Review of ZUK Z1 from Lenovo. ZUK Z1 Review

ZUK Mobile was founded in May of that year by the joint efforts of Lenovo and Qihoo 360. It is an independent brand that is developing in China and the international market. Its first product, the ZUK Z1 smartphone, was announced in August and is currently being sold through various channels in many countries around the world. The ZUK Z1 is not officially presented in Russia, and if you believe the Russian Lenovo office, it will not be supplied through “white” channels at all (upd: it will still be), but in the spring our compatriots will have the opportunity to purchase the latest ZUK models in official retail. However, there are no difficulties with online ordering ZUK Z1 from China (the special case of smartphones from JD being blocked at customs can be attributed to the activity of the Russian Lenovo office). You can order, for example, from. Update: ZUK Z1 officially goes on sale in Russia for 14,990 rubles!

Video review and unboxing

Design and equipment

The phone has the following equipment: the device itself, charging (2000 mA), a pin for opening the SIM tray, documentation and a USB Type-C 3.0 cable.

The gadget comes in two colors – white and dark grey. They differ not only in the color of the front and back, the shade of the metal frame, but also in the texture of the lid. The white version has a glossy lid, while the gray version is made of smooth plastic. In principle, both colors look cool, but I would prefer the gray one due to the more practical cover and the fact that the black edges around the screen are not as noticeable as in the case of the white Z1.

The design cannot be called original, but the fact that everything looks and feels good together is a definite plus. The company sensibly reasoned that users could tolerate an extra couple of millimeters of thickness in exchange for receiving a more capacious battery, so in a case with quite adequate dimensions of 155.7 x 77.3 x 8.9 mm, engineers included a battery with a capacity of 4100, which is not typical for a 5.5” screen. mAh Perhaps the ergonomics of the smartphone only benefited from the increased thickness - the Z1 lies cool and confident in the hand. The convenient shape of the case is also emphasized on the official website of ZUK - the company did a great job on it.

Above the display there are light and proximity sensors, a speaker, an 8-megapixel camera, and an LED indicator. Below it are two touch keys that flash with dots when touched, as well as a mechanical home button with a fingerprint scanner. The button has a touch layer used in the Chinese firmware ZUK ZUI (recognizes touches without pressing, as well as swipes), but I did not find any use for it in the Cyanogen firmware. The fingerprint scanner works quickly and accurately. If you prefer to keep your phone locked up, you'll be pleased with the sensor.

On the left is a tray for two nano-SIMs, on the right is a volume rocker and a power key. At the bottom is a microphone, a USB Type-C 3.0 port, and a loud, clear speaker. At the top end you can find an audio jack. The back of the Z1 looks simple, but tasteful - there is only the company logo, a 13-megapixel camera peephole in a metal ring, an additional microphone and a dual LED flash. The cover is not intended to be removed by the user, but you will be able to remove it if necessary.

The 5.5" display boasts Full HD resolution, providing a good pixel density of 401 ppi. The panel used in my sample is characterized by a bias towards warm shades, which, however, can be easily corrected in the screen settings in the LiveDisplay section. Viewing angles are high, brightness and contrast are not satisfactory. In general, the ZUK Z1 has a high-quality screen and we must thank the developers for the fact that their practical approach to the model resulted in a rejection of the fashionable, but mostly useless 2K resolution in 2015.

Software

Chinese versions of ZUK Z1 have ZUI firmware, while international ones come with Cyanogen OS 12.1 based on Android 5.1.1 Lollipop. If you buy a model from the Middle Kingdom, then it can come with any firmware depending on the desire of the seller - he can leave everything as is, or he can spend a little time and flash the device to cyan for you. In any case, converting the Z1 from ZUI to Cyanogen is not a very difficult process (though I couldn’t do it on Windows 10, so I had to look for a computer with Windows 7). There will be an update to Android 6.0 Marshmallow. ZUK has already announced that the Z1 will be the first Chinese smartphone with Android 6.0 on board.

You are probably familiar with the Cyanogen OS 12.1 firmware. In a nutshell, it's stock Android on steroids. It is as simple and airy as the robot from Google itself in the Nexus, but it offers many times more features and functions, and useful ones at that. Unfortunately, the latest update broke the font on the standard theme, so I had to switch to an alternative one. I didn't notice any other glitches.

The set of preinstalled programs is minimal. Limited primarily to recommended Google apps and services. Although there is something from Cyanogen: a branded gallery, a screencast (recording video from the screen), themes, a file manager, a browser, an advanced equalizer for adjusting the AudioFX sound. Without it, the phone with Denon D600 headphones does not sound very expressive, flat and without sparkle - additional bass will not be superfluous. In general, the sound of the Z1 corresponds to a smartphone with an integrated Qualcomm codec.

Camera

The main camera module includes a 13-megapixel Sony IMX214 sensor, f/2.2 aperture, autofocus, dual LED flash, and optical image stabilization. If you shoot in good lighting, then the photos will please you with details and clarity, but if you decide to shoot in room light or go outside in the evening, then be prepared for noise. However, the optostab does its job and helps to get good pictures in almost all scenarios, and the color rendition (saturation, contrast, white balance) does not disappoint. But sometimes underexposure that occurs in automatic mode requires special attention from the user. Take a look at the photos:

I was pleased with the 8-megapixel camera with the OmniVision OV8865 sensor. Selfies on it turn out worthy both at home and on the street.

The maximum video resolution is limited to 1080p. There are slow and fast shooting modes (60 frames per second). Optical stabilization works well when recording a video with the rear camera, if you hold the phone with two hands, but in the case of recording with the front camera with one hand, shaking cannot be avoided. Tracking autofocus is activated in the settings; it cannot boast of accuracy and speed. The sound is recorded well, the voice is clearly audible, but the microphones do not cope well with road noise. Overall, the video sequence can be rated "good".

Benchmarks and Performance

If you are still wondering why ZUK decided to use the Qualcomm Snapdragon 801 processor (version MSM8974AC) for the current 2015 model, then I recommend reading a comparison of OnePlus One on Snapdragon 801 and OnePlus 2 on Snapdragon 810. In short, the Snapdragon 801 chipset handles games just as well and is more stable. “The Snapdragon 801 is powerful and reliable,” the official ZUK website tells us. And it is true. The Adreno 330 chip is responsible for the graphics, 3 GB of RAM, 64 GB of permanent memory. There is no expansion slot in the Z1, but the specified capacity should be enough for most users. At worst, there is support for external drives via OTG, and cloud services have not been canceled (they helped me out once when I needed to transfer screenshots and photos from the camera to a computer, but the Type-C cable was left in the office).

Benchmark scores: AnTuTu 6.0 – 55,746, Geekbench 3 – 994/3039, GFXBench – 11/27 fps, 3DMark Ice Storm Unlimited – 19,649, 3DMark Sling Shot 3.0 – 1226, Epic Citadel Ultra – 55.5 fps. In general, parrot lovers will be pleased. But not only them - the players will also be delighted. After all, the device can easily handle powerful 3D games like Unkilled, Asphalt 8, World of Tanks. With simpler games, accordingly, everything is also tip-top. And with an impressive amount of internal storage and a high-quality 5.5” IPS screen, the Z1 turns into a real gaming smartphone.

discharge when playing video

And thanks to the 4100 mAh battery, you can play games for a long time. So in the game Asphalt 8, in an hour with a comfortable brightness, the ZUK Z1 dropped by only 12% (that is, you can count on 8 hours of play). And in video player mode, the smartphone lasted 8.5 hours with maximum screen brightness. In everyday life, you can expect 3-5 days of work with 5-10 hours of screen time. And, please note, this is a phone that is not positioned as a long-liver, and not a model with an AMOLED screen. Before us is a well-built smartphone, the developers of which did not chase fashion trends, not giving a damn about the tendency to reduce thickness, the capricious Snapdragon 810 chipset and the QHD resolution, which is simply not necessary for a high-quality IPS matrix with a diagonal of 5.5 “.

conclusions

ZUK Z1 is the first pancake, but prepared according to a proven recipe, where the ingredients are selected in such a way as to please a wide range of consumers. We can say that the device is devoid of obvious weak points, and if you do find them, then I’m sure that the energy consumption and performance will more than compensate for them. This is a truly solid, balanced smartphone, the strengths of which will not be easy to replicate in the second generation.

Perhaps the only thing that can prevent the boom in demand for ZUK Z1 among Russians is the dollar exchange rate. The average price of a model from China is $300, which at 77 rubles for 1 dollar translates into 23 thousand rubles. For this money, you can consider a lot of things in official Russian retail (for example, Samsung Galaxy S5, ASUS Zenfone 2, OnePlus One 64 GB) and there is plenty to choose from in Chinese online stores (for example, Meizu MX5 or Xiaomi Redmi Note 3 with a mountain of branded Xiaomi accessories for return). I wonder what prices ZUK will officially come to us with and what the new models will offer? There's not long to wait.

Much has already been said about the ZUK Z1; the model is known primarily as an excellent offer in various Chinese online stores such as Aliexpress, Gearbest, etc. The scandal with JD.ru added fuel to the fire, which invested a lot of effort in advertising and promotion, but in fact, buyers were never able to receive their devices, since customs simply unwrapped the parcels with them. Apparently, the serious interest of users in the ZUK Z1 prompted the Russian office of Lenovo to officially sell it. It’s nice that the price was even lower than in Chinese stores.

You know, to please a person even at the level of unpacking a smartphone, very little is required: that the box is more or less beautiful, that everything inside is neatly packed, or that the kit contains at least something different from the traditional set. Lenovo included a flat USB Type-C cable and this made me and, perhaps, potential buyers very happy.



Appearance, materials, control elements, assembly

From the front, the ZUK Z1 resembles hundreds of other faceless smartphones with rounded edges and a button below the screen. When you turn the device sideways, you see a direct resemblance to the iPhone 6, especially in the lower part with the main speaker mesh. I sincerely don’t understand why the designers liked this move from Apple so much that they began to copy it en masse, but the fact remains a fact. The ends of the ZUK Z1 are very similar to those of the iPhone 6, however, with one non-obvious difference: the ZUK Z1 does not slip in your hands like the iPhone 6, which makes its design much more practical.






Below are photographs of the device with a description of the arrangement of the elements and my short comment on their convenience.



Area above the screen: indicator light, light and proximity sensors, front camera



Area below the screen: fingerprint scanner and touch buttons


Right side: volume rocker and power button



Left side: tray for two nanoSIM SIM cards


Top: 3.5mm headphone jack


Bottom: main speaker, microphone, USB Type-C port

The smartphone has a convenient and clearly visible light indicator; you can easily see when you have received a new notification. The fingerprint scanner works at lightning speed; you don’t even have time to touch it, and the device is already unlocked. By the way, despite the fact that the scanner is recessed into the body, it is also a button. In the settings there is a choice between using touch (located on the sides of the scanner) or on-screen buttons; I preferred the second option.

The volume rocker and power button fit exactly under the thumb, the keys themselves have a short stroke with a characteristic click, and are very convenient to use.

The volume of the main speaker is quite high, but at the maximum value it begins to wheeze, so the device is unlikely to be suitable as a music speaker.

The back cover, unlike the ends, is made of matte smooth plastic, which from the outside looks very much like metal.


There are no complaints about the assembly of the model, the device is well assembled, all parts are tightly fitted to each other, there is not the slightest hint of creaks or play.

Dimensions

Of course, the ZUK Z1 is far from a record holder in terms of dimensions, given that it has a diagonal of 5.5 inches, and in the same Note 5 - 5.7, but it is as comfortable to hold in your hand as this phrase is, in principle, true for phablets. In most cases, you will need both hands to use the device.





Compared to Apple iPhone 6

Screen

My impressions of the display are mixed. On the one hand, it has good resolution, an oleophobic coating, a good brightness range and more or less natural color rendition. On the other hand, the screen turns a little yellow, this is especially noticeable if you place the device next to the same iPhone 6. Therefore, before purchasing, I strongly recommend looking at the ZUK Z1 display in person.

I didn’t like the work of the light sensor, the brightness values ​​are greatly underestimated, and I constantly have to adjust it manually.

operating system

The device runs Android 5.1 and CyanogenOS. As one of our readers correctly corrected me, the difference between CyanogenMod and CyanogenOS is that the latter is much more stable and already optimized for everyday use, while Mod is still more like a beta version.

To be honest, I haven’t used Cyanogen smartphones for a long time. Many of the functions that exist on Cyan were new to me, so I apologize in advance if I say any obvious things.

Firstly, I really liked the operation of the telephone part of the smartphone. The dialer contains Russian letters; moreover, the system can identify outgoing unknown numbers independently and show reviews on them from users. This helps a lot when you get a call from another beauty salon or survey service.

Another cool feature is fine-tuning profiles: you can fine-tune the behavior of your smartphone under different conditions. For example, for me the key parameter was the network switching to 2G Only mode as soon as the device connected to the home Wi-Fi network. I was surprised to discover that even such a niche scenario is possible on CyanogenOS. And such little things add up to a whole detailed article, which we will definitely prepare.

You know, now it’s hard to call me a fan of custom firmware and other “customization”, at some point you simply stop paying attention to such functions, but after using CyanogenOS on the ZUK Z1 you begin to remember why millions of geeks update their smartphones immediately after purchases . Such deep customization and detailed elaboration of each item cannot but captivate. And here all this is right out of the box without the need to fuss with “root”, “recovery” and flashing the firmware.

Performance

On the one hand, the smartphone does not have the latest Qualcomm Snapdragon 801, and on the other hand, we have an old, proven chipset that has proven itself in some models. Plus, let's not forget that the performance of modern processors is excessive, so even the previous or the generation before that is enough for everyday use and productive toys. This is confirmed by the ZUK Z1.



During everyday use, the device almost does not heat up; only traditional benchmarks (Antutu, 3DMark) managed to make it “hot”. I would like to note the lack of a slot for a memory card as a disadvantage, but only 64 GB of internal memory is enough for most users, even with a reserve.

Autonomous operation

I was very pleased with the operating time of the device, especially for everyday use. After almost 3 hours of screen activity plus enabled synchronization and data transfer via mobile networks, the ZUK Z1 was discharged by only 36%! The model’s behavior “in sleep” is also excellent; the discharge per night was no more than 2%. The device also supports Qualcomm Quick Charge 2.0 technology, but due to its large capacity it still does not charge very quickly. In 30 minutes it is 25%, and in an hour it is 50%; a full charge requires 2 hours 15 minutes.

Camera


The main camera is average in all respects. While during the day you can still take more or less good pictures, in the late afternoon or under artificial lighting noise appears and detail deteriorates. The video is recorded in 1080p, the recording quality is average, there is pressure focusing and stereo sound.

The ZUK brand is a subsidiary of Lenovo: just look at the box, where the inscription “a Lenovo company” is eloquently displayed. Chinese manufacturers' low-cost subsidiary brands have been appearing quite often lately. For example, Fly acquired the Wileyfox brand, Huawei has Honor, and ZTE has Nubia. Lenovo joins this company with its ZUK.

True, there was a little confusion with the sale of devices of this brand on the territory of the Russian Federation. How reported Gleb Mishin - vice president and general director of Lenovo in Russia, the CIS countries and Eastern Europe - on his Facebook page, at the moment Lenovo has not certified a single ZUK model in the Russian Federation. The official start of sales of devices in Russia is scheduled for spring of this year. So far, ZUK smartphones are coming to us through various online stores, which Lenovo, judging by Mishin’s post, is not too happy about.

What does it mean? Let’s explain it in simple terms: now purchasing a ZUK smartphone is comparable to purchasing some unnamed device. In the event of a defect or breakdown, claims can only be made to the store where the purchase was made.

On paper, the ZUK Z1 looks like a very interesting offer: for 23 thousand rubles the user gets a lot of things.

⇡ Appearance, ergonomics, fingerprint scanner

Mid-price smartphones are often very similar in appearance to each other. The main thing in them is not the image, but the maximum number of options for little money. ZUK Z1 is a typical representative of this family: outwardly it is completely unremarkable. One can only complain about some similarities with the iPhone, but we are already so accustomed to this that we did not even immediately pay attention to it.

ZUK Z1 turned out to be quite large. The side frames around the large screen are of standard width - about three millimeters on each side. The screen occupies only 69% of the front panel area - there is quite a lot of unused space on the front, which increases the size of the gadget. Using the Z1 with one hand is possible, but you will have to try, it is a really large gadget. It weighs 175 grams. The thickness of the case is quite standard - 8.9 millimeters.

At the top of the front panel there is a front camera lens and a speaker grille. At the bottom is a rectangular Home key. On either side of it are touch-sensitive, but quite physical, “Back” and “Menu of open applications” keys.

A fingerprint sensor is integrated into the Home button, which can be used to unlock the device. It works quite correctly: the device quickly wakes up after pressing the center key with a finger “familiar” to the device, the percentage of errors is minimal. To add a new fingerprint, you need to touch the sensor about twenty times; up to five fingerprints are stored in memory.

When a hieromonk sings better than most lay people, he becomes even more popular than boring, sugary pop stars. When a smartphone is created with obvious hints “we are not basement-dwelling poor people - we are Lenovo’s special forces!” - the demand for it becomes greater.

Let's just not get hung up on the image component - today you can't boast to your friends, saying, “I bought myself a Zuk!”, but more recently, Lenovo laptops, for example, evoked the same sympathetic smiles. It will endure and fall in love, as was the case with other brands.

And in general, everything that is good about this smartphone has nothing to do with Lenovo. Its own high-quality display, a rare thoroughbred Qualcomm processor instead of the consumer-grade MediaTek, really great battery life (without a battery-hogging Intel processor or overheated Helio X10), and a reasonable price, by the way. Because Lenovo and Huawei have long been dizzy with their coolness, and along with it their price tags have lost their adequacy.

You will laugh, but the main disadvantages of the smartphone also stem from the fact that it is not directly related to Lenovo. That's where the Chinese engineers were when the ZUK developers implemented the Cyanogen OS firmware, which does not work optimally with photo and video shooting? Why in the international version of the smartphone the Cyrillic font is stretched wide by default - was it really impossible to verify the normal localization of the only default smartphone after many years of supplying mobile phones to Russia?

The guys from ZUK will rightly be indignant and say that all the achievements and shortcomings of the new model lie solely on their conscience. And with the approach “we have a powerful inexpensive mobile phone - and the grass won’t grow, fix its glitches yourself,” an army of manufacturers has multiplied in the Chinese and Russian markets, which even we, reviewers, are not able to remember.

Once again, for clarity, in the triangle “display quality / power / endurance”, the smartphone is surprisingly good and can only compete with the above-mentioned Redmi Note 3. But the firmware needs to be “polished”, and the ugly behavior of the rear camera needs to be corrected at least to the level
