Not too much has been leaked about the Nexus 5 leading up to its launch in October, but now it seems like the flood gates have opened. Earlier this week we saw a Google employee using an unknown Nexus branded device. It looks the spitting image of the new Nexus 7, but was way too small to be the 7-inch tablet.
So the leak started rumours that this was the Nexus 5, and by the looks of it, it'd be made by ASUS. Only half of that was right. That was the Nexus 5, but it is going to be made by LG.
A filing sent to the FCC has shown off a device named the LG D820 (the LG G2 is D802 for reference), and it shows the exact same design as the leaked product we saw earlier, plus includes some specifications for us to get out teeth into.
Firstly, we have the firmware which is M8974A, which is code for a Snapdragon 800 chip, possibly the best on the market right now. Along with that, we have the build number: aosp_hammerhead-userdebugKyeLimePieFACTORYeng.sangjoon84.lee.20130618.015154.
You may think it's odd that the build number says Key Lime Pie (or Kye Lime Pie), but remember it was probably the codename Google used to develop the software before they decided on the name KitKat. This also shows that the Nexus 5 will launch with the latest version of Android, 4.4 KitKat.
The battery capacity has also been mentioned as 2300mAh, which is only a slight step up from the Nexus 4 at 2100mAh. The battery is also non-removable.
In the very unlikely chance that this isn't the Nexus 5, it could be a variant of the LG G2, but to be honest I don't see any evidence of that further than a similar D820 name and the same Snapdragon 800 processor.
UPDATE: Turns out that it was just the CDMA variant of the LG G2. Seems as though we'll have to wait a bit longer for some more information on the new Nexus phone.
UPDATE #2: Actually the model version isn't for a CDMA variant of the LG G2, it is looking increasingly likely that it's for the Nexus 5!
