We have been hearing about Google's next Flagship smartphone "Nexus 5" in rumors since past couple of days. The device is about to be launched at upcoming Google I/O which is to be held in October. Also we know that the device will be coming with the Google's next Android version "Android 4.4 KitKat". Here is the spotted image of Nexus 5 at FCC before its launch:

Earlier there were rumors that the new Nexus 5 will be made by Motorola, but now it appears to be LG. Probably it would be "LG D820" as Nexus 5 powered with MSM8974 SoC Snapdragon 800 processor with 5-Inch Display. I will try to get some more info about the device very soon.
