Compatibility	HyperOS, HyperOS 2.0, MIUI	Cartoon‑Inspired Icon Pack That Pops

OX F4 leans heavily into a playful cartoon aesthetic. Icons are rounded, slightly exaggerated, and use a vivid palette of blues, pinks, and yellows. The set stays consistent across system apps, third‑party launchers, and the built‑in theme store. Even the tiny notification icons receive the same treatment, so nothing feels out of place. The design avoids overly complex details, ensuring clarity on high‑density screens while still feeling fresh.

Fresh Wallpapers & Dynamic Lock Screen

Beyond icons, the theme ships with a curated gallery of high‑resolution wallpapers. Each image echoes the cartoon vibe—cityscapes with neon outlines, stylized nature scenes, and abstract patterns. The lock screen adopts a subtle parallax effect, giving depth without draining battery. The Always‑On Display (AOD) mirrors the wallpaper’s color scheme, displaying time and notifications in matching typography. Users report that the AOD remains legible in both bright daylight and dim rooms.

Seamless Integration with HyperOS & MIUI

Compatibility is a strong point. OX F4 declares support for HyperOS, HyperOS 2.0, and MIUI, covering the majority of Xiaomi, Redmi, and POCO devices on stock ROMs. The theme respects system‑wide dark mode, automatically swapping icon tones when the UI switches. Status bar elements—battery, signal, and clock—are recolored to match the wallpaper’s dominant hue, creating a cohesive look. On custom ROMs that retain the Theme Store framework, the theme imports without conflict.

Installation Walkthrough & What to Expect

1. Open the Theme Store app (or a compatible third‑party theme manager). 2. Tap Import and locate the downloaded OX F4.mtz file. 3. Confirm the import; the app will validate size and format. 4. Apply the theme from the My Themes section. 5. Reboot or lock‑unlock the device to let the AOD and lock screen refresh.

During installation the system may prompt for permission to replace existing icons. Accepting will overwrite the stock set but keep a backup in the theme manager, allowing a quick revert. Expect a brief pause (5‑10 seconds) as the theme unpacks the 56 MB package. After applying, check the notification shade for any missing icons; a quick Clear Cache in Settings can resolve residual glitches.

Pros and Cons

- Pros - Cohesive cartoon style across UI elements - High‑resolution wallpapers with parallax lock screen - Full Dark‑Mode support, auto‑adjusting colors - Compatible with both HyperOS and MIUI stock ROMs - Easy import via MTZ file, no extra tools required

Cons
Limited to devices running HyperOS 2.0 or MIUI 14 and above
