Regarding screenshots, here's a detailed description here. Even specifically, on which models how to take a screenshot .: https://programmydlyacompa.ru/kak-sdelat-skrinshot-ekrana-na-android/
Using the buttons
On gadgets with Android OS version above 4.0, you can take a screenshot with one button, sometimes two. Keyboard shortcuts may differ depending on the models of mobile devices.
The article from the section https://deviseblog.ru/lifehacks/ tells in detail about different ways to take a screenshot.
The screenshot function is enabled differently on different Android smartphones. But for most, you can unfold the top curtain and there will be a "Take a screenshot" window as well as a combination of the home button and volume up / down. There are more ways here https://4gltee.ru/kak-sdelat-skrinshot-na-samsunge-a10/
The basic combination common to all Android smartphones is power button plus volume down . This sends the captured screenshot to the Photos folder. Different brands may have additional combinations.
The advantage of this method is its simplicity, but it is better to have an installed screen. More than half of the time a screenshot is taken, the point of a screenshot is to explain or demonstrate something to someone. Screenshot applications, firstly, allow screen sharing without unnecessary complications, which is invaluable when you have to perform this operation many times in a row, and secondly, they have a built-in editor .
With its help, you can underline something on the screen, highlight something with a rectangle or an arrow, or, on the contrary, cover up some personal data.
A selection of applications for creating screenshots with links to download from Google Play can be found here .
Very simple! You need to hold down the key combination, for example on Xiaomi you need to hold down the volume key and the power button. You can also just swipe 3 fingers across the screen.

I join the answers of my colleagues, but I note that not all methods are presented in the thread. For example, on most Samsung smartphones, a key combination is used to take screenshots: Home + Power / Lock button. Only on the latest frameless models, the combination of the volume down key and the power button is responsible for taking screenshots.
Moreover, in many modern firmware, the "Screenshot" function is available by means of the system. It is enough to open the quick settings panel (the so-called "shutter") and click on the item of the same name. This option is available in MIUI firmware on Xiaomi smartphones and in EMUI on Huawei phones.
On devices running stock Android 9 (or newer), the "Screenshot" touch button is located in the menu, which Thoroe pops up when you long press the lock button.
But this is not all. There are special applications for capturing images from the screen, for each of which there are specific application scenarios. I talked about them in detail in a separate article.
You can also create screenshots using the ADB utility by connecting your mobile device to your computer via USB. I talked about using ADB in another manual.
If you don't want to download and install special applications, you can use the standard tools.
Both methods are borrowed from the help article. The original source is available here. There is also a detailed description.
All phones based on Android support taking screenshots by simultaneously pressing two keys - "Volume down" and "On / Off".
The picture below shows them.
After that, the file will be located in the "Photos" folder.
In the latest models of smartphones on Android, this option has been added to the drop-down menu. Try swiping your finger from top to bottom of the screen. If there is a "Screenshot" item in the menu that appears, you can use it. The principle is the same.
To take a screenshot on your phone, it is usually enough to press the volume down and off buttons at the same time, or the off button and the "Home" button.
