Soon after Samsung unveiled the Galaxy S6 and S6 edge last week, its president Shin Jong-kyun revealed that pre-orders for the devices have already started “pouring in.” Now, a report from the Korea Times claims that Samsung has already received a total cumulative pre-order of 20 million units for the devices. Out of this, the Galaxy S6 received 15 million pre-orders while the Galaxy S6 edge received the remaining five million orders from “mobile carriers.” The pre-order number includes orders that Samsung has received from network operators from across the world, as well as direct pre-orders from consumers from regions where the new Galaxies are already available for pre-order. Samsung expects the Galaxy S6 to outsell its predecessor, the Galaxy S5, as well as the Galaxy S4 — its best selling flagship handset yet.
