Answer 1

A touchscreen phone for blind people doesn’t sound like a good idea to me 🙂

Android:

1 b) Without building your own custom rom no way to change the functionality of hard buttons globally. You are free to respond to buttons in your app as you like (except for the home button)

2 b) you can play any sounds while your app is running. But same problem here – you are resticted to inside your app.

Edit: Android has some features builtin:
