I can't tell you a general reason why "the masses" buy the iPhone; I only can tell you why I bought the 5s and 6s. And I don't care what a cheap phone can do; my f150 can tow a heavy load, something my expensive Ferrari can't.Stutter is actually a major reason why many switched to iPhone in the first place.The 2 things you mentioned can be done even on a 100 dollar Android phone.Thing is its not smooth doing it
