If I take a picture using the trackball I tend to get blurry pictures. However if I long-press on the screen on top of the area that I most want to be in focus (subject's face, for instance) then the camera auto-focuses AND snaps the shutter (or the digital equivalent) - no need to press the trackball. Doing it this way I get nice crisp pictures.
Edit: Took a picture of my store. This is set at 3mp and the store is not overly brightly lit. BTW, I took ONE picture, not a series and then chose the best one. I have no problem with a phone that takes pictures of this caliber.
I trust the mods won't bust me for shameless advertising. This is in keeping with the topic of the thread, and hey - I'm at work, it's the only thing around to take a picture of (you have to admit the colors are pretty...).
