We've already gone over how to take and share a screenshot on an iPhone. With iOS 12 or later, the screenshot appears in the lower-left corner of the screen for a few seconds.

If you accidentally took the screenshot, you can also immediately delete the image by tapping on it. We'll cover how to mark up screenshots with iOS 13 on your iPhone below.
