The only working as I expect is this app: https://play.google.com/store/apps/d....netmanslab.sa
- but it's rather annoying, asks form ma gps location, it's bloated with ads and also changes are lost after reboot (I need to enable it again). And most annoying - it blocks possibility to install applications from apk file.
So do you know any mod/app etc to adjust white balance (RGB)? It should start with system, it should be invisible.
