Facebook launched a Android app called Facebook Lite, which is a version of Facebook built from scratch to work smoothly with poor data connections and low-end phones.In facebook Lite app some times connectivity problem occurs it sometimes works and sometimes does not load. Facebook Lite does not have the same finesse that a full fledged app offers.
it consumes lot of ram memory and battery.It is not easy to access.In background I consumes lots of internet data.
