On the first day with my phone, I set all 3 to 0 and couldn't figure out why I couldn't long press on home screen to get popup with choices. Read somewhere here on the forums that animator duration needed to be set to .5 to get that option back. I changed that one to .5 and had the long press popup menu again.
Last night I set animator duration to 0 (all three on 0) and still had the long press menu. Not sure what changed but something did.
