Google introduced two new flagship smartphones -- Nexus 6P and Nexus 5X - along with availability details about the newest version of Android, codenamed Marshmallow, Tuesday in San Francisco.

Chinese tech giant Huawei has joined the group of Google’s Nexus manufacturers with the Nexus 6P. The company is the world's third-largest smartphone-maker by units shipped, according to US research firm IDC.

According to cnet.com, in many regions, Huawei is hardly known for being a purveyor of high-quality phones. “Held aloft by Google's popular, time-tested Nexus line, Huawei now has a rare chance to impress a pantheon of established Nexus fans with its top-tier hardware,” the technology website said.
