Back in September, 2014, Microsoft Mobile (formerly known as Nokia) announced Lumia Denim for their flagship devices like the Nokia Lumia 930 and the Nokia Lumia 1520.
The update, was pre-installed in Microsoft Mobile’s brand new devices, the Nokia Lumia 830 as well as the Nokia Lumia 730/735 (based on configuration)
As the rumors of Windows Phone 8.1 Update 2 for Developer Preview users is in the works, we start getting the name of what might be the next Lumia firmware!
While scouring the internet, I ran upto this image which also indicates the name of the Firmware, which is Lumia Emerald.
Nokia started with their Firmware naming with A (Amber), then B (Black), C (Cyan) and now D (Denim). According to this order, E should be the next, hence leading to Lumia Emerald (goes with Nokia new “green” color too)
You can notice some changes to the extras+info page like the SpamFilter version bumped to v2.0.0.0. Another thing that you can notice is that the Lumia “Emerald” firmware is supposedly running on a Nokia Lumia 830 (if you own one, you would know)
Anyways, while Windows Phone 8.1 update 2 aka GDR2 will roll out to dev preview devices in October, Lumia Denim should roll out in early November. Now, to the question of when one can hope to get Lumia Emerald, it may well be January-February 2015, when Windows 10 previewfor Windows Phone (to dev preview devices) and Lumia Emerald (to regular Lumia devices) may both roll out.
Just keep one thing in mind, Lumia Emerald may or may not be the final name of the GDR2 Lumia Firmware. As usually Lumia firmwares have codenames to show. You may remember, us exclusively reporting about Lumia Bittersweet Shimmer, which later arrived as Lumia Black.
