Latest model launched, and another promised by end of year as firm aims to boost sales

Lenovo Group Ltd unveiled its latest smartphone on Tuesday, the ZUK Z2, which it hopes will rejuvenate sluggish sales and return it to the top tier of phone makers within two years.

Priced at 1,799 yuan ($273) and equipped with Qualcomm Inc's Snapdragon 820 processor, the newest device features a smaller 5-inch screen than the previous ZUK Z2 Pro model, which was only launched in April.
