Shared here for public benefit.

Before going to a protest, demonstrators or observers should note that their cellphones may subject them to surveillance tactics by law enforcement. If your cellphone is on and unsecured, your location can be tracked and your unencrypted communications, such as SMS, may be intercepted. Additionally, police may retrieve your messages and the content of your phone if they take custody of your phone, or later by warrant or subpoena.

Source? EFF says airplane mode is sufficient per the article

[–] GreenKnight23@lemmy.world 6 points 9 hours ago (2 children)

so you're going yo trust the government funded org to tell you how to not be tracked by the government?

better yet, you're going to trust the company that actively works with the government under national defense that wants to track you to protect national defense?

no thanks. I'd rather be safe than detained.

Until I see a shred of evidence that airplane mode doesn't disable the radios, yes, I'm going to trust the manufacturers, the EFF, and my background in EE

[–] dhork@lemmy.world 2 points 7 hours ago

I tend to agree (and also an EE). Airplane mode isn't a total panacea, though. It just disables the cellular radio. While it also disables the Wifi and Bluetooth, those can always be turned back on, even while Airplane Mode is active. A motivated state actor can absolutely track via Wifi or Bluetooth. (Possibly even NFC, but the range on that is so low that I think it would impossible to do without seeing what is tracking you).

Turning the phone off is the best solution if you want to keep rhe phone on your person. Guaranteed that all possible avenues for tracking is off, and also has the advantage that even if the phone is seized, the latest phone OSes require the passcode before doing anything at all when they first power up. Even the Police are limited in the data they can get off a phone that has just powered up and is asking for the passcode.

cool. you do you then.

I'll keep doing whatever I need to ensure my freedom by not trusting government or corporate guidelines.
