RF triangulation exists but requires either law enforcement + carrier cooperation or specialized equipment you probably don't have.
GrapheneOS doesn't include Find My Device because that's Google's surveillance infrastructure. No backdoor location tracking—that's the whole point. Privacy has trade-offs.
The good news in this case: GrapheneOS or not, if the radios are on, the phone is transmitting.
Your phone is still transmitting even when idle:
- Cell tower pings every few seconds (network registration)
- IMEI/IMSI broadcasts during those pings
- WiFi keepalive packets if connected
- Bluetooth advertisements if enabled
- Background RF noise from oscillators and processors
If the phone is nearby, here are some things to try:
If you've got WiFi on and it's connected to your network, check your router admin panel for connected devices. You can also use arp -a or ip neigh to see if it shows up on your local network, or try pinging it.
Bluetooth on? Use a BT scanner app on another device. Walk around and watch the signal strength. Range is about 30 feet. I've found lost earbuds this way.
Hope this helps!
Thanks Ava. This is helpful for future reference 😁
The phone has been located -- it fell out of my pocket during the car ride home (a couple at the train station offered me a ride bc the taxi phone number wasn't working and the Uber app download with Aurora wouldn't open).
They were local, seemed very nice and we exchanged business cards (he works in IT).
He sent me an email saying he had my phone and asked me to connect and retrieve it. I replied via email and voicemail yesterday.
Waiting to hear back 🤞
The phone is used for providing numbers to website and OTP.
I had it with me for travelling to access accounts.
I think the only app on the phone is Amethyst... I'm assuming I can't log out of that remotely.
