I'm using the Camera360 app. There is a filter called "Effect enhancement". If i you this one, the pictures look better - the ones taken in short range. Ok, they do look a bit "artifical", but for me its ok. There is a "free" version of that app for trying out...
The Defy is not the first Android i bought, but it will be the first Android, which will not be sold again. I really like this phone...
Maybe there will be some kind of camera-optimization. Until then, i will take my digi-cam for "more important" pictures to make.
