Messenger, aka Facebook Messenger, is a free app you can use to send instant messages to your Facebook friends and people in your Android phone’s contacts. Create groups, name them, set group photos and keep them all in one place and enjoy group chats. Have fun expressing yourself with emoticons and funny stickers and keep the conversation alive. You can even shoot videos and take photos and selfies in other apps (like Instagram) and send them directly to Messenger. You can also use Messenger to make free calls over Wi-Fi.
