Smartphone woes hit Samsung's Q2 profit

Samsung Electronics Co posted a second-quarter profit that missed analysts' estimates as the world's biggest smartphone maker lost market share.

Operating profit was 7.2 trillion won ($7.1 billion), the South Korea-based company said in a filing on Tuesday. That compares with the 8.1 trillion won average of 34 analyst estimates compiled by Bloomberg.

Mobile phone earnings will improve in the current quarter with a limited impact from a stronger won, it said.
