Designer	-
Size	63.2 MB
Format	MTZ
Compatibility	MIUI 12+ / HyperOS 1+ (MTZ)	Playful Koala Aesthetic & Animated Lockscreen

pastel greens + soft browns → calming vibe
koala mascot roams home screen icons → cute factor ↑
right‑swipe lockscreen → koala slides open → instant wow
petal fall effect → enabled by default, toggle in Settings → low‑end devices may see FPS dip
tap koala → water‑sprinkle animation → adds interactivity
calendar widget integrated → quick date jump, step count shortcut → useful for fitness buffs

Target Audience & Use‑Case Scenarios

- users who love nature‑themed UI → kids, casual users, animal fans - minimalists? → icon set stays simple, background stays subtle → not cluttered - power users seeking animation? → lockscreen gestures provide visual flair without heavy CPU load (mid‑range OK) - night‑mode lovers → theme respects system dark mode → colors shift to muted tones → eye strain ↓ - regional Chinese users → native fonts & language strings → no extra font install needed

Device Compatibility & Known Issues

- req: MIUI 12+ or HyperOS 1+; both must support MTZ package → flagship & recent mid‑range devices pass - known bug: on some A‑series ROMs, petal animation stalls after screen timeout → workaround: disable "Petal fall" in Theme settings - RAM < 2 GB → animation lag ↑ → recommend turning off lockscreen swipe - custom ROMs lacking Theme Manager → cannot apply MTZ → need official Xiaomi firmware - OTA update may reset theme → re‑apply after major system update

Installation Walkthrough & Post‑Install Tweaks

1. Download → choose any server link, tap → file saved as Koala_Backyard.mtz (63.2 MB) 2. Open → file manager → tap file → system prompts "Apply theme?" 3. Confirm → accept → installer extracts → progress bar ~5 s 4. Select → default apply or "Apply to lockscreen only" → choose full for full experience 5. Reboot (optional) → ensures UI cache refresh → smoother transition 6. Tweak → Settings → Themes → Koala Backyard → toggle: - Petal fall on/off - Lockscreen swipe on/off - Icon pack → keep default or switch to matching icon pack for uniform look 7. Verify → home screen shows koala icons, lockscreen swipe works, calendar widget appears on home page 8. Backup → Theme Manager → Export → save .mtz for future restores → prevents loss after OTA

Tips:

use a file explorer with root access to delete leftover cache if UI glitches persist → rm -rf /data/system/theme_cache/*
for dual‑SIM devices, lockscreen swipe may conflict with quick‑unlock gestures → disable one in Settings → avoid accidental unlocks
battery‑savvy mode disables animations automatically → re‑enable manually if you want the full effect

Pros and Cons

- Pros - cute, cohesive visual language → immediate appeal - low‑impact animations → works on mid‑range chips - built‑in calendar & step shortcut → functional bonus - dark‑mode aware → eye‑friendly at night - Cons - petal animation can stutter on low RAM - lockscreen swipe may interfere with custom unlock gestures - no official designer credit → support limited to community - OTA resets theme → requires re‑apply
