I want to share my personal experience about the Facebook app I have this installed and I use it regularly but I don't like this app,
FB is very famous app but you when you download the app app don't use that all the permissions who you use in our website website is better than I don't like and I know that is I don't need the app you can go online to open the site and you can chat but app is not useful
I don't recommend Facebook app to anyone love don't like it.
