Analytical opinion About Nubia Z20

Nubia z20, screen

In 2019, finally, flexible screen mobiles arrived that will give us many joys in the coming years by allowing different designs. Still, we have also seen full-screen mobiles without a notch that hide their cameras in modules or bets such as that of LG or ZTE for offering two independent displays. In this article, there will be an analytical opinion About Nubia Z20.

The Nubia Z20 also offers two screens, but in the body of a mobile, that seems normal. In front, we have the main one, in which there is no notch, and behind it is another fully functional screen. Before continuing with our analysis of the Nubia Z20, we leave you its characteristics:

  • Conclusions: as an experiment, it is not bad

Nubia Z20, A smart design that plays in the big leagues

As we say, when we talk about design, we tend to stick to a kind of standard for a long time. Aluminum frames, front with notch/hole / pop-up camera, glass rear, screenprint on mid-premium / high-end mobiles. and little else.
The Nubia Z20 is a more traditional mobile phone that has a front with curved sides in which, the truth, the screen could have been used a little more. Both the chin and the upper part are somewhat broad, and we have an 84.7% screen/body ratio. Not bad, but considering there is no notch. They could have stretched more. What is on the top is a notification LED.

The design of the set is very premium. The back also has curved sides (even if it is the glass, not the screen), we have another handset in the end if we decide to call using that screen and something that suits the Nubia logo at the bottom. In short, it is a mobile that, as soon as it falls into the hand, gives the feeling of being very premium. It is attractive, elegant, weighs its own with 186 grams, and we cannot blame Nubia for anything in this regard.

Two screens, but not twice the fun

Now, although the terminal has a couple of additional benefits, the sharp point is the screen. Nubia already toyed a few months ago, in China, with the idea of ​​mobile with two screens, and with the global launch of the Z20, they demonstrate their commitment to that idea.

Let’s start with the one we are going to use 95% of the time, the front. We are facing an AMOLED panel with a resolution of 2,340 x 1,080 pixels. It is 6.42, “which gives us 401 pixels per inch and an aspect ratio of 19.5: 9. So far, everything normal for the mobile of this range. The screen has a good color representation, contrast, and saturation that not exaggerated and perfect response. Still, it is true that to have the best experience, and we must put the screen in “Colorful” mode, the only setting beyond the night light.

Now how about the rear screen? Here there is more to comment, and not good, precisely. We have a 5.1 screen with an HD + resolution that translates to 1,520 x 720 pixels and a density of 330 pixels per inch. That figure, today, is scarce, but the truth is that with the size of the screen (and what we are going to use it), it is more than adequate.

Later, when we talk about Android 9, we will go into more detail, but we have used this screen for three things:

Have the other app running on that screen.
Take photos of a person while looking at the screen, like a mirror.


The brightness is not that much, either, and although the deviation is not too high (12 lux is good news considering that we are dealing with a secondary screen), we have an average brightness of 539 lux. In addition to the fact that the part reflects a lot, the outdoor viewing experience is not the best. As we say, it can use for everything, but it is not the best experience. Ah! The mobile phone case includes a transparent silicone case, and the screen also responds with the case on, although the experience is worse.

TOP performance with Snapdragon 855+ and 8GB of RAM

Before we see how Android nine is with Nubia customization, let’s talk about performance. And here there are no surprises (which we appreciate). We are facing the Snapdragon 855+, the most powerful processor on the market for Android, until the Snapdragon 865 extended throughout this year. It is an eight-core processor that can cope with everything and is accompanied by 8 GB of RAM.

There is no problem when opening many applications, playing all kinds of demanding games, or using heavy apps.
The company has decided to introduce GameSpace mode. A game mode that is one of the strengths of the Red Magic 3S, and that, with this processor, makes a lot of sense. In this game mode, we can see different parameters of the terminal. Configure notifications so that they do not jump while we play and force the SoC to go to everything it “gives” to achieve maximum performance in games … or play saving battery if the situation requires.

Android 9 with smart customization that stays halfway

Now then, let’s go to the exciting thing, since the gross power is useless if there is no control of it, and there the operating system comes into play. We have Android 9 on hand with a Nubian customization layer that can be summed up as pressure-sensitive edges (to capture the screen, for example) and switching between screens, as well as the game mode and the dark theme of the system.

The rest of the system is relatively clean, and the Chinese company has not put many hands in its customization. It allows us to enjoy a very fluid and familiar operation for those who come from Android One, for example. Now, as you can see in the images, many menus are translated; they arrive entirely in English (and not elaborate menus, but everything that involves extra customization) and some warning has come to jump in Chinese.

In short, does it work well? Yes, the system is fluid, no applications have closed to us in these weeks of analysis of the Nubia Z20, and the system is reliable. Still, they have fallen short with the customization in some aspects, and that half of the menus come in English. It is unforgivable. By the way, if you are one of those who use Discover a lot. It is not available on the Nubia Z20.

Three cameras that serve for everyday life and portraits (and that do strange things)

The photographic section is one of the most decisive points when buying a smartphone currently. The Nubia Z20 has three cameras that used as primary and front cameras, something that, a priori, guarantees higher quality portraits than on smartphones with a much smaller camera on the front. The primary sensor is 48 megapixels with optical stabilization and f1.7 aperture comparable to a 26mm universal pitch. The telephoto lens offers 3x optical zoom and has 8 megapixels f2.4. The third camera is a 12-inch wide-angle camera with 16 inches and a pixel size of 1.0 µm. The original pixel size is smaller, at 0.8µm

That said, it is the only example of the reel, but it is the first time that I take a photo with current mobile phone, thinking that it will be fine. And such a strange result comes out. It is not a lack of clarity, and it is that, directly, has interpreted the scene as wanted. Now, what about the other sensors? The one I liked the most is wide-angle. The performance (by colors and sharpness) is excellent, and it is a sensor that you can tinker. Of course, as you can see, the colors vary from the primary camera to the wide-angle, as well as saturation and contrast.

Also, the “suspicions” that it is a digital zoom are confirmed when we see the metadata of the camera, and we realize that the focal length is 5x and 10x identical to that of 3x, which shows the digital zoom.

In the video section, we can record at 4K and 60 frames per second, but also at 8K resolution 15 fps experimentally with HDR activated. 8K video is. As a demonstration of “strength,” since it is not useful to record at 15 fps. For the video, there is no stabilization, so we must be quite still. We leave you examples at 1,080p60, 4K60 and 8K HDR:

As we say, with good light, it is a camera that complies, but there are too many conditions when that light falls a little. It is not an all-terrain camera as in other devices. And It shows that the company has to fine-tune the software. It is a great idea to use the primary camera as the front thanks to the second screen, and the mirror mode of the same is also perfect for the model to pose correctly. Still, just like in the Android customization software, it gives the feeling that they are half done.

Functional autonomy and fast charge

The camera is essential in the mobile of a specific range, but also the battery, and we have good news. 4,000 mAh with 27 W fast charge that offers us enough autonomy for a day of intensive use or a day and a half if we use it for social networks and little else.

The charging time is one and a half hours, the typical result of the included charger. 50% reached in about 37 minutes. The performance is beyond doubt and can cope with everything, and the sound. Although it has no customization, it complies to watch videos and play. However, the cameras are not up to what we expected, especially since the experience when taking photos using the second screen is not as good as it should be due to the yellowish tone of it.

For the rest, ‘kudos’ to a Nubia that has thrown itself into the pool with a risky terminal. Although it has not come out round in all the sections, at least it has amused us. And, yes, it is fun to have a technological piece in hand that is out of the canon.
