The Nexus 6P is a device co-developed by Google (software) and Huawei (hardware) and released in 2015. The all-aluminum casing was a departure from previous plastic or metal and glass Nexus devices, which helped the device come in thinner and lighter than previous phones. Packing 518 pixels per inch into its 5.7” display, the phone features a powerful 8 megapixel front-facing camera and a quick-focusing 12.3 megapixel rear camera.
