Whether it’s a new chat request, visitor, response or other event, the app allows you to receive both sound and vibrate notifications on your Android devices.
Using pre-defined messages and URLs — which are easily accessible from the Android chat app — you can answer relevant questions with a single tap.
This saves you repetitive typing and improves chat efficiency considerably.
The reason that Facebook Messenger is perhaps the best choice on this list is the fact that you probably already have it, and most of your friends do too. Simply open up the app, press on the person you want to call, and tap the camera button in the top-right corner.
The app will then connect you with your friend, and you’ll be able to chat the same way you would in any other video chat app.
In i OS 10 you can add those favorites as a widget and start a Face Time call from your lock screen.
