Hi, i have a z1, and in general, i'm very happy with it. But i have a friend with a galaxy note 2, which my screen should easly be able to beat, but he can change his "screen mode" to dynamic, and all of a sudden, he gets way better colors. So i'm wondering, is this possible to do on the z1? This clearly is an os thing that should be possible, and if it doesn't have this built in, is there an app that changes this? I have a rooted device. Thank you!
