Screenshot shows Nexus 5 running KitKat27
Besides the screenshot, we also have the log files that confirm LG as the manufacturer and also show that the resolution on the screen will be 1080 x 1920 which is FHD, of course. The log files also show that the Nexus 5 will support wireless charging. The version of Key Lime Pie running on the device is KRS74H, and dates back to September 13th. Additionally, the log files show that this phone is called Hammerhead which is the code name for the LG D820, more affectionately known as the Nexus 5. Linux Kernel version 3.4.0 is apparently what the Nexus 5 is running on.
