[Q] A serious problem aboout screen color

My GN screen like yellow when I show a white photo.I'm using a kernel who name is franco.
It looks better now.But, is it the only way to fix the screen problem?
Are there any better ways to fix the screen prolbem? I don't want flash this kernel just fix the GN screen problem.

If you didn't root your phone, just serch Screen Adjuster in market. adjust grey balance. it will be better. but you need to turn on manually every reboot.
the problem same as me, but I solved after root and adjust. pls see:

Are you using the franco.kernel app? Because it has color adjustments built in.

A lot of the Roms have that build in now as well.
AOKP and CM9 both actually default your color multipliers HIGHER than normal...resulting in a more vibrant screen. I don't know about the others.
So just flashing the kernel may seem to improve it...but it's actually a setting that is being changed by the rom.
For AOKP it's under Rom Control>Performance>Color Multipliers.
Hit the "default" button there...and it will restore to actual defaults.
As far as fixing without a kernel that allows color control...I don't think you can.
If it's that bothersome and you don't want to flash a kernel: replace the phone.
I think most (all?) of the modern kernels have color control enabled in them anyway. So if you're going custom; you might as well stay put with your device.

Yes,I'm using franco kernel app.And set color values.

Display Brightness between ROM's

Hi Guys,
Not sure if this is covered anywhere or if it's even an issue or maybe Percieved issue.
Between Flashing Cooked ROM's and Stock ROM's etc it always seems that the display while using stock ROM's doesn't seem as bright / vibrant - it always seems a bit duller at max Brightness, the Whites dont 'Pop' off the screen as much.
Is there any truth to this or is it just me? If it is the case what are the Chef's doing to make this so and can i do it to a Stock ROM?
Cheers
Paul

it can depend on 2 things
- kernel used -> some kernels disable or can disable "adaptive brightness" and modify color values
- the value set for auto-brightness in framework-res.apk. Most devs keep the standard values from google, I usually find them "too boring and dark" so i modify them.
So not your perception - you are quite correct

Ah thanks for the response. Though if i understand correctly this just affects the 'level' at which the brightness will be set at certain detected light levels on the Auto Brightness settings?
What i mean is that if i just go in and turn off Auto Brightness and slide it up to the Max - the Cooked ROM's always seem more vibrant and brighter.
Also is there anything that i'd be able to do to a Stock (rooted) ROM to get this extra Brightness?
Cheers

More details on this please?
Edit: nevermind, found it.

Mind Sharing Your findings MS? Or could someone else please help?

Here's something about content adaptive brightness:

You can turn it off with Franco's kernel app or with Supercurio's Voodoo display app, available in his thread here on xda.

Here it is. I had no chance yet to try it, but i believe it should work.

Thanks guys - went for Francos Kernel and can now adjust the levels with the tool

CM13 and sRGB

Hello,
I'm on OOS but would like to move to a CM based ROM, problem is I really like sRGB mode. The default is too crazy for my eyes and makes the screen look cheap. Is there a way to enable sRGB mode in CM based ROMs?
Cheers

They have livedisplay instead of sRGB / default stuff from OP. You can also tune yourself the color schemes.

As far as I know they are two completely different things: Live Display adjusts the tone of the screen, while sRGB sets the screen color space.
I'm no expert at all and still waiting for my unit, but I gather the results of these two features are be very different.

You may be right, but apparently CM will stay as is.

sRGB is good, slightly grey looking screen, but it's OK to look at. From the CM ROMs I've used the colours can still be a bit too vivid and wild.

Has anyone found a solution yet? I just flashed Sultan's CM13 which does not have sRGB build in. I can't stand the calibration without sRGB..

Just use any kernel that have KCAL control. And tweak your screen color, hue, sat, contrast, whatever to your liking
blu_sp*rk, boeffla, elemental, all has KCAL control.

how to tune the color balance on sRGB mod?

i can't stand the defult color.
but the screen seems a little yellow on sRGB mod.
any idea to tune the color balance on sRGB mod?

Yeah I m also looking for that it's not available in stock ROM may be a custom ROM could have this enabled

sRGB is the accurate representation of the colors, tuning it will defeat the purpose of using it. If you want the freedom to tune temperature of screen colors, you can always switch off the sRGB mode.
Tip: Use sRGB mode for a few days, you will get used to it.

You can use Light Manager (Pro) from the app store if it bothers you. The app is surprisingly effective at changing screen tint but I agree with what has been said; stick with sRGB for a while and you most likely won't want to go back to the stock 'neon' look.

U can install a custom kernel like bluesparks or elementalx which have kcal which will let u modify too ur liking, u need to be rooted and have trwp

I use kernel toolkit

I agree, sRGB mode is a bit too yellow...

Mine shows a very dark red. What to do? in general all colors seem much darker than they should be.
Light manger pro seems to be a program to change the led color?

i got the optimal settings
go to display & led -> livedisplay -> profile -> set this to photo
then to calibration -> set this to red 95%, green 93 % and blue 100 %
These are the best settings for me and i see no yellowish anymore

What program do you make these adjustments in?

No program. you can set this up in CM13.

Manually change color saturation, contrast, RGB, etc.,

5T comes with a few color profiles and last one where you can slide from cool to warn modes.
But the profiles I like the most, have too much saturation on colors.
Are there any option/non-root app to manually fine tune color/contrast/saturation?
If not, there are any root app to do this?
Regards!

Very good question I have the same trouble with profile colours that we can manage in Oxygen OS.

Any kernel that has kcal as a feature can fine tune colour using kernel aduitor
