If you are having Facebook app on your Android phone and are frustrated after the recent updates because you can't refresh your news feed, open any page or profile and the app keeps on saying Can't connect right now Retry.
Well then here is a solution for you.(It worked for me.)
Drag the Facebook app icon from the app drawer to top of the screen where it says App Info.
Just click on force stop and now open the Facebook app.
Wolla now you are happy to go....
Hope this works for you....
