iOS Home Button
Helps to modify the iOS home button parameters for each new scene or canvas on awake, you may consider add just one instance per scene.
Hide Home Button: You can hide the home button while no touches are over the screen.
Use Padding: Adds a black frame to the bottom over the space of the home button with bazel at the corners to simulate the iPad Pro's bazel.
Attenuate Home Button: In my opinion the sexiest way to deal with iOS Home Button for a game in Unity.
