My Facebook all has never worked for longer than about a month for me, on any of my last 5 or so Samsung devices. It always crashes whenever I try to open comments or notifications, but it lets me scroll down my news feed for a few minutes.
Weird thing is that my spouse has never had any of these issues and he has the same phone.
Sometimes uninstalling/downgrading and reinstalling or clearing cache and app data will bring the app back to a usable state for a few days, but I just use Facebook mobile on my browser.
