From what I’ve read elsewhere (seen some comments here, don’t remember the exact threads) the Graphene team has a specific hardware requirement that Fairphone doesn’t supply. Would be cool to see both projects working together though

If Motorola does I'll dump myPixel9 in a heartbeat... Google has too much of a hand in it..

The team behind GrapheneOS want it to be really secure so they have specific requirements that the phones from Fairphone sadly doesn't meet.

For a phone to meet all of these requirements AND still being everything that a Fairphone is would make the phone more expensive than the average consumer would be willing to pay. I know several enthusiasts (me included) that would pay for one, but there are simply just to few of us.

Graphene has a pin scrambler, so the numbers are in a different position everytime you have to enter them.

It doesn't matter. When I'm inserting my PIN on a bus or while standing or line with people behind me or something I know that anyone interested can clearly see my screen and learn my PIN, scrambler or not. Also, scrambler is not mandatory (I don't have it enabled) so Graphene OS devs explanation that "we will not enable patter ulock because it's not secure" while normal PIN can be enabled still doesn't hold.

This is actually a broader problem with Graphene OS. The devs often fixate on some minor security issues that don't impact 99% of their users at all and refuse to introduce features that they request. It's exactly the same with supporting phones other than Pixel. 99% of users would be completely fine using Graphene on a different phone (CIA is not going to hack them) but the devs prefer to directly reject all those users.

Would police threaten to kill you if you don't unlock your phone? Not likely. Would they just use your finger and say you agreed to unlock it? More likely.

About 1.5 days, 2 if I stretch it.

This is why threat modeling is important.

but what if I get arrested on some false pretenses and they use cellebrite to gain access?

Chances are they can clone the eMMC and wait for a CVE. Or threaten or hold you until you cave. If a lawsuit is your only recourse, I would expect any constitutional barriers to be ignored in practice. Your best bet is to never end up being an explicit target, which may be more difficult for certain individuals.

My threat model considers dragnet surveillance as the primary threat, so I'd compromise on surviving dirty maid type attacks in favor of reducing the information my device gives out.

Obviously if your device is being actively exploited, you cannot be private. But your security requirements increase greatly if your data footprint indicates to them that you warrant targeted scrutiny.

Or you have a funny picture of Vance on your phone and immigration doesn't allow you in

political dissident, activist, or a member of a marginalized group

or a journalist or a politician. Vast majority of people aren't any of those and don't have to worry about cellebrite. Most people here that talk like Graphene OS is their only option really just need deGoogled device, not the most secure phone in the world.
