Samsung has listed a Galaxy S III variant on its Chinese website. Identified as GT-I9300I, Samsung will market it as Galaxy S III Neo+. The few differences from the regular Galaxy S III we could find is the support for dual-SIM connectivity (3G + GSM) and Android 4.3 out of the box. As for the rest of the features, the Galaxy S III Neo+ has a 4.8-inch HD (720p) Super AMOLED display, 1.4GHz quad-core processor, Bluetooth, Wi-Fi, GPS, 8MP camera, microSD card slot and 2100mAh battery.
