The website of Carphone Warehouse briefly displayed a page offering the LG Nexus 4's specifications and pricing before the page was taken down, The Daily Telegraph reported.
The web page said the Nexus 4 -- expected to be the centerpiece of a Google event in New York Monday -- will have a 4.7-inch screen with density of 320 pixels per inch, just shy of the iPhone 5's 326, and run a quad-core 1.5 gigahertz Snapdragon S4 processor.
The screen size suggests the Nexus handset will be roughly the same size as it main competition, the Samsung Galaxy S3 and HTC One X devices.
Carphone Warehouse issued a statement saying: "Unfortunately a pre-order page for a new handset that we plan to range went live prematurely. We've now rectified this and apologize for any confusion caused."
