Cartoon-style themes usually go one of two ways: either they look genuinely fun, or they end up looking childish on a phone you use for work all day. The OX F4 HyperOS Theme lands firmly on the fun side. It’s a premium-grade theme with a playful cartoon icon set, matching wallpapers, and enough customization options that it doesn’t feel like a one-size-fits-all download. And at just over 56 MB, it’s still light enough to install without a second thought.
Why OX F4 HyperOS Theme Stands Out
A lot of “premium” themes only change your icons and call it a day. OX F4 HyperOS Theme goes further; the lock screen, status bar, and Always-on Display all get reworked to match the same playful, colorful aesthetic, so nothing on your screen feels mismatched. If you’re someone who likes switching up your phone’s look every few weeks, this theme also leans customizable, meaning you’re not locked into one rigid layout once you apply it.

Get the Theme
Installing on Stock HyperOS / MIUI (Official ROM Users)
If your phone is running the official Global Stable build of HyperOS or MIUI, follow these steps:
- Open this page using the Firefox browser on your phone.
- Tap the official Theme Store link in the download section above.
- You’ll land on a Xiaomi theme page written in Chinese, that’s normal. Tap the three dots in the top-right corner and choose “Open in app.”
- This hands off to your Themes Store app, where the download starts automatically.
- Once it finishes downloading, tap Apply.
Heads up: If the Theme Store link doesn’t open properly, try switching to Chrome or your phone’s default Xiaomi browser. Some third-party browsers block this redirect.
Installing via MTZ File (Custom ROM Users)
Running a custom build like Xiaomi.eu, MIUIRoom, or another MIUI/HyperOS-based ROM? Sideload the file manually instead:
- Download the
.mtzfile from the link above. - Open the Theme Store app and go to the Themes tab.
- Scroll to the bottom and tap Import.
- Select the
.mtzfile you just downloaded. - Tap Apply.
Tip: Restart your phone after applying the theme. If any icon, wallpaper, or lock screen element looks slightly off right after applying, a quick restart almost always fixes it. This theme has been tested and applies cleanly with no reported issues.
Final Thoughts
The OX F4 HyperOS Theme is an easy recommendation if you want your phone to feel a bit more playful without going overboard. The cartoon icons and matching wallpapers give it a cohesive, put-together look, and the customization options mean you can still tweak things to fit your own taste. It’s free, it’s quick to install, and it’s a solid change of pace from the usual stock HyperOS look.
