Samsung Electronics swept five awards at the Mobile World Congress in Barcelona on Tuesday. The Groupe Spéciale Mobile (GSMA), the organizer of the world's biggest mobile exhibition, selects winners of the annual awards from among global phone and communication devices manufacturers.

Samsung won Best Smartphone for its Galaxy S3, and Best Mobile Enabled Consumer Electronics Device for its Galaxy camera. It also grabbed awards in the categories of Device Manufacturer of the Year, Best Mobile Infrastructure, and Outstanding Overall Mobile Technology -- the CTO's Choice.

Meanwhile, LG Electronics' Optimus G was named the best product of the MWC by Ubergizmodo and Tom's Hardware.

The most notable products at this year's MWC were smartphones with high-resolution screens larger than 5 inches.

LG, Huawei and Nokia showcased cheaper versions of LTE smartphones to expand their markets. LTE smartphones are estimated to post a three-fold on-year growth in sales to 275 million units this year.

New mobile operating systems such as Firefox and Tizen were also released at the exhibition in a bid to take market share from Google's Android and Apple's iOS.
