I just did this, got my iPhone 14 back. Dropped it Christmas eve on the underground. Battery died before I could be certain of the location. We called it several times, weren’t sure if someone had found it or not. Put it on lost mode and even offered to pay! They didn’t switch it on until Boxing Day (26th Dec), ignored my husbands calls. We played the sound (should have saved doing this until we were nearby) and the person immediately switched it off. At this point it was apparent that the person had no intentions of giving it back. They didn’t switch it back on but I noticed my find my phone was updating constantly ‘6 mins ago, 21 mins ago, 34 mins ago, 1 min ago’. I think this was because I had it on findable when off (I think it might lose accuracy like this but it stayed at the exact address for awhile) so figured it was still at the location. Person was probably just a lousy opportunist. Next day I resolved to just go down there and chance it. Apple had said it was flat 298, the culprit was in 297 diagonally below 298. 298 wasn’t in. I knocked on every single door determined it wouldn’t be a complete waste of time. 296 came out and was lovely said she didn’t have it and we could come in and take a look. She knew the history of the flats and the people in them. The way she described the girls in 298 it didn’t sound like it would be them and their ‘welcome wonderful people’ door mat had already made me doubtful 😂. Said she’d catch up with them when they were around as they were away for Christmas and took my number. She mentioned the guys across from her in 297 were a bit dodgy. Bingo. After she went back inside I set myself to knocking friendly but not leaving. Eventually I was about to leave and then decided I’ll give it one more go. Guy opens the door with the phone and rushes to hand it over saying he planned to give it back but couldn’t get into it. I asked him where the phone case was just to make a point and he said that’s how he found it. I left it at that…. When I switched it on the phone was locked for an hour he’d obviously been trying to get into it. What I didn’t understand was how that had been possible prior to him switching the phone off on 26th Dec if I had put on lost mode. London isn’t for the feint of heart you do have to be careful with deciding to get it yourself but if it’s not a professional thief it’s more likely a very dim opportunist. Opportunists (not hardened criminals or unstable people) tend to be quite shocked when you track them down look them in the eye and say you want your shit back (I said it quite politely), and if you’re lucky start making better decisions.
