Input Box in View while having focus on it

I have issue relating to Input boxes hiding behind the keyboard when keyboard opens up on focus on particular Input.

This is very usual in landscape mode of our application even in portrait mode it happens for some input if user isn’t scroll that much where keyboard positioned.

We are using Ionic 3.7.1 and Angular 4 version.
Please guide if have any workaround or any particular solution.

Thanks.
