What to expect from Mobile World Congress 2016

New-generation flagship smartphones from Samsung, LG, Huawei and Sony are expected at the event, as well as appearances from prestigious special guests.

Stars of the show: Samsung Galaxy S7, LG G5

New versions of some of the most innovative and high-performance smartphones on the market are being lined up for the Barcelona trade show, with replacements for the Samsung Galaxy S6, the LG G4 and the Huawei P8 expected at MWC 2016.

Samsung is likely to grab the most column inches with the Galaxy S7 and Galaxy S7 Edge, which brings curved edges to the handset's display. These new models should be up for release from March, while a "Premium" version with a 4K screen and a 14-core processor could be heading for the Asian market.

As well as unveiling its flagship G5, South Korean manufacturer LG is expected to launch two models in a specialist new mobile phone range. The LG X Cam handset gets twin 13- and 5-Megapixel rear-facing cameras, while the X Screen comes with a dual-display design.

Although new handsets are likely from Huawei, in the form of the P9, and Sony, other innovative models could steal some of the limelight. The Cat S60, for example, is a waterproof, high-resistance handset that's billed as the world's first smartphone with a built-in thermal imaging camera.

Alongside smartphones, plenty of connected devices will be on show at the Barcelona event, with freshly unveiled models plus products presented back in January 2016 at CES in Las Vegas.

Mark Zuckerberg takes center stage

Each year, the Mobile World Congress invites big names from the telecoms industry to share their vision of the sector in a series of conferences and debates.

After outlining Facebook's mobile strategy at MWC 2015, Mark Zuckerberg will once again be the undisputed star of the Barcelona trade show.
