You are absolutely right!Thanks for your suggestion buddy but unfortunately it seems there isn't any ROM called Pixelish for Redmi 9s. Maybe you got confused with another device.
My mistake, I have 2 phones running in parallel.
This was about my old Davinci, I maintain it up to date.
Concerning Curtana I am satisfy with CORVUS V13.
From what I tested already it is the best available now. I guess up coming Crdroid V7.2 can also be a good choice.
Have a nice day.
