Vivo announced today an upgrade to its existing flagship series, NEX, at a launch event in China.

Building on the premium line-up, NEX Dual Display Edition offers a dual-screen design and a triple camera setup.

The 6.39-inch Ultra FullView Display (1080p) at the front has an improved screen-to-body ratio of 91.63%, and offers a notch-free viewing experience to users.

With an additional 5.49-inch Super AMOLED display (1080p) gracing the phone's back, NEX Dual Display Edition allowes greater flexibility in using the rear cameras. Snapping selfies is now easier, as users can simply use the main cameras along with the rear screen to get the perfect angles for selfies.

In addition, the Lunar Ring featured on the rear display creates a glowing band of colors which can signify notifications and even pulse with music.

The NEX Dual Display Edition's triple camera setup consists of a 12MP Dual-Pixel main camera (featuring a Sony IMX363 sensor and 4-axis OIS), a specialized Night Video Camera and a Time of Flight (TOF) 3D Camera.

The Night Video Camera helps users film stable footage in motion and low-light environments, while the TOF 3D Camera empowers users to see the world with an added dimension. Its 3D sensing capabilities not only enables point-to-point distance measuring, but also supports 3D Modeling of the user's face for enhanced facial recognition, protection and personalized beautification.

Vivo has also created more camera modes for the NEX Dual Display Edition, such as Mirror Mode and Pose Director. Mirror Mode allows users to see themselves in the rear display while being photographed or filmed, while Pose Director can show a posed image or video in the rear display as reference for imitation. The se fatures are coupled with other camera modes such as AI Scene Recognition, AI Filters and AI Portrait Framing, along with the diffusion lighting from the Selfie Softlight as part of the Lunar Ring.

The NEX Dual Display Edition adopts the Qualcomm Snapdragon 845 octa-core processor and comes with 10GB RAM and 128GB ROM. It is also featuring In-Display Fingerprint Scanning technology, and a TOF 3D Camera with 3D sensing technology for facial recognition protection.

The rest of this Android 9.0 phone is very much what you would expect from a standard flagship, but with 10GB RAM. You get the usual Qualcomm Snapdragon 845 chipset, 128GB internal storage, a 3,500mAh battery, an in-display fingerprint reader -- now at its fifth generation which unlocks in 0.29 seconds - and a TOF 3D Camera with 3D sensing technology for facial recognition protection. Hi-fi enthusiasts may also appreciate the integrated AK4377A 32-bit audio DAC chip from Asahi Kasei Microdevices.

On the weak side, teh snartphone lacks support for NFC.

The Vivo's NEX Dual Display Edition is also a dual nano SIM device, but it doesn't support most of the US LTE bands.

You can either grab either a "polar blue" or "nebula purple" unit in China from December 29th for 4,998 yuan (about $725), or wait until the international version (blue only) hits the markets in Hong Kong, Taiwan and Singapore in the near future.
