e711b3277e
This change disables the FaceSettings Confirmation setting if a sensor is convenience. This is due to the fact that convenience strength sensors can't be used by BiometricPrompt (so this setting has no effect.) Test: Verified this setting shows depending on whether or not the sensor is convenience or not. Fixes: 204137656 Change-Id: I88daf9f12b76d06697275161385f463fb88e0f3a
