> How do the thieves get the contact details of the person whose phone they stole to fish them?
If the phone is set to display notifications when locked, you can see the usernames of friends of theirs in notifications on the screen.
I found a locked iPhone on the ferry one time and saw Snapchat notifications from their friends on the lockscreen. I sent a message request to one of the users on the notifications, and told them that I found the phone on the boat and that the owner of the phone should contact the ferry company to retrieve the phone as I would hand it over to the crew of the ferry.
Similarly, if your goal was to be a thief instead of being helpful you might keep an eye on the Instagram notifications of the phone, and then cross-reference friends of those people to figure out who owns the phone.
