Screen type: IPS (In Plane Switching) is a high-quality liquid crystal matrix that was created to eliminate the main disadvantages of matrices based on TN technology. IPS-matrix in the entire spectrum most adequately reproduces colors at different angles of view, with the exception of some positions of colors. TN-matrix has, as it were, a better response than IPS, but not always. So, when transitioning from gray to gray, the IPS matrix behaves better. This matrix is also resistant to pressure. Touching the TN- or VA-matrix results in "thumping" or a certain reaction on the screen. An IPS matrix does not have a similar effect. In addition, ophthalmologists confirm that the IPS matrix is the most comfortable for the eyes. So *Ё *m*ow way, the IPS-matrix brings a bright and clear picture regardless of the angle of view, the best for working on the Internet, watching movies. But most importantly - for image processing and viewing photos. LCD (Liquid Crystal Display) - Liquid crystal displays. The very first displays used in mobile devices, and not only in phones. Their main feature is that they have very low power consumption, due to the inability to display a color image. They do not emit light and therefore phones are upgraded with backlight lamps. Some phones had several different backlight colors based on the presence of different LEDs around the perimeter of the display. This extraordinary solution was used, for example, in Ericsson phone A3618. Pixels are clearly visible on this type of display, and such displays cannot boast of high resolution. In order to prolong the life of such displays, they made them inverted, i.e. text and symbols were displayed not as filled pixels, but, on the contrary, inactive against the background of filled ones. Thus, the light text on a dark background turned out. Currently, this type of display is used in the cheapest budget models (Nokia 1112) and as an external display in some flip phones (Samsung D830).

TFT (Thin Film Transistor) - Liquid crystal displays based on active matrix thin film transistors. For each pixel there are three transistors corresponding to three colors (RGB - red, green, blue). On this moment, these are the most common displays that have a number of advantages over other displays. They are characterized by a minimum response time and rapid development - ever-increasing resolution and number of colors. These displays are most common in mid-range phones and above. Working resolutions for them: 128x160, 132x176, 176x208, 176x220, 240x320 and others less common. Examples: Nokia N73 (240x320, 262k colors), Sony Ericsson K750i (176x220, 262k colors), Samsung D900 (240x320, 262k colors). TFTs are very rarely used as external clamshell displays.

CSTN (Color Super Twisted Nematic) - Color liquid crystal displays with a passive matrix. Each pixel of such a display consists of three combined pixels, which correspond to three colors (RGB). Some time ago, almost all phones with color displays were based on this type. And now the lot of such displays is budget models. The main disadvantage of such displays is their slowness. The undoubted advantage of such displays is their cost, which is much lower than TFT. Based on simple logic, we can assume that in the future TFT will displace this type of display from the mobile device market. The evolution of the color of such displays is quite extensive: from 16 to 65536 colors. Examples: Motorola V177 (128x160, 65k colors), Sony Ericsson J100i (96x64, 65k colors), Nokia 2310 (96x68, 65k colors).

UFB (Ultra Fine and Bright) - Liquid crystal displays with increased brightness and contrast on a passive matrix. We can say that this is an intermediate option between CSTN and TFT. This type of display boasts lower power consumption compared to TFT. For the most part, such displays were used by Samsung in mid-range phones. This type displays are not widely used. Examples: Samsung C100/110 (128x128, 65k colors).

TN is one type of TFT screen matrix. Roughly speaking, TN are the simplest and cheapest TFT matrices. The viewing angles are the narrowest.

LTE LTE (Long Term Evolution) is defined as fourth generation (4G) technology. It is developed by 3GPP based on GSM/EDGE and UMTS/HSPA to increase the capacity and speed of wireless mobile networks. The subsequent development of technologies is called LTE Advanced.	LTE 800 MHz LTE 900 MHz LTE 1800 MHz LTE 2100 MHz LTE 2600 MHz

With some processors, this search is performed simultaneously in L1 and L2.	32 kB + 32 kB (kilobytes)
Second level cache (L2) L2 (level 2) cache is slower than L1, but in return it has a larger capacity, allowing more data to be cached. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for it in the L3 cache (if available) or RAM.	512 kB (kilobytes) 0.5 MB (megabytes)

Accelerometer(or G-sensor) - device position sensor in space. As a main function, the accelerometer is used to automatically change the orientation of the image on the display (vertical or horizontal). Also, the G-sensor is used as a pedometer, it can be controlled by various functions of the device by turning or shaking.
Gyroscope- a sensor that measures the angles of rotation relative to a fixed coordinate system. Able to measure rotation angles in several planes simultaneously. The gyroscope together with the accelerometer allows you to determine the position of the device in space with high accuracy. In devices that use only accelerometers, 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- sensor, thanks to which the optimal values of brightness and contrast are set for given level illumination. The presence of the sensor allows you to increase the operating time of the device from the 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 pressing. The presence of the sensor allows you to increase the operating time of the device from the battery.
Geomagnetic sensor- a sensor for determining the direction of the world in 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 mapping programs for orientation in the area.
Atmospheric pressure sensor- sensor for accurate measurement of atmospheric pressure. Is a part GPS systems, allows you to determine the height above sea level and speed up positioning.
touch ID- Fingerprint identification sensor.

Satellite navigation:

GPS(Global Positioning System - global system positioning) - satellite system navigation that measures distance, time, speed and determines the location of objects anywhere on the Earth. The system was developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine the location by measuring the distances to the object from points with known coordinates - satellites. The distance is calculated from the signal propagation delay time from sending it by the satellite to receiving it 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 measurement principle is similar to the American GPS navigation system. GLONASS is intended for operational navigation and time support for ground, sea, air and space-based users. The main difference from the GPS system is that the GLONASS satellites in their orbital movement do not have resonance (synchronism) with the Earth's rotation, which provides them with greater stability.

General characteristics

Type

Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to stop the choice on the phone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.
