A:Answer Greetings Gracie, thank you for finding the opportunity to ask us your question about the Samsung Galaxy Tab A8. If your tablet is not recognizing your PIN, pattern, password, fingerprint, or face unlock, rebooting the device or entering Safe Mode can help solve the problem. Sometimes you may be prompted to try an alternate method, like your password.
