I use this picture of curve lights 10 as one of 11 similar wallpaper for Samsung Galaxy S7 and S7 Edge. This wallpaper was especially configured in 1440x2560 pixels resolution which perfectly matched for S7 and S7 Edge. The S7 has a screen size of 5.1-inch and the S7 Edge has 5.5-inch. So, both of S7 and S7 Edge need a picture with the resolution of 1440x2560 pixels for their wallpaper.
Furthermore, it's free to download all the collection of artistic curve lights wallpaper for your S7 and S7 Edge on below gallery:
