Lost phone in hongdae, fly back tomorrow

Hi there, I’ve been on a pretty lovely short trip in Korea, and unfortunately last night at around 9pm near the Hongik Station exit 3 I lost my phone.

When I was walking out of my hotel, I still had it, I checked the hotel cctv to the furthest radius I could. I literally walked at 9:04 and realized it was lost three minutes later. I returned to the hotel looking for any sign of my phone right way - but nothing.

I’ve asked the shops nearby in those 70 or so meters, and none of them have access to either outside cctv or cctv at all. I’ve filed a report to the lost and found as well. Find my iphone doesn’t work. Does any one have any other tips? I leave tomorrow :(

Eg is there a korean forum I could submit these questions to?

Thank you so much
