Samsung is known to churn out variants of its existing devices and the new one to the list is Samsung's 2012 Galaxy S flagship – Galaxy S III. Samsung has listed Galaxy S III Neo+ variant on its Chinese website, which is similar to the original device but with some modifications.
Biggest change is the support for dual-SIM connectivity with dual standby. It also comes with Android 4.3 pre-installed.
Apart from these two changes, we're looking at the same Galaxy S III with a 1.4GHz quad-core processor, 8 megapixel camera, 4.8-inch Super AMOLED display, Wi-Fi, Bluetooth, expandable microSD memory card support and 2100mAh battery.
