If you can get logs that show the unlock time and format it was unlocked with. Say fingerprint, and the GPS location/satellites the packets were going through you could theoretically prove you were within that area with the phone. In practice though… Dont know if you could get the location data supenod from the ISP. So it’s probably be on you to acquire the location data using something like googles location data. You can generally check it by going to Google maps, click your icon and choose timeline:
You can tell it to delete that data and set the retention period. Otherwise it will keep it for years if I remember correctly, I reduced mine to a couple weeks.
