Without disagreeing with anything you've said there, even if you /think/ you have nothing to hide now and happen to be correct in practice, it's a terrible assumption to think that you can count on that being true forever. Imagine you witness a murder in a restaurant, cold blooded and it's dirty cops working for a three letter institution that did it. You want to give evidence like a law abiding, upstanding citizen w…

The 'Dirty Cop is Gonna Get You' is the 'gradeschool silliness' here. It's 1000x more likely that the criminals who did the murder want you killed because you're a witness. Witness intimidation is widespread and 'default' in some communities ('snitches get stitches'), and while the 'Dirty Cop' thing does happen in reality, it happens mostly on Netflix, and there's a difference between overzealous prosecutors/cops and…

I suspect you live in a country with a low corruption index.

This seems different to those examples because it works when the phone is powered off. AFAIK neither pick up nor touching the screen have ever done anything when the phone is powered off, only when it’s asleep.

Yes, exactly. Many of the things I’ve seen mentioned in the comments, such as wake on motion or responding to “hey Siri” are waking from sleep. AFAIK, you can’t power on via motion or hey Siri.

You can wake from sleep via motion, and presumably from the perspective of the AOP, there isn't really a difference between "turn on" and "wake from sleep".

Your phone isn't actually "dead" when it shows out of battery though, since the display can still power on for another hour+. There's a reserve before you hit the true 0%.

I mean, true 0 would mean the battery couldn't ever charge again. My iPhones have consistently always turned off when the indicator is on 1%, which of course is probably 5% of the actual battery.

what?

Yep, that's not going to spark conspiracy theories and damage the brand at all, just like the backdoor they've recently put in. /s Again, why would $3T company damage its brand like that? It's not "for children" and certainly not to "find your phone". There's something going on there.

They do yearly updates, the 2022 doc will very likely have more information. Regardless, the 2021 doc has some key foundations of the technology that are worth knowing. The contract tracing docs _should_ be almost the same technology, and knowing how that works _should_ be a good start. At least, from my eyeing the OP's article as a lay person.

"They do yearly updates, the 2022 doc will very likely have more information." Sure you document such stuff before releasing it?

Apple doesn't even always document stuff after releasing it.

In some way this feature reminded me of Android's song detection functionality which is also on by default and is constantly listening in the background [1]. So now tech companies normalized that: - the mic is always on. - the phone is always on, even when it's off. (thanks to AOP) - devices are always online even when they are offline.(thanks to company-operated p2p networks like Find My or Sidewalk) What could poss…

The article mentions that the AOP is responsible for Siri, too.

> Yes which supports all kinds of functionality that people like. Just because you have a processor on or mic listening for wake words doesn’t mean everything is always being transmitted or evil is being done. No, but it means that I’m losing agency in whether or not those things can happen. That’s not ok and not benign.

The 'listen for music' feature on pixel phones is optional and off by default.

What is the use case that feature? I get an active "what is this song".
