This note is to all Android enthusiasts who want to equip their smartphones with LineageOS (a modification of Android and the successor of the discontinued Android custom ROM CyanogenMod). The makers have released version 19 based on Android 12. Of course, there are a few innovations, but also security improvements.
For example, WebView has been brought up to the level of Chromium 100.0.4896.58 and the security patches from March 2021 to April 2022 have been packaged in Lineage versions 16 to 19. So you are very well positioned. They have also completely revised the volume control panel introduced in Android 12 and instead implemented a laterally fold-out panel.
But there is also bad news, so you won’t be able to support as many old devices as many might have expected. This is because in the AOSP Android Open Source Project) iptables have been removed in favor of eBPF.
This is a newer, much more efficient kernel-side implementation. Devices that use kernel versions 3.18 and below could be “out” according to initial predictions. Interested users, perhaps those who still have an old device in their drawer, will find all the information here.
