Type: modern mobile communication devices can be divided into two simple type: smartphones and mobile phones Smartphone

Preinstalled OS: preinstalled OS — any smartphone running on a

it is the operating system. The most popular and common is

Google's Android mobile OS – it produces the device a variety of

price ranges for all buyers. Devices running Apple iOS

also attracting a large number of users, but they are less

affordable for the mass buyer. The third most popular mobile OS

is Microsoft Windows Phone/Windows 10, it also has its fans, but

these smartphones are much less common, including for small

the selection of high-quality programs from third party developers. There are other

mobile OS, but they are even less common or obsolete

Android 9.0 (Pie) + MIUI 10

RAM, GB RAM, GB — a versatile option

affect the performance of your smartphone. A large amount of RAM allows you to simultaneously

keep "running" a larger number of programs open in RAM

the app is much faster, which positively affects

user experience. Worth remembering that the same amount of RAM

memory does not mean the same performance – plays an important role

Built-in memory, GB Built-in memory, GB capacity built-in storage

data. Typically, manufacturers specify the capacity of a used memory chip, and

the actual amount of memory available to the user, is always less than claimed.

For example, if the smartphone has 8 GB of internal memory, the user will be

available about 5.5 GB. The difference "eats" operating system and

pre-installed apps

Expansion slot: expansion Slot — ability to install memory card for

the extension of the internal memory

Type SIM card Type SIM card — in mobile phones and smartphones can

to use the SIM card of one of three types. Mini-SIM – in the usual sense

most users map, with dimensions 25х15х0,76 mm. Micro-SIM

(15х12х0 76 mm) – used in most new smartphones. Nano-SIM

(13,3х8. 8x0. 67 mm) – miniature SIM cards used in recent

Apple smart phones and some HTC models, Samsung, Nokia. These SIM cards

differ not only in length and width, but also thickness. Therefore, to replace

the current SIM card to Nano-SIM, it is best to contact the mobile operator

connection

Nano-SIM

The number of SIM-cards: Number of SIM-cards — many models of mobile phones and

smartphone supports simultaneous work of two SIM-cards in standby mode.

The choice of such a device is the ability to separate personal and work calls

use one SIM card for voice communication and the second for fast

mobile Internet or just optimization of communication costs by

the use of multiple operators and different rates

Processor: CPU or SoC (System-on-a-Chip) is the backbone of every smartphone.

Models built on identical platforms, as a rule, are in the same

price range, guarantee a certain level of performance and set

opportunities

Qualcomm Xiaolong 439 + GPU Adreno 505

Number of cores: Number of cores is a universal value that needs

to reflect the performance of the used platform. All

the processors used in modern smartphones, are at least

2-nuclear. In the budget segment includes both 2-and 4-core

smartphones. Medium and high-end equipped with a 4-8-mi nuclear

processors. The difference between them lies in the clock frequency, which may

to work every kernel, type the kernel and integrated graphics.

Users who wish to purchase a truly productive smartphone

you need to pay attention not only on the number of cores, but also on other parameters
