Galaxy S5 lists a heart-rate sensor among its array of self-awareness probes, which also includes humidity, barometric pressure, proximity, gesture and a magnetic hall sensor for accessories. In common with Apple are accelerometer, gyroscope, compass and ambient light circuits. But for processing sensor data, Apple stands alone with its dedicated M7 motion processor and CoreMotion API. And with the addition of a fingerprint scanner in its home button, Samsung catches up to Apple for unlocking the screen. But Samsung leapfrogs Apple with the added ability to conduct secure commerce and privatize a section of device storage.
