To learn more about the Nubia Z20, you can read our detailed review, which contains a detailed description of the features and capabilities of the phone.

Nubia Z20 smartphone review

Usually, even before the official presentation of smartphones, a lot of insider information was provided about their appearance, parameters and characteristics, which completely coincides with the official description.But the Nubia Z20 is somewhat different, and, unfortunately, there is not much information about the new product, plus it has some contradictions. Therefore, some parameters and characteristics in the review may differ from the data that will be provided after the official presentation of the novelty.

Parameters and characteristics

Memory and cost

Nubia Z20 will not have an additional slot for memory expansion, but this is not necessary, since the phone will be available in one of three options for RAM - 6, 8 or 12 GB, as well as in one of 3 internal memory - 128. 256 or 512 GB.

As far as we know, the 6 GB + 128 GB variant will cost about $500, 8 GB + 256 GB will cost about $ 600 and the third version 12 GB + 512 GB will cost about $ 800.

cameras

The exact location and number of cameras is still unknown. From Nubia, various versions of images of the future flagship leaked into the network.Initially, it was assumed that a 16 megapixel front camera would be installed on the main screen, and a dual-module rear camera with a resolution of 48 megapixels and 16 megapixels on the secondary screen.

But the latest insider information indicates that the front camera will be absent, and a triple module will be located on the rear side in a horizontal position, presumably with the following characteristics:

1. The main camera with f / 1.6 aperture, ½ sensor, 26 mm wide and 0.8 micron pixel will have a resolution of 48 megapixels;
2. The second, with a resolution of 16 megapixels, will most likely be expressed by an ultra-wide-angle lens;
3. The third with 8 megapixels will work as a telephoto lens.

Two LED flashes should be placed on the sides of the triple module.

The specs indicate that the lack of a front-facing camera won't upset consumers, as the triple dual-LED flash module on the secondary screen will capture high-quality self-portraits.

Based on several photos posted on the Internet, taken by the co-founder of Nubia in Chile, we can draw conclusions about the incredible photo capabilities of the cameras of the device. Photos indicate the presence of a super night mode. When applied, the user will be able to get a bright and clear photo, both in poor lighting and at night. Also, the photographs taken speak of macro mode. The photo captures a leaf, when using macro photography, you can clearly see the smallest details.

Camera functionality:

• professional video mode and digital zoom;
• face recognition function and automatic flash;
• continuous shooting mode with HDR dynamic range;
• exposure compensation setting and LED flash;
• autofocus and panoramic mode;
• touch focus and phase detection;
• optical image stabilization.

Interesting Facts

Nubia is partnering with Chinese Academy of Sciences Doctor Dan Likai. The doctor captured the solar eclipse that took place on July 2 in Chile, on the Nubia Z20. Dan Likai admired the high quality of the photographs taken and noticed that the cameras in the new device have improved significantly compared to the previous model.

Nubia Z20 also showed a high level of capabilities, capturing the Milky Way. The photo taken indicates that the camera phone will have a hybrid, intelligent zoom function without quality loss.
An example of a photo of the Milky Way and a solar eclipse can be found on the Internet.

Video Format

Particular attention should be paid to support for 8K video recording. Nubia Z20 is the second phone in the world to support this feature. It is noteworthy that the first smartphone that supports 8K is also a device from Nubia - Nubia Red Magic 3.

But, as the president of Nubia said, Red Magic 3 will lose somewhat to the Z20. Unlike Red Magic 3, which supports 15 frames per second, the novelty will be able to record more frames. But Ni Fei did not specify the exact number. The data will be classified until the official presentation.

Design and display

Front Panel

The main feature of Nubia Z20 is the presence of two screens that will instantly attract the attention of others. The front side is a 6.42-inch capacitive OLED display, which occupies 84.8% or 101.2 cm2 of usable surface area. The resolution of the main screen is 1080 by 2340 pixels. The smartphone can comfortably fit in the palm of your hand, as the aspect ratio is 19.5 to 9.The screen is protected in the form of Corning Gorilla Glass, the version of the protective glass is currently unknown. The front panel will have proximity and light sensors, and as for the front camera, as it was written above, most likely it will be absent.

Back panel

The secondary screen on the back of the device also has a resolution of 1080 by 2340, but a smaller diagonal of 5.1 inches. The screen is protected by third-generation Corning Gorilla Glass. The pixel density per inch of both displays is 401.

In the previous model Nubia X, manufacturers were able to achieve the effect of an invisible screen when it fades. Visually, it seemed that it was just a glass back panel. Most likely, the Nubia Z20 will follow the same technology.

At the top of the back panel, in a horizontal module, there are 3 cameras, on the sides of which two LED flashes are installed. Below is the company logo.

Side faces

The ends of the smartphone are made of metal. Most likely, Nubia Z20, like Nubia X, will have two fingerprint scanners, which will be located on the right and left sides, in the middle. The presence of two scanners will allow you to comfortably unlock the main and secondary screens of your smartphone. Also, when you click on two scanners at the same time, there is a transition from one working screen to another. In the previous model, the scanner read speed was 0.1 second. This indicator is also new.
Also on the left side is the power button and the volume button.

Processor and video card

Nubia Z20 shows incredibly high performance, because "under the hood" is a smart Qualcomm SDM855 Snapdragon 855 Plus.The mobile platform is purpose-built for gaming with enhanced graphics, reliable connectivity and high performance.
