The big global trend this month is the continued growth in popularity of the 640 and 640XL. The 520 continues to be the most popular device in use worldwide but that popularity continues to decline. We look in detail at the US, Mexico, Brazil, Germany and Italy. Plus we have our first look at Turkey. This report also marks our third anniversary for detailed monthly statistics on Windows Phone usage. Back in November 2012 the first Windows Phone 8.0 devices had just gone on sale (5% market share) and the most popular device in use worldwide was the Lumia 710 with a 24% share. Things have changed a lot since then.
