    Find My Device is completely useless until the device is unlocked. As long as it is rebooted and not unlocked, there is no way to detect its location. Since most phones (if not all), use an encrypted filesystem. With such, no service can’t start if the device isn’t initially unlocked after reboot, including Find my device.

    This isn’t only a issue with Google’s implementation, it’s the same with other implementations to.

      Android developers can specify that their apps need to run before the pin is entered, via direct boot mode. This is how alarms still work, even if your phone takes an upgrade overnight, and restarts automatically as part of that process.

      I can’t say whether Google’s Find My Device currently does this, but there is no technical reason it can’t.

      Pretty sure this isn’t true. Afaik, you can exclude files from encryption on Android. This is also why you see your custom wallpaper before unlocking the phone.

      As far as I’m aware find my on iPhone can work even when the phone is off, this is because the phone kinda acts like an airtags where enough information can be exchanged securely.
