TFT IPS- High-quality liquid crystal matrix. It has wide viewing angles, one of the best indicators of color reproduction quality and contrast among all those 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 greater screen brightness with the same power consumption.
Super AMOLED HD- differs from Super AMOLED in a higher resolution, thanks to which it is possible to achieve 1280x720 pixels on a mobile phone screen.
Super AMOLED plus- this is a new generation of Super AMOLED displays, differs from the previous one by using more sub-pixels in a conventional RGB matrix. The new displays are 18% thinner and 18% brighter than the older PenTile displays.
AMOLED- an improved version of OLED technology. The main advantages of the technology are significantly reduced power consumption, the ability to display a large color gamut, a smaller thickness and the ability of the display to bend a little without the risk of breaking.
retina- display with a high pixel density, designed specifically for Apple technology. The pixel density on Retina displays is such that individual pixels are indistinguishable to the eye at a normal distance from the screen. This provides the highest image detail and greatly 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 an extended color gamut and unrivaled color accuracy. Pixels in the corners of the display are anti-aliased at the sub-pixel level, so borders don't distort and look smooth. Super Retina HD reinforcement layer is 50% thicker. Breaking the screen will be harder.
Super LCD is the next generation of LCD technology and features improved features compared to earlier LCD displays. Screens have not only wide viewing angles and better color reproduction, but also reduced power consumption.
TFT- A common type of liquid crystal displays. With the help of an active matrix, controlled by thin-film transistors, it is possible to significantly increase the speed of the display, as well as the contrast and clarity of the image.
OLED- organic electroluminescent display. Consists of a special thin-film polymer that emits light under the influence of an electric field. This type of display has a large margin of brightness and consumes very little power.
Core 2, the characteristics of which will be given in today's review, is a budget solution from a 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 the mark of 7,000 rubles. You can buy 2, the characteristics of which raise a number of questions not only among those who want to purchase the device, but also among those who have already bought it, in some stores. For example, in the retail network MTS.
Brief information
Samsung Galaxy Core 2 G355H, the characteristics of which are soberly assessed by experts as a three-plus, is a typical representative of the budget class and has a 4.5-inch screen. A small device that can fit in the palm of one's hand. At the same time, it will be quite convenient to operate it in the sense that the thumb freely reaches any point of the display, right to the very corners. With permission, the developers, of course, screwed up. However, more on that later. On board we are waiting for not quite fresh, but quite a working version of the operating system of the Android family. This is version 4.4. With offline work, not everything is as good as we would like. The same can be said about the camera with a resolution of five megapixels. 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 can see that the edges of the device are rounded. Well, this is a very good solution, and there can be no complaints about this parameter. The phone lies neatly, tightly, reliably in the hand, but all this is only under normal conditions. If your hands sweat or get wet from water, the device tends to slip out of your hands, which is not good.
Manufacturing materials
Samsung Galaxy Core 2, the characteristics of which we cited at the beginning of the article, is made of plastic and metal. Rather, its front panel is made from the latter material. Actually, therefore, some massiveness is felt at the output. Nevertheless, it is very, very difficult to call this model a “brick”. And the point here is a number of weight and size factors. In principle, there should be no complaints on this point. Move on. That's just the back cover of the smartphone is made of plastic coated with soft-touch. It seems to be a good practical solution, which is used almost everywhere. However, there are pitfalls here. It has already been said earlier that the phone seems to be securely. But as soon as you touch it with wet hands, the reliability of the hold begins to fall rapidly.
Minuses
Another disadvantage of the back cover is the fact that its lower part begins to rub over with time. And it is very noticeable from the outside. So that the buyer does not think that everything is very bad, we can give one advantage that should at least compensate for the listed shortcomings, because it is unlikely that they will be able to block with a plus. The back cover has a corrugated surface. This will save the buyer from sticking fingerprints and scratches.
Controls
The front face of the characteristics of which, in some respects, contradict each other, will show us the screen itself. It has a diagonal of 4.5 inches. Above is the grille of the sound speaker, 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. Below the screen are the navigation buttons. 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 from the sensor elements did not peel off, for which thanks 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 side. As we can see, unlike the same, these elements are spaced on different sides. However, there should be no complaints about this, since operating the device does not become less comfortable. Note that none of the keys has backlash. The device is assembled soundly, does not creak when twisted. There is a drawback in the body, which concerns the chrome coating (edging): it will wear off, and at an active pace.
Display
The budget segment of the South Korean company in this regard has not pleased many users 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 screen with a diagonal of 4.5 inches. This is a TFT matrix. In fact, IPS would fit here. But the developers decided in their own way, probably because of the low battery capacity (less than 2,000 milliamps per hour). Yes, there are indeed 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 hits, the device starts randomly opening and closing applications, dialing numbers and writing messages.
Hardware platform and performance
Samsung G355H Galaxy Core 2 Duos, the characteristics of which 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. On board there is already an operating system of the "Android" family of version 4.4. Not the best option, but it is ideal for such a mediocre filling. Sometimes sometimes it seems that something simpler is needed, 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 must be simple programs. Otherwise, "brakes" may begin.
Samsung Galaxy Core 2 SM-G355H: features from users and reviews
In general, the phone does not deserve special attention. In the price category where the device is located, there are a sufficient number of more productive and pleasant analogues. A lot of users complain about the smartphone camera. If the main module shoots even more or less acceptable in good light conditions, then the front camera is a real horror. It is difficult to single out any positive qualities of the device. One could say that we have a good workhorse for surfing the Web, but this does not allow us to do a not very high-quality 3G module and a low battery charge. With active use of social networks, the device will turn off after lunch.
Excellent model
Advantages of the phone Screen, decent speed, modern OS, price and everything else. Disadvantages of the phone: Not always a good reception
Phone comment:
I think I won’t be mistaken if I say that for my money the phone has no alternative at the moment. I've been using it for almost a month.
Absolutely modern model, although it contains some compromises. so, there are no light and conversation sensors, a small amount of RAM and hard memory for 2014 (although I had the same amount on my PC about seven years ago).
In general, it works quickly and smoothly, all applications run 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 a couple of times a day and re-find the network. And also it doesn’t always quickly turn on when Yandex Navigator is turned on: either GPS searches for a long time, or it catches the mobile network weakly - so it’s easier to reboot.
Reloads very quickly. Within 20-30 seconds, after which everything is usually ready to go, although perhaps this is because I have not had time to spoil it properly :)
In general, who needs a decent modern smartphone for a reasonable price, slightly higher than the "Chinese counterparts" - buy, you will be satisfied.
Review #2 about Samsung Galaxy Core 2 Duos SM-G355H/DS
Excellent model
Phone experience: less than a month
Advantages of the phone Fast, powerful. The screen, though TN, is as bright as IPS for 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 automatically locks when you start a conversation. But for the convenience of ending a call in special features, I set it to hang up on the on / off key, and you do not need to poke your finger into the screen to unlock and then hang up
No film on screen
There are no background pictures
I do not understand how to put widgets

Samsung has been pleasing the buyer with its mobile devices for several years now. In its lineup 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 its power, but the device fits perfectly for everyday use. 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. The company logo flaunts in the upper left corner of the front panel. 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. All that will be available to the user is a charger, rechargeable 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 grille, sensors, the "window" of the front camera, the control panel. 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. There is no sensor for automatic adjustment in 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.
You can’t install the most modern games on this smartphone, but simple ones work fine. 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, as brief characteristics are presented on its surface. 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 to a clock speed of 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. Due to such indicators, graphic settings at maximum levels will not be available to the user. 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. The maximum size of a photo taken with 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
The battery for the Samsung Galaxy Core 2 Duos was selected by the developers based on cost constraints. It is in the budget segment that there are many devices that are equipped with 2000 mAh batteries. At first glance, such a resource is not enough for the full operation of the smartphone. But with a small screen, which is installed in this model, the charge is consumed quite sparingly. It will take 3 to 4 hours to achieve a 100% charge with a dead battery, using the original charger.
Users claim that when making calls, the smartphone will work for about 2 days. In Internet browsing mode, you will have to charge the battery after 10 hours. You can record and play video for the same amount of time. When playing games, the battery will run out in 5 hours. If you turn off the network and use the phone as a player, then the battery life will be 30 hours.
Memory storage
"Samsung Galaxy Core 2 Duos" is a typical "state employee", this is evidenced by the amount of RAM. It is only 768 MB. Of course, for those people who are used to using the full potential of a smartphone to the maximum, there are very few such indicators. However, the phone is quite capable of solving everyday tasks.
Now it is worth considering the storage of native memory. It will allow users to download applications, music and more. In the specifications, the manufacturer indicates 4 GB, but in reality no more than half will be available. In order to compensate for the lack of space, the developers have provided support for memory cards. The device works with external drives, the volume of which does not exceed 64 GB.
Communications
