The S4 has an excellent 5-inch, high-definition (1080p) touch-screen display, as well as oodles of gesture- and sensor-based tools for accessing and sharing content you create and capture on your phone. The display is sensitive enough to use with gloves on—handy during cold weather.
A true multi-tasker, the S4 lets you run two apps simultaneously in a split-screen view. For instance, you can watch a video while checking e-mail, or you can use Google Maps and Messaging simultaneously. We did find that battery life and voice quality varied slightly between cell carriers, as with the LG Optimus G.
In January, Consumer Reports ranked the Samsung Galaxy S III, LG Optimus G, Motorola Droid Razr HD, and Motorola Droid Razr Maxx HD as better smartphones than the iPhone 5.
