Accelerometer(or G-sensor) - sensor of the device's position in space. As a primary function, the accelerometer is used to automatically change the orientation of the display image (vertical or horizontal). Also, the G-sensor is used as a pedometer, it can be controlled various functions devices by turning or shaking.
Gyroscope- a sensor that measures the angles of rotation relative to a fixed coordinate system. Able to measure angles of rotation in several planes at the same time. The gyroscope together with the accelerometer allows you to accurately determine the position of the device in space. In devices using only accelerometers, the measurement accuracy is lower, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- a sensor, thanks to which the optimal values of brightness and contrast for a given illumination level are established. The presence of the sensor allows to increase the operating time of the device from the rechargeable battery.
Proximity sensor- a sensor that detects when the device is close to the face during a call, turns off the backlight and locks the screen, preventing accidental presses. The presence of the sensor allows to increase the operating time of the device from the rechargeable battery.
Geomagnetic sensor- a sensor for determining the side of the world to which the device is directed. Tracks the orientation of the device in space relative to the earth's magnetic poles. The information received from the sensor is used in cartographic programs for orientation on the ground.
Atmospheric pressure sensor- sensor for accurate measurement of atmospheric pressure. It is part of the GPS system that allows you to determine the height above sea level and speed up the location.
Touch ID- fingerprint identification sensor.

Satellite navigation:
Gps(Global Positioning System) - satellite system navigation, which measures distance, time, speed and determines the location of objects anywhere on Earth. The system is designed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine the location by measuring the distance to the object from points with known coordinates - satellites. The distance is calculated from the signal propagation delay time from its sending by the satellite to being received by the GPS receiver antenna.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measuring principle is similar to the American GPS navigation system. GLONASS is intended for operational navigation and time support of land, sea, air and space-based users. The main difference from the GPS system is that the GLONASS satellites in their orbital motion do not have resonance (synchronization) with the Earth's rotation, which provides them with greater stability.

Brief information
Samsung Galaxy Core 2 G355H, the characteristics of which are soberly assessed 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. 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 of the operating system of the "Android" family. This is version 4.4. WITH autonomous work 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, demonstrates to 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 call this model"Brick" is very, very difficult. 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 profit. Back cover has a corrugated 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. There is a grill on top sound speaker, to the right of it is the peephole of the front camera. Under the speaker there is Samsung lettering, 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. Already on board operating system family "Android" version 4.4. Not the most the best way however it is 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 several applications at the same time, but it must 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.
