Facebook Messenger for Android offers just about everything you'd want in a messaging app, with hooks into your Facebook contacts to help you connect with friends.
Multiple ways to add contacts: Messenger automatically connects you to your Facebook friends, and you can add non-Facebook contacts via their mobile phone numbers. When prompted by the app, you have the option of uploading your phone contacts to Facebook or using your phone number to connect with those who are not Facebook friends. You also have the choice of using Messenger as your default SMS app.
Optional encryption: Messenger's Secret Conversations is available on Android and iOS devices to send and receive end-to-end encrypted messages. Group messages and video and voice calls aren't supported. By default, Secret Conversations are not turned on in Messenger; you need to enable the feature to encrypt messages.
Chat with friends: In addition handling text chats, Messenger is loaded with goodies to make your messages more entertaining, including adding stickers and GIFs to chats.
Voice and video: Messengers lets you make free worldwide voice and video calls. After a group chat, Messenger remembers the participants if you want to chat up the same group later.
Play games: Challenge friends to nearly three dozen games, including Space Invaders and Galaga. In a conversation, tap the Game Controller icon, select a game, and tap Play Now to challenge a friend.
More than just chat: Snap photos, capture videos (including ones with Snapchat-like filters and stickers), and record voice messages to share. Tap the dollar sign icon to send and receive money with friends. You can also add chatbots that will help you make travel plans, for example, or see the latest news.
A tight fit: Though Facebook had the good sense to make Messenger its own mobile app instead of yoking it to the Facebook app, Messenger still packs a lot into one app. Remembering where to find some features can be challenging.
Facebook's Messenger packs a lot of goodness into one app, from text, voice, and video chat to classic arcade games. With seemingly everyone on Facebook, Messenger might be the only messaging app you need to keep in touch with family and friends.
Instantly reach the people in your life--for free. Messenger is just like texting, but you don't have to pay for every message (it works with your data plan). Not just for Facebook friends: Message people in your phone book and just enter a phone number to add a new contact. Group chats: Create groups for the people you message most. Name them, set group photos and keep them all in one place. Photos and videos: Shoot videos and snap selfies or other photos right from the app and send them with one tap. Chat heads: Keep the conversation going while you use other apps. Free calls: Talk as long as you want, even with people in other countries. (Calls are free over Wi-Fi. Otherwise, standard data charges apply. ) Even more ways to message: Bring your conversations to life with stickers. Preview your gallery photos and videos without leaving the conversation--then choose the perfect ones to send. Record voice messages when you have more to say. Extra features: Know when people have seen your messages. Forward messages or photos to people who weren't in the conversation. Search for people and groups to quickly get back to them. Turn on location to let people know when you're nearby. See who's available on Messenger and who's active on Facebook. Create shortcuts to get to any conversation right from your home screen. Turn off notifications when you're working, sleeping or just need a break. Stay logged in so you never miss a message.
