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 37 fingerprint families and 24 touch-effect families, including Keqing, Pyro, Orbit, Pulse, Tide, Dew, Orb, Lotus, Bloom and Snowflake, with alternate color/motion styles grouped inside each family.

Independent fingerprint and effect selection with automatic saving.

Native style picker for shared designs; old selections and alternate colors remain available.

Built-in 120fps playback timelines with temporal interpolation and unchanged durations; up to 120Hz UI refresh on supported displays.

Aligned title/style columns, coalesced thumbnail loading and idle-expiring background workers.

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.

Modern libxposed API 102 integration with background configuration loading.

Recycled catalog rows and asynchronous thumbnail/wallpaper loading.

Enlarged icon glows can extend beyond the Lottie artboard on compatible Samsung renderers.

In-app GitHub update checker and installer, with automatic foreground checks.

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.
