First time, I was sitting next to him while he was on his phone and I reached over him to grab something and he yanked his phone closer to him.
Second time, he was about to show me something on his phone and I moved closer and looked at his phone and he scooted back.
Third time, he was coming out of the bathroom and his phone was ringing, I picked it up to tell him who was calling and he ran over and yanked it out my hand before I could even say anything.
