Two days ago my Curve's trackball started messing up. WHenever I was browsing through my texts, all of a sudden it would stop letting me scroll down and I couldn't move down on my messages. Then several seconds later it would work again. Is there something wrong with my trackball? This is the first time it's ever done this. My trackball is fairly clean though. I try not to use my phone when my hands are dirty.
Also, is there a way to control volume (Loud, quiet, silent, and vibrate) by just using the volume rockers? Or do you always have to select the option in the menu?
