I can't be the only one who has this problem: my touchscreen reacts to the cotton of my jeans. I carry my DHD upside down in my pocket, and on an incoming call, when I drag it out of my pocket, it interacts with the jeans tissue and slides the bar up, thus declining the call.
I tried such apps as "Easy answer button," "Advanced telephone," "Full screen caller ID," but they simply overlap what's already on the screen, and while they do work (i.e., I press instead of swiping), either the result is very ugly, or the caller ID is partially invisible — not to mention I would like to swipe left/right (as in vanilla Android), rather than just press, as this is also not jeans-proof.
