Google Nexus is a line of mobile devices using the Android operating system produced by Google in conjunction with an original equipment manufacturer (OEM) partner. Devices in the Nexus series[1] do not have manufacturer or wireless carrier modifications to Android (such as custom graphical user interfaces), and have an unlockable bootloader[2] to allow further development and end-user modification.[3] Nexus devices are the first Android devices to receive updates to the operating system.[4][5][6] The Galaxy Nexus is one of the few smartphones recommended by the Android Open Source Project for Android software development.[7] As of November 2012[update], the latest devices in the series are the Nexus 4 phone by Google and LG, and the Nexus 7 and Nexus 10 tablet computers by Google with Asus and Samsung respectively.
