Is there any possible way to adjust screen gamma with just root? I remember on my gnex I needed a custom kernel to do it, but I'm hoping there's a way to do it without changing the kernel.
TIA!

You would need a custom kernel.
:'( I can live with it for now - the "dynamic" setting is the best I'm going to get I guess.
It's really surprising to me that no smartphone or even tablet displays (that I know of) have contrast/gamma/hue/etc settings... ???

Do u know a root or not root app that does the negative of what u see on the screen?
Don't know about inverting colours but I know you can change them.
If your using cyanogenmod or something based on it try render effects in cmsettings.
Otherwise try this.

Hi all,
I don't own an S5 as yet so I can't test this myself. I've been looking around and noticed a custom kernel mention an option for LCD Color Control. I am wondering, does this mean you will be able to alter the color temperature (white balance) of the screen? The kernel where I've seen this is [KERNEL][GPL][3.4.91+][SM4.10]Blaze™ Kernel -15. Are there any other kernels which allow color control?
Thanks.

Yup, Ktoonsez kernel can also change the color temp :good:

Theres also built in applications that allow you to alter the screens appearance. (Try looking in the Display settings)
Thanks guys,
I was aware of the in-built display settings but I wanted something that allowed finer control.
Ok, I've got my S5. I'm going to give the LCD color a try soon. I was just wondering if anyone has actually tried this and altered the white balance? I find the whites a bit too yellow.
I bought a new Note 3 a week ago, it`s the black version, made in Vietnam, selling in Europe.
I`ve compared it to 3 other Note 3 devices and the colors on mine are way off.
The display is evenly lit, but it has a somewhat greenish/blueish, sometimes yellowish tint on the whites and the resulting picture is unbearable for me.
Any possible way to gain more control over the display`s calibration, so I can try to fix this?
Thanks in advance!
That depends on the rom and kernel you are using.
On Samsung Stock you may try Settings -> Device -> Display -> Screen Mode and test the options.
On the DU AOSP rom you may change color temperature in Settings -> Device Specific -> Screen -> Color Temperature.
Some Rom / Kernels will allow you to fine tune the basic colors.
Unfortunately, the stock rom doesn't provide control over white ballance.
Changing the color temp doesn't seem to fix the problem either - i tried it with the app "Lux".
I guess fine tunning a particular color is the way to go, but so far i do not know how to do it.
Could you please name a suitable ROM/Kernel, that could offer this option?
Thanks

You can tweak the basic colors on Samung phones changing MDNIE parms.
Use Faux123 Kernel Enhancement Pro
Fauxclock will only show the MDNIE Controls menu when rom/kernel supports it. Try it on your rom first.
It works on [Rom][4.4.4][Team D.I.R.T] Dirty Unicorns. Should work on most AOSP roms.
Finally, i decided to Root my device and paid for Faux123 Kernel Enhancement Pro .
Unfortunately, there are no MDNIE/Gamma /Color controls present in the menu.
Could it be the ROM/Kernel?
Mine are:
Kernel - 3.4.0 - 1937874
ROM (stock) - JSS 15.JN9005XXUDMJ6
I don`t want to install custom ROMs, because i wnat to keep the Knox counter at 0x0 and keep my warranty.
Please, help.
Thanks!
You can't calibrate the colours with stock kernel/Faux Clock unfortunately. Custom kernel or tripped Knox

So I won't be able to try to fix the issue without breaking warranty.. Unfortunately this doesn't work for me.
Next step - samsung service, although i think they will laugh at me about this kind of issue.
Thanks all for the support!
Ok, there`s no way I will get a replacement from my carrier, in my country they`ll do everything possible to reject warranty service.
Could you please suggest a custom kernel that supports MDNIE control?
Thanks.
I have flashed Frankenclark kernel then dled Ex kernel manager.
I don't know what to tweak in this kernel.
When i enable High brightness mode it enables but sometime after when i open it is Disabled... let me know if its not supported or i have to check something to get it permanently enabled.
Also i want to increase blue tint little bit but i am not getting proper settings in advanced color control.
Somebody please let me know how to use the settings and tweaks

It turns off when you turn off the screen. It's shouldn't be on all the time, it's way too bright. Check out the widget in my signature if you really want it to stay on all the time.

It got fixed now and is enabled and working even after reboot, i just ticked on right icon and reboot... loving it so much now and screen is looking more awesome and brighter than before and i don't even have to set it to 50%... its on 30% now and is way better than many other screens.
If i even increased it to 50% for movies and games it looks perfect awesome :good:
Anyway thanks for the reply.

thats how i did it. changed mine to 320 with no significant issues yet, and the guide was fairly easy.
what is standard dpi of a zmax pro, and if known, any safe alternate value(s)?
They all work for me as long as I disable the lockscreen notifications. If not it gets stuck with the screen flashing. I have fingerprint lock no notifications at 400 dpi. Works great.
