Google is introducing a new way to take screenshots, one that will be accessible to anyone with an Android device that is running Android 6.0 Marshmallow and above. The contextual arm of Google Now, known as Google Now on Tap, now has a dedicated share button to take a screenshot of your display before choosing which app to share it with.
This finally gives every owner of an Android device an identical way to take a screenshot. Before, devices with physical buttons could vary from a combination between the home button, power button, and volume rocker. Now all that needs to be done is Now on Tap’s activation.
