Comparison with competitors Samsung Galaxy A3

If we take into account the smartphones on the market with a screen diagonal of 4.5-4.7 inches, then we will find a sufficient number of offers. Big-name manufacturers offer mostly mini-versions of flagships, while smaller brands try to lure buyers. technical specifications. Consider the most interesting options.

Among competitors, the no less fashionable HTC is immediately remembered. One mini 2 , which has already visited our laboratory. Though this device has been on the shelves for a long time, the price for it has practically not fallen since the moment of its release. The rest of the devices are very similar to each other, but the brainchild of HTC offers best screen, more megapixels in the camera and more metal in the body. Of the minuses - thickness and weight. And the performance is still not higher.

LG L90 also managed to "light up" on our site, and left a positive impression. It is in no way inferior to the hero of our review in terms of autonomy, but the quality of the screen and pictures on the camera leave much to be desired.

Since the prices of the Sony Xperia Z3 Compact have skyrocketed, we can no longer compare it with the Samsung Galaxy A3, so much more plays for the Japanese today. simple model– Sony Xperia E3 dual. In general, it cannot offer customers outstanding performance, but you will have to pay much less money for the “Japanese” than for competitors.

And if we take into account models with a screen diagonal of 4.3 inches, then Sony is ready to defend the honor Sony smartphone Xperia Z1 Compact, which can still be bought from the "gray" supply for a comparable amount to what is asked for the Samsung Galaxy A3. Of course, this device bypasses all competitors in terms of technical characteristics, but in terms of autonomy it is inferior to energy-efficient chips, and even after reducing the hype around Galaxy line And it can hardly be compared with the Samsung Galaxy A3, because the price of this device will not fall much.

When the manufacturer's assortment grows so much that it becomes almost impossible to memorize it, there is a high probability of "cannibalization". The positions of the Samsung Galaxy A3 are threatened by the Samsung Galaxy S5 duos, which has no restrictions on the use of SIM cards and memory cards, and at the same time, a larger capacity removable battery and an HD screen are in the pluses. Yes, it looks and feels not as expensive as any of the representatives of the Galaxy A line, but if “image” is an empty phrase for you, then there is no point in choosing the Samsung Galaxy A3.

Of course, one cannot but recall the Samsung Galaxy Alpha. Now you can buy it in a "gray" version for almost the same amount that they ask for a "white" Samsung Galaxy A3, but you get a "lightning" device in the same quality and stylish case, although there are some compromises in this smartphone. No wonder it was discontinued.

Since we are talking about a 4.7-inch diagonal, it would be a sin not to remember the HTC One M7, which can now be bought in some stores at a comparable price, while you get a full-fledged flagship of the manufacturer, albeit not the first freshness.

Manufacturers from China are ready to offer quite productive solutions in this segment as well. For example, Jiayu G5S, which hides an eight-core MT6592 processor and two gigabytes random access memory. Of course, this is not the fastest single-chip system, but it is still faster than the Snapdragon 400/410, and the price will pleasantly surprise you.

Sadly, Lenovo can't offer something competitive in this segment, and ASUS is still stuck with the old dual-core Intel Atoms.

Conclusion

As a result, quite a lot of questions arise for the Samsung Galaxy A3. The first and most important of them is why it was impossible to make an uncompromising version of a fashion smartphone in this segment? Why is the user forced to choose between a second SIM card and a memory card? I understand that this is most likely due to the peculiarities of the internal layout, but it worked before. Upsets the screen resolution. Yes, the diagonal is not large, but even for 4.5 "I want to see at least HD (1280 x 720 pixels). And at the same time, with the advent of metal in the design, there was no room left for either moisture protection or stereo speakers.

It turns out that the Galaxy A3 has lost most of what Samsung smartphones loved for. It was practicality and manufacturability that compensated for the not very attractive appearance and inexpensive materials of the Korean giant's models. Yes, outwardly the novelty looks more advantageous than the same Samsung Galaxy S5 mini duos. But is it worth choosing premium materials instead of practicality and some technical characteristics? Here everyone decides for himself. Fortunately, we will soon consider more interesting technical terms senior solutions of the Galaxy A line.

Pros of Samsung Galaxy A3:

  • Premium materials, excellent build quality;
  • Pleasant weight and size indicators of the device;
  • Good battery life;
  • LTE support;
  • Not a bad camera;
  • Loud speaker;
  • Low heating;
  • Support second SIM or memory cards (optional).

Smartphone cons:

  • The inability to use two SIM cards with a memory card;
  • Low screen resolution;
  • Somewhat less practical than its predecessors.

May not suit:

  • Lack of LED-indicator of events;
  • Non-switchable dynamic contrast system;
  • Weak audio amplifier.

Stanislav Bobrov aka ARGUMENT_600



We are grateful to:

  • To the Russian representative office of Samsung for providing for testing Samsung smartphone Galaxy A3.

Due to the sharp change in the exchange rate, the issue of acquiring flagship smartphones of past years has become relevant.

In this comparison, we take a look at the updated flagship, scary to think, 2012 - and the representative of the new line - .

To begin with, we note that S3 NEO is two models at once: 9300i And 9301i they differ only in the number of slots for sim-cards - two and one, respectively. The Galaxy A3 (A300) also has a rather interesting solution regarding sim cards, it is simultaneously for one and two sim cards, but more on that later. Judging by megahertz and gigabytes, the S3 NEO is slightly ahead of the A300, but it is worth remembering that these are just numbers and a huge number of other parameters that are not written in the specification affect the real performance.

Frame

S3 is the same as in 2012: easily soiled glossy plastic in the form of a bar of soap or, as the manufacturer assures, coastal pebbles... However, like many Samsung devices, appetite comes with eating. The more you use your smartphone, the more you like its design.

If someone has not yet seen the Galaxy S3, then:

  • on the left side there are volume rockers


  • on the right - on / off / block button


  • bottom micro-usb connector and microphone

  • top - 3.5 headset jack

  • on the front part above the display is the front camera and light and proximity sensors

  • on the back is the main camera, LED flash and speaker

  • under the cover are located: a removable battery, a slot for a SIM card and a slot for a memory card


The A3 case doesn't look quite original either. The design of the smartphone strongly resembles the 2011 flagship Galaxy S2.


Although this is more a matter of taste, but in our opinion this is the right decision. Plus, a metal frame was added to the excellent design, which creates a feeling of a premium class device. The layout of buttons, cameras and sensors is similar to S3.


The only difference is the location of the 3.5 headphone jack.


The S3 has it on top, while the A300 has it on the bottom. In our opinion, the decision to make the connector at the bottom is more reasonable, but for most smartphones this connector is located at the top, so this will not be convenient for many users, because. you will have to get used to the new location of the connector, learn a special grip and an exclusive technique for putting the device in your pocket.

Also on the right side of the smartphone are two slots for SIM cards.


More precisely, one slot for nano-sim, and the second slot is universal (either nano-sim or a microSD memory card). The solution is a little strange, because many users want to have everything at once, but here you have to choose. However, the A300 supports 4G networks and given the development cloud services, the presence of a memory card is not so important.

The battery of the device is non-removable, and the back is made of metal with a matte finish.


In terms of the thickness of the case, both devices are quite compact and it makes no sense to measure hundredths of millimeters. A3 is more compact, but this is achieved due to the smaller diagonal of the display. So here to each his own. A funny detail in the design of the A3 is the rather protruding camera, which is most likely done so that the speaker does not close when lying on the table.

Verdict: In our opinion, the A300 wins in almost all respects.

Display

Samsung Galaxy S3 Neo has a 4.8-inch display with a resolution of 1280 × 720 pixels and a density of 305 pixels per inch.

Galaxy A3 has more modest parameters: display diagonal - 4.52 inches, resolution - 960 × 540 pixels, density - 245 pixels per inch.

But you should not believe the numbers, just put both devices side by side and it immediately becomes clear that the S3 grandfather, although he went to a sanatorium and rejuvenated a little, can in no way compete with the young A3.


Samsung Galaxy A3 looks much better: sharper, brighter, etc. Moreover, this can be seen both with the standard settings for automatic brightness control and when setting the maximum value manually.

Verdict: A clear win for A3

Performance

Samsung Galaxy S3 NEO has very good technical characteristics for its price segment. The system is powered by a 1.4 GHz quad-core processor and 1.5 GB of RAM. Galaxy A3 also has a quad-core processor, but clock frequency is only 1.2 GHz, and the RAM is 1 GB. However, we did not trust the numbers and tested the performance of the devices using the antutu benchmark.


Result: the performance of the old man, although a little, is still inferior to the new one - 20254 benchmark parrots against 20646.

Verdict: The A3 outperforms the S3 by a tiny bit, but still outperforms, so the A3 wins again.

Camera

The main camera of both devices has an 8 megapixel matrix, but we are already accustomed to not trusting the numbers, especially since everyone has long known happiness not in megapixels. If you look at the cameras from the display of the devices themselves, the camera of the A3 seems to be better, either because the display displays the picture more clearly, or because we first forgot to remove the film from the S3 camera ... after removing the film from the camera, according to personal impressions, the s3 camera is slightly -slightly inferior to a3, however, you need to look at the cameras from the finished pictures and here are examples of several photos:

On the left is a photo taken with the A3 camera, on the right - S3 NEO.
















It is immediately noticeable that... samsung camera The Galaxy A3 is almost indistinguishable from the Galaxy S3 Neo. The first photo was taken at close range in our office under standard lamp lighting. daylight, the second - with the lights off using the flash, the third shot - a general shot under standard lighting, the fourth - an enlarged fragment of the third. The fifth, sixth and seventh shots were taken outdoors during the day in cloudy weather, the eighth is an enlarged fragment of the seventh frame. In our opinion, the A3 shoots a little clearer, which is best seen in street shots.

It is also worth noting the capabilities of the front camera, because. the meaning of the word "selfie" is known even to pensioners and babies. So, for selfies, the Samsung Galaxy S3 can offer a 1.9 MP camera with pretty good quality, but nothing more interesting about front camera could not be found.

Galaxy A3 immediately pleases with the number - 5 megapixels, but as we have already seen, the number of megapixels is far from the most important parameter, so the first thing that catches your eye is the possibility of retouching, making the face thinner and the hit of the season, which amused us the most, eye enlargement.

Verdict: The A3's cameras are a bit ahead, mostly due to the front-facing camera.

Outcome

As expected, the novelty bypasses the old man in all respects, but there is one parameter that cannot be ignored - the price. Buy Samsung Galaxy S3 NEO at the beginning of April it is possible for only 11-12 thousand rubles, and Samsung Galaxy A3 cost is 16-17 thousand rubles.

In our opinion, the difference in price is quite justified, for the most part due to LTE (4G) and stylish design, but in the end, these parameters are not important for everyone, and whether it makes sense to pay more or not, everyone will decide for himself.
