I can't answer phone calls in some situations
I'm not sure of the Motorola methodology for answering or ignoring a call, but on my Samsung, merely touching the green or red button is insufficient; it requires a swipe to convey the intention. I believe this was re-engineered to prevent accidental accepts or hangups through a mere button press. The green button has green arrows and a swipe in the arrow direction from the button will accept the call. The same with the ignore swipe along the red arrows from the red button to indicate the call should go to voicemail.UPDATE: Searching the Droid forums, I see that Motorola uses the same functionality for call answering, but many users would like to see the functionality changed to just a button press. Perhaps you are an advocate of the same technique. See this forum for suggestions others have made to change the functionality somehow through app replacement:http://www.droidforums.net/forum/android-app-developers/37743-button-answer-call-instead-swipe.html
