We’ve seen a lot of unauthorized LineageOS 19 builds based on Android 12 over the past several months, but this third-party ROM is now formally available.
One of the most well-liked third-party ROMs for Android, LineageOS 19 brings a significant update that was announced in an official blog post. The official upgrade is really based on Android 12.1/12L, however as Android has switched to quarterly maintenance releases, the team has chosen to omit 19.1 in favor of 19.
This version will be LineageOS 19, not 19.0 or 19.1, as Android has switched to the quarterly maintenance release schedule.
Along with 29 other phones, LineageOS 19 will debut initially for a number of Google Pixel devices. Sadly, there are currently no builds available for the Pixel 6 and Pixel 6 Pro with Google Tensor. As those responsible for maintaining specific device builds provide updates, more devices will be added. As you can see below, the official changelog is quite extensive.
CHANGELOG FOR LINEAGEOS 19 UPDATE LineageOS 16.0 through 19 have been updated with security updates from March 2021 to April 2022. 19 builds are now based on the Android-12.1.0 r4 tag, which is the Pixel 6 series tag. The most recent version of WebView is Chromium 100.0.4896.58. The volume panel that was first introduced in Android 12 has been totally redesigned and is now a side pop-out expanding panel. Numerous fixes and enhancements have been made to the AOSP Gallery app in our fork. Numerous bug fixes and enhancements have been made to our Updater application. Numerous bug fixes and enhancements have been made to our web browser, Jelly! We just integrated a FOSS Etar calendar app, and we’ve since donated a number of updates and enhancements back upstream! We have added a lot of modifications and enhancements to the Seedvault backup software back upstream. Numerous bug repairs, enhancements, and feature additions have been made to our Recorder app. In contrast to Google’s ad-enabled launcher, Android TV builds now come with an ad-free Android TV launcher. A key-handler is now included in Android TV versions, allowing us to support custom keys on a variety of bluetooth and IR remotes. The build type property is no longer connected to our adb root service. Our extract utilities now enable extraction from the majority of factory images and bundled OTA images, substantially streamlining device setup and blob extraction. Our SDK now includes support for high-touch polling rate, enabling its use on compatible devices. We now compile our kernels by default using the AOSP Clang toolchain. Devices that formerly utilized Qualcomm’s Snapdragon Camera will now use Camera2. The dark mode is now always on. We now have an entirely new Setup Wizard with animations, icons, and a ton of new configurable pages designed in the manner of Android 12! Almost all of our applications, including system ones, have brand-new sets of icons! (18.1 too) Check out the new default wallpaper and the full collection of wallpapers we have available! Try these wallpapers out to discover which accent color you prefer—they were created with Android 12’s Monet theming tools in mind. (18.1 too) All devices that opt-in can use Wi-Fi display, either through the Qualcomm-exclusive interface or the recently revived traditional Miracast interface! We now allow custom charging noises for both cabled and wireless charging (18.1 too). Networking is affected by a number of additional changes in LineageOS 19. To be compliant with AOSP’s new restricted networking mode, a redesign of the privacy-focused built-in firewall, restricted networking mode, and per-app isolation features was required.
Sadly, some legacy devices might not be updated to LineageOS 19 for the time being due to several other AOSP changes, namely the removal of iptables in favor of eBPF . The LineageOS team gave the following justification:
The problem is that only systems running the Linux kernel 4.9 or newer have the necessary capability to use eBPF. Normally, these features can be backported to earlier kernel versions, but at the present, even 4.4, which is quite near to kernel version 4.9, proved difficult because of the enormous number of commits and structural changes brought about by the introduction of BPF. Fear not, 4.4 kernel users—a backport has been made. However, for devices running kernel 3.18 and before, this may be the end of the road.
The complete list of supported hardware can be seen on the official Lineage Wiki or in the blog post for the dedicated build roster if you want to download and install LineageOS 19 on your device.
