According to The Korea Times, a Samsung executive said that the company now expects to sell more than 70 million S6 and S6 edge units. It's not clear if this is Samsung's goal for 2015 alone, but, even if it's not, the company should have a great year thanks to the two new flagship smartphones (which are available to buy around the world since April 10).
The Korea Times further notes that Samsung Vice Chairman and CEO Kwon Oh-hyun declared that the first week of Galaxy S6 sales "looks impressive."
As reported a few days ago, Samsung is surprised by the success that the Galaxy S6 edge is having. This means that the handset (which is $100 more expensive than the regular S6) may be hard to find in the next few weeks, or maybe months, until Samsung manages to manufacture enough units to meet the high demand.
In the last quarter of 2014, Samsung's global smartphone market share dropped to a 3-year low, while Apple took the crown as the world's largest smartphone vendor. This year, Samsung is clearly doing better than in 2014, so it might regain its lost market share. But we'll see what happens when 2015 ends.
