One of our reader was able to get an early access to the Samsung Galaxy S4 and extracted wallpapers from it for us. Download them from here and use them as wallpaper on your phone. Make sure to unzip it first on your computer and then transfer it to your phone. Alternatively, you can use an unzip utility on your phone itself.
The Samsung Galaxy S4 features a massive 5 inch display that packs full HD resolution. However, for some reason, Samsung‘s wallpaper resolution is not full HD. We checked it and it was 1600 x 900, whereas it should have been 1920 x 1080 – the actual resolution of Galaxy S4’s display.
