Slowly but surely, Windows Phone is gaining some momentum, but it still has a long way to go to catch up to Apple's iOS and Google's Android. But Microsoft is hoping that the latest update to its mobile operating system will help it attract more customers.
Rolling out to existing Windows Phone 8 devices in the coming months, and shipping on new devices like the Nokia Lumia 635 this summer, Windows Phone 8.1 adds a number of new features, including a voice-guided assistant, a notifications center, and tools for better managing Wi-Fi networks. None of this is groundbreaking. The iPhone and Android handsets have had similar functionality for years.
