With Samsung announcing the Galaxy S4, the battle is on for which company will rule the smartphone world. Here’s a look at the flagship phones from the major companies to help you make up your mind as to which one will be best for you.

The Galaxy S4 (sometimes called the SIV) will have enhanced software including a new “eye-scrolling” feature that lets users scroll through a page using their eyes. The phone runs on the Android operating system and will work as a TV remote control. The device’s main camera offers 13 megapixels and a second camera is 2 megapixels.

The major competitor to Samsung in the Android market is the HTC One, a smart-looking smartphone made out of a single block of anodized aluminum. The One has a 4.7-inch S-LCD3 panel with 1080p resolution. It also has an infrared device built-in that lets you use it as a TV remote control. The One is powered by a 1.7GHz quad-core Qualcomm Snapdragon 600 (APQ8064T), an Adreno 320 and 2GB DDR2 RAM.

Blackberry has been almost nonexistent for the last few years as the company repeatedly delayed that launch of its new phone and operating system. The first new phone, the Z10, which goes on sale in late March in the United States has received some positive reviews and has sparked hopes of a comeback for the company. The device lacks the hard keyboard that Blackberry has traditionally used, opting instead for a virtual keyboard like the other phones on this list. A Blackberry with a physical keyboard will be released later this year.

The iPhone 5 was Apple’s first major redesign of its popular phone running on its proprietary iOS operating system. The 5 has a larger display than its predecessors and it’s thinner and lighter. The phone also features the Siri virtual assistant which operates off of voice commands. The iPhone 5 also has Apple’s Retina display which Apple said offers “326 pixels per inch—a pixel density so high your eye can’t distinguish individual pixels.” And, of course, the iPhone has the advantage of being tied into Apple’s app store which has an overwhelming array of apps for iPhone users.

Another elegant-looking phone, the Nokia Lumia 920 series is the flagship phone for Microsoft’s Windows Phone 8 operating system. Based around live tiles, which bring info like stock prices or sports score right to your opening screen, Windows Phone 8 represents Microsoft’s attempt to offer customers a similar experience whether they are on a computer, a tablet, or a phone. The 920 offers a one-piece polycarbonate body and a 4.5 inch display.
