Maybe we could have a generic tips and tricks thread for the S4?
Tip: If you want the Jellybean logo on your wallpaper, go to Settings -> More -> About device, and tap multiple times on the Android version. After 4 or 5 times, the jellybean image will appear overlayed on your current wallpaper with your current JB version. The text disappears after a couple of seconds and you can take a snapshot; then use that as your new wallpaper!
