I use this picture of curve lights 06 as one of 11 similar wallpaper for Samsung Galaxy S7 and S7 Edge. It was featured with 1440x2560 resolution which perfectly matched for S7 and S7 Edge. As we know that The S7 and S7 Edge are configured with the screen size which needs a 1440x2560 wallpaper.
Furthermore, feel free to collect all my collection of artistic curve lights wallpaper for your S7 and Edge on below gallery:
