Job description
I will commission the development of an application / software on Android that will "lock" the phone when such a command is sent from external software (CRM). By locking the phone I mean:
- blocking making / receiving calls (except emergency calls)
- blocking entry into menus / applications (in general: use of the phone)
Such an application would work 24/7 or possibly check every few hours if the lock status is zero. If it is not, the phone is blocked. If the phone is not connected to the Internet - that is, if the phone does not send any signal within, for example, 24 hours, the application will automatically lock the phone (in case someone wants to bypass the security by disconnecting the phone).
On the external software side, we can freely send feedback, e.g. in response to the application's query we will return 0 or 1 (if blocked).
