Any AMOLED friendly redshift / blue filter apps?
I've use Twilight for years and love the red filter for using my phone at night. But since getting an AMOLED screen it's started to frustrate me. The way Twilight seems to work means that black also gets a red tint. Previously this was great, but on amoled black is completely dark with no back-light that needs masking with red. So by shifting it red, Twilight is actually making the screen much brighter.
Tldr: Any apps that leave black as black, but give a red tint to all the other colors?
You're viewing a single thread.
If it's not built into your OS, the only way is to root your device and load a custom ROM (or custom kernel with kcal support) which allows a red tint without affecting blacks. If you don't want to root your device then I'd recommend getting a secondary cheap/used device which is root friendly (eg Pixel or OnePlus) and then load a custom ROM on it, like LineageOS.
Can confirm. This is the main reason I miss having a rooted device.
