Gradient display phone against blurred cityscape backdrop.

Against a soft-focused urban environment, this smartphone showcases a vibrant gradient wallpaper rendered in magenta, cyan, and violet hues with ethereal cloud formations. The device sits upon a reflective surface, its edge-to-edge screen displaying dynamic color transitions that blend pink clouds through blue atmospheric elements. Night city bokeh lights frame the composition peripherally, emphasizing the phone's luminous display through sharp optical contrast between the sharp device and diffused metropolitan setting.
