Earlier today we reported on alleged leaked photos of the Samsung Galaxy S4, or according to the model number in the photos, the GT-i9502. While it remains to be seen whether that device is indeed the Galaxy S4, the folks at SamMobile have confirmed that according to their sources, the Galaxy S4 will launch with a dual SIM version which will be known as the Galaxy S4 DUOS. This alleged dual SIM version will be available only in China for Chinese carrier, China Unicom. Apart from that added dual SIM feature, we expect that the rest of the device should be the same, which according to the rumors will come with a quad-core chipset, 2GB of RAM, a 4.99” Full HD AMOLED display, a 13MP camera and Android 4.2 Jelly Bean running the show. Either way we guess we will have to wait until the 14th of March before all is revealed, so check back with us then for the details!
