Facebook is the one the biggest social networking website at this time, I am using facebook account from past 5 years and I am satisfied with the facebook, after that I just found the new Facebook Messenger application for android mobile phones.
Ater that I just install it in my android mobile phone and then login with my facebook account, after that I use my account, but this will take so many time for loading and some times it gone be hang my phone, I think facebook should improve this application otherwise the concept is so nice of Facebook Messenger.
