How to use Facebook Chat without Messenger on Android

Is Facebook App And Messenger are making your smartphone slow or laggy??As we all know that Facebook forces their users to install messenger for chat which makes our smartphones slow and uses so much memory. I have found a post on xda forums by which we can use Facebook Chat within the App which means we dont need to install messenger for chat. 

IF YOU NEED VOIP CALLS, THIS SOLUTION IS NOT SUITABLE FOR YOU! INSTALL FACEBOOK 55.0.0.18.66 OR AN EARLIER VERSION AND MESSENGER 1.0. IF YOU WANT FACEBOOK'S LATEST FEATURES AND CALLS TOO, EITHER USE MESSENGER OR FACEBOOK HELLO DIALER.

FEATURES

● Send messages directly from the main Facebook app without the need to install Messenger.
● Send images and videos from your gallery or using Messenger's QuickCam feature.
● Edit images and cut videos before sending them.
● Share images from conversations to Facebook.
● Record and send audio clips.
● Send events and locations.
● Send emojis, stickers and big likes.
● See cool snow fall and floating hearts when sending the appropriate emojis.
● Play Messenger's basketball game (without score submission though).

You can download or patch the facebook yourself over here.
