The device is not detected by the computer when connected using a USB cable. The device is not detected by the computer when connected using a USB cable computer does not see ZUK Z1 what to do


For the first time, Lenovo ZUK Z1 was announced in 2015 in August, it was not much time from that moment, therefore this model remains relevant. Now briefly about the main thing. Lenovo ZUK Z1 is equipped with a large 5.5-inch IPS screen, built on a sufficiently powerful, but no longer fresh processor, endowed with a battery, finger print scanner and a USB port of Type-C 3.0. And more detailed about all the characteristics and capabilities of Lenovo ZUK Z1 can be found in the review below.

Design
The appearance of any device is its business card and, in the case of Lenovo ZUK Z1, individuality is clearly traced. The smartphone is really not like Lenovo, but has its own features and very interesting. Metal bezel passes around the perimeter, securely fastening the entire design. On the front panel, the side frames are quite thin, but the indentation from above and from the bottom from the screen is quite large, which creates a feeling of some volume. Also, heavyness adds a considerable 8.9 mm corps profile, which is a lot of current standards. The back side of the lid spoils the entire appearance, as it has a glossy plastic surface and easily collects all fingerprints, creating an uncertainty. But this property is only at the White Model, there is only two color solutions in general - white and silver color. The latter has a matte surface of the rear part, which is much more practical and prettier, in my opinion. dimensions: 155.7 x 77.3 x 8.9 mm, weight - 175 grams.
Screen characteristics
Lenovo ZUK Z1 has a screen of 5.5 inches with physical dimensions of 68 x 121 mm, made using IPS technology matrix with maximum resolution - 1920 x 1080 pixels, the density of pixels at the same time amounted to 401 ppi. GOILLA Glass glass covers the screen and reliably protects against damage. Multitach supports up to five simultaneous touch, there is also a sensor for automatic adjustment of the brightness of the screen and anti-reflective coating.
The image on the screen has pleased with its good brightness margin, which allows you to remain readable on a sunny day. The viewing angles are most optimal. Colors are sufficient enough, you can even say somewhat oversaturated, which is a minus, the color coverage is great enough. The contrast level is also large 1270: 1, the maximum brightness is 480 kD / m2. In general, the screen is not bad, but requires manual setting Color gamma.


Hardware features
The basis of this model of the smartphone has entered Qualcomm Snapdragon 801. This is a good processor and having enough power, but at one time, because this moment Such a processor is obsolete. The processor quad-core with the architecture of MSM8974As, and the maximum clock frequency is 2.5 GHz. The Adreno 330 graphics adapter is used, the maximum frequency of which is 578 MHz. The volume of operational memory in this case is 3 GB. Built-in flash memory - 64 GB, but in fact the user is available slightly less - 53 GB. You can not supplement using memory cards, but you can connect additional drives.
Performance from Lenovo ZUK Z1 at a decent level to compete with other models, and although not the most recent processor is used, but the flagship platform makes its business. The smartphone works simply, quite quickly, showed itself perfectly in multisazing conditions, smoothly demonstrates video, and also launches any resource-intensive applications and three-dimensional games.
Sound
I would like to say a few words about sound, by which the manufacturer endowed Lenovo ZUK Z1, because the sound here is also very worthy. Usually we do not pay due attention to the sound, because rarely, which manufacturer is bothering therefore, there is a slightly loud sound somewhere, and somewhere a little more quiet. And although in this model you will not find an audio player and FM radio, you can use the standard version of the program Google Play. Music. Hearing dynamics and external speakers are excellent, there are no complaints about this.


Camera
It was so that we all stopped using cameras, with the exception of professional, photographing everything exclusively on phones and tablets, so when buying a new model, we always pay attention to the quality of the camera. Lenovo ZUK Z1 is endowed with two modules of digital cameras, front with 8 MP and the main on 13 megapixel. The main chamber has a sensor from Sony IMX214 EXMOR RS, F / 2.2, a five-component lens, and by itself the LED flash and autofocus. The front-line endowed with a sensor from Omnivision OV8868, F / 2.2. The quality of the cameras pleased, settings are many, they can be mastered as needed, but the photos and video are obtained very worthy.
Communications
The phone supports 2G GSM and 3G WCDMA communication standards, but also LTE in the three most common ranges. Wi-Fi Direct, Bluetooth, GPS, as well as USB 3.0 Type C connector, is also supported. Everything works without complaints. The device supports the operation of two SIM cards, which is convenient and practical.
Output
Lenovo ZUK Z1 is a really decent model organized on the flagship platform, which is endowed with a mass of opportunities, although there are some shortcomings in the form of oversaturated colors of the screen, and otherwise everything is very good.

Flagship of the new suburban company Lenovo

The world-famous manufacturer of electronic equipment The Chinese company Lenovo announced this year about the creation of a separate subsidiary, which is called ZUK and which will produce products to the market under the relevant brand. It seems that large Chinese producers are in lately It was in fashion: similar actions before this was taken by ZTE with its sub-near Nubia, as well as Huawei, which highlighted the Honor division into a separate trademark.

The firstborn in the new ZUK family became flagship smartphone Z1 with characteristics corresponding to products if not top-end, then the level is explicitly above average. The device cannot boast except that the most fresh SOC, but in all the rest of the Z1 turned out to be no worse than other modern flagships. In the middle of August, the start of sales ZUK Z1 was given in China itself, and later, in September, it was announced soon the release of the international version of this model intended for the European market.

Contents of delivery

For sale, the ZUK Z1 smartphone enters the attractive type of packaging made in the form of a flat square box with a folding lid. Inside all accessories are decomposed on separate smaller cardboard boxes. The packaging is concisely decorated and stylish, it is a restrained combination of white matte textured cardboard and silver inscriptions, it is advantageous from a familiar habitual alphabetry, often found in the products of Lenovo itself.

Complete set is minimal: only a charger with output 2 A and a pretty rubberized shouting cable USB 3.0 Type C is found in the box. The key to extract SIM cards is attached to a cardboard box with paper documentation.

Appearance and ease of use

ZUK Z1 design is peculiar. The smartphone is absolutely not similar to any of the smartphones known to us itself, the analogy here can be more likely to spend with the products of the same LETV or, for example, with the firstborn Huawei Mate, released a few years ago. In comparison with LETV ONE, the hero of the review generally looks like a twin: smartphones and externally like two drops of water, and the structure has the same up to the presence of a port USB Type C, except, of course, the presence of a fingerprint scanner on the front panel at ZUK Z1.

Not to say that ZUK Z1 is very beautiful, but also uninteresting it too. It simply arises a difficult feeling that this product is more designed for Asian taste than on the Europeans. Nevertheless, the smartphone is quite present.

In addition, the device turned out also enough heavy and large: a considerable thickness of the case, a wide frame around the screen and an excessive mass cannot be noticed. Not for each hand such a massive apparatus will seem comfortable, lovers of small neat mobile devices Through the ZUK Z1 itself that there is no "shovel".

The monolithic ZUK Z1 case is unsolved, so the cards here are installed in the side connector and removed using a complete metal key. The connector is only one, it takes dual metal sleds that you can lay two Nano-SIM format cards - there was no place for a memory card in a smartphone.

The front panel ZUK Z1 is completely covered with flat protective glass Gorilla Glass, not having lands or sidelights. Under the glass is hidden full set Familiar elements: sensors, front chamber eyes, led indicator Events - everything is in place.

At the bottom, under the screen there is a large rectangular mechanical control key with the fingerprint scanner built into it, on the sides of which two round points of the additional buttons are highlighted. Since the buttons are not equipped with specific icons, their assignment can be changed in the settings menu, which is convenient. In the same menu, by the way, you can additionally enable the display on the panel screen with the same buttons, only virtual, their purpose and order can also be changed. The functionality of the hardware buttons is expanded: they react both on solitary and double, as well as for a long press, and all these functions can be manually reassigned in the menu.

It is curious that the universal software, calculated immediately into several different models, is curiously. To begin with, the user itself is proposed to determine where the print scanner is located on the case: in front, behind or somewhere else. With the help of the sensor center button, you can not only identify the fingerprint user (Touch ID), but also to perform additional operations, such as switching between running applications, return to the previous menu and others. The scanner itself works clearly, the finger to it can be brought under In any angle, if you touch exactly, then there will be almost no errors in recognition.

On the back of the camera, the camera module does not repel out of the housing, the glass is protected by a metal ring, into which it is slightly drowning, so that there is no reason to fear the appearance of scratches. A dual flash is seen next to two LEDs of the same color. In order to apply the flash as a flashlight, you need to proceed in the menu quick access In the curtain of notifications.

The speaker here is derived to the lower end end of the case, and its grille is standardly made in the form of several large round holes - the Chinese love to copy the design of Apple products. On the other side of the USB 3.0 Type C connector, a microphone hole is located. The connector itself supports the connection external devices In OTG mode, it will be necessary to prepare the OTG adapter of a new type separately.

On the opposite, the upper end is an audio output with a diameter of 3.5 mm for headphones. Mounts for the strap on the housing is not, plugs on the connectors - too: the smartphone is not secured by protection against water and dust.

As for the colors of ZUK Z1, there are only two of them, while the housing, depending on the color, have a different coating. White option, as we have in the photos, the surface of the back cover is glossy and brand, while the silver Z1 coating is made under the species of metallic, and besides, it is matte and non-smoke, which is more practical.

Screen

Smartphone ZUK Z1 is equipped with touch screen IPS, combined with protective glass Gorilla Glass. The physical dimensions of the display are 68 × 121 mm, a diagonal is 5.5 inches. Screen resolution is 1920 × 1080, the density of the points is 401 ppi. The frame around the screen is not completely narrow: about 4.5 mm on sides, 15 mm from above and 19 mm below.

The display brightness has automatic adjustment based on the lighting sensor. There is also an approximation sensor that blocks the screen when making a smartphone to the ear. Multitouch technology allows you to handle 5 simultaneous touches. The screen can be activated by double tapping on the glass.

Detailed examination using measuring instruments He conducted the editor of the "Monitors" and "Projectors and TV" sections, Alexey Kudryavtsev. We present his expert opinion on the screen of the sample under study.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface resistant to the appearance of scratches. Judging by the reflection of objects, the anti-glare properties of the screen is not worse than the Google Nexus 7 (2013) screen (hereinafter simply Nexus 7). For clarity, we give a photo on which the white surface is reflected in the screens (left - Nexus 7, to the right - ZUK Z1, then they can be distinguished by size):

ZUK Z1 screen is slightly darker (brightness of photographs 113 versus 115 at Nexus 7). Two of the reflected objects in the ZUK Z1 screen is very weak, it suggests that there is no airbap between the external glass and the surface of the LCD matrix) (OGS-One Glass Solution type screen). Due to the smaller number of boundaries (type of glass / air) with highly different refractive ratios, such screens look better in the conditions of external illumination, but their repairs in the event of a cracked exterior glass costs much more expensive, as it is necessary to change the entire screen. On the outer surface of the screen there is a special oleophobic (fat-repellent) coating (very effective, noticeably better than Nexus 7), so traces from fingers are removed significantly, and appear at a lower rate than in the case of conventional glass.

With manual control of brightness and when displaying the white field full screen The maximum brightness value was about 480 cd / m², minimum - 5.3 kD / m². The maximum brightness is high, and considering excellent anti-reflective properties, readability even on a sunny day outdoors should be at an acceptable level. In complete dark, brightness can be reduced to a comfortable value. In presence automatic adjustment Brightness on the light sensor (it is the left side of the front loudspeaker in one dark strip with it). In automatic mode, when changing external light conditions, the screen brightness is rising, and decreases. The operation of this function depends on the position of the brightness adjustment slider. If it is 100%, then in complete darkness, the auturance function reduces the brightness of up to 75 kD / m² (multipato), in conditions of an artificial light of an office (about 400 LCs) sets 310 cd / m² (it was possible and smaller), in very bright surrounded (corresponds to the coverage of a clear day outside the room, but without direct sunlight - 20,000 LCs or a little more) The brightness rises to 480 cd / m² (to the maximum - it is necessary); If the adjustment is about 50%, the values \u200b\u200bare as follows: 4.3, 120 and 480 kD / m² (the first value is low, the remaining two are suitable); The regulator is 0% - 4.3, 8.8 and 480 kD / m² (already the first two values \u200b\u200bare understated, which is logical). It turns out that the luminous lifting function works more or less adequately and allows the user to customize its work under individual requirements. At any level of brightness, the backlight modulation is practically absent, so there is no screen flicker.

IN this smartphone Used IPS type matrix. On micrographs, if desired, you can consider the structure of subpixels typical of IPS:

For comparison, you can familiarize yourself with the micrographic gallery of the screens used in mobile technology.

The screen has good viewing angles without a significant shift of colors, even with large looks from the perpendicular to the screen and without inverting shades. For comparison, we give the photos on which the same images are displayed on the ZUK Z1 and Nexus 7 screens, while the brightness of the screens is initially installed by about 200 kD / m² (on a white field in full screen), and the color balance on the camera is forcibly switched to 6500 K. Perpendicular to screens White field:

The uniformity of the brightness and color tone of the white field is good. And test picture:

The colors on the ZUK Z1 screen are oversaturated (pay attention to tomatoes), and the color balance is noticeably different from Nexus 7. Now at an angle of about 45 degrees to the plane and to the side of the screen:

It can be seen that the colors did not change much from both screens, but the contrast in ZUK Z1 decreased to a greater extent due to the larger decreement of black and reduce the brightness of the image. And white field:

The brightness at an angle of the screens has decreased (at least 5 times, based on the difference in exposure), but in the case of ZUK Z1, the decline of brightness is greater. The black field when the diagonal is deviated to the diagonal, heavily and acquires a yellowish or slightly purple shade. Photos below are shown (the brightness of white areas in the perpendicular plane of the directions of the direction is approximately the same!):

And at a different angle:

With a perpendicular view, the uniformity of the black field is imperfect, in addition, the white body skips light from the backlight LED:

Contrast (approximately in the center of the screen) high - about 1270: 1. Response time when switching black-white-black is 25 ms (13 ms incl. + 12 ms Off.). The transition between halftons of gray 25% and 75% (according to the numerical color value) and back in total it takes 43 ms. Constructed by 32 points with an equal interval in the numerical value of the shade of a gray gamma curve did not reveal in neither lights or in the shadows. The indicator of the approximating power function is 2.64, which is noticeably larger than the standard value of 2.2. At the same time, the real gamma curving in places is strongly deviated from the power dependence:

Due to the dynamic and very aggressive adjustment of the brightness of the backlight in accordance with the nature of the displayed image (the brightness of the brightness decreases) the resulting brightness dependence on the shade (gamma curve) does not correspond to the gamma curve of the static image, since the measurements were carried out with a consistent output of shades of gray almost in full screen. For this reason, a number of tests are the definition of contrast and response time, comparing the illumination of black at angles - we were performed when withdrawing special templates with constant medium brightness, and not one-photo fields in full screen. We give the dependence of the brightness (vertical axis) from time when switching from a black field to white in half the screen alternately, the average brightness does not change and the dynamic adjustment of the illumination brightness does not work (graph 50%/50% ). And the same dependence, but with the alternate output of the fields in full screen (schedule 100% ), while the average brightness is already changing and the dynamic adjustment of the brightness of the backlight works in might and

In general, such an unleated brightness correction, nothing but harm does not bring, as it reduces the distinguishability of gradations in the shadows in the case of dark images. In addition, this dynamic adjustment in the output of any image other than the white field in full screen, significantly underestimates the brightness, which worsens readability on bright light.

Color coverage is wider than SRGB:

We look at the spectra:

They are atypical, but we have already seen them in the case of Sony Xperia Z2 and several other devices. Sony points out that these screens use LEDs with a blue emitter and green and red phosphor (usually a blue emitter and yellow phosphor), which in combination with special matrix light filters and allows you to get a wide color coverage. Most likely, this statement is true for ZUK Z1. For a consumer device, a wide color coverage is in no advantage, but a significant disadvantage, since as a result of the colors of images - drawings, photos and films, - srgb-oriented space (and such an overwhelming majority), have unnatural saturation. This is especially noticeable on recognizable shades, for example on skin shades. The result is shown in the photo above.

The balance of shades on the gray medium scale, as the color temperature is significantly higher than the standard 6500 K, and the deviation from the spectrum of absolutely black body (ΔE) is much more than 10, which even for the consumer device is considered a bad indicator. However, the color temperature and Δe change little from the shade to the shade - this has a positive effect on the visual assessment of the color balance. (The darkest areas of the gray scale can not be considered, since there the balance of colors does not matter, and the measurement error of the color characteristics on the low brightness is large.)

This device has the ability to adjust the color balance with the help of one of three profiles.

On schedules above curves Standard comply with the results without any correction of the color balance, and curves Warm. - data obtained after selecting the profile of the same name (at the same time the maximum brightness of the white field decreased to 460 cd / m²). It can be seen that the change in the balance corresponds to the expected result, since the color temperature approached the standard value, and even Δe has decreased slightly, but, unfortunately, it still remained above the critical value of 10 units.

Let's summarize. The screen has a high maximum brightness and has excellent anti-glare properties, so the device without problems can be used outdoors even summer sunny day. In complete darkness, brightness can be reduced to a comfortable level. It is permissible to use and mode with automatic adjustment of brightness that works more or less adequately. The advantages of the screen should include the presence of an efficient oleophobic coating, no air gap in the layers of the screen and flicker, high contrast. To significant disadvantages - low stability of black to the rejection of the view from the perpendicular to the screen plane, distorted color balance, too wide color coverage and an unconnected dynamic light brightness adjustment. However, taking into account the importance of the characteristics for this class of devices, the screen quality can be relatively high.

Sound

ZUK Z1 sounds very interesting. Both the main speaker, and the connected headphones give high-quality, thick and rich, bright sound that remains clean at the entire level of volume, the supply of which is very high. Skip signal signal It is simply impossible, playing movies and games with such high-quality sound accompaniment turns into a comfortable pastime. Your own audio player in the smartphone is not used for this standard program Google Play Music. For manual control in the settings of the built-in audioofx sound system, there is a mass of the preset equalizer values \u200b\u200bseparately for the main dynamics and headphones. You can also additionally increase low frequencies and add a virtual volume. When telephone conversation, the interlocutors do not celebrate any special distortion. In the audience dynamics, the voice and intonation of a familiar interlocutor remain recognizable. FM radio in the smartphone is not.

Camera

ZUK Z1 is equipped with two modules of digital cameras with a resolution of 13 and 8 Mp. Front-camera Equipped with an Omnivision OV8868 sensor and a lens with a diaphragm F / 2.2. You can control the shooting using the hardware power key, there is a mode for defining persons. From convenient features: you can use a special mode for left-handed, and there is also an opportunity automatic installation The maximum screen brightness level when the camera is turned on. It happens comfortable with bright sunlight, so as not to climb every time in the brightness control settings. The quality of the resulting images of the images is average: the color rendition is natural, but the detailing and sharpness are sometimes chromassed.

The video camera is able to shoot with a resolution of up to 1920 × 1080, there is an ability to record with a speed of 60 frames per second. In the modes of the steady and slow survey, the device also removes with the resolution of Full HD. With shooting video in all modes, the camera copes perfectly, there are no complaints about image quality and smoothness, as well as to the quality of sound recording. True, with a strong wind noise, the noise reduction system does not cope anyway, it can be seen on the first roller.

  • Roller №1 (29 MB, 1920 × 1080 @ 30 fps)
  • Roller # 2 (36 MB, 1920 × 1080 @ 60 fps)
  • Roller # 3 (75 MB, 1920 × 1080 @ 30 FPS, SLO-MO)
  • Roller # 3 (2 MB, 1920 × 1080 @ 30 FPS, FAST)

Sharpness with the removal of the plan drops quite smoothly.

Macro movement manages well.

Good sharpness throughout the entire field of frame.

On the asphalt are visible traces of the noise, however the number of the car is distinguished.

The text is worked well, despite the software processing.

The foliage begins to merge on medium plans, but in general, sharpness is not bad.

Good sharpness over the field and by plans, although the left edge fails.

With room lighting, the camera copes not very well.

The camera turned out to be good. She copes well with day lighting, keeping a lot of details. At the same time, the sharpness is saved throughout the field of the frame and it falls very smoothly from the average plans to the distant. However, if the camera is lacking, it is not worth using the camera, since the sensor is clearly weak, and the noise is not very smooth. Optics are quite good, although the blur zone occurs on the left periodically. As a result, in the daytime lighting, the camera copes well with artistic and documentary shooting.

Telephone part and communication

Smartphone standard works in modern networks 2G GSM and 3G WCDMA, and also has the support of the fourth-generation LTE networks, but only three FDD LTE ranges (1800, 2100, 2600 MHz) are supported. That is, from the three most common ranges in domestic operators (B3, B7 and B20), the viewer can function only in two (B3, 1800 MHz, and B7, 2600 MHz), and not less common LTE FDD Band 20, 800 MHz, data The device is not supported. In practice, the SIM cards of the Beeline and MTS operators in the Moscow region, the smartphone was confidently registered and worked in 4G networks. The quality of the signal reception does not cause any complaints, the device confidently supports the connection in the premises and does not lose the signal in the zones of uncertain reception. Full list Supported by a smartphone ranges and frequencies is presented below:

  • TDD-LTE (Bands: 38, 39, 40, 41)
  • FDD-LTE (Bands: 1, 3, 7)
  • TD-SCDMA (Bands: 34, 39)
  • WCDMA (850, 900, 1900, 2100 MHz)
  • CDMA2000 (800 MHz)
  • GSN / EDGE (850, 900, 1800, 1900 MHz)
  • CDMA (800 MHz)

Also in the device there is support for Bluetooth 4.1, a Wi-Fi Direct is supported, you can organize a wireless access point through Wi-Fi or Bluetooth channels. USB 3.0 Type C connector supports connection of external devices in uSB mode OTG, however, for this will have to separately purchase a new type OTG adapter, since here C connector is used here.

The navigation module works with all three world systems: GPS (A-GPS), GLONASS and Beidou (BDS). There is no complaints to the speed of the navigation module, the first satellites are found at a cold start for the first tens of seconds. The smartphone is equipped with a magnetic field sensor based on which the compass navigation software is functioning.

The smartphone supports working with two SIM cards. Working with them in the menu is organized on one page visually and intuitively understandable. Any of the SIM cards can be assigned the main to organize voice calls, data transmission and sending SMS messages; When the number is dialing, you can also select the desired card with the corresponding buttons. With 3G / 4G networks, a SIM card can operate in any slot, but at the same time in this mode only one of them can function. To change the settings of the slots of the card, you do not need to change places - it can be done directly from the phone menu. Working with two SIM cards is organized according to Dual Sim Dual Standby, that is, a radio module is here only one.

OS and Software

Initially, in its own market in China, ZUK Z1 appeared with the new Lenovo's own manufacturer interface called ZUI, but later for the international market, a modification was supplied with officially pre-installed Cyanogen OS 12.1 of the latest version with support for the updates "by air" (OTA). The shell is familiar well, here the emphasis is not on the perverted of the appearance, and not to reorganize the sections, but to add, expand and improve existing functions and opportunities than the CyanogenMod interface and has gained universal popularity among mobile technology lovers. It is believed that this customized interface is faster, economical and more protected. But in appearance, the interface here is almost indistinguishable from the original Google Android with its Material Design. From features: Menu preset applications It is here, but it scrolls vertically, and not horizontally, like the rest. Working with gestures is not provided, but supported hardware buttons and added support additional features Settings of the notification panel. It is also possible to switch between profiles in which literally all are configured: from the working conditions of communication interfaces to the call melodies.

To independently install alternative firmware With CyanogenMod on the Chinese version of the device supplied with ZUI, the following steps must be taken.

For firmware, ADB and FastBoot will be required. Download and, copy them to the "Platform-Tools" folder (there is adb.exe there). Install USB drivers that will be offered when connecting a smartphone to a PC. In the smartphone, open options for developers (press "ZUI VERSION" several times) and enable "USB debugging" - USB debug mode. Connect the smartphone to the PC, approve in the depressing window debugging with this computer. In the Platform-Tools folder, call the commands window (click on an empty location right button with the SHIFT key).

IN command line Enter "AdB Devices". If the smartphone is connected correctly, in response you will get a combination of letters and numbers. Then unlock the button "FastBoot -i 0x2B4C OEM Unlock" command. Enter "FastBoot -i 0x2B4C Boot Z1.Recovery.testKeys.img". Custom recovery will be powder, and the smartphone will reboot to it. In the recovery menu, you will see three items beginning with "WIPE" - this formatting of different sections of the smartphone. Just in case, all three, controlling the mechanical keys of the device. Then select "Install Update" and the item indicating ADB.

Return to the computer and type "adb sideload z1.cyanogen.convert.signed.zip" on the command line "ADB SIDELOAD.SIGNED.ZIP". A very long process will begin installations CyanogenMod.. Progress can be tracked on the command line. After a successful completion, you will receive the message "Total Xfer: 1.00x". Smartphone will reboot in CyanogenMod and already installs last update international firmware. After that, you can safely resort to weekly updates "by air" and even do full reset - No specific additional actions for this do not have to produce.

Performance

The ZUK Z1 hardware platform is built on the basis of morally obsolete and already practically not found in modern smartphones Soc Qualcomm Snapdragon 801, which a few years ago performed as the Qualcomm flagship platform. In this case, the most advanced version of its MSM8974As is used, where the operating frequency of four KRAIT 400 cores is raised to 2.5 GHz. The GPU Adreno 330 is used as a graphics accelerator with a maximum core frequency to 578 MHz.

Volume random access memory The smartphone is 3 GB, from them initially at least 2.2 GB. The device has 64 GB of own memory, of which the user is originally available for it. own needs About 53 GB. The volume of built-in memory can not be increased due to mICROSD cardsBut there is the ability to connect to the USB port of external flash drives in OTG mode. It uses a quick USB 3.0 interface. In practice, the transmission of a 3 GB file from a computer through a USB 3.0 port to a smartphone takes 60 seconds, that is, the speed is about 51 MB / s. Through the USB 2.0 port port, the same file is transmitted in 2 minutes 10 seconds, that is, the speed is about 24 MB / s.

According to the results of testing ZUK Z1, demonstrated a very decent level of performance. The flagship platform from the past is still quite capable of competing even with much more modern flagship alternative solutions, such as Hisilicon Kirin 935 and MediaTek MT6795. Snapdragon 801 confidently demonstrates the results no less high than those of the SOC listed, both in complex and specialized graphics tests. At the same time, the platform is clearly inferior to its more advanced and more modern flagship succession Qualcomm Snapdragon 810, and even more far from the current exynos 7420, used in the most powerful modern devices. Samsung Galaxy S6 / S6 EDGE / S6 EDGE +.

However, if you move away from dry numbers of synthetic benchmarks, the lack of performance user ZUK Z1 will definitely not feel. This smartphone even now in its performance is at a level much higher than the average, its hardware features are still quite enough to perform any tasks, including demanding games.

Testing B. recent versions complex tests ANTUTU and GEEKBENCH 3:

All the results obtained by us when testing the smartphone in the most recent versions of popular benchmarks, we are conveniently reduced to the table. The table usually adds several other devices from various segments, also tested on similar recent versions of benchmarks (this is done only for a visual assessment of the resulting dry numbers). Unfortunately, within the same comparison, it is impossible to submit results from different versions Benchmarks, therefore, many decent and actual models remain "behind the scenes" - due to the fact that they at one time passed the "obstacle course" on previous versions of test programs.

Testing a graphic subsystem in 3DMark game tests, GFXBENCHMARK and Bonsai Benchmark:

When testing in 3DMark for the most productive smartphones Now it is possible to run an application in Unlimited mode, where the resolution of the rendering is fixed by 720p and is turned off by VSYNC (due to which the speed can rise above 60 FPS).

Browser cross-platform tests:

As for the benchmarks to estimate the speed of the JavaScript engine, it is necessary to always make a discount on the fact that they are significantly dependent on the browser in them, in which the comparison can be truly correct only on the same OS and browsers, and such an opportunity is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

Heatons

Below is the back of the rear surface, obtained after 10 minutes of operation of the battery test in the GFXBENCHMARK program:

It can be seen that heating is noticeably more localized at the top of the device, which, apparently, corresponds to the location of the SOC chip. According to the heat frame, the maximum heating was 38 degrees (at the ambient temperature of 24 degrees), it is not very much.

Video playback

To test "omnivities" when playing video (including support for various codecs, containers and special capabilities, such as subtitles), we used the most common formats that constitute the bulk of the content available on the content network. Note that for mobile devices it is important to have the support of hardware decoding of videos at the chip level, since to process modern options due to the processor nuclei are most often impossible. Also, it is not necessary to wait from the mobile device of decoding everything, since the leadership in flexibility belongs to PC, and no one is going to challenge it. All results are reduced to a single table.

According to the test results, the test suddenly pleasantly surprised the presence of support for all the necessary decoders, which are needed to fully play most of the most common multimedia files. That is, for successful playing them, it is not even necessary to resort to the help of a third-party player - for example, MX Player, although it will also be played in it with support for AC3 sound format, which cannot but rejoice.

Testing the features of the video output spent Alexey Kudryavtsev.

The MHL interface, like the Mobility Displayport, we did not find it in this smartphone, so I had to restrict ourselves to testing the image of the video files to the screen itself. To do this, we used a set of test files with one division by the frame with an arrow and a rectangle (see "Methods for testing the playback devices and displaying the video signal. Version 1 (for mobile devices)"). Screenshots with shutter speed in 1 C helped to determine the nature of the output of video files with various parameters: resolution ranged (1280 per 720 (720p), 1920 at 1080 (1080p) and 3840 at 2160 (4K) pixels) and frame rate (24, 25, 30, 50 and 60 frames / s). In tests, we used the MX Player video player in the "hardware" mode. Test results are reduced to the table:

File Uniformity Pass
4k / 30p Red marks point to possible problemsrelated to playback of relevant files.

By the output criteria, the quality of video files on the screen of the smartphone itself is good, since frames (or frames of frames) can (but not obliged) to be output with more or less uniform intervals of intervals and without frames of frames. When playing video files with a resolution of 1080p (1920 to 1080 pixels) on the smartphone screen, the image of the video file is output exactly along the screen border, one to one by pixels, that is, in the original resolution. The brightness range displayed on the screen corresponds to the standard range of 16-235 - in the shadows and in the lights displays all gradations of shades.

Battery life

The capacity of the built-in non-removable battery installed in the ZUK Z1 is almost the maximum to date for the conventional smartphone 4100 mA · h. With such powerful battery The device simply could not but demonstrate record indicators of duration autonomous work. Currently, ZUK Z1 is one of the most "long-playing" smartphones in the mobile market market, it is almost a record holder, few people can compare with it in terms of autonomy in any operating modes.

Measurements have shown that uninterrupted reading in the Moon + Reader program (with a standard, light theme, with autolistan) with a minimum comfortable level of brightness (the brightness was set per 100 cd / m²) lasted until the battery discharge for more than 21 hours. Without the auto-utility function in the FBReader program, these indicators will increase by a couple of hours. With unlimited viewing video from YouTube in high quality (720p) with the same level of brightness through home wi-Fi network The device lasted more than 16.5 hours. In 3D-games mode, the device worked for almost 7 hours.

At the same time, the smartphone is charged quite quickly. The device supports the function fast charging Qualcomm Quick Charge, in the end, completely the battery of the smartphone is charged in 2.5 hours.

Outcome

With all its good opportunities, ZUK Z1 is not so expensive. A novelty, designed to make a competitor to the MEIZU, Xiaomi and Huawei medium-level devices, is estimated at $ 285 equivalent. True, those few sellers who offer this model on the Russian market, the price varies already in the area of \u200b\u200b22-23 thousand rubles, and at such a price this apparatus there will be a lot of no less worthy competitors: for example, LETV One, Meizu MX5, and even OnePlus 2. Let's say that the same Letv One is widely supported by LTE frequencies in Russia and a much more modern 64-bit SOC. However, in general, all the listed devices are worthy of each other, and they play what is called, "on the same field."

The ZUK Z1 smartphone has any interest to the buyer. The device received a good and reliable, although not the most elegant body, a good big screen, magnificent sound systemThe satisfactory set of communication interfaces is quite powerful, let it already officially and not the flagship hardware platform and, of course, the outstanding level of autonomy - already for one thing to ZUK Z1 can be referred to in high attention.

Instructions for firmware QFIL firmware for ZUK Z1 and Z2.

The instruction is provided for informational purposes, please do not ask me questions on the installation of firmware !!!

Installing the driver.

For the goals set, a PC with Windows 7, 8 or 10 is required.

When you turn on the PC, press several times on the F8, select the download without checking the driver signature.

When installing Qualcomm_Diag_qd_loader_2016_driver appears window

We do not change anything, click Next and continue to install the driver.

After installing all 2 drivers and 1 programs, go to QFIL program.

Go to the Start menu and find the QPST software package and click right-click Mice on QFIL, run the program on behalf of the administrator.

After starting the QFil we see the following

Come in first thing to the tab Configuration-Firehose Configuration, Install the type of memory Device Type - EMMC, Install the tank to the item Reset After Download. Return to the main QFIL window.

When you changed the extension to open the file:
for ZUK Z1: Find a file prog_emmc_firehose_8974.mbn.and open
for ZUK Z2: Find a file prog_emmc_firehose_8996_ddr.elf. and open

Select file rawprogram0

Select the file patch0.

At the end of the selection procedure, we have the following window, but it is not possible to sew until the port is missing so the download button is not active.

For ZUK Z1. :
Turn off the phone, we connect usb cable only to PC, clamp volume button up And at the same time connect the cable to the phone.

For ZUK Z2:
We connect the USB cable to the computer and the phone and turn off the phone while you climb off volume swing upwhen you hear vibration, hold power button.

If not working, then:
Option 2 for ZUK Z2 ( for chipped phones, we use this option.):
Turn off the phone, plug the USB cable only to PC, Further at the same time !!! We carry out the following actions:
 press the power button + the volume button up + connect the cable to the phone.
It may turn out from the first time - turn off the phone and try again until the port is caught (see below).

Option 3 ( if it is not possible to translate the phone to the loader mode by previous options - no bricks fit !!!):
Turn off the phone, enter it into the FasBoot mode (clamp both volume keys and do not release them connect the phone to the PC).
Install an ADB from this instruction (if not yet installed), enter the command in the commands window on the PC:
fastBoot -i 0x2B4c OEM Reboot-EDL

Next we see the following result, the driver is installed and the port for firmware has become available (if the driver has been installed earlier simply caught the port)


Press the button Download- The firmware process will begin.
Important!!!
We wait until the firmware is completely powdered, in no case turn off the phone from the PC, even if it seemed to you that the firmware process stopped.
At the end of the firmware, the program will write a finish download, waiting for the phone itself to restart, only after that we turn off the phone from the PC.

Possible problems!
For those who have a mistake with the firmware Download Fail: Sahara Fail: QSAHARASERVER FAIL: Process Fail below tips on eliminating this error:
1) QFIL must be launched on behalf of the administrator.
2) The path to the folder with the firmware is too long and / or contains Cyrillica - unzip the firmware along the path C: / ZUK and go again.
3) Use the original cable for firmware;
4) Change your computer or USB port and go again;
5) Download QFIL version 2.7.453 , Delete QFIL, which is now set, clean the Program Files (x86) \\ Qualcomm folder, ProgramData \\ Qualcomm, AppData \\ Roaming \\ Qualcomm, we set the QFil version 2.7.453 and sew again.
6) In the device manager at the Qualcomm driver it is possible worth a triangle with an exclamation mark, reinstall in the "without certificate authentication" mode and without rebooting the firmware.
7) Type file System It is worth UFS a not EMMC, change on EMMC, restart QFil and try to flash the firmware again.

If the phoned phone
1) without panic.
2) You need to turn off the phone to once again flash it via QFIL from the off state. In the network there are many methods for this - either waiting for the phone completely discharge itself, or use people from the Internet.
I have only coupled phones for a couple of times, and both times the phone constantly rebooted - you can turn off the phone from such a brick state. You can climb the off key and keep, the phone is rebooted, the LED is lit, continue to keep the shutdown key at the moment When the LED goes out - press the shutdown key - the phone must turn off (the sign of the phone turned off - the screen should not be lit, the LED must be turned off).
