Have you ever found someone else’s misplaced phone? It happened to me once several years ago at a large outdoor concert. It was a nice handset but without the use of today’s recovery / tracking apps, I had no way of finding its owner. Fortunately, the phone rang as we were exiting the venue and I was able to meet back up with its rightful owner. Such a coincidence is rare and considering that most smartphones these days are (or should be) password protected, doing the right thing with a lost phone can be difficult.
