Facebook's new instant messenger replaced the use of whatsapp.
As there are so many people who used to prefer facebook more than whatsapp and now they can get all the facilities of whatsapp in their facebook messenger.
Prominent among these features include VOIP calling, stickers, and one-touch navigation to group chat.
However, certain recent functionalities, found in Facebook's standalone iPhone messenger, like 'split screen camera' and 'tap and hold video record' are conspicuous by their absence in the iPad Facebook messenger.However,Android users are enjoying this at a large scale.
By using this messenger people can send voice messages as well as voice call to anyone for free.
