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 1440×2560 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 1440×2560 wallpaper.
Furthermore, feel free to collect all my collection of artistic curve lights wallpaper for your S7 and Edge on below gallery:
