Is anyone else not able to change the screen mode setting? I prefer the cinema setting but can't figure out why it's locked. Also the screen has been auto dimming and lighting up when the lighting in the room is low or high. Auto brightness is always off.. Had this issue on my first s6. It was replaced for other reasons. I also had this issue on a Droid turbo, Motorola said it was a built-in feature that can't be changed.
