Every year we like to take a look at the state of mobile usage around the world, what platforms dominate in each country and how this has changed over time. The last 12 months have seen some interesting changes in the mobile landscape with Android being the biggest winner and Nokia the biggest loser.

In the UK Blackberry continues to hold on for dear life as it slips from 2nd into 3rd position, dropping 11 percentage points over the last 12 months. Interestingly the UK is one of the last few markets where Blackberry holds any significant market share (Canada is another). Android is the big winner in the UK increasing its share by 10% to bump it up to second place behind market leader Apple.

In the USA Apple has strengthened its position increasing market share slightly in the past year (8% increase), while Android has remained level. Blackberry continued its decline in the US and now holds less than 2% market share.

Countries such as Germany, Spain and France have all increased their Android market share, however some of the biggest increases have happened in countries such as Brazil and China where Android's market share has increased by 26% and 50% respectively.

Russia has seen a sharp drop in Nokia’s market share with the Finnish handset maker losing 19 points over the past 12 months and Android picking up the majority of that loss (up 18 points).
