The Poco F3 (Alioth) continues to age like fine wine in the custom ROM world, and the arrival of LineageOS Ext (Community build) based on Android 16 is another solid example of why this device still has a thriving developer community. Updated on 14 December 2025, this ROM takes the clean and trusted LineageOS base and extends it with a wide range of useful, modern, and power-user-friendly features.
Unlike heavy OEM skins or experimental ROMs that try to do too much, LineageOS Ext focuses on practical customization, system control, and user freedom—while keeping the core experience smooth and stable. It’s not just LineageOS with a few toggles added; it’s a carefully extended build aimed at people who actually use their phone daily and want more control without chaos.
In this article, we’ll go through what LineageOS Ext offers, how it feels in real use, what features stand out, and who this ROM is best suited for.
What Is LineageOS Ext?
LineageOS Ext is a community-maintained fork of LineageOS, built on Android 16 and enhanced with additional features that are not part of official LineageOS. The goal is simple: keep LineageOS’ clean foundation intact while adding the kind of controls and tweaks users usually install mods for.
This build is maintained for Alioth (Poco F3 / Redmi K40 / Mi 11X) and comes in both GApps and Vanilla variants, giving users the freedom to choose how minimal or complete they want their setup to be.
