How much does a Samsung Galaxy Core 2 cost? Various sensors perform various quantitative measurements and convert physical indicators into signals that a mobile device recognizes

TFT IPS- High quality liquid crystal matrix. It has wide viewing angles, one of the best indicators of color rendering quality and contrast among all those used in the production of displays for portable equipment.
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.

Terrible battery (or the controller in the phone) - even with the original one, it suddenly begins to lose charge after six months of use. It's even worse with Chinese batteries from Ali. At the same time, there is experience in parallel use of the S3 mini, in the same activity mode - the battery there is still original, but on this phone a whole generation of batteries has already been replaced.

1 Very little RAM and ROM; 2 Has the property of heating up; 3 Price-quality; 4 Poor connection (I'm going to Kazan, but the phone doesn't see the connection completely. I rebooted, took out the battery. Found a connection after 3 hours) 5 Firmware... Many more minuses

After a year of use, the connector for the second SIM card stopped working. An error often occurs when taking photographs. VERY OFTEN the phone, living its own life, turns off and turns on whenever it wants. And it doesn’t matter at all what you’re doing at that moment: whether you’re reading a book in an app or something else.

Not enough RAM. Not enough built-in memory. No possibility of installing on a flash drive. And a weak front camera.

After several months, the charging socket became loose - the original charger stopped charging, I picked up another cord, charged it with it for about a year, then not a single cord would charge at all. During the repair, they could not replace the charging socket, because... the phone is disassembled "Through the face" - i.e. by removing the touchscreen and screen. The touchscreen began to glitch - it opens and closes applications, throws them out and goes wherever it wants (not a virus for sure). Very little memory. All applications are automatically downloaded to the phone's memory and then it does not always allow them to be transferred to the memory card. In general, a problem often arises when downloading and installing applications; some errors constantly appear. In general, a misunderstanding, not a phone.

Memory. A total of 768 RAM and 4 GB of storage, of which more than two are occupied by the operating system and Google services. There is a MicroSD slot, but you can’t transfer anything from a smartphone without root to a memory card. As a result, memory is catastrophically small and not enough for anything. CPU. Not even Mediatek, but the ultra-budget and weak Spreadtrum. GPS. I didn’t check it because there is no memory for cards. Pre-installed applications from Samsung, which (sic!) are not supported on this smartphone. The battery is not enough for a day, even in energy-saving mode, the charge melts right before our eyes. Shiny edging around the edges that quickly peeled off.

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 state employee. Moreover, the screen of the Samsung Galaxy Core 2 Duos is not that big. 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 don't turn out 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.

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 mail and social networks, watching videos - its capabilities are more than enough.

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 the 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
