Unless the next best thing makes you think you are already achieving the "perfect solution" for what you think you care about, but in truth does not. I'm not a mobile phone security expert but my feeling is that in the case of GrapheneOS - which target is probably high-profile people at risk of state actors et similia attacks - a zero-day in the closed source firmware from Qualcomm will probably screw you anyway. I u…

fyi a Cell Site Simulator can masquerade as the legitimate telco operator and push type 0 messages to the handset. What that means is they can push malicious settings and configurations (Definitely) and probably malicious firmware to the handset at will. They don't need to code this, they buy the software packages from the usual suspects. Adversary simply needs to put a drt box or a hailstorm or what-not close enough…

They can and do, see above. But I don't see how hardened_malloc is related to the baseband doing DMA.

One of the only big downsides I've noticed with GrapheneOS is that several banking apps don't work with it at all thanks to being tied to Google's verification ecosystem. Luckily I have hardware 2FA keys from my bank so I can authenticate using that. It also slightly decreases the suck-factor from whenever the phone decides to fly off down a drain. This may not be the case for you, so do your research on what you nee…

What about the small matter of having to purchase a Google phone in the first place?

Most anti-google move: buy a second hand pixel, they receive no revenue on the device which is (assumed) already highly subsidized by google so that they can profit off users' data, then you use their subsidized hardware without running their spyware OS. Google only loses money in this scenario, it is a great protest.

I've used GrapheneOS on a Pixel 3a, 5, 8 and 10 Pro so far and it's worked really well. I couldn't imagine going back.

The only things I'm missing (which don't exist in other OS'es either):

- Being able to configure contact scopes in such a way that the app in question only gets access to the phone numbers of the contacts belonging to the label I specified, e.g. "WhatsApp", nothing more. Yes, one can of course add contacts' phone numbers to the contact scopes "by hand" but 1) there is a limit on the number of contacts/phone numbers configured this way, and 2) AFAIK there is no way to back up that list.

- Being able to install browser extensions in Vanadium.

- Being able to configure multiple VPNs at once, e.g. for Tailscale, ad filtering, blocking HackerNews during times when I should be doing something more productive :) etc., especially since the Vanadium browser doesn't support extensions (see above). I was hoping that the Rethink app might implement something like this (https://github.com/celzero/rethink-app/issues/1047) but it doesn't look like it's coming and it'd probably be much better to do this at the OS level.

Been using this for about a year on a p9 pro. It works very well. I hear the google tap to pay does not work, but I've never tried it. However Vipps with their tap to pay works fine. BankID works but not with biometric login, which some things require IIRC. And for some reason DnB private works fine, but you are not allowed in on the corp app. It's mind boggingly stupid that they lock down apps like this, when you ca…

I was the one that submitted the DNB Bedrift app report to the sec dev repo! I contacted DNB but they never responded to my email. I wonder if we can find a dev? I believe that's how the private app got fixed. Want to use Vipps tæpp so much but I have Nordea for private and they don't allow it on their cards, for whatever godforsaken reason.

Ah. Where did you send this in?

I wouldn't mind sending in a complaint to both BankID (allow biometric login) and of course DnB corpo edition.

We need Linux OSes and phones to catch up to really break free from this duopoly. Only when there is enough traction, essential infrastructure like banks will start supporting Oses like that. It's a chicken and egg kind of problem.

Android is a Linux OS and is eons ahead anything that would sit on top of "GNU/Linux" userspace. Why start from scratch?

I think that the main problem is that android has a lot of weird modifications that are not consistent with the rest of linux distros. The user data is suddenly in /data instead of /home, theres no package manager, no systemd (for better or worse), and there's hella lotta security gotchas, for example call recording is impossible without root as far as I know. I'm not saying that Android is not hackable, but it's a different type of hackability than desktop linux, you have to learn it all over again and in my opinion it's much harder to master than desktop linux.

I've been on ubports for 3 years and while it also has some weird caveats like read only rootfs, no working package manager (due to read-only fs. however ubports has pretty cool support for lxc containers where you can use apt). Due to chronic lack of time I haven't been able to sit down on my phone to play with it a bit (for example id like to install waydroid), but it seems a lot easier than android. For example, while there isn't an app for call recording, some guy worked around it by writing a systemd user service as a workaround[1]. This is exactly the type of thing I'm thinking about when talking "linux phone".

For me as a linux user, the difference if ubports was a human, I'd think that perhaps they were sick, whereas if android was a human, i'd shoot them in the face :)

While I admire GrapheneOS and its goals, I feel that until we free the proprietary baseband processors and their RTOS from the grips of Qualcomm and friends it's a pyrrhic victory, at best .

iirc Graphene is in talks with an unnamed HW vendor to make a grapheneos specific phone. They refer to the vendor as someone who makes phones and you've likely heard of, but haven't given any more info otherwise.

Yeah spot on. I think this is the only thing that's been announced so far: https://www.androidauthority.com/graphene-os-major-android-o...

Oh! Sorry, you described the current state of things so well I assumed you were close to the project.

Here is the github repo where banking app compatibilities are tracked: https://github.com/PrivSec-dev/banking-apps-compat-report

Break free from Google and Apple by buying a phone from Google /s

I commented elsewhere but GrapheneOS on Pixels actively siphon resources from Google and is arguably a good protest against google.

They subsidize Pixel hardware (to incentivize users to adopt their spyware OS), you (buying used obviously) take their subsidized hardware and do not repay them by using their spyware, replacing it with Graphene. Only google loses. Their hardware is technically very good otherwise (in fact no other hardware fits the strict graphene security requirements).

Same with Lineage OS, may daughter has an old Samsung with Lineage on it and the Wallet app doesn't work because the phone's been rooted.
