Yesterday reports from Korea suggested that pre-orders for the Galaxy S9 in Korea are 30% lower compared to the pre-orders of the Galaxy S8 in 2017. The Korea Herald, however, today says that Samsung believes it will sell more Galaxy S9 phones than it did with the GS8.
The Korea Herald says that Samsung told its suppliers that its target is to sell 43 million GS9 (and GS9 plus) phones in 2018. In 2017, Samsung shipped 41 million GS8 and GS8 plus phones. In 2016, Samsung shipped 48 million GS7 phones, so even if it reaches its target of 43 million GS9 phones, it will still lag behind The GS7.
The GS9 has a flexible 5.8" 1440x2960 (570 PPI) Super AMOLED display (6.2", 529 PPI, on the S9 Plus). DisplayMate says that this display is the best mobile display ever tested, surprassing in quality the 5.8" flexible AMOLED used in the iPhone X.
