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?

Was it perhaps unlocked when you lost it?

I know I’ve set my phone down unlocked a few times; particularly at work (in a warehouse).

Unless you have it set to never lock its not possible. All phones lock automatically after 30-60 seconds by default.

Unless a program is keeping the screen unlocked, like a YouTube video…

Do you frequently just leave YouTube running?

Gonna need to know more. What method do you use to lock your phone? Is it rooted?

Also: did they return the phone to you, or to your friend? Could it be your friend who went through these apps?

Fingerprint and pin code. They left the phone at a store nearby and I went to pick it up

It might have been the fingerprint sensor. They can be fooled. Mine occasionally thinks the inside of my trouser pocket looks just like my finger.

Is your pin simple? If you hold your phone up to the light can you see the smudge marks where your pin usually goes?

Do you have people set up as emergency contacts via the lock screen?

GrapheneOS also has this cool feature called Scramble PIN Layout to try and protect against guessing the pin from fingerprints on the screen.

Odd suggestion, but do you still have their contact info? Could you ask them? 😄

You could also send them a small thank you gift and ask them with that, so not to make it seem like you’re accusing them of anything

It’s a reasonable request, you could say that you need to keep your phone secure for work, and while it was great that the stranger was able to get it to you, you’re following up on if there is some bug you need to look into


Unrelated, it might be good to set up a “If lost, call ____” type message. If you don’t have another number, email also works.

Yeah. Definitely setting that up now haha. They used my phone to call my contacts, so I don’t have their number

Do those contacts happen to be your ICE? Some phones will allow those from the emergency dialer without unlocking. Don’t know about grapheme.

Graphene has and emergency dialer, but you can’t call my contacts from it.

Does your phone have a physical SIM and if so are there any contacts stored on it?

Yeah, but the calls were from my phone, so I think they would have to open it

They could’ve swapped the SIM to another phone though? Assuming you’re rocking a provider default PIN

But again, the calls were placed from his device, and other apps were accessed.

Maps and signal is like they were trying to contact somebody and see where you lived to return the phone. Banking is weird since you can’t do anything without biometric anyway.

I think you got it backwards - OP was checking those apps to see if they had been accessed

nvm I got it backwards

They mentioned checking app usage, so the person who found the phone opened those apps

Yeah. They were accessed while the phone was lost
