Yesterday, ZTE launched its first product, the Nubian Z5, which entered the high-end market. The high-priced version has a price close to 8,000 yuan, which is extremely rare in domestic brands.
In October of this year, ZTE announced that it has formed a mobile phone team that focuses on the high-end market. Its brand name is “nubiaâ€. Two months later, the first product finally appeared. This product focuses on the most mainstream high-end configuration, 5.0-inch high-definition screen, 13-megapixel camera, quad-core 1.5GHz processor and so on. In terms of price, it is also close to the high-end products of international brands. One of the titanium versions costs 7890 yuan.
