It's a great idea to customize your Samsung Galaxy S7 background with this 3D diagonal lines wallpaper. I call this the Diagonal Lines 2, one of my best selection wallpaper for both Galaxy S7 and Galaxy S7. It's featured with special resolution which perfectly matched with both of them. As we know that S7 comes with 5.1-inch screen, while the S7 Edge has 5.5-inch screen size. Both of S7 and S7 Edge need a wallpaper with a resolution of 1440x2560 pixels.
