Great model
Advantages of the phone Screen, decent speed, modern OS, price and everything else. Disadvantages of the phone: Reception is not always reliable
Comment about the phone:
I think I won’t be wrong if I say that the phone currently has no alternative for its money. I've been using it for almost a month.
An absolutely modern model, although it contains some compromises. So, there are no light or 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).
Overall it works quickly and smoothly, all applications launch and run without problems.
The downside is, perhaps, periodic difficulties with reception when 2 SIM cards are installed. When there is one, no problems arise, when there are 2, it can lose and find the network again a couple of times a day. It also doesn’t always start working quickly when Yandex Navigator is turned on: either the GPS search takes a long time, or the mobile network has poor reception - so it’s easier to reboot.
Reboots very quickly. Within 20-30 seconds, after which everything is usually ready to go, although perhaps this is because I haven’t had time to properly mess it up :)
In general, who needs a decent modern smartphone at a reasonable price, slightly higher than its “Chinese analogues” - buy it, you will be satisfied.
Review No. 2 about the Samsung Galaxy Core 2 Duos SM-G355H/DS phone
Great model
Phone experience: less than a month
Advantages of the phone: Fast, powerful. The screen, although 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, I set the special features to hang up on the on/off key, and you don’t need to point your finger at the screen to unlock and then hang up
No film on screen
There are no pictures for the background
I don’t understand how to install widgets
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. Our review will help you find out what the buyer will get for this money.
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 speaker are located symmetrically. Samsung Galaxy Core 2 Duos presented in black and white colors.
Specifications Samsung Galaxy Core 2 Duos SM-G355H
The technical characteristics of the Samsung Galaxy Core 2 Duos are quite normal for an inexpensive device. But at the same time, the device’s processor has four cores. In general, the filling of the smartphone is quite budget-friendly.
CPU
The use of Spreadtrum processors for Samsung is not something new. South Korean devices have been released using chips from this company before. 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 be slightly superior in performance (especially in games) to its competitors. 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. 768 MB of RAM is almost impossible to find from other manufacturers. There is only one solution to this: Samsung, in addition to smartphones and household appliances, also produces memory chips. Since today these 256 MB ones are no longer in use (to get 1 GB of RAM you need to solder as many as 4 chips on the board, and this is more difficult and more expensive than 1 1024 MB or 2 512 MB each), 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 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. Compared to the cheap devices remaining on sale with 512 MB, it looks attractive, but for 2015 it’s not enough.
About half of the 4 GB flash drive is provided for storing user content in the smartphone. Fortunately, the lack of free space is compensated by the presence of a MicroSD slot. Samsung Galaxy Core 2 Duos supports flash drives with a capacity of up to 64 GB.
Battery
A 2000 mAh battery is normal for a budget employee. Moreover, the screen of the Samsung Galaxy Core 2 Duos is not that large. 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 games. For a $100 smartphone, that's not bad.
Camera
The Samsung Galaxy Core 2 doesn't deserve to be called a camera phone. 5 MP today is good for the front camera, but not the main module. At the same time, the pictures are not that bad. On a winter day there is almost no noise, just like in a properly “captured” summer landscape.
An example of a photo taken with the main camera of a Samsung Galaxy Core 2
The room is a little worse, but not downright bad. To be honest, we came across “Chinese” ones that even at 8 MP demonstrated disgusting quality. Therefore, we can safely assure you: for a 5 MP camera, the Samsung Galaxy Core 2 Duos has a good camera. Moreover, there is a flash, and autofocus is not possible.
The front module has a resolution of 640x480 and is intended purely for video communication. There is no point in trying to take a good quality selfie with it - it is better to turn the smartphone with the back side and “blindly” take 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 budget, 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 the back cover of the Samsung Galaxy Core 2 Duos there are two slots for SIM cards. They have a MicroSIM format, which is beneficial 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.
Network standards supported are GSM and UMTS/HSDPA. 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”. It's loud and doesn't wheeze, but the frequency range lets us down. Listening to music with headphones is much more pleasant - there is at least a hint of bass there. To be fair, it is worth noting that Samsung is not the only one guilty of this. So, among its competitors, the Galaxy Core 2 Duos deserves a solid six (out of ten). And considering that the smartphone also has a radio (unlike some flagships), the multimedia side cannot be considered a minus.
operating system
The operating system on the Samsung Galaxy Core 2 Duos is Android 4.4. Naturally, it would not have been possible without the TouchWiz interface. The smartphone uses a stripped-down version of the shell, which is less functional than that of flagships, but given the small amount of RAM, this is not a minus, but a plus.
Pros and cons of Samsung Galaxy Core 2 Duos SM-G355H
Advantages of Samsung Galaxy Core 2 Duos:
- good battery;
- quad-core processor;
- low price;
- support for 64 GB memory cards;
- good (for its class) camera.
Disadvantages of a smartphone:
- mediocre display;
- "dry" sound.
Our review of the Samsung Galaxy Core 2 Duos SM-G355H
After reviewing the Samsung Galaxy Core 2 Duos, we can note that this inexpensive device corresponds 100% to its class. Compared to the flagships, it looks very modest, but if we are objective, we can’t call it bad. The Samsung Galaxy Core 2 Duos has everything that users who are not chasing megapixels, gigabytes and gigahertz need. For Internet surfing, working with email and social networks, watching videos - its capabilities are more than enough.

Review of XiaoMi Redmi 3: compact budget phone with a good battery
Samsung has been delighting customers with its mobile devices for several years now. Its model range includes 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. Considering 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 low-cost phone segment. Buyers were pleasantly surprised to learn about the decent functionality of this gadget. Of course, it cannot handle flagship tasks, but the device is ideal for everyday use. According to the owners, the manufacturer was able to achieve the optimal balance between cost and quality.
What characteristics and features does a smartphone have? What technologies did the manufacturer use? The answers to these questions can be found in the article.
Delivery and packaging
For the packaging box of the Korean Samsung Galaxy Core 2 Duos phone, a natural wood pattern was used as a basis. The designers were also able to reproduce the natural shades of the color palette. The company logo appears 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 edge there is a serial individual number of the device and information about the country in which the assembly was made. The other describes in detail the main characteristics of the device.
What's inside this box? The delivery set can be safely called standard. Judging by the range 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, a battery and a USB cable. The kit also includes instructions. Samsung Galaxy Core 2 Duos is sold with a warranty, so you need to check the availability of the coupon. It must be completed by the seller directly on the day of sale. Among the documentation you can see a list of accessories and service center addresses.
Design
The external design of the smartphone is quite typical for modern mobile devices. However, if you look in more detail, the original “Samsung” design features are clearly visible. Users claim that it is almost impossible to confuse the Samsung Galaxy Core 2 Duos with a device from another brand.
The body is rectangular, the corners are slightly rounded. The manufacturer chose an inexpensive material for the main surfaces - plastic. A silver frame made of metal runs along the entire perimeter of the phone. 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.
The user will not see new elements on the front panel. There is a screen here. The frame surrounding the display changes color depending on the color of the case. It thickens on the upper and lower sides. This solution was used to arrange important elements. We are talking about the speaker grille, sensors, the front camera “window”, and the control panel. The latter is equipped with three keys. One of them is mechanical, the rest are sensory.
The back panel stands out with its special coating. The lid is made of plastic, but its surface imitates genuine leather. This decision was accepted very well by users. It lies very comfortably in the hand and does not slip. The coating on the back panel is quite pleasant to the touch. Functional elements are located only in the upper half. Here is the speaker hole, the main camera lens and the flash. There was also a logo. On the black lid the inscription is presented in white, and a silver tint is used in devices with a white body.
"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 gave preference to modest screen characteristics. It is based on a classic TFT TN matrix. This suggests that owners will have to make do with poor viewing angles. Also, such a matrix is characterized by poor color rendering. On the street in bright sunshine, the information displayed on the screen becomes almost unreadable. There is no anti-reflective coating due to the budget nature of the device.
The screen itself has a diagonal of 4.5 inches. The resolution, like for modern smartphones, is very small - only 800 × 480 px. The picture is not displayed well enough. Distortions in color and clarity are noticeable. Brightness can only be adjusted manually. There is no sensor for automatic tuning in the phone. Many users talk about the quality of the sensor. Almost 80% of owners began having problems with its operation after a year of operation. It is important to pay attention to the fact that the device must be protected from moisture. If even one drop of water penetrates, the performance of the sensor will be impaired. Users noticed that the phone independently began to open/close applications, reboot, and even dial numbers from the address book.
You cannot install the most modern games on this smartphone, but simple ones work great. Multi-touch, which supports up to five simultaneous touches, will allow you to work with the device without obvious restrictions.
As standard, the screen is protected with film. However, it will be inconvenient to use the phone with it, since brief characteristics are presented on its surface. If owners want to extend the operation of the sensor and protect the screen, they will need to additionally purchase a special transparent film.
Performance
The Samsung Galaxy Core 2 Duos, like many other models from the Korean manufacturer, runs on a Spreadtrum brand processor. The SC7735 SoC chip is ideal for budget employees. This model is considered an analogue of the Taiwanese processor MT6582. Their characteristics are almost identical. The chipset operates on four computing modules. Its performance is limited to a clock frequency 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 an image 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 sufficient.
Camera Features
The Samsung Galaxy Core 2 Duos takes low quality photos. The reason for this is the poor resolution of the matrix. The main optics are presented to the buyer as a 5-megapixel camera. However, if testing is carried out, the results fall somewhat short of this 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 capabilities, 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. Maximum resolution - 720 × 480 px.
Unfortunately, the front camera module has very weak characteristics. It is based on a 0.3 megapixel matrix. It’s clear that you shouldn’t even dream about taking a selfie. Users advise using the main camera for these purposes, adjusting the viewfinder. As a rule, the front-facing 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 limitations. It is in the budget segment that there are many devices that are equipped with batteries with a capacity of 2000 mAh. At first glance, such a resource is not enough for the smartphone to fully operate. But with the small screen installed in this model, the charge is consumed quite economically. To achieve a 100 percent charge with a discharged battery, you will need to spend 3 to 4 hours, provided you use the original charger.
Users claim that the smartphone will last about 2 days when making calls. In Internet browsing mode, the battery will have to be charged after 10 hours. You can record and play videos 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, the battery life will be 30 hours.
Memory storage
The Samsung Galaxy Core 2 Duos is a typical budget phone, as evidenced by the amount of RAM. It is only 768 MB. Of course, for those people who are accustomed to using the full potential of their smartphone to the maximum, such indicators are very few. However, the phone is quite capable of solving everyday problems.
Now it’s worth considering native memory storage. 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 whose capacity does not exceed 64 GB.
Communications
Samsung Galaxy Core 2 Duos is equipped with all the interfaces necessary to transmit and receive information. The device works with GSM and 3G networks. Wi-Fi is provided for connecting to the Internet. Bluetooth wireless data transfer is also available in this model. The smartphone provides support for A-GPS, GPS, GLONASS navigation systems. Just like other similar devices, the model has a standard audio port and a microUSB connector.
Operating system and software
Samsung Galaxy Core 2 Duos runs on the most popular operating system - Android. The developers used version 4.4.2. When you turn it on for the first time, the settings wizard will automatically launch. With this program you can set the language and change the time in a matter of seconds. Also, if desired, the user is asked to register accounts on social networks, create an email, etc. When you initially connect to the Internet, some operating system files are updated. Those users who do not want to install them can make the appropriate changes in the settings by selecting “Always ask”.
Samsung Galaxy Core 2 Duos phone: owner reviews
Finally, we will introduce readers to reviews from real owners. They will help give a true assessment of the smartphone. In their opinion, the phone turned out great. It has enough functionality, it copes with all everyday tasks. The characteristics are modest; already in 2015 one could find gadgets with more memory or a better processor. But brand connoisseurs still did not change their habits.

Super AMOLED- if a regular 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 its higher resolution, thanks to which you can 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 a larger number of subpixels in a conventional RGB matrix. The new displays are 18% thinner and brighter than displays made using the old 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 larger color gamut, reduced thickness and the ability of the display to bend slightly without the risk of breaking.
Retina-high pixel density display designed specifically for Apple technology. The pixel density of Retina displays is such that individual pixels are indistinguishable to the eye at a normal distance from the screen. This ensures the highest image detail and significantly improves the overall viewing experience.
Super Retina HD- the display is made using OLED technology. The pixel density is 458 PPI, the contrast reaches 1,000,000:1. The display has a wide color gamut and unsurpassed color accuracy. Pixels in the corners of the display are smoothed at the sub-pixel level, so edges are not distorted and appear smooth. The Super Retina HD reinforcing layer is 50% thicker. It will be harder to break the screen.
Super LCD is the next generation of LCD technology, it is characterized by improved characteristics compared to earlier LCD displays. The screens not only have wide viewing angles and better color reproduction, but also lower power consumption.
TFT- A common type of liquid crystal display. Using an active matrix controlled by thin-film transistors, it is possible to significantly increase the performance of the display, as well as the contrast and clarity of the image.
OLED- organic electroluminescent display. It consists of a special thin-film polymer that emits light when exposed to an electric field. This type of display has a large reserve of brightness and consumes very little energy.
