I recommend you to download this picture of curve lights 01 for your Samsung Galaxy S7 and S7 Edge. As one of 11 other similar wallpapers, this wallpaper was especially created in 1440x2560 pixels and perfectly matched for Galaxy S7 and S7 Edge. You know that S7 and S7 Edge are also designed with 1440x2560 resolution. Samsung Galaxy S7 has a 5.1-inch screen size. While the S7 edge has a 5.5-inch screen size. But all of them need a picture with 1440x2560 resolution for changing their background.
