Facebook messenger has been evolving for some time now, first we had chat heads which let you access your messages from anywhere. Facebook recently updated the app to allow you to take a selfie and send it to your friends. Now with another update, Facebook Messenger for iOS and Android allows you to record and send 15-seconds videos from within the app itself.
Its quite similar to Snapchat to be honest. You just tap on the camera icon then keep the send button pressed till you record what you want to send and then release the send button. Your video is on its way. You can download Facebook Messenger from the links below.
