Ionic input keyboard scrolls up contents

Hi there, hope you will be fine. I need some help. I am using ion-textarea in my ionic project and below that I have some buttons. When I build the app and test on android it looks perfect. When I tap on ion-textarea and simply close keyboad without typing anything it works fine but when I tap on ion-textarea and start typing something and then close the keyboard, the content below the ion-textarea scrollls up and does not go down.Here is the screenshot of the error:

Looking forward to see your response, thanks!
