Samsung's smartphone business is still struggling, but the company as a whole has reported high profits for the third quarter, resulting in a share value jump. The estimated $6.3 billion in profit for the quarter was higher than analysts had expected. Samsung's shares rose 9% following the announcement.

The increase in profit is partly due to current currency exchange rates and the increase doesn't mean Samsung's key phone business is doing much better. Instead, it is likely component sales were stronger during the quarter.

Final earnings figures will come out later in October and at that point we will see the breakdown of Samsung's earnings by division. It is expected we will see increased profit from processors and displays, but a decrease in profit from smartphones.
