Employees from LG and Google have both uploaded photos to Google+ using the unreleased device, and the EXIF information for the shots both call the camera that has been used 'Nexus 4'.
Both of the photos were taken on Saturday, and uploaded to the social network over the weekend. Jason Parks, a Google employee, still has them on his profile, although due to the sensitive nature of the shots, we've chosen not to publish them. His South Korean counterpart, Bae Sang-Hoon, has since removed the posts.
Following a leak from Carphone Warehouse's inventory last week, also naming the device Nexus 4, this all but confirms what the device will be called when it is eventually released.
