When it comes to scanning and tracking paired Bluetooth devices, Android devices are completely different from iOS phones. Historically, more files were accessible that tracked connectivity in older Android versions. We used to be able to track connectivity to Bluetooth, NFC, USB, and more within /data/com.android.connectivity.metrics/databases/events.db. This file is no longer present on the Android devices we tested. In addition, connections to a car via Bluetooth exist all over the Android device. If you are trying to determine if a user was driving hands-free, you have your work cut out for you.
