Amazingly, the Galaxy S4 is thinner and lighter than its predecessor while doubling its processing capabilities and cramming HD-quantity pixels into its display. At 5.38 x 2.74 inches, the S4 is exactly the same length as the S3, and Samsung managed to trim four-hundredths of an inch from its width. Even more impressive, the Galaxy S4, at 0.31 inches, shaves three-hundredths of an inch from the Galaxy S3's thickness of 0.34 inches. At 4.6 ounces, GS4 weighs one-tenth of an ounce less than GS3's hefty 4.7 ounces.
Though we don't miss having less power than before, we were glad to see the return of something from a prior model. With its textured plastic shell, Samsung has instilled the Galaxy S4 with a more grippable design like that of the Galaxy S2's. And while it's still all made of plastic, the Galaxy S4's bezel is encircled with a handsome metallic ring. The Galaxy S4 retains the single hardware home button and soft buttons for menu and back functions.
