Google Assistant
The laziest way is to use Google Assistant. Just say OK Google and then Take a screenshot. The phone will do all the work for you. How can 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 quick actions 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 gadget.
Where are screenshots saved? If you can't find the screenshots you made, don't give up. The folders where the gadget saves screenshots and ordinary 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 comfort.
This is suitable for phones of all operators.
