I know standard Android has its base identifiers of sorts and certain apps have access to certain parts of these.
I know GrapheneOS essentially blocks some of this as well.
Assuming one is looking to utilize a device and later be able to wipe it, what sort of risk factors could one expect around the following:
- Installing Google Play Store and related services
- Signing into a Google account to utilize said services
- Using Google Fi for cellular connection, especially with a data-only SIM card (not eSIM as they are not available for data-only). Also adding in the privileged eSIM management with this and its added scope.
I'm looking around the general thought of whether the Google Fi/SIM card and phone can be linked back, if you would dispose of the card entirely and recycle it, or use a separate account entirely (most likely separate if ever at all), as well as Google play and Google account sign-in. If someone took the device, could they find whether it was the one used with a specific Google account, or does Google only see a dummy serial, IMEI, etc.?
I know some identifiers change when resetting a device, but not all. I'm wondering how much the Google Services Framework and alike have access to with that, and what all could be linked back. Unless someone states otherwise, I'll assume based on the FAQ that general user apps have access to none of this information.
