Tech Brief: Samsung Announces Galaxy S9/S9+

As Google prepares to assert its dominance over Android, Samsung took to Mobile World Congress to unpack its flagship Galaxy S9 smartphone today for a price tag of US$ 720/840, packing an upgraded variable aperture camera (capable of switching between a very bright f/1.5 to a smaller f/2.4 depending on exposure conditions) and its own take on Apple Animoji (called AR Emoji) in an otherwise familiar body that the Korean electronics chaebol embraced last year to much critical acclaim. After all, why fix something that isn't broken!
