Samsung, the world's largest technology company by revenue, reported another record-high quarterly profit as customers flocked to Galaxy smartphones, helping it outdo rivals at a challenging time for the global tech industry.

Samsung Electronics Co. said Friday its net profit swelled to 5.9 billion won or 4.5 billion US dollars in the April-June quarter a 48 percent jump from a year earlier, on the back of a 47.6 trillion won revenue.

The result contrasts with rival Apple, which days earlier announced a 21 percent rise in profit that disappointed analysts.

In the second quarter, Samsung's mobile division contributed 63 percent of Samsung's entire operating profit.

Samsung, the world's largest maker of mobile phones, televisions and memory chips, benefited from runaway demand for its Android-powered smartphones as rivals including Apple Inc. were yet to release new models.
