Liu Haiping

Since the rise of the concept of "full screen" two years ago, different brands of mobile phone manufacturers have shown their magical powers. First, Apple and Liu Haiping launched the iPhone X, which became numerous once it went public.

Water drop screen

Then, on the basis of Liu Haiping, a water drop screen evolved. For an instant, Liu Haiping's bristle was heard.

Digging screen

At the end of 2065438+2008, Samsung released the world's first hole-digging screen mobile phone, which directly promoted the overall screen to look better.

Although the digging screen is not perfect, it is still several generations ahead of Liu Haiping, which first claimed to be a "full screen"! The "small black spots" that major manufacturers have been trying to reduce but can't be completely removed are essentially front cameras.

Therefore, based on the realization of "off-screen fingerprint" technology, the industry began to put forward the idea of "off-screen camera".

This time, ZTE, one of the backbone brands of domestic products, leads the industry! ZTE's recently launched AXON 20 5G has become the world's first off-screen camera phone to achieve mass production, truly achieving a "full screen".

To tell the truth, emotionally, the landlord is very pleased to see a domestic manufacturer leading the revolutionary update of this screen. If the evolution from Liu Haiping to digging screen belongs to "quantitative change", ZTE's off-screen camera technology released this time belongs to "qualitative change".

Surprisingly, the first application of such "top technology" turned out to be a mid-range machine, not an annual flagship!

There is no doubt that this machine will be sold out soon.

Coincidentally, the mobile phone that the landlord's father used for three years almost needs to be replaced. The landlord bought one according to many years of snapping up experience-it can not only give his father a chance to express his mind, but also feel the real "full screen" of black technology for the first time!

Because the landlord can't wait to come up with the machine experience, the unpacking part is omitted here.

The front of the machine is temporarily confidential. Let's look at the back first. This ZTE Axon 20 5G mobile phone * * * has four colors, and the names are easy to recognize, namely "black hole gravity", "streamer sea salt", "phantom orange wind" and "Ziyue Lingyun". Since it is for dad, the color is naturally a relatively more stable "black hole gravity"

Only when I saw the owner of the real machine did I understand that the name "black hole gravity" was not casually named: the visual texture of the back cover of the machine was really amazing, showing a flowing posture in the light, with a strong sense of science and technology.

The logo of AXON 5G in the lower left corner is very conspicuous.

Today, when 5G technology is in full swing, it has almost become a mobile phone voucher.

The camera is located in the upper left corner, and there are four * * *, which are arranged vertically. From top to bottom: 8 megapixel wide-angle lens, 64 megapixel main camera, 2 megapixel depth-of-field lens and 2 megapixel macro lens. The flash is located next to the top wide-angle lens.

Below the lens group is ZTE's LOGO.

Look at the bottom of the machine, from left to right: card slot, Type-C port, call microphone, speaker.

When you take the card, you must look at the small hole before poking it. Don't poke it wrong, or it will easily damage the microphone-all mobile phones are the same.

Take out the card slot, you can see that the mobile phone supports dual cards, or single card +TF card to expand memory.

The buttons are all concentrated on the right, the top two are volume "+"and volume "-"respectively, and the diagonal texture below is the switch/wake-up button.

The key arrangement is more conventional, so the landlord will not expand it here.

In terms of weight, the bare metal is just 200g, which is basically consistent with the official calibration of 198g (the landlord inserted the card, and the measurement still has errors).

Judging from the bright screen effect of the front of the real machine, except for the slightly wider border at the chin, the other three sides can be called ultra-narrow. Look carefully at the navigation bar at the top of the machine, and the "little black dot" does disappear.

In terms of fuselage thickness, the landlord measured about 8mm with vernier caliper (don't be too tight to be afraid of scratching)

The machine comes with a charging head, which supports four different protocols: 5V/3A, 10V/3A, 12V/2.5A, 20V/ 1.5A * *.

In terms of parameters, the machine supports 30W fast charging, which also conforms to the latter three protocols.

Before talking about the experience, let's take a look at the configuration of this ZTE AXON 20 5G:

Qualcomm Snapdragon 765G runs a lot on the Internet, so the landlord will not do the test here. From the processor point of view, this is a machine that focuses on the mid-range market, aiming to let more people experience the real "light of technology".

As the world's first mass-produced off-screen camera phone, many friends must have bought/wanted to buy it. So what is the experience of the camera under the screen? Is the camera area completely unrecognizable to the naked eye?

We continue to look down.

The wallpaper used by the machine system by default is dark. In the dark, instead of staring, the position of the camera under the screen is almost completely unrecognizable.

However, at a special angle, we can still vaguely see a rectangular area in the middle of the top, which is lighter in color than the surrounding area, and the pixel particles seem to be larger-there is no doubt that below this position is the position of the camera at the bottom of the screen.

I'm curious to see the landlord here:

From a technical point of view, according to the official statement, in order to realize the off-screen camera, the machine has been rearranged and upgraded from five aspects: screen material, screen display chip/circuit, pixel and algorithm.

The landlord tried it, and the effect of active shooting is exactly the same as that of ordinary mobile phones, and even the beauty effect is softer and less exaggerated than most other brands.

However, in addition to solving the problem of active shooting, the off-screen camera also needs to solve the problem of screen display.

To this end, the landlord also tried the game experience of mobile phone for the first time.

Although the mobile phone has just been released, ZTE brand has cooperated with Tencent to optimize the special screen ratio (20.5:9) of this mobile phone. When the landlord plays the glory of the king, the game can be full-screen.

This special proportion of mobile phones has obvious advantages in playing games: the visual field on both sides is wider, which is equivalent to playing PC games with a fish screen, just like opening a physical hang-up. More importantly, as long as you don't stare at a point, in normal games, the position display of the camera at the bottom of the screen is basically the same as other positions, and there is no difference at all.

Compared with Liu Haiping's mobile phone in the landlord's own hand, although the game has also been optimized in full screen, in the area where the leftmost camera is located, a whole piece of "Liu Hai" completely blocks the picture, and the visual experience instantly drops by one grade.

The landlord made a simple comparison with Liu Haiping, digging screen and ZTE AXON 20 5G camera that he could find at hand. It can be seen that Liu Haiping's high-level separation is the most serious; The digging screen is slightly better, but the black camera has a strong sense of foreign objects; Only ZTE AXON 20 5G with an off-screen camera has a coherent top and extreme visual effects.

In addition to the off-screen camera, this ZTE AXON 20 5G puts all photosensitive elements, headphones and fingerprint identification modules at the bottom of the screen.

Off-screen light perception and on-screen vocalization articles are not easy to display. Here, the landlord will show you the demonstration of the use of off-screen fingerprints:

The fingerprint module is located near the chin of the mobile phone. From the appearance, the screen in this position is completely consistent with the surrounding area.

When using, if you lightly press near the module, a fingerprint symbol will be displayed on the screen, prompting the user to press the position; If you need to unlock it, just put your finger directly on it, and the phone will enter the main interface directly from the dormant state without waking up with a physical key, which is very convenient.

The function of taking pictures was not much for dad, but since the landlord had a child, the function of taking pictures of parents' mobile phones began to become important. After taking many photos, the children began to try to take pictures of scenery and food. So that the landlord needs to consider the shooting performance when choosing a mobile phone for them.

Here, the landlord will show several samples.

sunny day

The sunny picture is clean and neat, and the clarity and contrast are not bad.

cloudy day

Realistic in cloudy days, not much rendering in the later period, and the picture is close to the real scene.

microspur

At macro, the details are not bad, and the algorithm is fuzzy and natural. If you don't look carefully, it is even similar to optical blur.

The night scene is taken in the normal mode (there is a special night scene mode). For such a scene photo with great brightness contrast, the brightness control of the intersection is excellent, and there is no overexposure at all, which is beyond the landlord's expectation.

The overall performance of the camera is good, which is more than enough to meet the daily shooting needs.

Nowadays, looking at the mobile phone industry, large-capacity batteries and fast charging have already become the mainstream development direction. This ZTE AXON 20 5G also keeps up with the trend in this respect: the battery has a large capacity of 4220mAh, which supports mainstream Qualcomm Express.

The power reaches 30W when charging according to the protocol, and it can be charged 60% in 30 minutes.

The landlord tested it with the original charger+charging cable, and the charging power of the mobile phone can be stabilized at about 25W at low power (about 25%), which is close to the calibrated 30W( 10V/3A).

When the power is high, the third-party 65W fast charge and third-party wire (maximum support 100W) are used, and the charging power is stable at about 21W..

Although it is not working at full power, from the actual voltage and current value, combined with the output power of the charger shown above, it should also work in the 30W( 10V/3A) protocol.

Compared with other mobile phones on the market, although the fast charging technology of some products exceeds 30W in parameters, it is actually not compatible with the mainstream 65W fast charging on the market due to proprietary protocols, and only the original charger can realize fast charging, which is actually very unfriendly.

In terms of battery life, there are many influencing factors, such as WIFI mode, 5G mode and even screen refresh rate. But under normal circumstances, even in a state of high power consumption, it is completely no problem to insist on charging once a day.

On the network side, this ZTE AXON 20 5G supports dual WLAN and dual-channel acceleration.

Among them, the dual WLAN function is very practical in the following two scenarios in the understanding of the landlord:

① It can connect the router's 5G signal and ordinary 2.4G signal at the same time.

② You can connect two completely unrelated Wi-Fi.

In terms of signal, the landlord lives on the 22nd floor, and the call signal is not very good at ordinary times. During the call, if you walk in different rooms, you will often get no signal. The landlord used this ZTE AXON 20 5G for just a few days, but unexpectedly found that he did not encounter this situation. But it's not clear if it's accidental.

It is said that the emergence of 5G technology is of great significance and revolutionary technology, so does it really have such an artifact?

It happens that the residential area where the landlord is located is covered with 5G signals by the shopping mall next to it, and it is also very convenient to use and test. The landlord took the actual download as a test, and it can be seen that under the 5G network, the casual download speed reached 34 MB/s-far from the upper limit of 5G.

An APP like Meitu Xiu Xiu takes 3 seconds to download. The online legends are only "download started" and "download completed", which is somewhat exaggerated, but it is also true.

So what is the traditional download speed of 4G in the same location? Here the landlord also made a demonstration:

The landlord waited for a long time and found a peak speed, only 3.7MB/s, only 5 G110.

What is this concept? We might as well zoom in: others download a game with 5G for 3 minutes, while you need to spend 30 minutes under 4G network; Others have downloaded a game and played it, and your game is still being installed and decompressed …

The so-called "no contrast, no harm" probably means this.

First of all, as the world's first off-screen camera phone to achieve mass production, the biggest highlight of this ZTE AXON 20 5G is of course its super high face value and real "full screen" experience. In the absence of a separate camera, the most intuitive feeling that the full screen brings to the landlord is that the screen is extremely integrated and the sense of technology overflows the screen. For Liu Haiping and the hole-digging screen, at first glance, the advantages are very obvious.

Of course, one of the biggest technical problems facing the off-screen camera at present is whether the front camera can be used normally. In this regard, the landlord also showed it above. In addition to the off-screen camera, this ZTE AXON 20 5G also integrates an earpiece, a photosensitive element and a fingerprint module under the screen. Among them, the "screen sound technology" directly makes the handset originally located at the top of the mobile phone disappear directly, further enhancing the excellent experience of "full screen".

In addition, Qualcomm Snapdragon 765G processor blessing is more than enough for daily use; 64 million four shots, although not top-notch, are also top-notch among competing products at the same level; The blessing of 5G network directly makes it a "modern" mobile phone. Judging from the demand of the landlord's father for mobile phones, this ZTE AXON 20 5G has no problem for three years.

In the opening sentence, the landlord is very pleased to see that a domestic manufacturer has led the revolutionary update of this screen, and sincerely hopes that "rejuvenating the country through science and technology" will become the unchanging tone in the next few decades, and even become a basic national policy. At the same time, the landlord hopes that domestic manufacturers can release more "world first".
