According to Ausdroid and several other publications around the net, LG and Google will officially be taking the wraps off the LG Nexus 5 and Android 4.4 KitKat on 14 October. The timing makes sense, given past Nexus events held by Google in October, but nothing has yet been confirmed by the company.
Previous FCC filings noted the Nexus 5 features Qi wireless charging capabilities inside of the back cover, which will allow customers to place their device on a charging stone and forget cords. You'll find LTE bands (unlike the Nexus 4), NFC, Bluetooth 4.0, and of course, CDMA / EVDO rev A, pentaband DC-HSPA+ and quadband GSM / EDGE.
The FCC documents further revealed a 4.96-inch diagonal for display, hence the Nexus 5 name, with a length and width of 131.9 mm x 68.2 mm. A Snapdragon 800 SoC was also mentioned.
With the LG Nexus 5 allegedly getting Android 4.4 KitKat in mid-October, this means other Nexus handsets will follow in subsequent days. Ausdroid says to expect updates in the fragmentation/screen resizing area, Miracast updates, new Gallery Visualisation, new APIs regarding animations, and new notification widgets. Perhaps most notably, the blue default colour scheme found in past versions of Android will be changed to other preset palette colours.
Of course, as with all rumours, we suggest you take this one with a healthy pinch of salt. At any rate, an October release is sounding more than likely.
