What is the most acceptable way to monitor on another phone?

Question

Android

The task is simple - the child has a smartphone, and I suspect that something that is not necessary may be happening there (drugs, extortion, etc.).

What is the best solution to make it so that I can see (and preferably hear) everything that happens on his smartphone on my smartphone?
Given that I have access to his phone - what to set up there, what you need - just how, yes, simpler, so that he does not understand ....
MB packages, if anything, unlimited.

Answer 1

If there is no trust between you and the child, then nothing will help.
And covert surveillance will only make things worse.

If MTS, that is, the advertised "MTS-Search", but it eats the battery - if not in itself ... Take the child's body, connect it to the system, an SMS will come (on the child's body) - confirm. That's it, the system monitors the position and allows you to "listen" to it with a microphone and "see" it with a camera (I haven't tried it myself, because the application is harder, but I use the basic functionality).
Yes, no one followed us. At the age of 12, I went to my grandmother on the other side of the city and only upon arrival (and it was two hours by transport) could I call - if they would give me a kopeck piece. But we lived in another state, where money did not play a special role. And in the current one - pedophilic hysteria, on which scammers are trying to make money ...

1. You are afraid that the child suffers garbage in his spare time (sex, drugs, rock and roll) - explain to him that there is a time for everything.
2. You are afraid that the child may be involved in all sorts of garbage (sex, drugs, sects) - explain to him what is good and what is bad.
Your task as a parent and educator is to COMMUNICATE with your child, and not to monitor him 24/7.
