On the outside, the U.S. and African/South Korean versions of Samsung Galaxy S4 look alike, but on the inside, there are major differences in key components.This came to light through a physical dissection of the devices conducted by the IHS iSuppli Teardown Analysis Service.Excerpts of the report, published by Cellular News indicated the differences include the apps processor, the wireless subsystem and the user interface, adding that all of the permutations resulted in significant variations in the capabilities and pricing of the two versions.“While the Korean/African and US versions of the Galaxy S4 look pretty much the same and have in terms of their core electronics many same core features such as the enclosure, display, camera and battery, the products are as different from each other as kimchee and coleslaw," said Vincent Leung, Senior Analyst, Teardown Services at IHS.The US version of the recently launched smartphone has 16 gigabytes of internal flash memory and carries a bill of materials (BOM) of $229.00, which rises to $237.00 when the manufacturing cost is added, while the Korean/African edition with the same memory has a BOM of $244.00 and a combined manufacturing and component cost of $252.00."With at least four different known incarnations of the Galaxy S4, Samsung is demonstrating its strategy of offering a mobile product that has appealing features and pricing to suit the tastes of varying markets or regions," Leung saidLeung also stated that Samsung’s approach is in stark contrast to the one-size-fits-all philosophy used by Apple, Samsung's primary competitor in the wireless space.
