Most of the functions work fine on my Droid. There are few that do not. About the only functions I've used are the Windows Transitions and Animations settings. I moved their speed up to the max and I love the way it makes things "snap" on the Droid.
I just turn these off in the settings... Give that a try and see how "snapier" your phone is
HA! You are correct! (this may be the closest I've ever come to being wrong!!). It is snappier. A few programs do go to a black screen first, but I'll leave it this way for a while and then switch them back on at the fast setting. Thanks for the tip and good catch.
