I saw similar questions but there was no generic answer to the issue. Is there a way to determine what is turning my BT ON? I don't have rooted phone (but can ADB)

I got Samsung Galaxy S5 with Android 6.0.1.

What I did:

1. Turned off BT scanning for "fine localization"
2. Revoked permission to change phone settings to ALL apps that had one (including g services)
3. Disabled all BT scanning related things that I have found.

How to find what is turning BT on?
