Use buttons
The easiest way to take a screenshot is to use the buttons. Press the Volume Down and Power buttons and keep them pressed until you capture a screenshot. You can also use this method to make a scroll screenshot.

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 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.
Where do my screenshots go on? If you can't find the screenshots you took, don't despair. The folders where the gadget saves screenshots and regular 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 different folder for your usability.
How do I share my screenshots? Depending on the Android version and the custom shell, sending screenshots may differ. In new versions of Android (9 or 10), the smart menu will appear after you take a screenshot instantly. There you need to select the appropriate icon for sharing. Or just open the gallery app on your gadget.
This is suitable for phones of all operators.
