How do 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 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 gadget.
Where do I find the screenshots I've taken? If you can't find the screenshots you took, don't lose heart. 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 separate folder for your convenience.
These methods work with gadgets of all operators.
