Use buttons
Perhaps the easiest way to take a screenshot is to use the buttons. Simultaneously press the Volume Down and Power buttons and hold them down until you capture a screenshot. You can also use the button on the back of the phone, if there is one. You can use this method to make a scrolling screenshot.

Google Assistant
The slothful way is to use Google Assistant. Just say OK Google and then Take a screenshot. The phone will do everything for you. How can I share my screenshots? Depending on the Android version and the custom shell, sending screenshots may differ. In lastest versions of Android (9 or 10), the smart menu will appear after you take a screenshot immediately. There you need to choose the appropriate icon for sharing. Or just open the gallery app on your phone.
Where are screenshots stored? If you can't find the screenshots you made, don't despair. The places 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 usability.
This is suitable for gadgets of all operators.
