After two years in Beta mode, Google is finally releasing Voice Access on the Play Store. The app enables hands-free usage of your smartphone and is mostly designed for people with disabilities who have a hard time to do simple stuff like take a picture or send a text, but is freely downloadable for everyone. The service allows you to navigate through apps, compose and edit text, and talk to Google Assistant. It offers a deeper integration with the OS and the control of apps, allowing you to "tap" buttons with the application itself. You can say "Scroll forward" or "Tap Go Back"...
