SELinux This release comes with SELinux in permissive mode for easy debugging / customization. Note that this feature only works on userdebug builds, user builds are enforced at all time. AVB2.0 The image also supports Android Verified Boot 2.0! So I can’t make any modification now? No, there’s a way to disable verity for userdebug builds: $ adb root $ adb disable-verity $ adb reboot At this point you will be able to modify every partition. However, it goes without saying that this disablement isn’t possible on user builds. Linux Kernel 5.15.x This Android release is based on a 5.15.x kernel from MediaTek. For those familiar with the Yocto 5.15 kernel, know that the Android version is quite different as its architecture is meant to support Android Generic Kernel Image (GKI) images.
