So you switched from a premium end of the spectrum to one of the cheap bargain basement models and are shocked it doesn't perform like your model that costs more than four times the price. the 640 is actually a great phone for the price. Windows Phone OS for many is far better than IOS, for others it is worse, personally I rate Windows Phone first then Android and way way down the list the slow cumbersome iOS, but it is all personal preference.
