Samsung galaxy core 2 duos description.

samsung galaxy Core 2 Duos SM-G355H has become the next model in the "galactic" line of the South Korean electronics giant. The smartphone, focused on the budget price niche, went on sale in June 2014. Now you can buy a device for about $ 100. What the buyer will receive for this money will help to find out our review.

Externally, the device is practically no different from its neighbors in the series. It is made in a rectangular case with rounded edges, metal edging and an oval-shaped home button. Behind, near the camera window, the flash LED and speaker are symmetrically located. Samsung Galaxy Core 2 Duos unveiled in black and white.

Specifications Samsung Galaxy Core 2 Duos SM-G355H

Technical samsung specifications Galaxy Core 2 Duos are quite common for an inexpensive device. But, at the same time, the processor of the device has four cores. In general, the filling of the smartphone is quite budgetary.

CPU

The use of processors from Spreadtrum for Samsung is nothing new. On the chips of this company, South Korean devices came out earlier. This time, the manufacturer used the SoC SC7735 platform, which is the closest analogue to the Taiwanese MT6582. The technical differences between these processors are minimal: both have 4 cores of the same architecture and a Mali 400 graphics processing unit. The difference lies in the CPU frequency (1200 MHz for our hero, versus 1300 for MT6582), and the number of GPU cores (2 for MTK versus 4 for Spreadtrum).

Thus, the Samsung Galaxy Core 2 Duos should slightly outperform its competitors in terms of performance (especially in games). But in reality, the difference is not felt either by eye or in benchmarks. And the same AnTuTu shows even a lower score (15 thousand versus 17-18 for MTK). It's good enough for games, but maximum settings graphics are not to be expected.

Memory

Where Samsung budget and mid-range smartphones can stand out is the amount of RAM. 768 MB random access memory almost never found in other manufacturers. There is only one answer to this: Samsung, in addition to smartphones and household appliances, is also engaged in the manufacture of memory chips. Since today they are no longer in use at 256 MB (in order to gain 1 GB of RAM, you need to solder as many as 4 chips on the board, and this is more complicated and more expensive than 1 by 1024 or 2 by 512 MB), the company equips inexpensive devices of its own with its products. production. And the user is happy (after all, he receives not 512, but 768 MB), and the "illiquid" product is sold.

As for the practical significance of "all these numbers" - here we can say that 768 megabytes is enough for the average user, but not enough for gamers and those who are used to "squeezing all the juice out of a smartphone." Against the background of cheap devices with 512 MB remaining on sale, it looks attractive, but for 2015 it is already not enough.

About half of the 4 GB flash drive is provided for storing user content in the smartphone. Fortunately, the disadvantage free space compensates for the presence of a microSD slot. Samsung Galaxy Core 2 Duos supports flash drives up to 64 GB.

Battery

A 2000 mAh battery for a "state employee" is normal. Moreover, the screen of the Samsung Galaxy Core 2 Duos is not so big. The battery charge will last for 2 days in standby mode, about 8-10 hours of video playback and/or web surfing, and about 5 hours of 3D gaming. For a $100 smartphone, that's not bad.

Camera

The Samsung Galaxy Core 2 does not deserve the title of a camera phone. 5 MP today is good for the front camera, but not the main module. However, the pictures are not so bad. On a winter day, there is almost no noise, however, as well as in a correctly “captured” summer landscape.

An example of a snapshot on the main samsung camera Galaxy Core 2

The room is a little worse, but not to say frankly bad. To be honest, we came across the "Chinese", which, even at 8 MP, showed disgusting quality. Therefore, we can safely assure you: for 5 MP, the Samsung Galaxy Core 2 duos camera good. Moreover, there is a flash, and it could not do without autofocus.

The front module has a resolution of 640x480 and is designed purely for video communication. Trying to take a selfie good quality it’s not worth it - it’s better to turn the smartphone with the back side and “blindly” shoot five frames, each time slightly tilting the device to the side to catch the face in the center of focus.

Display

The screen of the Samsung Galaxy Core 2 Duos is budgetary, and has a resolution of 800x480 pixels with a diagonal of 4.5". This is not a typical Samsung AMOLED, but a classic TFT TN, so you should not expect ideal viewing angles, as well as reduced power consumption with a certain color theme .

Connection

Under back cover The Samsung Galaxy Core 2 Duos hides two SIM card slots. They have the MicroSIM format, which is advantageous in terms of space saving. Because of this, owners of old-format chips will have to go to the operator for a replacement or cut them themselves.

Of the networks, GSM and UMTS/HSDPA standards are supported. In addition, you can maintain a high-speed connection only from the first "sim card": the second is intended for voice communication. These are the features of budget radio modules.

Multimedia

The sound of the Samsung Galaxy Core 2 Duos is truly "budget". He is loud, does not wheeze, but here frequency range let us down. It is much more pleasant to listen to music in headphones - there is at least a hint of bass. In fairness, it is worth noting that not only Samsung is guilty of this. So among its competitors, the Galaxy Core 2 Duos deserves a solid six (out of ten). And given that the smartphone also has a radio (unlike some flagships), there is no way to write down the multimedia side in the minuses.

Operating system

As operating system Samsung Galaxy Core 2 Duos is running Android 4.4. Naturally, it was not without the TouchWiz interface. The smartphone uses a stripped-down version of the shell, which is less functional than the flagships, but against the backdrop of a small amount of RAM, this is not a minus, but a plus.

    A terrible battery (well, or a controller in the phone) - even with the original one, it starts to suddenly lose charge after six months of use. With Chinese batteries, Ali is even worse.

    After several months, the charging socket became loose - it stopped charging with its native charger, picked up another cord, charged it for about a year, then did not charge a single cord at all. In the repair, the charging socket could not be replaced, because. the phone is disassembled "Through the face" - i.e. by removing the touchscreen and screen. The touchscreen began to fail - it opens and closes applications, throws it out and goes wherever it wants (not a virus for sure). Very little memory. All applications are automatically downloaded to the phone's memory and then do not always allow you to transfer them to the memory card. In general, there is often a problem when downloading and installing applications, some errors always come out. In general, a misunderstanding, not a phone.

    Memory. A total of 768 operational and 4 GB permanent, of which more than two are occupied by the operating system and Google services. There is a microSD slot, but nothing can be transferred from a smartphone without root to a memory card. As a result, memory is catastrophically small and not enough for anything. CPU. Not even Mediatek, but ultra-budget and weak Spreadtrum. GPS. I did not check, because there is no memory for cards. Pre-installed applications from Samsung, which (sic!) are not supported on this smartphone. Batteries are not enough for a day, even in energy-saving mode, the charge is melting right before our eyes. Shiny edging around the edges, which quickly peeled off.

Samsung has been pleasing the buyer with its mobile devices for several years now. In her model range There are devices of different classes: from budget to premium. As time has shown, gadgets with a price of up to 10,000 rubles are in high demand. Given their popularity, I would like to devote today's review to the Samsung Galaxy Core 2 Duos G 355H smartphone. It is an excellent representative of the segment of inexpensive phones. Buyers were pleasantly surprised to learn about the worthy functionality of this gadget. Of course, the flagship tasks are beyond his power, but for everyday use the device fits perfectly. According to the owners, the manufacturer was able to achieve the optimal ratio of cost and quality.

What are the characteristics and features of a smartphone? What technologies did the manufacturer use? The answers to these questions can be found in the article.

Delivery set and packaging

For the packaging box of the Korean phone Samsung Galaxy Core 2 Duos, a pattern of natural wood was used as the basis. Also, the designers were able to reproduce the naturalness of the shades of the color palette. In the left upper corner The front panel flaunts the company logo. Opposite it, there is information that the device works with two SIM cards. At the bottom of the front panel is the full name of the smartphone. On one side face there is a serial individual number of the device and information about the country in which the assembly was made. On the other, the main characteristics of the device are described in detail.

What is inside this box? The delivery set can be safely called standard. By the assortment of elements it is easy to understand that the phone belongs to the budget segment. Everything that will be available to the user - Charger, accumulator battery and USB cable. The kit also includes instructions. "Samsung Galaxy Core 2 Duos" is sold with a guarantee, so you need to check the availability of a coupon. It must be filled in by the seller on the day of the sale. Among the documentation you can see a list of accessories and addresses of the service center.

Design

The external design of the smartphone is quite typical for modern mobile devices. However, if you look in more detail, then the original "Samsung" design features are clearly visible. Users claim that it is almost impossible to confuse a Samsung Galaxy Core 2 Duos phone with a device from another brand.

The case is rectangular, the corners are slightly rounded. The manufacturer chose an inexpensive material for the main surfaces - plastic. Around the perimeter of the phone is a silver frame made of metal. It also frames the screen, giving the design originality. This material also influenced the formation of weight. With dimensions of 13.03 × 6.9 × 0.98 cm, the smartphone weighs almost 140 g.

On the front panel, the user will not see new elements. There is a screen here. The bezel that surrounds the display changes color depending on the color of the case. It thickens in the upper and lower sides. This solution was used in order to arrange important elements. We are talking about the speaker grill, sensors, "window" front camera, control panels. The latter is equipped with three keys. One of them is mechanical, the rest are sensory.

The rear panel is clearly distinguished by the coating feature. The cover is made of plastic, but its surface imitates genuine leather. This decision is well accepted by users. In the hand is very comfortable, does not slip. The back cover is quite pleasant to the touch. Functional elements are located only in the upper half. Here is the speaker hole, main camera lens and flash. There was also a logo. On the black lid, the inscription is presented in white, and the silver tint is used in devices with a white case.

"Samsung Galaxy Core 2 Duos": screen characteristics

One of the main elements of a smartphone, of course, is the display. In this model, due to cost reduction, the manufacturer preferred the modest characteristics of the screen. It is based on the classic TFT TN matrix. This suggests that owners will have to limit themselves to poor viewing angles. Also, such a matrix is ​​characterized by poor color reproduction. Outdoors in bright sunlight, the information displayed on the screen becomes almost unreadable. There is no anti-reflective coating due to the budget of the device.

The screen itself has a diagonal equal to 4.5 ʺ. The resolution, as for modern smartphones, is very small - only 800 × 480 px. The picture is not displayed well enough. Distortions in color and clarity are noticeable. You can only adjust the brightness manually. sensor for auto tuning missing on the phone. Many users talk about the quality of the sensor. Almost 80% of owners had problems with his work after a year of operation. It is important to pay attention to the fact that the device must be protected from moisture. If even a single drop of water penetrates, the sensor will not function properly. Users have noticed that the phone starts to open / close applications on its own, reboot, and even dial numbers from the address book.

On the this smartphone cannot be installed modern games but the simple ones work great. Multi-touch, which supports up to five simultaneous touches, will allow you to work with the device without any obvious restrictions.

In the factory, the screen is protected by a film. However, it will be inconvenient to use the phone with it, since its surface contains brief characteristics. If owners want to extend the life of the sensor and protect the screen, you will need to additionally purchase a special transparent film.

Performance

Samsung Galaxy Core 2 Duos, like many other models of the Korean manufacturer, runs on a Spreadtrum trademark processor. The SoC SC7735 chip is ideal for "state employees". This model is considered an analogue of the Taiwanese MT6582 processor. Their characteristics are almost identical. The chipset operates on four computing modules. Its performance is limited clock frequency at 1200 MHz, and this is the maximum that the device is capable of.

The processor is paired with a Mali 400 graphics accelerator. This video card model does not have high performance, but is capable of displaying a picture with a resolution of 800 × 480 pixels. Because of these indicators graphic settings at maximum elevations, the user will not be available. But for animated themes or viewing pictures (photos), they are quite enough.

Camera Features

"Samsung Galaxy Core 2 Duos" takes a low quality photo. The reason for this is the low resolution of the matrix. The main optics is presented to the buyer as a 5-megapixel camera. However, if you conduct testing, the results are somewhat less than such a resolution. In order for the photo to be of high quality, you will have to shoot only outdoors in daylight. For example, a winter or summer landscape is obtained with virtually no noise. To increase the possibilities, the manufacturer has provided autofocus and flash. Maximum size the size of the photo taken by the main camera is 2592 × 1944 px. The smartphone also has a video recording mode. Its speed per second is limited to 30 frames. The maximum resolution is 720 × 480 px.

Unfortunately, the front camera module has very poor performance. It is based on a 0.3-megapixel matrix. It is clear that you should not even dream of a selfie. Users are advised to use the main camera for this purpose, adjusting the viewfinder. As a rule, the front camera is only suitable for video calls.

autonomy
