Taking photos felt natural except at very high or low angles, which forced the wrist into an awkward position.
I found easy navigation of the touch screen one of the device's biggest pluses. Samsung has dispensed with buttons on the screen, so there's no home or back button. There is a button on the top right edge of the smartwatch face. Pressing it turns the display into a clock. One tap anywhere on the screen takes and saves a photo in the Gear and the smartphone that's paired with it. In clock mode, one swipe from bottom to top pulls up a numeric keypad.
