The Galaxy S4 zoom works much like other Android phones from Samsung, except that it has a real zoom lens, offering up to 10 times magnification. Other camera phones have digital zoom features, or magnification using software, but all that does is blow up shots without boosting clarity. With the optical zoom found in the Galaxy S4 zoom and standalone cameras, you retain the sharpness as you zoom in. The Zoom's 16MP is better than most phones. The downside: It's not available in the US yet.
