There's a lot of people leaving their opinion without even having a Nokia 1020 here. I have one and I gotta say that I'm disappointed with this yellowish tint problem. I bought the phone because of its camera, and they say that the xenon flash would be better, but I compared my photos with a Samsung S3 and the S3 was much better. This pissed me off. Videos at night is just horrible. If I need to edit my photos everytime, then sorry, but it's just crap.
The S3 is not a better camera, its just not. Might want to look into some of the 1020's manual settings, like this and other threads about the issue suggest.
Cant say about night video, I never record video.
