honestly don't understand the different between all these phones. as long as it browses, has news apps, gmail, facebook, and looks decent I couldnt care less about anything else. The interface is basically the same between android and iphone, nokia is different but confusing as fuck cuz Im so used to android.
Processing power, battery efficiency and capacity, display clarity, device size/weight/design, durability, software lifespan, ease of use, etc. etc.
