Facebook an app by Mark Zuckerberg. It is just like vine which is if you start using it, it becomes addictive and it becomes harder and harder day by day for you to leave facebook. Therefore I dont like this app. This apk is of size about 50mb. And it releses its updates regularly. It helps you to stay tuned with your friends. Anytime anywhere and with anyone. Nowerdays it is becoming greatest distraction for teenage kids due to which they cant focus on their studies.features of facebook are awesome but it is not good for us. Their are many fake acounts on facebook which can be used for crimes by criminals. Therefore I adivices you to never get in touch with it
