Why are the Facebook feeds on my device not in chronological order?

In Facebook, there are two different ways to display the news feed:

  • Most Recent view shows all the actions your friends are making in real-time. The feed items appear in chronological order.
  • Top News view shows the most popular posts. The more 'Likes' or comments a post gets, the more likely it appears on the Top News feed.

Your device's Facebook client uses the Top News view, which is the default view when using Facebook with a web browser.
