AT&T and Nokia have started rolling out the Lumia Black update for Lumia 820 and Lumia 920.
Included in the deal are many new features such as new colors on the glance screen for night mode, new notifications in glance screen, Bluetooth 4.0 LE connectivity and so on. Plus, you also get to benefit from a number of tweaks and changes included in the Windows Phone 8 GDR3.
If your Lumia still hasn’t prompted you to update, hop over to Settings -> Phone update and check whether new firmware is awaiting.
Yup, you should tap the “Update” button as soon as you can. Just make sure your Lumia has enough juice to get you to the end of the process. Moreover, you’re best off connecting to a local (and fast) Wi-Fi network to make this a seamless experience. Good luck. 😉
