The pics I've been taking recently on my Desire have generally been of horrible quality. I've not really played with the settings, apart from changing ISO to 800 rather than Auto, both of which still produce pics with lines across. It also doesn't matter whether the pics are taken inside or outside, light or using flash. I've also cleaned the lens and tried without the back cover on. Here's a small part of a recent pic of my son.... Can anyone advise if this is normal, or is a return to the shop necessary?
