An unnamed Samsung exec hinted to the Korea Times that its upcoming flagship, the Galaxy S III, will include a next-gen quad-core Exynos chip that will incorporate LTE and WCDMA radios. Of course, such a revelation shouldn't come as too much of a surprise since both its predecessors were built around home grown silicon… at least originally. According to the source, Sammy is trying to become more self-reliant and distance itself from Qualcomm which has provided single-chip solutions for a number of the manufacturer's high-end handsets.
