Hello,
My eyes have a big sensibility to light, and they hurt my when using my phone, but in older versions, when I change the gamma settings I feel better, I was using this app "Advanced Color & Gamma Control‏", but this app is not working now, and it's written in its description: "NOTE: GOOGLE HAS DISABLED ALL modifications for GAMMA control!".
I tried using f.lux and other similar apps but they don't give the same results as that app I've mentioned (which changes the gamma settings).

So, how can i control the gamma options of my nexus 4?
i'm using now CarbonRom (Android 9.0).

Try installing kernel adiutor and see if that helps as mentioned in this post.

I'm doubtful as you mentioned that Google had disabled all modifications for Gamma control; but no harm in trying.

Then I don't think it is possible anymore. You'll have to live with that

I don't think it'll make any difference.

in earlier versions, i was using some kernels that have gamma control in their options.
I took a look in the available kernels in this forum, and i found some of theme which have the gamma control option enabled (mentioned in the kernel features), but they are all old kernels for earlier Android versions. so may be if i find newer kernel for nexus 4 which supports android 9.0 and has the gamma control options may be it will help, or may be it exists a method to enable the gamma control in the kernel that my ROM is working with.

Proably this patch, but nothing in userspace uses this since cm14, but if apps such as kernel aduitor still support this, @nitin.chobhe can maybe add it to his carbon rom kernel.

Thanks man! I'll pick this commit and test it before next Carbon weekly gets built (i.e. next Wednesday, 26 June 2019)

In the meantime you can try this kernel I compiled a while ago which also has gpu oc and undervolt support.
Use Smartpack kernel manager to set the gamma profiles.

@ARDV I picked the commit linked by @voron00 here: https://github.com/CarbonROM/android...6b785063300967

It should be in in tomorrow's weekly build. Once it is out, test and share your feedback
