i have an idea could reduce phone stolen and its a bit tricky that the thife usually when they snitch a phone all he care about it to run in a safe place and then try to find a away to open stolen device .. but how we convince the thief to return phone instade of going to jail .. the idea its all about when the thief enter pass code incorrect integirated with ai camera can take a pic for thief face without even to be aware of this like all he will see lock screen background but at the same time when camera take a clear picture to thief send it automataclliy with owner on his email and at the same time the owner will save on his phone a message only appear automaticly when process is done and camera caputure his face .. this message simply will show his picture and informed him that your picture now has been send to the owner of this phone so call him on this number you set and returned back within hour or your picture will go to the police .. i think this is really will reduce phone roppery
