Welcome to Android Central, and sorry for the delay! Are you using the main Facebook app (i.e., the one here:
https://play.google.com/store/apps/d...katana&hl=en)? Or are you using some preinstalled Facebook app specifically for Asus? The latter is probably some app made by Asus that interfaces with Facebook.
Open the Facebook app, tap the Menu button, and scroll down to App Settings. Then change the Refresh Interval to your preference. Even if it's set to Never, you should be able to manually refresh by swiping down on your newsfeed.
