As you can see last week, the Flipboard app appeared during the launch of the Galaxy S III and should keep its exclusivity with Samsung for a few months.
But today, with the help of developers from the XDA forum, the app has been extracted from the device and is available to anyone interested in downloading and installing the APK outside the Google store, Google Play.
To install the application, you need to disable the security option that prevents Android from installing unknown applications.
After installation, be sure to activate the lock again.
