|Samsung Galaxy S5, a minor evolution
Samsung unveiled its new flagship Galaxy S5 smartphone armed with a fingerprint scanner and a built-in heart rate sensor .
Taking center stage on the opening day of the world's biggest mobile fair in Barcelona, Spain, the South Korean company also revealed a connected bracelet.
Samsung made about 30 percent of all smartphones sold in the world last year, nearly twice the share of archrival Apple, which traditionally skips the annual World Mobile Congress.
Samsung showed off the Galaxy S5 with a light sensor on the back that gives a heart rate reading when the user touches it with his or her fingertip.
Though the case is plastic, as with earlier versions of the Galaxy series of smartphones, it is water and dust-proof, and has a leathery feel on the back.
The smartphone boasts a full high definition 5.1-inch screen, a 16-megapixel camera and, catching up with Apple, the home button doubles up as a fingerprint reader to unlock the device or to secure documents.
The phone has an extreme battery-saving mode that turns the display black-and-white and retains just six key applications.
To improve connections, it can combine a wifi signal and a mobile signal.
The Samsung Fit bracelet follows that trend, with a curved touch-screen display and a heart-rate sensor to help give users feedback during exercise routines.--AFP
