Microsoft, much before the release of Windows 10 for mobile phones, has brought an application for the purpose. This application will help users in knowing stuff about update. It is being called “Upgrade Advisor” and is in its beta version. This is how Microsoft describes the App: Here is a screenshot of the app’s listing on Windows store: As you can see on the screenshot, the app looks quite unfinished — especially in terms of the user interface. For those wondering, Microsoft previously stated that the Lumia 430, Lumia 435, Lumia 532, Lumia 535, Lumia 540, Lumia 635 (1 GB), Lumia 640, Lumia 640 XL, Lumia 735, Lumia 830, and Lumia 930 will be getting Windows 10 Mobile at the intial release. For now, it isn’t yet clear when the OS will start rolling out to users yet, but that should be happening Soon™ This is to be noted that the app is not available to the public yet. We will let you know as soon it becomes so. Till then we would like to hear from you on which out of two Android and Windows is better for mobile phones? Tell us in the comments.
