Developed under Google's direction, the new high-end Android handset is expected to have features like an all-metal body, Gorilla Glass screen from Corning and fast-charging technology.
Better known for its lower-end phones in the worldwide market, Huawei remains less popular in the United States. It stands to see major market share gains thanks to its Google partnership, however.
In the second quarter of this year, the Chinese manufacturer held close to 9 percent of the worldwide smartphone market, ranking it third in market share, according to research firm IDC. Samsung leads the pack with 21 percent of smartphone market share, and Apple has 14 percent.
