should've just taken the phone, decked him and dragged him to the cops, the evidence is right there. deleting is meaningless, it's easy to recover deleted shit.
Breaking the phone would put her in trouble, because then there would be no proof of what the perv was doing.
Sun Jing should've dragged him + the phone straight (heh) to the police.

Unless she's literally heavier than an elephant the majority of the device, and the memory especially, will be intact. Stepping on a phone on a flat surface is probably the worst way to try and destroy it. And it's fat chance that cops would be more likely to believe one guy as opposed to not only one but two girls.
