Vivo V23 & V23 Pro Hands-On: Color-changing back and 50MP selfie camera helps these phones stand out

Vivo’s V series is known mostly for a couple of things: its prolific, twice-a-year release schedule, and selfie camera-centric hardware. This is a line that was pumping out 20-megapixel front-facing cameras when everyone else was on 8MP; and 32MP and 44MP selfie shooters when other selfie cameras were shooting with 12MP.

The latest update, the V23 series, ups the numbers game again, with both the V23 Pro and V23 standard model packing a dual-selfie camera system headlined by a 50MP, f/2.0 selfie camera plus an 8MP ultra-wide selfie lens. This time out, there’s one more selling point to differentiate the new devices from the sea of mid-tier smartphones: a color-changing back.

About this hands-on: Vivo sent me both the V23 and V23 Pro for testing. Vivo did not have any input in this article.


Vivo V23 series: Hardware and Design

The Vivo V23 and V23 Pro are mid-tier phones that have gone on sale first in India for ₹29,990 and ₹38,990 respectively, these prices convert to about $403 and $524 respectively. Vivo has already confirmed the devices will hit other parts of Asia including Malaysia, Thailand, and Europe “soon.”

As mentioned, both phones have the same front-facing camera system, as well as identical 8MP ultra-wide and 2MP macro sensors on the backside. They also run on the same software and have the same color-changing back technology.

Let’s talk about this back first. This is no mere gradient-colored glass coating that reflects light differently depending on the angle. Instead, this tech uses a new type of glass (Fluorite AG glass), which, when hit by ultraviolet rays goes through a chemical process that results in color change. By default, this color is orange, but when it absorbs enough UV light it transforms into this blue-ish green.

Because the glass plate is really undergoing pigment changes from absorbing light, this means you can play with the change by covering parts of the glass, giving the phone tanlines, so to speak. I was able to get an X on the phone by covering it with a piece of paper.

This is no mere gradient color coated back; instead the back really changes colors

If you’re more creative, you can get more intricate patterns on the phone like this promotional image provided by Vivo.

If the color changing back is not your cup of tea, the V23 series also comes in a second color, a more subtle standard black that just stays black.

Display, processors, and main cameras

The major differentiating factor between the two phones comes in chassis design: the V23 Pro has a typical (in the Android space) curved display that blends into a narrow frame. The standard V23, meanwhile, has a boxy design with a flat front, back, and sides — yes, it’s the iPhone 12/13 design.

Vivo V23 Pro

The Vivo V23 Pro has a familiar curved screen.

I generally like curved screens — I find them to offer a better in-hand feel and a more immersive screen — but I must say, the boxy design of the V23 is a breath of fresh air, mainly because I have handled at least 100 devices in the past few years with the V23 Pro’s body type.

And unlike Apple, which keeps the sides entirely flat with hard corners, Vivo gave the V23’s corners a subtle chamfered edge, which combined with the V23’s narrower width, makes for a more comfortable in-hand feel than the iPhone 13 Pro.

The Vivo V23 Pro has a slightly larger 6.56-inch screen than the V23’s 6.44-inch, but because the Pro curves at the sides, the phone’s screen size feels identical. Both panels are OLED and refresh at 90Hz. They look vibrant enough, with a 1080 x 2400 resolution, but neither get as bright as what we’ve come to expect from flagship Android phones. And yes, the presence of a notch in 2022 is very unsightly, but Vivo has indeed put a lot of hardware into the front-facing system. This is a notch with an actually useful function.

The Pro model is powered by a MediaTek Dimensity 1200 SoC while the standard model gets a Dimensity 920. Both of these chips are more than powerful for day-to-day casual smartphone usage, though they’re clearly not on par with a Qualcomm Snapdragon 888, let alone the Snapdragon 8 Gen 1 that will begin populating the Android flagship space soon.

The V23 Pro’s main back camera also gets a bump over the standard V23: a 108MP, f/1.9 shooter versus the 64MP, f/1.9 sensor on the standard V23. For the most part, both main cameras are solid shooters at their price range, but the Pro’s sensor grabs better dynamic range if shooting under more challenging lighting conditions.

Selfie cameras

The star of the show, ultimately, is the front-facing camera system. When I tested the last two V devices (V20 and V21), I found their selfie cameras did, indeed, produce more vibrant, better-lit, and balanced selfies than top-tier Apple and Samsung phones, particularly when shooting under challenging conditions like directly against harsh sunlight.

The Vivo V23 series' selfie camera does a better job than the iPhone when it comes to finding proper exposure and balance

I am, unfortunately, stuck in quarantine right now so I only have limited scenes and lighting conditions under which to test the cameras, but once again we can see that the Vivo V23 series’ selfie camera does a better job than the iPhone when it comes to finding proper exposure and balance. This shot was challenging, I am shooting with harsh backlight coming in from half of the frame behind my head, while the other half is darker, covered by a curtain. So the selfie camera has to find exposure for not just my face, but the window, and also the computer screens. The iPhone 13 Pro blew out the light from the window completely.

In dark conditions, the Vivo V23 selfie cameras also pulls in slightly more light thanks to pixel binning.

The ultra-wide selfie camera gets the job done in getting more into the frame, but details are noticeably softer compared to the 50MP main camera.

There are a lot of extra selfie camera features, like a dual front-facing flash that can serve as fill lights, a myriad of portrait styles and beautification filters, and the ability to record 4K/30 selfie videos. It’s a bit much for someone like me, to be honest, and I have never been a fan of the heavy beautification filters that can whiten my skin, make my nose slimmer, smooth my skin, etc. However, there’s no denying there’s a major chunk of the population that is into these things: just scroll through TikTok or Douyin (the Chinese version of TikTok) for a few minutes and you’ll come across dozens of videos of people clearly using heavy filters. There’s a market and Vivo is catering to it.

Vivo V23 series: Software

Both the V23 and V23 Pro run Android 12 with the company’s own FunTouch 12 software skin on top. The software experience is fine. FunTouch 12 has improved by leaps and bounds compared to years past, fixing a lot of weird quirks (remember when Vivo’s software used to separate the notification panel from the toggle buttons?). Some of Android 12’s visual traits, like the rounded corners of notification cards are here, as well as crucial improvements like status bar alerts whenever an app is accessing the phone’s cameras or microphone.

All the extra customization options that BKK phones have offered for years are still here, such as screen-off shortcut gestures to launch apps, three-finger swipe down to grab screenshots, and three-finger swipe up to launch split-screen mode.

Overall the phone behaves the same as previous Vivo phones, which means the software is responsive and zippy. Android purists will probably still dislike the aesthetics.


Vivo V23 series: Early Impressions

Vivo’s V series has always been slightly overpriced for what they are — for around the same price $400-$500 price range you can get a Qualcomm 800 series SoC in some rival devices, and the existence of the notch is an eyesore for me.

But the fact that Vivo keeps pumping out these V phones every half a year means there’s clearly an audience for these phones that place selfie camera performance and shiny looks above everything else. And in today’s increasingly selfie-obsessed social media culture, a phone that packs all the bells and whistles into a front-facing system should have appeal with the younger crowd.

I do think maybe it’s time for Vivo to consider slowing down its V series release cycle. My first time testing a Vivo V phone was in February of 2017, with the V5. So in not even four full years yet the series has jumped to number 23! At this rate, we’ll be on the Vivo V100 in a couple of years. In the last calendar year alone, I have tested the Vivo V20, V21, and V23 and each one only brings iterative upgrades over the previous model. Vivo’s doing some very exciting things on the flagship front — the Vivo X70 Pro Plus is in my opinion the best camera phone of 2021 — it’s time for the V series to take a break until more major innovations come along.

OPPO Find X5 Pro specifications and real-life images leaked

When Qualcomm unveiled the Snapdragon 8 Gen 1 chipset back in December, OPPO promised it would unveil a Find X phone with the new chipset in Q1 2022. As per various recent leaks, it appears the phone will be called the Find X5 Pro and would succeed the last year’s Find X3 Pro. While OPPO hasn’t shared much about its upcoming flagship, a fresh leak has now revealed some of the probable specifications as well as real-life images of the OPPO Find X5 Pro.

Real-life images and specifications of the OPPO Find X5 Pro come from CoolAPK member Andy001231 (via @yabhishekhd). While we already got our first look at the phone’s design through leaked renders shared by OnLeaks a while ago, these real-life images give us a better idea as to what to expect from OPPO’s 2022 flagship. The images confirm that the phone would indeed pack the MariSilicon X chipset, OPPO’s own chipset to handle image processing. Interestingly, we can also see the Hasselblad logo on the back, which confirms OPPO has partnered up with the Swedish camera maker to tune the phone’s cameras.

As per the leak, the OPPO Find X5 Pro will feature a QHD+ AMOLED LTPO display with a 120Hz refresh rate. OnLeaks previously said the display size would be close to 6.7-inches. On the back, the Find X5 Pro is said to feature a triple camera setup consisting of a 50MP Sony IMX766 primary shooter with OIS, a 50MP IMX766 sensor, and a 13MP S5K3M5 sensor. The phone will reportedly pack a 5,000mAh battery with up to 80W fast wired charging support and 50W wireless charging support.

The Find X5 Pro will likely be joined by vanilla Find X5. It’s rumored to be powered by MediaTek’s flagship Dimensity 9000 chipset.

We don’t know when OPPO plans to release the new Find X5 lineup. We expect to learn more about OPPO’s upcoming flagship lineup in the coming weeks. As always the new phones will likely debut in China first, before making their way to international markets.

QD-OLED Explained: What you need to know about the next big innovation for TV and Monitor displays

When it comes to unadulterated picture quality, nothing quite matches up to the crispy deep blacks of an OLED TV mounted within a dimly lit showroom. That descriptor “dimly lit” is important, because take it out in the living room and the stellar contrast of an OLED can be drowned out by reflections. In these conditions, OLED is arguably outperformed by the competing display types that get brighter. That is to say, OLED TVs are not unequivocally superior in all aspects — the technology has its disadvantages, and it’s constantly being iterated over to combat its shortcomings.

Taking CES 2022 by storm, the next big thing in the advancement of OLEDs is what Samsung Display calls QD-OLED, or Quantum Dot OLED. The display company claims that new TVs which use this technology will be brighter, more colorful, and have better viewing angles than conventional OLED TVs. Another exciting development is that this technology won’t be restricted to just TVs, but it will also make its way towards PC monitors — a first for consumer OLEDs sized for actual desks.

This new variant of OLED adds a quantum dot layer to the display stack, a technique that had previously only been used on LCD panels (via QLED). The purpose of these quantum dots is to produce highly saturated subpixels without using an organic high-purity light source of the same color, which are often costly or inefficient. Another method to accomplish this is by using color filters, which is what OLED TVs have been using up until now.

What’s the difference between QD-OLED and older OLED?

To explain this, we first must understand how previous OLED TVs are structured. OLED is an umbrella term that can house various subsets of technologies within. But when marketing uses the term “OLED” for TVs, they are more often than not referring to W-OLED.

For the past decade, LG Display has held a monopoly in the panels used for OLED TVs. These panels were all W-OLED displays that use an RGBW pixel structure, meaning that each pixel is made up of four different-colored subpixels: red, green, blue, and white. However, at its core, each subpixel is actually a white subpixel (hence the term W-OLED), and colored subpixels are achieved with a color filter that blocks out parts of the white light spectrum to produce red, green, or blue. Because light is being subtracted from the light source for the three colored subpixels, this pixel structure is not the most efficient, and it’s the reason why an extra white subpixel is needed. The fourth white subpixel does not have any color filter, and its purpose is for improved efficiency and brightness.

Quantum dots, on the other hand, convert a light source from one color to another, and almost none of the original light source is wasted in this conversion. Instead of starting with a broad white spectrum for each subpixel and stripping away parts of it with color filters, QD-OLED starts with a simple blue light source and converts it into high-purity red and green subpixels while leaving the blue subpixels untouched.

Top: Breakdown of QD layers (source: Samsung Display). Bottom: Light spectrum of QD-LCD vs W-OLED when displaying white. Quantum dots allow for narrower light spectra, which produces higher color saturation. The green and red peaks are derived from passing high-energy blue light through a quantum dot layer, and each peak is associated with its own colored subpixel.

With this efficient method, a fourth white subpixel is not needed, and QD-OLED can make use of a normal RGB pixel structure. One of the disadvantages of current W-OLED TVs is that relying on the extra white subpixel for additional brightness lowers the maximum color saturation as the display nears its peak brightness; the color volume is further reduced since color filters lose effectiveness at high brightness. QD-OLED, on the other hand, can maintain full saturation up to the maximum white level of the display. Additionally, without a fourth subpixel, the RGB subpixels can be made larger to fill the extra space, increasing their luminous output.

Why use a blue light source?

In the visible light spectrum, blue light has the shortest wavelength among red, green, and blue; thus it has the highest normalized energy. The quantum dot layer can essentially confine the higher energy of the blue light down to red or green light, but the opposite is not possible — you cannot use lower-energy red or green light to create blue light.

Why not just use true red, green, and blue light sources? Why go through all this trouble?

The biggest reason is to increase the life expectancy of the display panel. When you’re paying top-dollar for a TV, you probably want it to last a long time. Organic light sources inevitably grow dimmer over time, and different materials will decay at different rates. When a combination of light sources is used, such as with an OLED that uses individual red/green/blue emitters, the varying rates of emitter decay eventually cause the color rendering of the display to drift. For example, many displays will begin to show whites that tint towards yellow over time. Both W-OLED and QD-OLED are display designs geared towards minimizing this effect.

If we take a deeper look inside an existing W-OLED panel, we would find that the white subpixels are actually made up of multiple light sources. Initially, these subpixels were made up of blue LEDs together with a yellow phosphor, but LG Display moved on to using a combination of red, green, and blue emitters to create the white subpixels. These various emitters are mixed and sized in proportions that ensure they would all decay near a constant rate, leading to minimal color shift over time.

What about OLED burn-in?

With QD-OLED, all of the subpixels are backed by the same blue light source, so color shifting should be next to non-existent. However, blue organic materials generally have shorter lifespans compared to red and green materials, so the subpixels in QD-OLED may actually dim faster than W-OLED over time✝. This may also mean that QD-OLED could be more prone to burn-in, which occurs when parts of the display have aged noticeably more (or less) than their surrounding. Of course, we’ll just have to wait and see if this becomes an issue.

✝ One nuance here is that the RGB subpixels of QD-OLED can be made larger than in the RGBW structure of W-OLED. Larger subpixel areas improve emitter lifespan.

One other fundamental OLED design is the PenTile subpixel matrix most commonly found in smartphone displays. In principle, it works similar to how W-OLED packs its white subpixels: with a combination of red, green, and blue emitters in varying numbers and sizes so that they decay more uniformly. More specifically, the PenTile design is more abundant with smaller green subpixels since they’re the most efficient, while the blue subpixels are made much larger to lengthen their shorter lifespan.

So, is QD-OLED better than W-OLED?

Now that we’ve covered some fundamentals, we can challenge the obvious question:

Will QD-OLED be better than our existing W-OLEDs?

And the answer is… most likely! Without just re-iterating the marketing material that Samsung Display has released, we find that QD-OLED offers a clear advantage in light efficiency over W-OLED, and the standard pixel structure that it enables allows for higher color volume for HDR and for high-brightness users. The precision of quantum dots also allows for more saturated colors compared to the use of color filters, leading to higher coverage of the Rec.2020 color gamut.

Additionally, QD-OLED omits the polarizer layer, which is conventionally used to reduce reflections at the cost of blocking some of the display’s own light. Samsung Display tells us that the panel structure of its QD-OLED has an inherent advantage in handling reflections, so it’s confident that it can remove the polarizer, which should yield some extra display brightness.

Samsung Display also tells us that their quantum dot conversion emits light omnidirectionally, resulting in lower brightness loss when viewing its TVs at an angle. Existed W-OLED panels already have astoundingly uniform viewing angles, but the display company is advertising its QD-OLED to perform even better

Okay, I want one. What QD-OLED display can I buy right now?

Right now, only Samsung, Sony, and Alienware have something to show for this new tech. At CES 2022, Sony unveiled its Bravia XR A95K, a 4K QD-OLED TV which will initially come in 55″ and 65″ sizes by the end of 2022. For the PC gamers, Alienware debuted a first-of-its-kind consumer OLED gaming monitor — and by this, I don’t mean a TV disguised as a monitor. This 34-inch ultrawide display was a long-awaited reveal that finally brings OLED technology to the PC world at a popular, practical size. Both these screens will use QD-OLED supplied by Samsung Display, which should give LG Display a run for its money.

What’s most important is that Samsung Display pioneering this new technology introduces the company as a new prime competitor in the OLED market alongside LG Display. Initially, QD-OLED won’t come cheap — these new displays will likely start out much more expensive than W-OLED. But hopefully, after the tech begins to mature, we should see this competition driving OLED prices down across the board. We may also see QD-OLED becoming cheaper than W-OLED in the future, as it relies on only blue organic material instead of the myriad that LG Display has to source for its W-OLED.

Looking into the future, the next natural progression of OLED is to take out the organic materials entirely, leaving us with an LED display of a different kind. OLED is heavily limited by the effectiveness of the blue organic material, so synthesizing an alternative light source opens up the gates to a whole new generation of screens. Out in the visible horizon, Samsung Display has been working on yet another display tech called QNED, which stands for Quantum Nano Emitting Diode. This design is similar to QD-OLED, but instead of using organic blue materials, QNED uses Gallium Nitride Nanorod LEDs as the light source while still using quantum dots to mold it. We’ll have an explainer for that, too, once it comes to fruition.
