Hello dear
from the above mentioned description it seems the child is showing behavioral problems along with aggression. The aggression could be due to the hormonal changes she is going through as she has entered the adolescence. For behavioral control try consulting a clinical psychologist for counselling on behavior management for both child and the parents. You can either book online consultation or meet in person with the psychologist for the behavior management. Try fixing the time spent of phone with her and not provide her with all the time.
