And this tumescence is changing what people do with their handsets.
Kantar Worldpanel ComTech has tracked the trend for bigger screens and says 29 per cent of phones sold in Q2 were bigger than 4.5 inches. It reckons it's affecting video consumption in particular – with two thirds of users watching when they have a phone over five inches in size.
Dominic Sunnebo, global consumer insight director at Kantar Worldpanel ComTech, said: “It is interesting to look at the impact a larger screen size has…particularly as the line between tablets and smartphones becomes more blurred.
"Consumers who own a smartphone with a larger screen tend to be much more engaged with their device across a whole array of functions. For example, only 19 per cent of consumers with a screen smaller than three inches download and watch videos, compared to 65 per cent when the screen is five inches or more."
Elsewhere the stats show Android continues increased its share of the European market by 20.2 per cent in the past year. Surprisingly, Windows has managed to maintain its per cent share despite a raft of new Windows 8 products being announced. However, this has been achieved through heavy discounting.
