Facebook is one of the biggest social site in the world but this app is totally irritating app. Through this app you can connect with your friend and login your Facebook account and see your notifications.But, I don’t like this app because this app is very big in size and after downloading this app the phone starts crashing and in this app you don’t have messenger option which is a backward point of this app. Facebook lite in which messenger option is available as a smaller app in size than Facebook.The layout and design of the app is very good but sometimes it crashes a lot and it is a very slow app.It takes too much time to open . Facebook is a very useful site but this app is not useful at all.
