capability() calls FingerprintManager.isHardwareDetected() and hasEnrolledFingerprints() without any declared biometric/fingerprint permission in the Android manifests, so this path can raise SecurityException at runtime when settings refreshes (it runs from updateSwitches() on resume). Please declare USE_BIOMETRIC/USE_FINGERPRINT in the app manifest (or use an API path that avoids this requirement) before invoking these methods.

This implementation treats biometrics as available only when a fingerprint sensor is present, which incorrectly disables the new “Enable biometrics” setting on devices that support non-fingerprint biometrics (for example, face/iris-only hardware). Since the feature is exposed as generic biometrics, capability should be checked via BiometricManager.canAuthenticate(...) (or equivalent) rather than fingerprint-only APIs.
