touch the side (Metal Part) while using it.
Or at least that's what I've seen on my device. I noticed that the touch screen is a little jumpy after seeing a thread on here about a Screen Test where the Droid did poorly (The test seemed bogus to me but that isn't the issue I wanted to discuss).
Anyways, I was just lounging about on my futon and was fiddling with the pull up App Tab and noticed that it jumped a lot if I only used one finger to drag it up and held it in the middle. But when I put a finger on the metal surrounding it steadied it to a perfect stand still. Since I have no friends with Droids (Which obviously means they aren't my friends now) I was wondering if anyone else can vouch for this phenomenon.
