We informed some days ago that Samsung is currently working on successor of Galaxy S8, but it doesn't change the fact that Galaxy S8 had its premiere recently and it will be available in stores for a long time. Certainly this information doesn't make grieve heads of Samsung, because as show the latest reports Galaxy S8 sells in very large quantities.
How said one of Samsung's officials Galaxy S8 sells almost two times better than S7. This information says that Galaxy S8 had been sold in 10 million units during only 37 days. According to the latest reports Galaxy S8 may beat amount of 60 million sold units to the end of 2017.
