Google keeps updating with its new ideas and innovations to improve their services.Now Google has made a new chat app named "hangouts"
. So this hangout allows you to connect through your friends on Google plus and the contacts that you have saved in your phone or also you can contact them through their email.It is not an ordinary chat messenger because you can not only chat but also video chat with your friends.
If you install it,your Google Talk will be replaced by it and it worth installing,its far better than the old talk.
It comes with a nice interface , to select a friend for chat you have to slide from right to left or you can click the plus icon .
