Inexpensive, but at the same time a very functional economy class gadget is the Samsung Galaxy Core 2 Duos. Of course, it cannot boast of outstanding parameters and characteristics, but at the same time its computing power will be enough to solve most everyday tasks. At the same time, the price of this device is very modest.
And what comes as standard?
Not a bad, but not perfect equipment for this device. The list of accessories, in addition to the gadget itself, includes:
- 2000 mAh rated battery.
- Interface cord.
- Charger with 0.7A current output.
This list clearly lacks a stereo headset. This situation is typical for an entry-level device. Therefore, acoustics will have to be purchased separately. And without it, the radio - headphones will not function, in addition to its main function - reproducing an audio signal, in this case they also performthe role of the antenna. The body is made entirely of plastic. Therefore, you will also need a case and a protective film for the front panel. Well, a flash card will be useful in this smartphone.
Documentation includes:
- Warranty card.
- The business card of the South Korean giant, which contains all the contact details of service centers.
- User manual.
- Extended list of supported accessories.
Phone appearance and usability
Samsung DUOS 2 SIM smartphones have a fairly similar design, and it is very difficult to confuse them with devices from other manufacturers. The front panel of this unit has a 4.5-inch display. Above it are components such as earpiece, front camera and sensors. At the bottom are three main control keys. The central one is mechanical, and those located at the edges are sensory. The top edge has a standard audio port, the bottom one has a microphone and a MicroUSB port. The power button is located on the right side of the device, and on the left there are swings for adjusting the volume level. Diagonal display, as noted earlier, this device - 4.5 inches. Accordingly, it is not difficult to operate it with one hand.
CPU and its capabilities
"Samsung Galaxy Core 2 Duos" is based on the Shark processor developed by Spreadtrum. Its second name in accordance with the manufacturer's specifications is SC7735S. itQuad-core solution capable of running at 1.2 GHz under maximum load. Each of its computing modules is based on the A7 architecture. This chip cannot boast of a high level of performance, but its energy efficiency is at an acceptable level. Despite this, the computing resources of this CPU are quite enough to solve most problems both at the moment and in the foreseeable future.
Gadget and camera graphics
Mali-400 acts as a graphics accelerator in the phone. The use of this solution once again indicates the budget of the device. But still, the computing capabilities of this video accelerator are quite enough for a resolution of 480 x 800 px (this is exactly what the screen of this smartphone has). The display is capable of displaying 262 thousand different color shades, and it is based on the most economical matrix at the moment - TFT. As a result, the viewing angles of the device are far from 180 degrees. With a significant deviation from the right angle, the image is distorted. A very modest main camera of 5 megapixels is installed in this device. But at the same time, the developers did not forget to supplement it with an autofocus system and an LED flash. The quality of photos and videos is mediocre, but you can't expect more from an economy-class device. The front camera is based on the most modest 0.3 MP sensor. It is problematic to record high-quality photos and videos with its help. But still, for making video calls (and this is its main purpose), this is quite enough. But about a selfie in this case can notbe out of the question.
Memory
Samsung Galaxy Core 2 DUOS review will be incomplete if you do not specify the characteristics of the memory subsystem. It is difficult to understand what the developers were guided by when they installed 768 MB of RAM on this phone. This is slightly more than the required minimum of 512 MB, and below the comfortable level of 1 GB. It should be noted right away that 300-400 MB will be occupied by system processes. The rest, as expected, is provided to the user to solve their problems. The internal storage capacity is only 4 GB. Of these, about 2 GB are occupied by the operating system and pre-installed software. The user can use only 1.5 GB to install programs and store personal data. This volume is clearly not enough today. The only solution in this case may be to install an external flash card. Its maximum size can be 64 GB. Another way to solve the problem of lack of integrated memory is to use cloud services to store personal information.
Autonomy
Reviews of the Samsung Galaxy Core 2 DUOS smartphone indicate a good autonomy of the device. The capacity of the complete battery, as noted earlier, is 2000 mAh. According to the manufacturer, this talk time is enough for 9 hours. In reality, with an average level of use of the phone, one battery charge easily lasts for 2-3 days. This value is significantly affected by the diagonal of the screen (itis 4.5 inches - not that much today) and an energy-efficient processor based on the A7 architecture. If you use the gadget as economically as possible, then you can stretch one battery charge for 4 days. In terms of autonomy, this is one of the best smartphones in its niche.
Soft
As expected, the Samsung Galaxy Core 2 Duos operates under the control of the most popular and most common Android software platform. The current version of the firmware installed on it is 4.4. Obviously no updates to be expected. Yes, and it is not necessary. Software compatibility problems are not expected in the foreseeable future. Otherwise, the set of software is quite familiar for the entry-level device of the Galaxy line - this is the standard set of software from Google, and the built-in services of international social networks, and the usual mini-applications.
Communications
All the necessary interfaces for exchanging information are in the Samsung Galaxy Core 2 DUAL. "Galaxy Core 2 Duos" can operate both in GSM and 3G networks. In the first case, the transfer rate will be several kilobytes, in the second - several megabytes. There is also Wi-Fi, which is preferable to use with an impressive amount of traffic. The developers did not forget about the "Bluetooth". This wireless interface allows you to output an audio signal to a stereo headset or exchange small files with similar devices. There is also full support for GPS, GLONASS and A-GPS. All this allows the owner of this smartphoneturn it into a complete navigator.
Among the wired methods of information transfer, we can distinguish MicroUSB (allows a smartphone to fully communicate with a PC) and a 3.5 mm audio port for external acoustics (in this case, a wired connection is implied).
Smartphone price
Now about one of the key advantages that the Samsung SM-G355H smartphone boasts against its competitors. Galaxy Core2 DUOS is currently priced at $100, which is a very good indicator for a device based on a 4-core CPU with a display diagonal of 4.5 inches and good autonomy. Add to this the impeccable build quality, proprietary software add-on from Samsung, and we get one of the best deals in the entry-level gadget segment.
Opinion of owners
Now about what the use of Samsung Galaxy Core 2 DUOS gives in practice. Prices, descriptions and reviews indicate that the South Korean giant has got another good phone in the segment of budget class devices. According to the owners, this is a good and reliable entry-level smartphone. It has everything you need to get the job done and handles most tasks today without any problems. And more is not required of him - this is exactly what both users of the device and specialists agree on.
Of course, certain complaints about the amount of RAM, processor performance andcamera qualities arise from the owners of the Samsung Galaxy Core 2 Duos smartphone. But, on the other hand, the cost of this device is currently only $ 100 - this is an entry-level gadget. Therefore, as users note, the disadvantages against the background of a low price do not seem so significant. The owners agree that this is one of the best deals in its niche.
