For those using the new Nokia Lumia 930, you may want to check to see if you have an update waiting. Of course it is not Lumia Cyan, as the Lumia 930 comes with that already on board, but it is an update to it, likely fixing and improving various aspects of the hardware.
Version xxxxx.xxxx.14252.51003 of the firmware is the latest version, up from the previous 51002 build.
If, however, you are looking for a detailed changelog, you will be sorely disappointed. Then again, this most likely some minor improvements to some facets of the phone's hardware, including the display, buttons or telephony functions. Besides our review unit, another person in our forums also has an update, which wasn't available yesterday.
To check to see if you have an update, head into Settings > Phone update > Check for update to force it. Since this update is firmware, the download size should be relatively small. Not all Lumia 930s are eligible for the update, as it firmware is dependent upon the device's region (determined by previous firmware) and carrier deployment, if applicable.
