GrapheneOS does not create identifiers for users nor track them. All services we do host require the minimum for that service to function, for example when requesting an OS update we would only be able to see an IP address checking an update for a certain phone model.
Android has an "Advertising ID" but this is Play Services dependent and can be deleted in their settings.

The Owner user currently must be unlocked at startup first because that profile has critical OS functionalities running there. Sorry about that.
I would follow the same advices in the comments about how to get it serviced without needing them to unlock the device.

An Android 17 release of #GrapheneOS is now available in the Alpha channel for users who do not want to use an experimental channel. This is a major release with some more slight UI changes and an introduction of a Desktop Mode that can be enabled by plugging in a device to an external display via USB-C DisplayPort Alt Mode on Pixel 8 and later. We are regularly working on more fixes in the mean time and it is likely a later release will end up in Stable as there are more releases ready to come now.

2026-06-16 23:45:48 CEST

Today is the official release day for Android 17. We've already fully ported #GrapheneOS to Android 17 and are in the process of pushing the code to our public repositories. We're building a final official release based on Android 16 QPR2 today and we'll do an initial Android 17 release tomorrow.
We've already tested the Android 17 port of GrapheneOS on the Pixel 6a, 7, 7a, 8, 10a, 10 and 10 Pro Fold. It will be possible for people to start building and testing it themselves later today once we finish pushing the code. We'll start the process of public testing for official releases tomorrow.

2. It's a Google / AOSP issue they deliberately hold back patches to critical / high vulnerabilities for over a month. It's also an issue of the OEMs who have these early access but don't issue all the patches. GrapheneOS Security Preview does.

2026-06-07 11:06:54 CEST

- reply

OEMs get early access to the patches and are allowed to push them on their OS, but no one does them all. Google and Samsung do a small amount of them. Since they are embargoed and not open source immediately, they aren't released into AOSP until months later with their scheduled security patch level.

Molly (hardened Signal client) is building a Signal server software called Flatline. This will allow creating Signal deployments with servers that aren't Signal's. They'll also be working on features such as supporting accounts without phone numbers.

The big issue that the post is trying to address is that AOSP and therefore derivatives like LineageOS are also missing these patches for up to 6 months. When OEMs get security preview patches, they may only push ~10% of them earlier than their assigned date too. When switching you could be *less* patched, and it is the upstream's fault.
GrapheneOS on the security preview channel is the ONLY Android distribution delivering all available patches on a regular basis. Despite the embargo preventing releasing the sources, it is easy to use reverse engineering tools to compare differences between standard and security preview builds to find the vulnerability AND the embargo doesn't protect against a resourceful threat actor somehow getting that access.

2026-06-02 20:28:14 CEST

June 2026 Android Security Bulletin notes CVE-2025-48595 is being exploited in the wild. It's being widely misreported in tech media as a 0-day vulnerability being exploited. That's a major misunderstanding of Android Security Bulletins and how poorly OEMs keep up with patches.
Google disclosed CVE-2025-48595 to OEMs in a security preview release near the end of September 2025. Those patches are allowed to be shipped right away, so it was included in our 2025092501 release. We noted it was already publicly fixed so it was added to our regular releases too in 2025100300.
We quickly shipped the patch after it was disclosed to OEMs by Google but we plan to do better in the future. SQLite 3.44.5 was released with this backport on 2025-07-24. We weren't previously aware SQLite maintained upstream LTS branches for Android but our plan is to closely follow those now.
In this case, Google slipped up and took 2 months to add the patch to the security preview releases. We plan to avoid that in the future by handling this ourselves because this happens too often. It's also a nice example of how Android Security Bulletins are set extremely low expectations for OEMs.
#GrapheneOS quickly ships all security preview patches. Every AOSP patch included in the Android Security Bulletins was already available in GrapheneOS for over a month. We end up shipping patches 2-3 months earlier. Google having such low expectations for OEMs and even themselves is ridiculous.
Android's security patch system doesn't make any sense and is completely at odds with how quickly people can discover and exploit vulnerabilities with the help of LLMs. The security preview release system would be far more reasonable if the embargo for sources and details was no more than 48 hours.
Google's embargo system harms security for nearly all Android users by setting the expectation of patches taking 2 to 6 months for OEMs to ship after disclosure. Patches are available to sophisticated attackers as soon as Google discloses them to OEMs. A partial embargo for months makes no sense.

Yep. But Telegram storing all of your group chat messages and having no end to end encryption by default is expected behavior, not your actions also being sent to some random C2 server from an unknown individual. Even nonprivate instant messengers wouldn't dare stoop so low!

A managed service doesn't equal a private or secure service and it isn't trying to say that it is. The post is saying average users (normies) will often use a managed service over running their own even if the service has problems. You could put any cloud storage in that scenario.

There isn't a formal document on our roadmap beyond far future wishes in our FAQ but currently we're working on:
- Replacing Gallery (we're on the last steps for this)
- Overhauling SMS app (got a ton of progress for porting UI to Material 3 Compose/Kotlin but not done)
- To overhaul the contacts app and other apps
- Preparing for Android 17, which moves Desktop Mode to a production feature
A lot of accessibility stuff as well, such a improving the TTS engine, possibly SST. A lot of the work this year is to make GrapheneOS more usable and modern to prepare for the flood of Motorola users by next year.
Improving profiles is a minor feature we want to add later. The second suggestion wouldn't really be possible to meet it's goals as secondary users can't enable ADB for forensics tools that police use. You can't hide the fact you have multiple users at this time. Even the lock screen tells you.

We don't distribute on F-Droid, but this can be used in other operating systems. Best bet is to get the GrapheneOS App Store app so you can get automatic, verified updates for it.

The hardware acceleration works fine on GrapheneOS though, GrapheneOS just doesn't include any AI assistant/generative AI. The project just agrees that should just be left to the user. People will also just be unhappy about it even if it is totally local.

We haven't looked into any LLM / generative AI / agentic AI in GrapheneOS since it's not a field of ours and we try and keep the services minimal. Also it would be pretty limited in coverage if it it's own API had to be made for it because then it deviates from being an Android app.
Latest work on ML is pushing our own Text to Speech engine very soon for accessibility, entirely local, open machine learning models AND training data. Users should be excited for that.
For people into running some local LLMs, the open source and local Google AI Edge Gallery app I showed you before got a lot of changes actually. Does more than just text chat now. Someone could use it or even build a fork with it's permissive licensing.

Because it's one of the only
production wallets with full send/receive, I just set up a Cake Wallet for that. The other two I know of are so new or considered Alpha software so it's more about which is least worst. I don't think you can properly decide at this point, which is why I commented more wallets should be introducing it and then it can be better decided.
If you wanted PayNyms you are also stuck on using Sparrow or Ashigaru and the latter has barely been updated.
Once Sparrow Wallet supports SP fully, I will set up my own way with that since it should also support external signers with BIP375/376. Possibly able to accept them for GrapheneOS donations like we had for PayNyms.

Unified Attestation is another anti-competitive system being pushed by multiple European companies. It will similarly lock people out from using arbitrary hardware and software. That's not a solution and is far worse than Android's much more open hardware attestation API.
https://x.com/GrapheneOS/status/2033925685568250119
Android's hardware attestation shouldn't be used to lock out users not using specific hardware or OSes. However, the fact that it permits arbitrary roots of trust and OSes at least allows services to permit more. Google could use it to permit GrapheneOS for Play Integrity if that was about security.

2026-05-10 18:04:37 CEST

Apple and Google are gradually expanding their use of hardware-based attestation. They're convincing a growing number of services to adopt it. Google's Play Integrity API and Apple's App Attest API are very similar. Apple brought it to the web via Privacy Pass, which Google intends on doing too.
Google's Play Integrity API requires hardware attestation for the strong integrity level and is gradually phasing in requiring it for the more commonly used device integrity level. Apple already has it as a requirement. Over the long term, this will increasingly lock out hardware and OS competition.
The purpose of these systems is disallowing people from using hardware and software not approved by Apple or Google. This is wrongly presented as being a security feature. Banks and government services are the main ones adopting it but Apple and Google are encouraging every service to use it.
Apple's Privacy Pass brought hardware attestation to the web to help with passing captchas on their own hardware. Many people saw that as harmless since few sites would be willing to lock out non-Apple-hardware users. Apple and Google are both likely to bring broader hardware attestation to the web.
Google's reCAPTCHA is planning an approach where they use Privacy Pass on Apple hardware, their own approach on Google Mobile Services Android devices and a QR code scanning system to require an iOS or Google certified Android device for Windows and other systems:
https://support.google.com/recaptcha/answer/16609652
Banking and government services increasingly require using a mobile app where they can use attestation to force using an Apple or Google approved device and OS. Apple's privacy pass, Google's 'cancelled' Web Environment Integrity and now reCAPTCHA Mobile Verification are bringing this to the web.
Current media coverage for reCAPTCHA Mobile Verification misunderstands it and the impact of it. They're bringing a hardware attestation requirement to Windows, desktop Linux, OpenBSD, etc. by requiring a QR scan from a certified smartphone to pass reCAPTCHA in some cases. They could expand it more.
Control over reCAPTCHA puts Google in a position where they can require having either iOS or a certified Android device to use an enormous amount of the web. Google defines certification requirements for Android which includes forcing bundling Google Chrome, etc. It's enormously anti-competitive.
Google's Play Integrity API bans using GrapheneOS despite it being far more secure than anything they permit. It also bans using any other alternative. This isn't somehow specific to an AOSP-based OS. You can't avoid this by using a mobile OS based on Linux or FreeBSD instead. You'll just be more locked out.
Google's Play Integrity API permits devices with no security patches for 10 years. The device integrity level can be bypassed via spoofing but they can detect it quite well and block it once it starts being done at scale. The strong integrity level requires leaked keys from TEEs/SEs to bypass it.
It doesn't provide a useful security feature, but it does lock out competition very well. Services requiring Apple App Attest or Google Play Integrity are primarily helping to lock in Apple and Google having a duopoly for mobile devices. Play Integrity is more relevant due to AOSP being open source.
Governments are increasingly mandating using Apple's App Attest and Google's Play Integrity for not only their own services but also commercial services. The EU is leading the charge of making these requirements for digital payments, ID, age verification, etc. Many EU government apps require them.
Instead of governments stopping Apple and Google from engaging in egregiously anti-competitive behavior, they're directly participating in locking out competition via their own services. Requiring people to have an Apple device or Google-certified Android device is anti-competition, not security.
reCAPTCHA Mobile Verification will currently work with sandboxed Google Play on GrapheneOS but it clearly exists to provide a way for them to start using hardware attestation on systems without it. People without an iOS or Android device will be locked out when this is required even without that.
This isn't about security or any missing functionality. GrapheneOS can be verified via hardware attestation. Google bans using GrapheneOS for Play Integrity because we don't license Google Mobile Services and conform to anti-competitive rules already found to be illegal in South Korea and elsewhere.

This week, we patched a VPN leak in Android that was reported to Google but was ignored. Here is some coverage about that:
https://cyberinsider.com/grapheneos-fixes-android-vpn-leak-google-refused-to-patch
Here is the original vulnerability report:
https://lowlevel.fun/posts/tiny-udp-cannon-android-vpn-bypass/

2026-05-08 08:30:38 CEST

GrapheneOS isn't vulnerable to the 3 recently disclosed Linux kernel vulnerabilities named Copy Fail, Copy Fail 2 and Dirty Frag. Current Android Open Source Project SELinux policies block exploiting all 3 bugs. Standard AOSP GKI kernel configuration also has 2/3 of the vulnerable features disabled.
Attack surface reduction via fine-grained SELinux policy rules and stripping out unused kernel features via kernel configuration goes a long way to protecting against vulnerabilities. There's also seccomp-bpf for various standard sandboxes but most of the attack surface reduction is via SELinux.
AOSP uses SELinux to allowlist ioctl commands for drivers, permitted socket types, etc. in a fine-grained way. It strictly controls a lot of functionality prone to vulnerabilities including user namespaces and io_uring which aren't allowed to be used by apps or nearly any of the base OS processes.
These kinds of issues are rare and attack surface reduction is the best way to defend against them. #GrapheneOS does additional kernel attack surface reduction but in these 3 cases it's enough to have modern AOSP GKI kernel and SELinux policies. We also greatly improve generic exploit protections.
Local privilege escalation vulnerabilities in the Linux kernel are very common. However, the vast majority are memory corruption bugs rather than these memory-related logic errors. We defend against the memory corruption bugs with hardware memory tagging, zero-on-free and similar generic defenses.
Linux has a massive amount of code for the core kernel and drivers for the hardware. All of the code runs with full privileges with no isolation. In a microkernel, each of these 3 recent vulnerabilities would have been in isolated processes. Virtualization will have a major role in addressing this.
Despite these not being traditional memory corruption, a memory safe language with a better type system would definitely help. Containing low-level handling of memory to a much smaller portion of the kernel and mostly using safe abstractions for networking, device drivers, etc. would help a lot.
Linux has a relentless flood of severe memory corruption bugs being discovered. Nearly all exploit chains for Linux-based systems by commercial and government exploit developers use Linux kernel memory corruption bugs. It's a lot harder to make very portable and reliable exploits for those bugs.
A lot can be done to further reduce Linux kernel attack surface in GrapheneOS and much better generic memory corruption exploit protections can also be developed. However, it clearly needs to be replaced. Hardware-based virtualization on smartphones keeps getting better and has a major role to play.

We are releasing an update today to fix this leak.

The #GrapheneOS Gallery app is going to be replaced with a fork of ReFra. Here is how the app looks. It is far more complete and full of features than the original AOSP Gallery. I am sure you will like it.

Reading the post, it looks like this leak was reported upstream into AOSP and was just ignored by them outright. What a mess.
We'll look into producing a fix for this ourselves and forward to the right people since they won't. If the researchers themselves also sent these things to us we could work on fixing them sooner.
Fortunately a native app needs to go out of their way to be designed to do this and certainly no app beyond this PoC is doing it right now.

GrapheneOS doesn't persistently store notifications unless users explicitly enable notification history. For users enabling notification history, it's a 24 hour log that's cleared as soon as the feature is disabled again. This is the standard Android Open Source Project approach.

Privacy and security on computing devices need to become far stronger to protect people from pervasive violations of their rights. Users have their privacy pervasively violated by corporations, criminals and governments. There are endless privacy and security weaknesses in software with exploits of those happening on a large scale. Operating systems, browsers and other apps need to do a much better job protecting users. Enormous progress is needed on both privacy and security.
#GrapheneOS provides a massive upgrade for privacy and security over the standard Android Open Source Project. GrapheneOS is nowhere near good enough and we have an enormous amount of work to do improving both. Our work is an ongoing process and doesn't have an end point. Privacy and security heavily involve competition between attackers and defenders. Most defenders are making little progress and falling increasingly far behind.
Attackers continue improving their exploits of privacy and security weaknesses. Commercial exploit tools are increasingly widely deployed for broad attacks. Software has a very high density of privacy and security vulnerabilities. LLMs are accelerating both vulnerability discovery and exploit development. For most computing devices, defense is increasingly far behind offense. iOS and GrapheneOS are exceptional cases not representative of degrading privacy and security across computing devices.
Growing numbers of internet connected devices are incorporated into botnets. This harms the privacy and security of the internet as a whole through heavily pushing it towards centralization behind services such as Cloudflare. Insecure devices without security patches harm the internet as a whole. It isn't only embedded devices but also desktops, mobile devices and servers being used as part of these botnets. It isn't only people with these insecure devices who are harmed. It can get much worse.
We're building GrapheneOS to protect everyone's privacy and security. It's aimed at widespread adoption and is highly usable. It's compatible with the vast majority of Android apps. It has major privacy benefits for every user including stopping a lot of data collection by apps and services with a better permission model increasingly addressing being coerced to grant access. GrapheneOS has many users with little technical knowledge and isn't hard to install or use.
We're continuing to work on improving privacy, security, usability and app compatibility for all of our users. Contact Scopes, Storage Scopes, per-app Sensors toggle, VPN leak protection and many other features we provde are very important privacy protections. We're building alternatives to the Camera, Microphone and other permissions too. Our major improvements to exploit protections are there to protect user privacy. Privacy depends on security and that's why we heavily work on security too.
Contrary to what's often claimed, GrapheneOS is far more usable and requires far less sacrifice compared to other alternatives. Providing far better protection against sophisticated exploits isn't at the expense of that. Our opt-in sandboxed Google Play compatibility layer combines privacy and high usability. We're gradually making replacements for more Google services apps rely on. Location services, network-based location, geocoding and more has already been replaced and much more is coming.

As far as I know it's not released there. Additionally not every app on F-Droid is reproducible. For the most part F-Droid are simply compiling apps from source and signing it with their own keys.

Use the Telegram official app if you use Telegram. You're using Telegram anyway. There's not really a "hardened" alternative I recommend like Molly for Signal.

(updated post) The Nekogram telegram client contains code that grabs your Telegram ID and phone number to send to their own bots, also some other OSINT bots mentioned. They admitted to it in their channel (@NekoUpdates) and are insulting users in the comments. Assume your number and user can be correlated at a worst case. Keep away from third party clients.

We are an AOSP distribution because of all the security properties it already comes with like the mandatory sandboxing of apps, permission controls, file-based disk encryption, verified boot and more. It compliments what we want out of GrapheneOS. It's an entirely reproducible free and open source project. We don't want to make an operating system using the traditional desktop Linux OS stack which sets us back on all of these things.
There's a lot of things we are against when it comes to big companies like Google but we aren't forcing people to see black and white. A lot of things of AOSP and Pixels we like, but we don't want Google to be the only company producing those things either. We don't call ourselves a degoogling project because people can use what they want on GrapheneOS. Influencing you to create an opposition is politician behavior.

Those are for project account pages. There is no project page for GrapheneOS. I'm just one guy.

The official microG OS project (https://lineage.microg.org) leaked their private keys for logging into their servers and signing releases:
https://github.com/lineageos4microg/l4m-wiki/wiki/December-2025-security-issues
We make our official builds on local machines. Our signing machine's keys aren't ever on any storage unencrypted.
Our roadmap for improving security of verifying updates is based on taking advantage of the reproducible builds. We plan to have multiple official build locations and a configurable signoff verification system in the update clients also usable with third party signoff providers.
We don't have faith in any available commercial HSM products being more secure than keeping keys encrypted at rest on the primary local build machine. Instead, we're planning to develop software for using the secure element on #GrapheneOS phones as an HSM for signing our releases.

No future devices based on current ones looking at as targets appear to be that small. Closest is the Motorola Signature which is 6.8, assuming the next gen successor is the same size as the Signature. The razr ultra is a little slimmer but 7 inches, but folds.

The device / OS pair is certified. It has some requirements that if the OEM follows them they are able to be certified. For example, Google services available, many as privileged components. While we have sandboxed Google Play that is still not sufficient. Some users don't have a play services implementation at all.
So while some OEMs make awfully changed Android releases, ours is left in the dirt there. We don't try for Google certifications.

Imagine it is too late. Will be using the Qualcomm SOC secure element. OpenTitan also isn't built for Android (Titan M2 is based off of this), so there would have to be someone willing to manufacture secure elements and support the Android APIs, etc.

I'm far from a bitcoiner... Strongly dislike maxi groupthink. That post is about funds being moved out of bitcoin and into monero. My following list is mostly devs or xmr. Not sure how praising an availability of a service to offload received funds into xmr is giving up ideals... unless the ideal was being bitcoin only or something? I think people can use what they want.
A ton of privacy features for on-chain bitcoin like Silent Payments are just under adopted (most are just users of one wallet that is on a smartphone) that recieving LN and ramping out into Monero is a much more likely outcome. You're likely to get an LN or XMR address to send/receive to a merchant than a SP address today. Hope it changes.
Nostr users are there because it is almost entirely centred around Lightning. The best clients for it are too. Monero oriented clients are often weird forks or too new to recommend anywhere for my taste. I'm pretty strict on keeping away from software that is new or experimental.
I do want to see improvements on more wallets adopting SPs (big fan of Sparrow) and Nostr clients outside of bitcoinery though

Obviously they'd avoid using a different currency to transact as much as possible.

2026-03-05 09:05:06 CET

- reply

This comment, but I'm mostly talking about recieving funds online. A monero user wouldn't store any funds in Lightning, they simply swap what they recieve into Monero or swap out to make a transaction immediately.
If I had problems with swap services or Spark knowing too much I'd roll funds out to other wallets. This is including both the LN or XMR side. For a long time I off-ramped zaps into other LN wallets or swapped them already.

2026-03-04 22:30:26 CET

- reply

It gets people to gateway into Monero far easier. A lot of concepts people are familiar with in cryptocurrency spaces do not exist or matter in Monero either due to a different climate or technical differences.
You definitely have to be a more technically inclined and aware person to use XMR (this can also be considered a merit) so I think having swaps to/from assets with greater mini economies greatly decreases the entry barrier.

2026-03-04 22:26:41 CET

- reply

XMR can be difficult to receive for new users. Having a lightning address to receive funds that can be swapped is significant. Lightning is very popular amongst smaller purchases and online stores. I buy a fair amount of living resources using ZEUS.
I mention Nostr specifically since Nostr is almost entirely oriented around Lightning. Nostr clients oriented around other assets are often lesser maintained and more risky. These clients are a security haunted houses to begin with. Better to have some sort of LN address to receive and then swap for people into that imo.

2026-03-04 22:19:41 CET

- reply

Yes. Swapping opening up access to a lot of vendors in both teams to make private purchases with one another.
Especially helpful at this current moment since on-chain BTC privacy features like Silent Payments are seldom adopted except for Cake Wallet and partially in Sparrow Wallet. SP to XMR swap far less likely to be than XMR/LNBTC as of right now.

2026-03-04 21:36:08 CET

Lightning support in Cake Wallet should be huge for XMR nostr users

There's nothing to mitigate in the first place. It has nothing to do with GrapheneOS or smartphones. Every Windows laptop vendor has bundled sketchy bloatware in the past and many still do in the present. Security research targets are encouraged, feel free to find something, anything, in these devices that you think are off. Use a non-Motorola device if you want to choose based on pure vibes or you don't like them for any other reason. If you're an OEM, contact us and work with us.
If you really have to get to the details then Superfish is not installed by the firmware but was bundled operating system software and was trivially discovered. Obviously, there's no such thing that will happen here or GrapheneOS, it would be caught by our (very) vigilant users and I know I put the rep on the line saying that.
>now these assholes control the bootloader, the baseband
The bootloader is a standard littlekernel-based Android bootloader. The baseband is Qualcomm's, part of their SoC. Our device requirements on the site state explicitly radios must be isolated and that sensitive data cannot be accessed at the bootloader (working verified boot, zeroing memory left over from the OS, etc.), we are very conscious about that and received bounties for discovering and patching security deficiencies in bootloaders targeting Pixels that were exploited in the wild.
We'll be having involvement in the driver and firmware side of things. Working to improve their security posture and harden their stock OS and firmware is part of the partnership.

What we need more than funding is development resources really. It would be nice to make major improvements to GrapheneOS before devices come out, especially the usability front so we have an even better experience for the tons of new users who would arrive.

As a non-profit we do not take funding with strings attached.
We advise Motorola on what they need for their next devices and in return we can get a device supporting GrapheneOS. We'll be working to also provide lower level hardening for them. They'll also work to introduce some features to their stock OS. We are using partnership to get help with their partner access to see sources to better prepare ourselves for porting to major versions.
We will be working on GrapheneOS for Motorola and it will be the exact same as Pixels in that regard, we distribute updates, etc.
