I see quite a few people claiming that Graphene OS is the only way to stay private on Android or that anything but Graphene OS is insecure. In this post, I will describe why I personally do not care for Graphene OS and some alternatives I would suggest.
First off, let's address the security features of Graphene OS. A lot of the security of Graphene OS comes from AOSP itself. In fact, AOSP has a very good track record. If you get malware on your device, you most likely can just uninstall it. For reference, here is the Android security page: https://source.android.com/docs/security/features
There are some Graphene OS unique security features. For instance, it has a hardened kernel and restricts access. I think this is actually pretty useful but I haven't seen a need for it much in the real world. The tightened permissions are nice, and I think that is the main benefit of Graphene OS over AOSP. It is also nice that device identifiers are restricted from a privacy perspective. However, from my perspective, you should not run apps that are bad for privacy. Running it in the web browser will be more secure than bare metal could ever be.
One place I strongly disagree with Graphene OS is the sandboxed Google services framework. They say having Google in a sandbox is more secure. It may be more secure, but it isn't going to be as private as MicroG. The real benefit of MicroG is that it is community-built. It isn't a black box like Google framework, and any data sent back is randomized. I think it is a mistake for Graphene OS not to have support for it, even if it is also run in a sandbox.
Another thing I have noticed is that Graphene OS prioritizes security above all else. That doesn't mean it isn't private as it itself is great for privacy. However, if you start installing privacy-compromising applications such as Gmail and Instagram, your privacy is quickly lost. The apps may not be able to compromise the OS, but for them to be used, they need permissions. To be fair, this is a problem that is not unique to Graphene OS, but I think its attempts to be closer to Google Android make it more tempting for people to stick to poor privacy choices.
I think other ROMs such as Calyx OS take the ethical component much more seriously. Unlike Graphene, it promotes F-droid and FOSS software like MicroG. Graphene purely focuses on security while Calyx OS focuses on privacy and freedom. On first setup, it offers to install privacy-friendly FOSS applications such as F-droid and the like. I realize that MicroG is not perfectly compatible, and some people need apps, but I think alternatives are going to always be better.
One of the most annoying parts about Graphene OS is the development team and some of the community. They refuse to take criticism and have been known to delete any criticism of Graphene OS. Not only that, they have a history of trying to harm any project or person they don't like.
Here is a page that isn't written by me that sums it up: https://opinionplatform.org/grapheneos/index.html I think their take is fairly extreme, but I agree with them in many ways. I also understand how upsetting it can be to be censored.
GrapheneOS never claimed anything different, in fact, on their website, they say:
GrapheneOS just adds to the already solid security of AOSP. The security improvements are listed at https://grapheneos.org/features. Also, a bunch of AOSP security features originate from the GrapheneOS project and were merged into the AOSP codebase. Just so you know.
This is not the kind of stuff GrapheneOS is defending against. GrapheneOS specifically focuses on persistant malware by improving Android Verified Boot along with other security mechanisms.
There is a real-world need for it. Hardening the system against attacks from commercial/state-sponsored spyware like NSO Group's Pegasus or Cytrox's Predator requires extensive defense-in-depth improvements to the entire operating system stack. If you want to see an instance of actual, real world kernel-level exploits against mobile devices, look no further than the case of UAE-based human rights activist Ahmed Mansoor. In 2016, his iPhone 6 was attacked by the UAE government, using the Pegasus spyware made by an Israeli cyber mercenary company known as NSO Group. The attack used a payload delivered via SMS, which contained a link to a malicious website. If Mansoor would have clicked on the link, a zero-day exploit in WebKit CVE-2016-4657 would have been triggered. The attack used the Trident exploit chain, which if successfully deployed, would have remotely jailbroken Mansoor's iPhone, using, CVE-2016-4655 and CVE-2016-4656, two kernel-level exploits present in iOS at the time. There are very good reasons for a security-focused OS like Graphene to make substantial improvements to all parts of the Android operating system, including the underlying Linux kernel.
Some apps simply can't be run in a web browser, and they require you to install them on your device. GrapheneOS significantly helps with running untrusted applications in a safe manner, especially when using the hardened user profiles feature, which essentially makes you anonymous (in regard to device and profile identifiers, it is still important to use a VPN/Tor, etc.)
Claiming to be a secure OS while repeatedly missing important AOSP security patches is pretty misleading, and giving the user a false sense of security is not quite ethical. GrapheneOS is very minimalistic, and the user is free to choose how they want to get their apps. Although I support the fact that CalyxOS bundles apps like Signal and F-Droid, some other users might see it as unnecessary bloat. I prefer Graphene's approach of only including strictly necessary apps, and leaving the rest up to the user.
A secure base device/OS is what enables privacy and user freedom. It's not like GrapheneOS is taking away any of your privacy or freedom, in fact, it is very private by default, due to its minimalistic nature: https://grapheneos.org/faq#default-connections
The main problem with microG is the fact that it needs to run as root, whereas Sandboxed Play Services uses a much more secure approach for getting Google services, while still preserving user privacy.
Not quite sure what you mean. The GrapheneOS team just really cares about good, high-quality, secure and complete code, and they like to call out any projects that don't follow these principles. Just like Linus Torvalds has a history of rejecting poor, low-quality code, in order to keep the Linux kernel codebase clean and easy to maintain. They're just focused on quality, and if people are offended by that, they should really overthink their own approach to writing and maintaining code.
That website almost feels like a shitpost. Any source that tells you to "Avoid [GrapheneOS] like the plague", but claims that LineageOS is "Good to go!" shouldn't be taken seriously. Recommending people a highly insecure OS that doesn't even allow for locking the bootloader is straight-up user-hostile. I could go through each one of the "arguments" brought up against GrapheneOS, but they are so bad that I don't feel like wasting my time on a whole bunch of them. But let's just go through one example:
https://opinionplatform.org/grapheneos/strcat-tactical-licensing-20230409.html
This post suggests that GrapheneOS is somehow against open-source software, and shows the following chat log:
Bromite literally used Graphene's code and then changed the license to prevent GrapheneOS from using any of the Bromite code. In response to this anti open-source move, GrapheneOS changed the license for their Vanadium browser from MIT to the more restrictive (but still FOSS!) GPLv2 license. But apparently GrapheneOS is "using tactical licensing changes against bromite". What a stupid argument. Anyone who spreads such garbage on the internet can't be taken seriously. The chat log also shows the GrapheneOS main dev (strcat) saying:
But the exact same post on that troll website claims that GrapheneOS is "discouraging cooperation between developers". I think I gave more than enough examples why this shit can't be taken seriously. It also shows really well how hostile some parts of the community are against GrapheneOS, for no real reason and with absolutely no arguments.
Another example of this is Jonah Aragon, who posted a really stupid toot on Mastodon, comparing the GPLv2 license of GrapheneOS to FUTO's source-available license. This claim is so infinitely stupid, and by Jonah's definition, the Linux kernel isn't FOSS since it's also licensed under the GPLv2. These are the kinds of people that Graphene devs have to deal with all the time. A bunch of trolls and absolute morons.
Great writeup, I really appreciate it, especially the point about locking the bootloader and isolation - it's all about the threat model of a user.
It's annoying, frustrating, and most of all, disappointing that we get just noise between these projects, rather than mutual respect with clarification of the differences, and the different use-cases, for them. Instead we get adversarialism because some people think only their way is the right way (such as this post).
I run Lineage on a couple devices that can't get any thing else. Some people on the Graphene side would (and have) chastised me for running an "insecure" rom. Well, I know my risks, and the value I get from this device, and I mitigate my risks through layered security (as all risks are) - I'm addressing my threat model.
The issue with the Graphene team is they have the stereotypical, arrogant, condescending attitude of tech people.
I've been that tech person at one time in my career, and got it trained out of me by good leadership decades ago.
The crap they've said, to me (not something I heard second hand), while asking for help was such a major turn off (and in my help desk career would've had them in for re-training), that I gave up on using Graphene. Their attitude was looking for ways to blame me instead of trying to determine why things were misbehaving.
What if I had a true, difficult issue later, this is what I'd have to deal with? I had dismissed the reports I'd read about the team, until I experienced it first hand.
So no thanks. Graphene is dead to me now...I will never... Let me repeat that NEVER use or recommend the system to anyone, unless the team changes. And that's a damn shame, because I really wanted to use it on my phones going forward, and even bought Pixels specifically to use Graphene.
Hey, let me preface this by saying I'm not here to invalidate your experience. I'd just like to understand what happened so, if you want, feel free to shoot me a dm anytime.
For those who say Lineage OS is insecure please tell me how you are able to bypass the AOSP security model.
Funny the downvotes, and yet none of those downvoters cared to explain how it's insecure. So we can ignore them.
Insecure is an absolute term, implying that security is on/off. So we can ignore anyone saying "Lineage is insecure" as it's meaningless.
Nothing is secure. Everything has risks. The key is to manage those risks, and mitigate them as you can for your own threat model.
Part of the Graphene team issue is their ideological approach to security, notably around relocking the bootloader, acting as if Graphene is the only rom that can do this. I can relock my Pixel running Lineage...
Obviously. But relativizing everything doesn't help whatsoever with understanding the true risks associated with specific insecurities. You can read more about the issues with LineageOS at https://madaidans-insecurities.github.io/android.html#lineageos
Just a side note but keep in mind the Lineage OS recovery does allow flashing from either adb or SD card.
Great writeup, thank you for taking the time to be so indepth and helpful
