I really do like the "Stop #Hacklore!" recommendations from https://www.hacklore.org/
However, in my opinion, they do ignore the gigantic #tracking threat on #privacy by the #Bluetooth tracker industry and the Multi-Billion-Dollar-Business of #DataBrokers sharing this data when they say that "turning off Bluetooth and NFC" is an "outdated advice".
For NFC I can not tell.
Unfortunately, most retail chains are using Bluetooth tracking and share their tracking with basically all others.
So my recommendation is: turn off at least Bluetooth any time you're not actively using it! Furthermore, I'd recommend people to randomize their #WiFi MAC address for unknown networks as well in their settings.
Modern Android has a neat feature to turn off Bluetooth when you're not using it for xx seconds/minutes. Use that and be aware that if you're walking through streets or shopping areas with your active BT headphones, you're being tracked all the time.
