Nubia Z20 overview: Two-face enigma

Within the age of the fashionable smartphone you do not come throughout too many concepts which might be considerably other to what maximum others are doing. That is as a result of corporations most often have a good suggestion of what applied sciences are necessary to customers, so understand how to construct their telephones. However that does not imply there are not attention-grabbing concepts available in the market.

One corporate, Nubia, turns out to reside and breathe relatively wacky concepts. In 2019 it confirmed off a peculiar smartwatch that was once additionally a mini versatile smartphone. It additionally introduced the Z20: a smartphone with two presentations and no front-facing digicam. It is full of nice specifications and is in reality to be had for an inexpensive worth. However does the two-screen revel in convey any actual further receive advantages?

Twin sided symmetry

Dimensions: 158.6 x 75.three x 9mm / Weight: 186g
Diamond Black or Twilight Blue colors
Glass and steel design

Take a look at the Z20 from the entrance and you almost certainly may not understand the rest all that exceptional. It seems like a smartphone; the standard aggregate of glass and steel, the place the entrance glass is curved on the edges.


Energy up the show, then again, and you can see that there is not any notch and no hole-punch cutout for a selfie digicam. This is, in fact, as a result of there is a 2nd display at the again, which can be utilized with the rear digicam to behave as a selfie gadget. 

That implies this telephone has narrow bezels all of the means round, with not anything creeping into the display’s area. We love that so much. As turns out to nonetheless be the case for many Android telephone makers, the ground edge continues to be chunkier than the others. This nonetheless appears to be a space that is proving tricky to shrink.

We actually just like the end of the polished steel across the edges too. The Z20 has this darkish, shiny glance to it that isn’t reasonably pitch black, however extra of a smokey gray. That is the place you can understand one thing abnormal: it has a fingerprint sensor/energy button on all sides, positioned at precisely the similar peak on each correct and left edges. To its credit score, the location is perfect for the use of with a thumb on both hand, and that makes it a in reality ambidextrous telephone that is as handy for a left-handed person as it’s for a right-handed one.


It additionally method you’ll use it simply whether or not you might be the use of the main or secondary display at the again. The use of our thumb, we discovered it additionally had a excessive accuracy price, unlocking the telephone temporarily just about each and every unmarried time, with none ‘now not recognised mistakes’.

It is in all probability now not essentially the most technologically complicated fingerprint sensor to be had now, however we perceive why it is completed this fashion. An in-display fingerprint sensor would imply it best labored on one aspect. Likewise, the use of complicated facial popularity will require, neatly, a front-facing digicam to make sense, which is not the level of this telephone’s design. It is the most efficient compromise for what Nubia sought after to reach.

Flip the handset round to look the Z20’s promoting level: that 2nd display. On the other hand, Nubia is not the primary corporate to suppose striking a display at the again of its telephone is a good suggestion. YotaPhone’s best promoting level was once the truth that it had an e-Ink show at the again of its telephone, kind-of like a mini Kindle. Chinese language producer, Meizu, additionally had a display at the again of Professional 7, aside from this one was once a tiny, color display that did little greater than display notifications and the elements.


Nubia’s way is hugely other to each, extra comparable to the Vivo Twin Show that introduced in China in 2019. Each handsets be offering a complete color, excessive refresh-rate, right kind display on their rears. For the Nubia it isn’t as giant as the primary show, however it isn’t tiny in any way, filling a just right percentage of to be had area.

Is the secondary display in reality helpful?

Now we do not thoughts corporations pondering outdoor the field. If truth be told, as tech fanatics that love to get excited about new issues, we inspire it. In the end, the very last thing we would like is for the whole thing to be precisely the similar.

After greater than a decade of essentially the use of smartphones with one primary display, there may be undoubtedly slightly of a finding out curve seeking to understand that there is a 2nd display at the again. It isn’t instinctive to turn a telephone over and use the secondary display. The one time it feels herbal is when taking selfies.

As a result of there is not any devoted front-facing digicam, the rear display turns into your selfie display when taking pictures of your self. That does imply you do not need to make use of a miles poorer digicam to take selfies – which is most often the case – in order that’s one sure to return from this fairly peculiar telephone. 


The place we do in all probability see some use for the display is with the telephone grew to become over at the table. You continue to have an always-on show going through upwards, beside the point of orientation, which is able to display you if in case you have notifications. And if you wish to test them temporarily with out the use of a large number of the telephone’s battery, you’ll transfer the display to its maximum battery environment friendly state – necessarily black and white.

So is it helpful? Sure, from time to time. Is it crucial? No, now not even somewhat bit. Whilst attention-grabbing, even after the use of it for some time, it feels find it irresistible actually does not wish to be there. What is extra, the truth that it is at the again, and most commonly being held within the hand, it temporarily will get coated with fingerprint smudges.

Media intake is hit or miss

Major display: 6.42-inch AMOLED show
1080 x 2340 solution
Corning Gorilla Glass 5
Unmarried loudspeaker

As for the main display at the entrance, that is in reality a tight panel. It is giant, vibrant, sharp and many shiny sufficient. Use it to show the precise content material and it appears to be like reasonably surprising now and then. Release a recreation like Alto’s Odyssey and the colors and element simply pops at the display to provide you with an implausible visible deal with.


Unfortunately, with Netflix, that isn’t the case: it kind of feels Nubia’s telephone can not play the very best solution at the streaming large’s cellular app, so whilst colors, gentle and shadow appears to be like just right, main points are somewhat fuzzy. And when probably the most well-liked video apps at the Play Retailer does not appear to be used optimally, it is disappointing. In a similar way, with the rounded corners, from time to time we discovered portions of the picture had been relatively bring to a halt.

Upload the truth that you best have one loudspeaker firing sound out of the ground edge and the Z20 can sound somewhat underwhelming. The loudspeaker itself is not the most efficient high quality both, the sound can get loud, however is reasonably tinny and does not have any of the bass we have now transform conversant in in fashionable flagships.

Flagship efficiency

Snapdragon 855+ processor, 8GB RAM
4,000mAh battery
128GB garage

For essentially the most section, the Z20 acts just like the flagship it’s, due to being powered by means of certainly one of Qualcomm’s maximum robust processors. It is the Snapdragon 855, the similar you would in finding in just about each and every high-end Android telephone from 2019.

What that implies is when loading apps, or gliding across the person interface, it launches temporarily and easily. Put the Z20 side-by-side with the uber clean OnePlus 7T, and chances are you’ll understand the Nubia’s lack of a better refresh-rate display although.

Like its common speediness and function, the Z20’s battery was once cast in our trying out. With a 4,000mAh capability, that is to be anticipated. On what we would believe an attractive standard day with somewhat gaming, plenty of social media, internet surfing and a few song, we were given to the tip of the day with between 30-40 in line with cent ultimate. It isn’t actually a two-day telephone, in particular now not for heavy use, however it will with ease get maximum via a complete day. 


Triple digicam gadget
48MP number one sensor, optical symbol stabilisation (OIS)
16MP ultra-wide
8MP telephoto

It nearly turns out common now to look this triple digicam gadget at the again of a Chinese language Android telephone, so it is no wonder to look a 48-megapixel number one sensor joined by means of each an ultra-wide digicam and a telephoto/zoom digicam. 


What this allows is a digicam that has the flexibility you would anticipate finding on a top class smartphone, supplying you with 3 distinct focal lengths in a single product, without a cumbersome further lenses.

Within the digicam interface, you’ll temporarily transfer between the ultra-wide 0.6x, 1x and 3x modes, with out dropping any element. There is additionally the choice of a 5x zoom and 10x zoom, however you can understand the image begins to get reasonably ‘splodgy’ if you make a decision to take it that a long way. 

Total, the consequences are fantastic. Positive, they may not blow you away with their dynamic vary, or the way in which harsh brightness is balanced out with darkish shadows, however for the on a regular basis shot, in first rate gentle, you can get greater than satisfactory effects. 


The Nubia Z20 is a superbly just right telephone, particularly at its worth level. It plays neatly, appears to be like just right, has a really perfect (primary) display, and a model of Android that is not overloaded with plenty of further bloat or a heavy customized pores and skin.

Its greatest factor, actually, is that we have now now not even discussed the second one display – as it feels fairly alien to get quite a lot of use out of it. As that is the primary promoting level right here, we fight to be allured.

Plus, there may be robust festival available in the market. At a an identical worth you’ll pick out up one thing from OnePlus and get a smoother, sooner telephone with a display – and simply the only! – that is unquestionably one of the most highest presentations in the marketplace. Nubia would possibly have two monitors, however that does not actually make it higher than one.

Possible choices to believe


OnePlus 7T 


If you need a Snapdragon 855+ provided telephone with speedy, clean efficiency and a triple digicam, you’ll get that from OnePlus. The OnePlus 7T is an implausible software, and whilst it prices somewhat greater than Nubia’s telephone, it is much more extensively to be had. 


Xiaomi Mi 9T Professional 


If worth is what is necessary to you however you continue to need nice efficiency and will care for a relatively lumpy tool revel in, the Xiaomi Mi 9T Professional is tremendous simple to suggest. It is a surprising telephone for its worth level.
