Samsung Electronics says its first-quarter net profit rose 5.9 per cent from a year ago to 7.57 trillion won ($A7.85 billion), while operating profit declined for a second straight quarter.
The South Korean electronics giant posted operating profit of 8.49 trillion won - down 3.3 per cent from a year ago, following a 6.0 per cent decline in the fourth quarter.
Sales for January to March inched up 1.53 per cent to 53.7 trillion won, the company said in a statement on Tuesday.
The company - the world's top maker of smartphones and mobile phones in general - has been hit by slowing growth in smartphone sales in lucrative markets such as the United States and Europe.
The mobile business unit - which accounts for the lion's share of the overall sales - posted an operating profit of 6.43 trillion won - down 1.2 per cent from the previous year.
Global demand for both smartphones and tablet computers "decreased" in the first quarter, it said.
