The Samsung Galaxy S4 is shaping up to be a pretty amazing device. Normally we’re wary of making such predictions ahead of time, and usually shy away from them. But short of a colossal screwup, it’s tough to imagine a way Samsung could blow the Galaxy S4’s release next month, even despite the company’s ill-conceived, over-the-top production surrounding its unveiling at Radio City Music Hall last week.

The thing is, here at PCMag, many of us are also fans of the Nokia Lumia 920. Windows Phone owners consistently rated their favorite mobile OS the best in our 2013 Readers’ Choice Awards, so clearly Windows Phone also has its share of dedicated fans. Could the Galaxy S4 be good enough to sway those people to Android? Let’s break it down and find out.

Make no mistake: The Lumia 920 is a beautifully crafted phone. While both devices are made of plastic, with the exception of the glass screen, the Lumia 920 looks and feels more expensive, thanks to its thick polycarbonate construction and rolled edges. However, you pay for that in weight; the Lumia 920 weighs a hefty 6.5 ounces, which is nearly two full ounces heavier than the sleek, thin Galaxy S4.

The Galaxy S4 also gives you a better screen, as nice as the one on the Lumia 920. The Galaxy S4’s 5-inch, 1,920-by-1,080-pixel (1080p) Super AMOLED panel is a significant jump over the Lumia 920’s 4.5-inch, 1,280-by-720-pixel (720p) ClearBlack screen. In the real world, that may matter a little less than it appears. Despite the half-inch difference in size and lower resolution on the Lumia 920, both screens look gorgeous, though it’s tough to deny the advantages of having all that extra real estate with which to play.

Processor-wise, it’s no contest. The Galaxy S4’s quad-core 1.9-GHz Qualcomm Snapdragon 600 should benchmark considerably faster than the Lumia 920’s dual-core 1.5-GHz Qualcomm Snapdragon S4.

There’s no need to rehash the app wars here, but while Windows Phone 8 is a pleasure to use throughout, its app catalog, while considerable, still lacks ports of many popular iOS and Android apps. That doesn’t bother many Windows Phone fans, because there are alternatives in almost all cases; they’re just different, that’s all. On the other hand, the Galaxy S4 runs Android 4.2.2 Jelly Bean, the latest version of Android with Google Now, Photo Spheres, and Miracast support, plus all of Samsung’s considerable enhancements to the OS. 

Nokia makes a big deal about the Lumia 920’s camera, and with good reason. While it’s down on megapixels versus the Galaxy S4 (8.7 to 13), the Lumia 920 delivers top-notch photos and beautiful 1080p video recording in many conditions. Still, it’s not perfect, as we found in our review. Samsung has a real chance here to beat the Lumia 920 with its higher-resolution rear sensor and 1080p front-facing camera.

So on paper, at least, the Galaxy S4 has a small but significant advance over the Lumia 920 in most respects, notably including the screen, the processor, and the two cameras. Let’s turn it over to you, now. Do you think the Galaxy S4 beats the Lumia 920, or does the Lumia 920 still win out thanks to its Windows Phone OS and well-tuned camera?
