So basically the answer you're looking for, is NO. Get out your key, hoddie and go for a little walk...
There is an app for reporting illegal parking and other problems like illegally dumped waste etc. Here is a link the the android version: https://play.google.com/store/apps/details?id=egovframework.tcpotal.mobile.lur
Seoul has its own app but it's pretty similar: https://play.google.com/store/apps/details?id=kr.go.seoul.seoulSmartReport
In Korea, go find a store called Alpha or Morning Glory. Each of them will have the necessary craft materials you need to break the spycams once you find them.
Also here's a korean government incident reporting app for android but of course the best avenue of recourse is to find a subway worker or police officer and lead them to the device's location.
