Facebook messenger is great app for using and chatting with fb friend. they first starting cheat head pop up but still havent did good on this way an after so many apps owned this technology and did a great work.
we all facebook messenger is madentory when you used facebook app. but on adroid this app havent get good responce, even the play store have only 3 star, its because this app is sometime so much slow
and even you will see msg on real site then after its comes on messanger 5 to 10 second late.
pop up forgot to remind you that somebody did the msg.
if you got a girlfriend this app will kill you sometime
and you send the msg it wont appear at real time
so its need to work in this app
and also everyday I m seeing update of massenger with same update, nothing is new inside thats peculier.
