Chinese smartphone manufacturer Nubia Technology Co Ltd is bringing its innovative dual-screen technology to the flagship line of smartphones with the launch of Nubia Z20.

The new Z20 features two curved displays, a primary 6.42-inch AMOLED screen on the front, and a full-featured 5.1-inch touch display on the back of the device. Users can take photos or video chat using the high-quality rear camera with the ease of a front-facing camera.

The phone has a triple rear-camera setup at the back with a 48-megapixels (MP) Sony IMX586 sensor, 16MP ultra-wide angle camera, and an 8MP telephoto camera with 3x optical zoom that can create shots with 30x digital zoom.

The Nubia's dual-screen technology isn't just about photography as users can choose to have each screen operate independently, allowing for quick-switching between games, messages, apps, and more. The rear screen also doubles as an always-on display, and its rhythmic lighting effects can be customized for calls, music, games and more.

Priced from 3,499 yuan ($496), the Nubia Z20 is already available for pre-order in China and will ship August 16 onwards.

In early April, the Shenzhen-based company unveiled its first wearable watch-like smartphone Alpha, which features a four-inch flexible screen manufactured by Visionox Co Ltd, an OLED supplier. The Alpha has all the features and functionality of a phone but wraps around the wrist like a smartwatch.
