Google Nexus 4 'leaked' by Carphone Warehouse The retailer's website briefly displayed a listing offering the LG Nexus 4 on contract from £31 per month on O2 or Vodafone from 30 October. The device is expected to be the centrepiece of a Google event in New York on Monday, 29 October, when the web giant is also expected to update its Nexus 7 Android tablet. Carphone Warehouse's page, which has now been removed, said the Nexus 4 will have a 4.7-inch screen with density of 320 pixels per inch, just shy of the iPhone 5"s 326. The handset was listed as measuring 68.7 by 133.9 by 9.1 millimetres, apparently thicker than its Apple rival's 7.6 millimetres. The Nexus 4 is expected to run an updated version of the current version of Android 4.1, Jelly Bean, rather than the next full-blown release, 4.2, codenamed Key Lime Pie. The incremental update appeared to be confirmed by Carphone Warehouse's page, which said it will run Jelly Bean 4.1.2 on a quad-core 1.5GHz Snapdragon S4 processor. Google has previously used its Nexus own brand as a proving ground for new Android feature before they are included in handsets from other manufacturers, such as Samsung's bestselling Galaxy S range. Carphone Warehouse's page said the new Nexus will have a 360-degree panorama feature, via its eight megapixel camera. The new version of Android is also expected to feature a new Gmail app that will add minor additions such as swipe to delete and pinch to zoom. The "leaked" listing offers a version of the Nexus 4 with only 8GB of storage, though earlier leaks have suggested there will be a version with at least 16GB too. With the Nexus 7 tablet, Google offered only up to 16GB, in contrast to the up to 64G availablt to iPad buyers, as part of efforts to encourage customers to use its online storage services.
