Samsung does a pretty good job of partnering with companies to line their pockets for adding forced bloat to your phone. They have had a long standing partnership with Flipboard to integrate the Flipboard Briefing screen to your homescreen. The screen is enabled by default and swiping to the right brings up the news feed for viewing.
The screen doesn't really cause any lag or hiccups on the homescreen, but it does add a bit of clutter. Thankfully Samsung has made it very easy to disable this bloat and free up the screen. Just swipe over to the screen, pinch the screen to bring up the homescreen settings, and then toggle the screen off.
