Read on some tech website that Nexus 6X would have sounded like iPhone 6S, or even something more funnier. So name 6P. Or else Huawei has flagship with names P, so 6P relates with its cousins from Huawei.
Nexus 6P is the first all-metal-body Nexus phone. Built in collaboration with Huawei, this 5.7” phone is crafted from aeronautical-grade aluminum, with a USB Type-C port for fast charging, a powerful 64-bit processor, and a 12.3 MP camera sensor with massive 1.55µm pixels (hello, better photos!). The Nexus 6P starts at $499.
