Where are screenshots saved? If you can't find the screenshots you took, don't despair. The phone can save screenshots to different folders. 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. How can I share my screenshots?
Depending on the Android version and the custom shell, sending screenshots may differ. In new versions of Android (9 or 10), the smart menu will appear after you take a screenshot instantly. There you need to choose the appropriate icon for sharing. Or just open the gallery app on your phone. This is suitable for phones of all operators.
