Endless runner and tilting phone for turning

Hi All

I have attached a few photos and please correct me if I am incorrect or what I am required to do…

Here are my project settings.

Here is where I assume tilting the mobile phone left and right will make my character turn left or right.

Here are my controls to turn corner.

What would I need to do/change so I can use tilt to turn corners with a small dead centre zone in-case you are not holding your phone dead flat?

Thank you for taking the time to read this.
