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).
