AXP.OS

AXP.OS is a privacy- and security-focused aftermarket mobile operating system based on AOSP and LineageOS. It aims to keep supported Android devices, including some end-of-life models, usable for longer with hardening patches, verified updates, and project-maintained components such as AOSmium and AXP.OS F-Droid repositories; the project offers Slim and Pro flavors for users who want different tradeoffs between minimalism and extra functionality.
