I greet the members of the Expert Club, as well as all the guests who have visited this page.
It is customary for us to be afraid, if not afraid, of too cheap smartphones. Like, if life forces you to use such a device, then that's it, write it up! They take pictures very badly, the screens are just disgusting, "slows down" terribly, and if it is an operator's smartphone, it will also be locked.
Therefore, on holidays it is already customary to wish not only happiness, health, good luck, but also that fate does not bring smartphones for three thousand rubles (just kidding). So, what am I for: fate brought me together with such a smartphone. And I even left for two weeks. And you know what I can say after this test? I could have walked with him further!
Opening the cards: we are talking about Vertex Impress Luck - the most inexpensive smartphone from the first largest B-brand on the modern Russian market of smart phones. Vertex Impress Luck can be bought for over 3 thousand rubles. I don't even know what to compare it with. Probably, in Moscow or St. Petersburg, this is the average bill for a dinner in a cafe for two.
Vertex Impress Luck left a pleasant impression for a reason. There is every reason to believe that the appearance of this rather successful device for less than three rubles is a direct consequence of the policy of the Russian brand Vertex. According to his own account, Vertex has three key principles. Be the first in a) quality, b) design and c) technological chips and / or price. With regard to quality, the situation is as follows: the defect rate for Vertex is on average around 2%, for other local brands of smartphones - both 5% and 10%. 2% is generally the level of HTC or LG, for example.
Well, before proceeding to the story directly about the smartphone, I will voice two more points. First: Vertex Impress Luck became the first in terms of sales of smartphones during the New Year sales in the MegaFon network of showrooms. Second: in 2017, Vertex ranked sixth in terms of smartphone sales in Russia. And the first is among local Russian brands... This is probably also a consequence of the “three basic principles” approach described above.

Appearance
I remember when I first took the Vertex Impress Luck out of the box, I was amazed. The reason for the amazement was that it has an extremely pleasant body material - such a velvety plastic, soft to the touch. No, this is not a typical rubber with a bad smell, like many smartphones with a price of 3-4 thousand. This is just such a plastic velvet. After that, you somehow immediately forget about the budget essence of Vertex Impress Luck - it feels more expensive than it really costs.
The design of the back cover of the Vertex Impress Luck resembles the iPhone 5c, although it did not have a black version, but if we discard the color, then there is definitely a similarity.
By the way, about the color. Vertex Impress Luck can be not only black, but also golden. The last option, I think, is even nicer. But, alas, I had a less bright black version.
The back panel of the Vertex Impress Luck is removable. Under it is, again, a removable battery of 2,200 mAh, as well as three card slots at once - two for SIM cards, one for a USB flash drive. By the way, this is an important plus of most cheap smartphones: only they allow you to change the battery without visiting the service and put three cards at once! Even in devices that are more expensive than 10 thousand you will not find this anymore, there are only built-in batteries and, most often, combined slots for cards. Or two SIM cards, or one SIM card and in addition to it MicroSD. At Vertex Impress Luck, I repeat, everything is old-school, as in the old days, when absolutely smartphones were a) collapsible and b) comfortable.
 |  |
The back has slots for the camera, flash, and speaker. The speaker is of medium volume - you can, of course, listen to a song for two or three, but you can't arrange a disco for a crowd of friends here.
There is no light sensor in the smartphone, and this is just a reflection of its budget essence. You cannot adjust the brightness of the screen automatically, only manually. But on the other hand, there are other components that are usually located above the display in smartphones. These are: proximity sensor, speaker and front camera. The voice of the interlocutor Vertex Impress Luck transmits well, without rustling and metallic notes, the proximity sensor extinguishes the screen during the call, but the 2 megapixel front camera with flash ... More on it later, but you probably already understood that photo masterpieces with you can't do it.
Three standard Android smartphones are located under the display touch buttons... Everything is good with them, except for one thing: there is no backlight. So in the dark you have to poke at random. This is a minus, but what to do.
But there are no questions about the power and volume keys. They are on the right and are very conveniently located. It is easy to grope them - you will definitely not be mistaken and confused.
On top of the case there is a MicroUSB port and a standard headphone jack. The ports are located nearby, but you can plug in both the headphones and the cable at the same time. So listening to music while the Vertex Impress Luck is charging is real.

Screen
Often, smartphones for 3,500-4,000 rubles have screens with a diagonal of 4.5 inches, that is, they are very small and not very convenient for browsing the Internet and playing games. Vertex Impress Luck offers an honest 5 inches, but not simple, but flavored with an IPS-matrix. Yes, obviously not the most expensive one. Yes, with insufficient quality color reproduction - the colors go into warm tones. And yet, this is IPS: black is black, not gray, viewing angles are wide, colors are saturated.
In general, we can state that Vertex tried and put in an ultra-budget smartphone not a cheap TN-matrix (as in the overwhelming majority of state employees), from which it hurts the eyes, but IPS. This, of course, cannot but rejoice.
And yes, about the color temperature, which is shifted to a warm area. Vertex Impress Luck has a variety of tools under the name MiraVision (developed by MediaTek) that allow you to customize the picture. Including making it colder, bringing it closer to the standard. So the minus described above, in general, is not a minus.

It remains to add that the screen resolution is 480 x 854 pixels. At the same time, the display supports the simultaneous pressing of only two fingers. Although for browsing the Internet, calls and correspondence, this is quite enough.
Software
Vertex Impress Luck is based on operating room Android systems 7.0 Nougat.
The main screen has only one desktop.
The menu is implemented as a single page with a scroll bar. In my opinion, the ribbon menu is inferior to the page menu in terms of navigation speed. The smartphone is practically not cluttered with third-party software, and the additional software that is installed can be easily removed.
And yes, Vertex Impress Luck has an over the air update. I even managed to catch one update. After installing it, I did not fix anything new, so, apparently, the developers just re-optimized something.
Camera
The main camera has a 5 megapixel matrix. The camera is not equipped with autofocus.
You shouldn't expect anything in terms of photo capabilities from a smartphone. The examples show that the images are of poor quality. The image is blurry and lacks sufficient color.

The front camera is equipped with a 2 megapixel matrix. There is no autofocus, but there is a flash. The quality of the obtained photos is not that bad, considering the quality of the images from the main camera.
In work
To begin with, I will say that Vertex Impress Luck is a 3G smartphone. What else could you expect? For such a cost, LTE does not exist, let's get back to earth and stop dreaming about (so far) unrealizable. In general, closer to the point: the Vertex Impress Luck uses a MediaTek MT6580 chipset with four Cortex-A7 cores (up to 1.3 GHz) and a simple Mali-400MP graphics. There is 1 GB of RAM and 8 GB of flash memory. That is to say, the required minimum.
But here it is worth making a reservation: it is very possible to play on this device! Yes, you will not see all the beauties invented by the authors of the games, they will be mercilessly cut off. And yet the same Asphalt 8 runs great at low / medium settings. WoT Blitz is coming too - you can easily "hunt" on a warm May evening.
Synthetic test results.

There are no questions about the wireless modules, everything works fine. Even navigation, which you really don't expect from a smartphone of this class, and even on the MediaTek chipset. Usually, you expect only glitches from such devices (only a little more expensive, since the closest competitors of Vertex cost from 3,500 rubles), but with Vertex Impress Luck everything works more or less normally.
Autonomous work
2200 mAh battery gives one and a half to two days of work. Is this a lot? Is it not enough? This, of course, is not the ultimate dream, but pretty good. Even expensive flagships usually don't work anymore. So Vertex Impress Luck has everything within the market average. Well, let me remind you once again that the battery is removable. You can buy another battery (it will cost 500 rubles) and use it in turn with the one that comes with the kit.
Output
The first for the price is what the developers at Vertex call Impress Luck. Yes, the device with its price of just over 3000 rubles is really the cheapest on the market. The cheapest - but clearly not the worst. He is very decent, if not "good". The case is like, the screen is the second like, the hardware is like again, the battery is no better and no worse than others, the software is also like. Dislike only for cameras, but cameras are not an easy thing, even smartphones for 10,000 rubles do not always take pictures well.
That's all for me, make smart purchases and enjoy new acquisitions.
I express my special gratitude to the administration of the Experts Club for the opportunity to post this review.
Accelerometer(or G-sensor) - sensor of the device's position in space. As a primary function, the accelerometer is used to automatically change the orientation of the display image (vertical or horizontal). Also, the G-sensor is used as a pedometer, it can be controlled by various functions of the device by turning or shaking.
Gyroscope- a sensor that measures the angles of rotation relative to a fixed coordinate system. Able to measure angles of rotation in several planes at the same time. The gyroscope together with the accelerometer allows you to accurately determine the position of the device in space. Devices using only accelerometers have lower measurement accuracy, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- a sensor, thanks to which the optimal values of brightness and contrast are established for a given illumination level. The presence of the sensor allows to increase the operating time of the device from the rechargeable battery.
Proximity sensor- a sensor that detects when the device is close to the face during a call, turns off the backlight and locks the screen, preventing accidental presses. The presence of the sensor allows to increase the operating time of the device from the rechargeable battery.
Geomagnetic sensor- a sensor for determining the side of the world to which the device is directed. Tracks the orientation of the device in space relative to the earth's magnetic poles. The information received from the sensor is used in cartographic programs for orientation on the ground.
Atmospheric pressure sensor- sensor for accurate measurement of atmospheric pressure. It is part of the GPS system that allows you to determine the height above sea level and speed up the location.
Touch ID- fingerprint identification sensor.
Illumination / Approximation
Satellite navigation:
Gps(Global Positioning System) is a satellite navigation system that measures distance, time, speed and determines the location of objects anywhere on Earth. The system is designed, implemented and operated by the US Department of Defense. The main principle of using the system is to determine the location by measuring the distance to the object from points with known coordinates - satellites. The distance is calculated from the signal propagation delay time from its sending by the satellite to being received by the GPS receiver antenna.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measuring principle is similar to the American GPS navigation system. GLONASS is intended for operational navigation and time support of land, sea, air and space-based users. The main difference from the GPS system is that the GLONASS satellites in their orbital motion do not have resonance (synchronization) with the Earth's rotation, which provides them with greater stability.

Positioning
The previous Luck did not support 4G networks, did not have NFC, but at the same time had one of the most affordable prices on the market for a 5-inch device. By the end of 2018, it could be bought for 3,500 rubles, which made it one of the most popular and affordable devices. For example, at MegaFon this model became number one in sales at the end of the year. They tried to make the updated model no worse, but add NFC and 4G support there. For a budget Android smartphone, select the version operating system obvious - Android Go. Small amount of memory, rather modest performance, but all this for little money, you can't expect much from the device.
Considering that the ruble exchange rate jumped throughout 2018, the previous models remained on the market, they were slowly washed out. Against their background, the new items seemed indecently expensive, the same Luck 4G NFC costs 5,490 rubles. You remember the situation at the beginning of 2018, and it seems that for this money you could buy something more interesting. But the problem is that a year later the prices have changed, and more productive solutions start at 7,000 rubles, here you can find models with 2 GB of RAM, and this parameter becomes the main one for such devices.
In my opinion, Luck 4G NFC is an example of one of the most inexpensive smartphones with 4G and NFC, it was in this capacity that he was conceived. How important these parameters are for the consumer is a question, but expect that any Android Go smartphone will be comfortable, not necessary, these are always performance flaws. Let's take a look at the pros and cons of the device.
Design, dimensions, controls
The model is available in two colors - classic black and dark blue. In both versions, the backrest is made of velvety plastic, very pleasant to the touch. Look at the blue, I like it. Bright, attractive and somewhat youthful device, well suited for children.
Surprisingly, they retained the row of touch keys, apparently so as not to take up space on the screen, which is not so large. The back cover is removable, under it you can see slots for two nanoSIM cards, as well as a memory card. The build quality of the device is excellent, there are no complaints about it. This distinguishes the model from many analogues in this price group.
On the right side there is an on / off button and a volume rocker in the same place. The microphone is placed on the bottom end, and on the top there is a microUSB connector, as well as a 3.5 mm one.
Display
The technical characteristics of the screen are as follows: 5 inches, 480x854 pixels, IPS, automatic brightness control. The screen has small viewing angles, but when viewed directly, the picture is quite bright and saturated. Supports up to two simultaneous clicks. The picture fades in the sun, but remains readable (due to winter time, there was no very bright sun, but I don't think the screen will show itself somehow unusual here). The fact that there is adaptive brightness control is a big plus, usually in models of this class this feature does not exist.
Battery
The battery in this phone is removable, the capacity of the Li-Ion battery is 2000 mAh, which gives us up to 3.5 hours of talk time and up to 130 hours of standby time. Charger 5V / 1A, full charge takes about 2 hours.
Due to the chipset used, the operating time of the device greatly depends on the tasks that you entrust to it. For example, when making calls, SMS, messengers, the device lives quietly for one day. But if you are actively watching videos or playing casual games (and others will not go here), then it will turn out half a day at most, it will be discharged before our eyes. Savvy users will get up to two days of work with an hour of calls.
Video playback time at maximum brightness (HD video in MX Player) is 4 hours. Which, considering the chipset, isn't that bad at all.
Memory, platform, performance
The device is built on the MediaTek MT6739 platform (4 Cortex A53 cores up to 1.28 GHz, PowerVR Rogue GE8100 graphics coprocessor). The processor cannot be called efficient, it is rather "dead" in conjunction with the memory. The screen shows slow opening of applications, they freeze, and heavy applications do not open at all. This is a minus of Android Go and the hardware used in most of these first-price models. You have to pay for everything, in this case the low cost has a downside.
Unfortunately, the AnTuTu test has recently refused to work on many models, this one is no exception, so this test was not.
The amount of RAM is 1 GB, which is extremely small even for Android Go. The built-in memory is 8 GB, of which about 2.5 GB is available to you. You can install memory cards with a capacity of up to 32 GB or cards up to 128 GB, but then they will need to be formatted in the phone.
Communication capabilities
4G support is implemented well, but do not expect prohibitive speeds, everything is quite simple. GPS work is not satisfactory, everything works well, but there are delays during navigation, this is due to the overall performance of the system. Wi-Fi has support for the second band, which is unusual for a budget device (however, the presence of VoLTE is just as unusual). There is NFC, with which you can set up Google Pay, read the Troika card, and so on. Everything works without any problems or flaws. For a budget device, the presence of NFC is extremely unusual.
Camera
The front camera is 2 megapixels, no autofocus. The quality of the photos is very, very bad, however, see for yourself.
The camera interface is very simple, the main module is 5 megapixels, while the quality of photos is also poor. You can also see this for yourself.
Sample photos
Software
There is nothing to say, this is a standard Android 8.1 Go Edition, you should not wait for updates to new versions, but at the same time, security updates are constantly coming to this device, which is welcome. Standard applications from Google have a Go prefix, these are their lightweight versions.
The device has a built-in FM radio, it works only with headphones, as they act as an antenna. There is also file manager and a voice recorder.
Impression
The phone's ringtone is good, you can hear it from the outerwear. You don't always feel the vibration alert. The connection quality is good, there are no complaints. Yes, this is a budget device, but everything is fine with the connection.
There are many models on Android Go on the market in the budget segment, most recently we had an Alcatel 1, it is very similar to the Luck 4G NFC in question, but it does not have NFC support, although the platform and many characteristics are similar.
At 4,000 rubles, the Alcatel 1 looks more interesting if you don't need NFC. The design of the devices and the aesthetics are different, but the performance and capabilities are, plus or minus, comparable. Most C-brands have offerings at about the same price as the Luck, but lack NFC. And here you need to decide what you need and how much, and if you plan to use mobile payments, then there are no alternatives as such. If not, then you can look at other parameters, of which the battery and appearance become the main ones.
If you add a little and look at devices that cost from 7,000 rubles, you will get fundamentally different possibilities - different performance, more memory, a fingerprint sensor, better screens... An excellent model in this segment can be the Impress Blade.
On the other hand, if there are budget constraints, then it might make sense to look at 3G devices and the usual Luck, which costs about 3,500 rubles.
Accelerometer(or G-sensor) - sensor of the device's position in space. As a primary function, the accelerometer is used to automatically change the orientation of the display image (vertical or horizontal). Also, the G-sensor is used as a pedometer, it can be controlled by various functions of the device by turning or shaking.
Gyroscope- a sensor that measures the angles of rotation relative to a fixed coordinate system. Able to measure angles of rotation in several planes at the same time. The gyroscope together with the accelerometer allows you to accurately determine the position of the device in space. Devices using only accelerometers have lower measurement accuracy, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- a sensor, thanks to which the optimal values of brightness and contrast are established for a given illumination level. The presence of the sensor allows to increase the operating time of the device from the rechargeable battery.
Proximity sensor- a sensor that detects when the device is close to the face during a call, turns off the backlight and locks the screen, preventing accidental presses. The presence of the sensor allows to increase the operating time of the device from the rechargeable battery.
Geomagnetic sensor- a sensor for determining the side of the world to which the device is directed. Tracks the orientation of the device in space relative to the earth's magnetic poles. The information received from the sensor is used in cartographic programs for orientation on the ground.
Atmospheric pressure sensor- sensor for accurate measurement of atmospheric pressure. It is part of the GPS system that allows you to determine the height above sea level and speed up the location.
Touch ID- fingerprint identification sensor.

Satellite navigation:
Gps(Global Positioning System) is a satellite navigation system that measures distance, time, speed and determines the location of objects anywhere on Earth. The system is designed, implemented and operated by the US Department of Defense. The main principle of using the system is to determine the location by measuring the distance to the object from points with known coordinates - satellites. The distance is calculated from the signal propagation delay time from its sending by the satellite to being received by the GPS receiver antenna.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measuring principle is similar to the American GPS navigation system. GLONASS is intended for operational navigation and time support of land, sea, air and space-based users. The main difference from the GPS system is that the GLONASS satellites in their orbital motion do not have resonance (synchronization) with the Earth's rotation, which provides them with greater stability.
