On Monday, Samsung announced the Galaxy S5, its premium smartphone followup to the Galaxy S4, and a challenger to Apple’s iPhone 5s for the top smartphone in the world. The Galaxy S5 features a crisp (and large) 5.1-inch display; new health tracking features, including a physical, finger-based heart rate monitor on the back of the phone and a built-in app to log meals; and a fingerprint sensor, which, like Apple’s latest iPhone, will let you unlock the phone with the touch of your finger.
