What has always puzzled me is that I thought Google made stock Android pretty dark-themed because they wanted to help manufacturers that used AMOLED screens, specifically Samsung, who makes like 95% of AMOLED's - and yet Samsung has chosen to use a very light-themed Touchwiz skin. It makes no sense. You'd think they would be the first to want to take advantage of a darker theme with their Super AMOLED flagship devices with large screens.
