With the Group Play feature of the Samsung Galaxy S4 you can share music, photos, documents and games with other S4s without the need for a Wi-Fi or even a cellular signal. You can even share music with other Galaxy S4s in real time, so you can all play the same song at the same time.
It lets you share super easily! You don't need to set up Wi-Fi connections or pair via Bluetooth, you don't even need reception, and you can share almost anything you want just by bumping Samsung Galaxy S4s together. Videos to friends, photos to friends, you can even play multiplayer games by bumping the two phones to sync them up. At a party or fancy some surround sound music? Just bump a few Galaxy S4 phones together and you have surround sound speaker smartphones. Creating your own party atmosphere just got easier.
It works via NFC technology, which is a wireless technology that works over short range. Access the file you want, select the Group Play option and bump your S4s together. It's as easy as that!
