D1529160133891, Jun 28, 2018 : If anyone else seeing the large amounts of files called hci_bt_snoop logs getting information created in the BT OEM folder. I found it was Bluetooth logging. I checked in the Development options and it is turned off. So i turned it on and rebooted then turned it off again and again rebooted, as soon as I start using BT devices the logs are created again. This must be a bug.
