Samsung Galaxy A3 (2017) is the most affordable model of the three presented in Russia, but it has a lot of disadvantages. Externally, apart from the more compact dimensions, this smartphone does not differ from its counterparts. It is also available in four different designs: blue, gold, pink and black.

Anyway, what is hiding under a beautiful and stylish design? We'll answer that question in our 2017 Samsung Galaxy A3 review as well as its looks.

Design and screen

Like other devices in this series, the Galaxy A3 is covered on both sides with durable Corning Gorilla Glass 4, and the frame is made of metal. The rounded edges of the back and 2.5D glass make the phone fit perfectly in the hands. The bezels are a little too big - this is confirmed by the not very best screen-to-body ratio, which is 67.9%.

On the right is the power / unlock button, while on the left we see the volume keys. Below the screen are the traditional capacitive Application Manager and Back keys with their own backlight, as well as the Home button with a built-in fingerprint sensor ”, which works by the touch method.

Got a 4.7-inch Super AMOLED display with a resolution of 1280x720 pixels, while the pixel density reaches 312 dpi. This value is far from the record, but the clarity of the picture will not disappoint you. Even small text remains readable and smooth, and the picture remains visible under the bright rays of the sun.

One of the most interesting features of the updated A3 is the Always On Display. This function allows you to display such important information like date and time, notifications, calendar, music player control buttons and more. Everything that is needed will be shown on the screen when the phone is asleep, making AOD an extremely handy feature of this phone.

Very slim body the phone is manufactured in accordance with the requirements of the IP68 standard, which makes the “handset” completely waterproof. The user can dive with a smartphone to a depth of 1.5 meters for up to 30 minutes. Naturally, the device is also protected against dust penetration.

Cameras

The new Galaxy A3 (2017) has a pair of lenses, one on the front and one on the back. The front camera boasts an 8-megapixel sensor, which means it is capable of taking pictures at a resolution of 3264x2448 pixels. The video is also good - Full HD-resolution at 30 frames per second. The main camera received a 13-megapixel sensor, which can take pictures of noticeably better quality and resolution. Unfortunately, the phone is not capable of recording 4K video, but 1920x1080 will be enough for most people.

Near the main lens, which by the way does not protrude from the back cover, there is a single LED flash. She copes well with her task.

Processor and memory

At the heart of the Samsung Galaxy A3 2017 is the Exynos 7870 processor, which has 8 energy-efficient Cortex-A53 cores in its arsenal. They operate at 1.6 GHz, which is sufficient for everyday tasks. There is a graphics accelerator Mali-T830 with two cores on board, ensuring the performance of 3D games at acceptable settings.

The hardware platform also includes 2 GB of RAM and 16 GB of storage. If the built-in memory is not enough, then the user can expand it using a microSD memory card. This is possible only if the second SIM card slot is not occupied by it. Unfortunately, Samsung decided to save some money and implemented a hybrid tray, so you have to choose.

It is worth emphasizing that out of 16 GB of ROM, only 9.7 GB is available to the user.

Autonomy

A 2350 mAh battery is responsible for the autonomy of the mobile device. This, according to the manufacturer, is enough for 12 hours of surfing on the 3G Internet or 16 hours on 4G. If you only use Wi-Fi, the built-in battery will last for 17 hours of browsing.

The battery is naturally not removable and it also doesn't support fast charging, which is definitely a downside. Given the relatively small capacity of the autonomous power source, the new Galaxy A3 (2017) will not charge for a long time.

Wireless connection

This phone is equipped with a module that allows it to work in networks fourth generation(Cat.6). Both SIM card slots are compatible with the Nano type, and the second of them can also be used to increase the amount of internal memory.

The device is obviously equipped with Bluetooth version 4.2, Wi-Fi with support for dual bands and the latest 802.11 ac standards. The picture is adorned with the presence of USB Type-C (USB 2.0) and an NFC module, thanks to which the company implemented the work of a mobile payment service Samsung Pay.

The A3 chip incorporates global positioning systems such as GPS, A-GPS and GLONASS, but this is not surprising.

Software

Samsung Galaxy A3 (2017) runs on Android 6.0.1 Marshmallow platform, which doesn't add to its interest. One way or another, the smartphone is preinstalled with the latest version of the Samsung Experience user interface, which fascinates with its ergonomics and a set of tools.

The user becomes available to the capabilities of flagship smartphones, including changing themes, application icons, Samsung Cloud, the "Protected folder" function, a new system maintenance tool "Optimization", two new power saving modes and much more.

Conclusion

The updated model, both externally and internally, looks good enough, but, of course, it was not without its drawbacks. Of interest is the fingerprint scanner, which is enough to touch to unlock the screen, waterproof case and even autonomy due to the energy efficient chipset. But the hybrid SIM card slot is not very happy.

You will also not be thrilled with the camera and the price of the new item. Now Galaxy A3 (2017) will cost you 23 thousand rubles. Yes, considering all the pros and cons, you will be satisfied with the phone.

Samsung Galaxy A320F A3 2017 is simple, powerful and durable. We talk about the interface, performance in comparative tests, new features, sound and camera!

Samsung Galaxy A320F A3 - the junior representative of the A line, has always been considered a compromise solution for those who wanted to have premium smartphone however, the high performance of the older models was not required. The 2017 model is no longer in the middle. This is the second part of the Samsung Galaxy A3 2017 review. We invite you to familiarize yourself with the main advantages and disadvantages of the model, body, display, battery and autonomy of the device.

Android for Samsung Galaxy A320F A3 2017

The company is in no hurry to install the latest software versions on its devices. Samsung Galaxy A3 2017 came out with marshmallow Android 6.0.1 on board (in principle, like the A series of 2016). But the Android 7.0 update for the Galaxy A3 2017 is expected in the first half of this year. Note that the current version of the software is already working on the much expected Grace UX, inheritor of TouchWiz.

Smartphones in 2017 are the first of the A-series to receive the function Always On Display- shows three main applications: time, date, calendar with a number additional settings... The function also shows new notifications on the display (a feature that does not work with S7).

In low light conditions, the image dims and turns off completely when the Samsung Galaxy A3 2017 is in your pocket.

Samsung Galaxy A320F A3 2017 equipped with a fingerprint scanner to protect your smartphone, access applications and websites. The fingerprint readout time is not the fastest, but the sensor works on par with the S-flagships.

The user can also create a secure folder with personal files and applications: photos, mail, documents.

For smartphones, Samsung Galaxy A3 2017 provides 15Gb of branded cloud storage, where you can save everything: from contacts to letters and media files. The user decides for himself which files are synchronized and saved via the mobile Internet, and which - exclusively via Wi-Fi.

Home screen on Samsung Galaxy A320F A3 2017

The home screen has undergone the smallest changes. Briefing is also available to users on the left swipe (which is mercilessly annoying and, fortunately, can be disabled). The user can apply themes and install icon packs to change the look of the desktop.

The notification panel remains almost the same. When minimized, the user sees notification icons, clock, charge level, active connections and SIM cards. The open curtain offers the user more settings... Traditionally, under the settings menu there is a slider for adjusting the brightness of the screen, and under it is the Google search box.

In the curtain of the Samsung Galaxy A3 2017, there is a new option to block notifications, which allows you to turn off annoying reminders from applications and games. User opinions differ on the design of the new menu. Someone likes schematic minimalism, while others are critical of the curtain. But you don't have to choose. It is not possible to rollback Samsung Galaxy A 3 2017 to earlier Android versions without losing the warranty.

One of the significant shortcomings of the Galaxy A3 2017 software is the lack of a multitasking mode as in the older ones. Galaxy models A5 2017 and Galaxy A7 2017. User cannot open multiple apps in single screen mode. Switching between active applications has not changed in any way. Everything is presented and works the same as in the previous version of the device.

The main menu has also changed somewhat functionally. The main changes concern the search by applications. If previously, on request, the search offered you only installed applications, now applications from Galaxy Apps(can be set Play Market).

With the introduction of Grace UX, the shell interface has changed little. The operating system takes up a lot of space: out of 16GB of internal memory, only 10GB is available to the user.

Samsung Galaxy A320F A3 2017 Review: Game Launcher

Game launcher- a new option for the Samsung A-series - a separate folder for games for quick access. The folder contains all games and applications, control and customization functions are available. Game Lauhcner simplifies and organizes the main menu for those who install many games and entertainment applications on their smartphones. The large number of icons in the general menu make it difficult to find and access.

In the Game Launcher settings, the user can manage notifications from applications, quickly switch between games, disable touch buttons to avoid accidental clicks, video screen capture for recording gaming sessions. The function is useful for those who upload videos of the game's level walkthroughs on YouTube. Optionally, the user can activate a selfie camera and create a 2-in-1 video. Settings allow you to select the resolution and recording quality if the device memory is limited.

Game Launcher in Samsung Galaxy A320F A3 2017 saves statistics of all games that the user has played on the device. The application tracks not only the results and points, but also genres, and shows what the user plays more: races, strategies, logic toys, etc.

Game Launcher also allows you to optimize your phone's performance: change settings without having to go to the main menu.

Performance Samsung Galaxy A3 2017

The Samsung Galaxy A3 2017 is powered by the Exynos 7870 Octa processor. Built on a 14nm process technology, the chip uses all 8 Cortex A53 cores (1.6GHz each) and a Mali-T830 GPU. The chip is paired with a very mediocre 2GB of RAM. This is enough for the ordinary everyday use(messengers, social networks, calls, internet), but may not handle heavier games.

The performance of the Samsung Galaxy A3 2017 is quite mediocre.

Speaker volume in Samsung Galaxy A3 2017

Samsung Galaxy A3 2017 has one speaker, loud enough, located atypically, it is practically impossible to cover it with your palm during use (intentionally or not). The sound is loud and clear, even at maximum limits.

Comparative test of sound in smartphones:

A little about the sound at the output

The Samsung Galaxy A3 2017 delivers crisp, clear, high-quality sound at the output, which no one expected from the younger model. The top is clear, the bass is voluminous, the middle is clean. No subsidence. Even at maximum volume, the sound remained crisp and rich. Note that a lot depends on the quality of the headphones through which you will listen to the tracks, as well as on the quality of the file and the source - from where you pull the music: a cloud, a social network or a file is stored in the phone's memory.

Messages and keyboard

Contrary to everyone's expectations, Samsung offers a standard SMS messenger. It was previously thought to be replaced by Google Allo, but this application did not receive proper user support and, despite the large number of downloads, the application is little used.

The interface is simple, all the main functions and settings are hidden in the side menu called by swipe. The menu offers quick access to all media files received and transmitted via short messages, blocking incoming / outgoing messages, disabling notifications from specific contacts, marking priority messages (always shown in the TOP, regardless of the date of receipt or update of the conversation). Messages support emoticons and transfer of graphic files.

Text input is performed using a standard Samsung keyboard with many custom settings: you can change the width and height, hide unnecessary lines and symbol buttons. You can change the color scheme and increase the contrast.

Camera Samsung Galaxy A3 2017

The camera in the Samung Galaxy A3 2017 is mediocre. The front camera has improved in megapixels from 5MP to 8MP, while the main camera has not changed compared to the version of the previous year.

There is no optical stabilization in the smartphone, and there is also no Dual Pixel technology. This is a touch-sensitive AF phase detection technology designed to track a moving subject smoothly and clearly in sharp focus.

While the Galaxy A3 2017 inherited a lot of camera tricks from the Samsung S7, it did not get the main functions that determine the quality of the picture.

Pro mode is available to users, but the settings are very limited. The user can only change the ISO and adjust the exposure, no more. S-flagships offer much more customization, due to which you get the highest quality pictures.

Examples of photos from the camera Samsung Galaxy A3 2017:

Conclusion

• Samsung Galaxy A3 2017 virtually unrivaled, the 4.7-inch smartphone market is shrinking rapidly. And those gadgets that are available now do not offer such TX as the younger model of the A-series.
• The device received premium chips, which were previously only available in S-flagships: AOD, dust / water resistant.
• Autonomy of the device at a height: 93 hours of moderate use (with AOD off) is astounding. A3 2017 will give odds in the autonomy of both Samsung S7 and iPhone 7.
• Camera- not the strongest side of the smartphone, but copes with everyday tasks with a bang!

Photos in the interior

If you have read the 2017 A5 review, I advise you to read the sections “Positioning”, “Display”, “Battery”, “Camera”, “Performance” and “Impressions”, since the rest of the text is almost the same, little things have changed, since these the devices are built on one tracing paper.

Positioning

Most of the manufacturers have completely abandoned the segment of compact smartphones, for some reason it is believed that a small phone should be outdated, not the most modern. There are three companies on the market that produce such devices - Apple (iPhone SE model), Sony (Compact series), and Samsung. In A3 2017, the desire of some buyers to get a small, compact phone was realized. The relatively small screen diagonal of 4.7 inches determines the scenarios for using such a device - first of all, it is needed for calls, and secondly, for social networks, instant messengers and web browsing. This smartphone can be safely considered as a second phone, in this capacity it is almost ideal - it works for a long time, has a balanced, modern set of functions. But as the main device for those who are not looking for a large screen diagonal, accustomed to compact models, it is good.

On the side of this model, a set of functions comparable to older devices, although a number of features were removed in the A3 2017 compared to the A5 / A7 - the phone has simpler front and main cameras, a lower screen resolution (HD, not FullHD), there is no fast battery charging , which, however, is not critical, the charging time remains comparable, since the battery capacity is also lower. All pluses in the form of Samsung Pay (NFC / MST), IP68 water resistance remains. As well as the use of exactly the same materials that distinguish the model from many classmates, it is made perfectly. And, perhaps, this is one of the few compact smartphones on the modern market - the difference between this model and 5-inch devices is very tangible, the impressions from them are very different. Moreover, these differences are both a plus and a minus, and depend directly on what you are used to.

Design, dimensions, controls

In the A-series, the design is to some extent inherited from the older models, the same body materials, no noticeable simplifications and savings. The A3 model looks expensive and stylish, regardless of the color you choose. There are four color solutions in total, there are no pink phones in Russia yet.

I have a black A3, it is classic and looks good. The mirrored surface reflects the surrounding world, plays in the light, the device looks very interesting, and handprints are practically invisible. I will add here that the screen with a splash screen can always work (the AlwaysOn Display function), which none of the competitors has. In the end, we get an unusual device that has no analogues on the market, it can be distinguished from any other at first glance.

If we talk about what color is the best, then I like blue, it is a delicate shade, very unusual, perfect for girls, however, see for yourself.

Please note that the front and back panels are in the same color, as well as the side metal edging (6000 series aluminum). The device looks good in pink too, but it is definitely only for girls.

The gold-colored phone is somewhat simple-minded, but everyone has their own tastes here.

The fact that the device has a glass back and front part does not interfere with it at all, since Corning Gorilla Glass 4 is quite reliable and protected from accidental drops, although here someone is as lucky. In terms of mechanical protection, this device is completely identical to the Galaxy S6 EDGE, the quality is on par. I once recorded a video about how this phone survives when hitting sharp objects or asphalt, you can watch this video.

The innovation of the 2017 A-series was the protection against water, which was taken from the S7 / S7 EDGE, the implementation is exactly the same. The SIM-card tray is protected by rubber gaskets, the microphones and the speaker have membranes, the level of protection is IP68, which allows the phone to be at a depth of 1.5 meters for up to half an hour. This does not mean that the phone needs to be washed under water and even more so with soap or something similar. But if you drop it into water, then nothing will happen to it. There are no water-resistant models in this price segment.

Now about the controls. There is a mechanical key under the screen, a fingerprint sensor is inscribed in it, it is simplified compared to S7 / S7 EDGE, it works a little slower, but there are no problems because of this. Nice solution that just works. On the sides of it there are two touch-sensitive keys.

On the left side there are two volume keys, on the right side there is an on / off button. At the bottom and top ends - on the microphone, there is a noise reduction system, it does its job perfectly, you can be heard well in any conditions, even when the wind blows strongly into your face.

At the bottom there is also a 3.5 mm jack for a headset or headphones, as well as a USB Type C connector for a charger. At the top there is a tray for a nanoSIM card and a memory card or two SIM cards. This is a combo tray, so it's worth remembering that in the A5 / A7 you can install both a memory card and two SIM cards at the same time.

The loudspeaker was placed on the right side surface, due to this it can overlap in a pocket, it will not be very well heard. The speaker itself is average in terms of volume, but very pleasant.

The dimensions of the phone are 135.4 x 66.2 x 7.9 mm and the weight is 138 grams. Compact, very small. It can drown in a man's hand, but someone likes this size. In clothes it is completely invisible, you can easily forget that there is a phone in your pocket, so it does not feel like a constant burden. If you like compact models, then you will definitely fall in love with the 2017 A3.

Compared to Galaxy A5 2017

Display

The younger model has a screen with HD-resolution, on such a diagonal low resolution does not play a big role, the picture looks good. But for those who like to peer at the screen and distinguish PenTile, I will not recommend this screen, you will see its structure from a distance of ten centimeters, from five centimeters you can accurately determine the "looseness" of the picture. It is clear that no one is looking at the screen so close, but who cares? Ordinary people, not burdened with knowledge about PenTile, will simply say that this is a good screen that produces a pleasant picture, which is also customizable.

Specifications This SuperAMOLED display is as follows: 4.7 inches, SuperAMOLED, HD, 312 ppi, auto dimming, auto dimming to suit your habits, color profiles, Corning Gorilla Glass 4, AlwaysOn Display.

For my taste, the quality of the screen is excellent for its class, it has a large margin of brightness in automatic mode, the display is readable in the sun, as well as in the model of the previous year (in the S7 EDGE the screen has a higher brightness, as a result, in the sun it is even better) ...

The screen has the AlwaysOn Display option, that is, you can see application icons, clocks or pictures all the time, the screen does not drain the battery much, for 12 hours it is a couple of percent. Until now, this function has not been massively in the middle price segment, which noticeably distinguishes the A3 2017 and puts it on a par with Samsung's flagships.

Whatever one may say, the screen in this model is excellent for its positioning and capabilities, and you don't need more. Taking into account the scenarios of using the device (a minimum of heavy games with complex graphics as an example), this is the right choice.

Battery

The built-in Li-Ion battery has a capacity of 2350 mAh, fast charging is not supported, but the standard charger charges the battery in 1 hour 35 minutes. That is, there is no need for fast charging, due to the small capacity of the battery, the charging time is normal. The built-in wireless charging that flagship models have is not here.

In mixed mode, the device lives quietly for two days with 3-4 hours of screen operation, data transfer in LTE and two hours of calls. It all depends on what and how you use, you can achieve better results, for example, 5-8 hours of screen work in two days of work, as well as less time.

Play unconverted HD video in MX Player at maximum brightness - up to 17 hours. This is an excellent figure considering the size of the battery, many Chinese people show comparable results with a 5000 mAh battery.

The operating time of the A3 2017 becomes its strong point, even with a heavy load, it will not be possible to discharge it faster than in a day, on average it is two days. Those who use only calls can safely count on 5-6 days of work, of course, it all depends on the operator and the number of these calls. But in general, we can state the fact that the operating time is the strong point of this model.

Traditionally, there is a power saving mode, when the backlight of the screen, the frequency of the processor are limited, in this mode many will not experience problems with the operation of the device, but the operating time will increase by at least 20 percent. In the maximum power saving mode, everything on the screen is colored in gray colors, and the device can provide hours of operation even with a small charge.

Communication capabilities

The work of GPS / GLONASS is excellently implemented, a cold start takes about ten seconds, navigation works well, there are no problems. By the way, this distinguishes A-brands from many Chinese companies, where the implementation of antennas is such that you can expect anything from typical functions.

Another strong point is the support of almost all the necessary LTE frequencies, here the device also manifests itself with strong side(analogs in this price segment cannot boast of this, as a rule, there are savings on antennas).

Finally, the device has NFC, ANT + support, which will appeal to those who use sports sensors. Bluetooth version 4.2.

If we talk about Wi-Fi, then 802.11 a / b / g / n / ac 2.4 + 5GHz is used here, there is a repeater mode (distribution of a Wi-Fi signal to other devices as an access point).

The version is USB 2.0, but the USB Type C (1.0) connector is used, so lovers of modern connectors will be happy, the rest should come to terms with the transition to the new standard.

Memory, RAM, performance

Samsung uses its own chipsets in the A-series models, which can be considered a plus, they are improving year by year. For example, in 2016 the chipsets in the A-series were made at 28 nm, now it is 14 nm, which gives an increase in performance and operating time. Chipset in A3 2017 Exynos 7780, 8 cores up to 1.6 GHz (Cortex A53), GPU Mali-T830.

This processor performed well in synthetic tests. In real life, everything also works perfectly well, you will not feel any shortcomings in performance, the model is on a level, and the safety margin will last for a couple of years at least.

The built-in memory in the device is 16 GB (9.7 GB is available), memory cards can be up to 256 GB. RAM 2 GB, which is enough for most consumers for the eyes. And considering the screen resolution, everything becomes quite good, this solution is balanced, and there are no noticeable compromises here.

Camera

The front camera is 8 megapixels (f / 1.9), as usual, there is no autofocus, so it is worth finding the distance from which the pictures are best taken, this is about half a meter, that is, an outstretched arm. The quality of the front camera is good, but don't expect anything special from it, the main camera is still better. There is a traditional improvement in skin color and tone, you can enlarge your eyes, and at the same time make your face thinner. The girls will definitely like these “uluchshaki”.

The main camera is 13-megapixel (f / 1.9), of course, there is autofocus, as well additional modes shooting, including PRO, but it differs from the flagships, since the camera is simpler. The camera on the A3 is simpler than on the older models, don't expect much from it. But she copes with her work quite well: taking pictures of pages with text, capturing the world around her - all this can be done. But if you want to shoot beautifully for social networks, then look at the flagships or models above the class.

When recording video, the maximum is FullHD resolution and 30 frames per second.

Look at the examples of pictures and videos, I think they will tell you all about the quality of the camera.

Software

The model originally came out on Android 6.0.1, but many of the interface elements are similar to what we see in Android 7 and Clean UI on the S7 / S7 EDGE. I advise you to read about what has appeared in Android 7, as soon this model will receive this version OS.

Describe standard Android functions I will not, you can read about them in a detailed review.

Unlike the top models, there is a built-in FM radio here, which looks like a nice bonus.

When using KNOX, you can install any program in duplicate, for example, install two WhatsApp messengers on one device and use them for each SIM card (two numbers, two messengers). You can even correspond with yourself. Exactly the same trick can be done with any software, no phone allows you to simultaneously work with two messengers on one device with different numbers... Today many Chinese manufacturers offer something similar in their smartphones, but the implementation is different everywhere.

Impressions

The vibration alert is average, the ring volume is also average - perhaps, I would like to have more headroom, but you can still hear the phone and feel it in your pockets when vibrating. Rather, there is no volume reserve, but here who will perceive this moment, the device cannot be called quiet.

There are practically no compact models on the market, keep in mind that Samsung has always been able to make its devices smaller than the competitors, just remember that 5.2 inches from Samsung is the body of many 4.7-4.9 inch models. So here, the A3 2017 turned out to be very compact, only one competitor immediately comes to mind - the iPhone SE. But the price of this compact phone is noticeably higher with similar characteristics and 16 GB of memory, in Russia it costs 31,990 rubles. In terms of design, this is the complete opposite of the 2017 Galaxy A3. Plus the iPhone SE is a camera, but there is no water protection, of course, there is no AlwaysOn Display, the battery life is the same or less.

Also made in a completely different style Sony Xperia X Compact, the model is small, but extremely expensive (32-33 thousand rubles). Comparable battery life, slightly faster processor, better camera, no water protection and no AlwaysOn Display. This model certainly does not have any special advantage over the A3, which would have cost 10,000 rubles. In terms of price positioning, it is close to the iPhone SE.

While there were many competitors in the segment of 5-inch models for the 2017 A5, there are practically no competitors for compact 4.7-inch models and with small bodies. The two main competitors are the iPhone SE and the Sony Xperia X Compact, but they cost significantly more. Sony will release an updated version of this smartphone, but the price difference will be even greater. Only big companies can afford to play on the market of compact models, and, unlike Samsung, they see such devices as models with super-profits. In my opinion, this is the wrong approach, since a compact, material-worthy smartphone cannot cost prohibitively expensive, as the A3 of 2017 proves. For those looking for a compact Android model, this particular device will be the preferred choice.

Comparison with the 2017 A5 may take place, but here you get a larger case size, higher performance, higher screen resolution and approximately the same operating time in the older model. But you lose that very compactness. These are different worlds in terms of perception based on the size of the case, and this must be taken into account, everything else fades into the background.

The model of the previous season, namely A3 2016, is weaker in every sense: shorter operating time in any of the modes, the absence of an AlwaysON screen and protection from water, and there is no support for Samsung Pay. On the other hand, if you have such a phone and it works, then you shouldn't change it to a new one. Wait another generation and then change. However, buying it now as a compact phone is worth it if there is no money for new model(the previous one costs 17,990 rubles). Let me remind you that the price of the A3 2017 is 22,990 rubles.

Bottom line: The 2017 A3 is great for those looking for compact smartphone, the emphasis will be on calls, instant messengers, web browsing, and to a lesser extent on heavy games. As a second smartphone, this device is ideal, as it works for a long time and is compact. The model turned out to be successful, but compact phones remain in demand by a not very wide audience, so it's not worth reading the A3 2017, it plays only within the niche of compact devices.
