That's because Apple maintains a higher standard of quality than Samsung. I'd like to see a chart that shows actual sales/activation of iPhone vs. Samsung Galaxy series only in the last two years. I have yet to see one that doesn't encompass all of the cheap, crappy Samsung freebies. I'd bet that once the iPhone 6 Plus and 6S Plus become free-on-contract, these numbers will change. Also, Apple has been making huge leaps in improving iOS. There's a reason why so many people this year switched from Android to iOS.
