Could you not wrap it in thin foil to make a faraday cage? If done well it should prevent any signals for going in or out.

Well also just the brown ones.

Go old school and bring cameras instead.

Source? EFF says airplane mode is sufficient per the article

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

What government funding does the EFF take in?

Mixed results. Implying: blue leadership could be doing better in that area.

cool. you do you then.

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

I'm assuming the light/dark filter gets applied before they're ever incarcerated, but yeah, plenty of pre-judgement goes on at all stages of police decision making.

Also be aware that the Georgia attorney general has declared that not bringing your phone to a protest will be considered criminal intent. They’re now trying to punish people for not having their tracking devices with them.

Just a moment...

Sure but it could just do the default thing because it just wasn't changed.

To be specific, it's not the GPS receiver, it's the fact that the car may be communicating via cell network or satellite, right?

You can turn that off, I'm pretty sure.

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.

Right, but most modern cars have that communication built in, because they use it to update firmware remotely. You can't turn it off even if you wanted to. Many car companies justify it by saying it is needed to give your location to emergency services if you use their alert button.

I would not be surprised if it can only be "turned off."
