Maybe someone has mentioned it but, have you considered the possibility that he is testing you? Pushing your limits to see if you will give up on him? He's eight so he knows stealing is wrong but he probably doesn't grasp the full scope of what will happen if he keeps doing it. Persistent bad behavior from an adopted kid though, it might be time to seek a therapist and try to head off some of these issues before it's too late. Also, my three year old has a phone. No active plan but she is allowed to us it and pick games to play and download. She watches TV when she likes, only shows I approve. I'm strict on what she is allowed to watch, not on time limit. Your policy is too stringent and your child might be getting bullied because of it.
