Losing your smartphone can feel like losing an appendage, so when you find an unattended phone on the ground, it is natural you would want to do the right thing and return it. But in the age of personal identification numbers, facial recognition and fingerprint locks, it’s hard to just call the owner and give it back. Before you turn it over to the police and hope for the best, there are a few tricks you can use to return that phone. You can check the phone physically for contact information – sometimes people put it inside the case or even on the battery cover. You can also try to talk to the phone’s voice assistant like Apple’s Siri, Google Assistant, or Samsung’s Bixby even when the phone is locked. If all else fails, you should take it to the carrier or the police.
