The Korea Herald got the data from three major Korean operators coupled as official sales partners SK Telecom, KT and LG Uplus. More details, the Samsung Galaxy S9 sold 479,000 units in March and only 231,000 units in April.
Informers from one of the local operators whose identity covertly argued that sluggish sales are due to no significant increase or new features offered by Samsung Galaxy S9, plus the price is also quite expensive.
This is reinforced by data calling the Samsung Galaxy S8 in the same period last year ie two months after available in the market is able to sell reached nearly one million units.
The same condition is reported also happened on Apple iPhone X in Korea. After launching in November in South Korea, iPhone X only sold 475,000 units in the last four months, even in February alone selling only 70,000 units.
