I have a lot of wallpapers for smartphones, all of them are designed in high quality and can be an alternative for customizing your phones. Such as this one,a picture of galaxies over the mountains. This picture has a resolution of 1440×2960 pixels. I use this wallpaper as the background of Samsung Galaxy Note8. As we know that the Galaxy Note 8 has a resolution of 1440×2960 pixels and has 6.3″ screen size.
