If confirmed, it would mean Galaxy S4 sales are approximately 1.7 times faster than sales of Samsung's previous Galaxy S III at the same point in the product life cycle.
Samsung revealed back in May that it had shipped 10 million Galaxy S4 smartphones globally, less than a month after the smartphone was launched.
