World largest Social Site is Facebook. I used Facebook app and also Facebook Lite app but Facebook app in totaly useless than Facebook Lite. I noticed that in My mobile Facebook app block a huge storage. When I installed it it was just 30mb apk file but now it was 130 mb apk file. It so pathetic. Besides it open very slow in my mobile. Most problem in this app is it has no option for Chatting . If I want to chat with my friends then I need to install Facebook messenger also. But If I installed Facebook lite it take only 5 mb and give me all options but Facebook app and Facebook messenger app take 200mb to give me all options. That’s why I don’t recommend it. Its not a user friendly app. That’s my opinion. So I think it is not useful for daily facebook user.
