Nubia Z70 Ultra In-Depth Review: A Perfect Fusion of True Full Screen, 35mm Main Camera, and Nebula AIOS

The Nubia Z70 Ultra, a flagship phone daring to be different and challenge conventions, offers a unique user experience thanks to its distinctive "true full-screen" design, iconic 35mm main camera, and intelligent Nebula AIOS. This review will comprehensively evaluate the Nubia Z70 Ultra across various aspects, including screen, appearance, imaging system, performance, operating system, and overall experience, aiming to showcase its unique charm.

I. True Full Screen: The Pursuit of Ultimate Visual Enjoyment

From notch screens to waterdrop screens and punch-hole screens, phone manufacturers have continuously explored the path to a full-screen display. Nubia, however, has chosen a different path, persistently pursuing under-display camera technology, finally achieving a stunning "true full-screen" effect with the Z70 Ultra. This phone boasts a 6.85-inch AMOLED screen with a 28001260 (1.5K) resolution and a screen-to-body ratio of 95.3%. This screen not only offers breathtaking visuals but also reaches top-tier levels in brightness, refresh rate, and color reproduction.

Its 2000-nit peak brightness ensures clear display even in strong sunlight; the 144Hz refresh rate and 2500Hz instantaneous peak sampling rate guarantee a smooth and fluid visual experience; and the 2592Hz ultra-high frequency PWM dimming effectively reduces screen flicker, protecting users' eyes. Furthermore, the Z70 Ultra demonstrates excellent bezel control, with even the chin meticulously refined for a perfect overall aesthetic.

So, how noticeable is the under-display camera in daily use? The answer is: in most cases, it's almost invisible. On light backgrounds, it's difficult to detect even at close range; on dark backgrounds, it's virtually invisible. Only under direct strong light might the camera position be faintly discernible. However, under-display camera technology is still under development, and the front-facing camera performance still has some differences compared to traditional punch-hole screen phones.

Although Nubia has significantly improved selfie image quality and reduced the smearing effect through algorithm optimization, there's still room for improvement in detail. It's worth noting that setting the beautification function to its lowest level yields more realistic selfies. Overall, the Nubia Z70 Ultra's under-display camera technology has reached a high level, striking a good balance between pursuing ultimate visual effects and practicality.

II. Exterior Design: A Unique Aesthetics of Square and Robustness

The Nubia Z70 Ultra continues its classic square and simple design style, with the iconic "red ring" and "small red dot" still prominently featured on the back. Commendably, the Z70 Ultra's camera deco uses an integrated glass design, enhancing the overall sense of unity and creating a more harmonious visual effect. Compared to its predecessor, the Z70 Ultra's frame has transitioned from sharp right angles to a slightly curved design that better fits the palm, significantly improving the grip.

The signature customizable sliding key has been moved to the upper left side of the phone, allowing users to set it to various functions such as photography, mute, or game mode according to their preferences. Its original position is now occupied by a dedicated camera button. A light press achieves focusing and metering, a hard press takes a photo, and a long press activates burst shooting, providing a feel very similar to a traditional camera. Overall, the Nubia Z70 Ultra's design is unique and robust, undoubtedly highly attractive to users who prefer a square style.

III. Imaging System: The Stubbornness and Persistence of the 35mm Main Camera

In an era where flagship imaging phones are increasingly adopting one-inch large-sensor main cameras, the Nubia Z70 Ultra insists on using a custom 35mm main camera. This is a unique persistence, reflecting a unique understanding of photographic art. The 35mm focal length is recognized in the photography world as a humanistic focal length; its field of view is closer to what the human eye sees, better highlighting the subject and making the photo richer. Whether for street photography or portraits, it has more advantages than the mainstream 23mm focal length.

Compared to other manufacturers' 24mm main cameras, the Nubia Z70 Ultra's 35mm main camera, when shooting the same scene, can get closer to the subject, resulting in a purer and easier-to-shoot image. This reflects Nubia's unique insight into photographic artnot blindly pursuing parameter stacking but focusing more on the actual shooting effect.

The Nubia Z70 Ultra's imaging configuration is as follows:

• Main Camera: 50MP, 1/1.56-inch CMOS, f/1.59-f/4.0 variable aperture, OIS optical image stabilization.

• Telephoto: 64MP periscope telephoto lens, OIS optical image stabilization, blue glass rotary coated IR filter.

• Ultra-wide Macro: 50MP AF ultra-wide macro lens, supporting 2.5cm macro shooting.

In actual shooting, the image quality of the Nubia Z70 Ultra is almost impeccable. The 35mm main camera has sufficiently high resolution, and the color style has a moderate saturation, accurately reproducing the colors of the scene. In complex lighting conditions such as backlight, its highlight suppression capability is also excellent, avoiding overexposure or blackouts. The advantage of a large aperture is particularly evident in close-range shooting, with excellent background blur.

The telephoto lens's performance is also satisfactory, with clear and rich details in distant objects and natural color transitions. Thanks to Nubia's optical super-resolution algorithm, image details are further enhanced. The 13mm ultra-wide-angle lens excellently handles the task of a 24mm focal length, with good distortion control and excellent color performance. The Nubia Z70 Ultra's humanistic street photography mode is also worth mentioning. Users can customize the camera button to quickly activate this mode, offering fast capture speed and smooth operation. This mode also allows users to adjust parameters such as color, sharpness, white balance, and EV to meet the needs of professional users.

In summary, the Nubia Z70 Ultra's imaging system is unique. The combination of a 35mm main camera, a 64MP telephoto lens, and a 50MP ultra-wide macro lens provides users with ample creative space, and its overall imaging capabilities are unique in the current market.

IV. Performance: The Powerful Driving Force of the Qualcomm Snapdragon 8 Gen 2
