The Galaxy S8 has crossed 5 million sales in less than a month, according to a report out of South Korea. An unnamed official from the company told The Investor (Korea) that sales are already beyond "5 million units," though detailed figures aren't going to be released yet.
They also said "sales are going smoothly around the globe."
If this report is accurate, it means the S8 and S8 Plus are selling faster than their predecessors. Samsung reported 7.2 million sales of the Galaxy S7 and S7 Edge during their first quarter of availability.
The actual sales figure might be lower than claimed, however, if the official is actually referring to "shipped" units.
Samsung has publicly stated the S8 series had the best pre-sale period of any Samsung smartphone.
