Pick your dual screen smartphone: Vivo NEX dual screen or Nubia X?

ByGB Blog Official 2019-01-16 3891

As more and more smartphone companies are exploring the idea of a full screen phone, we are seeing a wide range of creative solutions to the idea. Some have introduced the idea of the notch (which was not too well received by most design-savvy users), others have brought to life the concept of a pop lense (think the Oppo Find X and Vivo Nex) and yet others have tried out the idea of a sliding front screen (Xiaomi Mi Mix 3).

Now, we have two new phones and, with them, two new approaches to the full screen solution. The Nubia X and the second edition of the Vivo NEX are giving us not one but two screens aiming to give its users even more of the sacred display space. In this post, we are looking at the two phones side by side in the hope of figuring out two things:

Vivo NEX dual screen vs Nubia X: four screens in between two phones

The Vivo NEX dual screen Is it recently released a follow-up model to the Vivo Nex. The new model comes with a dual screen display, which means that it has screens both on the front and the back. On the front, the phone carries a 6.39-inch main display with 1080×2340 resolution and 19:9 ratio.

On the back, there is a 5.49-inch OLED screen with the resolution of 1920×1080. At the top of the back display, you will see the phone's cameras as well as a nice addition of a a ring light — a great thing to have when taking a selfie. However, apart from the superficial function of shedding more light on your face, the ring light will also glow when charging and to let you know about incoming notifications.

On the right side, there are the volume rockers and a power button for the main display while on the left you will find the second power button. The second power button will activate the device's second screen and will also put the phone into selfie mode if the camera is open.

At the bottom, you get the typical setup of a USB Type-C port, speaker grill and a dual SIM tray. At the top, the Vivo has preserved the 3.5mm headphone jack.

The Nubia X comes with a very similar arrangement: there is a  6.26-inch LCD FHD+ (2,280 x 1,080) LCD front screen and a smaller 5.1-inch OLED display with a lower resolution (1,520 x 720) on the back. The phone claims an impressive 93.6% screen-to-body ratio and, true to the claim, comes with very thin bezels.

Just like with the Vivo Nex, the cameras have been moved to the back of the phone and you will find all the standard ports and buttons.

Vivo NEX dual screen vs. Nubia X: strong specs under the hood

On the inside, the Vivo NEX dual screen is a pretty impressive phone. It's one of the few devices on the market with 10GB of RAM — true, this may be way more than the average user will need but it's definitely a nice option to have onboard.

The phone runs on the Qualcomm Snapdragon 845 processor and there is 128 GB of storage and the standard 3,500mAh battery. This, actually came as a bit of a disappointment, as we would expect a phone with two displays to come with double the standard battery power. However, as the two screens are rarely used at the same time, there should be enough battery life for everyday use.

The Vivo NEX uses Funtouch OS 4.5 based on Android 9.0 Pie, which is, by far, not the best operating system on the market — but it has its fans.

The Nubia X uses the same Snapdragon 845 processor and is available with either  6 or 8GB of RAM does the job.

But the 845 is on its final days as a flagship chip set, as Qualcomm is replacing it with the 855 in a few weeks. And you get quite an array of options when it comes to internal storage: 128GB, 256GB or a massive 512GB.

On the battery side, the Nubia X does slightly better than the NEX and comes with a heavier 3800 mAh battery — which should be enough for a day's work with the moderate use of the two screens.

Vivo NEX Dual Display vs. Nubia X: you only get back cameras

The Vivo NEX Dual Display edition comes with three cameras, all of which are located on the back of the phone. You get the setup of 12.0MP + 2.0MP + TOF 3D cameras. The clever thing about arranging all of the three cameras on one side was re-purposing the main 12MP f/1.8 cameras  alongside the secondary 2MP f/1.8 sensor for both standard shots and selfies. Plus, there is the ring light we've already mentioned above that will add extra illumination for your selfies and general shots.

The Nubia X comes with a 24-megapixel main lens with a 16-megapixel secondary one. The camera setup is impressive on paper — but we could definitely do with more light as users have been complaining about low light photo quality.

So, how useful are the secondary screens?

There are definite pluses to having two functional screens on one device:

First, you can technically be doing two things at the same time: play a game on the front of the phone while having a chat or camera open on the second screen.

Second, both phones offer easy ways for switching in between the two displays — either with physical buttons or assigned shortcuts. So, you will not be losing out on speed and productivity.

Third, having all your cameras on one side leads to same quality photos for both regular shots and selfies.

We've left the most obvious advantage of the dual display for last: you finally do get a full screen experience on the front of your phone without a distracting notch to spoil it.

So, are there any downsides?

Aside from the fact that you will be sporting a pretty fragile device (you will now need screen protectors on both sides of your phone) and the slight spike in the use of battery life, there are no obvious negatives of having two screens instead of one.

However, the main question here is this: do we actually have enough uses for the second screen to justify its existence? And this is something that, at least for now, will have to be answered individually.

Vivo NEX Dual Display vs. Nubia X: the verdict

The latest Vivo NEX Dual Display is available on GB for $739.99 while the starting price for the Nubia X is about half that. The NEX, at least for us, comes with a nicer design — and there are three cameras with a ring light (instead of just two on the Nubia X). Plus, we are pretty excited about the 10GB RAM option. With that said, you will be paying double for the upgrades.

To sum up, we definitely find the idea of a dual screen phone intriguing. Whether it is something that will catch on or remain in the folder of the "once only" design gimmicks — only the future will tell.
