Holy effing crap, that worked! I smacked the hell out of it on my hand about 30 times, all sides, all angles...nothing. Waited a while, figured I'd try again - this time I was droppedit onto my desk a few times. BAM! Unstuck sensor. Now that I think back, I think I dropped my phone yesterday, so that must've been what got it stuck to begin with. Anyways, many MANY thanks!!
