Samsung’s flagship Galaxy S5 handset is selling at a brisk pace, according to JK Shin, the company’s co-CEO and head of mobile. Since hitting stores early last month, sales of the latest model of the Korean tech giant’s flagship phone have crossed the 11 million mark, Shin told the WSJ this week. This means it’s selling faster than its predecessor, the S4, which sold about 10 million units in the same time period. “It’s been a month since we began selling the S5, and out of the gate, sales are much stronger than the Galaxy S4,” Shin told the Wall Street Journal.
