“Although the Galaxy S9 may not have the innovative features expected by the market, we are focusing on enhancing the completeness of the Galaxy S8 hardware and an innovative user experience (UX),” a Samsung said all the way back in mid-November. More and more Galaxy S9 reports were painting a similar picture at the time. The Galaxy S9 would not bring over a brand new design. Instead, Samsung would repackage the Galaxy S8 with new hardware and software tricks this year.
Fast-forward to today, and you’ll see a rumor that says Samsung invented new UX features for the phone never-before-seen on previous Galaxy S models.
