zTheme
Build, convert and install custom .itz themes and lockscreens for Vivo and iQOO — right from your phone.
Features
Take a look at the list of features that make zTheme special!
One-Pass Theme & Font Install
Import a custom theme, lockscreen, or icons into the app — zTheme guides you step-by-step through applying it. Custom .ttf fonts get installed the same way, no manual file fuss.
*Some tweaks are experimental and may not work
System Tweaks
Enable widget blur, the glow effect for budget OriginOS devices, Fullscreen AOD, and other hidden features — right in the app via Shizuku, no root required.
*OriginOS 4, 5 and 6, CN firmware
Lockscreen Designer
Build custom Vivo/OriginOS lockscreens visually: link elements together, draw swipe trajectories, and preview formula results live before you export.
Full Theme Editor
A tabbed editor for icons, wallpapers, lockscreen, status bar and more — with an accent color editor and a live icon gallery.
Universal Converters
Turn a Xiaomi MTZ theme, an icon pack APK, or a Lawnicons SVG set into a working .itz theme in a couple of taps.
Updates Without a Browser
New builds download and install right inside the app, with an automatic fallback if anything goes wrong.
And there's a lot more
We keep polishing zTheme, one OriginOS quirk at a time.
