The company went through familiar motions, but the usual buzz and excitement for its new flagship phone weren’t really there. Thanks to the toxic mixture of incremental upgrades relative to the existing Galaxy S8 and the usual pre-announcement cycle of leaks and revelations, there just wasn’t much to get hyped about. Unless you liked those creepy AR Emoji. >The one source of solace for hardware geeks came in the form of Samsung’s new dual-aperture camera system in the S9. Not since 2009’s Nokia N86 has the world seen a phone with variable aperture, and Samsung’s revival of that feature did stir up some interest. For me, it was the thing that salvaged the S9’s launch, and the thing that protected this new device from even sterner critique from fans hoping to see more aggressive upgrades from Samsung.
