Shenzhen-based smartphone maker Gionee unveiled a six-inch screen handset in Beijing on Monday, reinforcing its edge in security functions.

Dubbed the M6S Plus, the handset is equipped with built-in security encryption chips and EAL4 + security certification. The fingerprint sensor, which is able to record the user's heart rate, guarantees security of users' privacy and personal data.

Another feature of the new product is the large battery with a capacity of 6020mAh, with support from Qualcomm's Quick Charge 3.0 standard.

Powered by Qualcomm's Snapdragon 653 octa-core processor, Gionee M6S Plus has 6GB RAM and dual shooters, a 12-megapixel rear camera and an eight-megapixel camera in the front.

The Gionee M6S Plus 64GB model is priced at 3,499 yuan and the 256 GB model at 4,299 yuan.

The new product will be available on May 2.

A report from US telecom research company Strategy Analytics said that Gionee is among the top smartphone brands in China and is ranked in the top 10 worldwide, with 30 million handsets sold last year.

Gionee saw solid growth in 2016 due to its expansion in the offline channel in the lower tier cities, according a report from market research company IDC.

"To differentiate itself from OPPO and vivo, who predominantly target a younger audience, Gionee has been targeting professionals and executives, and hence found a niche market for itself to stand out against its two competitors," the IDC report said.
