Screen: The S4’s five-inch touchscreen is slightly larger than the Galaxy S3’s 4.8 inches. But it is substantially larger than the iPhone 5’s four inches.
The screen size alone will be a key benefit over the iPhone 5 for many business users. When you’re working with documents, databases, or taking notes, a larger screen is often easier to use — especially for touchscreen typing.
The resolution of the S4 display is comparable that of the iPhone 5’s Retina display. The S4 features a high-definition Super AMOLED screen, with a resolution 441 pixels per inch (ppi). Apple’s iPhone 5 Retina display has a resolution of 326 ppi.
Memory: If you need access to large files or lots of video, the S4 should give you more memory than the iPhone 5. Like the iPhone 5, the S4 comes with built-in memory options of 16, 32 and 64 GB. But the S4 also has a microSD slot that accommodates memory cards up to 64 GB. And you can carry as many of those around as you like.
Size: The S4 is thicker and heavier than the iPhone 5. The S4 weighs 130 grams and is 7.9mm thick while the iPhone 5 weighs only 112 grams and is 7.6mm thick. (But by contrast, Samsung’s Galaxy Note 2 phablet weighs a whopping 182.5g and is 9.4mm thick.)
Operating system: The S4 comes with the latest version of the Android mobile operating system, 4.2.2 “Jellybean.” I’ve been using Jellybean for most of the last year, on my Samsung Galaxy Nexus. I’ve used both Apple’s iOS mobile operating system and prior versions of Android and I believe, with Jellybean, Android is finally as easy to learn and use as iOS.
But there’s a crucial difference between the version of Android I use on my Galaxy Nexus and the version that comes on any of Samsung’s Galaxy S series phones (including the S4). All “Nexus” model devices run the unmodified (“stock”) version of Android — which means that as soon as Google releases a new version of Android, stock Android devices get that update immediately and directly from Google. This is comparable to the iPhone — all iOS devices get immediate OS updates direct from Apple. And this is important if you can’t wait to take advantage of new OS capabilities, support for newer apps and bug fixes.
