- When finger can't be analyzed for enrollment (FINGERPRINT_ERROR_UNABLE_TO_PROCESS), tell the user to try again or use a different finger. - When timeout is reached (FINGERPRINT_ERROR_TIMEOUT), stop enrollment and ask the user to try again. Fixes bug 23546104 Fixes bug 22708384 Change-Id: I879874b53dd0d928093fab1c92d0d4d68d73be28
