PrismLock

PrismLock is an Xposed / LSPosed module that replaces fingerprint icons and touch effects on Samsung One UI. Choose a design from the built-in catalog or import your own PNG or Lottie artwork. Changes save automatically.

The module hooks Samsung's fingerprint asset loader instead of modifying a system APK. That is the same device-independent technique used by RingPrint: it works across Samsung devices and One UI builds, not only on one model or firmware version.

Features

Built-in library of 28 fingerprint designs and 18 touch animations. Independent fingerprint and effect selection with automatic saving. Color, black/light-mode and white/AOD variants for Prism, Vortex, Orbit and Neon. PNG and Lottie imports for light and dark/AOD modes. Separate fingerprint and animation previews with visible-bound size normalization. English interface with system, light and dark appearance. Smaller 0.8-second Aqua effect with a transparent final frame. Customization switch to pass through to Samsung's default visual resources. In-app GitHub update checker and installer. The module changes visual resources only. It does not change authentication, enrollment, illumination masks, brightness control or sensor behavior.

Compatibility

Component Requirements Module framework LSPosed with legacy Xposed API 82 support Devices Samsung One UI with an in-display fingerprint sensor Android 8.0 or newer (API 26+) Module scope com.samsung.android.biometrics.app.setting Reference device Galaxy S23 / SM-S911B PrismLock does not target a specific Samsung model. It intercepts the fingerprint resources Samsung requests at runtime, so the same APK works across One UI devices.
