Migration and signing

Package: io.github.aureliomo.prismlock. Version code: 20.

• Disable the old com.fpring.samsung module before enabling PrismLock. Settings
  do not migrate between those packages. Do not enable both modules or RingPrint.
• This APK uses a dedicated release key. If you have a debug-signed PrismLock
  installation, disable it and uninstall it before installing this APK. Uninstalling
  removes its settings. Future official releases will retain this signing key.
• SHA-256 signing certificate:
  6e89f50c348d5857f85476d77622ef6c39334ae895661506a55c63a98b06c850.

Status and limitations

This is an experimental prerelease, not a stable compatibility guarantee.
Research used a Galaxy S23 / SM-S911B running a custom One UI 9 / Android 17 ROM.
Other firmware is unverified. The latest Aqua fix and AOD behavior require physical
lockscreen acceptance. Build, catalog, APK signature and alignment checks passed;
these are not proof of sensor behavior. Keep a way to disable the module.

The module changes visual resources, not authentication, enrollment or sensor logic.
It does not restart system processes automatically.
