Electronics giant Samsung has said that profits for its first quarter are likely to be lower as smartphone prices fall.

The group said that it expects operating profit to come in at 8.4 trillion won ($7.9bn; £4.8bn) for the January-to-March quarter, down 4% from the same period last year and the second consecutive quarter that profits have dipped.

One of Samsung's biggest profit drivers in recent years has been the Galaxy range of smartphones, but this has been hurt amidst tightening margins and rising competition.
