It's worth knowing the age of the child, whether the act was wilfull or negligent, and whether the act was attributable to parental negligence.It likely also matters whether the classmate was playing the game as well.Finally, it's worth knowing what the cost would be to repair the phone, and what condition the phone was in to begin with. Generally speaking, the owner wouldn't be entitled to a new phone if the cost to repair were low or the phone was quite depreciated already at the time of the accident.
