[Q] LG G3 (T-mobile) Screen colors different - G3 Q&A, Help & Troubleshooting

I've recently purchased 2 LG G3 from T-mobile and strangely, the screen colors on those two appear to be quite different? (one seems to be warmer and sort of darker, I have two screen at the same brightness level)
The easiest way to tell the difference is to pull out the setting screen where there are menu options in white background, the colors on the white backgrounds are clearly different on two devices. I've also tried to compare the two I have with another G3 in T-mobile store, and the 3rd one doesn't have the same color to any of mine G3's. The color adjustment settings on all 3 devices are OFF, I've tried to factory reset the devices I owned but nothing changed. Anyone notice the same issue with your G3?
Also I notice there's a code on the back of the back cover of the G3, does that code represent anything? Is it okay to swap the back covers of the 2 G3's with same model?
Thanks

That's just the QC tolerance from what I understand. My korean G3 has warmer colors while my D850 has cooler ones. You can swap back covers without any issues so don't worry about that. Anyway back to the displays, you can download an app to adjust the color tone. At the end of the day it's just how that particular display is.

Thanks for your reply.
Yeah, I've never had a chance to compare two devices with the same model. I've always expected them to have the same exact screen colors.
Could you point me to some apps that can adjust screen color tone? The Color Adjustments setting under Accessibility setting menu is just for contrast, right?

Trickster mod if you are rooted is a good one. Just search the play store for it there should be quite a few out there.

Trickster Mod color-settings, Intensity

Hi forums,
TL;DR: Could turning up the color-settings in TricksterMOD cause burn-ins?
I recently got my GNex and after fixing the SIM-tray making the phone usable again I of course unlocked the bootloader and flashed ROMs and Kernels (atm CM10.2 latest nightly + Franco kernel) and I use TricksterMOD to make some specific settings (like turning FSync off) and I also found Settings for screen colors, now what I did is just turn those sliders up all the way and set all other options (like Contrast and Gamma) to 0 (as seen on the attatchment), now I have an extremely vibrant and colorful display without this annoying blue-tone everywhere, even whites look more natural now but I've seen some AMOLED-Phones (specifically 2 GS2s from friends) that have things like the Status Bar or the keyboard burned in into the Display and now I worry that that could maybe happen to my Phone as well because of the settings.
I'd like to know your experience and if you think that that's possible, if so I'll turn them down even though I really really love this display now, it's literally the best display I've ever owned (and I have two IPS Monitors in front of me right now)
I'm using a completely black theme over most of the Phone (black status bar of course, black keyboard, black menu-elements, dark backgrounds, saves Battery and looks insanely awesome on this display) that should prevent burn in's from for example the keyboard since black pixels are not lit, but I want to know if it's more likely if the display is brighter due to the settings.
Sry for this long post but you've got the short version at the top if you don't want to read everything
Thanks for your time and help in advance!

Adjusting screen's bluish tint

Has anyone figured out how to adjust the screen tone to make the screen appear less of a cool or bluish tone? Coming from another more color accurate LCD device, the blue tone instead of white bugs me.

Care to elaborate further? I just tried the different options listed under the Vision menu, none of them had any impact on the blue tinting.

Tap it and it will show a picture of jelly beans or M&Ms or something. Think of it as a grid. Center is the neutral zone.
However this will NOT change the color the white balance, only the gamma of the colors.
My LG G Tab X8.3 has a high red HUE. Comparing the G4s blueish tone against the X8.3s redish tone, is horrible. I prefer the softer bluer tones. There is an app in the Play Store to actually adjust the colors, but it is basically just an overlay. It caused me lots of lag, delay, missed touches, etc.
A custom kernel is the only way to properly adjust the LCD colors on a low level, without an app.
Actually My G4 H811 has Screen Mode hidden in settings but it does not make any effect. I wish it works on other models or at least on the rooted H815. To enable hidden feature, Need to create a Widget with Nova launcher a choose Activities. Then scroll and expand Settings and look for Screen Mode.
Gotcha thanks. I'm debating on trying this phone again, my S3 died and honestly I've had way too many uniformity and inconsistencies with AMOLED displays, so I want to stick with an IPS display. I've been using my old iP5s and I can't stand it, I need to get something ASAP. Just wish I could bring the white balance back to a neutral white, then maybe I'd be more content with the phone.
That... and better gaming performance.

Tiny contrasting/sharpening outline around text & icons on new D852?

So i just picked up a G3 today and there's one thing that is bothering me.
All the outlines of icons / text seem to have a minuscule but detectable contrasting outline around them. It's hard to describe and kind of nitpicking, but my eyes do see it especially with text overlayed on a color or image background. It's almost like a tiny oversharpening effect and I've never seen it on other phones before. What is this? Is it due the layout of the subpixels? Also I noticed the color balance is somewhat yellowish. Is there a way to fix these problems? perhaps through custom roms? Would scaling down the resolution to 1080p make a difference.
Detailed example: I put my new G3 and Asus zenfone 2 side by side, and looked at their chrome icons (the exact same icons) through a magnifying glass. On the zenfone's display the line separating green and red in the icon transitions smoothly and normally- from green to red. But sure enough, on the G3, the magnifying glass reveals a tiny whitish line between the green and red areas! Therefore the change in color does not transition smoothly, which is what my eyes are picking up on. How to fix this problem?
If this is just inherent to the display itself I may consider picking up a Oneplus X instead, as it is somewhat irritating for my eyes especially when reading text.
This phone has a problem with oversharpening most custom roms have it fixed a lot of people complained about it u can reduce screen to 1080 but then u take away from the beuty of the screen if u decide to keep it root it then use a cust rom and itll be all good
If u have custom recovery then u can flash oversharpning fix mod.

I recently cracked my screen and replaced it. Now brown is where black should be.

Details about screen and for context
The the last screenshot of notification panel is on dark mode, the panel should be black but its brown/grayish.
The 2nd one shows the black color (just for comparison)
I replaced screen from a 3rd party. The service is legit.
First thing i noticed is that , the screen calibration has been stuck on which seems like default color profile. There is no visible change when i switch between sRGB , Soft and Default. Custom does work as intended (add blues and yellow when i move slider).
I contacted the service i used and they have been very vocal. They have no idea what it is. I'm guessing something with color profiles issues. Hoping you would help me solve this mystery. Also any idea to get the screen calibration unstuck on a single profile. Thank you.
Will update post with more info if asked.

Question wash out/fade across the top of the homescreen display

So ever since I have had my 6 pro I notice that when I have a black wallpaper or a dark colour set the top last maybe centimetre from across the top of the display washes out/ fades out Into grey and I have noticed that changing between different colour profiles either makes it less apparent or more worse. I'd like to think it's software as I don't think it's doing it anywhere else but the home screen but I could be wrong.
I think this is a thing to show the QS panel, we had a bug on the betas where there was a line up at the top of the screen to show it too. IIRC that one occurred only on lockscreen though.
That's actually part of the pixel launcher. I hate it with a passion. My mod, which is available now, removes it by default. If you are not rooted you have to use a 3rd party launcher. If you are rooted but don't want to use my mod you can edit the image. Its called workspace_bg.9.png.
