I think Clicking Bluetooth doesn’t turn off ble which is possibly what is used for tracking. Phone is still tracked despite it and it turns on automatically after 24 hours from what I remember..
The Amazon app probably has microphone access enabled because you allowed it for Alexa in the app at some point. None of these apps have access automatically. You allowed it at some point and I’m sure you were told why at the time and have forgotten, or didn’t pay attention.
Thanks for the tips! how come when I reboot my phone it's asks for a passcode to unlock my phone instead doing with with face ID? Does anyone know or how to change this? it's is very annoying 🙄
