Use buttons
Perhaps the easiest way to take a screenshot is to use the buttons. Simultaneously press the Volume Down and Power buttons and keep them pressed until the screenshot is saved. You can also use this method to make a scrolling screenshot.

If the first way to take a screenshot not work and you can't find picture let's go further.
Long screenshot
To take a long screenshot, just click on the proper icon. You will see this icon after you have taken a ordinary screenshot. This method can also be called to make a scrolling screenshot.
Click to zoom in
Use Capture icon
Another way is to use phone's built-in tools. Swipe down on the screen to open the notification bar. Locate the screenshot icon (shortcut) and tap on it to take a screenshot. Job done. You got the picture.
Use apps
You can use special applications for screenshots which are a lot in Google Play: Private Screenshots, Screenshot Pro, Screenshot touch, Screenshot Easy, Screen Master etc... They all have instructions on how to use them to take a screenshot and save the picture.
Google Assistant
The slothful way is to use Google Assistant. Just say OK Google and then Take a screenshot. The phone will do all the work for you.
Three-finger swipe
Just swipe three fingers down the screen to get a screenshot. The location of swipe is not important. This way is used in ColorOS.
Click to zoom in
Where do I find the screenshots I've taken? If you can't find the screenshots you made, don't despair. The gadget can save screenshots to different places. Again, it all depends on custom shells. A pure Android throws pictures into the gallery (DCIM). Other shells can save screenshots to a different folder for your comfort.
How do I share my screenshots? Depending on the Android version and the built-in shell, sending screenshots may differ. In recent versions of Android (9 or 10), the quick actions 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.
These methods work with gadgets of all operators.
