She needs to be punished like you would for a younger child. Make a list with her of things she can can't do , can do and when it's acceptable to do it. If she does X, Y or z the her phone is taken off her for the day. No TV, no whatever. In turn if she does what you're asking reward her. She needs to change the habit. I do agree though. She shouldn't be touching your DD. What will happen if she's really angry one day?
