Not good enough. Phones can figure out its location using gyroscopes and accelerometer, then if at any point in the future, you remove it from the faraday cage, your entire movement logs are transmitted.

This is plainly false.
The error stack-up from the imprecision of a phone's MEMS sensors would make positioning basically impossible after a couple of dozen feet, let alone after hours of walking around.
There are experimental inertial navigation systems that can do what you describe, but they use ultra sensitive magnetometers to detect tiny changes in the behavior of laser suspended ultra cold gas clouds that are only a few hundred atoms large. That is not inside your phone.

You won't have much of a choice when FEMA is gone. I mean, less and less people will have homes there anymore.
Right, because nobody lived here prior to the existence of FEMA.
I, for the life of me, cannot understand how people can look at the history of what our, and most other governments have done, and then say, "Hey, you know what? We need more of that!"

Police issues a dispersal order, but blocks all routes to safely leave the area.
Congratulations, you will now be charged as having committed a crime and good luck proving in a court that there was no realistic option for you to leave.
Also police seizes your phone. Congratulations now they access your data and either go after people you have had contact with or they claim you to be part of a criminal organization as they pin other charges on people they found a connection with.
I doubt they will find anything of use. The most powerful thing I can do is slow them down. It's the best use of my privilege

Lawyers operate in courts. We don’t have due process anymore.
Then as I said we're already cooked. But also that is demonstrably false anyway. Our judiciary is under heavy threat, but still functioning

That gives me a good idea. A week before the protest buy burners, use them frequently near republican supporters' house, go to a protest, use your phone all the time in the protest, dump them near the police, let them enjoy the fruits of the regime they supported.
Diabolical.
In theory, of course. Definitely just in theory. -

You seem to know a lot about this. I'm just generally fascinated by this method of tracking. Would the sensors ever become accurate enough in the future? Or is there a limit to their accuracy due to physics with a small sensor?

Yeah, it's not like there's a reason fewer and fewer insurance companies will write a policy in that state every year. It's not like the property insurance rates are the highest in the country.

Cool...
This one goes out to all the small government, privacy loving, Republicans out there, supposedly hating invasive big brother tactics and representing the values of the American heartland.
Would be much appreciated if you could have a word with your people about this.
Green lasers. Everybody should have one.

Gotta clean and sterilize them.

Having a small faraday bag around is useful too, that's what I do.
Faraday bags do not work with 5G

That burner cant ever have connected to a cell tower when its near your house, otherwise its not longer a "burner"
Edit: Also: Beware of the possibility of there being malware that logs gyroscope and accelerometer data. Those info can be used to figure out your location, then transmitted whenever it has a chance.
Gyro/accelerometer data isn't accurate enough to do that. Small errors in the data add up and will quickly drift away from the actual location. You can use it for video game controllers, but not tracking over large distances. Edit: there's a reason the best VR tracking often uses external methods, not controllers alone.
But most phones have GPS and that's where the real problem is.

Faraday cage does not prevent gyroscopes and accelerometers from working. Then if you remove it from a faraday cage in the future, it will transmit all that movement
Since you're posting this all over the thread, I'll also have to repeat the information that gyro/accelerometers are not capable of doing that. Small measurement errors stack up and throw it completely off.

This is the sort of nuts and bolts of protesting that Americans are learning the hard and fast way.

Without GPS or tower based error correction any location prediction based on conservation of momentum in the phone will be useless before very long if the phone is moving.

My concern would be that the police would confiscate my phone. Not that they would necessarily be anything on it, but I don't want them to have my nice expensive phone. They can have this crappy cheap one instead.
Do you have a recommendation for a good cheap android phone (didn't worry, I'll run a rom) that one could get to have a "clean" phone?
I've been thinking about getting a phone that has none of my socials on it for when I go to Canada to get vaccines

It will always be a matter of "for how long?". Location from integrated acceleration is what we call a stiff problem. Meaning that any error is compounded as you continue to integrate (slight over simplification, but good enough for the point). There will never be a sensor that has zero error, so it's just a question of how much integration you can do before the errors make the results unusable.

A helicopter said all this?

Can you imagine 6 dudes with AR-15s, nothing fancy, responding that that threat? One wonders what might happen.
If gta has taught me anything is that one well placed shot from a measly handgun can take down a chopper
