While Google didn't unveil new Nexus devices at its I/O conference in June, all is not lost for fans of the company's own smartphone. Head of Android engineering David Burke told ReadWrite that the company is building a Nexus device as it writes the source code for its latest operating system. The purported Nexus 6 could follow in the footsteps of the iPhone 5s and Galaxy S5 by including a fingerprint sensor. It is also expected to sport a 5.5-inch, 2560 x 1440 display and a quad-core Qualcomm Snapdragon CPU or an octa-core LG Odin chip. Google's Android L is likely to power the device, which has a new design.
