I can't believe I am still seeing this be suggested as advice in some places, but, no, Signal does not contaminate digital evidence / attack forensics machines. Do not use apps claiming they can make attacks for these tools.
For some background: In April 2021, Signal got a hold of a Cellebrite UFED kit, a software package designed to create forensic clones of data for smartphones. Signal found a remote code execution vulnerability in UFED and made a snarky joke about leaving files designed to exploit the vulnerability on phones with Signal installed that were designed to exploit the vulnerability.
They didn't actually do this, it was a joke, and it wouldn't work. Cellebrite is a multimillion security company, they have the budget and skills to patch.
DO NOT ALLOW YOUR DEVICE TO BE ACCESSED JUST BECAUSE YOU THINK SOME APP WILL STOP IT.
- Cellebrite patched the vulnerability.
- Other retailers like MSAB support Signal in their products, so even if there was an RCE in one tool, another tool would be used instead.
- Giving away your password just because you think the evidence would be tampered is silly. They still have access to your device.
Some other apps you shouldnt rely on are apps that do duress features like Wasted or concept anti-forensic tool apps like LockUp.
For duress apps relying on a device admin like Wasted, the stock OS factory resets on almost any other device that are caused by admin apps can be bypassed by holding the volume down button to fastboot or recovery, effectively cancelling it. GrapheneOS Foundation is on the CVE for this. GrapheneOS duress erases before reboot so you cannot do this bypass.
Remote erasure apps also don't work if you're concerned about users with tools like this. It is common forensics practice to immediately airgap devices with a faraday bag, removing SIM and enabling airplane mode (where possible) to prevent this situation.
Apps like LockUp triggering resets based on detecting tool activity, file hashes and signatures are a temporary, flawed solution
- The companies routinely research these apps and will just change known hashes or signatures if they are found out.
- It uses device admin, so can be bypassed the same way as Wasted.
- LockUp was designed by a security researcher to assist Cellebrite and patch vulnerabilities. It's not been updated in years. Cellebrite gives credit in their changelogs for the disclosure to the authors.
LockUp gets recommended in some space as an app to protect you, but you shouldn't use it. Not even the developer says you should because it's a proof of concept for a vulnerability disclosure.
#GrapheneOS based on Android 15 will reach the Stable channel later today. It's very stable already and we've fixed a bunch of upstream bugs including several impacting the stock Pixel OS. We've made 7 official releases based on 15 already and the 8th is going to reach Stable.
We normally would have had it in the Stable channel already. We've been quickly fixing all the significant issues as they've been reported, but people kept reporting new ones afterwards and they've been past what we consider significant enough to delay the release until today.
An AOSP keyboard app layout issue was reported today where in landscape mode the right side is slightly cut off but still remains usable. We could push out the current release to Stable, but we've resolved this and we're building another release so we'll very likely wait for it.
We're capable of pushing out a fix for the keyboard app issue via our App Store. We're currently considering which option is best while we build the release. It's too bad this didn't simply get reported yesterday in which case the release would already be in the Stable channel.
Our criticism of recently published
Wired article: "Wired's Attack on Privacy"
https://simplex.chat/blog/20241016-wired-attack-on-privacy.html
The need for cyber security existed entirely out of a need to prevent people being a victim of cyber crime.
People being tech-literate and using the best technologies available to them is standard to a connected society. This can't be prevented and no developer ever deserves to be blamed for what is outside of their own control.
Cyber security is non-negotiable and making compromises enables criminals more than anything else because criminals prey on the weak, the vulnerable, the easy targets. Making a spin on tools that empower the vulnerable as tools to enable criminals is nothing short of slanderous to the projects and the good people protected by these works.

I've not posted changelogs for today's update as there will be more updates for Android 15 fixes as they come including another update today/tomorrow. Would spam the feed.
Most users will not get the Android 15 updates yet as it is exclusive to Alpha release channel so testers can provide feedback on fixes with AOSP bugs.
Some improvements also need to be made to Private Space. It needs to be worked on further to be more useable to GrapheneOS users, like an install available apps feature similar to user profiles. Private Space was only designed for installing apps from the OS source so it ends up opening the GrapheneOS App Store or Play Store for now, would need to get APKs manually, may be a problem to some.
Private Space also can't transfer files from Owner to Private Space (other way around is fine) which is a regression. Additional work needs to be done.
Here is how the Private Space feature looks so far. This footage belongs to tuxsudo, a Cake Wallet contributor.
Check out his thread for more, note this is footage from a sideload-only pre-Alpha build of GrapheneOS and regressions in this thread have or are currently being addressed in following updates. If you are a normal user then you do not have this feature yet.
Not usually something I like to post about, but I was waiting for a Material 3 UI Notes App for a long time.
Then I found this app: 
Text formatting, exports to Markdown and JSON, media support, and encrypted backups. I've personally wanted an app like this for a long time. Other apps are either text editors or are very dated.
Apps like these fit extremely well into #GrapheneOS and I have a soft spot for them. I hope the developer continues working on it.

6 Pro was the first phone to get the 120hz display. But the 8a is the first A-series to get 120hz. The 6 Pro is cheaper, but the 8a is better value with an extremely long update span and the best security features.
There isn't a formal vetting process as we rarely make app recommendations. Accrescent is maintained by a long-term community member and we have been indirectly watching progress over it since the project started since we needed something like it. If we had the resources we'd be funding it ourselves.
Our initial #GrapheneOS release based on Android 15 is now available for early testing for technical users willing to sideload the release to their device. It's a regular production release and this can be done on a locked device with USB debugging disabled, but it's not heavily tested yet.

#GrapheneOS version 2024101600 released:
This is the initial release of GrapheneOS based on Android 15 based on the October 15th stable release of Android 15. We had previously ported all of our features to Android 15 based on the Beta releases and have been finishing it up based on the early September release of the source code for Android 15.
The most notworthy addition to GrapheneOS from Android 15 is Private Space, where users can create an isolated, sandboxed environment on their device to separate apps. Apps in the private space show up separately to other apps and are hidden from the recents view, notifications, settings, and from other apps when the private space is locked.
The sandboxed space works like a profile where the end user adds or installs an app inside private space and the app is installed in a new Android profile. The system treats this as a fresh app install, and no app data is copied over to the private space. When the space is locked, the private profile user is stopped, and when the space is unlocked, the user is started.
Apps in the private space are installed as separate copies of the apps in the main space. User content (user-generated or downloaded) and user accounts are separated between the private space and the main space. You can use the system Sharesheet and the Photo Picker to give apps access to content across spaces only when the private space is unlocked.
A private space does not replace user profiles, although it may be better for some users depending on what they use user profiles for. Currently, private spaces are only able to be ran on the Owner profile. We hope to add improvements and enhancements to this feature, in theory there could be support for multiple Private Spaces at once but memory usage is a concern and this needs to be considered first.
Changes since previous version:
- full 2024-10-05 security patch level since the Pixel patches were disclosed in the Pixel Update Bulletin today rebased onto AP3A.241005.015 Android Open Source Project release (Android 15)
- full port of GrapheneOS features to Android 15 including integration of our features with the new Android 15 features including Private Space
- Sandboxed Google Play compatibility layer: add stubs to fully remove the need for the Google Services Frameworks app, which has been removed as a dependency in our app repository for Android 15+ and you can remove it for an existing install of sandboxed Google Play after each Google Play services installation runs at least once on Android 15 which migrates the GSF databases to itself (stock OS still requires this despite nearly fully obsoleting it for Android 15)
- Pixel 9 Pro Fold: add assorted device-specific Settings and SystemUI changes to better match the stock OS
- kernel (6.6): update to latest GKI LTS branch revision including update to 6.6.56
- Vanadium: update to version 130.0.6723.58.0
- GmsCompatConfig: update to version 141
This update is currently limited to a sideload-only release but if there are no regressions it will be pushed into the over-air updates. For users on Stable, expect Android 15 releases to come to your device in the coming days.

Initial Android 15 release for GrapheneOS looking good so far. OS builds are built for 6/15 devices and counting. Hope to have a release out soon.
Big day for GrapheneOS coming.
Cellebrite recently had a job application for an Android security researcher with experience in MTE and PAC (ARMv9 security features) as a desirable bonus.
Can you guess the only mobile OS with the best/only production MTE implementation and PAC in userspace and not just kernel?
🫣🤔
If you mean state-level threats, it's not likely they'd want to target the secure element unless there's a requirement to prove they aren't tampering with data in the operation. This capability is most useful for attacks with physical access. Cellebrite wants this because their tools are used with seized phones for customers to extract a forensic copy of it's data.
It is almost certain groups are researching this capability. We recommend users to use a high entropy passphrase that can't be brute forced if they believe that it could happen and if it will be used against them. Brute force also doesn't always mean secure element is exploited, MSAB's now burned stock Pixel brute force capability used a memory dump instead of secure element.
Remote exploitation may be better for intelligence agencies. GrapheneOS defence strategy puts remote exploitation as the most dangerous threat we want to protect against. Users with that risk should do due diligence on who and what apps they communicate with.
CashApp works on my CalyxOS device, but not my GrapheneOS device. nostr:npub1c9d95evcdeatgy6dacats5j5mfw96jcyu79579kg9qm3jtf42xzs07sqfm do you have any input on this? Do you know how to make CashApp work on Graphene? nostr:npub1qny3tkh0acurzla8x3zy4nhrjz5zd8l9sy9jys09umwng00manysew95gx
CashApp isn't available in my country. I'd suggest their web app or using the sandboxed Play Services, or registering an account on another device and logging in on here.
If it doesn't work, it's blocking OSes that are not Google certified
Worth noting it's same with the team. Some have technical knowledge but some don't use them because they have different backgrounds. Some full-time devs are paid with BTC and Monero but not all.
