The Mobile World Congress grows bigger every year. Over 93,000 visitors from 200 countries attended the 2015 MWC at the Fira Gran Via and Fira Montjuïc venues in Barcelona; more than 2,000 exhibiting companies showcased their latest products and services across 100,000 net square meters; more than 2,800 international media and industry analysts were present to report on everything that took place at the Congress.

The display measures 5.1 inches with a resolution of 1440 x 2560 pixels (~577ppi pixel density), protected by the latest Corning release, the Gorilla Glass 4.
