Hello friends, I’m starting to develop a section related to smartphones, now it’s fully operational. Now on the site you will find a bunch of interesting articles about Android smartphones. I will try to convey to users in as much detail as possible about new smartphones, that is, there will be a lot of news. Of course, I will focus on creating materials on working with the OS. So to speak, instructions from A to Z. For now, I’ll start with the simplest thing and write an article about what it is and what its advantages and disadvantages are. Now let's get to the point.
What is Android OS
Android is an operating system based on the Linux kernel, which was purchased by Google in 2005. In 2008, the first version of the operating system was released. This OS is designed for smartphones, tablets and many other devices. At the moment, it is built into watches, various navigators, set-top boxes and players.
Now a huge number of smartphones and other devices with this system are being created. It has gained tremendous popularity, so it has almost no competitors, except perhaps iOS.
I think it’s not worth listing the well-known brands of today’s phones, which are growing by leaps and bounds. So, they all use Android. If we talk about a pure system, we can say that it is very fast and productive. Many manufacturers, using this OS as a basis, create their own shell with additional functions, capabilities and design. Some people do this better, and the system flies, but in some devices it’s not so good.
Using the operating system, you have the opportunity to control functions such as Wi-Fi, Bluetooth, NFC, GPS, create Wi-Fi access points, that is, turn your phone into a modem and much more. Modern smartphones are equipped with fingerprint and iris scanning sensors, which can greatly improve protection - all of this can be controlled using Android. Naturally, Apple with its iOS is trying to keep up.
Which smartphone to buy on Android in 2022
It is better to buy a smartphone with Android in the latest generation. Then it will work for you for another 2-3 years without lags. We recommend choosing new products from market leaders.
Samsung introduced a new product in the expensive segment S21. This smartphone is compared to the iPhone 12. However, it costs 10 thousand less. Therefore, if you want a top-end flagship for Android, then choose this option.
You can get cheaper Mi 11 from Xiaomi. All technical settings have been updated here: 108 megapixel camera, fast charging, high performance with the new Qualcomm Snapdragon 888. And all this for 65 thousand rubles.
For budget models, we recommend Realmi 7 Pro. It also has strong performance, fast charging and a good camera. Allows you to take up time if you are bored in classes. Therefore, for 24 thousand - this is the best that you will find on the market in the first half of 2022.
Advantages and disadvantages
Let's look at the advantages and disadvantages:
- Since it is developed on the open source Linux kernel, the mobile system is also open source, which allows you to create whatever your heart desires for this system.
- The clean OS is highly optimized and is not demanding on devices. It can work on the weakest phone that is currently available, although this is already rare.
- The ability to customize the system for yourself.
- A huge number of add-ons and applications that greatly expand the capabilities of the OS.
- Speed of operation (not in all cases).
- The system is available for the following hardware platforms: ARM, x86, MIPS.
These are the main positive characteristics that I noted for myself. Maybe there is something else. In addition to the advantages, there are also disadvantages:
- An open-source operating system gives manufacturers of smartphones and tablets an advantage to create shells that are not always as optimized and efficient as possible. In addition, the shell update may come much later than the latest version of the official system is released.
- If the system is poorly optimized, then there is a possibility of high energy consumption. And atomicity is now highly valued. But it depends rather on the device manufacturers.
- Because of its popularity, hackers and other bad people write viruses for the OS and look for vulnerabilities. Of course, this OS has certain protection, not like Windows. Therefore, the disadvantage is insignificant.
- There have been cases where several million dollars in total have been stolen from users around the world. This was done by sending SMS without the user’s knowledge.
Why people buy Android
So, in order to figure out which is better - Android or iOS, you need to understand why you are buying the first option.
Firstly, Android-based smartphones are relatively cheap. They are sold in different price segments: from budget (10-20 thousand rubles) and medium (20-50 thousand) to expensive (from 50 to 100 thousand rubles).
There are more than five companies that produce Android smartphones. New manufacturers appear periodically. Due to high competition, technical indicators may be different in the same price segment.
For example, Realme entered into competition with one of the leaders in smartphone production, Xiaomi. To attract buyers, they lowered the price of top-end smartphone models that were ahead of Xiaomi's flagships.
An Android smartphone allows you to connect to different devices that are not from the same manufacturer. For example, a Korean Samsung smartphone allows you to connect to wireless headphones from AKG, Honor, etc. You can choose headphones from absolutely any company to suit your taste.
So, we will describe in more detail all the pros and cons of Android below.
Types of firmware
In addition to the pure system from Google, there are a number of enthusiasts developing their own firmware, which have their own functionality and capabilities. You will see a completely different design; it happens that the firmware of another manufacturer will work better than pure Android.
At the moment, there are companies that create firmware for smartphones and other devices: CyanogenMod, which is now LineageOS, AOKP, MIUI, Paranoid Android, AOSP, Replicant and others.
Enthusiastic developers try to release firmware versions on time, together with the release of a clean OS. But sometimes there is no need to flash the phone, since the manufacturers could take care of it.
Applications and Play Market
Everyone knows that every day hundreds of programs and games are uploaded to the Google application store - Play Market. You can find whatever your heart desires, these are various audio and video players, desktop wallpapers, file managers, of which there are probably thousands, a lot of software for communicating with people - social networks, instant messengers and others. You can also download movies, books and music from there. Of course, there is content there, both paid and free.
A little theory. The Android application code is written for the so-called Dalvic virtual machine. Applications are in .apk format, this is the only format. Until recently, applications themselves could be written in Java, but since 2009 Google added a special package of capabilities that allows you to create software in C and C++. Also, there are many development environments, such as Embarcadero RAD Studio.
As for the application store itself, it was opened in 2008. The agreement was that the software developers would give 30% of the profits to Google. By the standards of 2022, there are about more than 2.8 million applications in the Play Market database.
Of course, unscrupulous users sometimes posted applications with malicious code, which caused a scandal around 2011, but the problems were quickly hushed up and the vulnerabilities were closed.
No matter what anyone says, the direct specific Play Market is the App Store - an application store for iPhone, iPad, iPod and other devices. They have less software than the Play Market. Developers' income is the same as Google's. You create a paid application for which you will give 30% of the profits.
iOS
pros
- excellent performance
- its own unique ecosystem
- high level of data security
- stable updates for 5 years
- better software optimization, including camera software
Minuses
- small lineup
- significantly inflated price tag
- many good applications - paid
- minimum possibilities for customizing the smartphone
What's inside Android
And now, almost the penultimate point, in which I want to talk about the internal components of the system. Those who use this system should understand it at least a little. And compare it with Windows.
So, Linux differs from Windows in that the latter has information divided into disks and folders, of course, in Linux as well, but it is all displayed differently. Linux systems have a tree structure.
There are also differences in registers. If you create several folders with the same names, then on Windows there will be no difference, but on Linux these will be completely different folders. This also applies to files. These names will be different in Linux - Papka, papka, PAPKA.
The cache for the system and some application will always be saved in a special section - cache.
Surely everyone has seen the data folder in the file manager. This directory has other folders related to installation files and application directories.
Configuration files and software libraries can be found in the app-lib folder.
For applications to work, they are written in Java for a special Dalvik virtual machine. That's why you may come across the dalvic-cache directory. Sometimes it needs to be cleaned, for example, before flashing the phone. This is done using root rights or from the Recovery menu, but I will definitely talk about all this in future articles.
You will definitely see the system directory in the file manager. From the name it is clear that system settings are stored there, changing which can ruin your system.
In the etc directory you will find files that allow the system to start normally.
These are not all the folders that are in the Android system. It will take several additional articles to sort it all out.

So, in this article we looked at 2 systems: Android and IOS. To understand which is better, you need to look at the pros and cons for each OS. Currently, both platforms compete on almost equal terms. If you want more freedom in gadget settings and choice of free applications, then Android is more suitable for you. If you want to use your smartphone safely and have support for years to come, then you need to choose iOS.
Additional features
Many people know that each modification of the system has a key name, usually some kind of dessert. For example, Cupcake, which means cupcake. One of the popular versions 4.1-4.3 is called Jelly Bean. But version 4.4 is named after the famous KitKat chocolate bar. The next modification 5.0 and 5.1 is called Lollipop - lollipop. The sixth option is Marshmallow and, finally, the latest version at the moment, 7.0-7.1.2, received the Nougat code.
There is just a little time left before the release of version 8, or as it is called Android O. The beta version of the operating system is already installed on some flagships and works stably. The entire OS will be released at the end of 2022. And yes, the keyword will most likely be Oreo. Below you will see a video of the presentation of the eighth version.
Well guys, I finished the article, now you know what Android is, where it is used, its features. In future articles I will tell you almost everything related to this operating system. Well, I wish you good luck!
