Samsung galaxy core 2 specifications. Information about the brand, model and alternative names of a specific device, if any

TFT IPS- High quality liquid crystal matrix. Has wide viewing angles, one of the best indicators of color and contrast quality among all that are used in the production of displays for portable equipment.
Super AMOLED- if a conventional 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 a brighter screen for the same power consumption.
Super AMOLED HD- differs from Super AMOLED in high resolution, thanks to which it is possible to achieve a size of 1280x720 pixels on the screen of a mobile phone.
Super AMOLED plus- this is a new generation of Super AMOLED displays, different from the previous use more subpixels in a conventional RGB matrix. The new displays are 18% thinner and brighter than the older 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 wider color gamut, smaller thickness and the ability of the display to bend slightly without the risk of breaking.
Retina-display with high pixel density, designed specifically for Apple technology. Pixel density per Retina displays is such that individual pixels are indistinguishable to the eye at the normal distance from the screen. This provides the highest picture detail and dramatically improves the overall viewing experience.
Super Retina HD- the display is made using OLED technology. The pixel density is 458 PPI, the contrast ratio reaches 1,000,000: 1. The display has a wide color gamut and unrivaled color accuracy. Pixels in the corners of the display are anti-aliased at the sub-pixel level, so the edges are smooth and look smooth. 50% thicker Super Retina HD gain layer. It will be harder to break the screen.
Super LCD is the next generation of LCD technology and features improved performance over earlier LCD displays. Screens have more than wide angles review and better color reproduction, but also lower power consumption.
TFT- A common type of liquid crystal displays. With an active matrix controlled by TFTs, display performance is significantly improved, as well as contrast and image clarity.
OLED- organic electroluminescent display. Consists of a special thin-film polymer that emits light under the action of an electric field. This type of display has a large margin of brightness and consumes very little power.

Great model

Advantages of the phone Screen, decent speed, modern OS, price and everything else. Disadvantages of the phone: Not always reliable reception

A comment about the phone:

I think I will not be mistaken if I say that the phone has no alternative for its money at the moment. I have been using it for almost a month.
A completely modern model, although it contains some compromises. so, there are no light and talk sensors, a small amount of RAM and hard memory for 2014 (although I had the same on my PC about seven years ago).
In general, it works quickly and smoothly, all applications start and run without problems.
The downside is, perhaps, periodic difficulties with reception when 2 SIM cards are installed. When one - there are no problems, when 2 - can lose and re-find the network a couple of times a day. And also, it does not always quickly turn on when Yandex Navigator is turned on: either GPS is looking for a long time, or the mobile network is catching poorly - therefore, it is easier to reboot.
Reboots very quickly. Within 20-30 seconds, after which everything is usually ready to go, although perhaps this is because I have not yet had time to properly dirtied it :)
In general, who needs a decent modern smartphone for a reasonable price, slightly exceeding " Chinese counterparts"- buy, you will be satisfied.

Review # 2 about the phone Samsung Galaxy Core 2 Duos SM-G355H / DS

Great model

Phone experience: less than a month

Phone Advantages Fast, powerful. Although the screen is TN, it is bright like IPS in 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 is automatically locked when you start talking. But for the convenience of completing a call in special features, I installed hang up the phone on the on / off key, and you do not need to poke your finger at the screen to unlock and then hang up
No film on the screen
There are no pictures for the background
I don’t understand how to put widgets
