Disregarding the survey, valid or otherwise, in the tests I've done my new SIII doesn't fare particularly well against the two-year old Sony Xperia X10 that it replaced. Whilst I'll be the first to admit that I've not tried all the modes, white-balance, etc - the tests that I have done (mainly indoors because the weather's been atrocious) seem to show that florescent lighting especially gives you over-saturated, over-compressed results more akin to a bargain bucket digicam rather than a very expensive "latest thing" smartphone. I'm hoping that this is solely a software issue, in which case perhaps there'll be a fix forthcoming.
Like I said, overall I'm impressed with the SIII - it does a very high percentage of things asked of it very well, which makes the poor pictures a bit annoying. That said, I've also seen discussion that the One X's camera is quite good.
With hindsight, it's just struck me as a bit weird that I'm getting even slightly bothered by this - after all, even the best smartphone is a compromise and for anything decent you'd be better off with a "proper" digicam.
