Home offscreen button during typing topic

Is anybody else having this issue? I am coming from Galaxy S4, where the home button is actual physical button, so there I didn't have any issues, but with OPO, when typing, many times when I try to hit spacebar, it hits the top of the Home button. Before it comes up, I do not want to use on screen buttons, I like the size of the screen and don't want it up with software buttons.

I was wondering if anyone has/could write a script to set the buttons to

(Menu)
Short press - Menu
Long Press - Recent Aps

(Home)
Short press - Nothing
Long Press - Home

(Back)
Short Press - back
Long Press - nothing

Or of there is an app that would give me a bit more control over the buttons... or something that can help with this. This is absolutely the only issue I have with the OPO otherwise I love the phone.
