Less than a month following the global roll out of the Lumia Black update, the latest version of Windows Phone is now available to be installed on the AT&T versions of the Nokia Lumia 920 and 820.
Black is actually Nokia’s enhanced version of Microsoft's General Distribution Release 3 update, the third and final update before the release of Windows Phone 8.1. This particular update includes a number of very useful features.
Introduction to Driving Mode
For those of you who cannot resist the urge to text while driving, Black adds a Driving Mode that allows you to minimize incoming calls and text messages, as seen above. Rotation lock is also now also a possibility. This ability proves particularly useful on Phablet devices, such as the Lumia 1520. Although it is unfortunately buried under a sub-menu, this useful application allows you to access the function directly from the start screen.
The glance screen functionality has also been expanded. In addition to viewing the date and time, you can now add notifications from other applications such as Facebook and Twitter, all without touching the screen. Other various changes include additional Bluetooth functionality, Imaging algorithms improvements, and the ability to close apps while in App switcher mode.
In order to see if the update is available for your 920 or 820, select phone update under the settings menu and look for “check for updates.”
