When I send the lock code to my phone.
Go Sms will show the text. 2222 Lock as and example. Also, it shows up in the notification bar.
I have phone rooted if that helps.
other issue is the protection behavior they do not seem to work or I am not understanding it fully.
I am able to access the device administrator to disable anti-theft even though I have my settings set to disable access to the phone settings.
