Samsung Electronics said on Friday that its operating earnings likely fell 56 percent in the second quarter from a year earlier.

The South Korean tech giant said in its public filing that its operating profit was estimated at six-and-a-half trillion won in the April-June period, a 56-point-three percent drop compared to the same period last year.

However, the figure would mark a four-point-three percent increase over the previous quarter and beats market expectations of six-point-06 trillion won. 

The firm's overall sales, meanwhile, are expected to have dropped four-point-two percent on-year to 56 trillion won over the three-month period.
