Use buttons
To take a screenshot is to use the buttons. Press the Volume Down and Power buttons and hold them down until you save a screenshot. You can also use this method to make a scroll screenshot.

If the main way to take a screenshot not work and you can't find image let's go further.

Another option is to use phone features capabilities. Swipe down on the screen and open the notification bar. Locate the screenshot icon (shortcut) and tap on it to take a picture. You've done all you want to do. You got the picture.
Use apps
You can use special apps for screenshots which are very much in Google Play: Private Screenshots, Screen Master, Screenshot touch, Screenshot Easy, Screenshot Pro etc... All these apps have instructions on how to use them to take a screenshot and save the picture.
Google Assistant
The laziest option is to use Google Assistant. Just say OK Google and then Take a screenshot. The phone will do everything for you.
How do I share my screenshots? Depending on the Android version and the custom UI, sending screenshots may differ. In lastest versions of Android (9 or 10), the smart menu will arise after you take a screenshot instantly. There you need to select the appropriate icon for sharing. Or just open the gallery app on your phone.
Where do my screenshots go on? If you can't find the screenshots you took, don't give up. The folders where the gadget saves screenshots and usual photo may be different. Again, it all depends on custom shells. A pure Android throws pictures into the gallery (DCIM). Other shells can save screenshots to a separate folder for your convenience.
This is suitable for phones of all operators.
