Android 4.1, or “Jelly Bean” as it’s nicknamed, is not an update full of showstopping features. You can gather that much from the version number, in which only the decimal has changed.
But don’t be fooled; Jelly Bean is arguably the most important new version in Android history.
More than ever, Google understands what it has to do to make Android a top-notch phone and tablet operating system for ordinary consumers, not just tech-savvy users. Instead of just piling on more features with Android 4.1, Google is focused on usability.
