Hi,
I guess I have the same problem.
I have Android 2.3.6 Gingerbread. I set, in the Anti-Theft definitions, :
Lock phone unticked.
Deny phone setting access ticked.
But in my avast web site, when I try 'Lost', which should initiate the same actions as a SIM card change, I notice that I can still do everything with the mobile phone, including unistalling apps, even the Update Agent (I guess this is the Anti-Theft)! This is no good!
What is the "Deny phone setting access" actually supposed to do?
Thanks.
