OX F3 HyperOS Theme with Cartoon One UI Style with Dynamic Lock Screen for Xiaomi, POCO, Redmi

Samsung’s One UI aesthetic keeps popping up as inspiration for HyperOS themes, but OX F3 HyperOS Theme Xiaomi takes it in a lighter, more playful direction than most, blending that clean One UI structure with cartoon-style visual touches rather than a strictly serious, corporate look.

Designed by oxfury 0.2 alongside masuod, it’s built around a dynamic lock screen and comes in at 45.58 MB for Xiaomi, Redmi and POCO devices running HyperOS or HyperOS 2.0. Worth flagging early: a few users have reported the official store link failing to open on certain devices, more on that below.

OX F3 HyperOS Theme Key Features

1. Cartoon-Inspired Visual Style: Rather than going for a strictly minimal or corporate One UI look, OX F3 HyperOS Theme works in playful, cartoon-style elements throughout its icons and visual accents. This softer approach gives it a friendlier feel than the typical serious take on Samsung-inspired themes.
2. One UI Structural Influence: The underlying layout borrows Samsung’s rounded shapes and generous spacing rather than sticking to HyperOS’s native design language. That structural DNA is what actually makes it recognizable as a One UI-style theme, separate from the cartoon visual touches layered on top.
3. Dynamic Lock Screen: The lock screen incorporates movement and shifting visual elements rather than a plain, static layout. It’s one of the theme’s headline features and adds some life to the unlock experience beyond just a redesigned clock face.
4. Designer-Verified, Original Work: Unlike a lot of free themes floating around, OX F3 comes with a clear statement from oxfury 0.2 and masuod that it’s their own original design, built with some resources from other creators but not a repackaged copy of someone else’s work. That’s worth knowing given how much lower-effort content gets passed around in this space.
5. Active Designer Support Channels: Both designers maintain dedicated Telegram channels for feedback and troubleshooting rather than disappearing after release. If something doesn’t render correctly on a specific device, there’s an actual place to flag it.
6. Compact for the Amount of Detail Included: At 45.58 MB, it’s a moderate download considering the cartoon icon redesign and dynamic lock screen animation packed in. Not the lightest theme around, but reasonable for what it includes.
7. Limited to Newer HyperOS Versions: OX F3 HyperOS Theme supports HyperOS and HyperOS 2.0 specifically, and at least one user has asked the designers for a version compatible with older MIUI builds and devices, a request that, as far as the current release goes, hasn’t been implemented. Anyone on an older MIUI version should keep that in mind before downloading.

OX F3 HyperOS Theme Preview

The screenshots below show the cartoon-style icon redesign, the One UI-inspired layout and how the dynamic lock screen looks once the theme is applied. Since the blend of playful cartoon elements with a more structured One UI base is a bit unusual, it’s worth looking at the preview closely to see how the two styles actually come together.

OX F3 HyperOS Theme Compatibility

OX F3 supports HyperOS and HyperOS 2.0 across Xiaomi, Redmi and POCO devices, but it doesn’t currently extend to older MIUI versions or HyperOS 3.0, a limitation at least one user has specifically asked the designers to address. A genuine caveat worth knowing before downloading: some users have reported the official Theme Store link failing to open properly on their devices, so it’s worth having the direct MTZ file download ready as a backup if the store redirect doesn’t work the first time.

Custom ROM users on setups like Xiaomi EU ROM or MIUIRoom can still install manually through the MTZ file, and given how much the dynamic lock screen relies on animation, older or lower-powered devices may render it with slightly less smoothness.

Get OX F3 HyperOS Theme

Download OX F3 HyperOS Theme MTZ only through the official Theme Store link or the direct MTZ file, not random third-party file hosts or unofficial APK uploads. Files sourced outside verified channels are difficult to confirm as unaltered and may not reflect what oxfury 0.2 and masuod actually released. Sticking to the official links keeps the installed version consistent with the intended design and ensures any future updates remain accessible.

Important notice from the designers: OX F3 is fully designed and developed by oxfury 0.2 and masuod, with some resources sourced from other creators. The designers have specifically asked that no part of this theme be copied, re-uploaded, or modified without permission, noting that unauthorized use will be reported to Xiaomi as a copyright violation. Anyone with feedback or questions can reach the designers directly through their listed Telegram channels. This is a genuine copyright request worth respecting given the original work that went into the theme’s design.

How to Apply OX F3 HyperOS Theme

Follow the steps below to apply the theme:

1. Open the Theme Store link given above on your Xiaomi, Redmi or POCO device.
2. This will redirect you to the Theme Store.
3. Download and install the theme.
4. Tap on Apply.
5. Customize specific elements such as icons, lock screen or status bar if needed.
6. Reboot your device for the full effect, though this step is optional.

Note: If the Official Theme Store link doesn’t open, switching to Chrome or your device’s default Xiaomi browser tends to help, since a few users have reported the link failing entirely on other browsers. If you’re on MIUI 14 specifically, there’s a separate video walkthrough worth following instead of the standard steps. Restarting the device after installation is worth doing if anything looks overlapped or fails to display correctly, and reaching out through the designers’ Telegram channels is the most direct way to get help if a problem persists.

Installing OX F3 HyperOS Theme on Custom ROM Devices

Devices running MIUI 11 through 14 or HyperOS based Custom ROMs such as Xiaomi EU ROM or MIUIRoom aren’t able to use the direct Theme Store link, so the MTZ file needs to be brought in manually instead. Here’s how that works:

1. Grab the MTZ file for OX F3 from the download section.
2. Open the Theme Store app.
3. Go into the Themes tab.
4. Scroll down to find the Import option, then tap it.
5. Use the file manager to locate the downloaded .mtz file.
6. Wait for the import process to finish.
7. Tap the theme once it appears in the list to apply it.

Why Choose OX F3 HyperOS Theme?

• Distinctive cartoon-meets-One UI look — a friendlier take on the usual serious Samsung-style theme.
• Genuinely dynamic lock screen — real movement instead of a static, fixed layout.
• Verified original design — a clear designer statement backs up the theme’s originality.
• Active support channels — direct Telegram access to the designers for feedback or issues.
• Backup MTZ download available — useful given the occasional Theme Store link issues reported.
• Free official download — no cost involved once accessed through the correct channel.

Conclusion

OX F3 HyperOS Theme finds an appealing middle ground between structured One UI design and playful cartoon detailing, backed by a dynamic lock screen that adds real personality to the unlock experience. The store link issue some users have run into is worth planning around, keeping the direct MTZ file handy as a backup solves it easily enough, and the lack of older MIUI support is a real limitation for anyone on legacy devices. For Xiaomi, Redmi and POCO users on HyperOS or HyperOS 2.0 who want something a little more fun than the typical One UI clone, OX F3 is worth trying.
