The world’s first under-display selfie camera isn’t very good

ZTE’s Axon 20 5G is a better phone if you don’t care about selfies

In a perfect world, everything would fit under the surface of smartphone displays. That’s been the principle behind the past few years of phone design, at least, ever since the iPhone X escalated the bezel wars with its conspicuous notch. From in-display fingerprint sensors to pop-up selfie cameras, we’ve seen phone manufacturers take creative approaches to achieving the highest possible screen-to-body ratio.

The latest advancement in the bezel wars is the ZTE Axon 20 5G, which goes on sale today and is the world’s first phone to integrate its front-facing camera underneath the screen. While in-display fingerprint sensors are commonplace now, doing the same for selfie cameras has proven to be more difficult. Companies like Oppo and Xiaomi have been showing off demos for years, but ZTE has beaten them to the punch with the first commercial device.

In theory, the advantages are obvious. You get an unbroken display that doesn’t need to account for a notch or hole-punch, and you don’t have to build in a motorized mechanism for a pop-up camera module. Again, if the world were perfect, the camera would just magically exist under the display without compromising image quality on either end.

Readers, the world is not perfect.

Before we talk about the camera, we should talk about the display that lies on top. I doubt this has anything to do with the camera technology itself, but the fact is that the Axon 20 5G is one of the biggest smartphones I’ve ever seen. The 90Hz OLED panel is a massive 6.92 inches diagonal, which means its 1080p resolution is a little less sharp than you’ll find on other phones. It’s not a problem in regular use, though, and the screen generally looks pretty good beyond some rough off-angle color shifting.

What does not look good is the comparatively huge “chin” bezel at the bottom. Even though it would have been considered extraordinarily slim just a few years ago, it really stands out on the Axon 20 5G considering the supposedly breakthrough nature of the device. I’ve seen phones that have managed to integrate conventional selfie cameras into thinner bezels than this, which kind of undermines the point of putting one under the display.

That feeling only intensifies when you go through the Axon 20 5G’s setup process, which shows the camera in the worst possible conditions. The under-display integration is extremely noticeable on light backgrounds, like what you tend to see on settings screens. There’s a square patch of the screen that exhibits a clear dithering effect, making it appear much lower resolution than the rest of the panel. I will just say right now that I think it looks worse than a notch.

In more general use, it’s harder to notice. If you’re viewing photos or a full-color wallpaper, you can see the lower-resolution area if you look closely, but it isn’t quite as distracting. And as with other companies who’ve shipped Android phones with notches or hole-punches, ZTE’s default software uses a black background for the top part of the screen where status and notification icons are displayed, which does make the camera near-invisible. But really, if you need to resort to the same old notch-hiding techniques to disguise your under-display camera, what are we even doing here?

The above images show how visible the camera is on colorful, white, and black backgrounds.

Of course, the next obvious question is how the camera actually performs. The news here is not great either. I don’t want to diminish the technical achievement of getting a halfway functional camera under an OLED screen at all — it involves new types of transparent materials, pixel filters, and demosaicing algorithms to make sense of the light that hits the 32-megapixel sensor. But the result, unfortunately, is a bad selfie camera.

In good light, the Axon 20 5G’s selfie camera takes hazy, soft photos with weak colors and blown-out highlights. Compare it to the Pixel 5 below:

Pixel 5 (left) vs Axon 20 5G (right)

Just to be clear, that Axon 20 5G photo was taken with the portrait mode and smoothing filters turned off.

The disparity is just as stark in low light, with a ton of noise and obliterated detail. I turned off the Pixel 5’s night mode here to make it more of a fair fight, and it still crushed the Axon 20 5G.

This under-display selfie camera is merely functional, and that’s being generous. It can capture images through the screen, yes, which is indeed a minor miracle. But you probably wouldn’t want anyone else to see them.

This isn’t the most effusive compliment I can give a phone with a supposedly breakthrough selfie camera, but the ZTE Axon 20 5G is actually a much better proposition if you don’t care about selfies or video calls. It’s otherwise a pretty credible phone for $449, though despite providing a dollar price ZTE says it won’t be available in the US or Canada for now. (It’s €449 in the EU and £419 in the UK.)

While the Axon 20 5G has a huge footprint, it’s still slim at just under 8mm thick, and ZTE has included a reasonably large 4,220mAh battery inside. The processor is a Snapdragon 765G with an integrated 5G modem, same as the Pixel 5 and the LG Velvet, and it can be configured to have up to 8GB of RAM and 256GB of storage.

Other specs include an optical in-display fingerprint sensor that works fine, 30W fast charging over USB-C, and a headphone jack. There’s a 64-megapixel main camera and a 16-megapixel ultrawide, along with 2-megapixel macro and depth sensors that you can probably ignore. The main areas where ZTE has cut corners are its mediocre haptics system and an unimpressive downward-firing speaker.

The fact that ZTE finally got a phone like this onto the market is a notable milestone, but I’m not sure who the device is really for. The under-display selfie camera often looks worse and more distracting than a notch, and the image quality is clearly compromised. It’s ironic that a phone might be more appealing to an audience that actively doesn’t care about its key selling point, but that’s where we’re at with the Axon 20 5G.

Weekly poll: What features you look forward to in 2021?

At the start of this year we asked you what will be the most exciting features of 2020 smartphones. Now that the year is almost over it’s time to look back and see if makers delivered and to ponder what will be the highlight features of 2021 models.

The winning feature of the 2020 poll was under display selfie cameras. The first production phone with an UD camera is now a reality, but there’s just the one model and it’s just now becoming globally available (our review is coming up shortly, by the way).

The runner-up suggestion, cheaper foldable phones, also didn’t come to pass. Makers ironed out some of the kinks of the 2019 models, however prices remained out of reach for many.

At least the other options saw actual progress – 100+ megapixel cameras and periscopes have available for several models (including reasonably-priced ones), charging speeds (both wired and wireless) went through the roof, high refresh rate screens hit 144Hz in the premium market and 90Hz in the entry-level market.

If 2019 was the year of 5G, and 2020 was supposed to be the year of the UD camera, what will 2021 be about?

We’ll give the UD cameras and cheap foldables another shot as we’ve been hearing rumors that they may take another step forward next year. Here are some other suggestions about tech we can feasibly see next year that could prove to be the “next big thing”.

5x periscopes are quite common and there are a few 10x ones as well, but they all have a fixed focal length. Next year we may see periscopes capable of continuous zoom as O-Film and Oppo already announced modules with variable focal length. This will deliver a boost in image quality as digital zoom doesn’t work all that well with the small sensors and small apertures.

Smartphones broke the 100MP barrier this year and can go up to 600MP in the future – Samsung is reportedly working on such a sensor. Human eyes have resolution equivalent to around 500MP, so such a sensor will be unmatched in its ability to capture fine detail. If not 600MP, a 150MP 1” sensor would be a major upgrade over what we currently have as well.

Foldable phones – cheap or not – will get another round of improvements. But there are also rollable designs on the way. LG is supposed to unveil a rollable design as early as March and Oppo already impressed with a functioning prototype (though it said the tech isn’t ready for prime time). Samsung and Xiaomi (and probably others) are working on rollable designs as well.

Both foldable and rollable phones will benefit from a tougher protective material – ultra thin glass doesn’t cut it, we need something that can at least stand up to the regular scratches that happen in your pocked from keys and coins.

Corning Incorprated

Nvidia acquired ARM this year and while we’re unlikely to see Tegra chipsets power smartphones again (other companies may see this as anti-competitive), the GPU maker has designed custom ARM cores in the past. And, of course, GPUs – would a GeForce GPU make for better gaming phones than the current Mali designs?

Ultra Wideband (UWB) is already available on phones, but they mostly use it as a faster Bluetooth for sending data between devices. However, UWB has another skill – it can determine the relative distance and bearing of other devices. This is a great way to find your keys, but more advanced uses include pointing at something with your phone and hitting “On”, the phone will use UWB to figure out which of your smart home gadgets you were pointing out.

Admittedly, some of these features are more likely to happen next year than others. But even announcing a prototype can be valuable as the smartphone ecosystem is too large to adapt instantaneously. Just think how long it took for Android to get to grips with the changing screen size of a foldable phone when you open it.

Official OPPO A53 5G: how many news for the new entry level. Here they are all!

The Chinese giant OPPO presented in China its mid-range smartphone in its 5G version. There are many changes compared to his younger brother A 31 standard. Let’s find out which ones in the complete article

Oppo

Today , OPPO presented its new smartphone of medium-low range A 53 5G . The device represents the 5G version of the already known OPPO A 53, launched on the market last September. If you think that this new version only adds the 5G module to the standard one, you are wrong . The new OPPO A 53 5G brings important improvements in almost all sectors, from the hardware one but also considering the software one.

MediaTek Dimensity 720: the chip ready for 5G

The processor mounted becomes the MediaTek Dimensity 720 , capable of supporting the 5G module, to the detriment of the less performing Snapdragon 460 used on A 53. The display has a good 6.5 inch LCD panel with resolution Full HD + , one update frequency to 90 Hz and even a maximum brightness of 480 nit. The 5G version of A 53 comes with 4/6 GB of RAM and 128 GB of external storage memory, not expandable.

The multimedia compartment is still made up of a triple camera , but it gains in quality. The main now sees the presence of a sensor from 16 MP with focal aperture of f / 2.2 followed by a lens for macro shots and a depth sensor of 2 MP . The selfie cam instead results from 8 MP and it is inserted inside a hole in the upper left of the screen, as has been fashionable lately. The device measures 162, 2 x 75 x 7.9 mm and weighs 175 g , supports Dual-SIM and works with Android 10 customized with ColorOS 7.2 .

Autonomy is probably the only characteristic that does not improve compared to A 53 . The battery of the 5G version has a capacity of 4. 040 mAh against 5. 00 0 mAh of the standard version. Finally OPPO A 53 5G continues to place a 3.5mm jack as well as a fingerprint sensor on the side of the frame instead of on the back like its predecessor.

Prices and availability

The phone was unveiled in China today at a price of CNY 1. 299, about 160 euro at the exchange rate. It will probably also be distributed for the European market, even if at the moment there is no news about it for our country.
