Facebook Chat Enabler

CREDITS TO: AntaresOne from XDA

Root isn't needed and works between Android 2.3 and latest 5.0, on any device that supports Facebook app.

Disadvantages of Facebook+Messenger installed at same time: HUGE battery drain and RAM consumption, device may slow down etc. (especially low-end devices)

Advantages of Facebook Chat Enabler: It's only an enabler and is never executed by the system, meaning no battery drain/RAM consumption/resource eating at all. (Facebook app itself drains battery)

If you have Messenger installed, uninstall it before installing my apk. After installation you don't need to do anything else, no icon is showed in menu and chat will magically work!

New updates of Facebook app in future may break this!!!
