Use apps
You can can download and install additional screenshot apps which are very much in Google Play: Private Screenshots, Screenshot Easy, Screenshot Pro, Screen Master, Screenshot touch and more... All these apps have instructions on how to use them to take a screenshot and save the picture.
Three-finger swipe
Swipe three fingers down the screen to get a screenshot. The location of swipe is not crucial. This method is applied in OxygenOS.

Where does my screenshot go on? If you can't find the screenshots you took, don't despair. The gadget can save screenshots to different places. 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.
How do I share my screenshots? Depending on the Android version and the built-in UI, sending screenshots may differ. In new versions of Android (9 or 10), the smart 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 phone.
These methods work with gadgets of all operators.
