The Galaxy S4 is Samsung’s fastest-selling smartphone ever with shipments topping 6 million units in two weeks. Samsung co-CEO Shin Jong-kyun revealed on Friday that sales of the Galaxy S4 into channels will likely pass 10 million units next week, The Korea Times reported. The executive noted that it is selling much faster than the Galaxy S III, which took 50 days to reach the 10 million mark. The Galaxy S4 will hit the same milestone in less than a month.

Samsung’s latest flagship smartphone is equipped a 5-inch full HD display, a 1.9GHz Snapdragon 600 processor and a 13-megapixel camera. The device also includes 2GB of RAM, a microSD slot, NFC, up to 64GB of internal storage and a handful of unique features built into Android 4.2.2 Jelly Bean.
