Is Google planning to refresh the Nexus 5 too soon as an LG smartphone bearing the model number LG-D830 surfaced out of the blue, or at least scant details of the supposed 2014 Android flagship?

From Phone Arena, the LG-D830 was detected courtesy of a benchmark test result with the gadget registering top numbers in browser performance. The same report hinted too of a 1080p display resolution or mirroring the same screen prowess that was seen in the Nexus 5.

What makes it a Nexus 5 second build candidate? CNET noted in a report that LG-D830 is sequentially related to LF-D820, which of course is the LG-assembled Nexus 5. However, the tech site allowed that it could be an entirely different animal, likely of the high-end breed.

Cross referencing the D830 to the LG G2, which carries the model number LG-D802, keen LG watchers could arrived to the conclusion that it is the second coming of the mildly successful Optimus G Pro.

For the 2014 edition, the chatters suggest that LG will dub the D830 as the G Pro 2. Among its so-called power specs and features is an awesome camera that will boast of a 16MP rear camera sensor.

The device is also rumoured to become the first Android that will show off a 4K display, boosting the screen feature mentioned above.

One notable feature of the D830, Phone Arena said, is that it will allegedly run on Android OS KitKat, which somehow eliminates it as a Nexus 5 replacement. If Google, indeed, is planning to issue a new Nexus mobile phone, it should be safe to assume that Android 4.5 or 5.0 will be on board.

The talks point to Key Lime Pie as the next Android star for the upcoming Nexus smartphone.

However, if the Google plan is only to rollout an enhanced Nexus 5, that is to better compete with existing and upcoming iOS/Android rivals, then the D830 fits the bill of an early Nexus refresh. The likelihood is, it will be powered by KitKat 4.4.2 and the launch date could be within the next few months.

Another possibility is that the D830, whether it is the Optimus G Pro 2 or the enhanced Nexus 5, will be previewed come the 2014 Mobile World Congress that Barcelona will host in mid-February.

Now that begs another question. In outing the improved Nexus 5 (LG-D830), will Google also give the signal for the long-delayed Nexus 10 2 release date?
