I agree, this is only since the 2.3 update. Is there anything that can be done about this? I miss having the old option to just hit the red "end call" button.

Now I have to just assume the call is ended and even then, I have to wake the phone up, swipe to unlock etc just to get back to my dialer. What if I want to make multiple calls in a row?

 

Interesting, this does not happen to me. My screen time out is set for 1 minute. I've taken the phone from my ear after a 20 minute call, and the screen lit right up, letting me end the call.

Or, if I'm on hold for a while, and then have to access the keypad to enter information, it's right there.

I have updated to GB.
