title: Ionic 2/3 WhatsApp like messenger functionality
body: <p>I'm trying to implement a WhatsApp like messenger functionality with Ionic 3 using JavaScript, and ran into troubles with the keyboard. When I click on the input text area, the keyboard will move the whole App by the amount the keyboard opens. If I use the following code to disable scroll functionality, then my input text area field gets hidden behind the keyboard. </p>
  
  <p>What I want is to disable the Scroll but have the input text area move up together with the Keyboard. Does anyone know how to cleverly solve this problem? Many thanks!!</p>

            ios : {
              scrollAssist: false,  
              autoFocusAssist: false 
            }
          }
        }
