Thank you for your investigate and support me.
For a TC#7717582:Time after the work space locks that it can be unlocked without the password (Android 2.2 +, iOS 5.0 +) , I recheck on this test case and found this specific for Work Space locks not Device locks
So, I blocked this test case with no option on UDS 10.2.4
Could you please correct me if I am not right?
