Some users believe that one of the weirdest decisions made by smartphone manufacturers is to create devices with two screens. Typically, the second display is located on the rear panel. It turns out to be small and not very functional. This impression is first produced by the gadget of Nubia. For the final formation of our own opinion, we will consider in more detail all its advantages and disadvantages.
Design and specifications
The Nubia Z20 smartphone received a main 6.42-inch AMOLED display with an aspect ratio of 19.5: 9 and a resolution of 2340 ? 1080 pixels, the density of which is 401 ppi. Its brightness is 600 nits. For protection from chips and scratches, the presence of tempered glass Gorilla Glass 5 is provided.
The second screen has a dimension of 5.1-inches and an AMOLED matrix. Its aspect ratio is 19: 9, resolution - 1520 ? 720 pixels, 330 ppi, brightness up to 330 nits.
At the heart of the hardware stuffing of the device is the Snapdragon 855 Plus processor, supported by the Adreno 640 GPU. Together with them works 6 8 GB of RAM and 128/256/512 GB of internal memory.
The photo capabilities of the smartphone are represented by a triple camera. She received sensors with a resolution of 48, 16 and 8 megapixels. The second here acts as an ultra wide angle lens, and the third is a telephoto lens.
Due to the presence of an additional display, there is no need for a selfie camera. The second screen serves as a good viewfinder, allowing you to take good pictures from the opposite angle.
The Nubia Z20 is equipped with a 3900mAh battery and six sensors. Communication is provided via Bluetooth 5.1, Dual GPS, Wi-Fi 802.11 b / g / n / ac, USB-C.
The OS is Android 9 Pie.
Weighing 186 grams, the device has the following geometric dimensions: 158.63 ? 75.26 ? 9 mm. It is sold in blue and black cases at a price of 35,000 rubles.
Second Display Features
The main purpose of the second smartphone screen is to take selfies and video chats. These functions work well here, although some people will not like the format of the back panel and the size of the displayed image. Lower resolution and lower brightness affect.
Some users use it to constantly display the current time and display notifications. The settings allow you to mirror the main display or set the original splash screen. It is also possible to apply an additional extension here, displaying one of the applications on an additional screen.
A nice addition to the management capabilities of the smartphone is the presence of two power buttons with built-in fingerprint scanners. They are located on both sides of the body. With their help, you can activate any of the screens, regardless of which one is currently being used.
Lefties will also like this functionality.
The developers used the well-known Sony IMX586 as the main sensor of the camera. It is capable of delivering images with a resolution of 12 megapixels. Optional lenses help you get a variety of shots.
Most of them come out underexposed, but good quality photos can be taken with sufficient lighting.
Self-portraits are especially worth noting. They come out better than most smartphones with single selfie cameras. The wide mode allows for creative shots and group selfies.
The Nubia Z20 received software that can be called almost pure Android. The advantage of using it is the presence of a restrained interface, without admixture of elements from iOS and with several functional additions.
A feature should be considered the absence of viruses and heaps, the ability to compress the bottom of the screen. This allows you to select the application you want.
For some advanced users, Nubia's shell may seem too simple or even backward. The undoubted disadvantage here is the ability to use only one way of navigation - using a three-key pad. There are no gesture controls.
Still no dark mode, no advanced settings in the software.
The most annoying thing is that the software sometimes throws errors. Most of them involve the use of a second display. The program often activates it instead of the main one or allows quick switching between displays. This makes normal operation impossible.
Performance and autonomy
The developers have installed powerful hardware in the Nubia Z20. Here is the most advanced processor, and a sufficient amount of RAM, which does not allow us to assume weak performance of the gadget.
Sometimes it gives minor glitches, but the questions here are only about software, not about performance.
The developers claim that the battery autonomy will last for 10-12 hours of operation at maximum load, or for 30 hours of talk time on the phone. Replenish energy reserves with 27W fast charging.
The advantages of this device are a versatile camera system and powerful hardware. This is not enough, since the gadget turned out to be "raw", containing errors in the software and lacking a number of necessary functions. There is no NFC module, microSD card slot and wireless charging.
