Design a modern Android app icon in Material style for a video wallpaper app. Use a rounded square background, dark navy to deep blue color palette, with a simplified phone or screen shape in the center. Inside the screen, include a clean play triangle symbol. Add subtle flowing wave shapes or layered motion ribbons behind the play symbol to represent animated wallpaper. Use Material Design 3 aesthetics: soft geometric shapes, minimal details, clean layering, balanced contrast, smooth highlights, premium but simple look. No text, no mockup, no border, no realistic objects, no clutter. High recognizability at small sizes, Google Play friendly.
