As for the processor units, smartphone has an 8 core SoC Sxynos 5 Octa 5410, which has four Cortex-A15 cores, and 4 Cortex-A7 optimized for lower power consumption, while the graphics processor is PowerVR SGX 544MP. All this runs on Android version 4.2.1.
By appearance Galaxy S IV a lot (maybe too much?) similar to the Galaxy S III, but perhaps this is both misleading because there are sources that claim that it is in fact a model named Galaxy DUOS, and they are pretty reliable. Anyway, what is happening is exactly what Samsung desires - the emergence of a lot of assumptions from "reliable sources" while we wait for the "big" event - the final official announcement of the appearance and technical features of the most prestigious smartphone from their offer.
