Samsung has introduced its fans a compact, productive and stylish gadget - samsung galaxy A3. As expected, this model has both undeniable advantages and not entirely clear shortcomings. But first things first.

Design

No matter what anyone says, there is a certain similarity between the design and the iPhone. This is especially noticeable on the edging of the case. The phone has rather small dimensions with a display diagonal of 4.5”. In the palm lies well and securely. Although for a small female hand it can still be too big.

All mechanical buttons are exactly where they should be. The volume is on the left side, the power button is on the right. And, as always with Samsung, the home button is located on the front of the case. It is really convenient to control the phone.

On the back cover, everything is simple and concise - a slightly protruding camera, an LED flash and a speaker. There are no more hardware elements. The overall conciseness of the design is more of a plus than a minus. phone fit both for connoisseurs of rigor in execution, and for those who want something extraordinary. We offer you several color solutions.

Performance

Smartphone running operating system Android systems 4.4.4 KitKat. Thanks to the powerful Qualcomm Snapdragon 410 MSM8916 quad-core processor with a clock frequency of 1.2 GHz, the phone copes with all tasks perfectly. No interface slowdowns were noticed, applications run quickly and smoothly, and games also run without problems.

Random access memory here is 1 gigabyte. In principle, it is enough, although in the future this may not be enough.

16 gigabytes of internal memory, which is more than enough for the average user modern smartphone. And if this is not enough for you, the memory can always be expanded using a microSD memory card (up to 64 GB).

Among the minuses is not enough capacious battery. 1900 mAh is the average today. Nothing special, but during the day with active loads, the phone can work without recharging. And if you use it only for calls and SMS, then the charge will be enough for you without problems for two days.

Functional

The screen is made using Super AMOLED technology, which provides it with excellent color reproduction and wide viewing angles. Although we will not deny that the resolution of 540x960 has not surprised anyone for a long time. However, the sensor is responsive and the picture is nice. More is not needed.

Samsung Galaxy A3 has two really good cameras - the main one is 8 megapixels with LED flash, the second one is 5 megapixels (front). Both give an excellent picture, which is not surprising, because the cameras have been one of the strengths of Samsung for several years now.

Regarding the speaker, you can not call it super loud, although you are unlikely to miss a call even on the street. The volume is quite enough, and the sound of the speaker is clear and pleasant. There are no special claims here. Headphone sound is also good. For music lovers, the Samsung Galaxy A3 is a great option.

Also, the pluses should immediately include the presence of slots for two SIM cards. Today, single-symbol phones are becoming more and more history. Samsung is well aware of this. Suitable smartphone both for business people who need to always stay in touch, and for ordinary users who use one SIM card for calls and SMS, and the second one for accessing the Internet. Management and switching between SIM cards is convenient and intuitive.

In general, the phone turned out really good. It is stylish, efficient and easy to use. On the other hand, there is not enough capacious battery, a clear “zakat” under the iPhone and less RAM than we would like. Yes, and the price still bites.

Ruler Galaxy smartphones A has undergone major changes in 2017, which undoubtedly benefited. The manufacturer has changed not only the characteristics, but also the case materials. If until recently glass and metal were used exclusively in flagship solutions, now they are increasingly found in the middle and even budget price category. Let's review the Samsung Galaxy A3 black 2017 to see how good this smartphone is and whether it justifies its price.

Samsung Galaxy A3 2017 design

The design completely repeats the outlines of the Galaxy S6 and differs for the better from the Galaxy A3 2015. This is due to improved quality and premium case materials. The back and front panels are covered with 2.5D Gorilla Glass 4 glass, on the surface of which a high-quality oleophobic coating is applied. In general, the device is rather slippery, which is a characteristic drawback of all glass panels. Almost no prints remain. The metal case has a rounded shape, but the side ends are left flat so that the device does not slip out of the hands.

The Samsung Galaxy A3 smartphone review in Russian was carried out on the black version, but upon purchase you will have a good choice of colors: gold, white and pink.

Control keys and functional elements are arranged in a style familiar to the manufacturer.

Above the screen are sensors, a spoken speaker and cameras.

Below it is the hardware Home key (there is no fingerprint scanner in the younger model of 2017), as well as on the touch key to the left and right of it.

On the left side are the volume keys.

On the right is the power button and a tray for two nanoSIMs. Instead of a second SIM card, you can install a flash drive if the built-in volume is not enough for you.

On top there is a mesh for a noise-canceling microphone.

At the bottom of the case there is a 3.5 mm headphone jack, a speaker, a microphone hole, and a MicroUSB port.

Samsung Galaxy A3 sm a300f gold review showed that there is only a camera module and a flash to it at the back.

The build quality does not cause the slightest doubt, and you should not expect anything else from the Korean manufacturer, which has been a leader in the global electronics market for several years now. The mechanical keys have a pleasant travel. Rounded edges and minimal bezels around the display have a positive effect on the ergonomics of the case. It is convenient to work with a smartphone even with one hand. The changes are especially noticeable if we draw an analogy with the Galaxy A3 15-16 years. One of the main changes is the use of better materials and screen upgrades.

Display Samsung Galaxy A3 2017

Samsung Galaxy A3 2017 review showed that the model was equipped with a compact 4.7-inch display with HD resolution and a pixel density of 312 ppi. On the one hand, the pixel density is quite high, but do not forget about the features of AMOLED panels, which have a specific pixel structure. In this regard, their density can be divided by 1.5. It turns out 208 ppi, which is more like the truth. Samsung Galaxy A3 2017 a320f sm review revealed the weaknesses of the matrix. The diagonal grid is visible to the naked eye, the fonts are loose and the red tint predominates.

As is typical for AMOLED panels, the colors here are very saturated, and there is enough brightness to spare. Reading in the dark does not tire the eyes, especially with an active blue filter. Viewing angles are great, but even with small deviations, insignificant color inversions are observed. In general, the review of the Samsung Galaxy A3 2017 sm a320f smartphone showed that when the tilt is increased, they remain unchanged, so this drawback is quite forgivable. The black tint is very deep, and the white comes out a bit muddy. The settings provide four scenarios for the screen: “movie”, “photo”, “adaptive”, “standard”. If it is comfortable to work in all modes in the manufacturer’s flagships, then only “adaptive” will fit due to the low resolution. Others produce overly dirty whites.

Conducting a smartphone Samsung sm a310f Galaxy A3 review, we checked the operation of the light sensor. Automatic setting brightness does its job well, adjusting to changes in lighting conditions.

The screen deserves a good rating. There are gorgeous viewing angles, and the temperature regime characteristic of AMOLED matrices, as well as a solid oleophobic coating. The display behaves well in the sun. Colors do not fade and information is easy to read.

Samsung Galaxy A3 2017 performance

Characteristics Samsung phone Galaxy A3 is based on an 8-core chip with a frequency of 1.6 GHz. Officially, the manufacturer does not provide details about its processor, but no one can hide from AIDA64 - Samsung Exynos 7 Octa 7870 is installed. It is built on a 14 nm process technology, and Mali-T830 is responsible for the graphics. Built-in memory is 16 GB, but less than half of this amount is available for use - only 6.5 GB. Samsung Galaxy A3 lte 2017 specifications are complemented by 1.5 GB of RAM, which is definitely not enough in 2017. And after clearing the memory, only 0.9 GB is available.

In games, the smartphone showed itself differently, which is most likely due to optimization. So, in Asphalt Extreme everything flies at maximum graphics, and in Unkilled there are brakes even at medium settings. With simpler games, the model copes with a bang. There is a screen recording function, but when it is turned on, even the simplest processes begin to fail.

Samsung Galaxy A3 sm a300f gold duos review showed that even at high loads, throttling does not make itself felt, and the temperature rises only slightly.

autonomy

Samsung a300h Galaxy A3 2017 duos battery performance is one of the strengths. No matter how paradoxical it may sound, but the capacity of 2350 mAh is enough here. It has everything you need for really good autonomy: a low-resolution AMOLED matrix, an energy-efficient processor and excellent system optimization.

When playing video at the highest brightness with all active wireless communications, the smartphone lasted 17 hours. Even models with twice the battery capacity cannot boast of this. For an hour of playing Asphalt Extreme, the smartphone loses only 11% of its charge. In everyday use, it lasted two days with 5.5 hours of display operation. A review of the Samsung Galaxy A3 phone showed that if you use it less actively and turn on proprietary power saving, then it will last much longer.

Interface

Samsung Galaxy A3 sm a300f white review in Russian goes to the interface. It uses the proprietary TouchWiz Nature UX 5.0 shell, built on Android 5.1.1. We are familiar with it from other models of the manufacturer.

The lock screen displays a clock, weather widget and missed notifications. You can set up a quick transition to the contact book or launch the camera.

Preinstalled task manager smart manager allows you to track the main indicators of the device (the amount of RAM, battery consumption, as well as the amount of free memory and much more).

The Home button has additional functionality - the ability to launch the camera with a double tap when the display is locked and the function of answering a call.

Cameras Samsung Galaxy A3 2017

Samsung Galaxy A3 review of the camera, we will start with its characteristics - a resolution of 13 megapixels and 5 megapixels in the case of a front camera. Each module has an aperture of f/1.9, but optical stabilization absent (in A5 and A7 it is). Video is shot in Full HD at 30 frames per second. The camera interface is very simple, it will not be difficult to figure it out even for an outstanding user. There are all basic shooting modes and effects.
Samsung Galaxy A3 sm a300f camera review showed that the pictures lack sharpness when viewed on a computer, while everything looks fine on the phone's display. Photo quality can be described as average.

Conclusion

Smartphone Samsung Galaxy A3 characteristics price reviews make it a good offer in the middle price category.

Advantages:

• Compact body with premium materials;
• High-quality display and oleophobic coating;
• Phenomenal autonomy.

Flaws:

• The lack of a fingerprint scanner, which has become the main trend of recent years;
• No optical stabilization;
• I would like to see a light indicator of events, which is not here.

Samsung sm a320f Galaxy A3 review showed that we are offered a compact and ergonomic body, which also looks stylish. In addition, there are balanced characteristics, good screen and cameras. But the smartphone would be even better if it had a fingerprint scanner and optical stabilization. Although this is another story, because they are in older versions.

Your assessment of the smartphone:

The Korean company Samsung adheres to its well-thought-out trend and releases new versions of its A-series smartphones every year. The names remain the same, only the year of issue changes.

The exact release date of the Samsung Galaxy A3 is October 31, 2014. Is it really good and is it worth buying, based on the realities of today? Galaxy overview A3 will answer this question.

Completion and packaging

The device came to the market in a beautiful blue cardboard box. The front panel contains capital letter And, and below - the full name of the smartphone. At the bottom of the box, the manufacturer printed a description of all the specifications of the Samsung Galaxy A3 (2015). Package components:

• Charger;
• microUSB cable;
• clip for a tray for two Nano-SIM-cards;
• headset with microphone;
• instructions with a warranty card (warranty is valid when purchased from an official Samsung store or a dealer store).

There are many color schemes of the device on the market (in Samsung, even non-flagship devices are always brightly and juicy). The Galaxy A3 is available in white, blue, navy blue, gold, pink and magenta.

Video

Appearance and design

The front panel is painted to match the main body color of the device. The sides have a metallic sheen. This can be seen in the photo below:

metal side panels Samsung Galaxy A3

In the center of the back panel is the main camera, LED flash, perforation area for the main multimedia speaker and the logo of the Korean manufacturer. The front camera, sensors, two touch buttons with backlight and the main mechanical button, which performs the function of returning to the main desktop of the Galaxy A3.

The top end is equipped with a small hole for an additional microphone of the noise reduction system, and the bottom edge contains a metal headphone jack, a microUSB charging slot and a hole for the main conversational microphone. On the left side are the volume keys, and on the right are two trays and a power button.

The top end of the smartphone

The decision of the Samsung developers about the trays is not clear. In one, you can install a Nano-SIM card, and in the second, either a SIM card of the same format or a MicroSD memory card. It would be more practical to provide an opportunity to install a memory card in one tray, and a SIM card in the second one.

Overall, the design of the Samsung Galaxy A3 (2015) is good. The disadvantages include the main camera lens protruding slightly above the body and an unnecessary serial number at the bottom of the rear panel.

Despite the fact that the body is completely metal, the smartphone is light and weighs 110 grams. It is convenient for them to use with one hand, it is not slippery and not easily soiled - the device does not have to be hidden in immediately after purchase. The size samsung cases Galaxy A3 (2015) is 130.1x65.6x6.9mm. This is a really compact device. The assembly of the gadget is excellent: even with strong pressure on the body and ends, no squeaks or backlashes are heard.

Lightweight clean smartphone design

Display

The front panel of the device from Samsung has a small display with a diagonal of 4.5 inches. Its resolution is qHD (not to be confused with QHD) or 540x960 pixels. With a dot density of 245 ppi, the screen does not grain, "burnt" pixels are not visible. Illuminated elements were also not found. The screen is made by technology. But the display can be attributed to the minuses, because for $ 250 at the end of 2014, I would like to get at least an HD matrix.

4.5" Super AMOLED display

Viewing angles are excellent, there are no complaints about them. Maximum brightness allows you to see the picture in conditions of intense lighting, be it studio or sunlight. Minimum brightness is also ok.

A3 touch screen supports multi-touch

Will be useful

The Korean manufacturer in the Galaxy A3 has preset display color settings, since AMOLED panels, as a rule, have increased saturation of green, blue and red colors (somewhere there is an overweight of one of them). Therefore, the modes help to improve color reproduction and not disturb the user's vision.

The glass reflects glare and provides protection from dirt, thanks to the applied layer of oleophobic coating.

Software

Samsung Galaxy A3 (2015) runs on Android 4.4.4 KitKat operating system. The manufacturer periodically releases updates for it. The company has preinstalled its latest version of Samsung TouchWiz software. It is also found on flagship Samsung devices Galaxy S4 and Samsung Galaxy S5.

Of the chips of the system, it is worth noting the presence of a built-in FM-radio module (it functions only with a connected headset or other headphones without a microphone). The radio works adequately and provides good reception of stations.

Of the shortcomings of this device, it is worth noting the lack of a heart rate sensor, and, accordingly, the S Health program. If in the flagships the functionality of the system was wider, then The Samsung Galaxy A3 (2015) does not have the Kids Mode app and other useful and interesting features.

note

There is great amount themes that can be downloaded from the dedicated store. They change not only the wallpaper and some other elements, but also the icons and the entire interface.

The shell works quickly. It is one of the most stable and popular systems not only in Samsung, but in the entire mobile market.

Sound

The main multimedia speaker is located on the rear panel of the device. In this regard, the protruding lens of the main camera allows you to slightly raise the device above the table, which ensures efficient operation of the speaker: the sound from the main speaker is not muffled or distorted. This allows not only not to miss an important call, but also to listen to music with comfort.

Speaker and microphone

There are both low and high frequencies. The volume reserve is sufficient. The main point is the purity of sound. At maximum volume, it does not "wheeze" and is not distorted. The speaker can be attributed to the merits of the "middling". The sound in the headphones is almost the same quality, but the bundled one is not the best.

The earpiece is also loud and clear. Does not "wheeze" during a long conversation. Thanks to the additional microphone of the noise reduction system, the interlocutor hears you without interference or unnecessary background sounds.

Performance

It is worth reading the description of the characteristics of the hardware component of the Samsung Galaxy A3 (2015). The Qualcomm Snapdragon 410 or MSM8216 quad-core single-chip platform is responsible for performance. Four cores of the Cortex-A53 type operate at a frequency of 1.2 GHz. Responsible for graphics Qualcomm processor Adreno 306. Even for the beginning of 2015, hardware is the most budget-friendly on the market. Other devices already had a Snapdragon 600-series chipset on board, but the company apparently decided to save on this moment.

Built-in storage and RAM sizes are 16 GB and 1 GB- also not the best indicator. Given that about 11 gigabytes are available, and the memory card is installed in the combo slot, the amount of ROM is a minus. On 16 GB of internal storage, you can install several dozen applications, several games, but there is not enough space for music. 1 GB of RAM is also "not serious", because modern applications can take 75% of the total.

Since the hardware is budgetary, in Antutu software Benchmark it scores 21484 points. This means that "heavy" games can be played on low graphics at 25-30 frames per second. If you switch to the lowest Presets, then the figure will be 35-42 FPS. The low performance in Antutu is also due to the fact that the potential of the processor is not fully revealed due to the presence of the Android 4.4.4 operating system, which does not “understand” 64-bit crystals.

Benchmark version 5.6.1

All networks work without any problems. There is support for NFC, and Wi-Fi, which can operate in the 2.4 GHz band. Embedded module LTE is capable of downloading data at a maximum speed of 150 Mbps, and the 3G module at 42.2 Mbps. Mobile communication and navigation system work without interference even indoors.

Camera

The main camera shoots at a resolution of 8 megapixels. Front - 5 MP. Pictures in good lighting conditions are of high quality, without various artifacts and noise. Autofocus is fast, and the dual flash allows you to take clear pictures at night.

Mobile networks

A mobile network is a radio system that allows multiple mobile devices to communicate with each other.

GSM GSM (Global System for Mobile Communications) is designed to replace the analogue mobile network (1G). For this reason, GSM is often referred to as a 2G mobile network. It is enhanced by the addition of GPRS (General Packet Radio Services) and later EDGE (Enhanced Data rates for GSM Evolution) technologies.	GSM 850 MHz GSM 900 MHz GSM 1800 MHz GSM 1900 MHz
TD-SCDMA TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is a 3G standard for mobile networks. It is also called UTRA/UMTS-TDD LCR. It is developed as an alternative to the W-CDMA standard in China by the China Academy of Telecommunication Technology, Datang Telecom and Siemens. TD-SCDMA combines TDMA and CDMA.	TD-SCDMA 1880-1920 MHz TD-SCDMA 2010-2025 MHz
UMTS UMTS is short for Universal Mobile Telecommunications System. It is based on the GSM standard and belongs to 3G mobile networks. Developed by 3GPP and its biggest advantage is to provide more speed and spectral efficiency with W-CDMA technology.	UMTS 850 MHz UMTS 900 MHz UMTS 1900 MHz UMTS 2100 MHz
LTE LTE (Long Term Evolution) is defined as a technology fourth generation(4G). It is developed by 3GPP based on GSM/EDGE and UMTS/HSPA to increase the capacity and speed of wireless mobile networks. The subsequent development of technologies is called LTE Advanced.

Positioning

Most 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 - this is Apple ( iPhone model SE), Sony (Compact series), and Samsung. In A3 2017, the desire of some buyers to get a small, compact phone is just realized. A relatively small screen diagonal of 4.7 inches determines the scenarios for using such a device - first of all, it is needed for calls, 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 perfect - it works for a long time, has a balanced, modern set of functions. But it is also good as a main device for those who are not looking for a large screen diagonal and are used to compact models.

On the side of this model, a set of functions comparable to older devices, although in A3 2017 a number of features were removed compared to A5 / A7 - the front and main cameras are simpler in the phone, the screen resolution is lower (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 samsung Pay (NFC/MST), IP68 water protection remains. As well as the use of exactly the same materials, which distinguishes the model from many classmates, it is perfectly executed. 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 noticeable, the impressions from them are very different. Moreover, these differences are both positive and negative, and depend directly on what you are used to.

Design, dimensions, controls

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

I have a black A3, it is classic and looks good. The mirror surface reflects the surrounding world, plays in the light, the device looks very interesting, and handprints are almost invisible. I will add here that the screen with a splash screen (AlwaysOn Display function) can always work, 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 a 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 the same color, as is the side metal piping (6000 series aluminium). In pink, the device also looks good, but it is definitely only for girls.

The golden phone is somewhat rustic, but everyone has their own tastes.

The fact that the device has a glass back and front 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 at the level. I once recorded a video about how this phone survives a collision with sharp objects or asphalt, you can watch this video.

The innovation of the A-series in 2017 was the water protection, 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 speaker are covered with membranes, the protection level is IP68, which allows the phone to be at a depth of up to 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, nothing will happen to it. In that price segment There are no waterproof models.

Now about controls. Under the screen there is a mechanical key, it contains a fingerprint sensor, it is simplified compared to the 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 are two touch keys.

On the left side there are two volume keys, on the right side there is an on/off button. There is a noise reduction system on the lower and upper ends - on the microphone, it does its job perfectly, you can be heard well in any conditions, even when the wind is blowing hard in 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 end there is a tray, a nanoSIM card and a memory card or two SIM cards are installed in it. This is a combo tray, so it's worth remembering, A5 / A7 can install both a memory card and two SIM cards at the same time.

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

Phone dimensions - 135.4 x 66.2 x 7.9 mm, weight - 138 grams. Compact, very small. It can sink in a man's hand, but someone likes this size. It is completely invisible in clothes, 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

In the younger model, a screen with HD resolution was installed; on such a diagonal, low resolution does not play a big role, the picture looks good. But for those who like to peer into the screen and distinguish PenTile, I will not recommend this screen, you will see its structure from a distance of ten centimeters, and from five centimeters you can accurately determine the “looseness” of the picture. It is clear that no one looks 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 nice picture, which, moreover, is customizable.

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

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

The screen has an 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 feature has not been massively available in the middle price segment, which noticeably distinguishes the 2017 A3 and puts it on a par with Samsung flagships.

Whatever one may say, the screen in this model is excellent for its positioning and capabilities, you don't need more. Given 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 a regular 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. Embedded wireless charging, which 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 and best results, for example, 5-8 hours of screen time in two days of work, as well as less time.

Playing unconverted video in HD quality in MX Player at maximum brightness - up to 17 hours. This is an excellent indicator given the size of the battery, many Chinese show a comparable result on a 5000 mAh battery.

The operating time of the A3 2017 becomes its strength, even with a heavy load it will not work to discharge it faster than in a day, on average it is two days. Those who use only calls can easily 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 a strong point of this model.

Traditionally, there is a power-saving mode, when the screen backlight, processor frequency 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 painted in gray colors, and the device, even with a small charge, can provide hours of operation.

Communication options

The work of GPS/GLONASS is excellent, a cold start takes about ten seconds, navigation works perfectly, 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 strength is the support for almost all necessary LTE frequencies, here the device also manifests itself with forte(analogues 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 + 5 GHz 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 fans of modern connectors will be happy, it's time for the rest to 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 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), Mali-T830 GPU.

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

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

Camera

The front camera is 8 megapixels (f / 1.9), as usual, there is no autofocus, so it's worth finding the distance from which the pictures are best taken, which is about half a meter, that is, an outstretched arm. Quality front camera good, but do not expect anything special from it, after all, the main camera is 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 “improvements”.

The main camera is 13-megapixel (f / 1.9), of course, there is autofocus, as well as 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 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 all tell you about the quality of the camera.

Software

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

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

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

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

Impression

The vibrating alert is average, the volume of the ringer is also average - perhaps we would like to have more headroom, but the phone is still audible, and it is felt in pockets when vibrating. Rather, there is no reserve in terms of volume, but then whoever perceives 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 its competitors, just remember that 5.2 inches from Samsung is the body of many 4.7-4.9 inch models. So here, the A3 of 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 much higher with similar characteristics and 16 GB of memory, in Russia it costs 31,990 rubles. Design-wise, it's the exact opposite of the 2017 Galaxy A3. Plus, the iPhone SE is a camera, but there is no water protection, there is, of course, AlwaysOn Display, the operating time is the same or less.

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

If there were many competitors in the segment of 5-inch models for the 2017 A5, then there are practically no competitors for compact models of 4.7 inches and with small cases. The two main competitors are the iPhone SE and the Sony Xperia X Compact, but they cost significantly more. Sony will release updated version this smartphone, but the price difference will be even greater. Only large companies can afford to play in 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, decent smartphone cannot be prohibitively expensive, which proves the 2017 A3. For those who are looking for a compact model on Android, this device will be the preferred choice.

Comparisons with the 2017 A5 may be true, but here you get a larger body size, higher performance, higher screen resolution and about the same battery life in the older model. But you lose that very compactness. it different worlds according to 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 the 2016 A3, is weaker in every sense: less battery life in any of the modes, lack of an AlwaysON screen and water protection, and no support for Samsung Pay. On the other hand, if you have such a phone and it works, then you should not change it for a new one. Wait another generation and then change. However, it is worth buying it now as a compact phone if there is no money for new model(the previous one costs 17,990 rubles). Let me remind you that the price of A3 2017 is 22,990 rubles.

Bottom line: A3 2017 is great for those who are looking for a compact smartphone, which will focus on calls, instant messengers, web browsing, 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 for some huge sales, it plays only within the niche of compact devices.
