Samsung Electronics said Thursday that its second-quarter operating income jumped 17 percent over a year earlier to the highest quarterly profit in more than two years, as strong sales of its Galaxy smartphones drove profit growth in the mobile business. 
In its earnings preview, the South Korean company put its operating income at 8.1 trillion won ($7 billion), compared with 6.9 trillion won a year earlier. 
That was much higher than forecasts. Analysts predicted 7.4 trillion won of operating income according to FactSet, a financial data provider. 
It was the best performance in nine quarters. The last time Samsung raked in more than 8 trillion won of operating income was during the January-March period in 2014 when it reported 8.5 trillion won in operating profit. 
Sales rose 3 percent to 50 trillion won. Samsung did not give its net profit or breakdowns among its business divisions.
