We've known for a while that Samsung is set to announce new devices on February 25 and we're almost certain those devices will be the Galaxy S9 and Galaxy S9 Plus, and now we've heard word the phones will be on sale by March 16.

A new report from South Korea (and cited by The Investor) claims both of the phones will be ready to buy under three weeks after the MWC 2018 launch.
