Yellow tint/Green tint Brightness Issue Fix (Exynos Only)

[Suraj fernando]

Many Galaxy devices have a Serious issue.
You can't adjust brightness and your display is greenish and not usable.
After many years of hard work and researching.
I found the best and free method to fix this issue

The world first solution without replacing the display.
This will help you to get a 100% usable display.
I spent lot of hard time for this.


Today I will show how to fix this issue by flashing a custom ROM and some small stuff
- There is a way to use Samsung stock roms but it's not stable if anyone interested in that please let me know I will help -

First of all your device must be the Exynos model

1) Install TWRP

2) Make a EFS backup (very important)

3) Download and install (flash) any Aosp ROM,
(Evolution x ROM recommended)

4) Root your device (if ROM already have Root you're good to go)

5) Download Color changer pro & pwmfree Apk files (can't provide download links for color changer pro because it's a paid app you can find it somewhere on internet for free) Asop roms doesn't limit maximum brightness but Samsung roms does. So after flashing aosp ROM you can easily bypass display flickering issue by setting brightness to maximum amount easily by brightness slider top on notification panel.

6) (VERY IMPORTANT) install PWMfree and give notification permissions and display overly permissions.
- DON'T USE YOUR DEVICE AT MAXIMUM BRIGHTNESS WITHOUT USING THIS APP !
This app helps you to decrease amount of brightness by adding a black overly on your display it's working like your adjusting screen Brightness.

7) after installing color changer pro and open it you will ask Root permission and there will be a custom 1,2,3 tabs touch and hold to edit values my best adjustment is R: 239 , G:238 , B: 255 , S: 1.00
And it depends on your display and your choice just slowly play with it till you get the best results and make sure you save the values

Enable developer mode and set all animations to off this will help when screen is dimming while screen timeout.

"Every time you reboot your device it's adjusting the brightness auto and fix itself (pwmfree)
But after every reboot just open color changer pro and select your custom mode it's only need to set if you only reboots"

- There is a way to use Samsung stock roms but it's not stable if anyone interested in that please let me know I will help -

That's all your device is so much better than before
Thanks me later..

No need to install anything, its hardware issue not software issue.

Only reliable fix is to turn on AlwaysOn to always show, let it go to normal color after locking display and wake it with press on home button not a hardware button, works like a charm.

Without installing any third party apps with suspicious wakeups and logs.


No hard feelings tho.

brother every display is not the same
your display is not hardly damaged

And the issue is the display flex cable this method will work for same devices but not for all devices i have played with this for 4 years and you are correct if the display is not hardly damaged.

I can show you if there is a doubt about it because i tried your method long time ago its worked for Galaxy note 10+ but didnt worked for galaxy s9 plus & note 9 but worked for another note 8.

If your method didnt help this is the last method you can try other than rreplacing the display flex cable (our country there is no place to replace the flex only opinion is to replace the display)
