Facebook is very comman app in all android phones . All age of people is join in facebook . Facebook is used to make friend and talk to friend . Friend who is in abroad you miss him so open facebook and start cheating . Concept is pretty cool . I love you mark zukerberg. Design is also attractive I love it. It’s useful and not because it is useful to keep friend close and not is its waste of time. But there my account also in facebook. Thankyou for reading my review. I suggest to install facebook try if you enjoy so keep this app if not then uninstall.
