Samsung knew that the Galaxy S8 lineup would achieve high demand, but not many people thought that pre-orders for the smartphones would surpass its predecessors. According to an email sent by Tim Baxter, the President and COO of Samsung Electronics America, the Galaxy S8 and S8 Plus showed "more than 30 percent year-over-year growth in pre-orders versus the record pre-orders we had with Galaxy S7."

He didn't reveal the exact pre-order numbers, but Samsung must be happy with those numbers, especially after the incident they had with the Galaxy Note 7.

Separate report says that the larger 6.2-inch Galaxy S8 Plus will sell better, ending up with 53.9 percent of the total sales of both phones.
