Facebook Lite is the app designed by facebook itself for those who wants fast processing on mobile for facebook
First the design of the app is very good with light in weight it does not take very much space in your phone while we install it.
Now the concept is too impressive it works very well aa compared to site and other facebook app.Your phone too does not get hnaged at all or reboot too as we face this problem while using facebook site on phone.
Now with quick processing it saves your mobile data too and loads the pics or videos very fast and helps to see the pics in quick time to save your time and data too.
