Microsoft executives say Firefox OS intensifies competition for Android BlackBerry imitation wp

"The advent of Firefox means that the smartphone industry will be full of competition and uncertainty," said Greg Sullivan, senior product manager at     Microsoft's Windows Phone Department, Gregg Shaliven. Competition in the mobile arena is far from over. "Sullivan believes that Firefox will support low-end smartphones, but it remains to be seen what the devices are." At the same time, Windows phone can provide a high quality user experience across a wide range of low-end and high-end devices.       Windows Phone based Nokia Lumia 920 offers "top-tier" hardware, which this week also launched Lumia 520 and Lumia 720. Stephen Elop, Nokia's chief executive, Elop that the goal of the new handset is "to push innovation to more people".      Sullivan said Microsoft did not set up a booth at the MWC conference, but Microsoft used a shuttle bus to get the hotel to show how Windows Phone 8 allows users to run programs across platforms, including the PC platform and the Xbox platform.      Sullivan said: "Our philosophy is to allow users to do things in a completely different way." "     Microsoft officially admits that Microsoft needs to do a better job of demonstrating cross-platform capabilities for Office 360, Excel and other Office applications." As early as Windows Phone 7 was released, Microsoft tried to deliver the message to the outside world.      But users still complain that in order to run on three different platforms, such as Xbox, PC and Smartphone, they must purchase three different versions of the program.      While demonstrating "the Shogun's skull" (skulls of the Shogun), Sullivan said he had to buy 3 game versions on Xbox, Windows phone and PC platforms, with a total cost of $25.      Sullivan said Microsoft might end up allowing users to buy different versions of apps in an App store. Currently, although Windows Phone and Windows 8 use the same kernel, they are not equivalent, and developers need to adjust the program based on factors such as screen size, resolution, and so on.      Sullivan says Windows phone has won honors and some basic features have been recognized, including actually the tile interface. The new BlackBerry 10 smartphone draws on the idea of real-time tile design. Some Android phones even useA similar interface design.      Sullivan said: "The emulation of other platforms is the affirmation of Windows Phone." ”
