Samsung has managed to sell more than 11 million units of its flagship Galaxy S5 smartphone.

The phone launched in April and the figure, revealed by the head of Samsung’s mobile business J.K. Shin, indicates that it is selling faster than its predecessor. The Galaxy S4 hit about 10 million units in the first month of sales. 

According to the Wall Street Journal, Shin believes strong sales will help boost margins and Samsung’s smartphone market share.

"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 is quoted as saying.

Although the S5 is selling well, not everything is going well in the house of Samsung. The company got a lot of flak for failing to include groundbreaking features in the S5 and it was criticised for its decision to keep using an all-plastic body. Just last week Chang Dong-hoon, the head of Samsung’s mobile design department, resigned. It is claimed that his resignation was prompted by the poor reception of the S5 design.
