"Again, Samsung pioneered this by adding OIS to its new Galaxy Note 4 and Galaxy Note Edge. We haven't had a chance to test out the OIS in these cameras"
good job proclaiming something the best camera without even checking out the competition.
"The Samsung, and some other phones, also shoot video at Ultra HD (aka 4K) resolution. But really, there aren't many places to watch that video, and it seriously hogs storage space on a phone. "
Storage is not an issue if the phone has expendable storage; coincidentally, Samsung phones offer that option. Again, the OP felt the need to downplay a feature not present in the iPhone, but offered by the competition.
Such "reviews" are the main reason I am getting serious tech news elsewhere. I am not even making Samsung's case here, just pointing out bad journalism.
The larger iPhone 6 Plus also incorporates optical image stabilization — a technology that's almost universal in point-and-shoot cameras, but very rare in phones. Again, Samsung pioneered this by adding OIS to its new Galaxy Note 4 and Galaxy Note Edge.
Nokia makes the best smartphone cameras hands down. The iPhone 6's 8MP shooter may be able to let in more light, but it cant handle as high of an ISO as the 1020 or 1520 can. From the sample shots I looked it, they were horrible. Way too grainy. Not even close to Nokia's quality.
