Google has announced a new version of the Samsung Galaxy S 4 during the opening day Google I/O keynote, which runs the latest stock version of Android Jelly Bean. This means that the specialized smartphone sports the Nexus experience. It's compatible with AT&T and T-Mobile LTE networks, completely unlocked. The bootloader is unlocked as well, and the device sports 16GB of on-board storage, expandable with a microSD card. One major benefit is the promise of immediate system updates to newer Android versions, thanks to the stock Android being used. Since the phone has no contract, it won't be cheap. The stock Android Jelly Bean version of the Galaxy S 4 will go on sale on Google Play on June 26th for $649.
