I was under the impression that the Cyan update was firmware and OS together. Now as per Daniel "Lumia Cyan is the third firmware update from Nokia's mobile division, now owned by Microsoft. Lumia Cyan is distributed in parallel with the Windows Phone 8.1 OS update, and provides the necessary drivers and APIs for specific Lumia devices. As such, it enables unique Lumia features like the PureView camera, Living Images and an updated Creative Studio editing app, in addition to optimizing the battery, performance, Bluetooth 4.0 LE, a revised Camera app and general telephony functions."
now the "tiny updates that I mentioned like the camera, studio, display and network+ they pretty much would cover what is mentioned above. So what is the buzz about?
