Compatibility	HyperOS, MIUI on Redmi phones	Immersive Depth‑of‑Field Visual Language

The theme treats every screen as a shallow pool of light. Lock screen gradients melt into the notification shade, while app icons appear to float above a subtle haze. The wallpaper set uses a soft bokeh effect that shifts with ambient light, giving the illusion of depth without overwhelming the eye. System UI colors stay muted—charcoal, slate, and muted teal—so the depth effect remains the focal point. Even the navigation bar adopts a translucent glass look, reinforcing the overall fluid aesthetic.

Ideal Users and Aesthetic Fit

Fans of cinematic UI will gravitate toward this theme. If you enjoy subtle motion, layered shadows, and a polished finish, it feels like a natural extension of a high‑end smartphone experience. Graphic designers, mobile photographers, and anyone who spends hours scrolling will appreciate the reduced visual noise and the way icons pop against the blurred background. Minimalist lovers will also find a home here; the theme avoids loud colors, relying instead on tonal harmony and depth cues.

Installation Walkthrough for Stock and Custom ROMs

Stock HyperOS / MIUI 1. Open the Themes app. 2. Tap the “Import” button and locate the MTZ file (≈39 MB). 3. Confirm import; the theme appears in your library. 4. Apply and restart if the UI shows overlapping elements.

Custom ROM (e.g., Xiaomi.eu, MIUIRoom)

Download the backup ZIP (≈57 MB) to internal storage.
Launch the Themes app, choose “Import”.
Navigate to the ZIP file and confirm.
After import, select the theme and apply.
Reboot to ensure lock‑screen elements render correctly.

Both methods require enough free space—at least 100 MB—to unpack assets. The theme works without root; however, root users can place the ZIP in /system/theme for faster loading, though this is optional.

Performance Impact and Battery Considerations

The depth‑of‑field effect is largely shader‑based, relying on the GPU rather than the CPU. On modern Snapdragon chips, the extra load is negligible; frame rates stay smooth across the home screen and app drawer. Battery draw sees a marginal increase (≈2‑3 % per hour) during heavy UI interaction, but idle consumption remains unchanged. Users with older hardware may notice a slight lag when opening the recent‑apps view, but the theme includes a “Performance Mode” toggle that disables the translucent navigation bar, restoring responsiveness.

Pros and Cons

- Pros - Cohesive depth‑of‑field visual language - Low‑impact GPU shaders, smooth performance - Compatible with both stock and custom ROMs - Clean icon set, easy on the eyes - Simple one‑step import for MTZ files - Cons - No dark‑mode variant; relies on muted tones - Slight performance dip on legacy devices - No built‑in wallpaper rotation, requires manual change - Backup ZIP size larger than MTZ, consumes more storage
