But how does it compare to the top-selling phone on the planet, the iPhone?
I took a look at the most important categories for smartphone buyers and broke it down for you.
A quick note on scoring: In earlier stories like this, Business Insider gave each category equal weight. That doesn't make sense as some features like app selection are way more important than design. From now on, we'll be scoring each category based on importance.
Design (1 Point)
The iPhone is gorgeous. The Samsung Galaxy S III is gorgeous.
So which one is better-looking?
We're going with this Galaxy S III on this one. The iPhone 4/4S design has been around for two years and it's starting to feel stale. The Galaxy S III is thinner, lighter, and sports that gorgeous giant screen. We're expecting a new look for the iPhone this fall, but the Galaxy S III wins for now.
Galaxy S III: 1
Build quality (1 Point)
Despite its good looks, the Galaxy S III still feels cheap. That's because Samsung made the entire body out of flimsy plastic.
On the other hand, the iPhone is all metal and glass. It feels like a high-end product. It may be heavier, but I'll take that over plastic any day.
Galaxy S III: 1
Screen (2 Points)
A 4.8-inch screen would've sounded bonkers a year ago. But what Samsung pulled off with the Galaxy S III is pretty darn impressive. The phone's designers were to keep the display's bezel super thin, so the device isn't absurdly large. (Unlike the practical-joke-sized Galaxy Note.)
Aside from the size, the quality is amazing. It's a delight to watch videos and play games on a big, bright screen. The iPhone's screen may look good, but in this case, bigger is better.
