The main reason I didn't go with this approach is because if they decide to take it, I'm out of a phone. If they take my cheap burner, it served its purpose.

But, to wipe a computer, you have to delete, then write new information over it. Deleting just deletes the references or whatever to the information.

It seems my phone supports backing up through the Google account. So no local backups and only some apps appear in the list. If it's the same as when changing to a new phone that's pretty inadequate.

The question is what to put in the zip. Do you have to use each app's backup mechanism (if it exists) and gather the files yourself? This works I guess but it's very time consuming.

I heard about that. Seems like the case would be thrown out but I didn't follow up on what happened.

If we are going to name something and say it's a problem like there is something that exists elsewhere, but not giving information about what that solution entails is not constructive nor useful. Did graphene make the claim they have resolved the issue? Has anything else? If not why single it out? If it's one of the better options out there at least fighting towards the goal of being more secure and it does exactly that then why the hate?

For as many people there are blindly slobbing all over grapheneos knob there are an equal amount of more blind haters.

While there is no currently not a complete solution officially released and on by default from grapheneos it does however, include:

• strict IOMMU isolation on the hardware level which restricts various radio firmwares into restricted memory spaces which prevents a rogue radio from reading and writing memory.
• firmware sandboxing and hardening which is additional firmware and other memory safe mitigations to prevent buffer overflow attacks and some other attack vectors
• per-app and system level toggles for radios
• baseband isolation verification making use of the hardware attestation tooling that verifies device firmware so that you can't rest easy that it's not been tampered with or modified with including at boot.

The issue is right now isn't graphene or any other competitor but a radio hardware issue to resolve further, which means no one has much better if at all. So while not complete or perfect it is however as far as I know one of the best attempts out there. For the US at least the FCC must explicitly approve whatever new hardware design they come up with using whatever hardware partner such as Motorola for radio fabrication. Currently Motorola Mobile (and not their evil sister company they split from who more likely does have patents) to my understanding does not have patents in this space which brings up another ma to or hurdle as the big dogs who design radios have anyone's balls in a vice grip that tries to enter it with lawsuit after lawsuit. Then we have the carriers own testing. Not saying this is impossible, but from the standpoint of graphene or any other security minded OS this is out of scope and just not realistic to ask of them. At least that was the case in the past. There is possible opportunity with the Motorola Mobile partnership, but I would not expect this in the first release.

GOS has good broadband isolation, and can actually switch the cellular radio off.

Yep, specifically for entering providing the duress password for the ICEstapo agent to into his phone that had GrapheneOS on it to wipe it before handing it over to it was taken by the authorities.

Which led to DHS/CBP prosecuting him for "evidence tampering".

He's going to be prosecuted, whether he's found guilty and what he's found guilty of is still TBD

No. They already had him and the device, and he gave them the wipe pin when they asked him for the unlock pin. That's destruction of evidence.
