Lumia 630 - one of the first smartphones to be installed Windows Phone 8.1
Neowin cited AdDuplex 's report as saying that Windows Phone 8.1 has a rapid growth thanks to Microsoft beginning to market the cheap Lumia 630 and Lumia 635 smartphones with Windows Phone 8.1 pre-installed.
In addition, a large number of users of the programmer group have upgraded their device from Windows Phone 8 to version 8.1 to experience the new features that this platform brings.
According to AdDuplex report, the market share of Windows Phone 8 users is still the highest with about 77% market share; followed by Windows 7.x with 17.8% market share.
Reportedly, Windows Phone 8.1 is an improved version of the lockscreen interface, which is more fun, allowing users to customize Live Tile into 4 or 6 small boxes. In addition, users can create wallpapers (can take personal photos) inserted into the Windows Phone interface, something that Windows Phone 8 does not support.
In particular, Windows Phone 8.1 is integrated by Microsoft with the intelligent virtual assistant ( like Siri's Apple ) called Cortana.
It is expected that the updated version for Windows Phone 8.1 ( for users who are using Windows Phone 8 version ) will be released in mid-June.
