In the next few months, Nokia is expected to release a forthcoming firmware update for their Lumia line. That should be no secret as we’re also expecting an OS update called Windows Phone 8.1. Firmware helps make your phone’s hardware better, and it’s very specific to your device. The OS though is general. That’s why the Developer Preview Program only gives the OS update, but requires additional firmware updates later on to complete the experience.

OS updates and firmware are like Sith, there are always two.

Now, a new video posted by Nokia Russia highlights the current features in Lumia Black. That’s the firmware that coincides with Update 3. That in and of itself is not news, but at the very end of the video, the voice over makes brief mention of the next Lumia update, and even call is by name: Nokia Blue.

‘Blue’ is the codename for Windows Phone 8.1 (and other Microsoft services), so Nokia calling their new firmware ‘Nokia Blue’ makes a lot of sense. (It’s also kind of funny, since we have Black and Blue for those two firmwares).

Assuming the information is correct, the firmware/OS pattern will look like this:

There's almost a semblance of a pattern there.

So what’s in Nokia Blue? That’s a good question, and we really don’t know yet.

In the past, firmware like Nokia Blue has “unlocked” some features like advances to the Glance screen, better Bluetooth support, improved camera algorithms, Motion Monitor and more. Presumably, there could be some advanced features in the 8.1 OS update that are taken advantage of by newer chipsets found in the Lumia Icon and Lumia 1520 e.g. always-on voice recognition. Firmware would be needed there to enable those and other features.

We’re reaching out to various sources to confirm the firmware name and any other details. But due to the obviousness of the name and a Nokia video calling it 'Blue, we're leaning heavily on this. Then again, before Lumia Black was Lumia Black it was called Bittersweet Shimmer. Stay tuned.
