Nubia Z70 Ultra: A True Full-Screen Flagship Leading the Future of Smartphone Interaction

Nearly eight years since the inception of the full-screen concept, smartphone manufacturers have explored various screen solutions in pursuit of the ultimate visual experience. However, the ideal of a "true full-screen" has remained elusive. Throughout this lengthy exploration, Nubia has persistently pursued the true full-screen vision, relentlessly overcoming technological hurdles. The result is a landmark achievement embodied in the Nubia Z70 Ultra. This flagship phone utilizes seventh-generation under-display camera technology and, for the first time, features a 1.5K ultra-high-definition screen, achieving a truly 100% full-screen visual experience and delivering an unprecedented visual feast for users.

I. Exterior Design: The Ultimate Interpretation of a True Full-Screen, a Perfectionist's Dream

The Nubia Z70 Ultra boldly breaks free from traditional phone design constraints, abandoning the so-called "iPhone-esque aesthetic" and standing out with its unique design style. The back of the phone features a center-of-gravity design, continuing Nubia's signature "Cosmic Window" design philosophy. Three camera modules are seamlessly integrated into the body, extending to the edges of the phone with a "borderless" design, creating a visually infinite effect.

The customized 35mm main camera lens boasts a classic, luminous red ring, highlighting its professional quality. This unique visual language has become a signature feature of Nubia. It's noteworthy that this main camera incorporates a ten-level adjustable aperture diaphragm Nubia's first flagship phone with this feature providing users with enhanced photographic control. To the right of the main camera is a color temperature and flicker sensor; below is a periscope telephoto lens supporting 50x digital zoom and OIS optical image stabilization, along with a noise-canceling microphone. Next to the telephoto lens is an ultra-wide-angle lens, followed by a dual-LED single-color temperature ring flash, with a laser autofocus sensor integrated in the center.

Leveraging seventh-generation self-developed under-display camera technology, the Nubia Z70 Ultra boasts the world's first 1.5K ultra-high-resolution true full-screen, achieving a genuine 100% full-screen visual experience. This 6.85-inch AMOLED flexible straight screen offers a 26881216 high resolution, a pixel density of 430PPI, and utilizes diamond pixel arrangement, independent pixel driving, and a UDC Ultra independent display chip. Combined with nano-level high-transparency materials, the front camera delivers exceptionally clear images even in its invisible state. Equipped with AI Lingtou Algorithm 7.0, it significantly improves image performance in complex lighting conditions. Furthermore, the screen supports 100% DCI-P3 wide color gamut, a 144Hz refresh rate, and up to 2592Hz PWM dimming, offering excellent eye protection and receiving SGS low blue light certification. The screen is protected by second-generation Dragon Rhinoceros glass, further enhancing its drop and scratch resistance.

Thanks to FIAA extreme compression wiring technology and super COP packaging technology, the Nubia Z70 Ultra achieves an extremely narrow 1.25mm screen bezel, resulting in a screen-to-body ratio of 95.3%. Even more impressively, the phone adopts a four-sided symmetrical design, perfectly satisfying the perfectionist's pursuit of symmetry.

The side power button retains Nubia's classic red design, and a new camera quick-launch button has been added. Regardless of the phone's status, a long press quickly activates the camera, a short press focuses, and a single press takes a picture, making photography easier and more convenient. The left side integrates an ergonomic customizable sliding button, which, with a simple flick, quickly opens the camera and can be customized for functions such as mute, recording, flashlight, game space, and translation. The top houses an infrared remote control sensor and a noise-canceling microphone, while the bottom features independent speaker openings, a Type-C port, a microphone, and a SIM card slot. The Nubia Z70 Ultra employs symmetrical dual speakers in a receiver-style design, delivering an immersive stereo experience. An 80W fast charger is included in the package.

II. Imaging System: A Classic Focal Length Combination, Showcasing Exceptional Imaging Capabilities

The Nubia Z70 Ultra features a triple rear camera system using a classic combination of three focal lengths: a 50-megapixel customized 35mm Sony IMX906 main camera, a 64-megapixel 85mm telephoto lens, and a 50-megapixel 13mm ultra-wide-angle lens.

The customized 35mm main camera, considered the golden focal length, offers advantages such as a greater shooting distance, clean and simple images, and the ability to perfectly blend subjects and environment, creating excellent subject highlighting effects. When the main camera is cropped to a 50mm focal length, it closely matches human eye perspective, accurately capturing facial expressions and emotions, resulting in more realistic and vivid photos. At the same time, it provides a pleasing background blur effect, making the subject stand out even more.

The 85mm telephoto portrait lens maintains a greater shooting distance, minimizing disruption to the subject. The reduced field of view also helps avoid cluttered surroundings, focusing on the center of the image for more natural portraits. Thanks to the 64-megapixel lossless image output, the resulting portraits are bright and clear, with significantly improved resolution details remain visible even when zoomed in.

The 13mm ultra-wide-angle lens offers ample light intake, capturing rich light and shadow details even in backlit scenes, easily meeting the needs of various large-scale shooting scenarios. Additionally, distortion correction is enabled by default, ensuring the integrity of the image edges and avoiding the cropping or blurring issues often associated with traditional wide-angle lenses, resulting in clearer and more natural images.

III. AI Experience: Nebula AIOS, Unveiling Future Interaction Modes

The Nubia Z70 Ultra is equipped with the Nebula AIOS system, providing a new interaction mode Future Mode. In Future Mode, the UI interface is extremely minimalist, retaining only the clock and voice assistant. Users can interact with the phone purely through voice commands, efficiently completing various tasks in a distraction-free environment.

When new notifications arrive, floating bubbles appear within the minimalist clock, providing timely alerts without disrupting the user. Users can simply swipe up to expand the app list, simplifying the operation process.

The new voice assistant is based on a large AI model architecture, capable of recognizing more complex and ambiguous commands. It currently supports common scenarios such as intelligent ticketing, stock monitoring, voice-based image search with caption generation for Xiaohongshu (a Chinese social media platform). For example, users can simply say, "Book me a high-speed train ticket to Shanghai next Monday," and the system will automatically open the 12306 app, retrieve relevant ticketing information, and provide a range of ticket options. Users can then confirm their choice via voice command.

The AI voice-based image search and caption function is equally convenient. Users can say, "Post this picture of the Nubia Z70 Ultra to Xiaohongshu with a caption celebrating Nubia's 12th anniversary," and the system will automatically select the image and generate an appropriate caption, including interesting emojis, significantly improving the efficiency of publishing content on social media.

In terms of AI screen understanding, when users find a favorite store on platforms like Xiaohongshu, they only need to say, "Navigate here," and the system will automatically recognize the address information on the page and use the navigation software for route planning.
