A place to ask your questions and seek help related to your Android device and the Android ecosystem.
Whether you're looking for app recommendations, phone buying advice, or want to explore rooting and tutorials, this is the place for you!
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.
