Smartphone displaying abstract gradient wallpaper on textured background

Rendered mobile device positioned centrally on dark cubic textured surface. Screen displays abstract gradient composition transitioning from cool blue tones in upper section through magenta and red hues to warm yellow-orange masses in lower-middle region. Notch visible at top of display. Gradient employs soft-edged polygonal or liquid-form shapes rather than linear transitions. Dark backdrop demonstrates high-resolution cube mapping with varied surface values creating dimensional effect through shadow differentiation and reflective properties.
