The new update, previously thought to be called the Windows Phone GDR3 update, brings some of the most awaited features to the Windows Phone platform that includes support for bigger display (5-inch and 6-inch displays) that will now house six Live Tiles instead of four, as found in previous version; support for higher resolution (full-HD or 1080p) displays, which paves the way for yet to be released Windows Phone devices (like the rumoured Nokia Lumia 1520); support for more powerful processors, like the Qualcomm Snapdragon 800 quad-core processor, and improvements in Internet sharing, which now adds a pairing feature for a Windows Phone 8 device and Windows 8.1 PC or tablet over Bluetooth for sharing cellular data via Wi-Fi hotspot.
The third Windows Phone 8 update also adds more 'Mobile Accessibility' features for Windows Phone 8 devices, including a suite of apps like screen reader, meant for the convenience of blind and visually impaired users, allowing them to manage calls, contacts, texts, emails and also hear notifications like calendar, alarm, events and low-battery warnings.
The latest update for the Windows Phone 8 platform brings a new Driving Mode feature that will limit notifications for calls, texts and emails on the phone's lock screen while driving. This feature can also be set for automatic replies to contacts for calls and texts while driving.
There are some minor changes added to the third WP8 update that include custom ringtones for messages, emails, voicemails, reminders and contacts; new rotation lock option to keep the device's screen in place while using it; new storage management feature that will allow users to free up space on the phone and manage temporary files; app switcher to close background apps; some enhancements in connection quality for Bluetooth-attached accessories, and finally, users will be prompted to set-up Wi-Fi during phone's start up process.
Darren Laybourn, Corporate Vice President, Windows Phone further adds in a blog post, "When we sat down to plan our latest official update to Windows Phone 8, we had three main engineering goals in mind - enable incredible new Windows Phone devices, enhance the platform with new capabilities for current users and partners and improve overall quality."
