What's this about? Is this why we don't get the Exynos in the US?
Pretty much. Qualcomm owns a bunch of patents so companies like Apple and Samsung have to pay royalties to license CDMA radios to use on Verizon and sprint.
It's cheaper for them to use snapdragon I think.
Performance isn't the issue for me though, but mostly memory management. Any game I have will basically reload at any app switch lol. 4gb ram my asshole. Seems to be a common trait with samsung phones regardless of processor.
