Samsung Electronics is expected to achieve its best quarterly results ever in mobile phone sales in the second quarter of this year.

Following record sales in the first quarter, it is expected to earn even better results in the second quarter, Shin Jong-kyun, the head of Samsung's mobile communications business, told reporters Monday. "In just about a month after the release of the Galaxy S3 in the global market at the end of May, sales are expected to exceed 10 million units."

The division is expected to break the records set in the first three months of this year, when it achieved sales of W23.2 trillion and operating profit of W4.3 trillion (US$1=W1,163). Second quarter sales are estimated at W25 trillion and operating profit at W5 trillion.

The achievement is likely to further consolidate Samsung's position as the world’s No. 1 mobile phone manufacturer. In the first quarter of this year it sold 93.5 million handsets, including 44.5 million smartphones. Smartphone sales are expected to surpass 50 million units in the second quarter.

Overall earnings at the company in the second quarter are also forecast to surpass the record set in the previous quarter of W5.85 trillion. In the memory chip business, DRAM prices recovered early in the second quarter, and in the non-memory market sales of smartphone application processors have been brisk. As for the TV division, the impact of the eurozone crisis is the main variable.
