As you know, Samsung launched the Samsung Galaxy 3 III internationally with model number GT-I9300 and a quad-core Samsung Exynos chip with 1GB RAM. The U.S. variants get an upgraded 2GB of RAM, but the processor gets swapped out for the Qualcomm Snapdragon S4 because of LTE and AWS compatibility.
Wouldn’t it be great if we could combine the two phones? Korea is expected to get a new version of the Samsung Galaxy S III in July that does just that. It packs the same Exynos quad-processor and 2GB of RAM. Other than being a little thicker (9.0mm as opposed to 8.6mm), the rest of the specs will be the same. Looks like they just one-upped the LG Optimus LTE 2.
