Speaking with the Korean Times Samsung Electronics co-CEO Shin Jong-kyun said that the Galaxy S4 is on track to achieve the 10 million units sold milestone by next week. If this turns out to be true, Galaxy S4 would be the fastest selling smartphone in Samsung’s history considering that the Galaxy S3 achieved the 10 million units sold mark in 50 days and managed to sell 20 million units in 100 days.

Considering the US market, users are able to pick up the S4 but, it is still not available through Verizon. This may very well change in few days time as Samsung’s flagship device is expected to arrive on Verizon on May 23. If this happens, Samsung will be well over the 10 million mark.
