Windows Phone 8.1

Windows Phone 8.1: Top eight new features

Microsoft launched its highly-anticipated Windows Phone 8.1 update at its keynote address at the Build 2014 conference on Wednesday. The event also saw the unveiling of the Windows 8.1 Update operating system version, alongside three new devices, Nokia Lumia 930, Lumia 630 and Lumia 635, which will be the platform lead devices for Windows Phone 8.1 OS version.
Microsoft's Joe Belfiore, VP Windows Phone program management and design, introduced a bevy of enhanced features in the Windows Phone 8.1 that the Redmond giant hopes will bring more personal and smarter experience for consumers.

Microsoft has announced that Windows Phone 8.1 will start rolling out to Windows Phone 8 users in coming months. The Redmond giant also confirmed that the entire Nokia Lumia range will get OTA (over-the-air) update called Lumia Cyan, which will include Windows Phone 8.1 features and the new Lumia features into one update.

I've broken down the eight biggest new features in the Windows Phone 8.1 including the ones that made it into the highlights - Cortana, Action Centre, Word Flow and more personalised Start Screen.

1. Greater Start Screen personalisation

Microsoft in an attempt to offer more customisable options to Windows Phone users, has added 'Start background' feature that allows users to add an image to the tiles on the Start screen of the device.

The feature will add an image of the user's choice to multiple tiles on the Start screen. Earlier, the Live Tiles on the Start screen on Windows Phone 8 were limited to solid colours.

In 2013, Microsoft added the third Live Tile column on the Start screen of the Nokia Lumia 1520, and then left it to manufacturer adoption. However, with the Windows Phone 8.1, the company has now added an extra column of Live Tiles on all screen sizes, with users able to choose whether to turn this feature on.

2. Cortana: Finally arrives to take on Apple's Siri and Google's Google Now

One of the highlight features of Windows Phone 8.1 is Cortana, which is Microsoft's voice-based virtual assistant. The Redmond giant's Cortana is based on a popular AI character in Microsoft's blockbuster video game franchise, Halo.

Cortana is powered by Bing and is similar to Apple's Siri or Google Now, completely replacing the search feature in WP8.1. Microsoft's Joe Belfiore claimed that the new digital assistant from Microsoft will get better with time as a user spends more time with it by asking questions to Cortana, filling up details in its Notebook section.

Cortana can be launched by pressing the Live Tile placed on the Start screen or by pressing the Search button on the Windows Phone device. Belfiore said that Cortana can interact verbally or by typing, and stressed its ability to understand natural language voice commands. It can also interact with third party apps, though developers will have to build Cortana-compatibility into their apps.

Microsoft has announced that Cortana will be available first in the US as a 'beta' and later will released in the UK and China in the second half of 2014, while in other countries Cortana might reach by 2015.
