In a collaborative effort, Apple and Google have developed an industry-standard detection feature called “Detecting Unwanted Location Trackers” (DULT) for Bluetooth trackers. This standard allows users on iOS and Android devices to be alerted if an unknown Bluetooth tracker is monitoring their location.
If Android could stop “warning” me to enable Google Play services 8 times a day that would be great.
If you have a Pixel try running GrapheneOS.
