Another feature that we love on the Galaxy S6 is the ability to quickly change the theme of your phone. This feature is no available on the iPhone 6 nor is it available on some of Samsung's older Galaxy S/Galaxy Note smartphones.
You can use stock themes that Samsung provides or you can download themes from third-parties. For instance, we changed our Galaxy S6 to an Avengers theme right when the movie first came out. They look great and they're a touch on a phone that puts the customization keys in your hands.
