How do I share my screenshots? Depending on the Android version and the built-in shell, sending screenshots may differ. In new versions of Android (9 or 10), the quick actions menu will arise 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 can I find screenshots I made? If you can't find the screenshots you made, 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 different folder for your usability.
This is suitable for phones of all operators.
