Use apps
You can use special apps for screenshots which are very much in Google Play: Private Screenshots, Screenshot Pro, Screenshot touch, Screen Master, Screenshot Easy etc... They all have instructions on how to use them to make a screenshot and save the picture.
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 smart menu will arise after you take a screenshot immediately. There you need to choose the appropriate icon for sharing. Or just open the gallery app on your phone.
Where can I find screenshots I made? If you can't find the screenshots you took, don't lose heart. The places 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 separate folder for your convenience. These methods work with gadgets of all operators.
Metro
TracFone
Verizon Wireless
Virgin mobile
Cricket Wireless
