Samsung has had a rich screenshot editor in TouchWiz for years, and Apple has even added a similar feature to iOS 11. So far, Android has lagged behind in this area, but that's finally fixed in Android 9.0 Pie.
Screenshot editing in Android Pie is actually pretty intuitive. Just start with a screenshot as you normally would. For most phones (including Pixel and Nexus devices), it is sufficient to hold down the volume for one or two seconds at a time and press the power buttons at the same time.
Once you've taken your screenshot, you'll see a new button on the heads up-style notification – it's called "Edit." Just tap on this "edit" button and you will be immediately redirected to a menu where you can edit the screenshot.
You can move the borders to trim the screenshot, and there is a pen tool and a highlighter. If you select one of the latter, you can choose the color you want to draw with. There is no tool to place stickers or arrows on your screenshot, but it's a lot better than what we worked with (nothing).
When you're done editing, either tap "Save," to save a copy of the edited screenshot on your phone, or to "Share" to send a compatible file
