More than half of the profits can be attributed to the semiconductor business, while the mobile department contributed with about $2 billion of profit overall. That loot comes on the back of 90 million phones and 8 million tablets shipped, with the average selling price for phones registering at about $180, and profit of $24 per unit on average.
This means that Samsung's profit from a phone sold trails Apple's significantly, which can be expected given that it also sells million of J-series and other low-end models, too. The reason Samsung sold so many phones compared to the 72 million in Q3? Well, "the mobile business saw its earnings increase year-on-year on the back of continued robust sales of the flagship Galaxy S7 and S7 edge, as well as improved profitability in the mid-to-low end segment." There you have it, all those S7 and S7 edge phones that went as replacements for the Note 7, or as its Blue Coral alternative, haven't been shipped in vain.
