Keyboard issue on android


I run into an issue with ionic on android. When an input is focused, the keyboard appears while the tabs shows on top of the keyboard, the page will not scroll to show the input element. The page can scroll to the input only when i start to type.
The thing is that if i need to delete sth, the page will never scroll, so that i can’t see what i’m deleting.

Any idea about this issue? Many thanks.
