Google Docs on mobile has always been limited. And since the mobile market is demanding for more mobile functions, features, and services these days, Google has decided to update the app by allowing users to easily view and edit a document. Even when you're on the go, you can edit a document you've been working on whether for school or work. The app has been useful for reading and reviewing a document but editing has not always been easy. This time, you can edit the document by tapping twice the blue pencil icon you see on the bottom right of the page.
