The warranty period of the smartphone samsung galaxy kore 2. The screen of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc.
Samsung Galaxy Core 2 Duos SM-G355H has become the next model in the "galactic" line of the South Korean electronics giant. The smartphone aimed at the budget price niche went on sale in June 2014. Now you can buy the device for about $ 100. What the buyer will get for this money - our review will help to find out.
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. At the back, near the camera window, the flash LED and the speaker are symmetrically located. Presented Samsung Galaxy Core 2 Duos in black and white.
Specifications Samsung Galaxy Core 2 Duos SM-G355H
Specifications Samsung 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 were released earlier. This time, the manufacturer used the SoC SC7735 platform, which is the closest analogue of 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 the 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 performance (especially in games). But in reality, the difference is not felt either by eye or in benchmarks. And the same AnTuTu shows an even lower score (15 thousand versus 17-18 for MTK). This is enough for games, but you shouldn't expect maximum graphics settings.
Memory
Where budget and mid-range Samsung smartphones can stand out is the amount of RAM. You can hardly find 768 MB of RAM from 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 these 256 MB are no longer in use (to get 1 GB of RAM, you need to unsolder as many as 4 chips on the board, and this is more complicated and more expensive than 1 for 1024 or 2 for 512 MB), the company equips its products with inexpensive devices of its own 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 meaning 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 juices" out of a smartphone. Against the background of the cheap devices with 512 MB remaining on sale, it looks attractive, but for 2015 it is already not enough.
For storing user-generated content, the smartphone provides about half of the 4 GB flash drive. Fortunately, the lack of free space makes up for the presence of a microSD slot. Samsung Galaxy Core 2 Duos supports flash drives up to 64GB.
Battery
A 2000 mAh battery is normal for a budget employee. Moreover, the screen of the Samsung Galaxy Core 2 Duos is not that big. The battery 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 games. For a $ 100 smartphone, that's not bad.
Camera
The title of a cameraphone Samsung Galaxy Core 2 does not pull in any way. 5 MP today is good for a front camera, but not for the main module. However, the pictures are not so bad. On a winter day, there is almost no noise, however, as well as on a correctly "captured" summer landscape.
Sample shot on the main camera Samsung Galaxy Core 2
The room is a little worse, but not to say that frankly bad. To be honest, we came across "Chinese" who demonstrated disgusting quality even at 8 MP. Therefore, we can safely assure: for 5 MP, the Samsung Galaxy Core 2 Duos has a good camera. Moreover, there is a flash, and it was not without autofocus.
The front module has a resolution of 640x480 and is intended exclusively for video communication. Trying to take a good quality selfie on him is not worth it - it is better to turn the smartphone with the back side, and “blindly” shoot five frames, each time tilting the device slightly 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 4.5 "diagonal. 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 the back cover of the Samsung Galaxy Core 2 Duos, there are two SIM card slots. They are in MicroSIM format, which is beneficial in terms of saving space. Because of this, owners of old-format chips will have to go to the operator for a replacement or cut them off on their own.
The networks support GSM and UMTS / HSDPA standards. In addition, you can maintain a high-speed connection only with 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 really budget-friendly. It is loud, does not wheeze, but the frequency range let us down. It is much more pleasant to listen to music in headphones - there is at least a hint of bass there. To be fair, it's worth noting that Samsung isn't the only one to blame for 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 as a minus.
Operating system
The operating system on the Samsung Galaxy Core 2 Duos is Android 4.4. Naturally, the TouchWiz interface was not without. The smartphone uses a stripped-down version of the shell, which is less functional than that of the flagships, but against the background of a small supply of RAM, this is not a minus, but a plus.
Pros and cons of Samsung Galaxy Core 2 Duos SM-G355H
Samsung Galaxy Core 2 Duos advantages:
- good battery;
- quad-core processor;
- low price;
- support for memory cards 64 GB;
- good (for its class) camera.
Disadvantages of a smartphone:

XiaoMi Redmi 3 review: a compact budget phone with a good battery
Core 2, the characteristics of which will be given in today's review, is the budget solution of the South Korean company. On the territory of the Russian Federation, as of 2015, the cost of the device was 7,500 rubles. After almost a full year, it dropped to 7,000 rubles. You can buy 2, the characteristics of which raise a number of questions not only from those who want to buy the device, but also from those who have already bought it, in some stores. For example, in the MTS retail network.
Brief information
Samsung Galaxy Core 2 G355H, the characteristics of which are soberly evaluated by experts at the top three, is a typical representative of the budget class and has a screen with a diagonal of 4.5 inches. A small device that can fit in one palm. At the same time, it will be quite convenient to operate them in the sense that the thumb freely reaches any point of the display, right to the very corners. With permission, the developers screwed up, of course. However, more on that later. On board we are expected not quite fresh, but quite working version operating system of the "Android" family. This is version 4.4. With battery life, not everything is as good as we would like. The same can be said for the five megapixel camera. The entire set of necessary communications is present, with the exception of the 4G LTE module.
Design
Samsung Galaxy Core 2, the characteristics of which can be found above, shows us the continuation of the design line that the specialists of the South Korean company bend. In some ways, they decided to move away from their traditions, abandoning rectangular shapes. You will notice that the edges of the device are rounded. Well, this is a very successful decision, and there can be no complaints about this parameter. The phone lies in the hand neatly, tightly, reliably, but all this is only under normal conditions. If your hands sweat or get wet from water, the device tries to slip out of your hands, which is not good.
Manufacturing materials
Samsung Galaxy Core 2, the characteristics of which we gave at the beginning of the article, is made of plastic and metal. Rather, its front panel is made from the latter material. Actually, that's why some massiveness is felt at the exit. Nevertheless, it is very, very difficult to call this model a “brick”. And the point here is in a number of weight and size factors. In principle, there should be no complaints about this point. Move on. The back cover of the smartphone is made of soft-touch plastic. It seems to be a good practical solution that is used almost everywhere. However, there are pitfalls here. Earlier it was said that the phone seems to be securely in place. But as soon as you touch it with wet hands, the reliability of holding begins to fall rapidly.
Minuses
Another drawback of the back cover is the fact that the lower part of it begins to wear over time. And this is very noticeable from the outside. So that the buyer does not think that everything is very bad, we can cite one advantage that should at least compensate for the listed disadvantages, because it is unlikely that it will be possible to block them with a plus. The back cover has a grooved surface. This will save the customer from fingerprints and scratches.
Control elements
The front face of the characteristics of which in some sense contradict each other, the screen itself will demonstrate to us. It has a diagonal of 4.5 inches. Above is the speaker grill, to the right of it is the front camera peephole. Under the speaker there is an inscription Samsung, to the right - Duos. Yes, the device supports two SIM cards. Navigation buttons are located under the screen. Two of them ("Back" and "List of applications") are touch-sensitive, and the "Home" key, located in the middle, is mechanical. For a long time of operation, the paint did not peel off the sensor elements, for which we are grateful to the developers.
Parties
Samsung Galaxy Core 2 Duos, the characteristics of which appeared on the international network even before the presentation and release of the device, has a paired volume and sound mode key on the left side, and a lock button on the right. As we can see, in contrast to the same, these elements are spaced apart on different sides. However, there should be no complaints about this, since the device does not become less comfortable to operate. Note that none of the keys has any backlash. The device is assembled soundly, does not creak when twisted. There is a drawback in the case, which concerns the chrome plating (edging): it will wear off, and at an active pace.
Display
In this regard, the budget segment of the South Korean company has not made many users happy for a long time. We can observe the same in the case of the Samsung Galaxy Core 2 SM-G355H, the characteristics of which will be given below. So, we have a 4.5-inch screen installed. This is a TFT matrix. In fact, IPS would fit here. But the developers decided in their own way, probably due to the low capacity of the battery (less than 2,000 milliamperes per hour). Yes, indeed, there are savings. However, we will have to pay for this by the inability to read the text in bright sunlight. The picture fades very noticeably. By the way, there is no light sensor, which means that you will have to manually adjust the brightness level. The screen resolution is 480 by 800 pixels. After some time of use, the sensor will begin to behave inappropriately and live its own life. When one drop of water gets in, the device starts to randomly open and close applications, dial numbers and write messages.
Hardware platform and performance
The Samsung G355H Galaxy Core 2 Duos, which features quickly appeared in all specialized editions, is equipped with a quad-core processor with a clock speed of 1.2 GHz and 768 megabytes of RAM. The operating system of the "Android" family of version 4.4 is already on board. Not the best option, but perfect for such a mediocre filling. Sometimes it sometimes seems that you need something simpler, because the interface starts to work not quite smoothly, in jerks. The phone is not suitable for demanding games. You can open multiple applications at the same time, but they should be simple programs. Otherwise, “brakes” may start.
Samsung Galaxy Core 2 SM-G355H: characteristics from users and reviews
In general, the phone does not deserve special attention. In the price category where the device is located, there is a sufficient number of more productive and pleasant analogs. A lot of users complain about the smartphone camera. If the main module shoots even more or less acceptable in good lighting conditions, then the front camera is a sheer horror. It is difficult to single out any positive qualities of the device. We could say that we have a good workhorse for surfing the Web, but this is not possible with a low-quality 3G module and a low battery charge. With active use of social networks, the device will turn off after lunch.
Great model
Advantages of the phone Screen, decent speed, modern OS, price and everything else. Disadvantages of the phone: Not always reliable reception
A comment about the phone:
I think I won't be mistaken if I say that the phone has no alternative for its money. I have been using it for almost a month.
A completely modern model, although it contains some compromises. so, there are no light and talk sensors, a small amount of RAM and hard memory for 2014 (although I had the same on my PC about seven years ago).
In general, it works quickly and smoothly, all applications start and run without problems.
The downside is, perhaps, periodic difficulties with reception when 2 SIM cards are installed. When one - there are no problems, when 2 - it can lose and re-find the network a couple of times a day. And also, it does not always turn on quickly when Yandex Navigator is turned on: either GPS is looking for a long time, or the mobile network is catching poorly - therefore, it is easier to reboot.
Reboots very quickly. Within 20-30 seconds, after which everything is usually ready to go, although perhaps this is because I have not yet had time to properly dirtied it :)
In general, whoever needs a decent modern smartphone for a reasonable price, slightly higher than the "Chinese counterparts" - buy, you will be satisfied.
Review # 2 on the phone Samsung Galaxy Core 2 Duos SM-G355H / DS
Great model
Phone experience: less than a month
Advantages of the phone Fast, powerful. Although the screen is TN, it is bright like IPS in state employees.
The camera is good, the flash is very bright (it shines perfectly in flashlight mode). Disadvantages of the phone: There is no proximity sensor and the screen is automatically locked when you start talking. But for the convenience of completing a call in special features, I installed hang up on the on / off key, and you do not need to poke your finger at the screen to unlock and then hang up

TFT IPS- High quality liquid crystal matrix. Has wide viewing angles, one of the best indicators of color and contrast quality among all that are used in the production of displays for portable equipment.
Super AMOLED- if a conventional AMOLED screen uses several layers, between which there is an air gap, then in Super AMOLED there is only one such touch layer without air gaps. This allows you to achieve a brighter screen for the same power consumption.
Super AMOLED HD- differs from Super AMOLED in high resolution, thanks to which it is possible to achieve a size of 1280x720 pixels on the screen of a mobile phone.
Super AMOLED plus- This is a new generation of Super AMOLED displays, which differs from the previous one by using more subpixels in a conventional RGB matrix. The new displays are 18% thinner and brighter than the older PenTile technology.
AMOLED- an improved version of OLED technology. The main advantages of the technology are significantly reduced power consumption, the ability to display a wider color gamut, smaller thickness and the ability of the display to bend slightly without the risk of breaking.
Retina-display with high pixel density, designed specifically for Apple technology. Pixel density per Retina displays is such that individual pixels are indistinguishable to the eye at the normal distance from the screen. This provides the highest picture detail and dramatically improves the overall viewing experience.
Super Retina HD- the display is made using OLED technology. The pixel density is 458 PPI, the contrast ratio reaches 1,000,000: 1. The display has a wide color gamut and unrivaled color accuracy. Pixels in the corners of the display are anti-aliased at the sub-pixel level, so the edges stay flat and look flat. 50% thicker Super Retina HD gain layer. It will be harder to break the screen.
Super LCD is the next generation of LCD technology and offers improved performance over earlier LCD displays. The screens have not only wide viewing angles and better color reproduction, but also lower power consumption.
TFT- A common type of liquid crystal displays. The active matrix, controlled by TFTs, significantly improves display performance, as well as image contrast and clarity.
OLED- organic electroluminescent display. Consists of a special thin-film polymer that emits light under the action of an electric field. This type of display has a large margin of brightness and consumes very little power.
