The phone opens and closes on a seven-second loop, pausing for one second at each end. Pause the loop or touch the slider to take control. Slide left to close, right to open. Touch the phone to snap to the nearest endpoint, then drag to rotate. Touch the slider to return to the straight-on view. Slider arrow keys adjust precisely; Home closes and End opens. With the phone focused, arrow keys rotate and R resets the view.
