Just how much does that new Galaxy S5 cost Samsung to assemble? Well, according to IHS, just $256. Yep, that's the BoM for the new Samsung Galaxy S5, the same device that costs $699 ($599 in select regions) unlocked. Of course, BoM doesn't factor in R&D costs, among others. But this way, we still get a good idea on just how much profit Samsung is making on the sale of every Galaxy S5 handset.
