Samsung’s latest flagship phones restore a couple of popular features dropped from the previous generation, the BBC reports.

The Galaxy S7 and Galaxy S7 Edge both accept MicroSD cards, allowing their storage to be expanded, and can also be submerged underwater.

In addition, they feature new gaming tech and a rear camera that should cope better in low-light conditions.

Their overall design, however, is similar to the Galaxy S6 line-up.

The new devices were unveiled in Barcelona on the eve of the Mobile World Congress tech show.

While the Galaxy S7 retains the same sized screen as the S6, the S7 Edge’s display has grown slightly from 5.1in (13cm) to 5.5in (14cm).

The Edge version is also slightly curvier than before and its camera protrudes less far out.

In addition, the “edged” parts of the screen now provide shortcuts to email, different photo modes and third-party apps.
