Hi there, Facebook came up with a new feature called Facebook touch. It is the same app but with different features. Facebook launched it for the purpose to make it more convenient, user-friendliness, and saving battery and space consumption. It is very easy to access it. Below, I have given step by step process of it.
Search for touch.facebook.com
Put your linked Facebook account number and email
After that write password
Then final click on the login button
