Here’s how it happens. Your using the restroom in some place on your phone and then you set it down on the toilet dispenser because you need to take care of business down there. You leave the restroom and you forgot your phone. Some guy takes it. Assuming you equip a lock screen that says "run passwords if I forget my password again” the thief sees this and he does it. Doing that send someone you a trust a message of the exact location of it and some more. Many more things happen and it will also get the thief to look at the phone and it will then take a picture so if the guy says he didn’t take it and you find him I. The park sitting next to it, then just check the last taken photos. BAM that’s a good shortcut.
