At it's Unpacked event in Barcelona, Samsung has released the Galaxy S5 -- and, to the surprise of everyone, three new smartwatches: the Gear 2, Gear 2 Neo, and the Gear Fit. We'll talk about the smartwatches in a separate story; we'll focus on the Galaxy S5 here. The Galaxy S5 is, for all intents and purposes, the Galaxy S4 but with a few cool new features: A fingerprint scanner, a heartbeat sensor, and some tech that constantly calibrates the OLED screen to compensate for ambient lighting, to ensure that those gaudy super-saturated colors are always present no matter the conditions. The Galaxy S5 is indeed splash-proof (similar to the S4 Active), but not ruggedized.
