You can use additional applications for screenshots which are very much in Google Play: Screenshot Pro, Private Screenshots, Screenshot touch, Screenshot Easy, Screen Master and more... They all have instructions on how to use them to make a screenshot and save the picture.
How can I share my screenshots? Depending on the Android version and the built-in shell, 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 select the appropriate icon for sharing. Or just open the gallery app on your tablet.
Where are my screenshots? If you can't find the screenshots you took, don't lose heart. 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.
This is suitable for tablets of all operators.
