CalyxOS 4.10.0 - NOT June 2023 Security update is now available for the Pixels, Fairphone 4, and SHIFT6mq

Released to stable on Thursday, 4 May.

This update initially rolled out in our new Security express update channel, which can be summarized in four words: Fastest updates, possible breakage.

The Security express channel

The Security express channel, which first debuted in April, allows us to achieve two major goals:

• Ship AOSP’s security updates faster, for users who want to receive security fixes as quickly as possible, even in the face of possible bugs.
• With your help, catch and fix bugs that appear after merging security updates, before they reach the Stable channel.

Promotion to Beta and Stable

• Most of the time, Beta will get the update in a few hours after Security express. Sometime it may be delayed if there’s major issues, however.
• Builds are bumped to stable after ample feedback from Beta and Security express, usually in a day or two.

Updating via Security express

1. Open the Settings app on the phone
2. Scroll down and tap System, then System update settings
3. Tap Release channel, and select “Security express”
4. You can tap “Check for updates”
5. If it doesn’t do anything, make sure to check the “Permitted networks” setting

Changelog

• CalyxOS 4.9.0 and 4.9.1

Note

CalyxOS 4.8.3 - April 2023 feature update is now available for Pixels, Fairphone 4 and SHIFT6mq

Released to stable on Wednesday, 26 April.

Devices on 4.7.x beta

We released 4.7.6 and 4.7.7 as beta late last month, and included some changes in that which didn’t make it to the previous stable build (4.8.0). We don’t usually do that, where the next build doesn’t include some of the changes made in the previous build.

This build (4.8.3) includes all of those changes, and it’ll continue like that going forward for the most part.

Changelog

• CalyxOS 4.8.3
• April 2023 Feature update

Note

CalyxOS 4.8.0 (and 4.8.1) - April 2023 Security update is now available for Pixels, Fairphone 4, and SHIFT6mq

Released to stable on Friday, 14 April.

This update initially rolled out in our new Security Express update channel, which can be summarized in four words: Fastest updates, possible breakage.

Introducing Security Express

The Security Express channel allows us to achieve two major goals:

• Ship AOSP’s security updates faster, for users who want to receive security fixes as quickly as possible, even in the face of possible bugs.
• With your help, catch and fix more bugs that appear after merging security updates, before they reach the Stable channel.

Differences from Beta

Unlike the Beta channel, Security Express does not include large CalyxOS features or changes that are currently in testing, although updates may include other smaller fixes and improvements. Most of the time, Beta users and Security Express users will receive security updates at the same time; however, CalyxOS feature updates may occasionally require a longer testing period, in which case Security Express users will receive such updates earlier.

Updating via Security Express

Note: This channel selection is reset on reboot, but in the future, we plan for Security Express to be an option in our updater.

1. Make sure your phone is running the latest stable CalyxOS, 4.7.5 at time of writing.
2. Back up your data - you can use SeedVault, the included Backup app. This is optional, but it’s always recommended.
3. Enable USB Debugging on your phone.
4. From your computer: adb shell setprop sys.update.channel security-express
5. Then, on your phone: Settings -> System -> System update settings -> Check for updates

Devices on 4.7.x beta

This month, Beta users will receive the security update a little later so that their devices retain particular features and fixes added in 4.7.6 / 4.7.7 which have not yet reached the Stable channel.

Note

CalyxOS 4.7.5 - Bugfix for March 2023 Quarterly Platform Release and Security update is now available for the Pixels and the Fairphone 4

Released to stable on Friday, 24 March.

Background

Google releases security updates every month, which are usually easy to integrate. However, every 3 months, they also released what’s called a Quarterly Platform Release (QPR).

That’s currently December, March, and June. Then in August / September we have the new Android version. These quarterly updates include a LOT of code changes. They’re also that month’s security update, meaning we have to get it all integrated quickly.

This led to a scenario where the first build of this month had a bunch of bugs that we couldn’t catch before the release, and we didn’t want to delay security updates either so we didn’t wait too long to test out every single thing.

We’re looking into ways to maintain stability while also not delaying security updates. See this GitLab issue for the existing discussion. We’ll post an update once we have something implemented.

Navigation

As noted in the changelog below, 2 button navigation has been dropped. It had a bug after Google’s March 2023 changes, wherein the recents menu (list of running apps) would only show on the homescreen.

Google never included 2 button navigation on devices newer than Pixel 4, and given that those are all no longer supported, this feature doesn’t get tested or fixed by them.

As such, given we had already kept it alive for years longer than Google did, we decided to drop it, because even if we fixed it now (which may have taken a lot of time), it could’ve broken again in the future. We’d much rather spend time on privacy and security related features.

Changelog

• CalyxOS 4.7.5
• Drop 2-button navigation. It will get switched to 3-button navigation automatically.
• Google hasn’t supported this in years, and recent bugs made it unusable.
• Chromium: Fix adblocking, update to 111.0.5563.115 (latest stable)
• Fix scramble pin
• Fix notifications for default SMS app (Messaging)
• Bring back Material You color themes, add more colors to it
• Fix status bar vibrate mode icon
• Improve theme of Settings -> System -> Other options -> Battery stats
• Improve theme of Settings -> System -> Status bar icons

Pixel 6, 6 Pro, 6a:

• Fix Safetynet attestation
• Switch back to source-built kernel

Pixel 3, 3 XL, 3a, 3a XL

• Fix auto brightness

FP4

• Fix auto brightness

Note

CalyxOS 4.7 - March 2023 Quarterly Platform Release and Security update is now available for the Pixels and the Fairphone 4

We test all builds before release, however we cannot test every single thing on every single device, it’d take too much time. That’s why we release the builds to beta first, and then to stable afterwards.

Unfortunately, due to a mistake we accidentally released a buggy update to stable for Pixel 6 Pro. A fixed build has since been made available. Our apologies for the incovenience.

It was bumped to stable on Monday, January 2, 2023.

We’re still investigating the issues reported in 4.4.0, mainly the random shutdowns which seem to be happening for some people.

Changelog

• CalyxOS 4.4.1

Note

CalyxOS 4.4.0 - December 2022 Quarterly Platform Release and Security update is now available for the Pixels 3 - 7, and the Fairphone 4

Changelog

• CalyxOS 4.4.0
• December 2022 Quarterly Platform Release and Security update
• Clock: Fix alarms, remove PHONE permission. Our apologies for the inconvenience.
• Calendar (Etar): Fix crash when creating new event.
• Double tap to sleep is temporarily broken, will be available again in the next update
• Allow Chromium (and many other browsers) to use autofill
• Fix work profile apps occasionally missing in recents for profiles created going forward
• A fix for some of the existing work profiles with the same bug will be avaiable in the next update

Clock app

• In the previous build (4.3.1/4.3.2), we merged some improvements to the AOSP Clock app, which led to it asking for the PHONE permission, and crashing when not given.
• This also resulted in alarms being broken for those who didn’t open the app at all, or opened it and denied the permission. They worked fine for those who opened the app and gave the permission.
• For this build (4.4.0), we have reverted the changes entirely, thus taking away the PHONE permission. This should fix alarms.
• Going forward, we will take further care to make sure that something like this doesn’t happen again. Both the permission, and alarms being broken.

Background

• The AOSP Clock app, like most other AOSP apps, doesn’t really receive any updates.
• LineageOS does a lot of improvements to this app, and thus we’ve been shipping with those to provide a better experience.
• The AOSP Clock app has always had the PHONE permission, however it was restricted to older Android versions.
• A recent update bumped the targetSdk of the Clock app to the latest, Android 13 / API 33. Part of this required making the PHONE permission required again.
• It was used to detect if a call is ongoing during an alarm, and if so, play a different, less loud tone. It wasn’t used for anything else at all. That can be reviewed in it’s removal below.
• If the permission was denied, the app crashed, thus making it unable to play the alarm
• Google’s proprietary Clock app somehow detects phone calls without needing this permission, however we haven’t been able to figure out how just yet.
• Going forward, we’ve decided to simply remove the permission.

Note

CalyxOS 4.3.2 is now available for all supported Pixels, and the Fairphone 4.

Bumped to stable as of Dec 7, 2022.

December update

IMPORTANT

Hello,

Google has released Android 13 to AOSP today, and stock builds for the Pixel 4 and above are now available.

The CalyxOS team is already working on it, we’re going through the source code and will start migrating our changes to 13 soon.

You can follow progress at https://gitlab.com/groups/CalyxOS/-/epics/33 - and we’ll keep posting updates here.

CalyxOS test builds for the OnePlus 8T, 9 and 9 Pro have been shipping with the Android 11 firmware, since at the time the work to update custom ROMs to be based on that was still work in progress for some models, and for others full kernel source code was not available until recently.

However, now that full kernel source code is available, and a big chunk of the work needed is done, we started integrating those changes into the CalyxOS codebase and made some test builds.

Unfortunately, re-locking the bootloader with a custom ROM installed no longer works with the latest Android 12 firmware from OnePlus. :(

What you need to do

• We will be looking at everything and make another post with findings with next steps.

• For now, we’ll make updates with Android 11 firmware since we’ve already released test builds and would like to provide updates with at least the open source parts of the latest security patch and other general CalyxOS improvements.

• We have pulled the links to the existing builds till then while we figure this out.

Technical details

With the Android 12 update, OnePlus changed codebases to be more closely based on Oppo software, and the unification is going to continue.

This meant a lot of changes for custom ROMs all around - to the proprietary files, the kernel code, hardware code (such as fingerprint reader), and also the bootloader.

Sadly, based on our testing, it appears that re-locking the bootloader after installing a custom ROM (aka AVB Yellow state) is no longer working with OnePlus’ Android 12 bootloader (and associated proprietary components).

It is possible that we might be missing some change to make it work with OnePlus’ Android 12 bootloader, but we’ve tried a bunch of things without any luck.

We also tried reverting some components (mainly just the bootloader) to Android 11 while keeping the rest of the proprietary bits matching OnePlus Android 12, but that didn’t help either.

Relocking worked fine with the Android 11 bootloader (and associated proprietary components).

Our options

This means that we will not be able to merge the Android 12 changes into our codebase for now, given that an update with that included would lead to a non-functional device for anyone with a locked bootloader, which would have to be recovered with MsmDownloadTool

All of the possible ways have been listed below, while we evaulate them to decide on the future.

Best case scenario

• OnePlus re-adds this functionality, given that they’ve supported this on pretty much all of their previous devices
• This would mean we can simply make an update with the fix included and it would be entirely seamless.

Future (Android 13)

• We’ll keep trying all options, and keep posting updates here
• With all options there are some pretty significant cons making it hard to pick either

1. Continue with Android 11 bootloader and other proprietary components

Pros:

• Locked bootloader

Cons:

• No security patches to any proprietary components.
• Diverging from other custom ROMs
• Becomes harder and harder to get newer Android versions running

2. Update to Android 12 bootloader and other proprietary components

Pros:

• Security updates
• Same as other custom ROMs

Cons:

• Unlocked bootloader, all the benefits of Verified Boot are lost

3. Get a combination of Android 11 + 12 components working

Pros:

• Locked bootloader (if it works)
• Partial proprietary security updates (the components that are on 12)

Cons:

• Fragile
• Would still miss some security updates (the components that are on 11)

This is the first in a series of regular updates from the CalyxOS team.

It currently covers the things that we’re currently working on, and what we plan to work in the near future.

All of this development can be followed on our Gerrit instance

Known issues

• Work profile creation fails on 3.6.0
  • Fix almost ready for next update, update will be released as soon as this is done
• Chromium crashing when microG is disabled
  • Investigating
• Chromium native autofill
  • Work in progress

Chromium based on Bromite

• Latest stable is 103
  • Work in progress
  • First build will be available shortly in the GitLab testing F-Droid repo
• Will continue looking at bringing over more features
• Reliable updates for Trichrome outside of OS updates work in progress

SeedVault

• Testing a way to allow backing up more apps, see #165 #407
  • We’re hoping to release some test APKs soon to get more feedback and then decided how to best proceed with this

Devices

Pixel 3, 3a

• Microphone low volume fix ready for next update

Fairphone 4

• Working on June update with latest firmware plus other fixes
• Stock Android 12 status still unknown, would be super nice to have it before Android 13

OnePlus 8T

• Working on June update
• Android 12 firmware update is pending

OnePlus 9, 9 Pro

• Working on June update
• Android 12 firmware update is work in progress

Other new devices

• Nothing planned soon as of yet, we’ll keep posting updates

Future planning

• More updates, especially for new features / bugfixes
• AOSP Security updates are already merged monthly
• Setting up a schedule for various merges (Translation, LineageOS, other apps, etc) to make sure they’re always done in a timely manner rather than the current ad-hoc on demand system
• CI (integrated with Gerrit), likely using Jenkins.
• Android 13 rough plans, release is still months out

We’re hoping to make this either a monthly or fortnightly thing. Let us know any suggestions about things you’d like to see specifically, or anything really! You can reach us at Community

We’ve entirely reworked our Chromium fork to be based on Bromite

The stable version for Android, 102.0.5005.98 is now available in our F-Droid repo.

The previous version, 102.0.5005.78 is shipping in the June update, CalyxOS 3.6.0

Background

We’ve been shipping Chromium since day one, since on Android apart from being a full browser, it also provides the WebView (used by more apps than you’d think - changelog in our Updater, DuckDuckGo Browser, many Reddit apps, etc.)

Additionally, we also ship Tor Browser for protection against tracking, surveillance, and censorship.

Bromite has some very useful features, and scores well on privacy tests thanks to their extensive patches. Thus it was decided that we will start to ship a fork of Bromite as our version of Chromium.

We also used to ship DuckDuckGo Browser as the default, but we’ve dropped that in the June update.

• Having multiple browsers is confusing for users.
• With a Bromite fork now, we have built in adblocking.

What you need to do

Nothing!

If you’re already running CalyxOS, then you’ll get this directly with the June update, CalyxOS 3.6.0.

If you’re already using Bromite on CalyxOS - this does not affect that at all, it replaces the Chromium version we shipped.

We don’t plan on making these builds available for normal installation on other ROMs, you can simply install Bromite directly on those.

Features

• Built in AdBlocking, enabled by default.
  • Disable globally from Chromium -> Menu (top right) -> Settings -> AdBlock settings
  • Disable per-site from Chromium -> padblock (top left) -> Permissions -> Ads
  • automatically updated adblock filters
  • customizable adblock filters via user-provided URL (see www.bromite.org/custom-filters)
• Native Android autofill support
• Most if not all of Bromite’s privacy-related features are included.
• Some other features are also included, but not all of them, for now.

Differences

• We try to build everything we ship in the OS ourselves, and it also gets signed with our private keys.
• We’re starting with a smaller set of patches to keep the port manageable on our end.
• Additionally, we build a different variant than upstream to share some code between WebView and the browser given that we’re shipping both at the same time in the OS.
• The idea was that we can always add more later depending on how things go.

Known issues

• Chromium (and other Chromium based browsers) crash on video playback if microG is disabled. Looking into it.
• Enabling native autofill for incognito mode causes a crash, looking into it.

Future

Chromium version updates

Going forward, we will ensure that updates are timely.

As a first step towards this, we started on trying to port to 103 already, and opened a discussion with Bromite on how to proceed for this version and also going forward.

We will try and get the port done around the time the last/fourth beta is released, which is usually a week or so before the same release gets bumped up to stable.

Example: 102.0.5005.58: Beta -> May 19 2022, Stable -> May 24 2022

Delivering those updates to your phone

We’ve had patches in F-Droid to be able to update Chromium outside OS updates, and while for the most part it works, there have always been reports of some people not being able to update. We’ve tried a few fixes so far but nothing has been 100% reliable.

To end that once and for all, we’re testing a patch directly to the OS to allow updating this seamlessly. Hopefully that addresses it going forward.

Links:

• Bromite Website
• Bromite on GitHub
• Our fork on GitLab
• Prebuilt APKs

CalyxOS currently supports 12 Pixels (3 and newer), and we’ve got test builds available for 1 Fairphone and 3 OnePlus devices. That’s a total of 16 devices.

We’re also planning to add support for even more devices in the future, always trying to find more devices to which we can port CalyxOS.

We intend to provide high quality OS releases, where every single build is tested before release. This is not easy to scale, and takes a lot of time and effort. As such, sometimes we have to drop certain devices, especially when they’ve stopped receiving security updates given that we can only do so much.

Previously we’ve supported the Pixel 2, 2 XL and Mi A2. The last update for those was in February 2022.

General

We aim to support devices for as long as feasible, and provide monthly security updates

We will continue providing updates:

1. While we’re on the same Android version.
2. At least until the matching Linux Kernel LTS version is supported.
3. If we manage to port a newer Android version in time, we will continue supporting that device while we’re still maintaing that version for other devices.

Examples

1. Pixel 3 is still getting updates from us (including 12L), Google’s last update was February 2022.
2. Pixel 2 got dropped in February 2022, that’s when Linux 4.4 stopped getting updates.
3. Mi A2, CalyxOS was on Android 11, Xiaomi only provided Android 10 for it.

Device specific

Pixel 2, 2 XL

• Google’s last update was in Dec 2020, Android 11.
• We provided Android 11 builds till February 2022.
• Linux version 4.4 got its last update in February 2022.
• We’re aware of other ROMs making Android 12 available for this device, however the above factors still stand and thus we had to drop this device.

Mi A2

• Xiaomi’s last update was in August 2021, Android 10.
• We provided Android 11 builds till February 2022.
• Linux version 4.4 got its last update in January 2022.
• There were some promising ports of Linux 4.19 to the A2 early 2022, which is why we thought we could provide Android 12. However, upon closer inspection, it was found out that to get this fully working we’d have to use some leaked proprietary files - which we didn’t want.
• We’re aware of other ROMs making Android 12 available for this device, however the above factors still stand and thus we had to drop this device.

Pixel 3, 3 XL

• Google’s last update was in Feb 2022, Android 12

The Dirty Pipe Vulnerability

A vulnerability was found and patched in the Linux kernel.

This build includes the fix for the Dirty Pipe vulnerability.

There are no other changes, compared to 3.2.1

More details: https://dirtypipe.cm4all.com/

Affected devices

This vulnerability only affects Linux kernel version 5.8 and higher.

Pixel 6 and 6 Pro use Linux kernel 5.10, hence they were affected and updated.

All other older Pixels use an older Linux kernel version, hence they are not affected by this vulnerability

Timeline

All times in IST (Indian Standard Time, GMT +5:30), 7 March 2022.

Process

We push the code to Gerrit Code Review. In this case, not many changes, https://review.calyxos.org/q/topic:dirtypipe

The release process is tracked on GitLab - we use checklists to make sure no step is missed.

Also, no matter what, every single build is tested once before release to ensure a stable experience.

12L

We’re aware that Android 12L was just released, and are working on it. It may take some time given that it’s a larger than usual release. We’ll continue posting updates here.

We’ve seen the many reports of push notification delays, and experienced them ourselves as well.

We believe we’ve managed to fix the issue, and a test APK is now available.

You can get it from our test F-Droid repo, https://gitlab.com/CalyxOS/calyx-fdroid-repo

To add it, simply add this URL to F-Droid -> Settings -> Repositories -> Plus sign at the top right: https://calyxos.gitlab.io/calyx-fdroid-repo/fdroid/repo?fingerprint=C44D58B4547DE5096138CB0B34A1CC99DAB3B4274412ED753FCCBFC11DC1B7B6

Alternatively, you can scan the below QR code:

The changes included have all been sent to microG upstream for integration in the codebase so that everyone can benefit.

• https://github.com/microg/GmsCore/pull/1681

We will continue observing push notification behaviour, and update things as needed.

Technical

With all the push notification fixes we’ve done previously, push notifications were indeed working fine - microG was getting the messages on time from Google.

However the way Signal sets up push notifications with Google Cloud Messaging / microG is quite smart - it does not send any data at all through Google, just the fact that there is a notification.

Literally, AppData{key=notification, value=} is what it gets.

On receiving that, Signal contacts their own servers to get the encrypted notification content directly, and then decrypts it on device.

However, Android is very restrictive of what apps can do in the background to improve battery life, and as such that last part wasn’t working. microG does have the code to temporarily allow the app to do what’s needed when it gets a notification, however it wasn’t working on Android 12. The patch fixes that by using a new, different API to perform that on 12, thus preventing notification delays.

Background

One of the most common questions we get is: “Will CalyxOS run on my device?”

When choosing to support a device, we consider the following factors:

• How difficult is it for the latest major release of Android Open Source Project (AOSP) to run on the device?
• How difficult is it to unlock and re-lock the device?
• How long can we support the device?
• How affordable and globally available is the device?

We currently support Google Pixels 3 and above.

Pixel phones are the reference model that AOSP is designed around and Google provides all of the code needed to get AOSP running on the Pixels. This means that although we do make some changes, such as the handling of proprietary files, most of the work is already done by Google.

We also want to support devices for as long as possible. This reduces e-waste and makes CalyxOS more accessible to users who can’t afford to replace their phone every few years. Therefore, we try to pick recently released devices because it takes a long time to get them fully working, and because supporting devices with a full feature set and security updates beome harder, and sometimes impossible, the older they get.

We would like to support more affordable and widely available devices than just the Pixels, which are expensive and only sold in a select few countries.

We supported the Xiaomi Mi A2 because it was an Android One device, which meant that it received timely security updates from it’s release in July 2018 until manufacturer support ended in August 2021.

Planned devices, short term

In the coming months, we intend to support the following devices:

Fairphone 4

• Fairphone graciously sent us a FP4 device to help with development. Thanks for that!
• We have worked in cooperation with other Free and Open Source Android based projects to get this working
• /e/ OS already had Android 11 running on this device, which helped serve as a known good working base to get LineageOS 18.1 running, in collaboration with some other developers already working on porting LineageOS.
• Based on that, we were also able to get LineageOS 19 booting.
• All of the above means that a lot of the work needed to get an open source non-manufacturer ROM running on the device has already been done, and we’re able to utilize that as a base and work on top of that.
• We were able to install our build of CalyxOS 3 - Android 12 and re-lock the bootloader. It’s quite functional too, with only a few minor bugs remaining to be fixed, which we are working on.

OnePlus 8T, 9

• These devices are officially supported by LineageOS, thus basically all of the hard work is already done.
• We experimented with this in late 2021 just before Android 12 was released, however we ran out of time to release a build. We were able to get CalyxOS running, and re-lock the bootloader.
• Now that we’re done with the update to Android 12, we can revisit our OnePlus port.
• We’ll also look into supporting the 9R, 9 Pro, and perhaps 9RT if there’s demand for those.

Other devices

• These are the devices we’re initially focusing on, however they won’t be the only ones we add support for this year!
• We’ll support the new Pixels as they come out of course.
• We also want to support other devices, especially ones that are cheaper and globally available - however we will need to make some other changes for those based on our findings, stay tuned for more updates!

Unlikely to be supported

• We’re often asked about supporting the following OEMs / devices. Unfortunately, we’re unlikely to to be able to for the reasons listed below.

Fairphone 3

• It’s still on Android 10 officially, with old hardware not supported by Qualcomm any longer, and thus too old for us to support since we only support the latest Android release.

Samsung

• Samsung has been really good with updates lately, sometimes release them even before Google does!
• However, as far as we know they do not support re-locking the bootloader.
• In fact, some of their models don’t even let you unlock the bootloader in the first place.
• Additionally, due to all of these factors, there’s not much custom ROM development for these devices in general.
• All of this means we’re unlikely to support any Samsung devices.

Nokia

• Nokia devices mostly run Android One and receive timely monthly security updates.
• Sadly they don’t allow unlocking the bootloader at all on most of their phones which means you can’t install any custom ROMs on them.

Others

• It’s hard to make a blanket statement for all other devices, we will look at more devices in the next few months and post about them here.

Builds

• We plan to release test builds for these new devices as we can.
• You can join our testers channel if you’d like to help test those!

CalyxOS 3.2.1 - February 2022 Security update, take two, Pixel 6 and 6 Pro

Google released an update outside their normal schedule for the Pixel 6 and 6 Pro, containing security fixes from previous months. Due to how CalyxOS code is maintained, most of those security patches were already included in the previous build (3.2.0). This build only contains some minor changes to proprietary files, and translation updates for CalyxOS components.

It is a really tiny update, the incremental zip is only 6.1MB. Click here to see the code changes

CalyxOS 2.14.0 - Android 11, February 2022 Security update is now available for the Pixel 2, 2 XL and Mi A2.

Sadly, we will no longer be able to provide OS updates for the Pixel 2, and Pixel 2 XL. The Xiaomi Mi A2 should get Android 12 at a later date, if everything goes well.

Details

Pixel 2, Pixel 2 XL

This is the final CalyxOS update for these devices. Google stopped updating the Pixel 2 series as of December 2020.

Up till now, we extended these phones useful lifetimes by patching the open source components: AOSP and the Linux kernel. Linux kernel 4.4 was a long-term support kernel, but has stopped receiving updates this month. ( see https://en.wikipedia.org/wiki/Linux_kernel_version_history )

Unfortunately due to the kernel dependency, it is also not feasible to have Android 12 fully working on these devices. There are various community efforts, but there’s no fully working port as far we know.

As such, we have decided to stop updating these devices. Applications such as Chromium and microG will still continue recieving updates.

Xiaomi Mi A2

This will be the final CalyxOS Android 11 build for this device. We’re currently working on getting CalyxOS Android 12 working, so far it looks quite promising. We’ll keep posting updates on our website.

Please note that Xiaomi has stopped providing updates for this devices. We’ve been keeping the open source components updated, and that’s included in this build.

Additionally, the proprietary firmware componets are from September 2020, since trying to upgrade to anything newer ends up factory resetting the device.

Android 12 status

Pixel 2, 2 XL

• We’re aware of various builds of other ROMs available for the Pixel 2.
• However, as far as we know, they aren’t fully working due to missing BPF updates in the Linux kernel, needed for the networking features to work (traffic counting, firewall, etc)
• There is some work being done by other ROMs to port a newer kernel (4.14/4.19) to other devices with the same chipset, which should help.
• We will be looking into this in the coming days and week, and should have more info to post later this month.

Mi A2

• We are aware of some 12.0 builds available for the A2 with Linux kernel 4.19 - that looks very promising!
• We will be looking into it more in the coming days and week, and should have more info to post later this month.

Alternatively, you can scan the below QR code:

The changes included have all been sent to microG upstream for integration in the codebase so that everyone can benefit.

• https://github.com/microg/GmsCore/pull/1483
• https://github.com/microg/GmsCore/pull/1582

This F-Droid repo also includes the GCam Photos Preview app to preview photos directly from Google Camera (without having to install Google Photos)

Note:

We’re in the middle of revamping our F-Droid repository setup, and this will change. In the future, we will be able to push out updates directly to the device without you having to add any custom repos

The October Security update is here. It also contains some bugfixes and minor features that we had been working on.

Google has released Android 12 to AOSP. They are yet to release the Android 12 update for the Pixels though, stating that it’ll be available in the next few weeks.

We have started work on porting CalyxOS to Android 12. We can port the general OS changes we make (microG, work profiles, firewall to name a few) right now, and then wait for Google to release the update for the Pixels before we can start working on having builds ready.

• Pixel 3 and above: Will receive Android 12 update after Google releases it, and we port our changes.
• Pixel 2: Still looking into the feasibility of porting Android 12.
• Mi A2: Same, we’re still looking into it.
• Pixel 6: This will be supported, however it will take a while since it’s an entirely new device, and we’d also need to do the 12 port in general before we’re able to release Pixel 6 builds.
• Other devices: We’re looking into supporting more devices, however for now we’re prioritising the Google-supported Pixels for Android 12.

You can follow the progress on GitLab and Gerrit. We will continue posting more updates as the port progresses.

We’re also working on getting the October 2021 Security update (Android 11) out for all supported devices.

The Pixels have great cameras, and Google Camera works really well on them.

However, with recent versions, Google Photos has been required to view the pictures taken directly from the Camera.

We have created an app to avoid that, called GCam Photos Preview.

It’s a tiny app that you can install in lieu of Google Photos to be able to preview captured images directly from Google Camera

Steps:

1. Uninstall Google Photos (if you have it installed).
2. Download and install GCamPhotosPreview.apk.
3. Open Google Camera, try to view an image by tapping on the bottom right preview circle.
4. If you scroll past the first image, you may be asked to grant storage permissions. That’s required to view those images.

We’ll be working on adding more features to this, and making any fixes as needed. It’s open source, contributions welcome!

Also, while we’re talking about Google Camera, the upcoming CalyxOS update includes some changes that will let you install it directly from Aurora Store :)

The official CalyxOS builds are signed with our private keys. Over-the-air (OTA) updates are also signed with the same keys, and once you install the OS, only updates signed with the same key can be installed.

The builds are made from signed git tags.

Starting July 2021, all CalyxOS factory images will be signed using minisign

Why minisign? It’s dead simple, easy to use, works well with large files, and can be easily integrated with device-flasher (which will be done in a future update)

Signatures:

You can now see a new Signature column next to the download link at Get CalyxOS

You need to download both the factory zip, and the signature file (.minisig) You’ll also need the public key, minisign.pub

Then, the signature can be verified by running:

minisign -Vm sunfish-factory-2.7.1.zip -p minisign.pub
# sunfish is Pixel 4a, replace with your device

It should output:

Signature and comment signature verified
Trusted comment: CalyxOS 2.7.1 - July 2021

For more detailed instructions, see Verifying CalyxOS builds

CalyxOS Emulator images are now available, which can be used with the Emulator present in Android Studio.

They’re mostly meant for testing apps (especially system included apps such as Datura and Seedvault). They’re not meant for general usage.

URL: https://release.calyxinstitute.org/sys-img.xml

These images are userdebug which means you can use adb root.

Additionally, these aren’t separately signed, which means all the apps are signed using publicly available AOSP “test-keys”, meaning that you can easily test code changes to system apps.

x86 and x86_64 images are available currently. arm64 images appear to be currently broken in AOSP, however we’re trying to see if we can fix them. Those will be made available when ready.

Steps

This emulator image is meant for use with Android Studio

1. Launch Android Studio, and open Tools -> SDK Manager
2. Click on “SDK Update Sites”, and then tap the + plus icon on the left.
3. Type in the above url, i.e. https://release.calyxinstitute.org/sys-img.xml and under name enter “CalyxOS”
4. Make sure the checkbox to the left of “CalyxOS” is checked, and then hit Apply or OK.
5. You can now create an AVD with the CalyxOS image.
6. Open “Tools -> AVD Manager”
7. Click “Create Virtual Device” at the bottom, then select hardware.
8. Next, on the “System Image” selection page, click on “x86 Images”.
9. You should see the CalyxOS Images, they will show up as Target: Android 11 (CalyxOS Android System Image).
10. Click “Download” to download the system image, and then hit next.
11. You can now launch the AVD to run CalyxOS.

These images will get updated every month as we tag and release new builds.

sdkmanager installation

If you want to install these images using sdkmanager, the strings are:

• "system-images;android-30;calyx;x86"
• "system-images;android-30;calyx;x86_64"

Docker images

F-Droid has CI images which have the Android SDK pre-configured with our repos. They’re included in the docker image: registry.gitlab.com/fdroid/ci-images-client This means that this can be used to directly install the CalyxOS images and use it for testing / CI.

For more details see: https://gitlab.com/fdroid/ci-images-client

Matrix Space

Matrix has a new spaces features, which lets you view all these rooms together.

We’ve created a CalyxOS space.

Monthly security updates are an important tool to keep users safe and protect their devices. CalyxOS provides timely monthly updates for all supported devices. Let’s walk through how the process works.

TL;DR: CalyxOS integrates monthly updates ASAP. If you have a Pixel 3 or newer, you get the full security update. If you have a Pixel 2 or Mi A2, we are unable to update some proprietary components, but all of the open source parts are kept up to date.

AOSP

Android Open Source Project - the base for CalyxOS.

Google usually releases the security update on the first Monday of each month, which means it was May 3rd this month. This is available in two parts, one are the new builds for all support Pixel devices (Pixel 3 and newer currently), and the other is source code updates to AOSP.

That is where it starts for CalyxOS - we wait for the source code to be released to AOSP, and then get started on merging the changes into CalyxOS.

Proprietary bits

All current devices need a good sprinkling of proprietary code to even boot and have full hardware functionality. We cannot make any changes ourselves to these files, and thus we have to rely on the manufacturer to provide updates. Google provides monthly updates for all supported devices, which currently means the Pixel 3 and newer devices.

The proprietary bits can be divided into two parts:

1. Blobs

The various proprietary drivers needed for the device to work. This includes the parts needed to make the camera work, eSIM, graphics, amongst other things.

2. Firmware / Bootloader

The other part of the proprietary components, responsible for booting the device and also controlling the various components such as the modem.

Device status

CalyxOS currently supports 12 devices, and some of them have their own device-specific quirks.

Pixels 4a (5G), 5, 4a, 4 XL, 4, 3a XL, 3a, 3 XL, 3

These devices are still supported by Google, meaning they get timely monthly security updates, and thus we are able to include all the various security fixes in our builds. All components, both proprietary and open source are kept up to date by Google and hence we’re able provide all of that in our releases.

Pixels 2 XL, 2

Google stopped updating this device late 2020, which means that it no longer gets any updates for the proprietary components.

What we can update:

• The OS code, as it common for all.
• The kernel, since it’s open source.

What we cannot update further:

• The proprietary bits, both the blobs and firmware / bootloader are stuck on the October 2020 version.

Xiaomi Mi A2

The A2 being an Android One device was a big part of why we chose to support it, since it’s still getting monthly updates. However, the monthly updates aren’t always on time, usually they’re released towards the end of the month, so it lags behind a bit compared to the rest.

What we can update:

• The OS code, common for all.
• The kernel, since it’s open source.

Delayed updates:

• Proprietary blobs

We update them as soon as the update is available, but this means that it lags behind by a month or two. i.e. The May update for the A2 is still using the proprietary blobs from March 2021 since Xiaomi’s April build was delayed / pulled due to an issue, and thus we didn’t have the updates available in time.

Complicated situation:

• Proprietary firmware / bootloader.

You might have read something about needing to install Stock Oreo 8.1 before installing CalyxOS on the Mi A2 - this was needed because newer versions wouldn’t let you relock the bootloader. We worked around this in April 2021, by including just the Oreo bootloader but newer firmware into our builds. However, the newer firmware had to be from September 2020, since due to a Xiaomi bug updating to any newer (October 2020 or March 2021, doesn’t matter) results in a factory reset. This happens with the stock OS too, if you update from September to October (or newer) it asks you to factory reset.

This covers the security update situation for all supported devices. If you have any questions, feel free to ask them on one of our chat channels.

The May update introduced a new Work Profile feature, allowing you to create a work profile directly from the Settings app without having to install any third party apps.

This feature is available under Settings -> System -> Multiple users - > Add user or profile -> Work profile

However, some of you may have noticed some crashes when trying to access certain functionality within the profile. We have identified the root cause and fixed it for new profiles going forward, till then you can run the following commands from your computer to fix it right away.

Run this from a computer where you have ‘adb’ installed:

adb shell pm list users

That will output something like:

Users:
        UserInfo{0:Owner:c13} running
        UserInfo{10:New Profile:1030} running
        UserInfo{11:Guest:404}

Note the 10 here, that is the user id of the Work profile.

Now, you can run the following commands to enable certain apps in the profile to fix some of the crashing. These apps are always required to be present in the profile but were missed due to an oversight which is what caused the crashes.

Replace 10 with the user id you saw above:

adb shell pm install-existing --user 10 com.android.contacts
adb shell pm install-existing --user 10 com.android.settings
adb shell pm install-existing --user 10 com.android.providers.downloads
adb shell pm install-existing --user 10 com.android.providers.downloads.ui
adb shell pm install-existing --user 10 com.android.documentsui

This is a one time fix and won’t be required in future builds.

Our apologies for the inconvenience, and thank you for understanding!

With May comes another security update packed to the brim with new features.

Changelog:

• May Security update (2021-05-05)

A2:

• Qualcomm code updates.

Note: A2 Firmware is from September 2020 since upgrading to versions after that requires a factory reset.

CalyxOS includes microG by default, and you get three choices. You can either keep it enabled (the default), disable it, or login with a Google account.

The latter has been reported to have some issues. We tried to include a potential fix with the April build, but that didn’t work for everyone.

We have been testing a bunch of fixes and finally have something that should hopefully work for everyone. It’s based on code from Vanced microG, which from what we’ve heard seems to work for everyone.

It is now available for testing in our device-specific test F-Droid repos.

These F-Droid repositories get app updates as soon as they’re available, you can add this if you want to help us test them out.

To add it and install the update, simply add the right URL for your device to F-Droid -> Settings -> Repositories -> Plus sign at the top right

You can then try to sign-in to microG by launching it and tapping “Add Account”, and then choosing “Alt Sign in” - that will use this new method to login.

If you want to help, you can let us know what worked for you and what didn’t, through Reddit or Matrix. For more details, see Community.

F-Droid test repos:

Technical:

We enable device registration and cloud messaging for microG by default to make sure that notifications work out of the box.

The fix included in the [April build](/news/2021/04/08/big-april-update/ tried to disable those two before login, and then re-enable them after login. It seemed to work in some cases, not all.

At the same time, we had heard that Vanced microG had this Huawei login button which seemed to work for everyone. We had already looked at that code once, so we decided to try that approach.

At first, we tried to spoof just the ‘brand’ reported. AOSP sets it to Android, Google sets it to Google. Didn’t work.

Next, we thought it might be the fingerprint (which contains the build info). Both brand and fingerprint are usually spoofed on custom ROMs for Google Play compatiblity, so we thought that might be it. Tried, didn’t work.

After that we decided trying to spoof all of the device details like microG does, didn’t work.

Finally, we settled on just pulling in the full code from Vanced (something we wanted to do at first but decided to see if the other approaches worked.). This is what is being shipped in the APK now.

Note: If you take a brief look at the code, it may seem like microG is sending a lot of details about your device to Google. However, if you look closer, it spoofs a lot of that (it doesn’t even have access to things like the serial number), which means most of the data it sends to Google would match exactly with other devices, making it hard to pick you out.

Google released Chrome 90 (90.0.4430.66) yesterday, and we have updated our Chromium fork (and the patches applied on top) to pull in all the changes, and created a new build.

It is now available for testing in our test F-Droid repo, gitlab.com/CalyxOS/calyx-fdroid-repo

This F-Droid repository gets app updates as soon as they’re available, you can add this if you want to help us test them out.

To add it, simply add this URL to F-Droid -> Settings -> Repositories -> Plus sign at the top right: https://calyxos.gitlab.io/calyx-fdroid-repo/fdroid/repo?fingerprint=C44D58B4547DE5096138CB0B34A1CC99DAB3B4274412ED753FCCBFC11DC1B7B6

Alternatively, you can scan the below QR code:

Google usually does staged rollouts, where the new version will hit a small percentage of devices first, then some more, and so on.

We intend to do something similar, by adding it to this test repo first, and then later on adding it to an F-Droid repo hosted on our own servers which is already pre-added to your CalyxOS device.

Technical:

Google made a change in how they bundle Chrome since Android 10:

“Chrome is no longer used as a WebView implementation in Q+. We’ve moved to a new model for sharing common code between Chrome and WebView (called “Trichrome”) which gives the same benefits of reduced download and install size while having fewer weird special cases and bugs.”

However, the system handles this shared common code (called Trichrome Library) differently from a typical app, and as such F-Droid was not able to update it.

We submitted changes to F-Droid to allow updating of Trichrome, which have since been merged and are included in the April builds. That means we can know ship Chromium updates via F-Droid easily.

It turned out that F-Droid would have needed some system privileges to actually see the details about the “Trichrome Library” installation on the device so that it could actually update it. We didn’t want to grant any extra privileges to F-Droid itself, however we already have an F-Droid Privileged Extension which is meant exactly for something like this.

The changes:

• Client (the app): https://gitlab.com/fdroid/fdroidclient/-/merge_requests/967
• Privileged Extension (the component that allows automatic installs / background updates): https://gitlab.com/fdroid/privileged-extension/-/merge_requests/58

April is amongst us, and with it comes a security update, but wait, there’s more.

This update contains a lot of new features and bug fixes that we’ve been hard at work over the last few months. There’s even more coming in the upcoming builds, stay tuned!

Changelog:

• April Security update (2021-04-05)
• VoLTE and Wi-Fi Calling support for a lot more carriers
• microG: Potential fix for google account login issue
• Introducing Datura Firewall - our new Firewall app
• Makes the existing Wi-Fi / Mobile / VPN / Background data toggle easily accessible. More features to come!

• Include a Sensitive Phone Numbers list, hiding them from the call log.
• Dialer also gets a new helpline contact list based on the above. (Dialer -> Menu -> Helpline) for easy access. Thanks LineageOS!

• The “Background data” toggle is now able to restrict background network access completely (even when using Wi-Fi) and as such has been renamed
• Wi-Fi timeout feature - like our bluetooth timeout feature, now CalyxOS users have similar functionality to automatically turn off Wi-Fi after a certain time. Settings -> Network & Internet -> Wi-Fi -> Wi-Fi preferences -> Turn off Wi-Fi automatically
• microG: v0.2.18.204714
• Chromium: 89.0.4389.105

A2:

• Merge Xiaomi’s March 2021 Security update
• Update Kernel to 4.4.261
• Include 10.0 Firmware (September 2020)

Note: A2 Firmware is from September since upgrading to versions after that requires a factory reset.

A new experimental build has been released for the Xiaomi Mi A2 which contains firmware from the stock 10.0 release.

You may recall flashing stock Oreo 8.1 before installing CalyxOS - we now have a way to avoid doing that, and this update contains the bits updating the firmware on your existing install from 8.1 to 10.0. For new installs, factory images will be available at a later date.

Changelog:

• Merge Xiaomi’s March 2021 Security update
• Update Kernel to 4.4.261
• Include 10.0 Firmware (September 2020)

For testing this build, you need to enable USB Debugging on your device, and then run:

adb shell setprop sys.update.channel a2ten

And then, Settings -> System -> Updates -> Check for updates. That will begin downloading and then install the build.

If that doesn’t work, you can also try running:

adb shell cmd jobscheduler run --force app.seamlessupdate.client 1

So far in our testing it works well, but additional testing is always helpful and appreciated.

If you can wait, it will hit the beta channel later, and then the stable channel after that, you won’t have to do anything, your device will get the update automatically.

Additional details:

The way this works is that we included the bootloader (abl) from stock Oreo 8.1, and the rest from stock Q 10.0. The old bootloader is needed because that’s the only version that supports Verified Boot with a custom OS like ours, however we can safely upgrade the rest, to an extent.

You may have noticed the September 2020 date above, unfortunately that is due to a bug with all Xiaomi firmware after that. Updating to those from any older build results in needing a factory reset - you simply cannot upgrade without wiping data. This is not desirable, and hence for now we’ve included the last working firmware where this wasn’t required.

A build with a charging fix for the Xiaomi Mi A2 has been released.

There are no other changes, which means it’s a very small update - only 609 Kb for the incremental OTA update.

The March Security update is now available for all supported devices.

You can follow these instructions to install.

Do let us know if you face any issues or bugs.

Yippie! We have a new website. It is static generated and anyone can contribute through gerrit. See [[gitlab.com/CalyxOS/calyxos.org]] and https://review.calyxos.org/q/project:CalyxOS/calyxos.org.

In the coming weeks, we will be adding help documentation, tutorials, release change logs, and more. Stay tuned!

The April 2020 build of Calyxos (build 2020.04.07.17) did not include the OTA Updater due to a misconfiguration.

This means that it will not update to the May build by itself, you need to follow two quick manual steps:

1) Open F-Droid, pull down to refresh the repositories. After the refresh completes , check the updates list. You’ll see an update for “Seamless Update Client”, install that update.

2) Open the newly updated “Updater” app. It’ll ask you “Let app always run in background?”, please hit allow, and then it will start updating the system
