Microsoft has announced on its website that it will start rolling out Windows Phone 8.1 update from June 24th for compatible devices. The recently announced Lumia 930, Lumia 630, Lumia 630 Dual SIM and Lumia 635 will come with Windows Phone 8.1 pre-installed. Microsoft is supposed to announce some of these devices on May 12th, that is, today.
Microsoft will make updates available for the Operating System, including security updates, for a minimum of 36 months after the lifecycle start date. These updates will be incremental, with each update built on the update that preceded it. Customers need to install each update in order to remain supported. The distribution of these incremental updates may be controlled by the mobile operator or the phone manufacturer from which you purchased your phone, and installation will require that your phone have any prior updates. Update availability will also vary by country, region, and hardware capabilities.
All the devices running Windows Phone 8 will be eligible for the Windows Phone 8.1 update. Microsoft is promising 36 months (3 years) of software updates and support for the Windows Phone 8.1 operating system. Windows Phone 8.1 comes with dozens of new software features including a native file manager, Cortana voice assistant, action centre, installation of apps on SD cards, dual SIM card support, new camera interface, IE 11, WordFlow Keyboard, etc. Although it may take time for the update to reach all the compatible devices, so be patient.
