Samsung galaxy core 2 technical specifications. Operating system and software

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

Technical Samsung specifications Galaxy Core 2 Duos are quite ordinary 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 maximum settings Don't expect graphics.

Memory

Where budget and mid-range Samsung smartphones can stand out is the amount of RAM. 768 MB random access memory You can hardly find it from other manufacturers. There is only one solution to this: Samsung, in addition to smartphones and household appliances, is also engaged in the manufacture of 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 with its products 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. 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 disadvantage free space compensates for 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 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 don't turn out that bad. On a winter day there is almost no noise, just like in a properly “captured” summer landscape.

Example of a main photo Samsung camera 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 back cover Samsung Galaxy Core 2 Duos hides 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.

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. Absolutely modern model
, although it does contain 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 you turn on Yandex Navigator: either the GPS takes a long time to search, or mobile network
It catches weakly - 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.

Great model

Review No. 2 about the Samsung Galaxy Core 2 Duos SM-G355H/DS phone

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

Advantages of the phone Solid design, bright screen, 4 cores Disadvantages of the phone: Excessively high power consumption, no standard MP3 player, small keyboard buttons, inconvenient to end a call.

Disadvantages of the phone: Reception is not always reliable

A week and a half ago I purchased a Samsung Galaxy Core 2. During this time, disadvantages emerged, and very, very significant ones (see disadvantages). This Samsung disappointed me even more than Sony Xperia M. The worst thing is that it’s inconvenient to reset the call, because... need to unlock the screen! And the fact that there is no standard MP3 player is also very surprising - I thought that any modern smartphone should have a standard player! I tried to download - there was not a single normal player! If it were not for these 2 jambs, then the remaining shortcomings could be put up with. Today I forcibly returned this Samsung and took the HTC 310.

Advantages of the phone Assembly without backlash
Screen and phone size
2 SIM cards Disadvantages of the phone: Screen viewing angles

Disadvantages of the phone: Reception is not always reliable

For a large man's hand the phone is comfortable and the size is optimal. Screen more or less. Viewing angles are average. The brightness and contrast of the picture are normal. Sensor review: 8 out of 10. Camera: In general, the picture is clear, juicy, and of course with color noise. The second camera for Skype is normal - enough for communication: faces, hairstyles, facial expressions, the surroundings, it shows everything. Calls: the speaker is loud, can be heard throughout the room, quality is 7 out of 10. Problems with calls (people cursed in reviews) - so here it is: download and read the instructions, and then criticize. Android KitKat – the phone has a minimal set of Google junk. Therefore, you will have to install whatever your heart desires into your phone, according to your taste and color (I think this is normal for a smart phone). GPS works great. He set a path for checking on foot - so he led me through the courtyards, exactly the way I walk. Music: Aimpa is enough for me. Not very convenient with SMS, does not save drafts, although there is a delayed sending function.
During three weeks of use, the phone never froze, there were no errors or other system troubles, although there were some minor glitches with programs during installation or updating. The battery after overclocking reliably lasts for two days: talking on the phone for 30 minutes a day with dual-SIM signal reception; reading books 2-3 hours a day; Internet (Wi-Fi) 1-1.5 hours a day; music via bluetooth headphones 30-40 minutes a day; sometimes GPS – 30 min. Naturally, everything needs to be configured so that energy is consumed rationally.

Samsung Galaxy Core 2 SM-G355H phone price

Market price at the time of page creation

Samsung has been delighting customers 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. 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. Everything that will be available to the user is Charger, accumulator battery And 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, “window” front camera, control panels. 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. Sensor for automatic settings not available on 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.

On this smartphone You can't install the latest games, 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.

In the factory configuration, the screen is protected with film. However, it will be inconvenient to use the phone with it, since on its surface there are brief characteristics. 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 2000 mAh batteries. At first glance, such a resource is not enough for the smartphone to fully operate. But when small screen, which is 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, then the battery life will be 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, the volume of which 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. Wireless way Bluetooth data transfer is also available in this model. The smartphone supports navigation systems A-GPS, GPS, GLONASS. 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 turned on for the first time, automatic start settings wizard. With this program you can set the language and change the time in a matter of seconds. Also, if desired, the user is invited to register accounts in in social networks, create mail and so on. 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”.

Finally, we will introduce readers to the reviews 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 a large amount of memory or best processor.
