Siuuu HyperOS theme brings sleek transparent icons, anime‑style lock screen, depth‑effect wallpaper, and revamped UI. It works on any Xiaomi, Redmi, or Poco running HyperOS 3.0+ or MIUI‑based custom ROMs. Below is a hands‑on walkthrough, visual rundown, and post‑install checklist.
Visual style
Transparent icons → clean, minimal look. Icons use thin outlines, neon blue accents, and subtle drop shadows. Lock screen features a dark anime backdrop with a glowing “Siuuu” logo. Home screen widgets adopt a gradient bar, matching the accent color. Control Center icons swap to rounded shapes, giving an iOS‑like feel. Overall UI feels futuristic yet familiar; no aggressive color shifts, just a polished dark theme with occasional light highlights. The status bar adopts a semi‑transparent shade, letting the wallpaper peek through. Notification icons inherit the same thin‑line style, ensuring visual consistency across all panels.Who may like it
Fans of anime aesthetics → love the wallpaper and logo. Users who prefer minimal dark themes → appreciate the transparent icon set. People switching from iOS → enjoy the rounded UI elements. Power users on custom ROMs → like the extra depth‑effect wallpaper. Anyone bored with stock MIUI → gets a fresh look without extra apps. Graphic designers seeking a sleek backdrop for screenshots will find the contrast ideal. Streamers who want a clean on‑screen look for overlays also benefit.Compatibility notes
- Official HyperOS ROM (global stable) → works out of the box.
- Custom ROMs (Xiaomi.eu, MIUIRoom, HyperOS CN) → needs .mtz import via Theme Store.
- Device range → all Redmi, Xiaomi, Poco with at least 4 GB RAM; low‑end 3 GB devices may see slight lag on animation.
- Android version → 13+ recommended; Android 12 may miss some CC tweaks.
- MIUI version → 14+; older MIUI 13 may skip a few UI changes.
- Root → not required; theme works in stock and non‑root environments.
- Dual‑SIM phones → both SIM slots retain the same theme colors.
- Foldable models → only the main display receives the theme; the cover screen stays stock.

Post‑install tips
