases slowly turn up these parameters to counter-balance the washed out appearance of the images in bright ambient light. Also add a display Vivid or Pizzazz control because some people prefer punchy images and pictures, while other people do not.
Nexus One Conclusion: The Nexus One Display Looks Like a Prototype
The Nexus One OLED display has many spectacular qualities, but it is also loaded with lots of rough edges, hasty unfinished beta display drivers and Android software including principal applications like the Browser and Gallery, poorly implemented image processing, poor system integration together with sub-standard factory display calibration. It really looks and behaves like a prototype for a very nice future display, not a finished production display for a world class mobile device that Google markets it to be. It will be interesting to see the degree to which existing units will be corrected and improved with software updates."
My toughts are: could it be possible to tweak video drivers, or at least modify gallery and browser apks to achieve a better viewing quality?
Someone give this man a beer I couldn't have said that better myself.

Any devs watching this?
Wow...even more improvement possibilities! Modding this phone seems endless!
Yeah, I seriously believe we could improve display performance with some tweaks. I noticed that on the iphones 2g,3g,3gs and 4g, the screen kept changing color and it really did make a difference. Like the 3g screen seemed a bit yellow and 3gs was more natural and they kept on improving.
I would like to hear some dev's opinion because I think it's pretty hard to modify video drivers, as we are seeing in the "porting video drivers" thread...so I'm not too optimist...but let's see what happens

As a pro video calibrator I would LOVE to have an app that allows me to change the RGB levels so I can set the grayscale.
I will watch this thread with great interest. Here is to hope.
I think the start is with the rendering tweaks that is being used in cm6. Where that is, I have no clue on the technical specifications..... Sorry.
How many of the issues are hardware related though? They're certainly not going to be updating those.
I'm pretty sure I read that article a few months ago, Google appear to be quite reluctant to do anything specific to the N1 and prefer to just keep trucking along with the generic AOSP development. If anything that can be done is going to happen, it'll be due to the clever developers on this and other forums.
The N1 display looks like it's permanently in store-presentation mode, very sharp and contrasty, unfortunately it's not very realistic. If changes can be made in software to improve things, that'd be great, but I doubt it'll be Google doing it.
grayscale
Would it be possible to have a setting to make the entire display grayscale instead of color? If so, would this then allow us to punch up the brightness past it's default levels? Battery life is not my concern. Seeing my screen in the bright sun is though
Alright, I checked it out using the patch that enables nightvision mode in later CM builds, a calibration profile can most likely be done. I'll get my colorimeter tomorrow and use changing linear transformations to turn one of the modes into a calibrated profile. It's up to Cyanogen whether or not it should be added "officially," but I can just overwrite salmon or something and post an update.zip in the meantime if I can get it to work.
Lowering the contrast (and calibrating for that matter) will lower the total colors that can be rendered, so you'd have to keep that in mind. I'm not sure if the screen is 16 bit minimum (at the lowest brightness and thus the more detail the brighter it is) or 16 bit maximum (at highest brightness) as darkening the "backlight" would just narrow the gamut on the device, anyone know? The gamut may already be too narrow to justify a LUT, but I'll see soon.
From what I know, the system is capable of 24bit color, but only 16 bit native. You see, OLED displays have really high refresh rates, so they show the color above and below the target in the right ratios to trick the eye. I don't think the system does these calculations when it expects the screen to move, too high a load, and that's why tapping on the screen in the browser changes colors. This is probably just the application using the wrong settings with regards to it.
The pentile matrix can show fonts really nicely if it has the right font hinting. I've heard that it doesn't, however. I'm not sure where you'd find the best place to go about that, but it's probably out of the kernel and thus outside of my knowledge..
Edit: heavily edited for cleanliness and new knowledge.
Great contribution Storm...do you think we can correct issues noticed in FIGURE 1 (nexus vs iphone comparison) ? It would be AWESOME ...
Maybe should I open a similar thread on cyanogenmod?

we all doubt it...that's why we're unlocking FM radio and add 720p recording...N1 could really have been the iphone killer if Google did the job ENTIRELY...but really seems that N1 is an unfinished prototype, combine this with huge errors (no marketing and online-only distribution) and you have a partial failure, I know it's sad to say...
Still love my N1!
Well, it looks like the calibration profile is going to be [1, .98, .69] [R,G,B] or thereabouts. Can anyone test the temperature with their own calibrator? I'm getting 9300K when we want 6500K, the website noted earlier got 8900K. I'd like a few more test results but I can work with just my own.
I'm going to edit the files and try it out on my phone here soon enough. I can, if I can modify by-pixel colors, calibrate it to a 2.2 gamma, which would lower battery usage and the overly contrasty and cartoony colors significantly. It'll take a while though if it's even possible.
Anyone know any good apps that just show a specified RGB value across most or all the screen?
Edit: Alright, there are two calibration profiles, one for the lowest brightness, one for the highest. The values I'm getting (for the code junkies) are [1, green, .82] for bright screens, and [1, green, .80] for dark screens. The problem is that the level of green is pretty subjective. I can't measure it without doing extensive calculations, but comparing it to my calibrated monitor, .98 or .99 seems good. 1.00 should be ok, as .98 will add banding.
I'll upload the libsurfaceflinger.so with the modified profile for people to test in another thread (to be linked once I make it here)

This is awesome! I will certainly test tonight with my X-rite i1 Pro meter. Just curious, where are you getting the IRE images from?

As of now, I don't have IRE images. I just calibrated the white point, and even then, kinda inprecisely. Your data and inputs are valued, but I can't do anything more than a linear equation on the pixels. Currently, I keep red as it is, multiply green by .98, and multiply blue by .82 . It's not accurate, but it's close, and it uses less power. The gamma is still skewed to hell though.

[Q] Vibrant over saturated colors

Hi all,
I have a feeling that my Vibrant's colors are over saturated.
Is there any way of modifying the color settings to make them less saturated?\
Thanks
I think theyre not. Theyre just they way theyre supposed to be
Yes, Galaxy S colors are oversaturated by default.
I address this with current Voodoo color patches, restoring the saturation to its normal state.

So what, you're washing the screen out now? Awesome! I guess the next step is replacing it with a regular LCD so we can also miss out on those viewing angles and black levels.
The images you're looking at are probably oversaturated or have color distortion.
Yeah, they are definitely over saturated but I think its better like that. I would say that the iphone has a very good balance between normal and oversaturated colors but it just depends on choice.
I am a digital photographer by trade. I use pantone monitor calibration to get that perfect look then biuld printer profiles so what I see is what I print.
I ran the sensor on my vibrant it its up on all the primaries by 2-3 points. Many cameras add this, especially the point n shoots. We live in a high def oversaturated world. On the Vibrant to me this looks like an unscientific adjustment to fit the times. I can just see the Samsung tech guys with sliders and executives saying, "thats good, right there ". Yikes.
They did the same with the head phone output being inhanced and not transparent.
Not sure they thought they would run into us tech heads.
In all honesty it doesn't bother me a bit. I leave it as is.

Brightness/contrast issues on G5

Just got my G5 two days ago and while comparing it to the S7 in the Verizon store I couldn't tell too much of a difference. Obviously the S7 is brighter with better contrast but when I came home I compared the G5 to my old S4 and pictures in on the S4 look so much better. The colors seems washed out on this phone.
Is anyone having issues with this? And does anyone know of a way to adjust contrast on the phone? I'm seriously considering returning it for the S7 at this point.

Mine seems kinda washed out. It's not all the time though.

Samsung phones over saturate all the colors as a way to sell the phone imo, so when you see it on display it tends to pop out more. So in contrast it will make the G5s screen look dull in comparison.
I've taken pictures with my G5 and compared the color to original object and it seems close to the true color temperature. My GFs GS6 on the other hand clearly looks overblown when comparing the picture taken to the object. With that said, I think the colors on the G5 are also overblown just a little.
Contrast is no comparison, OLED will always win.. Especially in dark environments. But I've been very impressed with the G5 in most lighting, although some lighting does expose weaker contrast.
you can't compare LCD to Amoled, obviously Amoled is more superior.
you should compare it to other phones with LCD display.
I've had my G5 for a few days now and I absolutely love it. Expect, recently my phone would dim on its own, just enough that it's noticeable and irritating. I've checked all the settings and the auto mode is turned off. I know other people have/had this issue. Is there a fix for this?
Thanks in advance.

On the G3
There was an option to increase contrast on the G3. I'm not sure whether it's on the g5 though. I can't post links yet but search in google- (droid life color adjustment g3.)

I've messed around with those and sadly it doesn't help. A simple option to adjust contrast or colors would work wonders., imo.
As for the previous comments, I should have been a bit more clear on my complaints. Yes I'm aware AMOLED is superior to LCD but the difference I'm seeing is bigger than it should be. The colors were better on my old HTC DNA. Just like any new LCD TV, you have the ability to adjust picture settings and I can't imagine why that's not an option on phones.
Aside from this complaint, I really do like the phone. From my understanding, LG has been really good in the past about Android updates so hopefully some of the complaints will be rectified with updates.

Its just a matter of waiting now, as soon as we get root a whole new world of possibilities will open up

Color saturation & accuracy

If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the LG G6's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!
The LCD is fairly color accurate all considering. This screen is very close to what I achieve using a hardware color calibrate with my work machines. The reds are not too red (faux saturation) and the cooler tones show up as prominently.
It's just a shame I can't hook up a hardware calibrator to it to test it.
Solid color accuracy
I am coming from a OnePlus 3T, so when first firing up the G6 I was a little disappointed. I couldn't believe how much more vivid the AMOLED screen was compared to the LCD. Well, now that I have been using the G6 exclusively for the past two days, I am growing quite fond of this screen. The colors are quite accurate and precise, just not as vivid/saturated as what I was looking at for the past 6 months. Liking this phone more and more each day.
The screen color temperature is definitely on the cool side, certainly higher than 6500K.
It is not pleasant at first for me. I've been using Nexus 6P on sRGB mode for more than a year, and the color saturation on the G6 under default, out of the box settings is disheartening.
To somehow mitigate this, what I did was to enable ComfortView, set at Low Setting. It's far from perfect, but that's better than nothing.
How is this compared to the S8/+ ?

From what I saw side by side compared to the S8+ at full brightness, I could see the whites having a more pinkish hue very slightly than the S8+. The S8+ having brighter highlights. Obviously, the S8+ also has deeper blacks, more saturated, and viewing angles are much better because of its AMOLED display. Other than that, the overall range of colours seemed fairly close between the G6 and S8+.
Not sure who will see this but I think the G6 LCD screen compared to an amoled like the one's on the oneplus 3/3t/5 and the s8/s8+ is just better in certain scenarios. There are some people who might be audiophile esque and want high fidelity and things like that. And there might be some people who like bass boosted beat headphones and other things like that which are not accurate at all but are enjoyable on a certain level. If you like big bass sound and you are that kind of person then you will like the amoled screen but I am personally not. I like knowing that what I see on my screen is what it is supposed to look like.
For instance the other day I was looking at a picture of the fifty shades of gray poster. It is supposed to be black and gray but it had a colored tint to it on the s8 compared to a g6 which looked as it should. All I am saying is that there are going to be times when the s8 because it pops colors so much will make what you see innacurate. And that might bother you or it might not. But it bothers me.
Exactly what Scape said. Tech people who know their stuff want accurate color reproduction and analytic sound. The wide mass wants flashy Colors and boomsound. Easy people rate phones by how saturated the phone looks. The more saturation = the better. This is complete BS for people who have knowledge about Electronics. Its like comparing people who buy a Classic car and put Chrome rims on it not caring for the paint because "CROME RIMZ M8". Where there are also people which buy a classic car, care to make it look as original as possible and know every part of their car.
The 2nd. Car may look boring to people, but its quality and worthwise extremely preferable. For example a natural Color reproduction can help when taking photos with the G6. If you take a photo on the Amoled Screen of a Galaxy, and then open it on your calibrated IPS, you will be flashed about how different it looks then on the phone. Thats not what you want.
Regarding the Bass... Well i like perfect color recreation but i hate neutral speakers or headphones, im quite a basshead but i still want a good clarity, deep stage and low noise.

Yeah, i kept my custom color setting enabled for a few weeks since the blue color looked way better. It is only when switching back to the default setting that i noticed how washed out the reds looked. I reverted back to the defaults.

I bought G6 after iP6S+ and I'm really disappointed from display over all. Blue is on G6 boosted as hell. At home I have calibrated displays and iPhone is much more closer. I can't watch photos (photographer) on G6 because of it. Even automatic brightness control is not ok for me. It's still dimmer than I want. LuxLite solved that but colors are terrible.
Why my phone is reporting me that I have screen resolution of 1440x2703 and PPI 544? https://imgur.com/a/lNXhw

This is bad news for me, I find the G6 screen beautiful (I am under 7.0) and I do not like at all the rendering amoled screens, precisely because of the saturated colors..
I found on 7.0 that the flesh tones on netflix and terrarium tv were way washed out.looked like everyone never saw the sun lol Na just saying I think LG just corrected the saturation a little bit to not make things so washed out looking.The reds are a little darker also instead of a orangey yellow tint.And like before the greens were not as dark .kinda reminded me of a mint or pastel green.Now on Oreo it is a true green and red.
Is there any app or any online guides to correct the LG G6 color accuracy and get true neutral white balance?
I have s8 and G6. I hate Amoled with that compotish colors. White is not white. Ever with pink or blue or yellow. Amoled is like woman with silicon tits. Far from reality. For me LG and Sony make most better displays.
Does anyone use this? I did for a while. I found it very good at adjusting the blues making them a bit darker FB looks much better IMO after I adjusted it

Disable EUI color shift?

Is their a way to disable the colors shifting in direct sunlight? Kind of distracting in my opinion.
Was about to ask the same, the lose of saturation in sunlight, right?
Pretty annoying​ to me.
Also asking for a solution here
