I’m running Graphene on a Pixel 6. I lost it and someone opened it somehow and called two of my contacts to give it back.
I’m a bit confused how this even happened. When I got the phone back, they were going through my contacts. I checked app usage stats and they went through a banking app (not missing money), maps, signal, etc.
Is there a way to figure out how they even unlocked my phone?
They clearly seemed to mean well. Maybe you can ask?
I imagine you may have lost your phone while it was still unlocked. It’s possible that there’s a Graphene lock screen bypass out there, but I doubt someone with such knowledge will use it to return your phone to you. Most “hacker” style lock screen bypass I imagine someone wanting to return the phone will do is checking for smudges on the PIN area of the lock screen and determining the code from that.
To combat someone unlocking your phone through smudges, you can enable PIN scrambling.
