The Droid I just got the other day started out nice and solid, and I guess you get a little break in from utilizing the slider enough times. The play between the screen and the slider was getting quite annoying as it felt like I was typing on a Storm.
Probably not the most recommended way to do it, I made sure to be REALLY careful about it. Being that the unit is made of thin metal, I took it position by position and put some tension inwards to get the metal to ever so slightly bend in until the unit for the most part stopped having the 2 parts click together everytime I am tapping on the screen, particularly with the virtual keyboard.
So if it is bugging you as much as it was bugging me being everything was perfect EXCEPT for that play between the 2 parts, be it risky, it could be worth a shot, heh heh I take no responsibility for results unless of course it works like a charm
