A few weeks ago I found a working iPhone X on the side on the sidewalk. I thought about using siri to call a recent contact and try to get it back to the owner, but I found the language was set to Chinese (which I cannot read or speak) and I gave up and put it back on the sidewalk in case the owner came back.

In retrospect, I don't think I could have done anything even if the language was English apart from wait for the owner to call their phone. That said, I'm curious if anyone has any suggestions about how I could have been a better Samaritan.
