I don’t think JADE is necessarily the right approach.

I don’t really understand the situation you’re trying to describe.

he likes to ask per chat if the smartphone works ok

What does this mean? Why is he asking if he’s just going to say “the smartphone works” regardless of your response?

Your suggested response is defensive and argumentative by the way, particularly so.

I would handle this by just playing along. If he asks if the phone is working just say “yes”. If a problem with communication arises and you use your best judgement, which later pisses him off, just explain what’s happened and ask what he would like you to do next time.

You don’t actually have to to what he says, just make him feel like you’re acquiescing to his authority.
