Samsung sees record quarterly profit on smartphone sales

Samsung Electronics has estimated that it will make a record profit in the October to December quarter.

It expects to make an operating profit of 8.8 trillion won ($8.3bn; £5.1bn) for the quarter, a 90% jump from the same period a year earlier.

That would make it five consecutive quarters of record earnings.

As the BBC's Lucy Williamson reports from Seoul, the success of its Galaxy range of smartphones has been a key driver of Samsung's growth.
