when i pull my phone out of my pants pocket, it answers (and sometimes rejects, and sometimes simply locks-up) without me touching the screen. obviously, this is incredibly annoying to say the least. anyways... i was wondering if there's some way to set the phone up to answer by hitting one of the physical buttons on the phone (such as the volume up/down or power button) instead of using (and preferably disabling) the touch screen? ideally, i would like the option to stop the touchscreen from answering/declining a call until i press; volume-up to answer, or volume-down to decline. thoughts?
