The other day my phone (a OnePlus 3T) fell out of my pocket on the bus - only noticed when my music cut out. Got into the office and opened up Google's find my phone and left a message on it.
Phoned the bus company and they were not at all helpful however I was able to track the phone in real time. I honestly thought it was a gonner but since I have disabled bootlocker unlocking in Android I knew it was a brick to anyone else (another used-to-be flashaholic). Saw the bus coming back on the map so waited at the bus stop and asked the driver. He handed me my phone and said a girl noticed it when it started ringing and handed it to him (wish I knew who she was to give her a reward for her honesty).
I'm very greatful - even though my phone was fully backed up I was not prepared to be buying another OnePlus that day. Device security is a massive bonus of not rom flashing.
