United had lost 1-0 at Goodison Park, and Ronaldo was booed by the home fans as he walked off the field.
In the midst of the chaos, the 37-year-old hit a fan’s phone out of his hands.
Ronaldo has since apologised and offered to have the boy a chance to attend a match at Old Trafford, while police continue their investigation.
But Rangnick has broken his silence one week after the incident.
He said: “No. I think he apologised in public on social media for what happened.
“As far as I know there is still an investigation ongoing, both from the police and the FA, but apart from that, I haven’t spoken about that with him.”
