Excessive "sponsored ads" in FB Lite on one of two tablets
The major benefit of the Android OS is that, usually, there are more than just one app to accomplish a certain task.

This is also the case with Metal for Facebook, a wrapper for the site, giving the user the possibility to avoid both the official Facebook app and FB Messenger as well, for it resembles the way the site looked when visited by a mobile device, before its company's enforcing of the Messenger app, thus allowing a lightweight, all-in-one experience.

I'm in no way affiliated with the developer of this application.
