Google Edition ROMs color reproduction - AT&T Samsung Galaxy S 4 General

They seem different than the way TouchWiz ROMs are calibrated. More accurately to say the least. Whites in the browser are significantly brighter, making them more white and don't have that yellow tint to them TW ROMs do. Or am I just crazy?

I do think the screen is tuned differently. Unlike with TouchWiz where you have different screen modes for different accuracy, vividness and color temperature, the GPE is just locked at Google's stock tuning.

[Q] Daylight brightness?

Has anyone come across a review that shows how readable the screen is in direct sunlight vs. something like OLED on the S5 & Note 3?
S4 was horrible. Note 3 is barely tolerable.
If the OnePlus is drastically better than the Note 3 in direct sunlight, then that may be what pushes me over the edge.
And I mean TEXAS sunlight, not some wimpy sunlight from other states.
Could you give examples of what screens are tolerable then maybe someone could compare? (with Texas sunlight)

I have yet to find one that meets what I think should be acceptable. But all the superphones are getting brighter & brighter each year. I'm hoping the OnePlus may at least be as bright as the new S5 which is supposedly the best daylight Android phone out right now.
It's obvious that not everyone cares about this aspect of phones. But I think it's one area that is waaay behind where it should be.
Someday people will have phones that are incredibly easy to see/read under direct sunlight and they'll think,,, "how did I ever live with that old phone of mine".
Just like how I feel now about the old 4" phones that I once thought were "too big". :good:
Btw, one trick is to use lighter colored themes.
I generally love running dark colored CyanogenMOD themes and they do make it much harder to read in daylight. A lighter colored theme helps a lot.
Some AOSP ROM's have the "dark theme" built in and allow auto-switching between normal and dark themes depending on light conditions. Which is fantastic! But the "normal" theme itself is actually kind of dark also.

[Discussion] AMOLEDs are awful. why do you people like it?

I'm just gonna say a few things about Samsung's AMOLED displays. people all over the internet say Samsung phones have the best displays.
lets me start by saying a few facts about AMOLED. then tell me why samsung still uses AMOLED instead of IPS or why people like it:
1. AMOLED dipslays have a terrible purple smudge. specially when they switch from black to grey they show a purple tail. this is super annoying. my s7 edge is just unusable.
2. Longevity. they lose brightness and color and change overtime
3. Burn-in
4. Power consumption showing Whites are higher than LCD. and Samsung phones all use white themes at default...
5. Color accuracy. it's nowhere near iPhones IPS. specially with iPhones wider color gamut things look better.
6. Cost more to manufacture.
7. Pentile pattern makes everything look. weird. whites look rainbowish. they need more resolution to achieve the same look sharpness as LCD.
8. They're awful at showing whites.
my Knowledge is based off the internet and eyes. I'm not god I might be wrong.
and remember this is a friendly discussion. not a fight!
I love AMOLED because of the deep blacks. I use the Reddit is Fun app a lot and the true black BG option they have for phones with amoled panels makes it really easy to browse reddit for longer than I should be. It's also nice that when watching media on my phone with black bars on top or on the bottom that they are not lit up with a backlight and blend in with the bezels. I don't think I could use amoled on a laptop or desktop for the reasons you've mentioned, though.

Yeah. but the Purple smearing makes it terrible. watching movies or scrolling is just terrible.
There are positive things too. You can always keep screen on minimum brightness for clock and etc. AMOLED screens look better than IPS LED, their colours are brighter. I don't think that's bad technology as more and more smartphone makers are making transitions to AMOLED screens.
My moto x had an amoled display, and I loved it because of active display. There was pretty much no effect on battery life because of the amoled panel. Also, for those who prefer oversaturated colors, amoled delivers. Also, like it was said above

Using it at night with all black themes makes it much easier on the eyes imo.
But hey, to each his own

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 Google Pixel 2 XL'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!
Checked out the xl2 at verizon. Colors seems having too much black. Still has greenish color shifting in some viewing angle

Colors seemed washed out, much less vibrant than Note8. I will try to upload few comparison pictures later today

Yes couldn't agree more, my pixel XL 2 is so washed out I'm tempted to switch back to my note 8!!
Here are some of the comparison photos

Compared to a over saturated Samsung it probably does look washed out, in the picture posted, look at the hearts, the pixel looks red and you can see how oversaturated the Sammy is

Well in contrast, look at the beach on both photos. When I looked at both side by side, Pixel definitely lacked saturation in my opinion. I guess it comes down to personal preference but I never understood why people wouldn't like Samsungs saturation. Makes everything look much nicer, and if one wants to mute colors, there are a bunch of profiles in the settings as well as adjustments for individual colors. When you lack saturated colors like on this Pixel to begin with, you can't just bring more color out that easily.
The Verizon I went to had it setup with some preloaded messages, didn't actually get to see the OS and working screens. My comparison would be to the numbers the display is measured at, delta E, gamma, etc,... that is the only true measurement of color accuracy.
A similar post on Reddit mentioned that the Pixel 2 XL is set to sRGB mode by default, and that there was a toggle to make it more vibrant somewhere in the display settings. It would be interesting to see the same comparison with that toggle set to "On" with the Pixel (assuming that the info is good, and that the toggle exists at all).

That's true, there was a switch "Vibrant Colors" under Display settings but it was turned on at the one I checked
Google devices have been historically very accurate with the screen colors. Going from LG/Samsung will be noticable.

People tend to get that way these days because of the way televisions are sold with the brightness and color saturation practically maxed out. This results in super unrealistic colors that tend to offset your idea of what "good" is while killing off subtle image details in the process. Samsung seems to like to do the same thing with phones, perhaps based on the same mindset that their TV guys use: Make things flashy.
In the showroom it may boost sales, but when I take my TV home, the first thing I do is tone all of that down to make sure the color balance is more realistic. For example, I want grass to look like grass would be colored, not neon-green. sRGB mode on Google's phones is nice because it does that for you, without needing any color filters and test patterns.

YES. So. Many. Times. This.
I shake my head when I see people show off their new TV's with sharpness at 100 and vivid color profiles with bright colors and cool temp selected. More power to do what u want with your stuff, but it just looks rediculous.
As a photographer using calibrated displays and a Photoshop user, don't make up your mind on Webb posts. And I want a natural and sRGB.
Love the super saturated colors. This is coming from a normal consumer without any "expertise" in anything related to the subject matter. My eyes like it.
I despise the over-saturation Sammy does. This is good news to me.
This is funny because although I was only able to see the the Pixel 2 screen (non XL) I'm positive both will have great displays. I do like Samsung displays however I hate when the over saturation shows the absolutely wrong color. But not too long ago the Samsung S8 & S8+ displays had a red & purple tint on the white screen. And that was actually a very prevalent issue which was fixed by a software update. After seeing the Pixel 2 display I thought it looked good.
I have read that the display on the Pixel 2 XL has a bluish tint when viewed off angle and that the LG V30, which is said to have the same display as the Pixel 2 XL, has screen uniformity issues.
I went to my local Verizon yesterday to play with the phone and see for myself. The bluish tint off angle is absolutely there. It didn't bother me but it might bother some. As far as screen uniformity I didn't see any issues. At least not with the display phone. I tested with light gray and dark gray backgrounds at high and low screen brightness and I used my hands to block out room lighting as best as I could.
Color saturation looked good to me. A bit more saturated than my Nexus 5X I used as a side by side comparison.
The verge panned the v30 display in their review today. This isn't looking good

How white are your whites?

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

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

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

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

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

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

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

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