Both devices are IP68 dust and water resistant; and supports both fast wired and fast wireless charging.

The big, highlight is however the S9’s new camera system, which comes as a single lens on the S9 and a dual camera on the S9 Plus. Samsung says it has redesigned the phone with a new Dual Aperture lens that powers an innovative low light camera, Super Slow-mo video capabilities and personalized AR Emoji.

“The way we use our smartphones has changed as communication and self-expression has evolved,” said DJ Koh, president and Head of IT & Mobile Communications Division, Samsung Electronics. “With the Galaxy S9 and S9+, we have reimagined the smartphone camera.
