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!

Not to mention if you happen to navigate away from the call screen it'll take a couple clicks to get back to where you can hang up. –  Matt Nov 19 '10 at 12:41
    
I don't use bluetooth, but can't you use a bluetooth headset to terminate a call? –  Chance Sep 12 '11 at 23:06

Settings | Accessibility | Power button ends call

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

No such setting on my HTC Desire Z with Froyo 2.2 –  PP. Nov 19 '10 at 14:30
    
Too bad. It's one of my favorite hidden features of my Droid. –  Al E. Nov 19 '10 at 14:30
    
There is such a setting on the Galaxy Tab.. just not on the HTC.. –  PP. Nov 29 '10 at 12:21

Actually this setting on the Galaxy Tab is a curse! I tried calling a call centre, and whenever the screen turned off I pressed the power button to turn the screen back on, which aborted the call! I couldn't get through to the call centre to press different numbers on the keypad once the screen powered off! Terrible.. So I had to switch this option OFF on my Galaxy Tab. Who was the "bright spark" that thought a hang up button was unnecessary??? –  PP. Dec 30 '10 at 20:59
    
Excellent! This option is present in the LG Optimus One model. Finally! Thanks. –  Mugen Jun 1 '11 at 14:26

My first thought was the same as Al Everett's answer but if you, for some reason, don't have that setting, you can achieve it through Tasker.

  1. New Profile -> Event -> Hardware -> choose the button event you'd like -> Done
  2. + button on the left bottom corner to add a task
  3. Phone -> End Call -> Done

And you are ready to go ;)

you mean you can or can't? –  jlehenbauer Sep 13 '11 at 2:10
    
Yes, it is possible through tasker. I'll update my answer –  Diego Sep 13 '11 at 16:40
    
It seems to me the camera button would be an excellent candidate. –  Al E. Sep 13 '11 at 17:02
