Having used a similar approach for the launch of last year's Galaxy Note 8, Samsung has today released a handful of new teaser videos for the Galaxy S9 and S9 Plus on its South Korean YouTube channel, with the short flicks focusing on the photographic capabilities of  the upcoming flagship handsets. 

In the first of three videos, each lasting only 15 seconds, Samsung fires off a series of fast-moving, rapidly-edited action shots featuring a skateboarder, a roller-coaster, a wingsuit pilot and more.
