Google app for Android will soon add new features to edit and share screenshots
Selecting edit will open up a simple editor that allows the user to crop the screenshot, and draw doodles on it. There are seven colors that can be used to draw, highlight, or cover up part of the screenshot. When finished, the user taps the check mark found below the image. This saves it in your phone's Screenshot folder, and calls up the share menu.
Version 7.21 of the Google app for Android should start rolling out soon. You can try out the new features right now by signing up to be a beta tester for the Google app. Simply go to the Google Play Store, click on the hamburger menu at top in the search bar, and click on My apps & games. Scroll down to Google and tap on the listing. When the listing appears, scroll to the bottom and you should see a prompt pop up asking if you want to join the beta program.
