Thats what bothers me the most about my Samsung phone. Facebook came preinstalled and I cannot uninstall it. I can only deactivate (whatever that means).

I don't use facebook, I actually never did. Its not the fact that I'm loosing a few MBs of storage that really bothers me, it's the fact that this is the facebook app.

You can uninstall it using ADB, even without rooting. Not a consumer-friendly solution but I’m throwing that out there in case you want to try it.

I think I'll try that. I guess that'll work for LinkedIn/Office as well? However, not sure if the BYOD policy will like that.

I don't have it on my phone and I don't see a reason for a native app for facebook. The mobile website works good enough if I need to check something (sadly it's heavily used also by companies and newspapers in my country) and messenger works through https://mbasic.facebook.com/messages/
