Modern smartphone with vibrant gradient wallpaper

Contemporary smartphone rendered with precise 3D modeling displays fluid gradient wallpaper. Display features systematically layered color transitions: warm yellow-orange upper section transitioning through coral-pink midtones into magenta-violet lower band. Organic wave-form boundaries separate each color layer with soft mathematical curves. Device positioned front-facing against neutral dark gradient background. Black bezels frame display edge precisely. Notch cutout visible at screen apex. Technical execution demonstrates advanced material simulation and lighting rendering.
