Can I hang up using a button? When I'm on a phone call nothing is more important than the ability to hang up. If, for whatever reason, I suddenly find myself in an embarrassing situation or interrupted by something important, I must be able to terminate the call.

Currently the only option, that I know of, is a medium sized red button on the touch screen. I think this is deficient for a few reasons:


the touch screen doesn't always behave as you want (too sensitive, or not sensitive enough) - how often do you listen to chat radio shows and the callers are always "accidently" hitting the dial buttons in the middle of conversation
the GUI may be running slowly and be unresponsive


It there a way of mapping a generic button (such as a camera button on the HTC Desire) to perform the hang-up action? Perhaps someone could write such a service!
Settings | Accessibility | Power button ends call


  During a call, pressing Power ends call instead of turning off screen.
