Toffeed

Toffeed is an ultralight, open source Facebook client that lets you manage your Facebook account with an app that takes up less than 1.5 megabytes. For comparison, the official Facebook app takes up more than 30 megabytes (and often takes up even more space when you start to accumulate temporary data).

In Toffeed's configuration options you'll find some very interesting features. One of them, for example, lets you automatically hide all of the content sponsored by Facebook. That's to say, it basically lets you deactivate Facebook's advertising.

Another option lets you chat with your Facebook contacts straight from Toffeed. If you also have Facebook for Messenger installed, however, it's recommended that you deactivate this option in order to use this application.

Toffeed is a good Facebook client for Android whose strong points include it being very lightweight and having an elegant interface. And if that weren't enough, Toffeed (unlike other Facebook clients) requests very few user permissions: only access to location and images.
