After months of leaks and speculation, Samsung finally took the wraps off its newest flagship phone, the Galaxy S5. Samsung’s phones already track the steps you take and the calories you burn, but the S5’s can track your heart rate through a fingertip sensor on the back of the phone. Samsung’s newest phone also comes with a fingerprint reader, which you can register up to three unique fingerprints on, that lets you authorize PayPal to make online payments for anything. This feature also lets you unlock Private Mode, making it easy to hide your more personal things from people like your co-workers or your children. The Galaxy S5 got a major boost in the camera department, too, with a rear-facing 16 megapixel camera that focuses in less than a third of a second, as well as the ability to capture video in 4K resolution. If all this adds up to a phone you’ve just got to have, Samsung’s Galaxy S5 will be on sale in over 150 countries on April 11.
