Android app icons sit on the homescreen of the Galaxy S9 smartphone during a Samsung Electronics Co. ‘Unpacked’ launch event in London, U.K., on Thursday, Feb. 22, 2018. The South Korea-based technology giant is banking on new features such as augmented reality-based emojis, camera upgrades, and stereo speakers in a form-factor similar to last year’s model in order to take on Apple Inc.’s iPhone X.

Light or dark, Samsung’s new flagship smartphones sport cameras that stay sharp in any situation.

At the Unpacked Event 2018 in Barcelona, Spain, Samsung unveiled its first smartphones to feature dual-­aperture lens – the flagship Galaxy S9 and S9+.
