Keyboard Covering a login button

Hello everyone, i am having an issue with ionic3 keyboard, I have a div that contains input field and a button to confirm the value of the input field, when ever I tap on the input and the keyboard shows up, the keyboard cover some part of the proceed button, what I want is for the the button to adjust up a bit for the users to be able to proceed with out having to scroll the page up. this issue vary from device to device, which means some device will display it well and for small screen device it will not show, thank you all.

The only solution for this problem is adding margin bottom of 50px to your login div container.
